Description
Technical field
The present invention relates to a kind of dust arrester, specially colliery horizontal tunneling boring high effect dust cleaner.
Background technology
Along with the adjustment of country's production capacity policy, be currently in production status is all to use large-scale mechanized equipment, elder generation
The technology entered and the highly efficient and productive Modern Pit of management, but along with each links such as the production of mine, digging, supporting, transports
All produce substantial amounts of dust.Not only endanger the healthy of staff, make staff be susceptible to suffer from colliery occupation disease (as pneumoconiosis,
Pneumosilicosis), it is also easy to cause dust explosion accident, has a strong impact on the safety in production of underground coal mine.At present, in order to reduce underground coal mine
Coal dust and the content of dust, mine traditionally more uses atomizing de-dusting measure, mainly installs straight-bar type or arch in tunnel
The tunneling boring sprayer unit of formula, some mines increase by one nylon wire on the basis of the above, floating coal dust absorption are sprayed at
Nylon wire.The water smoke of sprayer unit ejection is combined with coal dust and dust, forms water droplet and falls, having reached the purpose of dedusting.But
It is, whether straight-bar type sprayer unit or arch formula sprayer unit that it uses under the difference support form of tunnel and is all limited
System, both sprayer units can only spray in the same direction, there is sprinkling dead angle, does not reaches tunneling boring atomization, therefore dedusting effect
The most limited, but due to tradition, dust suppression dust removing effects is the best, wind speed is relatively in fully-mechanized mining working air return way or main return airway
High factor, the regional dust concentration such as fully-mechanized mining working air return way, main return airway is the highest, therefore needs further dedusting.
Basic technical scheme: the first be in mine return air stream according to roadway shape in the suitable position in top, tunnel or bottom
Put 6 points of seamless steel pipes of employing and make straight-bar type or arch formula spray boom frame structure, spray boom is pressed 600mm to 700mm interval all
Even layout high-pressure water nozzle, uses high-pressure hose to be connected with the high-pressure water pipe in tunnel, by shower nozzle by water under high pressure by spray boom
It is sprayed into mist dress, dust moistening in the return of tunnel is increased its gravity to reach dust removing effects.
Installation site: be generally used in the tunnel that wind speed is less.At digging laneway away from work surface 50m, away from tunnel return air
Mouthful 50m, under whitewashing point, first group of tunneling boring spraying is installed in distinguished and admirable 15m position, for ensureing that dust removing effects increases every 200m again
Add one group.
Installation requirement: tunneling boring spray nozzle 600-700mm windward arranges a high-pressure nozzle, nozzle short circuit length
100mm, switch is located at pedestrian side, and water curtain length is not less than lanewidth 90%, and water curtain makees clamp, away from top board with 3mm band iron with holes
The height being not more than 300mm is fixed.Whitewashing tunnel nailing or setscrew are fixed with top board, at tunnel and roofbolt
Fixing.
The second is on the basis of the first, with the wind flow path direction away from spray boom 100-300mm position separately according to tunnel
Shape makes framework and lays nylon fine-meshed screen thereon, falls to forming water on nylon wire at its anterior shower nozzle ejection high-pressure water mist
Mist mould, by water smoke mould moistening and the distinguished and admirable middle dust of stop, to reach dust removing effects.
The air-flow velocity that both technology only adapt to is less than or equal to 2.0m/s, and range of application is limited.Efficiency of dust collection is low, through surveying
Fixed full dirt efficiency of dust collection is only 23%, exhales the efficiency of dust collection of dirt to be only 20%.Need to install many groups to use simultaneously, cause water under high pressure
A large amount of wastes, increase pumping equipment.Dead angle is sprayed to exist bottom up to top board, and tunnel, it is impossible to realize complete disconnected at spray boom
Face dedusting.Frame stability is poor, fragile.
Summary of the invention
For above-mentioned technical problem, the present invention provides the colliery horizontal tunneling boring high-effective dust-removing dress that a kind of efficiency of dust collection is high
Put.
Colliery horizontal tunneling boring high effect dust cleaner, including two-stage abnormity horizontal demister, the thickest level is different
Shape horizontal demister and essence level abnormity horizontal demister；Every grade of special-shaped horizontal demister includes organizing more pacifies side by side
The special-shaped dedusting blade of dress；Before and after thick level abnormity horizontal demister, end is respectively mounted tunneling boring aerosol apparatus, essence level abnormity
Horizontal demister rear end is provided with tunneling boring aerosol apparatus；The side of described every grade special-shaped horizontal demister is also installed
There is water leg.
Described special-shaped dedusting blade is " entering " word shape, and including the primary blades of arc, the top of arc primary blades has down
Hook is curved, and described barb is curved towards air intake direction.
Tunneling boring is set according to drift section and is arranged side by side smooth surface polymorphic structure thing to change wind direction increasing comprehensively
Add dust-contained airflow and plume contact time, promote dust-laden water smoke effectively to touch with polymorphic structure thing by dust-laden self wind-force distinguished and admirable
Hitting, dust-laden droplet collides with abnormity dedusting blade and is attached in its surface.The self gravitation utilizing dust-laden droplet settles
Make drop increasing with the surface tension of the abnormity rubbing action of dedusting blade, adsorption and liquid, until gather
Drop arrives greatly the gravity himself produced and exceedes climbing power and when the making a concerted effort of surface tension of liquid of gas, and dust-laden drop is just from different
Separated on shape dedusting blade surface, thus improve efficiency of dust collection, realized mechanical type dedusting with this.
The size of blade pitgh, has a significant impact the demisting efficiency of demister.Along with the increase of blade pitgh is except mist effect
Rate reduces.Preferably between blade pitgh 25-40mm.
The increase of abnormity horizontal demister progression, efficiency of dust collection increases, and the pressure loss increases the most therewith.Demister
Design require with improve demisting efficiency reduce the pressure loss as objective.Therefore, pursue demisting efficiency merely and increase progression, but
Ignoring the increase of gas-flow resistance loss, the loss making energy is dramatically increased by its result.Optimal design uses two-stage dust arrester.
Tunneling boring aerosol apparatus hydraulic pressure is typically based on the distance between the feature of flooding nozzle and abnormity horizontal demister
Determining etc. factor, the distance between nozzle and abnormity horizontal demister is generally 650-900mm, when flushing water forces down, and punching
Wash weak effect.Washing pressure height then easily causes smoke secondary band water.Reduction blade service life simultaneously.
The colliery horizontal tunneling boring high effect dust cleaner that the present invention provides, is greatly improved efficiency of dust collection, by complete in tunnel
Dirt efficiency of dust collection to 55%, will be exhaled the efficiency of dust collection of dirt by tunneling boring spraying 20% raising extremely by tunneling boring spraying 23% raising
60%, it is respectively increased 140%, 200%, it is achieved tunneling boring dedusting, without dead angle and improve sprayer unit stability, structure is steady
Fixed, it is difficult to collapse.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
