Claims

[Claims for Utility Model Registration] 1. A circulating fluid injection pipe in the upper part, a liquid reservoir in the lower part, and an overflow pipe connected to the overflow opening of the liquid reservoir, and the liquid reservoir In an absorption tower of a wet gypsum desulfurization equipment, the absorption tower has a return pipe that extracts a part of the liquid from which gypsum has been separated in the gypsum separation equipment and returns the liquid to the tower, and is provided inside the overflow pipe. A blockage prevention device for an absorption tower overflow pipe, characterized in that it is further equipped with a spray nozzle that is connected to the return liquid pipe and injects the return liquid into the absorption tower. 2. Blocking of an absorption tower overflow pipe according to claim 1, wherein the spray nozzle for injecting the returned liquid into the absorption tower is provided at a position away from the overflow port by an appropriate distance in the direction outside the absorption tower. Prevention device. 3. The absorption tower overflow pipe according to claim 1 or claim 2, wherein the spray nozzle that injects the return liquid into the absorption tower injects the return liquid at least onto the half-lower peripheral surface of the overflow port. Anti-occlusion device. 4. The blockage prevention device for an absorption tower overflow pipe according to claim 1, 2 or 3, further comprising a cover provided in the absorption tower so as to cover the upper half circumferential surface of the overflow opening.
