DAMP FLUE GAS DESULPHURATION SYSTEM.

摘要

This invention supplies a damp flue gas desulphuration system for removing the sulphur dioxide present in flue gas by means of absorption within an absorbent aqueous paste, the system comprises a chimney tower which has at the bottom a tank to retain an absorbent aqueous past; a circulation pump to feed the absorbent aqueous paste into the tank to a flue gas input section in the top part of the absorption tower and to put into contact the absorbent aqueous past with the flue gas; and an aqueous paste preparation compartment provided in a side of the tank absorption tower and separated by flue gas passage section through a wall division which has its lower end submerged below the absorbent aqueous past surface of which the absorbent and the water that constitute the absorbent aqueous past are directly introduced into the aqueous paste preparation compartment. Thus, the absorbent supply system improves to achieve a marked simplification of the equipment.
