Gasified ash gel fire preventing and extinguishing material, use method and application thereof

Abstract

The invention discloses a gasified ash gel fire preventing and extinguishing material as well as a use method and an application thereof, and belongs to the technical field of fire preventing and extinguishing materials. The fire preventing and extinguishing material is prepared from the following raw material components in percentage by mass: 0.25%-0.5% of a dispersion suspending agent, 1%-1.66% of a gelling agent, 1%-2% of a coagulation accelerator and the balance of ash slurry, wherein the ash slurry is prepared by mixing gasified ash and water, the water-ash mass ratio of the gasified ash to the water is 2:(0.4-2), and meanwhile, the invention further provides the use method and the application of the material. According to the fire preventing and extinguishing material, the optimal material ratio is developed, the fire preventing and extinguishing level of a goaf is comprehensively improved, the fire preventing and extinguishing cost is greatly reduced, the reliability, pertinence and effectiveness of the fire preventing and extinguishing technology are improved, and huge economic benefits and social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of anti-fire extinguishing materials, in particular to a gasification ash gel anti-fire extinguishing material, its use method and application. Background technique [0002] my country is rich in coal resources, with large and small coal fields all over the country. Coal is also the main energy source in my country at present, occupying a dominant position in the energy structure. With the rapid development of coal mining technology, the number of newly built and expanded mines and the increase of mining intensity and mining depth, the problem of mine fire prevention and extinguishing is particularly prominent, and the form of coal seam spontaneous combustion fire prevention and control is becoming more and more severe. According to past experience, as long as it is a coal seam face prone to spontaneous combustion, all existing fire prevention technical measures are blindly adopted. Chemical agent, nitrogen...

AI Technical Summary

Problems solved by technology

The network skeleton structure of the inorganic gel fire extinguishing agent is an inorganic material with good thermal stability. It slowly loses water at high temperature to generate water vapor and absorb a large amount of heat, thereby effectively reducing the temperature. The colloid is non-toxic and harmless, and does not pollute the environment. The equipment is non-corrosive, and the gelation process is simple, which is convenient for on-site application, but the cost is relatively high

The polymer gel fire extinguishing agent adds a small amount of certain hydrophilic materials (base materials) to the slurry such as loess, fine sand, mineral powder, mud sand, and fly ash to increase the consistency of the slurry and make it more uniform macroscopically. Thixotropy, but if the concentration of the mud is too large, the fluidity will be poor, and the pipeline will be easily blocked, and because a large amount of fly ash and loess are required for preparation, there is a certain transportation cost, so the greater the concentration, the higher the cost high
