Self-rescue flame-retardant device in case of underground coal mine fire

Abstract

The invention discloses a self-rescue flame-retardant device in case of underground coal mine fire. The self-rescue flame-retardant device includes a base, a pad block is fixedly connected to the base, an induced draft fan is fixedly connected to one end of the pad block, a corrugated hose is fixedly connected to one side wall of the induced draft fan, and a wind collecting hood is fixedly connected to one end of the corrugated hose. The self-rescue flame-retardant device draws air near a fire occurrence point into oxygen-enriched components with the help of the induced draft fan to separate and collect oxygen, through two times of separation and collection by two layers of oxygen-enriched membranes, most of the oxygen in the air is separated to prevent the spread of the fire and achieve the flame-retardant effect of the fire, oxygen-enriched air is collected into a high-pressure gas collecting cylinder through an air compressor, then the oxygen-enriched air can be used in conjunctionwith oxygen masks for underground operating personnel to breathe in a low oxygen environment, and the oxygen-enriched air can further be charged into oxygen cylinders for use by the underground operating personnel to rescue themselves and escape when the fire is out of control.

Description

technical field [0001] The invention relates to the field of mine fire self-rescue flame retardant technology, in particular to a self-rescue flame retardant device when an underground coal mine fire occurs. Background technique [0002] Coal mine fires refer to uncontrolled combustion that occurs in mines and threatens underground safety production and causes losses. Fires in mines often lead to casualties, equipment loss, mine shutdown, resource destruction, and even explosions of gas, coal dust or sulfide mine dust. [0003] When an underground coal mine fire occurs, in order to avoid greater losses, the underground workers need to try to put out the fire first, unless the fire develops out of control, the underground workers can take self-rescue measures, but it is difficult to effectively extinguish the fire in the coal mine, and it is very easy to recover In addition, the fire will consume a large amount of oxygen, thereby increasing the difficulty of self-rescue for ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: when a coal mine fire occurs, in order to avoid causing greater losses, the underground workers need to try to extinguish the fire first, unless the fire develops out of control, the underground workers can Take self-rescue measures, but it is difficult to effectively extinguish the fire in coal mines, and it is very easy to re-ignite, and the fire will consume a lot of oxygen, thus increasing the difficulty of self-rescue for underground workers
