Fire extinguishing system with combined effect of clean chemical gas and fine water mist

Abstract

The invention discloses a fire extinguishing system with combined effect of clean chemical gas and fine water mist. The fire extinguishing system is characterized by comprising a compressed air storage tank, a fine water mist and water storage tank, a clean chemical gas fire extinguishing agent storage tank, a fire extinguishing agent proportional mixer and an atomizing spray head, wherein the compressed air storage tank is respectively communicated with a gas inlet of the water mist and water storage tank and a gas inlet of the clean chemical gas fire extinguishing agent storage tank by an air pressure-reducing valve through a pipeline; a water outlet of the water mist and water storage tank and a fire extinguishing agent outlet of the clean chemical gas fire extinguishing agent storage tank are respectively communicated with an inlet of the fire extinguishing agent proportional mixer by a pipeline; an outlet of the fire extinguishing agent proportional mixer is connected with the atomizing spray head by a pipeline. The fire extinguishing system disclosed by the invention realizes the effective combination of two fire extinguishing ways of clean chemical gas fire extinguishing and water mist fire extinguishing, not only can realize the efficient, quick and clean fire extinguishing, but also can effectively lower the temperature of a fire scene, and can lower the concentrations of poisonous and corrosive gases such as HF in a fire extinguishing space.

Description

technical field [0001] The invention relates to a fire extinguishing system in which a clean chemical gas fire extinguishing agent and fine water mist act together, and belongs to the field of fire fighting system manufacture. Background technique [0002] Because of the destruction of the atmospheric ozone layer, the use of halon fire extinguishing agents is banned worldwide, and clean chemical gas fire extinguishing agents such as heptafluoropropane, trifluoromethane, perfluorohexanone, and bromofluoropropene are used as alternatives due to their high efficiency, cleanliness, and environmental protection. and many other advantages. [0003] After the clean chemical gas fire extinguishing agent applied to the fully submerged type is released into the closed space, the fire extinguishing agent can quickly inhibit the spread of flames through physical and chemical methods. The physical gasification stage absorbs a large amount of heat, and the chemical reaction generates a la...

AI Technical Summary

Problems solved by technology

HF is a poisonous strong acid gas, which will seriously corrode metal equipment and electronic equipment in a humid environment, and will cause irreparable damage to firefighters on the fire site after being inhaled.
