Wet vibrating string curtain type dust extraction fan used in coal mine and application method thereof

Abstract

The invention discloses a wet vibrating string curtain type dust extraction fan used in a coal mine and an application method thereof. The fan is characterized in that spray heads are arranged at the four sides of an air channel of a drawer-type anti-explosion ventilator; a section of air drum is connected at the outlet of the air channel; a sprinkler head and a vibrating string curtain are arranged inside the air drum; the sprinkler head sprinkles towards the vibrating string curtain; and a drain outlet is arranged below the outlet of the air drum. The vibrating string curtain is formed in such a manner that vertically strained steel strings are distributed on a frame. The application method of the fan includes the steps that a pressurized water pipe is connected with the spray heads and the sprinkler head through quick connectors; when dusty air passes through the air channel, the dust is wetted by mist spray and is attached, detained and captured on the vibrating string curtain; the captured dust on the vibrating string curtain falls off under the vibration generated by air impact and is flushed by water spray; and finally the dust mixture is discharged from the drain outlet along with the water flow under the action of dead load. According to the wet vibrating string curtain type dust extraction fan, the dust concentration in the tunneling process can be greatly reduced, the dust intake volume of the underhole operators is reduced, the operating environment is improved, the visual range and the visibility of the operators are increased and the safety in the tunneling operation is enhanced.

Description

technical field [0001] The invention relates to a dedusting device used for the bolt-shotcrete working face of tunneling underground in a coal mine. Background technique [0002] Coal mining face will produce a lot of dust during the production process, high concentration of dust permeates and accumulates, long-term inhalation of dust on the mining face in this working environment makes coal miners prone to coal silicosis, especially in the direct excavation face Workers are more susceptible to coal silicosis. Mining dust is also the culprit that affects safe production. The coal dust accumulated in the mining process is prone to fire or explosion, which seriously threatens the life safety of underground workers. The existing dust removal equipment is mainly to install a water supply spray system on the working face, but the dust removal effect is not good, and the water mist that captures the dust still permeates the working face, polluting the air.
