in the relative rotation process of the two rotors, the air bag on the top surface of one rotor is extruded with the convex part on the other rotor, the air bag releases air into the air pipe and the air pressure channel after being extruded, and the blocking block of the air pipe and the air pressure channel is pushed to enter the vent hole to block the vent hole, so that the filter cavity is sealed;
simultaneously, the flexible piece card in the middle of the gasbag is gone into to the joint mouth in, and the sealing block who blocks up the joint mouth pushes away from the joint mouth for joint mouth and connecting pipe, negative pressure chamber intercommunication realize that air suction mechanism is to the extraction of negative pressure chamber, connecting pipe, joint mouth gas, and then realize absorbing the particulate matter of filter screen in the filter chamber, make the particulate matter enter into to the joint mouth along the pore of flexible piece, and finally get into the negative pressure chamber, be absorbed by air suction mechanism, accomplish the cleanness to filter screen in the turning.
10. The exhaust gas treatment method according to claim 9, wherein the exhaust gas is filtered by the filter net in a layer-by-layer manner through the honeycomb structure of the filter net.
