Abstract
The invention discloses a negative-pressure jet spraying dust suppression device which comprises a dust suppression tube and a jet assembly. The dust suppression tube is of a pipeline structure with two through ends, the jet assembly is arranged inside the dust suppression tube and comprises at least one jet sprayer, spraying directions of the jet sprayers are consistent with the axial direction of the dust suppression tube, and the jet sprayers are used for being connected with a high-pressure liquid source to form jets and negative-pressure along the axis of a pipeline. The negative-pressure jet spraying dust suppression device has the advantages the high-pressure jet sprayers are directionally arranged in the dust suppression tube to form a jet system which is used for suppressing dust in drilled holes of underground tunnels of coal mines and is creative application in the industry, the dust can be deposited by the aid of mist liquid (water) sprayed via the sprayers to form fluid mixtures which can be processed conveniently, the jets and the negative-pressure are formed in the dust suppression tube under a jet effect realized by spraying actions of the sprayers, the dust sprayed out of the drilled holes can be continuously sucked into the dust suppression tube by the negative-pressure so as to be processed, and a dust suppression effect is greatly improved.
Description
Technical field
The invention belongs to the coal mining technical field, be particularly related to and utilize the jet flow negative pressure device that the interior gas that sprays of boring in the extraction borehole work progress and pressure wind row powder dust, boring mud etc. are carried out the spraying firing dust processing, to prevent that executing the brill process generation that dust transfinites and makes the construction environment deterioration even cause danger such as dust explosion occurs.
Background technology
Coal mine gas, dust accident are one of great harm of down-hole, if gas, dust accident take place, not only can the heavy damage production environment, and can cause casualties, cause tremendous loss for the people, enterprise, country, therefore, eliminating gas exceeding limit and dust is the precondition of prevention gas, dust accident, also is one of important leverage of mine safety production.
Because geologic sedimentation effect, a large amount of toxic and harmfuls such as gas have been overstock in the coal seam, in order to realize safe digging, generally, at first to arrange special-purpose gas pumping tunnel before the digging, adopt underground drill rig construction extraction borehole to shift to an earlier date mash gas extraction, treat that extraction is up to standard after, can begin digging coal.Yet in construction extraction borehole process, can form a large amount of dust, if these dust without the dirt processing meeting severe exacerbation construction environment of going out, acquire a certain degree back even can't continue construction of dust concentration.If this execute change the line of production dust living this as combustible, the accident that forms after it reaches finite concentration is more serious than gas accident.
In the prior art, usually the way of taking at these serious problems is to seal by a sealing of hole cover to change the hole, make dust few working space that is diffused into of trying one's best, but this processing mode can not reach requirement far away as can be seen from practice, still there is a large amount of dust to be diffused into working space, therefore badly influence working environment, and execute that the drillings dust pollution is serious, construction environment is very abominable, serious threat dust potential safety hazard such as exceed standard.
Summary of the invention
The objective of the invention is the deficiency for potential safety hazards such as solving in the tunnel dust severe exacerbation construction environment that produces in the construction extraction borehole process, cause that dust exceeds standard, proposed the jet flow negative pressure spraying dust firing device.
Technical scheme of the present invention is: the jet flow negative pressure spraying dust firing device, comprise go out dirt pipe and fluidic module, the described dirt pipe that goes out is the pipeline configuration that two ends connect, described fluidic module is arranged at the dirt pipe inside of going out, comprise that injection direction points at least one consistent fluid jet nozzle along the dirt tube axis direction that goes out, described fluid jet nozzle is used for being connected to form jet and negative pressure along conduit axis with high pressure liquid source.
Further, the described dirt pipe two ends of going out comprise the male and female connector, and the rear male and female connector of the described dirt pipe jet direction of going out is connected with the pipeline of carrying dust, and the place ahead is connected in the pipeline of collecting refuse.
Further, described fluidic module comprises first fluid jet nozzle at least, can comprise second fluid jet nozzle, described first fluid jet nozzle comprises input port and at least one nozzle, described second fluid jet nozzle comprises input port, delivery outlet and at least one nozzle, the input port of described first fluid jet nozzle composition fluidic module that can be connected with the delivery outlet of second fluid jet nozzle.
For easy to connect, connect by the shower nozzle connector between described first fluid jet nozzle and second fluid jet nozzle, described shower nozzle connector comprises the interface that can be respectively be connected with the delivery outlet of the input port of first fluid jet nozzle and second fluid jet nozzle.
Concrete, the delivery outlet of the input port of described first fluid jet nozzle and second fluid jet nozzle is female thread structure, the interface of shower nozzle connector is the external thread structure that matches.
Preferably, described high pressure liquid source is provided by booster pump, and described liquid is water.
The invention has the beneficial effects as follows: the present invention is used for the tunnel, colliery and changes the hole dirt that goes out and belong in the industry novelty and use by settle the high-pressure spray shower nozzle to form fluidic system at the dirt pipe interior orientation that goes out, have following having a few, at first can make dust deposit form fluid mixture by the fog-like liquid (water) that shower nozzle sprays so that handle, simultaneously because the jet effect that the shower nozzle spraying produces has formed jet flow negative pressure in the dirt pipe that goes out, this negative pressure can suck the dirt pipe that goes out endlessly with the dust that ejects in the boring and handle, and the dirt effect of going out is promoted greatly.
