Description

Technical Field

[0001] The utility model relates to the technical field of coal powder collectors, in particular to a coal powder filtering collector. Background Art

[0002] A pulverized coal collector is a device used to collect pulverized coal, usually used in pulverized coal combustion systems, such as pulverized coal boilers, hot blast furnaces, etc. The main function of a pulverized coal collector is to separate pulverized coal from flue gas to ensure environmental protection requirements for flue gas emissions, and to recycle pulverized coal to improve combustion efficiency.

[0003] The patent with publication number CN210409890U discloses a coal dust collector which is easy to clean. It includes a collecting shell, a base frame and a filter bag mechanism. The collecting shell is arranged in a cylindrical structure. The bottom of the collecting shell is fixedly installed with a base frame. The base frame is composed of a bottom plate and a support rod. The bottom of the bottom plate is fixedly installed with the support rod. The device has a reasonable and simple structure. The moving wheels on the base frame are flexible to move and convenient to clean slag. It is convenient to disassemble the filter bag mechanism as a whole from the collecting shell for cleaning, maintenance and replacement, thereby ensuring the collection efficiency of the filter bag. The card slot of the upper cover plate is inserted into the card plate to improve the sealing between the filter bag mechanism and the collecting shell. However, the device has Since the suction hood is fixed at the input end of the induced draft fan, the position of the suction hood is fixed. This means that when the suction hood is used to absorb air containing coal powder, it is necessary to adjust the direction of the collector to adjust the orientation of the suction hood while using the moving wheels on the base frame to move the entire collector, thereby ensuring that air containing coal powder in different directions is absorbed. However, as the coal powder is continuously absorbed and collected, coupled with the weight of the collector itself, the collector will become heavier, making it difficult to move and turn, thereby affecting the filtering and collection of the coal powder. For this reason, a coal powder filtering collector is proposed, which solves the problem that the existing coal powder collector is difficult to fully absorb the surrounding coal powder while moving.
