Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a cooling device for an air compressor in a waste treatment plant. Background Technology

[0002] In waste treatment, air compressors need to operate 24 hours a day. These compressors require cooling water; however, existing cooling water supplies often fail to meet the compressor's water pressure requirements, leading to compressor shutdowns due to excessively high oil temperatures. Typically, an oil cooler is added to lower the oil temperature and compensate for insufficient cooling water pressure, but this reduces the compressor's heat exchange efficiency. However, in existing oil coolers, oil enters the cooling body through the oil inlet. Due to the oil's thickness, the oil flow rate within the cooling body is often too fast, resulting in insufficient cooling and reduced cooling efficiency. Therefore, this invention proposes a cooling device for air compressors in waste treatment plants to improve oil cooling efficiency. Utility Model Content

[0021] See Figures 1-5 This embodiment provides a cooling device for an air compressor in a waste treatment plant, including an air compressor oil tank 1, an oil cooler 5, and a water cooler 7.

[0022] The oil cooler 5 includes a cooling oil pipe body 50, an end cap 51, and an end cap 52. The end cap 51 and the end cap 52 are respectively bolted to the top and bottom of the cooling oil pipe body 50. The cooling oil pipe body 50 has multiple heat exchange tubes 56 inside, and the two ends of the multiple heat exchange tubes 56 are respectively connected to the two ends of the cooling oil pipe body 50. The tube walls of the heat exchange tubes 56 are evenly provided with multiple heat exchange plates 560 to improve heat exchange efficiency. The end cap 52 is provided with a partition 53, which divides the end cap 52 into two parts, and connects to an inlet pipe 6 and an outlet pipe 9 respectively. The partition 53, the end cap 51, and the end cap 52 are all tightly connected to the cooling oil pipe body 50 through sealing gaskets. The side wall of the oil cooling pipe body 50 is provided with an oil inlet pipe 2 and an oil outlet pipe 10. A precooler 4 is provided on the oil inlet pipe 2 and the oil outlet pipe 10. The precooler 4 includes a ceramic heat dissipation pipe 40 sleeved on the outer wall of the oil inlet pipe 2 or the oil outlet pipe 10. A heat dissipation cylinder 41 is sleeved on the outer wall of the ceramic heat dissipation pipe 40. A plurality of heat dissipation plates 42 are evenly arranged on the outer wall of the heat dissipation cylinder 41. The heat dissipation cylinder 41 and the heat dissipation plates 42 are made of aluminum. Two of the heat dissipation plates 42 are symmetrical about the top and bottom, and a fixing plate 43 is provided at the bottom of them. The outer end of the fixing plate 43 is provided with a fixing hole 430. The heat dissipation cylinder 41 is fixed to the oil cooler 5 by bolts through the fixing hole 430.

[0023] In this embodiment, the chiller 7 includes a heat dissipation chamber 71 and a cold water chamber 70 arranged from top to bottom. A connecting pipe 77 and a water supply pipe 78 are respectively provided on both sides of the bottom of the cold water chamber 70. Multiple cooling fins 75 are spaced apart on the top of the cold water chamber 70. A cooler 72 is provided at the bottom of the heat dissipation chamber 71. Mounting holes 76 and ventilation holes 74 are respectively provided on both sides of the heat dissipation chamber 71. A fan 73 is installed in the mounting hole 76. The cooling surface of the cooler 72 is in close contact with the top of the water tank, and together with the cooling fins, lowers the water temperature in the cold water chamber 70. The fan 73 and ventilation holes 74 work together to quickly dissipate heat from the heating surface of the cooler 72, improving the cooling efficiency of the cooler.

[0024] In this embodiment, the water supply pipe 78 of the water cooler 7 is connected to the water inlet 6 of the oil cooler 5, the oil inlet pipe 3 of the oil cooler 5 is connected to the output pipe of the air compressor oil tank 1, the oil outlet pipe 10 of the oil cooler is connected to the input pipe 12 of the air compressor oil tank 1, and an oil pump is installed on the input pipe 12.

[0025] Preferably, the surface of the oil cooler 5 is uniformly distributed with recesses 54, and the bottom of the recesses is provided with protrusions 55;

[0026] In practical implementation, the oil in the air compressor oil tank 1, under the action of the oil pump 11, enters the oil cooler 5, is cooled by the heat exchange tube 56, and then returns to the air compressor oil tank 1. External water enters the chiller through a connecting pipe, is cooled, and then flows through the inlet pipe 6 to one side of end cover 52, through the heat exchange tube 56 to end cover 51, and then through the heat exchange tube to the other side of end cover 52, before being output through the outlet pipe 9, thus cooling the oil. As the oil passes through the inlet pipe 3 and outlet pipe 10, the precooler 4 cools the oil in the inlet and outlet pipes, improving cooling efficiency. The water temperature decreases as it passes through the chiller, further improving the oil cooling efficiency. The concave and convex features on the surface of the oil cooling pipe body 50 increase the heat dissipation area, further improving the oil cooling efficiency.
