Abstract
The invention relates to a boiler capable of purifying flue gas. The boiler comprises a boiler body, a dust removal tower, a reaction tower and an absorption tower. A flue gas exhaust pipe on the boiler body is connected with the dust removal tower. The gas outlet of the dust removal tower is connected with the gas inlet of the reaction tower through a guide pipe. The gas outlet of the reaction tower is connected with the gas inlet of the absorption tower through a guide pipe. By arranging the dust removal tower, the reaction tower and the absorption tower which are connected with the boiler body in sequence, flue gas generated after fuel in the boiler body is burned is subjected to a series of purification measures, and the pollution of hazardous substances in the flue gas to the environment can be reduced effectively. The arranged dust removal tower is capable of primarily removing floating dust in the flue gas, and when a plurality of dust removal plates arranged in the dust removal tower are perpendicular to the flue gas flowing direction, the dust removal effect is optimal. A plurality of catalyst layers are arranged in the reaction tower, ammonia gas is introduced into the reaction tower to react with the hazardous substances in the flue gas so that the hazardous substances can be removed, and the flue gas is finally exhausted after being absorbed by absorption liquid in the absorption tower.
