[0017] Working principle of the invention: The equipment is mainly used for dust removal and dust suppression during coal transportation, and has two use processes: dust removal during transportation and dust suppression during falling coal.

[0018] One is the dust removal during the transportation process. During the transportation process, coal is conveyed on the conveyor belt. The dust generated during the transportation process is sucked into the dust removal box through the dust inlet ramp under the action of the exhaust fan. The water source is supplied by the water inlet pipe, and is transported through the distribution pipe. Then, through the spraying action of the dust removal sprinkler head, it is fully mixed with the dust in the dust removal box and adsorbs the dust, so that the dust and water droplets form sewage. The sewage gathers on the forward slope and finally falls into the sewage collecting slope. The sewage collecting pipe will collect the sewage. In this process, the dust is absorbed.

[0019] The second is dust suppression of falling coal. The coal is transported on a conveyor belt. When it is transported to the front end of the belt, the coal will fall from the belt. The sewage collection spray pipe installed on the bottom side of the sewage collection pipe will spray the sewage out from the sewage collection spray pipe. The falling coal and sewage will mix to reduce the generation of dust, and the dust mass in the transportation process will eventually return to the coal.

[0020] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
