Abstract
The present invention discloses a mine dedusting method. The mine tunnel is equipped with atomization device which can generate water fog, the mine tunnel and mining area are equipped with a plurality of spraying points, the installation quantity of spraying points is changes in accordance with the humiture in mine along the depth: the quantity of spraying points is increased along the rise of temperature and the drop of dampness; the water fog ejected from spraying points adsorb the coal dust in air and moisten the tunnel wall along the ventilating current in mine tunnel and mining area, the wet dusts collide each other and the affinity is bigger, finally the dust falls down in the tunnel and mining area, so the dedusting action is completed. The invention considers the influence from mine environment ventilation and humiture change to mine dust fully, the water use is less, the performance is reliable, the fog action has wide scope, the method can block and eliminate dust in tunnel effectively and has no impact to the coal quality basically.
Description
Technical field
The present invention relates to a kind of atomising device that is used for the mine dedusting.
Background technology
The mine control is one of important subject of safety of coal mines always, and is well-known, and wet dust removal is the most general a kind of method of using under the mine, the moistening dust of water energy increase grit gravity, and the grit that will carefully loose is polymerized to bigger grit, make floating dust quicken sedimentation, dust fall is difficult for flying upward.
But traditional wet dust removal method is that press water is sprayed on airborne dust point with the form of jet by shower nozzle, the method does not consider that Minepit environment ventilates, humiture changes the influence to mine dust, atomizing effect is relatively poor, sphere of action is little, shower nozzle easily stops up, because of water supply volume is big, influence the quality of coal.
Summary of the invention
Technical problem to be solved by this invention is to avoid above-mentioned deficiency of the prior art, and proposes a kind of mine dedusting atomising device that mine integral body is atomized.
Technical scheme provided by the present invention is: a kind of atomising device that is used for the mine dedusting, include a pumping plant, one air compressor machine and some spraying assemblies, pumping plant links to each other by pipeline with the spraying assembly with air compressor machine, it is characterized in that: this spraying assembly includes main body, shower nozzle and end cap; Described main body is an annular, and is provided with the two through hole that links to each other with the pumping plant pipeline on its opposite flank; Described shower nozzle comprises chassis and nozzle, and this chassis and circumferential body are tightly connected, and this nozzle and chassis are connected as a single entity, and identical with the main body axial height, and is axially arranged with the air vent that is connected with the air compressor machine pipeline along main body, and radially is provided with an aperture along main body; Described end cap is fixedlyed connected with main body, and axially is provided with the hole along the nozzle air vent.Described air vent is made as two ends diameter horn-like greater than mid-diameter.Described aperture is located near the outlet side of nozzle.
The present invention has following advantage: take into full account that Minepit environment ventilates, humiture changes the influence to mine dust, atomizing effect is good, and water is few, dependable performance, and mist body sphere of action is extensive, can ature of coal not had influence substantially effectively at tunnel internal resistance dirt, the dirt that goes out.
Description of drawings
Fig. 1 is the structure cross-sectional schematic of spraying assembly of the present invention.
Wherein: 1: main body 2: shower nozzle 21: chassis 22: nozzle 3: end cap 4: air vent 5: aperture
The specific embodiment
As everyone knows, underground mining must ventilate, and the Northwest winter daily mean temperature abundant in China's output of coal is very general at-10 ℃～-5 ℃, and the underground work temperature is about 20 ℃; And airborne water content varies with temperature and changes, and air is in the process of circulation of tunnel, and along with temperature raises, the ability that absorbs moisture also improves constantly, and therefore, will make tunnel and minery become dry unusually, thus easier generation dust.
A kind of mine dust collection method is that the atomising device that produces water smoke is set in mine laneway, some spraying points are set in mine laneway and in the minery, the quantity that is provided with of spraying point changes along with change in depth according to humiture in the mine, reducing the spraying number of spots with temperature rising and humidity increases, the water smoke of spraying point ejection is along with coal dust in the distinguished and admirable absorbed air in the mine laneway and in the minery and moistening wall, wet dust is collided affine each other and is become big, finally drop in the tunnel and in the minery and play the dedusting effect, easily produce airborne dust point place or mine humiture catastrophe point at dust, being provided with is enough to the spraying point that prevents that dust from kicking up.
According to above-mentioned dust collection method, cooperating with the rich and powerful plant equipment in Longkou Co., Ltd in Wan Li branch company of China Shenhua Energy Co., Ltd one ore deposit, implements this method in March, 2006 in ten thousand sharp ore deposits.Use through two weeks obtains tangible dust removing effects.(seeing the following form)
Adopt above-mentioned dust collection method, improved airborne relative humidity, be implemented in the dust in the absorbed air in the ventilation, and further catch dust, thereby avoided coal dust to participate in the possibility of blast.
Used a kind of atomising device when implementing above-mentioned dust collection method, it includes a pumping plant, an air compressor machine and some spraying assemblies, and pumping plant links to each other by pipeline with the spraying assembly with air compressor machine.As shown in Figure 1, this spraying assembly includes main body 1, shower nozzle 2 and end cap 3; Main body 1 is an annular, and is provided with the two through hole that links to each other with the pumping plant pipeline on its opposite flank; Shower nozzle comprises chassis 21 and nozzle 22, this chassis 21 is tightly connected with main body 1, this nozzle and chassis 21 are connected as a single entity, and it is identical with main body 1 axial height, and be axially arranged with the air vent 4 that is connected with the air compressor machine pipeline along main body 1, air vent 4 is made as two ends diameter horn-like greater than mid-diameter, and radially is provided with an aperture 5 along main body, and aperture 5 is located near the outlet side of nozzle 22; End cap 3 is fixedlyed connected with main body 1, and axially is provided with venthole along nozzle air vent 4.
The spraying assembly be arranged in the tunnel and the minery in, pumping plant provides water, air compressor machine produces pressure-air, both are connected with the assembly of spraying by pipeline; Water rotates in the cavity of spraying assembly, and the negative pressure that the pressure-air that is ejected produces is taken out of, to the mixture of tunnel or minery ejection mist and little water droplet, the dust in the absorbed air.For the airborne dust point of easy generation dust, can settle some spraying assemblies more.
This atomising device spray amount is big, and suitable large space is caught dirt at a distance, negative pressure-induced spraying, and atomizing effect is good, water saving; The mist field is even between whole plenum area, and water quality is not had specific (special) requirements; And spraying assembly volume I is removed at any time, and segmentation connects soon.
