Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust prevention equipment, in particular to a high-efficiency wet dust collector for a coal mining machine. Background Art
[0002] As we all know, China is the world's largest coal producer and consumer. Coal consumption accounts for more than 70% of my country's total energy consumption, and it is predicted that it will still account for 60% by 2050. Therefore, coal mining plays a vital role in the national economy. The increasing level of mechanization of coal mining has greatly increased the mining intensity and production concentration of mines, creating good conditions for intensive management and efficient production of coal mines, but the amount of dust generated in mines is increasing, and the dust problem is becoming increasingly serious.
[0003] The mining face is one of the main dust-producing places in the mine. Each link of coal cutting, coal dropping, frame moving, transshipment and transportation in the comprehensive mining face and each link of cutting, transshipment and transportation in the comprehensive excavation face generate a large amount of dust, which seriously pollutes the surrounding environment and poses a great threat to the health of on-site workers.
[0004] One of the most effective dust control measures is to remove dust through filtering by a dust collector. This dust removal method has the highest dust removal efficiency and can effectively reduce the dust content in the air in a short period of time. However, the existing dust collector filtering dust removal requires the installation of filtering materials (filter mesh, filter element) inside the flue. The filtering materials need to be replaced frequently during use, and the cost of use is too high. Utility Model Content

[0014] (III) Beneficial effects
[0015] Compared with the prior art, the utility model provides a high-efficiency wet dust collector for coal mining machines, which has the following beneficial effects:
