Sludge mesh gel foam mud fire extinguishing agent

Abstract

The invention discloses a sludge reticulated gel foam mud fire-extinguishing agent. The main point of the technical solution is that it is composed of a sludge composite flame-retardant foaming agent, attapulgite clay powder with the function of purifying air, and inorganic fiber sprayed cotton. , sludge powder, coal gangue powder, expanded perlite powder, sodium alginate and water. The ingredients of the sludge reticulated gel foam mud fire-extinguishing agent are input into the plow-rake mixer, and stirred at high speed to become the sludge reticulated gel foam mud fire-extinguishing agent. The reticulated gel foam slurry is sprayed to the burning coal seam by an inorganic fiber sprayer, which is conducive to the formation of an integral reticulated gel foam mud film during the fire-fighting process, which always covers and adheres to the surface of the coal seam and quickly isolates combustion. The contact between the coal seam and the air prevents the coal mine from continuing to burn, avoids the re-ignition of the coal seam, and achieves the purpose of flame retardant and fire prevention.

Description

technical field [0001] The invention relates to an anti-fire extinguishing agent, in particular to a sludge reticular gel foam mud anti-fire extinguishing agent. Background technique [0002] Fully mechanized top-coal caving mining has the advantages of high yield, high efficiency, and low consumption, and has been widely used in many coal production bases in my country. However, due to the high mining intensity of this coal mining method, there is a lot of residual coal left in the goaf, the height of the fall is large, and the air leakage is serious. A series of problems such as fire, gas, and dust that are difficult to solve often occur, especially fire. [0003] Foam fire extinguishing agents are divided into chemical foam, air foam, fluoroprotein foam, aqueous film-forming foam and alcohol-resistant foam.

AI Technical Summary

Problems solved by technology

[0005] The disadvantages of the above-mentioned patents are: although the foam multiple of the fire extinguishing agent can reach 20 to 200 times, and the foam stability time is ≥ 2.5 hours, it can only make the "inert gas carbon dioxide foam spread in the fire zone and fill its space in a short time." , so that the oxygen concentration in the fire area drops rapidly, causing the fire area to suffocate due to lack of oxygen", it cannot really isolate the contact between the burning coal seam and the air, prevent the coal mine from continuing to burn, avoid the re-ignition of the coal seam, and achieve flame retardancy and fire prevention. Purpose

Many sludge storages are used overdue or overloaded, or even operated in violation of regulations, which poses a great potential safety hazard to the sludge storage and poses a serious threat to the property and life safety of people in the surrounding areas.
