Abstract

The invention discloses a hydrocarbon flammable liquid flowing fire extinguishing agent which is characterized by comprising the following components in percentage by weight: 1.5%-15% of a foaming agent, 2%-10% of a fluorine surfactant, 4%-15% of an emulsifier, 0.2%-5% of a stabilizer, 3%-15% of a cosolvent, 5%-15% of an antifreeze agent, 0.5%-3% of a flame retardant, 0.1%-1% of a preservative andthe balance of water. The hydrocarbon flammable liquid flowing fire extinguishing agent has the advantages that through the triple effects of fuel emulsification, water film forming isolation, foam covering and the like, the synergistic fire extinguishing is realized, and the problems of low fire extinguishing speed, poor cooling effect, poor anti-reburning effect and the like of flammable liquidflowing fire in the prior art are solved.

Description

technical field [0001] The invention belongs to a fire extinguishing agent, in particular to a fire extinguishing agent for hydrocarbon flammable liquid flowing fire. Background technique [0002] With the rapid development of my country's social economy, petrochemical fire accidents have gradually become more frequent in recent years. In 2010, an explosion occurred in the Dalian oil pipeline, causing the rupture of the crude oil pipeline and rapidly forming more than 60,000m 2 A total of more than 1,000 tons of foam fire extinguishing agents were used in this fire fighting. Hydrocarbon liquids such as crude oil, gasoline, and diesel oil are flammable and explosive, with high combustion calorific value, rapid fire spread, and large storage capacity. Once leaked and a flowing fire occurs, it will cause serious damage to other fuel storage tanks and fire-fighting facilities. havoc. After the fire of these hydrocarbon liquid storage tanks occurs, once a large area of ​​flowi...
