Abstract

The invention relates to an interstage cooling system of a water-saving compressor. The interstage cooling system comprises a compressor preceding stage (1), an interstage cooler (2), a compressor backward stage (4), a first cooling pump (5) and a water cooling tower (3), and a cooling coil (2-1) is arranged on the interstage cooler (2). The interstage cooling system of the water-saving compressor is characterized in that an air cooling tower (6) and corresponding second cooling water pump (9) are added to the system; the cooling coil (2-1) is partitioned into a high-temperature zone (A) and a low-temperature zone (B); a cooling water pipeline of the high-temperature zone (A) is connected with the air cooling tower (6); the cooling water pipeline of the low-temperature zone (B) is connected with the water cooling tower; and compressed air discharged from the compressor preceding stage (1) firstly passes through the high-temperature zone (A) of the cooling coil (2-1) and then enters the low-temperature zone (B) after entering the interstage cooler (2). The interstage cooling system of the water-saving compressor has the advantages that water resources can be saved.

Example Embodiment

[0029] Example 1:
[0030] See figure 2 , figure 2 Schematic diagram of Example 1 for implementing the present invention. by figure 2 It can be seen that the water-saving compressor inter-stage cooling system of the present invention is composed of a compressor front stage 1, an inter-stage cooler 2, a compressor rear stage 4, a first cooling water pump 5, a water cooling tower 3, and the like. Cooling coil 2-1 is set in 2 of the interstage cooler, and figure 1 The difference in the prior art shown is that this embodiment 1 divides the cooling coil 2-1 in the inter-stage cooler 2 into two parts, a high temperature zone A and a low temperature zone B, and an air cooling tower 6 is added to the system. With the corresponding second cooling water pump 9, the cooling water pipe in the high temperature zone A is connected to the air cooling tower 6, and the cooling water pipe in the low temperature zone B is connected to the water cooling tower; the cooling water in the high temperature zone A is cooled by the air cooling tower 6, The cooling water in the low temperature zone B is cooled by the water cooling tower 3. After the compressed air discharged from the compressor front stage 1 enters the interstage cooler 2, it is first cooled by the high temperature zone A of the cooling coil 2, and then enters the low temperature zone B for cooling. The cooled compressed air is discharged from the interstage cooler 2. After entering the compressor, stage 4 is further compressed.
[0031] When the ambient temperature is high, two sets of cooling water, namely the higher temperature cooling water circulating between the high temperature zone A and the air cooling tower 6 and the lower temperature circulating between the low temperature zone B and the water cooling tower 3 The cooling water circulates at the same time and continuously discharges the heat in the compressed air through the air cooling tower 6 and the water cooling tower 3. When the ambient temperature is low, only the cooling water between the high temperature zone A and the air cooling tower 6 circulates, and the air cooling tower 6 works normally; the other group of cooling water stops, and the water cooling tower is also out of service; because of the air cooling at this time The temperature of the outlet water of the tower 6 is also relatively low, and only the high temperature zone A group operation can meet the cooling requirements.

Example Embodiment

[0032] Example 2:
[0033] See image 3 , Example 2 is based on Example 1, connecting the outlet pipe of the second cooling water pump 9 corresponding to the air cooling tower 6 with the inlet pipe of the low temperature zone B of the cooling coil 2-1, connecting the low temperature zone B The outlet pipe is connected with the inlet pipe of the high temperature zone A, and the first switching valve 7 (total 3 pieces) and the second switching valve 8 (2 pieces) are added, and the first switching valve 7 and the second switching valve 8 are opened to make the high temperature zone The cooling water of A and low temperature zone B is cooled in the air cooling tower 6 and the water cooling tower 3 respectively, or the first switching valve 7 is closed and the second switching valve 8 is opened to connect the cooling water of the low temperature zone B and the high temperature zone A in series The method is cooled in the air cooling tower 6 and enters the low temperature zone B first and then enters the high temperature zone A.

Example Embodiment

[0034] Example 3:
[0035] See Figure 4 , Example 3 is based on Example 1, the return pipe of the air cooling tower 6 and the corresponding outlet pipe of the second cooling water pump 9 are respectively connected to the outlet pipe and inlet pipe of the low temperature zone B of the cooling coil 2-1 Connect and add the first switching valve 7 (2 in total) and the second switching valve 8 (2) in the system pipeline, open the first switching valve 7 and close the second switching valve 8 to make the high temperature zone A and the low temperature zone The cooling water of B is cooled in the air cooling tower 6 and the water cooling tower 3, or the first switching valve 7 is closed and the second switching valve 8 is opened, so that the cooling water in the low temperature zone B and the high temperature zone A is cooled in the air in parallel Cooling in tower 6.
