Through the arrangement of the fan 18, the purpose of collecting the exhaust gas inside the air shaft 1 can be achieved.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 3 Among them, a filter screen 6 is fixedly connected inside the filter frame 4. A plurality of high-pressure nozzles 7 are fixedly communicated with the outer surface of the U-shaped nozzle 5. The U-shaped nozzle 5 is fixedly inlaid with the collection pipe 2. Rubber sealing strips 8 are fixedly connected to the front and back of the filter frame 4. Through the arrangement of the rubber sealing strips 8, the sealing performance at the edge of the filter frame 4 can be improved. Rotating shafts 9 are fixedly connected to the upper surface and the bottom of the filter frame 4. Both rotating shafts 9 are rotatably connected to the collection pipe 2. The top of the uppermost rotating shaft 9 is fixedly connected to a worm gear 10. Two power plates 11 are fixedly connected to the upper surface of the collection pipe 2. A worm 12 is rotatably connected between the two power plates 11. The worm 12 is meshed with the worm gear 10. The front end of the worm 12 is fixedly connected to the output end of an external motor. Through the arrangement of the worm 12 and the worm gear 10, the purpose of turning over the filter screen 6 can be achieved.

[0033] Please refer to Figure 1 、 Figure 2 andFigure 3 , a waste discharge tank 13 is fixedly connected to the bottom of the air shaft 1. A waste discharge pipe 14 is fixedly embedded in the inner bottom wall of the waste discharge tank 13. An electromagnetic valve 15 is installed inside the waste discharge pipe 14. Through the setting of the waste discharge pipe 14, wastewater can be discharged. A connecting pipe 16 is fixedly communicated with the outer surface of the U-shaped spray pipe 5. The connecting pipe 16 is fixedly communicated with the output end of an external water pump. Through the setting of the connecting pipe 16, it is convenient for the user to connect with the external water pipeline.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 , a control processor 20 is installed on the upper surface of the collection pipe 2. An exhaust gas concentration monitoring probe 21 is installed on the inner wall of the air shaft 1. The exhaust gas concentration monitoring probe 21, the electromagnetic valve 15, the external water pump, the ultraviolet photocatalytic treatment device 17, the fan 18, the air flow detection sensor 19 and the external motor are all electrically connected to the control processor 20. Through the control processor 20, the control and monitoring purposes of the exhaust gas concentration monitoring probe 21, the electromagnetic valve 15, the external water pump, the ultraviolet photocatalytic treatment device 17, the fan 18, the air flow detection sensor 19 and the external motor can be achieved.

[0035] In a sewage pipe network exhaust gas collection and treatment device in this embodiment, through the provided grille 3 and filter screen 6, larger foreign objects and dust particles can be filtered respectively, so as to prevent foreign objects from entering the interior of the ultraviolet photocatalytic treatment device 17, improve its exhaust gas treatment effect and delay its maintenance cycle. Through the provided exhaust gas concentration monitoring head, the exhaust gas inside the air shaft 1 can be monitored in real time. After reaching the preset threshold value, the control processor 20 can automatically drive the fan 18 to collect the exhaust gas. Through the provided high-pressure nozzle 7, the filter screen 6 can be automatically cleaned to prevent the filter screen 6 from being blocked and affecting the exhaust gas permeability.

[0036] It should be noted that the electromagnetic valve 15 can be opened downward.

[0037] The working principle of the above embodiment is as follows. During use, after the exhaust gas concentration monitoring probe 21 detects that the exhaust gas reaches the threshold value, the fan 18 starts to suck in the external exhaust gas, and the larger particles and floating substances in the exhaust gas are filtered by the grille 3 and the filter net 6. The exhaust gas enters the ultraviolet photocatalytic treatment device 17 for treatment. During the process of exhaust gas collection, after the air flow detection sensor 19 detects a decrease in the gas flow rate, it can enable the control processor 20 to start the external water pump and motor, and output water flow through the high-pressure nozzle 7 to clean the filter net 6. During the cleaning process, the external motor drives the worm 12 and the worm gear 10 to rotate, which can drive the filter frame 4 and the filter net 6 to rotate. Cooperating with the spraying of the high-pressure nozzle 7, the filter net 6 can be fully cleaned. After the cleaning is completed, the wastewater flows into the waste discharge tank 13. The control processor 20 can drive the solenoid valve 15 to open, so as to discharge the wastewater through the waste discharge pipe 14, ensuring the permeability of the filter net 6 and at the same time delaying the maintenance cycle of the ultraviolet photocatalytic treatment device 17.
