Integral dust falling and purification device applied to underground coal mine

Abstract

The invention discloses an integral dust falling and purification device applied to an underground coal mine and belongs to the technical field of gas purification. The integral dust falling and purification device comprises a dust falling and purification pipe, a dust falling and purification device, an activated carbon purification plate, a negative pressure fan set and a water curtain dust falling device, wherein the dust falling and purification device is installed at the center inside the dust falling and purification pipe; the activated carbon purification plate and the negative pressurefan set are successively installed on one side of the dust falling and purification device; and the water curtain dust falling device is installed on the end, close to the negative pressure fan set,of the dust falling and purification pipe. The device disclosed by the invention is scientific and rational and safe and convenient in use; the device greatly increases a use rate of a filtering mesh;meanwhile, dust falling and purification effects of coal dust in air are ensured; the coal dust can be scrapped automatically after filtration; efficiency is higher; and effects are better

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to an integrated dust reduction and purification device for underground coal mines. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. The mining of underground coal mines needs to be carried out underground in coal mines. Coal mines are the general term for the wells, chambers, equipment, ground buildings and structures that form the underground coal mine production system. In a confined space, the air does not circulate, and a large amount of coal dust will be generated during the coal mining process, which will endanger the lives of mining workers. In the prior art, the coal dust generated during coal mining is reduced by spraying water during the coal mining process. Or use the dust filter plate to filter the coal dust gene...

The mining of underground coal mines needs to be carried out underground in coal mines. Coal mines are the general term for the wells, chambers, equipment, ground buildings and structures that form the underground coal mine production system. In a confined space, the air does not circulate, and a large amount of coal dust will be generated during the coal mining process, which will endanger the life safety of the mining workers. In the prior art, the coal dust generated during coal mining is reduced by spraying water during the coal mining process. Or use the dust filter plate to filter the coal dust generated in the mining process to achieve the effect of air purification, but there are certain defects:

[0003] The dust filter plate can only use a single-sided dust filter plate to filter coal dust, which reduces the utilization rate of the dust filter plate. At the same time, it is impossible to scrape off the coal dust on the dust filter plate in time, which will also affect the dust filter. The filter effect of the plate reduces the purification effect of the air in the coal mine;
