Wet type dust collector for crag lane or half coal crag lane

Abstract

The invention mainly relates to a dust reducing and removing device for a mine, in particular to a wet type dust collector for a crag lane or a half coal crag lane suitable for tunneling a working face of the crag lane or the half coal crag lane. The wet type dust collector is formed by combining an air intake pipe assembly, a frame, a wet filter type dust collector, an axial flow fan and a water quality filter component, wherein the wet filter type dust collector, the axial flow fan and the water quality filter are all arranged on the frame; the air intake pipe assembly consists of an air intake square pipe I, an air intake square pipe II, an air intake square pipe III and a negative pressure air duct; the air intake square pipe I, the air intake square pipe II, the air intake square pipe III and the negative pressure air duct are connected in turn; an air inlet at the front of the axial flow fan is connected with the negative pressure air duct; and an air outlet of the axial flow fan is connected with the wet filter type dust collector. The device has efficient dust removing effect, greatly improves the visibility of a tunneller operator, further improves the work efficiency, effectively prevents production workers from pneumoconiosis and plays an important role in ensuring physical and mental health of the workers for tunneling the working face and safe production of a coal mine.

Description

technical field [0001] The present invention mainly relates to a kind of dust-reducing and dust-removing equipment for mines, in particular to a half-coal and rocky roadway wet dust collector suitable for use in the driving face of rocky roadways and half-coal and rocky roadways. Background technique [0002] On the driving face of the coal mine, during the mining operation of the roadheader, coal and rocks are broken during the excavation, forming a large amount of dust. "Coal Mine Safety Regulations" stipulates that the maximum allowable concentration of total dust is 10mg / m 3 , the maximum allowable concentration of respirable dust is 3.5mg / m 3 . Respirable dust refers to dust with particles smaller than 5 microns. This kind of dust will be inhaled into the lungs of workers without hindrance, and often cannot be completely cleared by the respiratory tract. The diffuse dust seriously threatens the health of coal miners, and the incidence of pneumoconiosis is significant...

AI Technical Summary

Problems solved by technology

The roadheader occupies most of the space in the cross-section of the roadway, and there is not enough space for the dust extraction duct to be erected. The small dust removal equipment in use often puts the dust extraction duct behind the roadheader, which is too far away from the dust generation point. Far, so the effect of dust removal is greatly reduced

Moreover, due to the high viscosity of rock powder, it is easy to block the filter screen, so it is not suitable for the working face of rock roadway or semi-coal rock roadway
