A smoke washing box of an automobile exhaust treatment device

Abstract

The invention discloses a smoke washing box of an automobile exhaust gas treatment device. The smoke washing box comprises a box body, and a gas outlet pipe is connected to the position, near the edgeside, of the upper end of the box body in a threaded mode. A gas inlet pipe is disposed on the side, away from the gas outlet pipe, of the upper end of the box body symmetrically, and a flange is connected to the outer side of one end of the gas inlet pipe in a threaded mode. The smoke washing box of the automobile exhaust gas treating device is provided with a U-shaped smoke washing pipeline, deceleration baffles and a buffer solution tank, the U-shaped design increases the flow distance of flue gas in the pipeline, and at the same time, an eluting solution is enabled to have enough time tobe in full contact with the flue gas by cooperating with the deceleration effect of the deceleration baffles, and the absorption rate of the flue gas is improved. And meanwhile, the U-shaped design can save space compared with other straight pipelines, the whole smoke washing box is divided into two rinsing areas, and the step of rinsing with a buffer solution is added, so that more harmful ingredients in the flue gas can be removed, the effect of smoke washing is improved, and the smoke washing box is applicable to different working conditions and brings better use prospects.

Description

technical field [0001] The utility model relates to the field of tail gas treatment, in particular to a smoke washing box of an automobile tail gas treatment device. Background technique [0002] Automobile exhaust is the exhaust gas generated during the use of automobiles. It contains hundreds of different compounds. The pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. With the development of technology With the progress, people have introduced the structure of the smoke washing box in the treatment of automobile exhaust gas to improve the ability of exhaust gas treatment. [0003] Existing technology A structure of a smoke washing box for a diesel generator set (Chinese patent application number CN201320282523.0) includes a closed box, the upper panel of the closed box is extended with inlet and exhaust pipes, and the two sides of the closed box are The sides are respectively equipped wit...

[0003] Existing technology A structure of a smoke washing box for a diesel generator set (Chinese patent application number CN201320282523.0) includes a closed box, the upper panel of the closed box is extended with inlet and exhaust pipes, and the two sides of the closed box are The sides are respectively equipped with inlet and drain pipes, and vertical plates are erected in the airtight box to divide the box into two chambers, and the bottoms of the two chambers are connected; the smoke washing box allows the smoke to be combined with water, and the The harmful components of the flue gas are absorbed, so that the dirt in the flue gas can be removed. The structure of the smoke washing box is simple and the design is reasonable, which is conducive to greatly reducing the amount of smoke; but there are many disadvantages, the flow distance of the flue gas in the box is too short , the flow rate is too fast, resulting in short gas-liquid contact time, limited solubility of clean water for smoke, and many harmful components in exhaust gas are insoluble in water; therefore, we propose a smoke washing box for automobile exhaust treatment equipment
