Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing auxiliary gas coolers in the compressor field, and in particular to a gas cooling test and cleaning device and a control method. Background Art

[0002] Compressors are at the heart of the chemical industry, and gas coolers are key auxiliary components of compressors. They cool the substantial heat generated by gas compression in the compressor, ensuring that the gas can flow within the system within a reasonable temperature range. Therefore, the actual cooling effect of a gas cooler significantly impacts the operating efficiency of a compressor. Furthermore, compressors require a very clean working environment for the gas. For example, the gas cooler used in an oxygen compressor operates in an oxygen-rich environment, posing a significant safety hazard from contact with oil stains. Therefore, the cleanliness of the gas side of the gas cooler must be guaranteed.

[0003] Existing compressor auxiliary gas coolers have similar shells, and their tube bundles are roughly divided into two types: one type uses composite heat exchange tubes, which guarantees heat transfer efficiency but is expensive; the other type combines heat exchange tubes with large fins, which is cheaper than the composite heat exchange tube bundle. However, the heat transfer efficiency is positively correlated with the manufacturing process, making the gas cooler's heat transfer efficiency uncertain. Currently, most manufacturers of compressor auxiliary gas coolers use the first type of tube bundle to ensure the heat transfer efficiency of the second type, which results in higher manufacturing costs. Summary of the Invention

[0004] Therefore, the technical problem to be solved by this application is to provide a gas cooling test and cleaning device and control method, which can confirm whether the gas cooling device meets the heat exchange requirements under the conditions of use, while ensuring the cleanliness of the inner surface of the gas cooling device.

[0005] In order to solve the above problems, the present application provides a gas cooling test and cleaning device for use in compressor equipment, comprising: a gas heating device, a connecting component, a gas cooling device, and a cleaning device;

[0006] The connecting component integrates a thermocouple and a pressure acquisition device;

[0007] One end of the gas heating device is connected to the compressor, and the other end of the gas heating device is connected to the air inlet of the gas cooling device through a first pipe;

[0008] The air outlet of the gas cooling device is connected to the air inlet of the cleaning device through the connecting component.

[0009] Furthermore, the connecting component also includes a reducing flange and a second pipe; one end of the reducing flange is adapted to the outer diameter of the second pipe, and the other end is adapted to the flange interface of the air inlet of the cleaning device.

[0010] Furthermore, two ends of the first pipe are fixedly connected to a first flange and a second flange respectively;

[0011] The first flange is provided at one end of the first pipeline close to the gas heating device, and is used to be connected to the output end flange of the gas heating device. The second flange is located at one end of the first pipeline close to the gas cooling device, and is fastened to the flange interface at the air inlet of the gas cooling device.

[0012] Furthermore, the connecting component is provided with threaded holes respectively adapted to the thermocouple and the pressure collection device.

[0013] Furthermore, an exhaust valve is provided between the connecting component and the air outlet of the first pipeline.

[0014] Furthermore, clamps are respectively provided at the connection points between the first pipe, the first flange and the second flange for fixing the first pipe.

[0015] Furthermore, a control method for a gas cooling and cleaning device is provided, and the control method is implemented based on the gas cooling test and cleaning device described above.

[0016] Furthermore, the control method includes: S1, starting the compressor device and the gas heating device, opening the exhaust valve, and transporting the gas passing through the gas heating device to the gas cooling device through the first pipeline;

[0017] S2. Obtaining a temperature curve of the gas cooling device within a first set time period through a thermocouple, and determining whether a set test temperature A of the gas cooling device is reached based on the temperature curve;

[0018] If the set test temperature A1 of the gas cooling device is reached at the first moment, the exhaust valve of the gas outlet is closed;

[0019] S3. By comparing the pressure value P of the pressure acquisition device at the first moment with the set test pressure value P1, it is determined whether the set test pressure value P1 of the gas cooling device is reached at the first moment. If so, the exhaust valve of the air outlet is opened, and the temperature value B of the air outlet of the gas cooling device within the second set time period is obtained and recorded through a thermocouple.

[0020] Furthermore, the control method further includes: S4, judging the heat exchange effect of the gas cooling device by comparing the temperature value B of the gas outlet of the gas cooling device within the second set time period with the set temperature curve value B1;

[0021] If the temperature value B at the gas outlet of the gas cooling device within the second set time period is less than or equal to the set temperature curve value B1, the heat exchange effect of the gas cooling device meets the test requirements;

[0022] If the temperature value B at the gas outlet of the gas cooling device within the second set time period is greater than the set temperature curve value B1, the heat exchange effect of the gas cooling device does not meet the test requirements.

[0023] Furthermore, the control method further includes: S5, after determining the heat exchange effect of the gas cooling device, starting the cleaning device, and the gas cooled by the gas cooling device enters the cleaning device through the connecting component to remove pollutants in the gas.

[0036] In a feasible embodiment, the connecting component 5 further includes a reducing flange 51 and a second pipe 52; one end of the reducing flange 51 is adapted to the outer diameter of the second pipe 52, and the other end is adapted to the flange interface of the air inlet of the cleaning device 6.

[0037] Specifically, the connecting component 5 in the present application is one of the core components of the device, which innovatively integrates the reducing flange 51. This design enables the device to be easily adapted to pipes of various specifications, greatly improving the flexibility and versatility of the system. One end of the reducing flange 51 is precisely adapted to the outer diameter of the second pipe 52, and the other end is perfectly matched with the flange interface of the air inlet of the cleaning device 6, ensuring smooth gas circulation and the stability of the connection. In addition, threaded holes adapted to the thermocouple 7 and the pressure acquisition device 11 are cleverly provided on the reducing flange 51. The ends of the thermocouple 7 and the pressure acquisition device 11 are equipped with corresponding threads, and sealing tape is wrapped around the threads to ensure a tight connection with the reducing flange 51, effectively preventing gas leakage, and ensuring the accuracy of the measurement and the safety of the system.

[0038] In this embodiment, the first pipe 3 is fixedly connected to a first flange 31 and a second flange 32 at both ends. The first flange 31 is located at the end of the first pipe 3 near the gas heating device 2 and is flange-connected to the output end of the gas heating device 2. The second flange 32 is located at the end of the first pipe 3 near the gas cooling device 4 and is fastened to the flange interface at the gas inlet 41 of the gas cooling device 4. Clamps are provided at the connection between the first pipe 3 and the first flange 31 and the second flange 32, respectively, for securing the first pipe 3.

[0039] In this embodiment, the first pipe 3 is configured as a metal braided hose; specifically, the first pipe 3 is fixed using a special welding fixture to ensure the rigidity of the welding positions on both sides of the first pipe 3, and the first flange 31 and the second flange 32 are respectively placed on both sides of the first pipe 3 and spot welded. The first pipe 3 adopts the design of a metal braided hose. This hose not only has good flexibility and corrosion resistance, but can also withstand high pressure and temperature. During the manufacturing process, a special welding fixture is used to fix the hose to ensure the rigidity of the welding positions on both sides. Subsequently, the first flange 31 and the second flange 32 are respectively placed on both sides of the hose and firmly connected by spot welding technology.

The compressor 1 and gas heating device 2 are then started, and high-temperature gas is injected into the gas cooling device 4 through the first pipe 3 and the connecting component 5. The temperature displayed by the thermocouple 7 on the connecting component 5 at the air inlet is obtained. When the temperature of the inlet thermocouple 7 reaches the operating temperature of the gas cooling device 4, the outlet vent valve 12 is closed. After the pressure acquisition device 11 displays the operating pressure, the outlet vent valve is opened, the temperature displayed by the outlet thermocouple 9 is checked, and the temperature parameter curve is recorded. After the equipment operating test procedure is completed, the compressor 1 and gas heating device 2 are shut down, and the high-temperature, high-pressure gas in the gas cooling device 4 is discharged into the cleaning device 6. During the test, the high-temperature, high-pressure gas in the gas cooling device 4 evaporates any residual water stains and difficult-to-remove grease in the gas cooling device 4 after water pressure is applied, dissolving into the high-temperature gas. After the test, it is discharged from the equipment along with the gas, significantly improving the cleanliness of the gas side of the gas cooler. Moreover, the present application greatly ensures the heat exchange capacity of the heat exchange tubes of the gas cooler and the large-fin composite tube bundle, promotes the development of such tube bundles, and indirectly reduces the equipment manufacturing cost.
