Embodiment 1

[0018] The working principle of the present invention is: when the automobile tail gas enters the tail gas purifier from the air inlet, the redox reaction will occur when the tail gas passes through the catalytic oxidant in the pipeline, and the harmful components CO, HC, CH4, NOx, etc. in the tail gas will be converted into CO2, N2 and H2O, leaving only particulate matter. Then pass through the muffler in the black smoke interceptor and the black smoke interceptor to intercept particles. After a long time, the intercepted particles will accumulate a lot on the black smoke interceptor, causing the blockage to be blocked. Therefore, the present invention utilizes recoil function combined with structural design, and forms different exhaust routes by adjusting the opening and closing of valves, so as to realize recoil and remove particulate matter. The recoil of the present invention is mutual, and recoil cleaning can be realized for interceptors (DPF) at different positions by ...

Abstract

The invention provides an exhaust purifier for backflushing and removing black smoke blocker particles through exhaust. In a dynamic state, exhaust purification and removal of the black smoke particles in a blocker can be carried out at the same time, and the black smoke blocker is purified. A gas inlet of a gas inlet pipe is sequentially connected with a gas inlet pipe upper section, a gas inlet valve, a gas inlet pipe lower section, the black smoke blocker, an exhaust pipe upper section, an exhaust valve, an exhaust pipe lower section and an exhaust outlet. A backflushing gas inlet pipe is connected between the gas inlet pipe upper section and the exhaust pipe upper section. In a forward working state of the exhaust purifier, the black smoke particles are blocked, and in a reverse working state, the particles adsorbed to the black smoke blocker are removed reversely. Gas flow valve switching is carried out by controlling closing through the valves, so that backflushing, blocking and regeneration are integrated; the exhaust purifier can be recycled and is long in service life and suitable for smoke with particles in diesel engines, gasoline engines, gas engines and other industrial emission.

Description

technical field [0001] The invention relates to an exhaust gas purifier for backwashing and clearing black smoke interceptor particles by using exhaust gas, and belongs to the technical field of preparation of exhaust gas purifiers for internal combustion engines, especially diesel engines. Background technique [0002] Diesel engines mainly adopt the traditional black smoke interception (DPF) technology in dealing with exhaust gas, using black smoke interceptors. The internal structure of black smoke interceptors includes interceptors and mufflers, because there is diesel combustion These particles are the main components of black smoke, and of course there are harmful gases such as CO and HC, so the black smoke interceptor is used to intercept the particles in the exhaust gas, but there are a large number of particles in the exhaust gas after combustion Therefore, the use of traditional black smoke interceptor technology to intercept black smoke has the following disadvant...
