The invention discloses a
coal mine dust removal
system and dust removal method. The
coal mine dust removal
system comprises a
trapping device, a pneumatic suction device, an entrainment dust removaldevice, a
cyclone separation device, a multi-phase flow division device and a dust exhauster which are connected in sequence, wherein the
trapping device, the pneumatic suction device, the entrainmentdust removal device, the
cyclone separation device and the multi-phase flow division device are all of tubular structures, every two adjacent devices are integrally connected through a
flange, and the pneumatic suction device is connected with a
coal mine ventilation
pipe through a telescopic hose; a
slag discharge port of the multi-phase flow division device is connected with a coal mine
slag discharge system through a telescopic pipeline, the entrainment dust removal device is connected with a coal mine
water supply system through a hose, and stop valves are arranged on the telescopic hoseand a pipeline of the hose. The
coal mine dust removal system is reasonable in unit combination design and small in size, and has the advantages of being small in investment, small in occupied area, low in
energy consumption, high in dust removal rate and the like, and the
coal mine dust removal method has the advantages of being short in process, low in operation cost and the like.
