Automobile exhaust purifier capable of automatically removing coarse carbon particles

Abstract

The invention relates to the field of automobile accessories, in particular to an automobile exhaust purifier capable of automatically removing coarse carbon particles. The automobile exhaust purifiercomprises a left outer cylinder, a right outer cylinder and a honeycomb carrier, the left outer cylinder and the inner wall of the right outer cylinder communicate and are connected detachably, innercylinders are installed in the left outer cylinder and the right outer cylinder, and the honeycomb carrier is arranged between the two inner cylinders. Honeycomb holes of the honeycomb carrier are internally coated with catalyst layers. Electromagnets and outer magnets are arranged on the inner cylinders and in a cavity of the left outer cylinder and a cavity of the right outer cylinder, an innermagnet is arranged in each inner cylinder, a coarse carbon filter net is arranged on each inner magnet, and the inner magnets and the outer magnets correspond to each other in position. Coarse carbonparticles on the inner cavities and the coarse carbon filter nets can be automatically removed, the coarse carbon particles are prevented from affecting the activity of catalysts after being broughtinto a catalytic device, meanwhile, the catalytic device can be rapidly disassembled to remove the coarse carbon particles, and the catalyst activity of the catalytic device is ensured, and hydrocarbon, NOx, carbon monoxide and the like in automobile exhaust can be better purified.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an automobile exhaust gas purifier for automatically cleaning coarse carbon particles. Background technique [0002] With the continuous development of economy and society and the improvement of people's living standards, automobiles have become a popular means of transportation in people's daily life. However, with the continuous increase in the use of automobiles, the harm caused by automobile exhaust to the atmospheric environment is also increasing. Clearly, automobile exhaust pollution has become the main source of air pollution in cities, and the main air pollutants in cities are inhalable particulate matter. Dealing with automobile exhaust has become an urgent problem in today's economy and society. [0003] The main components of exhaust gas emitted by automobiles are hydrocarbons, nitrogen oxides, carbon monoxide, and particulate carbon. Three-way catalysis mainly converts har...

Problems solved by technology

However, during the exhaust gas treatment process, a large amount of coarse carbon particles will adhere to the inner cavity through which the exhaust gas passes and the coarse carbon filter net, and then blockage will occur. Particulate carbon will reduce the surface activity of the catalyst or even fail, so it is of great practical significance for those skilled in the art to design an automobile exhaust purifier that automatically cleans the coarse carbon particles in the inner cavity and the coarse carbon filter.
