Ultrafine dry powder cold gas sol fire extinguishing device

Abstract

The invention discloses an ultrafine dry powder cold gas sol fire extinguishing device which comprises an ultrafine dry powder fire-extinguishing agent storing container, an ultrafine dry powder spray device and a high-pressure gas drive device, wherein the ultrafine dry powder fire-extinguishing agent storing container is provided with a gas inlet and a powder spray opening; the ultrafine dry powder spray device is sealed and connected with the powder spray opening; the high-pressure gas drive device is sealed and connected with the gas inlet; the ultrafine dry powder spray device comprises a powder spray pipe, an ultrafine dry powder outlet nozzle, a dry powder spray sealing membrane which is arranged in the powder spray pipe and a fan which is arranged in the front or the back of the ultrafine dry powder outlet nozzle; and the high-pressure gas drive device comprises a gas storing bottle which is connected with the gas inlet through a gas inlet pipeline, a gas circuit control valve and an inflating and connecting pipe which is inserted into the storing container and is provided with a gas inlet nozzle. The invention has reasonable design, simple structure, low processing and manufacture cost, simple and convenient use and operation, convenient distribution, high fire extinguishing speed, high fire extinguishing efficiency, environmental protection and no pollution, and simultaneously can be effectively suitable for areas needing fire extinguishment, such as wells, roads, cable chutes, tunnels, subways, and the like.

Description

technical field [0001] The invention relates to a coal mine safety production emergency rescue equipment, in particular to an ultra-fine dry powder cold aerosol fire extinguishing device suitable for fire extinguishing processes in underground mines, roadways, cable trenches, tunnels, tunnels, etc., and capable of quickly extinguishing fires. Background technique [0002] For emergency fire extinguishing of underground mines, roadways, cable trenches, tunnels, tunnels, etc., it is mainly divided into fire extinguishing of gobs and scrapped roadways and underground mines, roadways, cable trenches, tunnels, and tunnels used in roadway fire areas or where gas and coal dust occur There are two types of fire extinguishing after an explosion accident. At present, the fire extinguishing methods used mainly include grouting and sand injection, water injection, technical spraying of chemical inhibitors, foam fire extinguishing, equal pressure fire extinguishing, plugging fire extingu...

AI Technical Summary

Problems solved by technology

The above-mentioned fire extinguishing methods have their own advantages and disadvantages. Some fire extinguishing methods take a long time to extinguish the fire. For example, the grouting sand injection method takes a week or even several weeks. In addition, the gel fire extinguishing, nitrogen, carbon dioxide and other inert gas fire extinguishing methods usually need several days. ; Some fire extinguishing methods have low efficiency, such as water injection fire extinguishing technology, spraying chemical inhibitor fire extinguishing method, etc.
