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
Ammonium bicarbonate is used as the main raw material of the fire extinguishing agent. During the fire extinguishing process, a large amount of ammonia gas will be released, which pollutes the air in the mine and is not conducive to the health of operators.

Embodiment Construction

[0050] Below in conjunction with embodiment the present invention will be further described:

[0051] 1. The batching of the perlite reticulated gel foam mud fire extinguishing agent consists of the following components by weight percentage: 38% of perlite composite flame retardant foaming agent, 20% of inorganic fiber spray cotton mixture and 42% of water.

[0052] The production method of the perlite reticulated gel foam mud fire extinguishing agent: input the ingredients of the perlite reticulated gel foam mud fire extinguishing agent into the rake mixer, and stir at a high speed to form the perlite reticulated gel foam mud fire extinguishing agent. Fire extinguishing agent, the speed of the rake mixer is controlled at 2400-2800 rpm, and the stirring time is controlled at 15 minutes.

[0053] 2. Perlite composite flame retardant foaming agent ingredients are composed of the following components by weight percentage: perlite composite flame retardant foaming agent paste 48%,...

Abstract

The invention discloses a fire extinguishing agent for perlite reticulated gel foam mud. , expanded perlite powder, coal gangue powder, sodium alginate and water. Input the ingredients of the perlite reticulated gel foam mud fire extinguishing agent into the rake type mixer, and stir at a high speed to form the perlite reticulated gel foam mud fire extinguishing agent. The reticular gel foam slurry is sprayed onto the burning coal seam by an inorganic fiber sprayer, which is conducive to the formation of an integral reticular gel foam slurry film in the process of fire prevention and extinguishing, which always covers and adheres to the surface of the mine layer and quickly isolates the 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 retardancy and fire prevention. The perlite mesh gel foam mud fire prevention agent is suitable for fire prevention in coal mines, mine operation areas and forests.

Description

technical field [0001] The invention relates to an anti-fire extinguishing agent, in particular to a perlite reticulated 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. [0004] Chinese Patent Publication No. CN 102614615A, publication date: August 01, 2012, titled "a composite foam fire extinguishing agent for coal mine undergrou...
