Description

A kind of vehicle exhaust adsorbent equipment
Technical field
The present invention relates to vent gas treatment field, refer to vehicle exhaust adsorbent equipment especially.
Background technique
Along with the use of automobile is more and more extensive; the discharge amount of vehicle exhaust is about more and more, owing to there being the harmful matter such as dust, CO in vehicle exhaust, and very harmful to the pressure of environment; therefore in order to protection of the environment, the living environment comfortable to people one is extremely important.
Chinese patent discloses the ionization absorbent-type Tail gas measuring device that a kind of Authorization Notice No. is CN204656725U, comprise shell, this shell one end connects automobile tail gas pipe, one end is relief opening, electrical hachure and anode is provided with in shell, this electrical hachure and anode are oppositely arranged, and its direction is coaxial with shell, and this electrical hachure and anode are electrically connected with high pressure electrostatic generator simultaneously.Although this device achieves process to dust and precipitation, there is following shortcoming in this device: 1) for CO gas in vehicle exhaust, this device can not process, very harmful to environment; 2), after dust precipitates by this device, not easily precipitation is got rid of.
Summary of the invention
The present invention proposes a kind of vehicle exhaust adsorbent equipment, facilitates dust out, also achieve the removing to CO gas in vehicle exhaust, and treatment effect is good simultaneously.
