Embodiment 1

[0029] This embodiment is used to illustrate the structure and use method of the halogenated hydrocarbon gas fire extinguishing system with safety additives according to the present invention.

[0030] The halogenated hydrocarbon gas fire extinguishing system method consists of a halogenated hydrocarbon fire extinguishing agent 1, a halogenated hydrocarbon fire extinguishing agent tank 2, a water tank 3, a pressure source 4, a one-way valve 5, a safety additive mixer 6, a safety additive 7, a fire extinguishing Pipeline 8, charged fire extinguishing nozzle 9 forms.

[0031] The safety additive is mixed with a halogenated hydrocarbon fire extinguishing agent by a mechanical pump-in proportional mixer. The pressure source 4 of the halogenated hydrocarbon gas fire extinguishing system adopts a pump set. When extinguishing a fire, the pressure source 4 extracts the halogenated hydrocarbon fire extinguishing agent 1 in the halogenated hydrocarbon fire extinguishing agent tank 2, p...

Embodiment 2

[0033] This embodiment is used to illustrate the composition of the halogenated hydrocarbon gas fire extinguishing system with safety additives according to the present invention.

[0034] In the halogenated hydrocarbon gas fire extinguishing system described in embodiment 1:

[0035] The halogenated hydrocarbon fire extinguishing agent is a mixture of 2-bromopentafluoropropene and 1-bromo-2,3,3,3-tetrafluoropropene in a ratio of 4:6. The safety additive is an aqueous solution of a mixture of sodium carbonate and triethylamine, and the aqueous solution contains 2% of sodium carbonate and 0.1% of triethylamine.

[0036] The safety additive is mixed with a halogenated hydrocarbon fire extinguishing agent by a mechanical pump-in proportional mixer. The mixing ratio of the safety additive to the halogenated hydrocarbon fire extinguishing agent is 1:50.

Embodiment 3

[0038] The difference between this embodiment and embodiment 2 is:

[0039] The safety additive is 2% sodium carbonate aqueous solution.

Abstract

The invention relates to a fire extinguishing tool, and in particular, discloses a halohydrocarbon gas fire extinguishing system with safety additives. The fire extinguishing system comprises halohydrocarbon fire extinguishing agents and the safety additives, and a safety additive mixer capable of mixing the halohydrocarbon fire extinguishing agents with the safety additives in proportion, whereinthe safety additives are inorganic alkali metal weak-alkalinity salt and/or water solution of organic weak-alkalinity compounds. The inorganic alkali metal weak-alkalinity salt and/or the water solution of the organic weak-alkalinity compounds are adopted as the safety additives to realize efficient absorption of acid poisonous gas generated by the halohydrocarbon fire extinguishing agents. Meanwhile, the inorganic alkali metal weak-alkalinity salt contains alkali metal ions, and can absorb combusted free radicals, so that the overall fire extinguishing effect of the fire extinguishing systemis further improved. The fire extinguishing system is suitable for wide application to the electric fire prevention for transformers, cable tunnels, valve halls and power distribution chambers.

Description

technical field [0001] The invention relates to a fire extinguishing tool, in particular to a halogenated hydrocarbon gas fire extinguishing system with safety additives. Background technique [0002] Halogenated hydrocarbon gas fire extinguishing agent is a high-efficiency gas fire extinguishing agent, which has the advantages of high fire extinguishing efficiency, strong insulation ability, live fire extinguishing, no residue after fire extinguishing, and little impact on the atmospheric ozone layer. However, the halogenated hydrocarbon gas fire extinguishing agent will decompose and produce acidic and toxic gases such as hydrogen fluoride during the fire extinguishing process, which is very harmful to the human body. Therefore, there is an urgent need to develop a safe halogenated hydrocarbon gas fire extinguishing system to provide protection for the safety of personnel in a fire extinguishing environment. Contents of the invention [0003] In order to solve the probl...
