[0002] When a large number of people gather in large indoor buildings (such as shopping malls, auditoriums, convention and exhibition centers, etc.), there will usually be a large number of vehicles entering and exiting the underground parking lot. Vehicles will produce automobile exhaust when driving in the underground parking lot. Automobile exhaust includes solid suspended particulate matter, carbon monoxide, carbon dioxide, hydrocarbons, lead and sulfur oxides, etc. Underground parking lots are usually in closed indoor areas. The emission of automobile exhaust will have an impact on the environment of the underground parking lot. It is usually necessary to equip the underground parking lot with an exhaust gas circulation treatment system to treat the indoor polluted air and discharge it outdoors to ensure the freshness of the air in the underground parking lot. The exhaust gas treatment pipeline plays a vital role in the exhaust gas circulation treatment system.

[0023] The specific operation is as follows: the servo motor 701 drives the screw rod 1 702 and the bevel gear 1 703 to rotate, the bevel gear 1 703 drives the bevel gear 2 704 to drive the screw rod 2 705 and the bevel gear 3 706 to rotate, the bevel gear 3 706 drives the bevel gear 4 707 to drive the screw rod 3 708 and the bevel gear 5 709 to rotate, and the bevel gear 5 709 drives the bevel gear 6 710 to drive the screw rod 4 711 to rotate, so that the four screw nuts 712 are respectively displaced outside the screw rod 1 702, the screw rod 2 705, the screw rod 3 708 and the screw rod 4 711 until the four filter screens 714 are closed, so as to achieve the effect of filtering the gas when passing through and reducing the solid particles and dust entering the deep part of the main pipeline 1.
