Wet dust removal equipment for underground coal mine

Abstract

The invention relates to dust removal equipment, in particular to wet dust removal equipment for an underground coal mine. The technical problem to be solved by the invention is to provide the wet dust removal equipment for the underground coal mine, which is driven by wind power and can be detached and cleaned. Wet-type dust removal equipment for an underground coal mine comprises two mounting supports, a flow dividing box, first guide pipes, second guide pipes, nozzles and a protective grating, the protective grating is fixedly connected to the mounting supports, the two sides of the mounting supports are fixedly connected with the three second guide pipes in an equidistant distribution mode respectively, the second guide pipes are jointly and fixedly connected with the flow dividing box, and the nozzles are fixedly connected with the flow dividing box. A first guide pipe is fixedly connected to the flow dividing box, and three spray heads are fixedly connected to the installation support in an evenly-distributed mode. When water is sprayed to the air on the left side of the mounting bracket through the nozzles, the effects that coal dust in the air on the left side of the mounting bracket is wetted by water, the water is increased, and fire is difficult to catch are achieved.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a wet dust removal device used in underground coal mines. Background technique [0002] Coal dust pollution will be caused by coal mine excavation, coal mining, transportation and other major links, and the underground ventilation conditions are relatively poor, and the working space is relatively small, so the concentration of coal dust in the underground air will be very high, and the high concentration of coal dust will be harmful to the human body. It will cause great harm to the safety of coal mines. [0003] Patent application CN203525500U, published on April 9, 2014, discloses a wet dust removal device, the wet dust removal device includes a water pump and a wet dust removal device body provided with an air outlet and an air inlet, and the wet dust removal device body From bottom to top, the upper part of the cavity is multi-faceted spherical layer, internal circulation spray laye...

[0003] Patent application CN203525500U, published on April 9, 2014, discloses a wet dust removal device, the wet dust removal device includes a water pump and a wet dust removal device body provided with an air outlet and an air inlet, and the wet dust removal device body From bottom to top, the upper part of the cavity is multi-faceted spherical layer, internal circulation spray layer, activated carbon or biological filler layer, and flushing spray layer. The wet dedusting device also includes an auxiliary container connected to the body of the wet dedusting device through a communication port. When the liquid level in the inner cavity of the device body is higher than the position of the communication port, the liquid level in the inner cavity of the wet dedusting device is equal to the liquid level in the inner cavity of the auxiliary charging container. The container is not driven by wind, which makes the dust removal speed slow. It is not suitable for underground coal mines with narrow space and high dust concentration.
