Description
Technical field
The invention belongs to pit gear field, be specifically related to the efficient coaxial air curtain dust pelletizing system in a kind of colliery.
Background technology
Major part coal seam, all away from earth's surface, therefore cannot use opencast mode.Underground mining accounts for 60% of world's coal production.In pit, usually use room-and-pillar method to advance in coal seam, beam column is used for supporting pit.But in coal mining process, the mine often degree of depth reaches hundreds of rice and even goes up km, the inside foreign flavour content is low, and toxic gas content is many, therefore need to blast fresh air in mine, and the toxic gas of discharging in mine and dust, the high-power dedusting fan of the many employings of existing mine dedusting uses air duct exhausting to carry out dedusting and air-supply, often use the dedusting fan of 45KW*2, but need the power of blower fan larger, cost of use is higher, and can negative pressuren zone be formed in air duct end, often dedusting cannot be carried out in negative pressuren zone, cause dust removing effects poor, and the dust of operating surface can be dispersed and holds, cause operating surface dust larger, affect the healthy of workman.
Summary of the invention
The object of this invention is to provide the efficient coaxial air curtain dust pelletizing system in a kind of colliery, by changing the design of dust pelletizing system, improve the efficiency of dedusting, and greatly can save the energy.
The present invention is achieved through the following technical solutions:
The efficient coaxial air curtain dust pelletizing system in a kind of colliery, comprise interior air duct and outer air duct, interior air duct is flare openings, one end that interior air duct diameter is less is concentric with outer air duct, be socketed in outer air duct non-contiguously, interior air duct one end be socketed in outer air duct is closed, the internal diameter of outer air duct be greater than interior air duct diameter compared with small end diameter, be less than the diameter of the larger end of interior air duct diameter, be provided with pressure fan in outer air duct, interior air duct sidewall is provided with discharge pipe, is provided with induced draft fan in discharge pipe.
Preferably, high-frequency vibration sieve plate and liquid distribution is provided with in discharge pipe.
Preferably, one end closed by interior air duct is taper concave surface.
Preferably, high-frequency vibration sieve plate is other is provided with the pneumatic positive hammerhead that can knock high-frequency vibration sieve plate and the giant that can rinse high-frequency vibration sieve plate.
Exogenous wind inside pipe wall is spirality air channel structure.
Beneficial effect of the present invention: dust pelletizing system provided by the invention by being connected non-contiguously between interior air duct with outer air duct, pressure fan is used inwardly to press wind by outer air duct, fresh air is pressed to interior air duct, it is closed that interior air duct and exogenous wind socket joint touch one end, air can be made to flow along interior air duct outer wall, due to the stop of the horn-like structure of interior air duct, air curtain is formed at horn mouth place, isolated inside and outside air, the dust of operating surface and air and the external world are separated, prevent dust recycling, simultaneously, discharge pipe is provided with at interior air duct sidewall, induced draft fan is provided with in discharge pipe, the dust of getting working face and toxic gas can be extracted out by induced draft fan, and by high-frequency vibration sieve plate and liquid distribution, dust is become mud eliminating, pernicious gas is directly got rid of, the present invention is by this design, work plane in coal mine roadway and operating surface can be separated, dust is made to pollute operating surface, simultaneously, dust removing effects is than directly using induced draft fan good dedusting effect, and only need power to be that namely the dedusting fan of 28-30kw can reach dust removing effects, energy-saving effect is given prominence to, dust pelletizing system provided by the invention can save electricity 200-300KW.h every day, efficiency of dust collection improves more than 35%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the present invention's wind direction schematic diagram when working.
Detailed description of the invention
The efficient coaxial air curtain dust pelletizing system in a kind of colliery, comprise interior air duct 3 and outer air duct 2, interior air duct 3 is flare openings, one end that interior air duct 3 diameter is less is concentric with outer air duct 2, be socketed in outer air duct 2 non-contiguously, interior air duct 3 one end be socketed in outer air duct is closed, the internal diameter of outer air duct 2 be greater than interior air duct diameter compared with small end diameter, be less than the diameter of the larger end of interior air duct diameter, pressure fan 1 is provided with in outer air duct 2, interior air duct 3 sidewall is provided with discharge pipe 8, is provided with induced draft fan 5 in discharge pipe 8.
Preferably, in the present invention air duct 3 for one end be cylindric airduct, the other end is horn opening, and cylindric airduct end is enclosed construction, and interior air duct blind end is connected with one heart, non-contiguously with outer air duct 2, and the sidewall of cylindric airduct is provided with discharge pipe 8.
Preferably, be provided with high-frequency vibration sieve plate 7 and liquid distribution 9 in discharge pipe 8, liquid distribution 9 forms water curtain and is combined with dust, high-frequency vibration sieve plate 7 is by vibrations, the contact of dust and water can be increased, promote that dust is combined with water and form mud and discharge, prevent formation dust pollution.
Preferably, one end closed by interior air duct is taper concave surface 11, the wind that pressure fan in outer air duct is compressed into can be stopped, the annular air that wind is formed along interior air duct and exogenous wind cylinder equably flows, by the stop of the horn-like port 4 of interior air duct, form the uniform air curtain of blast, work plane and operating surface are isolated, form good clean working environment.
Preferably, high-frequency vibration sieve plate 7 is other is provided with the pneumatic positive hammerhead 10 that can knock high-frequency vibration sieve plate 7 and the giant 6 that can rinse high-frequency vibration sieve plate; Can prevent mud from blocking screen cloth, oscillating screen plate can be used continuously, reduce the cost that screen cloth is changed and used.
Preferably, exogenous wind inside pipe wall is helical structure, and during pressure fan 1 air intake, wind is airduct 2 internal spiral air intake outside, air intake evenly, the air curtain of formation cuts off the better effects if of inner air and outer air.
In use, use is placed facing to getting working face in dust pelletizing system horn mouth side.
