Abstract
The present invention belongs to the field of fire extinguishing technology, and is especially one kind of fire extinguishing coagulant-thickener of caustic sludge colloid. The fire extinguishing coagulant-thickener consists of superfine caustic sludge powder, linear polymer material containing hydrophobic hydroxyl group or carboxyl group, and inorganic silica and alumina material. The fire extinguishing coagulant-thickener is mixed with fire extinguishing base material to form colloid, and may swell after being mixed with water to form mixture slurry with great heat absorption and high heat stability. It has excellent use effect in preventing spontaneous ignition of coal bed and extinguishing fire of coal bed. The present invention uses industrial waste as main material and has rich material source and low cost.
Description
Technical field
The invention belongs to fire extinguishing prevention technique field, be specifically related to a kind of colloid fire extinguishing coagulant-thickener that is used for the colliery fire extinguishing.
Background technology
Coal-mine fire adopts that the colloid fire extinguishing has that blow-off velocity is fast, efficient is high, be difficult for the characteristics of resume combustion after the fire extinguishing.Mine fire colloid fire extinguishing at present is general adopts aqueous solution (or mixes with the slurries of loess etc.) the back injection primer sector of liquid base-material and solid coagulant, thereby mixture reaches the purpose of fire extinguishing at primer sector formation gel.The colloid extinguish material that uses generally adopts silica dioxide gel, every cubic metre interpolation material is 80～150kg, it is bigger to add material usage, cost is higher, need be transported under the mine adding material in a large number during fire extinguishing, because traffic condition is poor under the coal mine, this material has bigger limitation in fire extinguishing.Also useful pulverulent material and water are mixed into colloid, put out a fire, though these colloids have certain flowability, its cost is also than higher.Have the colliery of spontaneous combustion danger that the ground grouting system is mostly arranged, general concentration of slurry is big more, and the fire extinguishing effect is good more, but high concentration slurries free settling causes pipeline blockage easily, and the grouting operation that influence is emergent, concentration of slurry can reduce or influence the fire extinguishing effect again when low.
Summary of the invention
The objective of the invention is to propose a kind ofly both can make the slurries thickening, can improve suspension again, and can be controlled at presumptive area generation gelling, and colloid fire extinguishing coagulant-thickener with low cost, good extinguishing effect, to overcome the deficiency of existing colloid fire extinguishing solid coagulant.
The colloid fire extinguishing coagulant-thickener that the present invention proposes, be the mechanism of utilizing alkaline residue self halide to suppress to burn, hydrophily linear polymeric material and high suction sial inorganic material by alkaline residue micro mist and hydroxyl, carboxyl mix, and each component consumption by weight ratio is as follows:
Alkaline residue micro mist 120～160,
Linear polymeric material 0.3～0.6,
High suction sial inorganic material 12～16.
The preparation method of colloid provided by the invention fire extinguishing coagulant is as follows: with the alkaline residue raw material dry, levigate processing handles, then with linear polymeric material and high suction sial inorganic material by usage ratio mixing in batch mixer, get final product metering packing.
Among the present invention, used linear polymeric material can be the copolymer of acrylic acid and vinyl acetate alcohol ester.
Fire extinguishing coagulant-thickener of caustic sludge colloid provided by the invention mixes the back with fire extinguishing base-material (flyash or loess etc.) slurries and forms colloid, the weight proportion of each component of colloid is as follows: flyash 600～800kg in every cubic metre of colloid, alkaline residue micro mist 120～160kg, linear polymeric material 0.3～0.6kg, sial inorganic material 12～16kg.
Good effect of the present invention is:
1, in flyash, loess slurries fire extinguishing base-material, adds caustic sludge colloid coagulant-thickener extinguish material of the present invention, this coagulant-thickener is met water-soluble bloated back and is formed flyash or loess particle bridge joint, and then generation network structure, constraint more freedom water, thus solid matters such as suspension flyash or loess are made mixture slurry.The caustic sludge colloid coagulant-thickener increases the mixture slurry denseness, also improves the suspension of slurries simultaneously, improves the fluid injection fire-fighting effect.
2, the mixture slurry made of coagulant-thickener of the present invention and flyash or loess base-material is inner can a large amount of moisture content of savings, and when meeting high temperature, the slurry internal temperature can very fast rising, is not easy bumping, has good heat endurance.When temperature is elevated to more than 100 ℃, composite slurry still has certain rigid, plays the effect of good starvation.
3, the present invention utilizes that muriatic resistance turns usefulness in the alkaline residue, can stop the chain reaction that goes round and begins again in the combustion process, further reaches good fire extinguishing effect.
4, surrender takes place and can not ftracture in the mixture slurry that adopts the present invention the to make back of condensing under bigger external force effect, and recovers under the effect of reverse power, and it is low to have overcome general colloidal materials intensity, the external force effect down can be broken can not physical restoration deficiency.
5, because the present invention is raw material with the industrial waste alkaline residue, it is convenient to use, the cheapness of getting, the external correlation technique of ratio of material dosage low 20% when using the present invention to put out a fire, have only about 1/10 of conventional grouting fire extinguishing, the fire extinguishing cost is 70% of grouting fire extinguishing, is 45% of external similar technology.
6, technology of the present invention is simple, and is easy to operate, promptly can be used to put out coal bed fire, also can be used to put out solid fire, well-head fire, forest fires etc. such as coal yard.
The specific embodiment
Coagulant-thickener is relevant with the concentration of the slurry of being prepared with the anti-extinguishing property of the mixture slurry that flyash or loess base-material are made, concentration is high more, the heat absorption of slurry is bigger than more, and the fire extinguishing effect is good more, below in conjunction with specific embodiment the present invention is further described:
Embodiment: 1, preparation can be used for the slurry of working face of coal seam fire prevention, in every cubic metre of mixture slurry:
Particle mean size is less than flyash or the loess 600kg of 1mm
Alkaline residue micro mist 120kg
Linear polymeric material 0.3kg
High suction sial inorganic material 12kg
Embodiment 2, preparation working face of coal seam fire extinguishing slurry, in every cubic metre of mixture slurry:
Particle mean size is less than flyash or the loess 700kg of 1mm
Alkaline residue micro mist 160kg
Linear polymeric material 0.6kg
High suction sial inorganic material 16kg
Embodiment 3, preparation working face of coal seam fire extinguishing slurry, in every cubic metre of mixture slurry:
Particle mean size is less than flyash or the loess 800kg of 1mm
Alkaline residue micro mist 140kg
Linear polymeric material 0.4kg
High suction sial inorganic material 14kg
Above-mentioned sial inorganic material can adopt superfined flyash, and the linear polymeric material adopts the copolymer of acrylic acid and ethene acetate alcohol ester.
The fire extinguishing colloid for preparing in the above-mentioned example all has good performance, and the fire extinguishing effect is very good.
