Description

Flitting long tube type high pressure water fog dust cleaning method and device
The present invention relates to flitting long tube type high pressure water fog dust cleaning and device, be particularly useful for coal mine fully-mechanized mining face, comprehensive coal face, general twin-roll and the single ended shearer of adopting face.
Longwall machinery coal-face drum shearer depositing dust problem is one of technical barrier that coal industry faces in the world wide under the coal mine.Under the situation of not taking any measurements for reduction, one ton of coal of the every evil of coal-winning machine will produce 2 * 10 usually 5～5 * 10 5The mg coal dust.External spraying, coal seam shift to an earlier date measurements for reduction such as water filling in the cylinder that adopts at present, and the dust-producing amount that coal-winning machine whenever cuts one ton of coal can be reduced to 10 4～1.2 * 10 4Mg, but around the coal-winning machine and rear (following distinguished and admirable), the dustiness in every cubic metres of air is still up to more than 200～1000mg.Work under coal miner's sd so condition, not only reduced workman's production efficiency, increased the probability that various industrial accidents take place, but also hiding the possibility that coal-dust explosion takes place in the hiding, threaten mine safety production.
Problem in view of the prior art existence, the purpose of this invention is to provide an a kind of end sprays the long tube type high pressure water fog dust cleaning method of water smoke and realizes that this method is arranged on the long tube type high pressure water fog dust cleaning device on the flitting to the other end, it moves work simultaneously with coal-winning machine, can improve the working environment under the coal mine effectively.
Flitting long tube type high pressure water fog dust cleaning method of the present invention enters growing tube in coal-winning machine machine side on water under high pressure by high-pressure rubber pipe with high-pressure hydraulic pump, and high-pressure rubber pipe is packed into and dragged in the cable clamp, is dragged by coal-winning machine with cable; Water under high pressure enters long through high-pressure rubber pipe, and the nozzle group that is provided with in long tube sprays water smoke by an end of long to the other end.Two groups of nozzles that are provided with in the long tube are alternately opened, are stopped, and the direction that main jet is chewed spraying is always opposite with the shearer haulage direction, and is consistent with the air draught direction; Auxiliary nozzle spray direction is consistent with lead, and is opposite with the air draught direction.The pressure of the water under high pressure of being got by high-pressure pump is controlled to be 15～20MPa, and flow is 0.5～1% of a coal-winning machine coal cutting amount.
Flitting long tube type high pressure water fog dust cleaning device of the present invention, one long steel plate tube longitudinally is set on the machine side of coal-winning machine, its length is greater than coal-winning machine body length, less than the distance of shaft centers of two ends coal cutting cylinder, the two-port of long tube is the bell mouth shape of oblique cylinder, is provided with two groups of main jet spray paintings in the long tube and chews, the angle inboard at two ends, one group of auxiliary nozzle respectively is housed, and each is organized nozzle and connects high-pressure rubber pipe, and the high-pressure hydraulic pump that is provided with in high-pressure rubber pipe and the gallery is linked together.For easy accessibility, it is a gastight integral body that long tube is connected by some joints, and in coal mining machine side top, the section of long tube can be square, also can be circular with bolton.The high-pressure rubber pipe of connection nozzle group and high-pressure hydraulic pump is packed into and is dragged in the cable clamp.
Flitting long tube type high pressure water fog dust cleaning method of the present invention and device, at the flitting machine side one long steel plate tube is set vertically, in the long tube main jet is set and chews and assist the nozzle group, water under high pressure is introduced in the long tube that is provided with on the coal-winning machine machine side, under the nozzle group ejection water smoke effect that in long tube, is provided with, make an end of long letter produce negative pressure, play the dust suction effect.On the basis of original inside and outside atomizing de-dusting, the dust concentration in the coal-winning machine ambient air is reduced by 80～90%, promptly dust content can be reduced to 20～100mg/m in the work plane air 3Below, wherein respirable dust concentration can be reduced to 10～30mg/m 3Below, improved the working environment of coal-face greatly, guarantee that the workman is healthy, raise labour productivity, can stop the generation of coal-dust explosion fully.Its good reliability, simple in structure, cost is low, and is easy to operate, safeguards simply to have practicality widely.
