Automobile tail gas treatment device

Abstract

The invention discloses an automobile tail gas treatment device. The automobile tail gas treatment device comprises a preliminary purification box; an air inlet pipe is arranged at the left end of thepreliminary purification box; a purification layer is arranged in the purification box and is of a tapered structure; the tapered structure is large in purification area and good in purification effect; the purification layer comprises a first purification layer; and a second purification layer is arranged on the right side of the first purification layer. The automobile tail gas treatment deviceis simple and reasonable in structure, the preliminary purification box carries out the preliminarily purification treatment on air, then tail gas after being subjected to preliminary purification enters a rotating pipe along an air guide pipe and is sprayed into an alkaline washing box, acid gas in the air is absorbed by washing liquid, second fans are driven to rotate when an air flow passes through the rotating pipe, the rotating pipe is driven to rotate by the second fans, stirring rods are driven to rotate by the rotating pipe, and bubbles are smashed, so that the air is sufficiently contacted with the washing liquid, the absorption effect on the acid gas is improved, and the practicability is high.

Description

technical field [0001] The invention relates to an air purification device, in particular to an automobile tail gas treatment device. Background technique [0002] At present, although many exhaust gas purification measures have been taken in the exhaust gas emitted by fuel vehicles, there are still hundreds of different compounds. These tail gases are very serious to the health damage of human body. Sulfur dioxide in the exhaust has a strong pungent smell. When it reaches a certain concentration, it will easily lead to acid rain, resulting in the acidification of soil and water. Automobile exhaust occupies a considerable proportion in the composition of smog, therefore, the air pollution caused by automobile exhaust is a very important reason. [0003] In order to achieve the effect of environmental protection, people install automobile exhaust purification devices at the outlet of automobile exhaust pipes. Some of the current automobile exhaust purification devices adop...

AI Technical Summary

Problems solved by technology

[0003] In order to achieve the effect of environmental protection, people install automobile exhaust purification devices at the outlet of automobile exhaust pipes. Some of the current automobile exhaust purification devices adopt the method of passing the exhaust gas into the liquid that reacts with the exhaust gas, although the harmful components in the exhaust gas can be removed like this, but This purification method has a small contact area between gas and liquid, insufficient reaction, and a large amount of waste of purification liquid. At the same time, the tail gas after purification reaction contains carbon dioxide. If a large amount is discharged into the air, it will also cause greenhouse effect. Now The purification effect of the technical automobile exhaust purification device is not ideal, and cannot meet the requirements of energy saving and environmental protection
