[0034] Referring to Figure 6 As shown in the figure, pump 17 is installed on the top of box 1, and the output end of pump 17 is fixedly connected with gas conveying pipe 18, so that the inside of hopper 11 is pressurized by pump 17 through gas conveying pipe 18, and strong pressure is generated in the airtight space formed by connecting frame 13 and second liquid outlet pipe 16.

[0035] Referring to Figure 1 And Figure 2As shown, the auxiliary cleaning mechanism on the upper surface of the box body 1 includes two double-headed motors 19, the bottom of the double-headed motor 19 is fixedly connected to the upper surface of the box body 1, and the two output ends of the double-headed motor 19 are fixedly connected to the first bevel gear 20, the bottom of the first bevel gear 20 is meshed with the second bevel gear 21, the interior of the second bevel gear 21 is fixedly connected with a threaded rod 22, and the outer sides of the multiple threaded rods 22 are threadedly connected to a cleaning frame 23, and the multiple threaded rods 22 are symmetrically distributed inside the cleaning frame 23.

[0036] Reference Figure 1 As shown, one side of the box body 1 is connected to an air inlet pipe 24 , and the other side of the box body 1 is connected to an air outlet pipe 25 .

[0037] The working principle of the present invention is as follows: when the waste gas is subjected to biological trickling filtration treatment, the waste gas is first passed from the air inlet pipe 24 into the interior of the box body 1, and then the nutrient solution is passed from the liquid inlet pipe 6 into the interior of the feeding cylinder 3, and then the nutrient solution passes through the liquid delivery pipe 7 at the bottom of the feeding cylinder 3 into the sealed tube composed of the first liquid outlet pipe 12 and the second liquid outlet pipe 16.

The tube 16 moves downward inside the connecting frame 13, so that the second liquid outlet pipe 16 coincides with the hole of the connecting frame 13, so that the nutrient solution is fully sprayed into the interior of the box 1 from the hole where the connecting frame 13 and the second liquid outlet pipe 16 coincide under the action of air pressure, so that the nutrient solution can be sprayed more evenly and quickly into the interior of the box 1, so that the microorganisms can fully contact the nutrient solution, and the spraying step is repeated again, and the amount of nutrient solution sprayed each time is the same. After that, the double-headed motor 19 on the other side drives the corresponding two first bevel gears 20 to rotate, and the first bevel gear 20 and the second bevel gear 21 engage to drive the threaded rod 22 to rotate in the same direction inside the box 1. Under the same-direction rotation of the four threaded rods 22, the cleaning frame 23 can move up and down reciprocatingly inside the box 1, and the inner wall of the box 1 is stably cleaned. Finally, the purified exhaust gas is output from the outlet pipe 25.
