Embodiment 1

[0029] Such as figure 2 As shown, this embodiment provides a clean non-pressure storage fire extinguisher 100, which mainly includes a fire extinguishing agent storage tank 1 and an eruption power device 2, wherein the fire extinguishing agent storage tank 1 is filled with a liquid or gaseous fire extinguishing agent 3. The fire extinguishing agent 3 of the embodiment is preferably fluid perfluorohexanone.

[0030] The side wall of the fire extinguishing agent storage tank 1 is provided with at least one spout 11, and the spout 11 is closed by a first safety diaphragm 12, so that the perfluorohexanone fire extinguishing agent 3 is stored in a closed environment, which is suitable for long-term storage. The first safety diaphragm 12 is in the shape of a film and will rupture when reaching a critical pressure value. Based on this, the present embodiment uses the eruption power device 2 to provide pressurization, so that the air pressure in the fire extinguishing agent storage ...

Embodiment 2

[0042] refer to image 3 As shown, this embodiment provides another clean non-pressure storage fire extinguisher 200. The structure of the clean non-pressure storage fire extinguisher 200 is basically the same as that of the fire extinguishing device shown in Embodiment 1. The main difference is that the embodiment The fire extinguishing agent in one is fluid perfluorohexanone, and the fire extinguishing agent 3 of this embodiment is several perfluorohexanone capsules packaged into small particles, and these perfluorohexanone capsules are squeezed by high temperature and high pressure gas After that, it can also be sprayed out through the nozzle 11 to implement fire extinguishing.

[0043] Another difference is that since the fire extinguishing agent storage tank 1 is filled with full perfluorohexanone capsules, and there are gaps between the perfluorohexanone capsules, the pre-stored resistance in the pressure chamber 212 as the pressurization power The combustible substance...

Abstract

The invention relates to a clean type non-pressure-storage fire extinguisher. The clean type non-pressure-storage fire extinguisher comprises a fire extinguishing agent storage tank and an eruption power device, and the fire extinguishing agent storage tank is filled with a fire extinguishing agent; at least one nozzle is formed in the side wall of the fire extinguishing agent storage tank; the eruption power device comprises a power pipeline and a power piston suitable for moving in the power pipeline, the power pipeline is divided into a gas generating cavity and a gas compressing cavity, a gas generating agent is arranged in the gas generating cavity, flame-retardant substances are pre-stored in the gas compressing cavity, and an eruption opening communicating with the fire extinguishing agent storage tank is formed in the gas compressing cavity; and high-pressure gas generated after the gas generating agent is triggered pushes the power piston to move towards the gas compressing cavity and extrudes the flame-retardant substances, and the flame-retardant substances enter the fire extinguishing agent storage tank after being pressurized, so that the fire extinguishing agent is sprayed outwards from the nozzles. The fire extinguishing agent is free of pollution and can be applied to most fire extinguishing occasions, and therefore the market requirement is effectively met.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a clean non-pressure storage fire extinguisher. Background technique [0002] With the increasingly strict restrictions on the use of traditional halon, heptafluoropropane, hexafluoropropane and other gaseous fire extinguishing agents, perfluorohexanone fire extinguishing agent with good environmental performance has been used more and more widely. It has low fire extinguishing concentration and high fire extinguishing efficiency. High, high safety factor, non-conductive, no residue, etc., suitable for fire protection places where it is not suitable to use other fire extinguishing agents to fight the fire and there is no large secondary pollution after fire extinguishing, such as big data centers, computer rooms, power distribution rooms, cultural relics Archives, aviation and ship engine compartments, etc. [0003] Since perfluorohexanone is a clear, colorless, ...
