Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a coal transport dust suppressor for a thermal power plant. Background Art

[0002] Thermal power generation is a method of generating electricity using the heat generated by the combustion of fuel. In general thermal power plants, bucket wheel excavators are usually used to transport fuel to the combustion chamber. They are special machinery in bulk material storage yards, but bucket wheel excavators generally generate a large amount of dust when feeding, especially for fuels such as coal. This phenomenon is more obvious. If it is directly discharged into the air, it will cause great pollution to it. In the prior art, dust removal operations are generally performed using simple dust-proof nets. After long-term use, the filter nets will cause the mesh to be clogged, affecting the dust removal effect. Utility Model Content

[0006] The beneficial effects of the utility model are:

[0007] By separately setting up the air inlet, air outlet, dust exhaust port and observation port, air intake, air outlet, dust exhaust and observation work can be performed respectively, which is convenient for the operation of the filter and the user's observation, and is convenient for real-time control of the working status and maintenance.

[0008] By fixing a fixing plate on a fixing rod to separate the left and right areas in the filter, the air is guided to flow upward through the fixing plate, thereby reducing the possibility of air flowing to the observation plate, reducing the possibility of the observation plate being blocked by coal dust, and maintaining the observation effect at the observation plate.

[0009] The air passes through the filter and the rotating blades, and the filter is driven to rotate by the rotating blades. Under the rotation of the electric cleaning roller, the coal dust blocked on the filter can be removed at the lower end of the filter, thereby maintaining the filtering effect at the filter and ensuring the air purification effect.
