[0002] A centrifugal compressor is a type of turbine compressor that features large gas handling capacity, small size, simple structure, stable operation, easy maintenance, and gas free from oil contamination. Its working process can be divided into the following steps:

[0003] a. Centrifugal air is sent to the rotating centrifugal wheel at the inlet and is rotated rapidly.

[0004] b. The rotation of the centrifugal wheel squeezes the air, increasing its pressure and temperature.

[0005] c. The compressed gas is sent to the cooler, which reduces the temperature of the gas before sending it to the storage tank and then to the next process for use.

[0006] Among them, the cooler plays a very important role in the entire workflow.

[0007] One type of cooler for a centrifugal air compressor is a water cooler, and its working principle is as follows: the compressed high-pressure and high-temperature gas is cooled by flowing water, and the flow of water is used to exchange the heat of the high-pressure and high-temperature gas through the cooler, and the heat is transferred to the water to cool the high-temperature and high-pressure airflow of the air compressor; the patent with publication number CN116877494A discloses an anti-clogging cooler for a centrifugal air compressor, but its water inlet, water outlet, air inlet pipe, and air outlet pipe are not arranged on the same side, that is, when the cooler is used, the connection space of the water inlet, water outlet, air inlet pipe, and air outlet pipe also needs to be considered, the space occupancy rate is relatively large, and its heat exchange mechanism adopts a non-detachable design or a design that is difficult to disassemble, which makes later maintenance difficult.

DETAILED DESCRIPTION

[0025] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0026] In this utility model, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 For example, the positional relationships of front, back, up, down, left, and right are determined according to the layout directions of the drawings in the specification.

[0027] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0028] As attached Figure 1 、 2As shown, the air compressor cooler includes a shell 1, a connecting plate 2, and a tail plate 3. The shell 1 is a cylindrical shell that is through-through. The tail plate 3 and the connecting plate 2 are respectively installed at both ends of the shell 1. A cooling tower 4 is installed on the connecting plate 2, and the left side of the cooling tower 4 is provided with an air passage 43 that is through-through inside and outside. Heat dissipation fins 10 are distributed at intervals in the cooling tower 4. An inlet pipe 5 and an outlet pipe 6 are provided at the right end of the cooling tower 4. A water distribution box 71 and a return water box 81 are respectively provided on the inside of the right side of the cooling tower 4 corresponding to the positions of the inlet pipe 5 and the outlet pipe. A return box 11 is provided on the inside of the left side of the cooling tower 4. An inlet pipe 72 and a return pipe 6 are provided in the cooling tower 4. 82, the water inlet pipe 5 is connected to the water distribution box 71, the water distribution box 71 is connected to the inlet end of the water inlet tube 72, the water outlet pipe 6 is connected to the return water box 82, the outlet end of the return water tube 82 is connected to the return water box 81, the outlet end of the water inlet tube 72 and the inlet end of the return water tube 82 pass through the heat dissipation fins 10 and are respectively connected to the return box 11, an air inlet pipe 12 and an air outlet pipe 13 are provided on the connecting plate 2, and a sealing strip 9 is provided around the outer periphery of the left part of the cooling tower 4, which is sealed with the outer shell 1 and the tail plate 3. The sealing strip 9 divides the space in the outer shell 1 into two upper and lower spaces. Of the two spaces, the one connected to the air inlet pipe 12 is a hot air bin 14, and the one connected to the air outlet pipe 13 is a cold air bin 15.

[0029] When in use, a pipe is used to connect the air inlet pipe 12 and the compressed air port of the air compressor, a pipe is used to connect the air outlet pipe 13 and the air-using equipment, the water inlet valve 51 is connected to the outlet of the cooling water circulation water circuit, and the water outlet pipe 6 is connected to the return water port of the cooling water circulation water circuit.

[0030] When the air compressor is working, the high-pressure and high-temperature air flow enters the hot air bin 14 from the air inlet pipe 12. Because the cooling tower 4 is sealed with sealing strips 9 and the outer shell 1 and the tail plate 3 on all sides, the high-pressure and high-temperature air flow in the hot air bin 14 can only enter the interior of the cooling tower 4 from the air passage 43, and pass through the gap between each group of heat dissipation fins 10, and form heat exchange with each group of heat dissipation fins 10; at the same time, the water inlet pipe 5 is opened, and the cooling water enters the water distribution box 71. The water distribution box 71 divides the cooling water to each group of water inlet tubes 72, and then flows from the water inlet tubes 72 to the return box 11. The return box 11 then divides the cooling water to each group of return water tubes 82. The heat dissipation fins 10 arrayed on the water inlet tubes 72 and the return water tubes 82 form heat exchange with the high-temperature and high-temperature air flow, thereby cooling the high-pressure and high-temperature air flow.

[0031] The cooled high-pressure airflow enters the cold air chamber 15 from the air passage 43, and is discharged from the air outlet pipe 13 connected to the cold air chamber 15 and delivered to the gas-consuming equipment. The hot water after cooling the high-temperature airflow will be transported to the return water box 81 by the water outlet circuit 8 for collection, and the hot water will be delivered to the return water outlet of the cooling water circulation waterway through the water outlet pipe 6 connected to the return water box 81.

[0032] The utility model arranges the water inlet pipe 5, the water outlet pipe 6, the air inlet pipe 12 and the air outlet pipe 13 on one side of the connecting plate, which saves installation space. Through the establishment of the sealing strip 9, the cooling tower 4 and the shell 1 are softly connected. The bolts or buckles on the connecting plate 2 can be loosened, and the connecting plate 2 and the cooling tower 4 can be pulled out of the shell 1 as a whole. The cooling tower can be directly inspected and maintained, and the disassembly and maintenance are convenient.

[0033] The above-mentioned air compressor cooler can be further optimized and / or improved according to actual needs:

[0034] As attached Figure 1 、 2 As shown, the sealing strip is a Y-shaped rubber strip. The sealing strip 9 includes a connecting portion 91 and a V-shaped elastic pressing portion 92. The inner end of the elastic pressing portion 92 is integrally provided with the outer end of the connecting portion 91. The tail sealing block 32 is fixed to the inner side of the tail plate 3 by a connecting bolt 31. The outer side of the elastic pressing portion 92 on the inner side of the tail sealing block 32 is in shape consistent with that of the elastic pressing portion 92. The outer end of the elastic pressing portion 92 is sealed with the tail sealing block 32 and the inner side of the housing 1.

[0035] When the high-temperature and high-pressure airflow pushes the sealing strip 9, because the elastic pressing portion 92 of the sealing strip 9 is pressed and connected to the inner wall of the outer shell 1, the sealing strip 9 has a Y-shaped structure. Therefore, when the high-temperature and high-pressure airflow pushes the sealing strip 9, the elastic pressing portion 92 on the sealing strip 9 will have a tendency to move closer, and then the elastic pressing portion 92 on the hot air bin 14 side will be closer to the inner wall of the outer shell 1, further increasing the air tightness of the connection. The greater the air pressure in the air inlet pipe 12, the better the sealing effect of the sealing strip 9 will be.

[0036] As attached Figure 1 、 2 As shown, a semi-open ring-shaped clamping ring 41 is provided around the left periphery of the cooling tower 4. The clamping ring 41 clamps the connecting portion 91 of the sealing strip 9 and is fixed with bolts. The connecting portion 91 elastically expands and is embedded in the gap of the clamping ring 41 in an interference fit manner. The clamping ring 41 is a quick-connect structure, which facilitates the removal of the sealing strip.

[0037] As attached Figure 1 、 2 As shown, the upper and lower sides of the cooling tower 4 are provided with supports 42 that can keep the cooling tower 4 centered. The supports 42 keep the cooling tower 4 centered and keep the space allocation of the hot gas bin 14 and the cold gas bin 15 unchanged.

[0038] The inner side of the shell corresponding to the position of the support frame 42 is provided with a chute 16 that can embed the support frame 42. By providing the chute 16, the cooling tower 4 can be disassembled or installed by pulling.

[0039] The water inlet pipe 5 is provided with a water inlet valve 51. The cooling water switch and the water flow size are controlled by setting the water inlet valve 51.

[0040] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
