Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Before entering the scene of fire, utilize the braces 9 to carry the device on one's back, and straps are tied around the waist simultaneously. After entering the fire scene, put on the breathing mask 8, turn on the gas cylinder switch 2, the compressed air is decompressed by the pressure reducing valve 3, and provides air for the fire fighters, and the air pressure is detected by the pressure gauge 7 at the same time. Open the gas cylinder switch 23, after the gas passes through the gas distribution valve 22, the gas decompressed by the gas decompression valve 20 provides a pressure of 0.8-0.9 MPa for the water tank, and the gas pressure after decompression by the gas decompression valve 20 is 0.9 -1.0Mpa. After finding the fire source, hold the fine water mist spray gun 19, pull the trigger of the spray gun to open the gas and liquid two-phase medium f...

Abstract

The invention discloses a backpack effervescent atomization water mist fire extinguishing device, which belongs to the field of fire control extinguishing. According to the technical scheme adopted in the invention, the device consists of two compressed air bottles, a water tank and a specially-designed effervescent atomization water mist spray gun, wherein the assemblies are fixedly arranged on a back plate, and are backed through belts. Air in one of the two compressed air bottles is used by an air respirator through a hose, and air in the other compressed air bottle is used by a water mist generating system. The device is formed by integrating a water mist fire extinguishing device and the air respirator, so that the life safety of fire extinguishing personnel can be ensured during rapid and efficient fire extinguishing. The device can be used for effectively extinguishing type A, B and E fire disasters, and is particularly effective to initial fire disasters of types A, B and E and small fire disasters.

Description

technical field [0001] The invention relates to a fire-fighting fire extinguishing device, in particular to a backpack-type bubble atomization fine water mist fire extinguishing device. Background technique [0002] Water mist technology has the characteristics of no environmental pollution, low water consumption, and little damage to protected objects. As the most ideal substitute for halon fire extinguishing agents, it has received extensive attention and application in recent years. According to the pressure, the water mist system can be divided into: high pressure water mist system (P≥3.45MPa), medium pressure water mist system (3.45MPa>P≥1.21MPa), low pressure water mist system (P<1.21MPa); According to different atomizing media, it can be divided into single-fluid fine water mist system and double-fluid fine water mist system. High-pressure water mist is mainly single-fluid, and its atomization principle is basically pressure atomization and swirl atomization. T...
