TECHNICAL FIELD

[0001] The utility model belongs to underground dust removal equipment technical field, concretely relates to a cooling and dust removal device of coal mining working face. BACKGROUND

[0002] Coal mining as our country's important energy acquisition mode, plays the indispensable role in the process of promoting economic development. However, the coal mining working environment is very bad, and a large amount of dust will be produced in the mining process, which not only seriously pollutes the underground operation environment, but also threatens the health of coal miners, and long-term inhalation of dust is easy to cause pneumoconiosis and other occupational diseases. At the same time, due to the poor air circulation in the mine, the mechanical equipment operation, coal oxidation and other factors, the temperature of the mining working face continues to rise, and the high temperature environment not only reduces the labor efficiency of workers, but also increases the risk of heatstroke and other safety accidents.

[0003] In order to solve these problems, the current coal mining enterprises usually adopt multiple ways for cooling and dust removal. Ventilation system is a common means, which introduces fresh air from the ground into the underground through large ventilation equipment, and discharges the dirty air, which alleviates the dust and high temperature problems to a certain extent. But with the increasing depth and intensity of coal mining, it is difficult to meet the actual demand by simply relying on the ventilation system. In addition, spray dust removal is also a common method, which sets up a spray device on the mining equipment or in the roadway, and uses water mist to adsorb dust to achieve the purpose of dust removal. But this way has the problems of limited dust removal effect and large water consumption, and a large amount of water produced by spraying may also affect the quality of coal.

[0004] The existing cooling and dust removal equipment also has many deficiencies. Some equipment has single function, which can only remove dust or only cool, and cannot effectively solve the problems of dust and high temperature at the same time. Although some comprehensive equipment considers the functions of cooling and dust removal, the structure is complex, the cost is high, and the maintenance is difficult, which is a heavy economic burden for some small and medium-sized coal mining enterprises. In addition, the treatment efficiency of dust and heat of many equipment in the actual operation process is low, which cannot meet the requirements of coal mine safety production and environmental protection.
