The utility model content
The technical problem that the utility model solves: a kind of multifunction storage coal yard spontaneous combustion treating apparatus is provided, utilize compressed air to discharge potential energy suddenly, produce the intense impact ripple, make the swollen arch in coal seam, depths and bulk, so that conduit advances to the depths, coal seam, utilize the swollen arch in coal seam and bulk in cave in and compression ignite is carried out in the impact of blast.When compression ignite is not thorough, can implement water logging or add extinguishing chemical (dry powder class) integrated treatment is carried out in spontaneous combustion by conduit again.Also can add the chemoprophylaxis spontaneous combustion by conduit.
The technical solution adopted in the utility model: a kind of multifunction storage coal yard spontaneous combustion treating apparatus comprises air bubble, frame, hoist engine and air compressor.Described frame, hoist engine and air compressor all are arranged on the supporting plate, and vertical fixing has slide rail on the frame, and air bubble is installed on the slide rail, and the lower end of slide rail is provided with elastic buffering mechanism; The intake valve of air bubble upper end is connected with air compressor by high-pressure hose, the exhaust outlet of air bubble lower end is connected with conduit by flange, and the pointed through hole that passes supporting plate central authorities of the awl of conduit lower end, the central authorities of supporting plate are provided with the lead ring that can lock conduit, and lead ring be positioned at through hole directly over; The upper end of frame is equipped with leading block, and an end of steel wire rope is fixed on the upper end of air bubble, and the other end is walked around leading block and is connected with hoist engine.
Described conduit is formed by connecting by more piece, connects by pipe collar between adjacent two conduits, and pointed and both sides are shaped on bar hole for awl bottom for it.
Described intake valve is connected with high-pressure hose by ready-packaged joint.
Advantage that the utlity model has and effect:
1, the utility model is used for the coal yard spontaneous combustion with air bubble and handles, and makes the swollen arch in coal seam, depths and bulk, utilize the swollen arch in coal seam and bulk in cave in and compression ignite is carried out in the impact of blast.When compression ignite is not thorough, also can implement water logging or add extinguishing chemical (dry powder class) integrated treatment is carried out in spontaneous combustion by conduit.
2, utilize the utility model to carry out coal yard spontaneous combustion processing and can reduce the former coal losses that causes owing to spontaneous combustion effectively, the protection environment.Utilize the utility model to add chemicals and also can effectively prevent spontaneous combustion.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing 1 a kind of embodiment of the present utility model is described.
A kind of multifunction storage coal yard spontaneous combustion treating apparatus comprises air bubble 1, frame 2, hoist engine 3 and air compressor 6.Frame 2, hoist engine 3 and air compressor 6 all are arranged on the supporting plate 13, and vertical fixing has slide rail 7 on the frame 2, and air bubble 1 is installed on the slide rail 7, and the lower end of slide rail 7 is provided with elastic buffering mechanism 8; The intake valve 14 of air bubble 1 upper end connects by ready-packaged joint 10 high-pressure hoses 11; High-pressure hose 11 is connected with air compressor 6, the exhaust outlet of air bubble 1 lower end is connected with conduit 5 by flange 15, and the pointed through hole 18 that passes supporting plate 13 central authorities of the awl of conduit 5 lower ends, the central authorities of supporting plate 13 are provided with the lead ring 9 that can lock conduit 5, and lead ring 9 be positioned at through hole 18 directly over; The upper end of frame 2 is equipped with leading block 16, and an end of steel wire rope 12 is fixed on the upper end of air bubble 1, and the other end is walked around leading block 16 and is connected with hoist engine 3.
Operation principle: using time frame 2 can be fixed on the coal pusher, then the utility model is moved to the top of self-ignition of coal pile point, air bubble 1 is promoted to the top of frame 2 by hoist engine 3, and compressed air is stored in the steel air bubble 1, when big gun body internal gas pressure reaches 0.4-0.8MPA, electronic by electric cabinet 4 controls, pneumatic element, cut off compressed air stream, cut off the electromagnetism air-flow, open the exhaust outlet of electromagnetic block pendulum valve, move the exhaust outlet of opening air bubble 1 with great pressure after pressure differential forces piston before and after the piston moment formation, compressed air is sprayed with high speed to predetermined direction in a flash, utilize compressed air to discharge potential energy suddenly, the intense impact ripple of generation sprays from bar hole, make the swollen arch in coal seam, depths and bulk, so that conduit 5 advances to the depths, coal seam.Conduit 5 is finished after for the first time the degree of depth advances, and promotes air bubble 1 once more, connects standby conduit 5, advances aforesaid operations up to self-ignition point repeatedly, utilize in the swollen arch in coal seam and in bulk cave in and compression ignite is carried out in the impact of blast; When compression ignite is not thorough (rising to the mouth of pipe by flue gas along conduit 5 just knows), implement water loggings or add extinguishing chemical (dry powder class) by conduit 5 again integrated treatment is carried out in spontaneous combustion.After handling successfully to spontaneous combustion, make conduit 5 go deep into 1.0-1.5 rice downwards again, add ammonium nitrate (chemical fertilizer matter) 0.5 kilogram in the conductive pipe 5 then, add ammonium nitrate and once release again after 10 minutes and can operate, so that ammonium nitrate is spread.The purpose that adds ammonium nitrate is that the volatile component (as CH4, H2, CO2 etc.) that decomposing oxidation in the coal is overflowed is transformed.Ammonium nitrate and hydrogen effect generate nitrogen and water under general case, reduce because quick-fried depths, the coal seam spontaneous combustion possibility that causes of small-sized hydrogen reaches prevention spontaneous combustion purpose with this.
