Claims
- 1. In a gravity cross-flow separator of the type comprising mutually parallel spaced-apart plates defining a substantially horizontal liquid flow path between each pair of adjacent plates for passing a liquid to be treated by gravity separation, said plates being inclined relative to a horizontal place and defining upper and lower gutters extending substantially in the direction of greatest inclination of said plates and transversely to the direction of liquid flow for collecting components separated from the treated liquid disposed above and below said flow path, respectively, wherein the improvement comprises that said gutters have substantially trapezoidal or rectangular cross section so as to substantially contain separated material in said gutters against entrainment with said horizontal liquid flow, the upper gutters of each flow path being in phase alignment with the lower gutters of the same flow path.
- 2. The device of claim 1 wherein said plates are spaced apart sufficiently in relation to the depth of said gutters and the viscosity of the fluid flow so as to maintain substantially linear flow of liquid between the plates.
- 3. In a gravity cross-flow separator of the type comprising mutually parallel spaced-apart plates defining a substantially horizontal liquid flow path between each pair of adjacent plates for passing a liquid to be treated by gravity separation, said plates being inclined relative to a horizontal plane and defining upper and lower gutters extending substantially in the direction of the greatest inclination of said plates and transversely to the direction of liquid flow for collecting components separated from the treated liquid disposed above and below said flow path, respectively, wherein the improvement comprises that said plates are spaced apart sufficiently in relation to the depth of said gutters and the viscosity of the fluid flow so as to maintain a substantially linear flow of liquid between the plates; and
- wherein said plates are substantially plane and said gutters have a substantially rectangular cross-section and are defined by upstanding ridges provided on both sides of each of said plates, said ridges on opposite sides of said plates being substantially aligned with each other.
- 4. In a gravity cross-flow separator of the type comprising mutually parallel spaced-apart plates defining a substantially horizontal liquid flow path between each pair of adjacent plates for passing a liquid to be treated by gravity separation, said plates being inclined relative to a horizontal plane and defining upper and lower gutters extending substantially in the direction of the greatest inclination of said plates and transversely to the direction of liquid flow for collecting components separated from the treated liquid disposed above and below said flow path, respectively, wherein the improvement comprises that said plates are spaced apart sufficiently in relation to the depth of said gutters and the viscosity of the fluid flow so as to maintain a substantially linear flow of liquid between the plates; and
- wherein said gutters are defined by corrugations in said plates, said corrugations having substantially trapezoidal cross-sections, the corrugations in each pair of adjacent plates being arranged in phase opposition.
