Abstract
The invention discloses a coal mine underground movable multi-component foam fire extinguishing system, which is used for preventing and controlling spontaneous combustion of coal at a goaf in a coal mine. The coal mine underground movable multi-component foam fire extinguishing system comprises a stirring device (2), a proportioning mixer (3), a mixer (4), a booster pump (5), a foam maker (6), a foam distributor (7) and a foaming agent tank (8), wherein the front end of the foam maker is provided with an air inlet passage; and the air inlet passage is connected with a nitrogen injection pipeline. During work, prepared slurry is fed into the stirring device (2) to be fully mixed and then fed into the proportioning mixer (3), negative pressure is produced on the part and a foaming agent is sucked in proportion, the materials are mixed through the mixer (4) and then fed into the foam maker (6), and the produced foam is distributed through the foam distributor (7) for fire extinguishing at the goaf. The system is convenient and fast to assemble and has high foam making efficiency, the foam distributor is additionally arranged, the foam injection efficiency of the goaf is improved, and the problem of difficulty in positioning of a spontaneous combustion point of the coal at the goaf can be avoided.
Description
Technical field
The present invention relates to a kind of colliery many components of underground movable froth fire extinguishing system, be particularly useful for the anti-fire extinguishing of coal mine gob.
Background technology
Under coal mine, coal spontaneous combustion mainly occurs in the places such as coal column of goaf, pressure break, and is wherein serious with goaf.In order to prevent and treat spontaneous combustionof coal, extensively adopt the technology such as water filling, grouting, sprinkling retardant, notes noble gas both at home and abroad, adopted more widely again in recent years foam perfusion preventing and extinguishing fire technology.But the coal spontaneous combustion point of origin does not have rule, and mine goaf is the space of a huge solid, and the existing technology of utilizing foam to prevent and treat coal spontaneous combustion can play certain prevention effect, but also has weak point.
Summary of the invention
In view of the deficiency of existing device, the invention provides a kind of simple in structure, assembling flexibly, to the goaf coal spontaneous combustion multicomponent froth fire extinguishing system with good prevention effect on fire.
A kind of colliery of the present invention many components of underground movable froth fire extinguishing system, it comprises mixing plant, proportioner, blender, force (forcing) pump, foam maker and foam dispenser, also comprises the foaming agent tank that is connected with proportioner; Be connected with pipeline by flange in turn between described mixing plant, proportioner, blender, force (forcing) pump, foam maker and foam dispenser.The described grouting pipe that is connected with mixing plant is provided with valve; Described proportioner is provided with valve with the pipeline that the foaming agent tank is connected; The described admission line that is connected with foam maker is provided with valve; Add pressure meter between described blender and force (forcing) pump.
The present invention has used foam dispenser, the sub-thread foam stream can be separated into the multiply foam stream, and when the goaf coal spontaneous combustion prevented and treated, charging efficiency was high.
The present invention has following beneficial effect:
1) the whole system member is small and exquisite flexible, and each parts are by the flange connections road, and it is convenient to assemble, the cleaning after use and easy to maintenance;
2), due to the adding of foam dispenser, can improve charging efficiency while carrying out the foam perfusion in goaf.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention.
In figure: 1-grouting pipe, 2-mixing plant, 3-proportioner, 4-blender, 5-force (forcing) pump, 6-foam maker, 7-foam dispenser, 8-foaming agent tank, 9-valve, 10-pressure meter, 11-flange, 12-foamed pipe pipeline joint
The specific embodiment
Shown in Figure 1, the present invention includes mixing plant 2, proportioner 3, blender 4, force (forcing) pump 5, foam maker 6 and foam dispenser 7, also comprise the foaming agent tank 8 that is connected with proportioner 3; Be connected with pipeline by flange in turn between described mixing plant 2, proportioner 3, blender 4, force (forcing) pump 5, foam maker 6 and foam dispenser 7.
The described grouting pipe 1 that is connected with mixing plant 2 is provided with valve 9, the pipeline that described proportioner 3 is connected with foaming agent tank 8 is provided with valve 9, the described admission line that is connected with foam maker 6 is provided with valve 9, adds pressure meter 10 between described blender 4 and force (forcing) pump 5.
during system works, open the valve 9 on grouting pipe 1, slurries enter mixing plant 2 fully to be mixed, to avoid the slurries deposition in the pipeline transport process for a long time, after fully being mixed into proportioner 3, open be connected with foaming agent tank 8 valve 9 on pipeline of proportioner 3, the negative pressure of crossing proportioner 3 generations by slurry stream quantitatively sucks foaming agent and preliminary the mixing, entering blender 4 with the mixed slurries of foaming agent further mixes, can read the force value of pressure meter 10 this moment, and open 5 pairs of mixed serums of force (forcing) pump and pressurize, when the slurries after pressurization enter foam maker, open the valve 9 on the admission line that is connected with foam maker 6, so far system starts foaming, produce foam and be used for the anti-fire extinguishing of goaf perfusion after foam dispenser 7 distributes.
Above-described embodiment of invention is only for example of the present invention clearly is described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give all embodiments exhaustive.Everyly belong to the row that apparent variation that technical scheme of the present invention extends out or change still are in protection scope of the present invention.
