Exhaust gas filter capable of adjusting exhaust gas resistance and having good blank smoke filtering effect

Abstract

The invention relates to a tail gas filter with good black smoke filtering effect for adjusting tail gas resistance. It includes a filter box (1), a backup carrier (14), a cover plate (10), a support plate (11), a compression spring (12) and a shaft (13), and the inside of the filter box (1) is arranged in sequence along the airflow direction There are a first filter screen (2), a first ceramic honeycomb carrier (3), a second ceramic honeycomb carrier (7) and a second filter screen (8). The present invention is a tail gas filter with good black smoke filtering effect for adjusting tail gas resistance. Under the four-stage filtration of the first filter screen, the first ceramic honeycomb carrier, the second ceramic honeycomb carrier and the second filter screen, the main component is CO , HC, NOx tail gas, reacts into CO2, H2O, N2 and O2, and the micropores on the partition wall can effectively filter the black smoke particles in the exhaust gas, and the black smoke particles will be burned under the action of the catalyst coating, filtering The pressure in the tank can be adjusted at any time to ensure the stable operation of the engine.

Description

technical field [0001] The invention relates to a tail gas filter with good black smoke filtering effect for adjusting tail gas resistance, which is used for automobile tail gas purification. It belongs to the technical field of automobile equipment. Background technique [0002] At present, many ordinary automobile exhaust filters are directly discharged through simple filtration, and the exhaust gas of vehicles equipped with diesel engines contains black smoke particles, and the existing exhaust filters cannot effectively filter black smoke particles, which will cause environmental pollution. [0003] The exhaust filter can only be discharged after being treated. After a long time of use, some non-renewable impurities will adhere to the inner wall of the filter carrier, which will increase the resistance of the exhaust gas discharge. This will cause the power of the engine to drop and pose a safety hazard. Contents of the invention [0004] The purpose of the present i...
