Abstract
The invention belongs to the field of coal mine dust control and in particular relates to a process for controlling dust in a belt roadway by sections through water spray. The invention aims to solve the technical problem of control of coal dust in tape haulage roadways or intake and return air roadways. The process is characterized in that a spraying device is arranged every 40-60 meters in the roadway; water atomization spray nozzles are arranged on the spraying devices; the distance between the water atomization spray nozzles is 0.3-0.5 meter; the water filtration precision reaches 1000 meshes; and the water pressure is 1-10MPa. The process has the following beneficial effects: the aims of effectively controlling the dust concentration under the shaft and improving the labor hygiene conditions of the working surfaces are achieved; the dust in the roadway is reduced below the harm level; the safety of mine production is improved; and the health of miners and the working environment are protected.
Description
Technical field
The invention belongs to Mine Dust and administer the field, be specifically related to a kind of thin water spray segmentation control belt lane dust technology.
Background technology
Coal dust concentration under the coal mine in adhesive tape haulage drift or the well return airway generally exceeds standard seriously, and distinguished and admirable speed 2-3 rice/s generally directly utilizes down-hole static pressure water spray depositing dust; But because atomization mechanism uses and lays unreasonablely, the atomised spray of formation is of poor quality, the water curtain that many times forms; The water droplet particle is big, and skewness drenches object easily and forms ponding; Make a part of dust can't be infected with water, the dust-laying effect that can't obtain.The dust that suspends not only pollutes working environment, also easily workman's health worked the mischief, and the hidden danger that still causes the accident easily, therefore being badly in need of a kind of effective depositing dust means eliminates this harm.
Summary of the invention
The present invention provides a kind of thin water spray segmentation control belt lane dust technology in order to solve the technical problem of the improvement of coal dust in adhesive tape haulage drift or the air entering and returning tunnel.
The present invention is realized by following technical scheme; A kind of thin water spray segmentation control belt lane dust technology; Every separated 40-60 rice is arranged atomization mechanism one in the tunnel, is connected with thin water atomization shower nozzle on the described atomization mechanism, and distance is a 0.3-0.5 rice between the thin water atomization shower nozzle; The water filtration precision reaches 1000 orders, water pressure 1MPa～10MPa
.
Thin water spray segmentation control belt of the present invention lane dust technology is that a kind of down-hole static pressure water that utilizes is also through behind the strict filtration, purification; Spray micron-sized water smoke through thin water atomization shower nozzle again; Water forms in the tunnel and effectively catches dust water smoke, and water smoke is even, and suspension time is long; Droplet density is high and the dust joint efficiency is high.Thin water spraying device adopts pure frame for movement, need not power supply, and is simple in structure, easy for installation, safe in utilization.
Thin water spray segmentation control belt of the present invention lane dust technology is mainly used in the depositing dust in the adhesive tape haulage drift under the coal mine, has realized the dust concentration under effective control well, improves the purpose of the labour health condition of work plane.It is below horizontal to make dust in the tunnel be reduced to harm, the safety of producing of raising mine, protection and the miner is healthy and working environment.
Description of drawings
Fig. 1 is the roadway arrangement structural representation
Fig. 2 is the syndeton sketch map of atomization mechanism
Among the figure: 1-water purifier, 2-ball valve, the straight-through spray seat of 3-, 4-jet pipe, the straight-through spray seat of 5-, 6-terminal spray seat, 7, the thin water atomization shower nozzle of 8-, 9-water inlet pipe, 10-tunnel, 11-atomization mechanism.
The specific embodiment
Meaning as shown in Figure 1, a kind of thin water spray segmentation control belt lane dust technology, every separated 40-60 rice is arranged atomization mechanism 11 one in tunnel 10; Meaning as shown in Figure 2, described atomization mechanism 11 comprises water inlet pipe 9, water purifier 1; The thin water atomization shower nozzle 8,7 of series connection; Distance is a 0.3-0.5 rice between the thin water atomization shower nozzle, and the water filtration precision reaches 1000 orders, water pressure 1MPa～10MPa
.
The atomization mechanism concrete structure is that the water inlet pipe 9 that connects successively connects on water purifier 1, ball valve 2, jet pipe 4, the jet pipe 4 and leads directly to spray seat 3,5, terminal spray seat 6 and be installed in the thin water atomization shower nozzle 8,7 that sprays on the seat.Open the ball valve of logical supply channel, let foreign material in the whole pipeline pour off after, close the ball valve of supply channel again, be screwed in thin water atomization shower nozzle on straight-through spray seat and the terminal spray seat again, open the ball valve of logical supply channel again and start working.
The atomizing effect of thin water atomization shower nozzle reaches micron order, and water yield is little, can open for a long time, and personnel are passing can not drenched, and ground, tunnel is ponding not, can effectively catch aerial floating dust, and the efficiency of dust collection in the whole piece tunnel is reached more than 90%.
Thin water atomizing nozzle (head) is conventional products on the market-Guangzhou victory industrial spray nozzle equipment difficult to understand Co., Ltd; Adopt copper material; The specification of using: 3 ﹟-8 ﹟; Only adopt fluid pressure just can produce very tiny drop, the average particulate diameter of drop has only about 50 microns, and minimum atomizing particle size can reach 20 microns.Water purifier adopts stainless steel, filtering accuracy 1000 orders, and hydraulic pressure accommodation: 0.2 MPa～10.0MPa, the hazardous area that can be used for that gas is arranged, coal dust etc. explodes,
2 meters/s of adhesive tape transportation lane wind speed wind speed; Condition under control spraying coverage be 50m; Then according to per 50 one group of atomization mechanism is installed and is provided with, water atomization best results under corresponding pressure guarantees all to tackle dust at this section; Make water supply volume 3-5L/min, ground does not produce ponding.
