Automobile exhaust pipe capable of automatically purifying tail gas

Abstract

The invention relates to the technical field of air purification, and discloses an automobile exhaust pipe capable of automatically purifying tail gas. The automobile exhaust pipe comprises a drivingroller, an air inlet pipe and an exhaust pipe body, A set of vertical rotating shaft is rotatably connected to the inner middle of a purification cavity, the top of the rotating shaft upwards and movably penetrates through the top wall of the purification cavity to be fixedly provided with a set of horizontal first driven straight gear, multiple sets of sulfur dioxide removing plates are fixedly mounted on the outer side face of the rotating shaft positioned in the purification cavity at equal intervals, and an activated carbon plate with the same area as the corresponding sulfur dioxide removing plate is fixedly installed on one side of each sulfur dioxide removing plate. A set of moving frame coaxial with the exhaust pipe body is arranged on the inner wall of the exhaust pipe body, a scraper blade tightly attached to and sliding on the inner wall of the exhaust pipe body is fixedly installed on the outer side of the moving frame, and a nut is fixedly connected to the side, facing theinterior of a moving mechanism cavity, of the moving frame. The automobile exhaust pipe has the advantages that waste gas impurity accumulation is automatically prevented, multiple filtration and purification are achieved, and normal emission of waste gas is not affected.

Problems solved by technology

[0002] Automobile exhaust is one of the important sources of urban air pollution. At present, most cities have adopted measures such as vigorously developing public transportation facilities, improving fuel quality, and promoting new energy transportation in response to this problem, but they cannot fundamentally solve the problem of automobile exhaust pollution.

[0003] Chinese patent (notification number: CN 109162795 A, announcement date: 2019.01.08) discloses an automobile exhaust pipe that can purify exhaust gas. An exhaust gas treatment box is installed in the middle of the exhaust pipe. The air intake pipe and the exhaust pipe at the rear form an air outlet pipe; the cross section of the exhaust gas treatment box is larger than the cross section of the exhaust pipe, and the first front chamber, the isolation part, the second front chamber, the first filter layer, and the second front chamber are arranged from front to back. Two filter layers and a rear chamber; the first front chamber communicates with the intake pipe; the exhaust pipe can meet better discharge standards, and at the same time has a light structure and low cost; but the exhaust pipe is simply in the air pipe There are multiple layers of devices for filtering exhaust gas inside. Firstly, the setting of the filter device will affect the speed of automobile exhaust emission, which is not conducive to the use of automobiles. Moreover, after long-term use inside the exhaust pipe, even if the exhaust gas is effectively filtered and purified For the inner wall of the trachea, the dust attached to the gas will still accumulate, which is not conducive to the long-term use of the exhaust pipe
