Description

Technical Field

[0001] The utility model relates to the technical field of dust collector ash hoppers, in particular to a dust collector ash hopper steam heating device. Background Art

[0002] The dust hopper of the dust collector is a device for collecting and discharging dust. In actual use, the smoke and dust deposited on the inner wall of the hopper will form agglomerations after being damp, which will affect the dust removal operation of the dust collector. In order to prevent the ash from becoming damp and agglomerating and to keep the ash discharge smooth, the hopper needs to be heated so that the hopper can discharge ash normally. One of the ways to heat the hopper of the dust collector is steam heating, which is usually used to maintain the temperature in the hopper to prevent the dust from becoming damp, hardened or frozen, and to ensure that the dust can be removed smoothly from the dust collector.

[0003] When using steam to heat the ash hopper of the dust collector, jacket heating can be selected. The ash hopper is designed into a jacket structure, and steam is passed into the jacket. The steam in the jacket is used to heat the ash hopper wall, thereby heating the dust adhering to the inner wall of the ash hopper. However, the flue gas may be affected by various factors during discharge, resulting in continuous discharge of flue gas to one side of the inner wall of the ash hopper, causing more dust to accumulate on that side, and other sides do not need to be heated. The steam is passed into the jacket over the entire area, and it is not possible to heat the side or position with more dust on a single side or over a large or small area. Therefore, in response to the above problems, we provide a new steam heating device for the ash hopper of the dust collector. Utility Model Content
