[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal, which is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal, which is an open-pit coal mine. Most of my country's coal mines are underground coal mines. There is a lot of dust underground in coal mines. When machines are operated underground in coal mines, large amounts of dust are generated. Dust reduction treatment is required underground in coal mines to reduce dust interference.

[0003] However, the existing coal mine dust reduction is mostly carried out through bag dust collectors. Since the bag dust collector separates dust from air through the filter holes of the bag, there is a large pressure drop during filtration, and the air filtration amount is limited. The filter bag needs to be replaced for long-term filtration, and the filter holes are easily clogged by dust. Based on this, the utility model designs a coal mine dust reduction device to solve the above problems. Utility Model Content

Multiple grooves 5 inside the water-absorbing curtain 4 increase the contact area with the air. The bonding plate 8 wets the water-absorbing curtain 4 through multiple water outlet pipes 9. When the dust-containing air circulates through the multi-section folded space, due to the large mass of dust underground in the coal mine, it tends to move in a straight line due to inertia, and then collides with the water-absorbing curtain 4, and adsorbs and reduces dust through the adhesion force of the water body.
