Automobile tail gas absorption device

Abstract

The invention discloses an automobile tail gas absorption device, which comprises an absorber containing aqueous alkali, the absorber is connected with an automobile exhaust pipe, and after entering the absorber and being absorbed by the aqueous alkali, automobile tail gas is exhausted into the atmosphere. The absorber is divided into two main parts, i.e. a liquid chamber and an absorption chamber, the water-soluble characteristic of SO2 / CO2 / NO2 is utilized, the aqueous alkali in the liquid chamber is injected into the absorption chamber, and is in contact with the automobile tail gas entering the absorption chamber, sulfur dioxide is dissolved in water and then reacts with the alkali to produce salt, and thereby the water-soluble acidic gas in the tail gas is thoroughly removed. The liquid chamber and the absorption chamber of the automobile tail gas absorption device are separated from each other, the automobile tail gas absorption device still can normally operate in extremely cold weather, and moreover, the automobile tail gas absorption device is safe and reliable.

Description

technical field [0001] The invention belongs to the field of automobile exhaust gas treatment, and in particular relates to an automobile exhaust gas absorbing device. Background technique [0002] At present, sulfur dioxide in automobile exhaust is directly discharged into the atmosphere. It is extremely harmful to people's health and the natural environment. It is also an important component of "P2.5" in the air. Especially in early winter, the ground temperature It has not completely fallen down yet. In rainy and snowy weather, sulfur dioxide is easily soluble in water, resulting in foggy weather, resulting in poor outdoor visibility, which directly affects our driving safety. Automobile exhaust is the main source of sulfur dioxide in cities. Therefore, reduce the number of vehicles Sulfur dioxide emission in exhaust gas is of great significance to reduce urban air pollution. At the same time, nitrogen dioxide in vehicle exhaust gas is one of the important reasons for aci...

[0002] At present, sulfur dioxide in automobile exhaust is directly discharged into the atmosphere. It is extremely harmful to people's health and the natural environment. It is also an important component of "P2.5" in the air. Especially in early winter, the ground temperature It has not completely fallen down yet. In rainy and snowy weather, sulfur dioxide is easily soluble in water, resulting in foggy weather, resulting in poor outdoor visibility, which directly affects our driving safety. Automobile exhaust is the main source of sulfur dioxide in cities. Therefore, reduce the number of vehicles Sulfur dioxide emission in exhaust gas is of great significance to reduce urban air pollution. At the same time, nitrogen dioxide in automobile exhaust gas is one of the important reasons for acid rain, and carbon dioxide is a greenhouse gas.
