Description

TECHNICAL FIELD

The present disclosure relates to a system including a compressor and a method of sealing the compressor.

BACKGROUND

A compressor, such as a centrifugal gas compressor, is a commonly used compression device that compresses a low-pressure gas into a high-pressure gas. The compressor includes one or more vanes or impellers that can be driven by a power source via a shaft that allows the compressor to compress various gases.

Typically, the compressor includes a body within which various components of the compressor are disposed. Further, one or more end caps are coupled to the body of the compressor to enclose the components and gases within the body. The end caps are disposed at both ends of the body. The compressor further includes a sealing member disposed between each end cap and the body to prevent leakage of gases through a gap between the end cap and the body. However, due to defects or deterioration of the sealing members, gases may leak through the gap and may be let into the atmosphere. Since the gases being compressed by the compressor may be flammable and/or toxic in nature, the leakage of such gases may lead to an undesirable increase in green-house effect and may also cause undesirable detonation and/or ignition or other undesirable issues.

CN112177950 discloses a circulating centrifugal gas compressor and relates to the technical field of compressors. The circulating centrifugal gas compressor comprises a gas compressor housing, a waterproof fixed base and a hollow telescopic housing, wherein the gas compressor housing and the hollow telescopic housing are both fixedly installed at the top of the waterproof fixed base; the gas compressor housing is located in the hollow telescopic housing; a lifting top plate is fixedly installed at the top of the hollow telescopic housing; a multi-cavity filter box is fixedly installed at the top of the lifting top plate; a water storage tank for telescopic adjustment is fixedly installed at one side of the waterproof fixing base; and a driving water pump is fixedly installed at the top of the water storage tank for telescopic adjustment. According to the invention, a vacuum cavity is formed, and a vacuum pump is matched for vacuumizing in advance before use, so that the purity of compressed gas is guaranteed; different gases can be filtered during compression by matching the multi-cavity filter box with the lifting top plate, so that more use requirements are met; and meanwhile, the hollow telescopic housing is arranged in a water pressure driving mode to achieve lifting, so that a better noise reduction effect is achieved.

DETAILED DESCRIPTION

Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

Referring to FIG. 1, a schematic perspective view of a system 100 is illustrated. The system 100 includes a compressor 200. The compressor 200 includes a center body 202. The compressor 200 defines a central axis A1. The center body 202 extends along the central axis A1 and forms a hollow interior. The compressor 200 also defines a first end 208 and a second end 210 opposite the first end 208.

The center body 202 includes a suction port 204 and a discharge port 206. Each of the suction port 204 and the discharge port 206 are spaced apart from the first end 208 and the second end 210, respectively. Gases to be compressed may enter the compressor 200 via the suction port 204. The compressor 200 further includes one or more impellers (not shown) disposed inside the center body 202. The impellers may be connected to a power source (not shown) via a shaft (not shown) that imparts rotation to the impellers. The gases entering through the suction port 204 are compressed by the impellers. The compressed gases exit the compressor 200 through the discharge port 206 of the center body 202. In some examples, the gases may include ammonia gases, propylene, natural gases, rich petroleum gases, carbon monoxide, methanol, ethylene, hydrogen, and the like.

It should be noted that the compressor 200 may be used in industrial production and equipment preparation processes, such as an oil refining and chemical system, a refrigeration system, a fuel cell engine, a gas turbine engine, a wastewater treatment station, a factory gas station, a laboratory gas supply, and the like. The compressor 200 may be embodied as a centrifugal gas compressor that may compress low pressure gases into high pressure gases. Alternatively, the compressor 200 may be embodied as an axial compressor, or any other type of compressor. In some examples, the compressor 200 may have one or more stages of compression for improving a pressure ratio of compression. For example, the compressor 200 may include a double-stage compressor that may be formed by connecting two single-stage compressors in series and may be used for improving the pressure ratio of compression.

FIG. 2 is a sectional side view of the compressor 200 associated with the system 100 of FIG. 1. The compressor 200 includes an end cap 212, 213 coupled to the center body 202 at a connection interface 214, 215, respectively. The end cap 212, 213 may be disposed at least partially within the center body 202. It should be noted that the compressor 200 includes two end caps 212, 213 herein. Particularly, one end cap 212 is disposed at the first end 208 and another end cap 213 is disposed at the second end 210 of the compressor 200. In some examples, the end caps 212, 213 may be coupled to the center body 202 at the corresponding connection interface 214, 215 via one or more fastening elements (not shown). In some examples, the fastening elements may include a bolt, a screw, a rivet, or the like. In some examples, the end caps 212, 213 may be made of a metallic material, a polymeric material or a combination of both.

Further, a sealing member 211, 217 may be disposed between the center body 202 and the corresponding end cap 212, 213 and to seal the connection interface 214, 215. The sealing members 211, 217 may prevent leakage of gases into the atmosphere, via the connection interface 214, 215. However, in some cases, due to defects or deterioration of the sealing members 211, 217, gases may leak through the connection interface 214, 215 and may be let into the atmosphere. Since the gases being compressed by the compressor 200 may be flammable and/or toxic in nature, the leakage of such gases may lead to an undesirable increase in green-house effect and there may be a possibility of undesirable ignition or other undesirable issues.

Thus, the present disclosure relates to a sealing system 216 that seals and captures the gases leaking/slipping through the connection interface 214, 215 and/or the sealing members 211, 217. Specifically, the compressor 200 includes the sealing system 216. The sealing system 216 includes an annular duct 218, 219 circumferentially extending along the connection interface 214, 215 between the center body 202 and the end cap 212, 213, respectively. The annular duct 218, 219 is concentrically disposed along a periphery of the end cap 212, 213 of the compressor 200 in relation to the central axis A1 of the compressor 200. In the illustrated example of FIG. 2, the annular duct 218 is disposed at the first end 208 of the compressor 200 and the annular duct 219 is disposed at the second end 210 of the compressor 200.

Referring to FIG. 3, a perspective sectional front and side view of a portion of the compressor 200 is illustrated. As shown in FIGS. 2 and 3, the annular duct 218 defines a chamber 232. The chamber 232 is in fluid communication with the connection interface 214 and captures any gases leaking through the connection interface 214 therein.

Referring again to FIG. 2, the annular duct 219 defines a chamber 234. The chamber 234 is in fluid communication with the connection interface 215 and captures any gases leaking through the connection interface 215 therein.

Further, the sealing system 216 also includes a conduit 220, 221 coupled to the annular duct 218, 219. Specifically, the conduit 220 is coupled to the annular duct 218 at the first end 208 of the compressor 200 and the conduit 221 is coupled to the annular duct 219 at the second end 210 of the compressor 200. The conduit 220, 221 may be fixedly coupled or removably coupled to the corresponding annular duct 218, 219, as per application requirements. The conduit 220, 221 may be coupled to the corresponding annular duct 218, 219 via one or more fastening elements or the conduit 220, 221 may be coupled to the corresponding annular duct 218, 219 via a threaded arrangement. In some examples, the fastening elements may include a bolt, a screw, a rivet, or the like. In other examples, the conduit 220, 221 may be coupled to the corresponding annular duct 218, 219 via welding, brazing, soldering, and the like.

Referring to FIG. 4, a schematic view of the sealing system 216 and a portion of the compressor 200 is illustrated. The sealing system 216 further includes a vacuum source 222. The vacuum source 222 is in fluid communication with the annular duct 218, 219 (see FIG. 2) via the conduit 220, 221. In some examples, the vacuum source 222 is a vacuum pump. The vacuum pump may include any conventional pump that can generate vacuum. In an operational state of the vacuum source 222, the vacuum source 222 generates a vacuum in the annular duct 218, 219 to direct gases leaking through the connection interface 214, 215 (see FIG. 2) in the annular duct 218, 219. Further, the vacuum source 222 may also be in fluid communication with other low pressure leakage sources (not shown) of the compressor 200. Accordingly, the vacuum generated by the vacuum source 222 may allow receipt of gases leaking through other low pressure leakage sources of the compressor 200. The vacuum source 222 may operate in the operational state when the compressor 200 is in operation.

Referring to FIG. 5, the sealing system 216 also includes a controller 224. The controller 224 controls an operation of the vacuum source 222 to maintain a predetermined amount of vacuum in the annular duct 218, 219 (see FIG. 2).

The sealing system 216 further includes a pressure sensor 226, 227 in fluid communication with the annular duct 218, 219, respectively. In the illustrated example of FIG. 5, the pressure sensor 226 is disposed in the annular duct 218 and the pressure sensor 227 is disposed in the annular duct 219. The pressure sensor 226, 227 determines a real-time pressure in the annular duct 218, 219, respectively. Specifically, the pressure sensor 226 determines the real-time pressure in the annular duct 218. The pressure sensor 227 determines the real-time pressure in the annular duct 219. In some examples, the pressure sensors 226, 227 may include a potentiometric pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, a piezoelectric pressure sensor, a strain gauge pressure sensor, or a variable reluctance pressure sensor. The present disclosure is not limited by a type of the pressure sensor 226, 227.

The controller 224 receives a value of the real-time pressure in the annular duct 218, 219 from the pressure sensor 226, 227. The controller 224 further controls the operation of the vacuum source 222 to maintain the predetermined amount of vacuum in the annular duct 218, 219 based on the value of the real-time pressure received from the pressure sensor 226, 227. In some examples, the controller 224 may compare the real-time pressure in the annular duct 218, 219 with a value of the predetermined amount of vacuum that is required to be maintained in the annular duct 218, 219. If the real-time pressure in the annular duct 218, 219 is less than the value of the predetermined amount of vacuum, the controller 224 may control the vacuum source 222 so that the real-time pressure corresponds to the value of the predetermined amount of vacuum.

The sealing system 216 also includes a gas detection sensor 228, 229 in fluid communication with the annular duct 218, 219, respectively. In the illustrated example of FIG. 5, the gas detection sensor 228 is disposed in the annular duct 218 and the gas detection sensor 229 is disposed in the annular duct 219. The gas detection sensor 228, 229 determines a presence of gas in the annular duct 218, 219, respectively. In some examples, the gas detection sensors 228, 229 may include an electrochemical sensor, a catalytic sensor, an infrared sensor or a photoionization sensor. The present disclosure is not limited by a type of the gas detection sensor 228, 229.

The controller 224 receives an indication of the presence of gas in the annular duct 218, 219 from the gas detection sensor 228, 229. The controller 224 further controls the operation of the vacuum source 222 based on the presence of gas detected by the gas detection sensor 228, 229. In some examples, the gas detection sensor 228, 229 may detect a volume/a concentration of gas within the in the annular duct 218, 219. In such examples, if the controller 224 determines an increased volume of gases in the annular duct 218, 219, the controller 224 may operate the vacuum source 222 at an increased rate to handle the increased volume of gases.

The controller 224 may be a control circuit, a computer, a microprocessor, a microcomputer, a central processing unit, or any suitable device or apparatus. The controller 224 may include one or more memories and one or more processors. The one or more processors may be communicably coupled with the one or more memories. The one or more memories may store the value of the predetermined amount of vacuum therein. In some examples, an operator of the compressor 200 may have remote access to the controller 224 to control an operation of the sealing system 216. For example, the operator may provide manual inputs to the controller 224 to operate the vacuum source 222 at a desired rate and/or configuration.

Referring again to FIG. 4, the sealing system 216 further includes a collection chamber 230 that is in fluid communication with the annular duct 218, 219 (see FIG. 2) via the conduit 220, 221. Specifically, the collection chamber 230 is in fluid communication with the annular duct 218 via the conduit 220. The collection chamber 230 is in fluid communication with the annular duct 219 via the conduit 221. When the vacuum source 222 is in the operational state, the gases collected in the annular duct 218, 219 are further directed towards the collecting chamber 230. The collecting chamber 230 may collect and store the gases.

In some examples, the collection chamber 230 may recirculate the gases back into the compressor 200 (see FIG. 1) via the suction port 204 (see FIG. 1). In an example, the gases collected in the collection chamber 230 may be used for analysis to determine one or more characteristics of the gases. In another example, the collection chamber 230 may be in fluid communication with a flare system (not shown). In such an example, the gases collected in the collection chamber 230 may be directed towards the flare system.

It is to be understood that individual features shown or described for one embodiment may be combined with individual features shown or described for another embodiment. The above described implementation does not in any way limit the scope of the present disclosure. Therefore, it is to be understood although some features are shown or described to illustrate the use of the present disclosure in the context of functional segments, such features may be omitted from the scope of the present disclosure without departing from the spirit of the present disclosure as defined in the appended claims.
