REMOVAL OF SOLID PRODUCT FROM FLUE GAS SCRUBBER USING LIME (STONE) SLURRY

摘要

A method for the continuous extraction of washing suspension solids from a tower scrubber 1 of a flue-gas desulphurizing plant working with lime or limestone as an absorbing medium, in which a circulating flow is imposed on the washing suspension in the residence tank 2 of the scrubber and washing suspension is drawn off from the zones having an increased concentration of solids which form in the course of this. In one embodiment the washing suspension is drawn off from the zone with an increased concentration of solids forming in the central bottom region of the residence tank. IMAGE
