[0002] The SDS desulfurization tower absorbs and strips the sulfide in the flue gas by fully contacting and reacting the flue gas with the injected absorbent, thereby achieving the purpose of desulfurization and purification. The SDS desulfurization tower has the advantages of high desulfurization efficiency, wide adaptability, and stable operation. The ash conveying device is a system that transports waste materials or ash from the boiler combustion chamber to the ash storage or other processing equipment. For circulating fluidized bed boilers, the design and operation of the ash conveying device plays an important role in ensuring the normal operation of the boiler and reducing waste emissions.
[0003] At present, the circulating fluidized bed boiler flue SDS desulfurization tower ash conveying device on the market has the following disadvantages: after the baking soda powder is sprayed into the desulfurization tower, the flue gas and baking soda are mixed to react and absorb the sulfur dioxide in the flue gas, generating flocs, which are adsorbed by the bag dust removal device, and the dust falls into the ash hopper through the automatic cleaning device of the bag dust removal device. However, the general hopper is easy to stay in the ash hopper when conveying ash downward, and the alkaline substances in the ash are more likely to corrode the ash hopper, so the ash on the inner wall of the ash hopper needs to be cleaned regularly;
[0004] For this purpose, we designed an ash conveying device for the SDS desulfurization tower in the flue of a circulating fluidized bed boiler. Utility Model Content
