Automobile exhaust treatment device and method

Abstract

The invention provides an automobile exhaust treatment device and method. The automobile exhaust treatment device comprises a treatment device body and a steam fog catcher; one end of the treatment device body communicates with one end of the steam fog catcher; the other end of the treatment device body is provided with a gas inlet; the other end of the steam fog catcher is provided with a gas outlet; a liquid distribution net is fixed in the treatment device body; a steam fog catching net is fixed in the steam fog catcher; substances used for absorbing steam are arranged in the steam fog capturing net; a liquid distributor is fixed above the liquid distribution net and is located in the treatment device body; a liquid inlet is formed in the top of the liquid distributor; a first liquid storage tank is fixed under the liquid distribution net and communicates with the treatment device body; and a first liquid outlet is formed in the bottom of the first liquid storage tank. The automobile exhaust treatment device and method have the advantages that automobile exhaust reacts with dilute alkali liquor, so that CO2, SO2, NO2 and other gases in the exhaust are removed, and the steam in reacted gas can be intercepted through the substances which can adsorb the steam and are placed in the steam fog catcher so that the discharged gas can be dry and clean.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment, in particular to an automobile tail gas treatment device and a treatment method.
