The invention discloses a method and a system for negative pressure-induced dust removal. The method comprises that: an atomization plant capable of generating water fog is arranged in a mine roadway,and a plurality of spraying points are arranged according to a temperature and humidity in the mine; the atomization plant comprises a pump station, an air compressor and a plurality of spraying assemblies; and when the atomization plant is used, the coal dust is wetted in advance, the water fog is atomized twice and then rotatably sprayed, and the wetted coal dust is sucked in a dust removing fan, purified by the dust removing fan and then discharged in a mode of slurry water. Compared with the conventional wet type dust removing method, the device of the invention has the advantages of highdust removal efficiency, less water consumption and reliable performance and can more effectively prevent and remove dust in all environments of the coal preparation plant with few influences on coalquality.
Description
technical field [0001] The utility model relates to a mine dust removal method, in particular to a negative pressure induced dust removal method. Background technique [0002] Coal preparation dust control has always been one of the important research topics of coal mine safety. As we all know, wet dedusting is the most common method used in coal preparation plants. Water can moisten the dust, increase the gravity of the dust particles, and aggregate the fine dust particles into larger dust particles, so that the floating dust can accelerate the settlement, and the falling dust is not easy to fly. [0003] However, the traditional wet dust removal method is to spray pressure water on the dust point in the form of a jet through the nozzle. This method does not consider the impact of wind field, temperature and humidity changes on dust, the atomization effect is poor, the range of action is small, the nozzle is easy to block, and the quality of coal is affected due to the la...
