Abstract

The invention discloses a gallery dust remover for coal mine safety production. The gallery dust remover for the coal mine safety production comprises a dust remover shell body, an air inlet, an air outlet, an air inlet filter screen layer, a multi-hole plate, composite tapered water nozzles, an air outlet filter element and a fan. The fan is arranged in the air inlet, the air inlet filter screen layer is arranged on the inner side of the fan, the multi-hole plate is arranged on the other side of the air inlet filter screen layer, a plurality of through holes are formed in the multi-hole plate, the composite tapered water nozzles are inserted into the holes formed in the multi-hole plate, and each composite tapered water nozzle comprises a main tapered water nozzle and a plurality of secondary tapered water nozzles obliquely arranged along the tapered inclined face of the main tapered water nozzle. Through the specific arrangement, the fact that coal dust particles in a coal mine gallery are effectively removed is achieved, the probability of explosion caused by coal dust is reduced, and the safety factors of a coal mine are improved.

Description

technical field [0001] The invention relates to a dust collector, in particular to a dust collector for safe production tunnels in coal mines. Background technique [0002] A large amount of dust is generated during the blasting, loading and transportation operations of underground mining in coal mines. These dusts will be discharged to the ground with the ventilation of the mine, and the particle concentration is as high as 800mg / m 3 Above, the ground environment is seriously polluted, causing the concentration of air pollutants to exceed the standard. At present, my country's current air pollutant comprehensive discharge standard sets a maximum concentration limit of 150 mg / m 3 for particulate matter, and the concentration of particulate matter in mine exhaust air generally exceeds the standard and needs to be treated. [0003] In the dust prevention operation of underground coal seam drilling in coal mines, coal dust formed by nearly 1 ton of raw coal will fly out every...
