Automobile tail gas treatment device

Abstract

The invention discloses an automobile tail gas treatment device, which comprises an engine exhaust pipe, a carbon dioxide absorber and a precipitation reactor. A carbon dioxide reactor is in a disc shape; an air inlet hole and an air outlet hole are formed in two surfaces of the carbon dioxide reactor; a circle of spiral wall adopting a circle center of the carbon dioxide absorber as a center andradiating from inside to outside is arranged in the carbon dioxide absorber; the air inlet hole is located in the center of the carbon dioxide absorber; the air outlet hole is located on the end of the outermost circle of the spiral wall; the air inlet hole is connected with the engine exhaust pipe; the air outlet hole is connected with the precipitation reactor; carbon dioxide absorption layers are arranged on a front surface and a back surface of the spiral wall; the air outlet hole of the carbon dioxide absorber is connected to the precipitation reactor through a pipeline; the precipitationreactor comprises a solid particulate filter, a heating device and an atomization and precipitation device serially connected sequentially; an oxygen generator is arranged in the heating device; andan air inlet of the solid particulate filter is connected with the air outlet hole of the carbon dioxide absorber through a pipeline.

Description

technical field [0001] The invention relates to the field of automobile exhaust gas treatment, in particular to an automobile exhaust gas treatment device. Background technique [0002] As the acceleration of urbanization and industrialization in recent years has become more and more serious, the weather is smoggy and the visibility is reduced. Vehicle exhaust pollution accounts for a large part of the air pollution. To control the current air pollution situation, we must start from the source. Exhaust fumes from vehicles are treated. Some existing treatment technologies use adsorption devices, but the adsorption devices have the disadvantage of being easily blocked; there is also a direct combustion method to treat automobile exhaust, which has the risk of explosion and is unsafe to use. So need a kind of automobile tail gas purifying device with practicability, safety. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings ...
