Abstract
The invention discloses a device for filling surface subsidence with smoke and quick lime, and belongs to the technical field of surface subsidence security governance. The device comprises a gas inlet unit and a slurry inlet unit. The gas inlet unit comprises a smoke pipe and a draught fan. The smoke pipe can extend into a hole to be filled. The slurry inlet unit comprises a slurry pipe and a container for bearing quick lime slurry. The slurry pipe can extend into the hole to be filled. An exhaust pipe communicated with surface external environment is further arranged on the hole to be filled. When the smoke injected into the hole makes contact with the quick lime slurry, because the smoke and the quick lime slurry both have mobility, the hole can be filled; the smoke and the quick lime slurry can have a chemical reaction, and therefore the hole under the ground surface can be filled. The device is ingenious in design, convenient to use, capable of saving energy, environmentally friendly and capable of effectively solving the problem that by means of an existing sandy soil and coal gangue filling method, sandy soil and coal gangue can not go deep into a gap in the ground surface.
Description
Technical field
The invention belongs to the safe Treatment process field of surface subsidence, relate to a kind of device utilizing flue gas and quicklime to fill up earth's surface to cave in.
Background technology
In recent years, large scale mining is carried out in many collieries of Yulin, Shanxi and Inner Mongol, causes serious destruction to surrounding environment, and mining subsidence causes that main soil, mining area caves in, road caves in, Building Deformation etc.Existing solution subsidence or the effective ways caved in are underground filling method and overlying strata separation layer carrying space filling method, and coal ore and the sandy soil of adopting, as packing material, need with loader landfill and compacting more meanwhile.Like this needs are used loader collection, carry more sandy soil, larger input can be caused.And such burying method only can administer the region that collapsing appears in surface, the cavity for inside then cannot process.If things go on like this, will potential safety hazard be formed, be unfavorable for the safety in production life in mining area.
Summary of the invention
The object of the present invention is to provide a kind of device utilizing flue gas and quicklime to fill up earth's surface to cave in, this apparatus structure is reasonable in design, simple, effectively can solve sandy soil and gangue landfill method in prior art and cannot go deep into the problem of earth's surface internal voids.
The present invention is achieved through the following technical solutions:
The invention discloses a kind of device utilizing flue gas and quicklime to fill up earth's surface to cave in, comprise air admission unit and enter to starch unit; Described air admission unit, comprises fume pipe and blower fan, and fume pipe can stretch in hole to be filled up; Describedly enter to starch unit, comprise mud tube and the container for taking up quicklime slurry, mud tube can stretch in hole to be filled up; The direction that fume pipe and mud tube stretch into hole to be filled up is different; Hole to be filled up also arranges the stack be connected with earth's surface external environment, stack is also provided with bleed off pipe.
The pipeline of fume pipe is provided with the first stop valve, temperature takes into account first flow meter.
The pipeline of mud tube is provided with pump and the second stop valve.
Stack is provided with second gauge.
Also agitator is provided with in container.
Fume pipe exports with chimney of electric plant or kiln exports and is connected.
Compared with prior art, the present invention has following useful technique effect:
The device utilizing flue gas and quicklime to fill up earth's surface to cave in disclosed by the invention, comprise air admission unit and enter to starch unit, air admission unit comprises fume pipe and blower fan, and flue gas is pumped in the hole under earth's surface by blower fan.Enter to starch the container that unit comprises mud tube and takes up quicklime slurry, quicklime slurry is also sent in the hole under earth's surface by mud tube, when passing into the flue gas in hole and contacting with quicklime slurry, because the two all has mobility, can load hole, and the two chemical reaction can also occur, thus complete the landfill to hole under earth's surface.This apparatus design is ingenious, easy to use, energy-conserving and environment-protective, effectively can solve the problem that existing sandy soil and gangue landfill method cannot go deep into earth's surface internal voids.
Further, fume pipe and stack are provided with flow meter respectively, quicklime slurry can be monitored and carry out state with the reaction of flue gas, when two flow meters difference in flow close to zero time, show that reaction terminates.
Further, in the container taking up quicklime slurry, also agitator is set, quicklime slurry can be stirred.
Further, fume pipe can export with from chimney of electric plant or kiln exports and is connected, and can make full use of the energy, energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1 is blower fan; 2 is fume pipe; 3 is the first stop valve; 4 is thermometer; 5 is first-class gauge; 6 is earth's surface; 7 is stack; 8 is hole; 9 is soil horizon; 10 is mud tube; 11 is the second stop valve; 12 is pump; 13 is agitator; 14 is container; 15 make a living lime mortar; 16 is bleed off pipe; 17 is second gauge.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
See Fig. 1, there is soil horizon 9 and hole 8 in the below on earth's surface 6.The device utilizing flue gas and quicklime to fill up earth's surface to cave in disclosed by the invention, comprises air admission unit and enters to starch unit; Described air admission unit, comprises by fume pipe 2 and blower fan 1, and fume pipe 2 can stretch in hole 8 to be filled up; Describedly enter to starch unit, comprise mud tube 10 and the container 14 for taking up quicklime slurry, mud tube 10 can stretch in hole 8 to be filled up; Hole 8 to be filled up also arranges the stack 7 be connected with earth's surface external environment.
The pipeline of fume pipe 2 is provided with the first stop valve 3, thermometer 4 and first-class gauge 5.The pipeline of mud tube 10 is provided with pump 12 and the second stop valve 11.Stack 7 is provided with bleed off pipe 16 and second gauge 17.
Preferably, in container 14, agitator 13 is also provided with.The direction that fume pipe 2 and mud tube 10 stretch into hole 8 to be filled up is different, and fume pipe 2 exports with chimney of electric plant or kiln exports and is connected.
The device utilizing flue gas and quicklime to fill up earth's surface to cave in of the present invention, in use:
First open the second stop valve 11, close the first stop valve I3, open agitator 13, stirred by the quicklime slurry in container 14, then these quicklime slurry mud tubes 10 are sent in the hole 8 below earth's surface 6 by pump 12, when mud overflows from bleed off pipe 16, close pump 12 and the second stop valve 11, open blower fan 1 and the first stop valve 3, flue gas is pumped in hole 8, when the difference in flow of first-class gauge 5 and second gauge 17 is almost 0, show that reaction terminates.
