Embodiment 1

[0045] figure 1 Shown is a portable low-resistance two-phase flow water mist fire extinguishing device, including a high-pressure gas cylinder 1, a pressure reducing valve 2, a water storage bottle 3, an air-water mixer 4, a spray gun 5 and an air breathing apparatus mask 6. The high-pressure gas cylinder 1 is connected to the pressure reducing valve 2 through a pipeline, and the output of the pressure reducing valve is connected to the intake pipe 44 of the gas-water mixer 4 one way, one way is connected to the water storage bottle 3, and the other way is connected to the air respirator through a pipeline mask6. The water outlet of the water storage bottle communicates with the water inlet pipe 45 of the air-water mixer 4 , and is connected with the spray gun 5 through the pipeline after being mixed by the air-water mixer 4 . The air-water mixer 4 is placed above the water storage bottle 3, and the spray gun 5 includes a housing 51, a trigger valve 53 placed in the housing,...

Embodiment 2

[0054] Portable low-resistance two-phase flow fine water mist fire extinguishing system with lower outlet structure such as Figure 6 As shown, the gas-water mixer 4 is placed under the water storage bottle 3. When using the fire extinguisher to work, the trigger 54 of the spray gun is pulled, and the trigger valve 53 is opened. In the valve 2, the high-pressure gas is decompressed by the pressure reducing valve 2 and divided into three paths, one path directly enters the gas-water mixer 4 through the pipeline, one path enters the water storage bottle 3 through the pipeline, and the other path is connected to the air respirator through the pipeline mask6. The water in the water storage bottle 3 is pressed into the air-water mixer 4 by the high-pressure gas; after passing through the air-water mixer, it enters the spray gun 5 through a hose and sprays out. The portable low-resistance two-phase flow fine water mist fire extinguishing system with the lower water outlet structure...

Embodiment 3

[0056] Portable low-resistance two-phase flow water mist fire extinguishing system with dual cylinders such as Figure 7 Shown, this system comprises a high-pressure cylinder 1 and an air respirator cylinder 1' that can be used by the respirator. After the two gas cylinders are connected by the pipeline, the output high-pressure gas is decompressed by the pressure reducing valve 2 and then divided into three paths, one path directly enters the gas-water mixer 4 through the pipeline, one path enters the water storage bottle 3 through the pipeline, and the other Connect the air respirator face mask 6 by pipeline. The water in the water storage bottle 3 is pressed into the air-water mixer 4 by the high-pressure gas; after passing through the air-water mixer, it enters the spray gun 5 through a hose and sprays out.

Abstract

The invention discloses a portable low-resistance two-phase flow water mist fire extinguishing system which belongs to the technical field of fire control and aims at solving the technical problem that the fire extinguishing device in the prior art can not realize high-range spray fire extinguishing at low power consumption. The portable low-resistance two-phase flow water mist fire extinguishingsystem comprises a water storage bottle (3) and an air / water mixer (4) communicated with the water storage bottle (3), wherein an air intake pipeline (44) of the air / water mixer (4) is communicated with an air supply, and an air / water outlet pipeline (41) is communicated with a spray gun (5). A gas / liquid channel of the fire extinguishing device is a low-resistance smooth flow channel. Compared with the like products, the fire extinguisher reduces the consumed power by 71% under the premise of the same range. The invention can be widely used for class A, class B and electrical fires.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to the field of a two-phase flow gas water mist fire extinguisher. Background technique [0002] In today's fire protection technology field, it is the most environmentally friendly to use water to extinguish fire at the fire scene. In order to further improve the fire extinguishing efficiency, water atomization is currently used, which can increase the fire extinguishing efficiency by a hundred times. This is because after the water is atomized, the diameter of the droplets is very small, and compared to the same volume of water, its surface area increases dramatically, thereby enhancing the efficiency of heat exchange and achieving a very good cooling effect. The fine water mist is quickly vaporized after absorbing heat, causing the volume to expand rapidly, usually reaching more than 1700 times, thereby reducing the oxygen concentration in the air, inhibiting ...
