Ash hopper dust removal device

Abstract

The invention discloses an ash hopper dust removal device comprising an ash hopper, wherein the ash hopper adopts an interlayer heat preservation structure, a plurality of vibrators are respectively arranged on an outer wall of the ash hopper, a heating device is arranged in the interlayer heat preservation structure of the ash hopper, a connecting gap of the heating device and the interlayer heatpreservation structure of the ash hopper is filled with a heat preservation filler, a partition device is arranged at the bottom end of the ash hopper in a penetration manner, a crushing drum deviceis arranged at the bottom end of an ash discharge valve, and the ash discharge valve is arranged at the bottom end of the crushing drum device. The ash hopper dust removal device provided by the invention is capable of preventing the agglomeration of an ash body due to condensation caused by temperature reduction and preventing the ash body from being attached to the inner wall of the ash hopper,and is also capable of efficiently crushing the ash body.

Description

technical field [0001] The invention relates to the field of dust removal equipment, in particular to the field of green dust removal equipment, and specifically refers to an ash hopper dust removal device. Background technique [0002] At present, the ash hopper in the electrostatic precipitator only relies on the designed oblique angle and gravity to make the ash fall down to the ash discharge port. However, during the falling process, due to the drop in temperature, the moisture content of the ash body increases, resulting in the ash body becoming fluid. , and gradually coagulates into a block. After a long time, it will accumulate in front of the ash discharge port, and the volume is larger than the space of the ash discharge port, so that the ash body cannot continue to fall and collect. In addition, because the ash body can be reused as part of the raw materials Secondary crushing is performed after collection. [0003] For example, the dust collector with the patent ...

AI Technical Summary

Problems solved by technology

[0002] At present, the ash hopper in the electrostatic precipitator only relies on the design bevel and gravity to make the ash fall down to the ash discharge port, but during the falling process, due to the temperature drop, the moisture content of the ash body increases, causing the ash body to become fluid , and gradually condense into lumps, which will accumulate in front of the ash discharge port after a long time, and the volume is larger than the space of the ash discharge port, so that the ash body cannot continue to fall and collect. In addition, since the ash body can be reused as part of the raw material, it needs to Secondary crushing after collection

[0003] For example, the patent application number is CN201721853504, which is a convenient dust collector for cleaning dust. Its technology is likely to cause the ash body to form a large block when the temperature drops and the moisture increases and condenses to room temperature, so that the ash body cannot fall to the collection device. The crushing device is easily damaged because the crushing rod is perpendicular to the rolling bar, and cannot operate normally when the ash body is condensed and agglomerated
