Cross in coal breakage pipeline deflector chute, air-flow can be produced when falling on deflector chute and brings substantial amounts of dust, the dust of coal spout rear end passes through
Electrostatic adhesive tape in electrostatic sealing curtain absorbs a part, in the dust cleaning case for reaching mist dust remover, by cone screen plate, shower nozzle spray
The water smoke gone out is merged with dust to be dropped in deflector chute, and the dust of coal spout front end is by one-level decompression cabinet pressure relief flow to one-level
Merged in mist dust remover on decompression cabinet with water smoke, form water droplet and drop in deflector chute, air-flow is discharged from dust outlet tube, it is remaining
Part dust flow in second depressurized case, merged by the mist dust remover on second depressurized case with water smoke, formed water droplet
Drop in deflector chute, air-flow is discharged from dust outlet tube.
Beneficial effect：
1. the present invention is a kind of water mist dust fall material guide device and dust-removing method, small investment, effect are good, significantly improve the work of workman
Industry environment, protects workman's healthy, improves labour productive forces, reduces the pollution of dust plant area surrounding environment.
The present invention uses decompressor, using pressure balance and opens circulating current system and reduces powder in coal conductance pipe to greatest extent
The pressure of dirt air, is allowed to tend to balance with exterior space pressure, and the malleation that dust air is produced when fire coal falls is obtained in time
Eliminate.
Water mist dust fall material guide device of the present invention coordinates with electrostatic resistance dirt sealing curtain, has prevented flour dust overflow, has polluted environment
The phenomenon and mean dust concentration improved at coal-fired dust recovery utilization rate, deflector chute in air is substantially reduced, so as to reach
Below the labour hygiene standard 1Omg/m of country.
Present invention investment is small, aims at only Water-fog dusting apparatus and the decompression cabinet of dust guard construction.
The electrostatic dust-break curtain of the present invention can will be separated into multiple chambers and play a part of classification decompression inside deflector chute.
The present invention, which is not required to extra power set, just can reach dust removing effects, save the energy.
Present invention saves the power consumption of deduster deashing devices and frequent plant maintenance expense, the water in economy effect
Mist dedusting superiority is obvious.
Brief description of the drawings：
Accompanying drawing 1 is the structural representation of the present invention.
Accompanying drawing 2 is the structural representation of the mist dust remover of the present invention.
Accompanying drawing 3 is the structural representation of the electrostatic sealing curtain of the present invention.
