Multi-effect pretreatment device for industrial waste gas

The utility model discloses a multi-effect pretreatment device for industrial waste gas, which comprises an activated carbon adsorption area, a desulfurization and denitrification chamber, a bipolar charge unit, a coagulation area and a cooling water channel arranged along the wall which are sequentially arranged along the airflow direction, and is characterized in that the activated carbon adsorption area consists of five groups of activated carbon boxes which are uniformly distributed at intervals; the multi-effect pretreatment device for the industrial waste gas can effectively adsorb harmful impurities in the industrial waste gas, efficiently desulfurize and denitrate, reduce the temperature of the waste gas, utilize the coupling effect of an electric field and a turbulent flow field, and improve the pretreatment efficiency of the industrial waste gas. The collision probability of fine particles can be improved, fine particle coagulation is promoted, the particle size is increased, and subsequent dust rem
