The sort that industrial waste gas pollutes and processing method

Pollution of industrial off-gas treatment basically is the mankind be being produced and mineral resources fuel burns in day activity process (coal and oil) , the drilling when mining, explosion, building materials is destroyed, screening, smelt casts what wait and form. Air pollution owner wants a few kinds to have oxide of sulfur of dust grain, carbon dioxide, 2 oxidation or nitrogen.

What the skill of contaminant of industrial off-gas treatment is aimed at contaminant is different and different. Skill of off-gas treatment of grain contaminant industry is aimed at grain contaminant bead diameter size, method of industrial off-gas treatment basically has dry method, wet, filter and electrostatic 4 kinds, the most commonly used is bag type dust catcher (filter) , tornado type dust catcher (dry method) , bubble dust catcher (wet) etc. Rise as what to removing dust power asks, electrostatic remove dust also begin to use stage by stage rise.

Electric dust collector is comprised by two electrode. After electrify is being added to shed voltage between electrode, electric field produces between electrode. Grain contaminant traverses electric field along with waste gas, particle is collided by ion and make its contain charge. Electrified dust to dust collection extremely mobile, achieve plate. Such, the contaminant in air is by adsorption on plate, make air gets depurative, grit also falls into ash bucket because of the gravity of itself.

Electric dust collector can catch market bead of all and fine pink or droplet, and handle waste gas measure big, use temperature scale wide, consequently by industrial business wide to value. But because cover an area of an area big, contributive big, make a few small and medium sized business cannot choose.
