Description

Water mist dust fall material guide device
Technical field:
A kind of coal handling system technical field is the utility model is related to, is specifically related to a kind of water mist dust fall material guide device.
Background technology:
Steam power plant uses coal-burning boiler, needs the substantial amounts of coal that burns every year, coal from entering factory to before entering boiler combustion, To pass through a series of transports and process these processes can all produce substantial amounts of coal dust, the closed of installation, ventilation, dedusting The enclosed hood ventilation duct ventilation blowers of system and the annex of correlation, amounting to needs million yuan of investments to solve deflector chute leakage powder phenomenon, The efficiency of dedusting is low, takes a substantial amount of time, and several layers of mouth masks etc. are worn during worker's operation and are difficult to stop that dust enters human body, powder The pollution of dirt not only the health of operating personnel is constituted a serious threat and also influence labor productivity.
Utility model content:
The purpose of this utility model is that solve the shortcomings that substantial amounts of coal dust and leakage powder, there is provided a kind of simple, efficient Water mist dust fall material guide device.
Above-mentioned purpose is realized by following technical scheme:
A kind of water mist dust fall material guide device, its composition include:Deflector chute, multiple coal breakages dresses are installed on described deflector chute Put, the left end of each described Coal Cake Falling Device is fitted with decompressor, between multiple described Coal Cake Falling Devices and multiple described The both ends of Coal Cake Falling Device be fitted with electrostatic sealing curtain, the right-hand member of described deflector chute is provided with mist dust remover, described Decompressor is made up of one-level decompression cabinet, second depressurized case and two decompression cabinet mist dust removers, described second depressurized case On described one-level decompression cabinet, the decompression cabinet mist dust remover described in two is separately mounted to described one-level decompression cabinet On described second depressurized case.
Described water mist dust fall material guide device, described water mist dust fall device and described decompression cabinet water mist dust fall device all include Depositing dust case, shower nozzle, cone screen plate is sequentially installed with from top to bottom in described depositing dust case, the upper end of described depositing dust case is provided with Dust outlet tube.
Described water mist dust fall material guide device, described Coal Cake Falling Device are made up of coal breakage bucket and coal spout, described coal breakage Pipe is arranged on the lower end of described coal breakage bucket.
Described water mist dust fall material guide device, described electrostatic sealing curtain is made up of fixed bin and multiple electrostatic adhesive tape, more Individual described electrostatic adhesive tape is arranged on the lower end of described fixed bin.
Beneficial effect:
1. operation principle of the present utility model is:Coal dust passes through in coal breakage pipeline deflector chute from coal breakage bucket first, falls on and leads Air-flow can be produced during hopper and brings substantial amounts of dust, the dust of coal spout rear end absorbs by the electrostatic adhesive tape in electrostatic sealing curtain A part, reach in the dust cleaning case of mist dust remover, by cone screen plate, the water smoke of shower nozzle ejection merges to drop to dust leads In hopper, the dust of coal spout front end passes through in the mist dust remover in one-level decompression cabinet pressure relief flow to one-level decompression cabinet and water Mist is merged, and forms water droplet and drops in deflector chute, and air-flow is discharged from dust outlet tube, and remaining part dust flow to second depressurized case It is interior, merged by the mist dust remover on second depressurized case with water smoke, form water droplet and drop in deflector chute, air-flow is from dust outlet tube Discharge.
The utility model is a kind of water mist dust fall material guide device and dust-removing method, and small investment, effect are good, significantly improve work The operating environment of people, the health of worker is protected, improve labour productive forces, reduce the dirt of dust plant area surrounding environment Dye.
The utility model uses decompressor, using pressure balance and opens circulating current system and reduces coal conductance pipe to greatest extent The pressure of interior dust air, it is allowed to tend to balance with exterior space pressure, malleation caused by dust air obtains when fire coal falls Eliminate in time.
The utility model water mist dust fall material guide device coordinates with electrostatic resistance dirt sealing curtain, has prevented flour dust overflow, pollution ring The phenomenon in border simultaneously improves coal-fired dust recovery utilization rate, and the mean dust concentration at deflector chute in air substantially reduces, so as to Below the labour hygiene standard 1Omg/m of country is reached.
The utility model investment is small, aims at only Water-fog dusting apparatus and the decompression cabinet of dust guard construction.
Electrostatic dust-break curtain of the present utility model can by be separated into inside deflector chute multiple chambers play classification decompression work With.
The utility model, which is not required to extra power set, just can reach dust removing effects, save the energy.
The utility model saves the power consumption of deduster deashing devices and frequent plant maintenance expense, is imitated in economy Upper water mist dust-removing superiority is obvious.
Brief description of the drawings:
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of mist dust remover of the present utility model.
Accompanying drawing 3 is the structural representation of electrostatic sealing curtain of the present utility model.
