[0018] Reference Figures 1 to 3 An air pollution monitoring device with self-cleaning function includes an equipment box 23. A first partition 6 and a second partition 16 are fixedly installed inside the equipment box 23. The second partition 16 is located below the first partition 6. A flow meter 7 is fixedly installed above the first partition 6. A sensor 8 is fixedly installed above the flow meter 7. A flow stabilizing valve 5 is provided behind the flow meter 7. The flow stabilizing valve 5 is fixedly installed on the first partition 6. A first relay 12 is fixedly installed above the sensor 8.

[0020] The drying tube 1 is connected to the molecular sieve 3 and the second air filter 14 at the end through different gas conduits 4. The molecular sieve 3 is placed vertically and is connected to the first air filter 2 through the gas conduit 4. The first air filter 2 and the second air filter 2 are both located below the drying tube 1. The second air filter 2 is connected to the air pump 13 through a line.

[0021] An oil mist filter 11 is installed above the flow meter 7. The oil mist filter 11 is connected to the drying tube 1 through the gas conduit 4, and a wire groove 10 is provided on the side of the drying tube 1.

[0022] Among them, the gateway device 15 is fixedly installed above the second partition 16 by metal fasteners. The gateway device 15 is connected to the first switching power supply 20 by a line on its side. The first switching power supply 20 is connected to the cooling device 19 by a line. The cooling device 19 is located below the second partition 16, and there are two cooling devices 19.

[0023] The equipment box 17 is fixedly installed below the refrigeration equipment 19, and the equipment box 17 is fixedly installed inside the bottom of the equipment box 23. A second relay 18 is fixedly installed on the side of the equipment box 17, and the second relay 18 is connected to the refrigeration equipment 19 through a circuit.

[0026] This utility model is an air pollution monitoring device with self-cleaning function.

Subsequently, the air is split into two, one of which is used for monitoring and the other is used for self-cleaning.

[0027] In the monitoring route, the air after removing moisture enters the second air filter 14 to remove impurities. Then the air passes through the flow control valve 5, which controls the air flow rate. The air flow rate is displayed on the flow meter 7. The air then passes through the sensor 8. The air content and concentration data detected by the sensor 8 are used for index calculation through the gateway device 15. Finally, the air is discharged from the equipment.
