Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, and more specifically to a dust collector ash lowering pipeline structure which can quickly clear blockages. Background Art

[0002] The main function of the power plant dust collector is to remove the ash accumulation on the boiler heating surface by various means to maintain the thermal efficiency of the boiler and prevent equipment failure and safety hazards caused by excessive ash accumulation. At the same time, the dust collector can also effectively reduce the dust content in the flue gas to meet environmental protection requirements. The dust collector is usually equipped with an ash removal pipe for removing ash accumulation, but when there is a lot of dust in the ash removal pipe, the ash may be blocked. The existing method for clearing the ash removal pipe of the power plant dust collector is mainly to pour water and knock at the impeller of the electric air lock when the ash removal pipe is found to be blocked, and the agglomerated ash blocks are knocked off by vibration. The disadvantages of this method are low efficiency and poor clearing effect. When the ash blocks are seriously agglomerated, they need to be knocked continuously for a long time. The ash pipe is blocked for too long, the ash hopper cannot discharge ash, and a large amount of ash accumulates on the ash hopper, which may cause the ash hopper to deform and collapse and injure people. Therefore, a dust collector lower ash pipe structure that can quickly clear the blockage is needed. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing method for clearing the blockage of the dust removal pipeline of the dust collector of a power plant mainly involves pouring water and beating at the impeller of the electric air lock when the dust removal pipeline is found to be blocked, so as to knock off the agglomerated ash blocks through vibration. The disadvantages of this method are low efficiency and poor clearing effect. When the ash blocks are seriously agglomerated, they need to be beaten continuously for a long time. The ash pipe is blocked for too long, and the ash hopper cannot discharge ash. A large amount of ash accumulates in the ash hopper, which may cause the ash hopper to deform and collapse and injure people. Therefore, a structure is needed to quickly clear the ash pipe. In view of the above-mentioned defects of the prior art, a dust collector lower ash pipeline structure that can quickly clear blockage is provided.

[0004] The technical solution adopted by the utility model to solve its technical problems is:
