Abstract

The invention discloses a plasma and electrostatic adsorption coupled automobile emission purifier and purification method and belongs to the technical field of automobile emission purification. The plasma and electrostatic adsorption coupled automobile emission purifier and purification method are aimed to solve the problems of bad universality and bad processing effect of an existing automobile emission processing technology. The purifier comprises an emission purification pipe, a glass slideway, a sinusoidal high-voltage electrode, a direct-current high-voltage electrode and a grounding electrode, the emission purification pipe is divided into an emission lead-in region, a plasma processing zone, a transition zone, a static dust removing zone and an emission discharge zone in sequence from the head end to the end, the glass slideway is fixed on the outer surface of the bottom of the emission purification pipe, and the grounding electrode is arranged on the glass slideway in a sliding mode. The purification method includes that cooling the automobile emission at the emission lead-in zone; respectively carrying out plasma reaction and high-voltage static dust removing on the automobile emission in the plasma processing zone and the static dust removing zone; enabling the grounding electrode to slowly move out of the plasma processing zone to be corresponding to the static dust removing zone. The plasma and electrostatic adsorption coupled automobile emission purifier and purification method are used for the automobile emission purification.

Description

technical field [0001] The invention relates to an automobile tail gas purifier coupled with plasma and electrostatic adsorption and a purification method, belonging to the technical field of automobile tail gas purification. Background technique [0002] At present, the number of cars in the world is increasing rapidly. Taking my country as an example, the number of cars is increasing rapidly at an annual growth rate of 13-15%. By 2014, the total number of cars in China has reached 137 million. Due to the high emission factor of automobile exhaust, black smoke particles, NOx, CO and HC in the exhaust have become the main sources of air pollution. According to the 2013 Air Quality Report of 74 Cities in the Beijing-Tianjin-Hebei Region, the Yangtze River Delta Region, the Pearl River Delta Region and Municipalities, Provincial Capital Cities, and Cities with Independent State Planning issued by the Ministry of Environmental Protection in 2014, the primary pollutant in 74 cit...
