Description
Technical field
The utility model relates to a kind of drilling dust-removing apparatus, particularly relates to the explosion-proof dust arrester of a kind of boring.
Background technology
A large amount of dust is produced in coal mine gas extraction borehole row powder work progress, this airborne dust not only brings illness to constructor, and be the accident potential of coal-dust explosion and burning, existing drilling dust-removing apparatus generally all provides power by motor, meet fire when the volume fraction of gas in confined space reaches 5% to 15% can blast, and motor can produce spark when loose contact, existing drilling dust-removing apparatus is made to there is potential safety hazard, make the poor reliability of existing drilling dust-removing apparatus work, and existing drilling dust-removing apparatus water consumption is large.
Utility model content
The purpose of this utility model is just to provide a kind of boring explosion-proof dust arrester to solve the problem.
In order to achieve the above object, the utility model have employed following technical scheme:
The explosion-proof dust arrester of a kind of boring, comprise air inlet pipe, sewage draining exit, outlet, receiving tube, elementary dust-fall pipe, air compressor machine, gas outlet, gas nozzle, choke valve and vacuum tank, the air outlet of described air compressor machine is connected by the entrance of pipeline with described vacuum tank, pipeline between described air compressor machine and described vacuum tank is provided with reducing valve, the outlet of described vacuum tank is connected with described gas nozzle by pipeline, described gas nozzle is positioned at described elementary dust-fall pipe, the gas outlet of described gas nozzle is positioned at the described elementary dust-fall pipe of described receiving tube side, described gas outlet is arranged on the side of described outlet, described sewage outfalls setting is in the bottom of described outlet, hydraulic spray nozzle is equipped with in described air inlet pipe and described mixing tube.
In said structure, pneumatics function compressed air is as power of the present utility model, make the utility model in use, not by the restriction of the volume fraction of gas, the utility model is made to there is not potential safety hazard, course of work safety and reliability, from the gases at high pressure of gas nozzle ejection, make the faster of dirt air-flow process, thus in the unit interval of the present utility model except dust quantity larger, the water consumption of the dirt gas of same volume is less.
Particularly, described hydraulic spray nozzle is connected with one end of water inlet pipe, and described water inlet pipe is provided with choke valve, is provided with multiple waterfog head in described mixing tube.
More specifically, the described waterfog head in described mixing tube is at least four.
The beneficial effects of the utility model are:
The utility model is power by air compressor machine compressed air, not containing other electric elements, in use, not by the restriction of the volume fraction of gas, the utility model is made to there is not potential safety hazard, course of work safety and reliability, the gases at high pressure that the utility model sprays from gas nozzle, make the faster of dirt air-flow process, thus in the unit interval of the present utility model except dust quantity larger, the water consumption of the dirt gas of same volume is less.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of explosion-proof dust arrester of holing of the utility model.
In figure: 1-waterfog head, 2-air inlet pipe, 3-reducing valve, 4-air compressor machine, 5-gas outlet, 6-sewage draining exit, 7-outlet, 8-diffuser pipe, 9-mixing tube, 10-receiving tube, 11-gas nozzle, the elementary dust-fall pipe of 12-, 13-choke valve, 15-vacuum tank.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the explosion-proof dust arrester of the utility model one boring, comprise air inlet pipe 2, sewage draining exit 6, outlet 7, receiving tube 10, elementary dust-fall pipe 12, air compressor machine 4, gas outlet 5, gas nozzle 11, choke valve 13 and vacuum tank 15, the air outlet of air compressor machine 4 is connected by the entrance of pipeline with vacuum tank 15, pipeline between air compressor machine 4 and vacuum tank 15 is provided with reducing valve 3, the outlet of vacuum tank 15 is connected with gas nozzle 11 by pipeline, gas nozzle 11 is positioned at elementary dust-fall pipe 12, the gas outlet 5 of gas nozzle 11 is positioned at the elementary dust-fall pipe 12 of receiving tube 10 side, gas outlet 5 is arranged on the side of outlet 7, sewage draining exit 6 is arranged on the bottom of outlet 7, waterfog head 1 is equipped with in air inlet pipe 2 and mixing tube 9, waterfog head 1 is connected with one end of water inlet pipe, and water inlet pipe is provided with choke valve 13, is provided with multiple waterfog head 1 in mixing tube 9, waterfog head 1 in mixing tube 9 is at least four.
The utility model principle is as follows:
Dust-contained airflow enters the utility model from air inlet pipe 2, droplet is formed after the water smoke and dust-contained airflow combination of waterfog head 1 ejection in elementary dust-fall pipe 12, air is sprayed at a high speed by gas nozzle 11 after air compressor machine 4 compresses after vacuum tank 15, high velocity air drives droplet and does not enter mixing tube 9 with the dirt gas of water smoke combination by receiving tube 10, the water smoke that waterfog head 1 in mixing tube 9 sprays, the dirt gas do not combined with water smoke is fully combined with water smoke, enter diffuser pipe 8 to underspeed the laggard inlet/outlet pipe 7 of raised pressure, gas is discharged by gas outlet 5, sewage is formed in conjunction with the dust in the dirt air-flow of fog and grit, discharge from sewage draining exit 6, water atomization amount is controlled by the choke valve 13 on water inlet pipe, the droplet changed into by water smoke, be dispersed in dust-contained airflow and enter mixing tube 9 and diffuser pipe 8 together with dust-contained airflow, height of formation turbulence state in the dust-contained airflow of high velocity air and suction and the flow process of droplet in mixing tube 9, the chance of continuous contact and crash is created to grit and droplet, grit is caused to be trapped by droplet, reach the effect of dedusting, fog is depressed with dirt closes the sewage formed, discharge from sewage draining exit 6, with after gas discharge from exhaust opening.
