Automobile exhaust absorption and purification device and using method thereof

Abstract

The invention belongs to the field of air pollution prevention and control, and particularly relates to an automobile exhaust absorption and purification device and a using method thereof. The automobile exhaust absorption and purification device comprises an isolation section, a first-stage wind power section, an exhaust absorption section, a second-stage wind power section and a purification section. The isolation section comprises an exhaust port, a fixing ring, a filter screen, a first connecting position and a wind guide device, and the first-stage wind power section comprises a first-stage fan and a second connecting position. The exhaust absorption section comprises spiral pipes, a water tank, a third connecting position and particles, the second-stage wind power section comprises a second-stage fan and a fourth connecting position, and the purification section comprises a purification agent and a drying agent. Harmful gas in exhaust is fully physically absorbed in a transverse and longitudinal double-spiral-pipe mode, and absorption is achieved in combination with a chemical agent, so that it is ensured that harmful gas in exhaust can be completely absorbed, and the maintenance cost can be reduced by adopting a multi-stage assembly mode.

Description

technical field [0001] The invention belongs to the field of air pollution prevention and control, and in particular relates to an automobile tail gas absorption and purification device and a use method thereof. Background technique [0002] With the rapid development of the global economy, people have realized the damage to the environment caused by rapid economic development. In recent years, the smog in our country has become more and more serious. Most of these come from the emission of automobile exhaust. In order to reduce the emission of automobile exhaust, Started to vigorously support the research and development of automobiles. Automobiles can reduce carbon dioxide emissions, but there are still a lot of sulfides, nitrogen oxides and some small solid particles in automobile exhaust, so that air pollution gradually begins to show soot and automobile exhaust composite pollution. This has exacerbated the difficulty of treatment; although there are also automobile exha...

[0002] With the rapid development of the global economy, people have realized the damage to the environment caused by rapid economic development. In recent years, the smog in our country has become more and more serious. Most of these come from the emission of automobile exhaust. In order to reduce the emission of automobile exhaust, Started to vigorously support the research and development of automobiles. Automobiles can reduce carbon dioxide emissions, but there are still a lot of sulfides, nitrogen oxides and some small solid particles in automobile exhaust, so that air pollution gradually begins to show soot and automobile exhaust composite pollution. Exacerbating the difficulty of treatment; although there are also automobile exhaust purification products on the market, most of them are more restrictive and the absorption and conversion efficiency is not obvious
