Anti-reburning environment-friendly power transmission line forest fire extinguishing agent

Abstract

The invention discloses an anti-reburning environment-friendly power transmission line forest fire extinguishing agent. The anti-reburning environment-friendly power transmission line forest fire extinguishing agent comprises the following components in parts by weight: 5-20 parts of ammonium carbonate, 10-45 parts of ammonium polyphosphate, 10-30 parts of sodium silicate, 1-10 parts of a foaming agent, 0.5-5 parts of polyethylene glycol, 1-5 parts of a thickening agent, 4-10 parts of a composite anti-freezing agent and 55-80 parts of water, wherein the foaming agent is selected from one of alkylethoxylate carboxylate, an imidazoline amphoteric surfactant and a biological surfactant; the composite anti-freezing agent is a compound which is prepared by compounding inorganic salt and polyhydric alcohol according to a mole ratio of (1 to 3)-(1 to 9). All the raw materials of the anti-reburning environment-friendly power transmission line forest fire extinguishing agent are environment-friendly materials, so that the fire extinguishing agent is free of fluorine compound, toxicity, smell and pollution; a fire retardant is added into the fire extinguishing agent, so that the fire extinguishing agent is capable of effectively preventing the fire from spreading and is high in fire extinguishing efficiency; the environment-friendly surfactant serves as the foaming agent, so that the fire extinguishing agent is high in foaming performance and is capable of effectively isolating contact between the combustion material and the air and accelerating the fire extinguishing speed; the anti-freezing agent is compounded by the inorganic salt and polyhydric alcohol, so that the freezing point of the fire extinguishing agent is reduced to be -30 DEG C.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to a fire extinguishing agent, in particular to an anti-recombustion environment-friendly transmission line mountain fire fire extinguishing agent. Background technique [0002] With the continuous expansion of China's industrial scale and the development of smart grids, higher and higher requirements are put forward for the safety and reliability of power supply. Mountain fire is a kind of disaster accident with strong suddenness, rapid spread and great difficulty in fighting. In recent years, there have been more and more tripping and blackout accidents caused by wildfires on transmission lines, which seriously threaten the safe and stable operation of transmission lines, especially UHV transmission lines. In order to quickly extinguish mountain fires on power transmission lines, it is necessary to comprehensively select fire extinguishing agents based...

Problems solved by technology

Water is the most economical natural fire extinguishing agent, but its fire extinguishing efficiency is low and the consumption is large. For the fire scene where the mountain fire occurs with inconvenient transportation, the vehicle is difficult to approach, and the fire cannot be extinguished in a timely and effective manner; dry powder fire extinguishing agent, foam fire extinguishing agent and Carbon dioxide fire extinguishing agent, whose fire extinguishing principle is to cover and isolate air, is usually suitable for indoor conventional fire extinguishing. It has limited fire extinguishing ability for large-scale open transmission line mountain fires in the wild. It is very easy to re-ignite after the fire is extinguished. fire extinguishing requirements
