The present invention in general relates to a fluid treatment structure (i.e. a cartridge assembly) for the treatment of a fluid (e.g. a fluid medium) comprising two or more components whereby two or more of the components may be separated or isolated one from the other. The fluid (e.g. liquid) treatment structure may, in particular, be used to enclose solid matter (e.g. a particulate matter) for the treatment of a fluid. The fluid treatment structure may, for example, be used in a system or process for the treatment of a gas (such as for example air to remove particles therefrom) or a liquid (such as for example a liquid medium comprising oil and water). The fluid treatment structure may, for example, be used for the treatment of an oil/water, medium or substance (e.g. an emulsion) for the separation of oil from water, the oil/water medium (i.e. emulsion), being a liquid, medium or substance, wherein oil is the dispersed phase and water is the continuous phase (i.e. an emulsion wherein water is the continuous phase).
The fluid treatment structure will, by way of example only, be described in relation to a liquid (e.g. an emulsion).
It is to be understood herein that the term “oil” means any organic liquid which is substantially immiscible with water and which either has a specific gravity appreciably from that of water or which exhibits such difference when the specific gravity of the water is altered by a solute dissolved therein.
Oil from water separators are known and include, for example, coalescing separators (see for example Canadian patent nos. 1,093,478 and 1,167,774 and U.S. Pat. No. 4,102,785). For example one means for the separation of oil from an oil/water medium (i.e. emulsion) involves the use of a coalescing type filter or separator designed for “inside to outside flow”. For this “inside to outside flow” technique an oil/water medium (i.e. emulsion) may be passed (radially) through the body of an annular coalescent bed from “inside to outside”. As the oil/water medium passes through the coalescent bed oil droplets are coalesced and an oil phase separates from the water passing through the coalescent bed. Thus oil from water separator may comprise a cartridge assembly having an annular coalescing section to cause emulsified liquids to form readily removable oil droplets in the flow. As may be appreciated various wall elements of these known separators are liquid permeable.
It would be advantageous to have a fluid (e.g. liquid) treatment cartridge unit (e.g. housing, assembly, etc.) which may be readily assembled from various elements by exploiting relatively simple mechanical interconnection means, i.e. by means which do not necessarily require the use of an adhesive, a weld, a solder joint, etc. It would in particular be advantageous if a cartridge assembly may be built up from molded (plastics) components. It would further be advantageous if a cartridge unit could be broken down into its constituent components in order to facilitate reuse of the cartridge unit, i.e. refill of the cartridge unit. It would be advantageous to have a relatively compact separator system having at least one cartridge tower, the cartridge tower comprising at least one cartridge unit held in place by a relatively simple cartridge attachment mechanism.
The present invention in a general aspect relates to a fluid (e.g. liquid) treatment cartridge assembly for holding solid material defining a fluid permeable body (e.g. a body of particulate material) therein for contact with a fluid (e.g. a liquid substance). The cartridge assembly comprises an outer cylindrical housing component, having a first cylindrical axis, and an inner tubular component disposed within the cylindrical housing component. The outer cylindrical housing component includes a plurality of wall panels which are interconnected. Each wall panel may be provided with respective wall interconnect means whereby adjacent wall panels are releasably interlocked. The wall panels may, for example, be interconnected by slider interlock means disposed and configured such that adjacent wall panels are slide interlocked thereby. The outer cylindrical housing component and the inner tubular component may each have a liquid permeable aspect over at least a portion thereof for allowing fluid (e.g. liquid) to pass therethrough; the outer cylindrical housing component and the inner tubular component may, for example, each have a foraminous aspect.
The present invention in accordance with an aspect provides a fluid (e.g. liquid) treatment cartridge assembly for holding solid material defining a fluid permeable body (e.g. a body of particulate material) for contact with a fluid (e.g. a liquid), said cartridge assembly comprising:
an outer cylindrical housing component (e.g. enclosure, casing, etc.) having a first cylindrical axis
and
an inner tubular component disposed within said cylindrical housing component,
said outer cylindrical housing component comprising a first cap element, a second cap element and a cylindrical enclosure wall element, said cylindrical enclosure wall element terminating in opposed ends, one of said opposed ends being closed off by said first cap element and the other opposed end being closed off by said second cap element,
said inner tubular component having a first end member, a second end member and a tubular wall member extending from said first end member to said second end member, said inner tubular component defining an interior channel, said tubular wall member being fluid (e.g. liquid) permeable,
and
wherein said outer cylindrical housing component and said inner tubular component define a holding chamber therebetween for holding said solid material,
wherein said first cap defines a first opening extending therethrough, the first end member of said inner tubular component being connected to said first cap element such that said first opening is in fluid (e.g. liquid) communication with said interior channel of said inner tubular component,
wherein said cylindrical enclosure wall element comprises a plurality (i.e. two or more) of interconnected wall panels, each of said wall panels extending from one said opposed end to the other said opposed end of said cylindrical enclosure wall element, at least one of said wall panels being fluid (e.g. liquid) permeable, each wall panel being provided with respective wall interconnect means whereby adjacent wall panels are releasably interlocked.
The wall interconnect means (of the wall panels) may take on any suitable (i.e. desired or necessary) form. The wall interconnect means may, for example, take on the form of slider interlock means disposed and configured such that adjacent wall panels are slide interlocked thereby, i.e. the slider interlock means may comprise a first slider interlock element and an opposed second-slider interlock element.
Thus the present invention in accordance with the cartridge assembly aspect in particular provides a fluid (e.g. liquid) treatment cartridge assembly for holding solid material defining a fluid permeable body (e.g. a body of particulate material) therein for contact with a fluid (e.g. a liquid), said cartridge assembly comprising:
an outer cylindrical housing component (e.g. enclosure, casing, etc.) having a first cylindrical axis
and
an inner tubular component disposed within said cylindrical housing component,
said outer cylindrical housing component comprising a first cap element, a second cap element and a cylindrical enclosure wall element, said cylindrical enclosure wall element terminating in opposed ends, one of said opposed ends being closed off by said first cap element and the other opposed end being closed off by said second cap element,
said inner tubular component having a first end member, a second end member and a tubular wall member extending from said first end member to said second end member, said inner tubular component defining an interior channel, said tubular wall member being fluid (e.g. liquid) permeable,
and
wherein said outer cylindrical housing component and said inner tubular component define a holding chamber therebetween for holding said solid material,
wherein said first cap element defines a first opening extending therethrough, the first end member of said inner tubular component being connected to said first cap element such that said first opening is in fluid (e.g. liquid) communication with said interior channel of said inner tubular component
wherein said cylindrical enclosure wall element comprises a plurality (i.e. two or more) of interconnected wall panels, each of said wall panels extending from one said opposed end to the other said opposed end of said cylindrical enclosure wall element, at least one of said wall panels being fluid (e.g. liquid) permeable,
wherein each wall panel is provided with a first slider interlock element (e.g. disposed parallel to said first cylindrical axis) and an opposed second slider interlock element (e.g. disposed parallel to said first cylindrical axis), said first and second slider interlock elements being disposed and configured such that adjacent wall panels are slide interlocked by respective first and second slider interlock elements.
In accordance with the present invention a fluid (e.g. liquid) treatment cartridge assembly is provided wherein the inner tubular component may have a tubular axis coterminous with said cylindrical axis and the second end of the tubular wall member second may be connected to the second cap element. More generally, however, the tubular axis and the cylindrical axis may be parallel or non-parallel one to the other. Thus, alternatively, for example, as desired or necessary, the tubular axis and the cylindrical axis may be space apart and may be parallel or non-parallel one to the other. The disposition of the tubular axis and the cylindrical axis is of course to be selected keeping in mind the nature of the cartridge assembly, i.e. a fluid treatment cartridge assembly.
In accordance with the present invention a fluid (e.g. liquid) treatment cartridge assembly is provided wherein the second cap element may define a second opening extending therethrough, the second end member of the inner tubular component being connected to the second cap element such that the interior channel of the inner tubular component is in fluid (e.g. liquid) communication with the second opening.
Thus as may be appreciated from the above, in accordance with the present invention a fluid (e.g. liquid) treatment cartridge assembly is provided wherein the first and the second cap elements are each connected to the cylindrical enclosure wall element, i.e. by respective connection means. Furthermore the first cap element, (and where desired or necessary, the second cap element) is (are) also connected to the inner tubular component, i.e. again by respective connection means. The respective connection means may take on any desired or necessary form and may, for example, be releasable connection means. The first end cap and the second end cap may for example be each connected to the inner tubular component by respective press fit type connection means (see below), screw thread type connection means, key lock type connection means (i.e. having male and female interlock elements) etc.
In accordance with the present invention a fluid (e.g. liquid) treatment cartridge assembly is provided wherein each of the opposed ends of the cylindrical enclosure wall element may comprise a first lock component and the first and second cap elements each may comprise a respective second lock component. Each first lock component and a respective second lock component may be configured such that the first and second cap elements are interlocked (e.g. releasably interlocked) thereby to a respective opposed end of the cylindrical enclosure wall element. Such interlocking of the cap elements and the enclosure wall element may take on any desired or necessary form provided that separation of the elements is inhibited, e.g. the interlocking means inhibits relative axial displacement of the cap elements relative to the cylindrical enclosure wall element; the interlocking means may for example be a screw thread type connection means, key lock type connection means, etc.
In particular in accordance with the present invention a fluid (e.g. liquid) treatment cartridge assembly is provided wherein each of the opposed ends of the cylindrical enclosure wall element may comprise a first snap lock component and the first and second cap elements each may comprise a respective second snap lock component. Each first snap lock component and a respective second snap lock component may be configured such that the first and second cap elements may be interlocked thereby to a respective opposed end of the cylindrical enclosure wall element.
In particular, in accordance with the present invention a fluid (e.g. liquid) treatment cartridge assembly may be provided wherein each of the second snap lock components may comprise a plurality of respective resilient snap lock male elements and each of the first snap lock components may comprise a plurality of lock sockets for receiving a respective resilient snap lock male element; the male elements may be biased in any manner so as to tend to be in a lock configuration or position. The cap and wall elements may, furthermore, as desired or necessary be releasably interlocked. Thus the lock sockets and resilient snap lock male elements may be configured such that the male elements may be manually displaced (e.g. pushed back against their lock biasing action) such that the male elements may be cleared of the lock sockets such that the cap elements may be separated from the wall element.
In accordance with the present invention a fluid (e.g. liquid) treatment cartridge assembly is provided wherein for each wall panel, one of said slider interlock elements comprises a straight side edge male projection member and the other slider interlock elements comprises a straight side edge female slot member parallel to said straight side edge male member, said straight side edge male projection member and said straight side edge female slot member being disposed and configured such that adjacent wall panels have been interconnected by sliding the straight side edge male projection member of one wall panel in the straight side edge female slot member of an adjacent wall panel.
In accordance with the present invention a fluid (e.g. liquid) treatment cartridge assembly is provided wherein each panel may be a foraminous wall panel, namely each panel may be a perforated body having (i.e. provided with a plurality of) suitable apertures for the flow of fluid (e.g. liquid) therethrough (i.e. each of the wall panels is fluid (e.g. liquid) permeable). Similarly, the tubular wall member of the inner tubular component may be a foraminous tubular wall member. Foraminous wall panels and a formainous tubular wall member are shown in the figures discussed below.
The present invention in accordance with another aspect provides a wall panel for a cylindrical enclosure wall element of a cylindrical housing comprising a pair of end cap elements, said wall panel having opposed ends disposed transverse to first and second opposed slider interlock elements, said first slider interlock element being disposed parallel to said opposed second slider interlock element, said first and second slider interlock elements being disposed and configured such that adjacent wall panels are interlockeable by respective first and second slider interlock elements by sliding one slider interlock element in the other and wherein each of said opposed ends comprises a first lock element configured for interlocking (e.g. releasably interlocking) with a respective second lock element of a respective cap element. The wall panel, as desired or necessary, may or may not be fluid permeable.
In accordance with the present invention a wall panel is provided wherein each of said opposed ends may comprise a first snap lock element configured for interlocking with a respective second snap lock element of a respective cap element. In accordance with the present invention a wall panel is provided wherein each of the second snap lock elements may comprise a resilient snap lock male member and each of said first snap lock elements comprises a lock socket for receiving a respective resilient snap lock male member.
In accordance with the present invention a wall panel is provided wherein the wall panel may be a foraminous wall panel, namely the panel may be a perforated body having (i.e. provided with a plurality of) suitable apertures for the flow of fluid (e.g. liquid) therethrough (i.e. the wall panel is fluid (e.g. liquid) permeable).
The present invention additionally provides a cylindrical enclosure wall comprising a plurality of slide interlocked wall panels, the wall panels being as described with respect to the above mentioned wall panel aspect of the present invention.
The present invention further provides a kit for creating a cylindrical enclosure wall comprising a plurality of slide interlocked wall panels, said kit comprising a plurality of wall panels as described with respect to the above mentioned wall panel aspect of the present invention.

a plurality of interconnectable wall panels for defining a cylindrical enclosure wall element, at least one of said wall panels being fluid (e.g. liquid) permeable,
a first cap element and a second cap element, for defining, along with said cylindrical enclosure wall element, said outer cylindrical housing component,
said inner tubular component, said wall panels, said first cap element and said second cap element being configured for forming a cartridge assembly, said cartridge assembly being an assembly,
wherein said cylindrical enclosure wall element terminates in opposed ends, one of said opposed ends being closed off by said first cap element and the other opposed end being closed off by said second cap element,

wherein each of said wall panels is able to extend from one said opposed end to the other said opposed end of said cylindrical enclosure wall element,
and
wherein each wall panel is provided with a first slider interlock element (e.g. disposed parallel to said cylindrical axis) and an opposed second slider interlock element (e.g. disposed parallel to said cylindrical axis), said first and second slider interlock elements being disposed and configured such that adjacent wall panels are slide interlockable by respective first and second slider interlock elements.
In accordance with the present invention a kit is provided wherein for each of said wall panels, one of said slider interlock elements comprises a straight side edge male projection member and the other slider interlock element comprises a straight side edge female slot member parallel to said straight side edge male projection member, said straight side edge male projection member and said straight side edge female slot member being disposed and configured such that the straight side edge male projection member of one wall panel is able to slide in the straight side edge female slot member of an adjacent wall panel so at to be able thereby to slide interconnect the adjacent panels.
In accordance with the present invention a kit may comprise foraminous wall panels as described herein, and, if present, a foraminous tubular wall member.
As a further aspect the present invention relates to a separator system for the separation of an immiscible liquid (e.g. oil) from water (e.g. an oil in water liquid medium), the system comprising at least one cartridge tower (as described herein) the cartridge tower comprising at least one cartridge assembly as described herein. A clamp type cartridge attachment means, an example of which is described herein, may be used to maintain the cartridge tower(s) in place in the separator system (e.g. so that the cartridge assembly(ies) thereof are in liquid communication with liquid medium inlet means (e.g. pipe(s), chamber(s), etc.). The clamp type cartridge attachment means may connect a cartridge tower to a suitable liquid medium input means.
Thus in accordance with the above mentioned further aspect the present invention also provides a separator system for the separation of a water immiscible liquid (e.g. oil) from a liquid medium comprising water and the water immiscible liquid (e.g. oil) wherein water is the continuous phase, the system comprising at least one cartridge tower for the separation of said water immiscible liquid from the liquid medium, the cartridge tower comprising one or more cartridge assemblies and clamp type cartridge attachment means for connecting each of said cartridge assemblies to liquid medium inlet means so that each of said cartridge assemblies are in liquid communication with said liquid medium inlet means, each of said cartridge assemblies being charged with a predetermined particulate material defining a liquid permeable coalescent body, said cartridge assembly being a cartridge assembly as defined herein, said liquid medium inlet means being in liquid communication with the interior channel the inner tubular component of said cartridge assemblies. The clamp type cartridge attachment means may take on any desired or necessary form and may for example take the form discussed herein below.
It is to be understood herein that the expressions “slide interlockable”, “slide interlocked” “slide interconnect” or the like in relation to “slider interlock means”, “first and second slider interlock elements”, and the like, refer to an interconnection between the wall panels whereby displacement of the wall panels is inhibited in a non-sliding direction. In other words, these expressions refer, for example, to an interconnection between the wall panels whereby displacement of the wall panels transverse to the cylindrical axis (or, for example, transverse to the parallel wall interlock elements themselves, if the wall panels are provided with parallel interlock elements) is inhibited by the slider interlock means, the slider interlock elements, or the like; on the other hand, unless otherwise inhibited, displacement, for example, parallel to the cylindrical axis (or if present, parallel to parallel interlock elements) is not inhibited by the slider interlock means, the slide interlock elements or the like.
It is also to be understood herein that the expressions “fluid permeable”, “ liquid permeable”, “gas permeable”, or the like as they relate to a body, a bed, a wall member, a wall panel or the like, characterizes the body, the bed, the wall member, the wall panel or the like, as having openings of any desired, necessary or sufficient, number, configuration, size, etc. for allowing the desired or necessary passage therethrough of a fluid (e.g. the liquid components of an emulsion such as a water component and an oil component of a water/oil emulsion); e.g. a fluid permeable wall element is a wall element interrupted with openings sufficient to allow the desired passage therethrough of a fluid (i.e. a liquid such as a water/oil emulsion). The openings are of course also to be sized keeping in mind the nature of the solid material defining the fluid permeable body or bed which may be held for example by a cartridge assembly. If the cartridge assembly is to hold particulate material, the nature, disposition and number of (wall) openings may be determined (i.e. empirically) by keeping in mind that any openings should inhibit passage therethrough of the particulate material making up the fluid peremeable bed or body. i.e. wall panel openings may be configured such that the wall panels may maintain the desired integrity of the bed or body.
In accordance with the present invention the outer cylindrical housing component and the inner tubular component may for example define an annular holding chamber for holding solid material defining a fluid permeable body or bed. The annular holding chamber may, for example, be charged or filed with a desired particulate material. Thus, for example, the cartridge assembly may be charged with a coalescing medium for causing a liquid component of a liquid mixture (e.g. emulsion) to be separated or removed from the mixture by being coalesced into droplets. The particulate material may, for example, be of a (coalescent particulate) material of the type(s) described in Canadian patent application no. 2,511,884; for an additional description of possible types of materials please see Canadian patent nos. 2,085,951 and 2,421,076 as well as U.S. Pat. No. 5,239,040. The entire contents of each of these Canadian and U.S. patent documents are incorporated herein by reference.
It is thus also to be understood herein that the expressions “coalescent bed”, “coalescent body” or the like refer to a coalescent bed, body or the like which is able to facilitate the coalescence, for example, of water immiscible liquid droplets (e.g. oil droplets) from an emulsion comprising the water immiscible liquid (e.g. oil) in water (i.e. water being the continuous phase).

The separator system may comprise a clamp type cartridge attachment means or mechanism, as shown, which includes a cartridge support anchor component and a cartridge attachment component respective generally, indicated by the reference numerals 62 and 64. The clamp type cartridge attachment mechanism also includes an interconnection shaft member 66 whereby one or more cartridge assemblies (see
The interconnection shaft member 66 has two externally threaded opposed ends 68 and 70. The interconnection shaft member 66 also has three equally spaced baffle or wing members 72 which extend radially outwardly from the shaft body of the interconnection shaft member 66. The baffle members 72 also extend longitudinally parallel to the longitudinal axis of the interconnection shaft member 66.
The cartridge support anchor component 62 is hollow and has an outer peripheral wall 74.
An opening end of the outer peripheral wall 74 of the cartridge support anchor component 62 is connected or attached to the common wall 59 about the common wall opening 60 in liquid (i.e. water) tight fashion so as to inhibit leaks thereabout (e.g. by a suitable weld 76 in the case where both the common wall and the peripheral wall are of metal). Liquid medium in the inlet chamber thus has access to the interior of the cartridge support anchor component 62, defined by the outer peripheral wall 74, through the common wall opening 60.
The other end of the cartridge support anchor component is provided with an annular gasket engagement platform 77; this platform has a central opening 77a. The annular gasket engagement platform 77 is disposed so as to engage an annular gasket (e.g. rubber gasket) attached to a cartridge assembly of the present invention.

Turning back to
The cartridge attachment component has a rotatable compression adjustment member 100 which has an opening 102 for receiving the other end 70 of the interconnection shaft member 66. The opening 102 of the rotatable compression adjustment member is provided with interior screw threads for screw engagement with the screw threads of the end 70 of the interconnection shaft member 66.
The cartridge attachment component includes a compression spring 104 disposed about the interconnection shaft member 66 between the rotatable compression adjustment member 100 and a compression engagement member 106.
The compression engagement member 106 has an opening through which the interconnection shaft member 66 may pass for engagement with the compression adjustment member 100. The compression engagement member 106 has an annular shoulder member 108 for (compression) engagement with the upper annular gasket 78 attached to the immediately adjacent cartridge assembly.
The cartridge attachment component also has a sleeve member 110 and a washer member 112 which are rotatable about the longitudinal axis of the interconnection shaft member 66.
As may be appreciated the direction of rotation of the compression adjustment member 100 will determine the degree of compression to which the cartridge assembly(ies) are subjected; during operation sufficient compression is to be applied so as to provide liquid (i.e. water) tight interconnection between adjacent cartridge assemblies and between the cartridge assembly(ies) and the adjacent cartridge support anchor component and the adjacent cartridge attachment component.
