The counter-convective heat exchange design between sewage and compressed air efficiently transfers heat from the sewage, significantly improving heat exchange efficiency.

Description

Technical Field

[0001] This utility model belongs to the technical field of sewage cooling equipment, and specifically relates to a sewage cooling equipment. Background Technology

[0002] Wastewater cooling equipment is a specialized device used to reduce the temperature of wastewater. It primarily works by transferring heat from the wastewater to a cooling medium through heat exchange, thereby cooling the wastewater. Its core function is to control the wastewater temperature within a suitable range to meet the requirements of subsequent treatment processes.

[0003] Existing wastewater cooling equipment uses an inefficient heat exchange structure, resulting in insufficient cooling in a single cycle, requiring multiple cycles to achieve the desired cooling effect. Furthermore, the cooling efficiency is low, and the cooling effect is easily reduced due to the accumulation of impurities. Therefore, a wastewater cooling equipment is needed to solve these problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater cooling device, comprising a mounting base, a first connecting bolt, and a second connecting bolt. Four mounting bolts are inserted and connected inside the mounting base. A support plate is fixedly connected to the top of the mounting base. An aeration fan is fixedly connected to the top of the support plate. A heat exchanger is fixedly connected to one end of the aeration fan. A first flange is fixedly connected to one end of the heat exchanger. A second flange is fixedly connected to one side surface of the first flange.

Combined with the counter-convective heat exchange design between sewage and compressed air, the heat of sewage can be efficiently transferred, significantly improving the heat exchange efficiency. At the same time, the sewage pump can promptly discharge deposited impurities in the annular flow channel, preventing impurities from affecting the heat exchange effect and ensuring the continuous and stable operation of the equipment.

[0008] As a preferred embodiment, the first connecting bolt is inserted into and connected to the second flange.

[0010] As a preferred embodiment, the second connecting bolt is inserted into and connected to the third flange.

[0011] As a preferred embodiment, the second connecting bolt is inserted into and connected to the fourth flange.

[0012] By setting up a sealed air passage, the first flange and the second flange are connected by a combination of first connecting bolts, which can achieve a sealed connection of the compressed air passage and prevent gas leakage. The third flange and the fourth flange are connected by second connecting bolts, which can ensure the stable installation of the air outlet and the smooth outflow of air, forming a complete compressed air low-temperature inlet and high-temperature outlet passage.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

By setting up the outer sewage pipe 10 and the spiral guide inner pipe 9, a ring-shaped flow channel is formed by the outer sewage pipe 10 and the spiral guide inner pipe 9.

[0028] Working principle and usage process of this utility model:

[0029] The aeration blower 4 is fixed to the mounting base 1 by the mounting bolts 2. When the aeration blower 4 is started, the compressed air output by it is first pre-cooled by the heat exchanger 5. The pre-cooled compressed air enters the spiral guide inner pipe 9 through the connection of the first flange 6 and the second flange 7. At the same time, sewage flows from the sewage inlet pipe 16 into the sewage outlet pipe 10 sleeved outside the spiral guide inner pipe 9. The compressed air and sewage flow in opposite directions in the annular space formed by the spiral guide inner pipe 9 and the sewage outlet pipe 10. The heat exchange is enhanced by the heat dissipation fins 15 on the surface of the spiral guide inner pipe 9, so that the heat of the sewage is transferred to the compressed air. After the sewage is cooled, it is discharged from the sewage outlet pipe 18. The compressed air absorbs heat and is heated up before being discharged through the air outlet 14. During the process, the temperature is monitored by the first thermometer 17 and the second thermometer 19. The sewage pump 21 connected to the bottom sewage pipe 20 can periodically discharge the deposited impurities to ensure the stable operation of the equipment.
