Underground Intelligent Dry Dust Collector in the Coal Mine

Aiming at the problems of low dust removal efficiency, poor removal of respiratory dust, and serious waste of water resource, caused by underground wet dust removal device in heading face in the coal mine, and the promotion of coal mine mechanization, informatization, automation, and intelligent construction, we make the development of an intelligent dry dust collector working underground. We adopt new production process to develop the flame-retardant anti-static dust removal filter material without rolling points, which can increase the effective dust removal filter area by more than 20%, greatly reduce the size of the dust collector, and have a total dust removal efficiency of more than 99.5%. We apply automatic intelligent control technology to realize linkage with heading machine, automatic start and stop, intelligent cleaning, fault detection and alarm, and unmanned operation, and to support multiple terminal equipment access, so as to provide complete set of dry dust removal technical support for unmanned dig working face.
