Environment-friendly tail gas filter with tail gas discharge resistance adjusting function

Abstract

The invention relates to an environment-friendly tail gas filter for adjusting tail gas resistance. It includes a filter box (1), a backup carrier (9), a cover plate (10), a support plate (11), a compression spring (12) and a shaft (8). The filter box (1) is provided with a first filter A net (2), a ceramic honeycomb carrier (3) and a second filter net (7). The present invention is an environment-friendly exhaust gas filter for adjusting the resistance of exhaust gas. Under the two-stage filtration of the filter screen and the ceramic honeycomb carrier, the exhaust gas whose main components are CO, HC, and NOx is reacted into CO2, H2O, N2, and O2. The micropores on the filter 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, which further improves the exhaust gas purification effect. The pressure in the filter box can be adjusted at any time to ensure the engine's Stable operation.

Description

technical field [0001] The invention relates to an environment-friendly tail gas filter for adjusting tail gas resistance, which is used for purifying automobile tail gas. It belongs to the technical field of automobile equipment. Background technique [0002] At present, many ordinary automobile exhaust filters are directly discharged without filtering, or the filter device is improper, which can easily lead to air pollution and noise pollution; especially, cars equipped with diesel engines, due to the exhaust There are black smoke particles in the air, and the existing exhaust gas filter cannot effectively filter the 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 an...

[0002] At present, many ordinary automobile exhaust filters are directly discharged without filtering, or the filter device is improper, which can easily lead to air pollution and noise pollution; especially, vehicles equipped with diesel engines, due to the exhaust contains black smoke particles, the existing exhaust filter 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.
