Dry powdered activated carbon injection equipment and dry powder activated carbon injection

摘要

PROBLEM TO BE SOLVED: To enable finer injection amount control during injection of a dry activated carbon powder.;SOLUTION: Dry activated carbon powder injection equipment comprises: an activated carbon storage tank 11 that stores a dry activated carbon powder; a supply amount variable supply part 12-14 that cuts out the dry activated carbon powder DC stored in the activated carbon storage tank 11 and supplies it at a constant amount; a dissolving tank 15 that mixes the dry activated carbon powder DC supplied from the supply part 12-14 with dissolving water supplied separately at a constant flow rate to continuously produce activated carbon slurry having a predetermined concentration; an activated carbon slurry storage tank 32 for storing the slurry produced continuously in the dissolving tank 15; and a flow rate variable injection pump 33 that supplies the slurry stored in the activated carbon slurry storage tank 32 to an injection point under pressure.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2016,JPO&INPIT
