Description
Technical field
The invention belongs to dust removing down-hole field, and in particular to a kind of be used to suppress the fine atomization foam of underground coal mine dust
Dust arrester.
Background technology
With the increase of coal mine machinery degree, colliery is such as mined, tunneled in process of production, transport and lifting are each
Link, can produce substantial amounts of dust, not only pollute the environment of each setting in underground, also to the health band of operating worker
Come seriously endanger, underground labour's operation in high concentrate dust environment for a long time, respirable dust can be sucked, will suffer from coal pneumoconiosis,
The diseases such as silicosis, at present, pneumoconiosis have become the No.1 occupational disease in China, the coal industry direct economy caused by pneumoconiosis every year
Billions of members are lost, therefore, strength should be increased and carry out the detection of Mine Dust, preventing and controlling, to prevent similar incidents again
Occur.
Mine dust control technology is the synthesis dust prevention skill after a complicated system engineering, particularly high gas layer extraction
Art, high methane easily most of projecting coal bed middle mine dust belong to hydrophobic property, and water is difficult that prolonged extraction is moistened and passed through to it,
Large quantity of moisture is lost in coal seam, causes coal seam to dry dust-producing amount increase.From the perspective of energy, wetting agent is added in water
Reduce the surface tension of liquid, be not only advantageous to improve the water imbibition of coal dust, and should be able to make wetting agent change rapidly it is solid-
The property at liquid interface, increase substantially the moistening degree to dust granules.
The conventional technology of present atomizing de-dusting has：The automatic light-operated spray technique of coal-face unit walking, coal-winning machine are high
Press external spraying dust-settling technology, negative pressure secondary depositing dust, spray suction auxiliary with reference to dust-settling technology, coal-winning machine radial direction mist screen and hydraulic support spy beam
Atomizing de-dusting technology, hydraulic moving stand auto spraying dust-settling technology, foam dust-removing technology are helped, in addition, in order to prevent and treat tunnel fortune
The diffusion of the place such as defeated, transfer point dust, automatic sprayer are also widely used.
Wherein, foam dust-removing technology mainly uses net formula foam maker, and its operation principle is that foam solution is sprayed to hair by shower nozzle
On indulging in serfing the Net, liquid film is formed, compressed air advertises liquid film foaming, causes to can not form on foam screen if the pressure of foam solution crosses conference
Liquid film, if compressed air pressure is excessive, the liquid-sheet atomization on foam screen can be caused, it is impossible to produce foam, and underground coal mine
The pressure of water and compressed air is all very big, is unfavorable for net formula foam maker in down-hole application.
The content of the invention
The purpose of the present invention is to be directed to the deficiencies in the prior art, there is provided a kind of one migration easy to connect, random,
The fine atomization foam dust-removing device for being used to suppress underground coal mine dust that dustfall efficiency is high, using effect is good, is created for labourer
Good working environment, reduce the incidence of pneumoconiosis.

The screw thread of base connection, shower head pipe are internally provided with mist pipe, and the mist pipe is followed successively by reaming sections of atomization, mesopore from the front to the back
Boost section, shrinkage cavity pressure regulation section, foams mix section, the reaming sections of atomization are the infundibulate pipe of one big mouth forward, shrinkage cavity pressure regulation
The Duan Weiyi big infundibulate pipe of mouth backward, reaming sections of atomization are connected with shrinkage cavity pressure regulation section by mesopore boost section, mesopore supercharging
Duan Weiyi tubule, both ends are in the same size, and shrinkage cavity pressure regulation section big opening end is connected with foams mix section, and the injection cover is a cone
Shape cover, cone-shaped hood cone are provided with some spray holes on bottom side, some secondary-atomizing injections are circumferentially provided with cone-shaped hood side wall
Hole.
The section of described mesopore boost section is circular or ellipse.
The mesopore boost section section is circular, a diameter of 1.2mm.
The length of the mesopore boost section is 2.5-3.5 times of diameter of section.
Beneficial effects of the present invention：The fine atomization foam dust-removing device of the present invention, is greatly improved coal mine machinery digging work
Make the dust suppression efficiency in face, efficiently solve that working face dust is high to have a strong impact on safety in production and worker is physically and mentally healthy asks
Topic, it may be either that getting working face creates good working environment, improve the operating efficiency of underground operators, while can drop significantly
The low line worker of getting working face one suffers from the probability of occupational disease.
