Description

Technical Field

[0001] The utility model relates to the technical field of coal mine ventilation and dust removal, in particular to a coal mine ventilation and dust removal device. Background Art

[0002] In coal mining operations, mine ventilation and dust control are important factors to ensure the safety and work efficiency of miners. Since a large amount of dust is generated during coal mining, if this dust is not controlled, it will not only affect the respiratory health of miners, but also may cause serious safety accidents such as coal dust explosions. Therefore, the development of effective ventilation and dust control technology is an important part of coal mine safety production that cannot be ignored.

[0003] In the prior art, ventilation and dust control in coal mines mainly rely on ventilation systems and mechanical filtration devices. These systems remove coal dust particles from the air by continuously introducing fresh air and using filters. However, these filters need to be replaced or cleaned regularly to prevent excessive accumulation of coal dust on their surfaces and affect the filtration efficiency. In addition, conventional sprinkler systems are used for wet dust precipitation, but the water mist distribution of these systems is often uneven and cannot fully cover the area that needs to be controlled.

[0004] Problems with existing technologies include the high maintenance workload and difficulty in cleaning the filters, as well as the limitations of the sprinkler system in terms of dust settling effects. First, traditional filter systems require frequent manual intervention to remove dust accumulation, which not only increases maintenance costs, but may also cause system efficiency to decline due to improper maintenance. Secondly, although traditional sprinkler systems can reduce dust in the air to a certain extent, the uneven coverage of water mist often leads to incomplete dust treatment in some areas, and the treatment and collection efficiency of the treated coal dust is low, which is prone to secondary pollution. These problems indicate that a more efficient and automated solution is needed to improve air quality and dust control in mines. Utility Model Content
