Description

Technical Field

[0001] The invention relates to the technical field of ash hoppers, in particular to a furnace electric precipitator structure. Background Art

[0002] The ash hopper is a container in the electrostatic precipitator used to collect and store the dust generated after dust removal. It is usually located below the corona electrode and the dust collecting electrode, and has a certain inclination angle and outlet to facilitate the collection and discharge of dust.

[0003] When the treated dust-laden gas passes through the electric field area of ​​the electrostatic precipitator, the charged dust particles are attracted to the dust collecting plate by the electric field force, and then the attracted dust slides into the ash hopper due to gravity. During the long-term use of the ash hopper, the dust inside the hopper will gradually increase. When the dust accumulates to a certain level, it needs to be discharged regularly. However, when cleaning the dust inside the ash hopper, more dust needs to be discharged from the narrow mouth, which can easily cause dust blockage, and some dust will easily remain on the inner wall of the ash hopper, resulting in unclean dust inside the hopper. Summary of the invention
