Background

On the working face of a coal mine, in the process of the mining operation of the fully-mechanized coal mining machine, coal and rocks are broken during excavation, and a large amount of dust is formed. Coal mining machines and belt conveyors also produce large amounts of dust where they fall. The diffused dust seriously threatens the physical health of coal miners, and the incidence rate of pneumoconiosis is obviously higher than that of other industries. Therefore, a dust remover is needed in the production process of the mine to absorb and purify the coal dust air in the mine environment and then discharge the coal dust air. At present, most mining dust collectors adopt wet dust collectors, dust-containing gas is in close contact with liquid, and the particles are captured or enlarged or kept in a fixed container to achieve the effect of separating water from dust by utilizing the inertial collision of water drops and the particles or the full mixing action and the action of the water and the dust. However, when the wet dust collector removes dust, water drops containing dust particles adhere to the spray head due to the high humidity of the spray head of the dust collector; because the coal mine contains calcium sulfide, magnesium sulfide and the like and also contains organic matters, the substances cannot be removed in time and can cause corrosion to a dust remover; therefore, a cloud and mist dust removal device for the fully mechanized excavation face and a using method thereof are provided.
