Abstract
The invention relates to a treatment system for industrial waste gases. A slag flushing tower is established between an electric furnace and a settling tank; phosphorus slags are directly discharged into the tower; a tower inlet is sprayed and cooled by a large amount of flushing water; water flushing slags and generated water vapor enter into the slag flushing tower; a tower outlet is immersed into water; and water and the slags in the tower are discharged into the settling tank. The water vapor in the tower cannot enter into the settling tank due to liquid seal; the water vapor is sprayed by using cooling water at the upper part of the slag flushing tower; the temperature of flue gases is primarily cooled; then the cooled flue gases enter into a spraying tower from the top of the spraying tower for secondarily cooling; a downstream spray pattern is adopted in the spraying tower; and the secondarily-cooled flue gases pass through a wire mesh demister from the bottom of the spraying tower to remove the water vapor, subsequently enter into a fan for boosting, further enter into a packed tower for cooling for the third time, and finally are directly discharged into the atmosphere from a chimney at the top of the packed tower.
