Abstract
The invention discloses a complex foam extinguishing agent for a coal mine and belongs to the technical field of fire prevention and extinguishing. The extinguishing agent is prepared from the following raw materials: main materials are 40 to 60 percent aqueous solution of ammonium bicarbonate or sodium bicarbonate and concentrated sulfuric acid in a solute mass ratio of 2:1-3:1, and auxiliary materials are a stabilizer and a foamer, wherein the auxiliary materials are 0.1 to 2 percent of the total weight of the main materials. Through a test, the extinguishing agent has the foaming coefficient of 20-200 and the foam stabilizing time of more than or equal to 2.5 hours. According to the foam extinguishing agent, the foam of inert gas carbon dioxide is applied to fire prevention and extinguishing of the coal mine, and the foam is diffused in a fire area and fills a fire space, so that the oxygen concentration in the fire area is rapidly reduced, fire is extinguished due to oxygen deficiency in the fire area, temperature is reduced and a fire extinguishing effect is good. The technology also can be applied to coal bed transformation, CO2 foam is easily absorbed by coal to displace partial methane, the recovery ratio of coal seam gas is improved, and CO2 is acid to reduce the generation of secondary precipitates, so that a gas drainage effect is improved. The complex foam extinguishing agent is simple and feasible, and low in cost.
Description
Technical field
The present invention relates to a kind of fire foam, is the efficient stable type bubble two phase complex fire foams that are used for preventing and extinguishing fire of coal mine specifically.
Background technology
At present, a large amount of inert gas for fire extinguishing modes of using in the colliery, inert gas for fire extinguishing agent commonly used both at home and abroad has nitrogen and carbon dioxide.Pass through CO
2The CO that generator (group) reacts two kinds of chemical raw materials to produce
2, to underground goaf or driving face perfusion, use CO by the road
2Enrich airtight ignition zone, the effect of play heat absorption, lower the temperature, suffocate, putting out a fire.The advantage of this scheme is to use not electricity consumption in the process, and aerogenesis concentration is high, and the aerogenesis temperature is low, helps absorbing and cooling temperature, does not produce secondary pollution.If carbon dioxide is converted into carbon dioxide foaming, foam coverage makes the material and the air insulated of firing on the burning article, and reduces temperature, and the fire extinguishing effect can be better.The prior art of the carbon dioxide fire prevention and extinguishment of colliery use at present mainly is a carbon dioxide; If replace gas with lazy bubble; Flame-retarding fire-extinguishing and the anti-fire extinguishing of cooling dual purpose but can realize suffocating; Therefore do not have the carbon dioxide foaming good extinguishing effect, and foam property there is appreciable impact to putting the fire extinguishing effect, though existing data has proposed to improve the index of carbon dioxide foaming stability; But be mainly used in fracturing technique in the oil, improve the method for carbon dioxide foaming multiple when also not proposing to strengthen carbon dioxide foaming stability.
Summary of the invention
It is high to the purpose of this invention is to provide a kind of foam output, good stability be applicable to complex fire foam under the coal mine.
The objective of the invention is to realize: a kind of complex fire foam that is used under the coal mine through following technical proposals; It is characterized in that: processed by following raw materials according: major ingredient is that concentration is 40% ~ 60% carbonic hydroammonium or the sodium bicarbonate aqueous solution and the concentrated sulfuric acid; Pressing solute mass ratio 2:1 ~ 3:1 mixes; Auxiliary material is stabilizing agent and blowing agent, and said supplementary product consumption is a major ingredient gross weight 0.1% ~ 2%.
Described stabilizing agent is any one or a few the combination in hydroxypropyl guanidine glue, lauryl alcohol, ZG-80, CMC, the xanthans.
Described blowing agent is any one or a few the combination among AOS, K12, fluorocarbon surfactant, the ZGFF.
Described stabilizing agent is selected lauryl alcohol, ZG-80 mixture for use, and the two mixing quality is than being 4:1, and described blowing agent is selected AOS for use, and AOS accounts for 0.6% of major ingredient gross weight.
Can also add the anticorrisive agent of major ingredient gross weight 0.05% as required.
Beneficial effect of the present invention: complex fire foam of the present invention; In the carbon dioxide that major ingredient adopts carbonic hydroammonium or sodium bicarbonate aqueous solution and strong sulfuric acid response to produce, add the auxiliary material additive that blowing agent combines with stabilizing agent, make carbon dioxide fire prevention and extinguishment effective more economically.Stabilizing agent has thickening property, and the effect of solubilising is arranged, and reduces the repulsive force between the active agent molecule, can improve the adhesion strength of foam; Through improving the discharge opeing speed that viscosity is slowed down foam, prolong half-life; Blowing agent adopts the good surfactant of gas release, is used to make the raw material foaming and improves 20 ~ 200 times of coefficient of foamings, foam stabilization time >=2.5h.Gas foaming of the present invention is satisfactory for result, and the gas coefficient of foaming is compatible with stability.Have intersolubility good, the preparation simple; Security performance is good, nontoxic, free from extraneous odour.This technology also can be applicable to coal seam transformation, CO
2Foam is prone to be absorbed by coal body, replaceablely goes out part methane, improves the recovery ratio of coal-bed gas, CO
2Be acid, can reduce secondary sedimentary generation, thereby improve the gas drainage under suction effect.
