BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0014] Figure 1 It is a schematic diagram of the working structure of an embodiment of the utility model.

[0015] In the above drawings: sewage pool 1, cold water pump 2, return pipe 3, fan 4, heat exchanger 5, air outlet pipe 6, air inlet pipe 7, air outlet 8, air inlet 9, temperature sensor 10, frequency conversion control cabinet 11, filter 12, distribution room 13. DETAILED DESCRIPTION

[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, the embodiment of the utility model proposes a cooling device for the power distribution room of a municipal sewage treatment plant, comprising a sewage pool 1 filled with treated sewage, a cold water pump 2, a return pipe 3, a fan 4, a heat exchanger 5, an air outlet pipe 6 and an air inlet pipe 7, wherein the cold water pump 2 is installed on the return pipe 3 for pumping the sewage in the sewage pool 1, the heat exchanger 5 is installed on the return pipe 3, the fan 4 is installed on the heat exchanger 5 and connected to the air outlet pipe 6 for pumping the wind for heat exchange of the heat exchanger 5, the air inlet pipe 7 is communicated with the heat exchanger 5, and the air outlet 8 of the air outlet pipe 6 and the air inlet 9 of the air inlet pipe 7 are installed in the power distribution room 13.

[0018] like Figure 1 As shown, the treated sewage in the urban sewage treatment plant has a temperature of about 15-20° in summer. It is pressurized and lifted to the heat exchanger 5 by the cold water pump 2, and the distribution room 13 is exhausted by the fan 4. The hot air in the distribution room 13 is heat exchanged through the heat exchanger 5, and the cooled cold air is sent to the distribution room 13 by the fan 4. The sewage in the return pipe 3 is heated by heat exchange and then returned to the sewage pool 1 to complete the cooling of the distribution room 13. The heat exchange tubes of the heat exchanger 5 can adopt coil-type copper heat exchange tubes to increase the heat exchange efficiency.

[0019] In order to facilitate control, Figure 1 As shown, a temperature sensor 10 is installed in the heat exchanger 5 for detecting the air temperature in the heat exchanger 5. In order to ensure the temperature balance of the distribution room 13, a temperature sensor 10 is set at the air inlet 9 and the air outlet 8 of the heat exchanger 5 to monitor the supply air temperature and the return air temperature of the distribution room 13.

[0020] In this embodiment, the cold water pump 2 is connected to a frequency conversion control cabinet 11. When the temperature of the power distribution room 13 is too high or too low, the frequency conversion control cabinet 11 of the cold water pump 2 controls the amount of cold water to achieve constant temperature control of the power distribution room 13.

[0021] Considering the cooling effect, in order to evenly cool the power distribution room 13, the air outlet 8 of the air outlet duct 6 and the air inlet 9 of the air inlet duct 7 are provided in multiple numbers and evenly distributed on the top surface of the power distribution room 13. The cold air descends from the air outlet 8 of the air outlet duct 6 to the lower layer of the power distribution room 13, and the hot air in the upper layer is drawn away from the air inlet 9 of the air inlet duct 7, so as to achieve cooling of the power distribution room 13.

[0022] In this embodiment, the air outlet 8 of the air outlet pipe 6 and the air inlet 9 of the air inlet pipe 7 are staggered so as to quickly and evenly cool the power distribution room 13 .

[0023] In order to prevent the return pipe 3 from being blocked, a filter screen 12 is fixedly installed on the inner wall of the sewage pool 1 , and the filter screen 12 is located at the water inlet of the return pipe 3 .

[0024] In addition to being used for cooling the power distribution room 13, it can also be used for cooling the office building in summer.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
