Extinguishment product using clear gas as sponging agent as well as production method and fire-extinguishing system

Abstract

The present invention relates to a fire extinguishing product which consists of clean gas extinguishing agent and fire foam and uses clean gas as vesicant and a manufacturing method and a fire extinguishing system thereof. A gas foam fire extinguishing product consisting of the clean gas extinguishing agent and the fire foam uses the clean gas extinguishing agent as a foaming medium of the fir foam. A foam liquid supply device is communicated with a gas foam mixer by a pipeline. The clean gas extinguishing agent is communicated with the gas foam mixer by the pipeline. The gas foam mixer outlet is communicated with a foam generator by the pipeline. The present invention has the advantages of solving the problem that flammable liquid with low boiling point is difficult for extinguishing fire and solving the technical problem that people want to solve but do not solve for a long time.

Description

technical field [0001] The invention relates to a fire extinguishing product composed of a clean gas fire extinguishing agent and a foam fire extinguishing agent and uses clean gas as a foaming agent, a production method and a fire extinguishing system, belonging to the field of fire fighting products and fire fighting system manufacturing. Background technique [0002] 1. HFC-227ea is a clean gas fire extinguishing agent. [0003] The chemical name of HFC-227ea is heptafluoropropane, and the chemical formula is CF3CHFCF3. It is a clean gas fire extinguishing agent that meets the requirements of the NFPA-200 specification formulated by the National Fire Protection Association (NFPA). It is characterized by "non-conductive, volatile or gaseous fire extinguishing agent. , leaving no residue during use". At the same time, HFC-227ea clean gas fire extinguishing agent is harmless to the environment, has a short storage period in nature, high fire extinguishing efficiency and is ...

AI Technical Summary

Problems solved by technology

Carbon dioxide fire extinguishing is mainly suffocating, but it is difficult to extinguish smoldering substances, especially when the oxygen content in the air in the combustion area is greater than 12%, it is difficult to extinguish the combustion; secondly, carbon dioxide cannot extinguish lithium, sodium, potassium, magnesium, The fires of aluminum, antimony, titanium, cadmium, platinum, plutonium and other metals and their oxides cannot be used to extinguish fires of oxygen-containing chemicals such as nitrocellulose, celluloid, gunpowder, etc.; The air is wrapped in the foam. Under the effect of high temperature, the air in the foam does not have the effect of extinguishing the fire of the high-temperature combustible substance, but plays the role of supporting the combustion.
