Abstract:
The invention relates to a dry circulating fluidized bed flue gas desulfurization reaction tower, belonging to the field of flue gas purification technology. Said invention includes tower body and flue gas inlet, flue gas outlet, spraying water inlet and spraying powder outlet which are connected with the tower body. Said tower body is composed of upper and lower two sections which are connected by means of designed Venturi section. The lower section of said tower body is preseparation chamber with buffer action, the connection form of the preseparation chamber and the described flue gas inlet adopts a tangetial gas-feeding turnable type structure, the bottom portion of preseparation chamber is equipped with a conical ash-falling mouth. The upper section of said tower body is a straight barrel section; the lower portion of said straight barrel section is connected with the described spraying powder inlet and spraying water inlet placed over the spraying powder inlet. In the interior of upper portion of said straight barrel section an internal separation member with inertial separation action is mounted, and the described flue gas outlet is placed over the internal separation member and connected with outer wall of said straight barrel section.
