Abstract
The utility model discloses a non-power low-noise negative-pressure wet type dust removing device, which comprises a fresh air pipe which is arranged horizontally in the roadway head direction; the air pipe extends to a tunneling machine; the rear part of the tunneling machine is provided with a dust removing pipe which is connected with the roadway outlet; and one end of the dust removing pipe close to the tunneling machine is fixedly provided with a spraying head which faces the roadway outlet and is used for spraying the water mist. The utility model requires no additional power; the energy of the compressed air existing in the roadway can atomize the water source; and negative pressure can be generated at the inlet of the airflow collection shield to effectively guide and collect the dust airflow for dust removal. The utility model has the advantages of simple and compact structure, low noise and good dust removing effect, and is applicable to the field use.
Description
Technical field:
The utility model relates to a kind of wet dust removal device, the development works face that specifically a kind of dust that can produce the mining excavation work plane or dust are concentrated carry out unpowered low noise wet dust removal device effective dedusting, that need not power, the negative pressure form, belongs to the matching used cleaner of mining excavation work plane.
Background technology:
Dust is one of main natural calamity in down-hole, mine, along with improving constantly of mine machinery level, the generation of mine dust is increasing, wherein getting working face is to produce the maximum place of dust source, effectively dedusting, reduce the concentration of dust in the air stream, all play an important role for mine safety production and staff's physical and mental health.In the application of present dedusting technology, the application of equipment such as venturi scrubber, sack cleaner, auto-excitation type wet scrubber and electrostatic precipitator is arranged, but these equipment manufacturing cost height, volume are big, and all belong to dynamic device, can not obtain extensive, stable, use reliably at the scene, the scene usually be the substitute is direct employing spraying and is spread the water dirt mode of going out, and the shortcoming of this mode is that water supply volume is big, poor, the environment mire of dust removing effects.
The utility model content:
For overcoming the defective of prior art, the purpose of this utility model be to provide a kind of simple and easy to do, need not to add again power, can utilize shower nozzle to produce the device that negative pressure guiding dust-contained airflow carries out effective dedusting automatically, this device volume is little, in light weight, cost is low, installs easily, safeguards simple.
The utility model technical solution problem adopts following technical scheme:
Unpowered low noise negative pressure wet dust removal device, comprise towards the fresh distinguished and admirable ajutage of tunnelling direction horizontal arrangement, ajutage extends to the development machine place, establish a dust removing tube that leads to the tunnel outlet at the development machine rear, and in dust removing tube, set firmly one near an end of development machine can be towards the fog-spray nozzle of tunnel Way out water spray.
Removably be connected with a dust air-flow collecting hood at dust removing tube towards an end of development machine.
Described fog-spray nozzle by a tee piece respectively be arranged in the tunnel in water pipe and pressure ventilation pipe be communicated with, the junction of water pipe and tee piece is provided with control valve, the junction of pressure ventilation pipe and tee piece is provided with AFS.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model leads to the dust removing tube that the tunnel exports by establish one in the tunnel at development machine rear, dust removing tube connects a dust air-flow collecting hood at the end near development machine, and the end near development machine sets firmly a fog-spray nozzle in dust removing tube, fog-spray nozzle is communicated with by existing water pipe in tee piece and the tunnel and pressure ventilation pipe, can be towards tunnel Way out water spray, can produce negative pressure in air-flow collecting hood entrance, therefore can effectively guide and collect the dust air-flow carries out dedusting.
2, be provided with control valve in the junction of water pipe and tee piece, the junction of pressure ventilation pipe and tee piece is provided with AFS, can regulate the intensity of water smoke that fog-spray nozzle sprays, and contains different Dust Capacities in the dust air-flow so that be suitable for.
3, the utility model does not need to add new power again, utilizes in the tunnel existing pressure wind energy atomizing water source and can produce negative pressure in air-flow collecting hood entrance, effectively guides and collects the dust air-flow and carry out dedusting, simple and compact for structure, noise is little, and good dedusting effect is highly suitable for on-the-spot the use.
Description of drawings:
Fig. 1 is structure of the present utility model and working state figure.
Figure 1A is the right view of Fig. 1.
Fig. 2 is an A portion enlarged drawing among Fig. 1.
Number in the figure: 1 development machine, 2 ajutages, 3 dust removing tubes, 4 fog-spray nozzles, 5 tee pieces, 6 water pipes, 61 control valves, 7 pressure ventilation pipes, 71 AFSs, 8 air-flow collecting hoods.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment, non-limiting examples is as described below:
Shown in embodiment: Fig. 1, Figure 1A, when development machine 1 is worked in the tunnel, driving face can produce a large amount of dust, towards tunnelling direction horizontal arrangement fresh distinguished and admirable ajutage 2 is being arranged, ajutage 2 extends to development machine 1 place, the exit foldback of dust towards the tunnel can be polluted to reduce in order to collect and discharge dust, establish one at the rear of development machine 1 and lead to the dust removing tube 3 that the tunnel exports, and the end near development machine sets firmly a fog-spray nozzle 4 in dust removing tube.Shown in Figure 2, fog-spray nozzle 4 is communicated with original water pipe 6 and pressure ventilation pipe 7 that is arranged in the tunnel respectively by a tee piece 5, and the junction of water pipe and tee piece is provided with control valve 61, the flow of adjustable water saving; Pressure ventilation pipe 7 is provided with AFS 71 with the junction of tee piece, adjustable solar term stream flow velocity, and with the water atomization that flows in the fog-spray nozzle, the direction water spray that fog-spray nozzle exports towards the tunnel in dust removing tube.Discharge for the dust of collection work face substantially and by dust removing tube, removably be connected with a dust air-flow collecting hood 8 towards an end of development machine 1, in the concrete operations, can adopt to be threaded or other connectors connect at dust removing tube 3.Because of fog-spray nozzle 4 towards tunnel Way out spraying, can produce negative pressure in air-flow collecting hood entrance, therefore can effectively guide and collect the dust air-flow and enter and carry out nebulization dust in the dust removing tube.When specifically being provided with, ajutage 2 and dust removing tube 3 can be lifted on the tunnel inner roof wall or connect firmly on the sidewall of tunnel, and the port of export of dust removing tube should downward-sloping slightly installation, and in its exit the dust water collection pipe are set, and dust water is drained into other places.The utility model does not need to add new power again, utilize in the tunnel existing pressure wind energy atomizing water source and can produce negative pressure in air-flow collecting hood entrance, effectively guiding and collection dust air-flow carry out dedusting, the utility model is simple and compact for structure, noise is little, good dedusting effect is highly suitable for on-the-spot the use.Really, the conspicuous change that the utility model is done all should fall within the protection domain of the present utility model.
