Dust separator

Abstract

The present invention belongs to the dust and mist separator in the exhaust gas purification system. It is characterized in that a spraying device is installed in the exhaust gas inlet pipe to spray umbrella-shaped mist-shaped water to pretreat the dust particles contained in the exhaust gas. When in contact with the dust and mist separation device with a number of airflow filter channels arranged by grid pieces with a special geometric structure between 25mm and 30mm, a vortex backflow and centrifugal force are formed; through the action of centrifugal force, the moisture absorbs fine dust particles. The ability to make the particle size and weight of the water containing fine dust particles increase to form water droplets, which are then pushed into and intercepted by the horizontally flowing exhaust gas into the twelve negative pressure areas inside and outside the U-shaped recovery tank and three Herringbone In the collection ditch, it settles vertically along the twelve negative pressure areas and the wall of the herringbone collection ditch by its own weight, and flows into the wastewater outlet pipe. In this way, the purpose of effective dust and mist separation with a dehumidification rate of more than 99% and a dust removal particle size of ≤20 μm is achieved.

Description

technical field [0001] The invention relates to a dust and mist separator, in particular to a dust and mist separator in an exhaust gas purification system. Background technique [0002] The dust and mist separation device used in the exhaust gas purification system currently has a single structure in the domestic exhaust gas emission treatment equipment, and does not pre-treat the exhaust gas emission. Although this kind of equipment simply purifies the exhaust gas emission, it cannot be effective. The actual effect of separating dust and mist. The structural shape of the grille sheet used for the internal filtration of exhaust gas treatment adopts a herringbone combination type, that is, two pieces of 45° symmetrical slopes are connected to form a group, and four or five sets of grille sheets are connected to form a herringbone combination type. Structure, in this way arranged into a number of airflow filter channels. When the exhaust gas passes through the airflow filte...

AI Technical Summary

Problems solved by technology

Due to the lack of pre-treatment of the exhaust gas, and because of the structural defects and single shape of the herringbone combination grille, the backflow and vortex generated by the exhaust gas flowing into the air filter channel are also small, and the centrifugal force formed is insufficient. An effective negative pressure area is formed on the airflow filter channel, so that the ideal separation effect cannot be achieved
