Technical Field

[0001] The multi - component composite dust removal device for main underground roadways in mines of the present invention belongs to the field of dust control in main underground roadways of mines. Specifically, it relates to a device that generates changes in surface tension and interfacial polarity effects through the relative movement of the air - dynamic force and the water particle group interface, enabling the continuously changing and moving water particle group to occupy this limited space of the main roadway, so that the dust in the main roadway cannot produce a drilling - through effect, and realizing the multi - component composite treatment of roadway dust by the gas - atomized dynamic fluid. The device has a simple structure, is easy to operate, and has reliable performance. The key is that it can effectively overcome the drilling - through effect of the aerosol formed by the combination of dust and gas by the dynamic fluid, thereby enabling the treatment of flexible and dynamic dust. Background Art

[0002] With the popularization of coal - mining mechanization underground, while the tunneling and coal - winning efficiency have been improved, the dust hazard generated has also increased day by day. To reduce dust dispersion, nozzles are set on fully - mechanized mining equipment and the cutters of full - face roadheaders. However, the nozzle dust removal technology on the cutters of current full - face roadheaders has the problem of uneven water mist formation by high - pressure nozzles, which easily affects the dust removal effect and also causes the environmental problem of water accumulation in the tunneling roadway. The dust enters the main roadway along with the air current, resulting in a large amount of suspended dust often generated in the underground working roadway of the mine. The dust and air are easily condensed and combined to form an aerosol. The aerosol obtains sufficient kinetic energy along with the air current, so it is very difficult to be treated. When workers walk or work in it, their vision is blurred, the visibility is low, and safety accidents are likely to occur. In addition, if workers inhale dust for a long time, they are prone to pneumoconiosis, which causes great harm to the physical and mental health of employees. Application No. CN202311342715.0, a dust - removing and poison - filtering device for underground roadways in metal mines and its use method; the main body mechanism of the invention, one side of the outer wall of the main body mechanism is fixedly connected with a housing mechanism, the outer surface of the housing mechanism is fixedly connected with a water source delivery mechanism, and the outer surface of the housing mechanism is fixedly connected with a purification mechanism. Through the combined action of the main body mechanism, the housing mechanism, the water source delivery mechanism and the purification mechanism, the dust generated during the mining process is effectively adsorbed and then transported and processed. During the mining process, a water wall is used to isolate the mining environment from the roadway to prevent the spread of dust. And then a purification mechanism is arranged behind the water wall, which can filter and adsorb the harmful dust substances that penetrate through the water wall. Obviously, the water - wall dust removal technology and the adsorption and filtration technology cannot effectively solve the drilling - through effect of aerosol dust, and this patented technology is ineffective for roadway dust control. Application No.: CN202322674362.6, a dust removal device for coal mine safety production roadways, comprising: a housing, on the surface of which a ventilation chamber is provided, inside which a fan is arranged; inside the housing, a water storage chamber is provided, which is filled with dust-removing water; on the inner bottom wall of the ventilation chamber, an installation groove communicating with the water storage chamber is provided; by providing a fan, a dust collection structure and an auxiliary structure, under the action of the fan, dust and air inside the roadway can be introduced into the ventilation chamber, under the action of the filter plate, dust can be intercepted, and under the action of the auxiliary structure, the dust-removing water can be introduced into the connecting pipe, so as to spray dust through the nozzle, but this technology cannot solve the aerosol dust pollution in the main roadway; Application No.: CN202321813702.2, a dust removal device for a roadway supplied by a forced local ventilator, comprising a wind tunnel, a turbine, a controller and a water atomization mechanism; the turbine is arranged inside the wind tunnel. When there is air flow inside the wind tunnel, the turbine is driven to rotate. The rotating turbine converts the air flow inside the wind tunnel from a turbulent state into a columnar eddy current. The controller is used to control the operation of the water atomization mechanism. The water atomization mechanism comprises a plurality of water mist nozzles and a water delivery pipe. A plurality of the water mist nozzles are arranged on the inner wall of the wind tunnel, and the water delivery pipe is connected to an external water supply system; the utility model realizes the refinement of water mist and the more uniform dispersion of water mist under the action of high-speed air flow, so that the water mist can evenly contact the rock surface to be excavated, thus achieving a better dust removal effect. At the same time, the refinement of water mist can avoid the problem of water accumulation and solve the problem of atomization of the dust removal fluid. However, the proportion of the dust removal fluid relative to the air in the wind tunnel is too low to overcome the drilling effect of aerosol dust; CN219826908U, a dust removal spray system for mine roadways, comprising a roadway body, on the bottom surface of which a slide rail is fixedly connected, and on the top surface of which a spray vehicle assembly is arranged. The spray vehicle assembly comprises an automatic mine car, a rotating pipe and a gear. The automatic mine car is located on the top surface of the slide rail. Two rotating pipes are rotatably connected to the top surface of the automatic mine car. Two water pipe hoses are movably connected to the circumferences of the bottoms of the two rotating pipes. The two water pipe hoses are movably connected to two telescopic water pipe reels. Two spray water pipes are fixedly connected to the top surface of the inner wall of the roadway body. Through the cooperation of the spray water pipes, the second nozzles and the spray vehicle assembly, the roadway body can be well covered to ensure that there are no dead corners in dust treatment. By means of the walking wheel mechanism, the fluid operation space is increased, but it is still ineffective against the drilling effect of aerosol dust, and the pollution problem is still prominent; Therefore, there is an urgent need for a simple, reliable and easy-to-implement device for dust treatment in the main roadways of underground mines in the field of on-site work.

Under the dynamic aerosolization action of the water particle group fluid, the dust in the form of aerosol in the roadway undergoes a coagulation effect with the liquid droplets, effectively solving the problem of the difficult-to-control aerosol generated by dust and air. The dust in the form of aerosol in the roadway coagulates with the granulated fluid into large particle liquid-solid states, and the harmless large liquid-solid particles are transported out together with the solid substances on conveying equipment such as belt conveyors to ensure the normal progress of production.
