Differential pressure mine automatic fire extinguisher based on novel extinguishant

Abstract

The invention discloses a differential pressure type mine automatic fire extinguisher based on a novel extinguishant. The differential pressure type mine automatic fire extinguisher comprises a high-pressure fire extinguisher, a running piping is connected to the outer surface of one end of the high-pressure fire extinguisher, an expansion valve is arranged on the inner side of the running piping,a communicating vessel is arranged on the other end of the running piping, a plurality of groups of atomization spraying heads are arranged on one side of the communicating vessel, and a fire sourcedetector is arranged on the outer surface of the lower end of the running piping. When a fire happens, gas in an expansion air pressure package in the fire source detector expands, the high-pressure gas is transported to the expansion valve, the expansion valve is pushed to be opened, the high-pressure extinguishant is transported to the atomization spraying heads, refining treatment is conductedon the extinguishant through the atomization spraying heads, the schistose extinguishant is sprayed out and evenly sprayed in a large range towards all around through the action of a cone table, thusthe fire source is quickly put out, when the automatic control system failure occurs or manual operation is needed, a manual trigger button is triggered manually, the expansion valve is controlled tobe opened, and manual fire extinguishing is conducted.

Description

technical field [0001] The invention relates to the field of automatic fire extinguishers, in particular to a differential pressure mine automatic fire extinguisher based on a novel fire extinguishing agent. Background technique [0002] Nowadays, my country's mining industry is becoming more and more developed, and the requirements for mine operations are getting higher and higher, and the control of safety requirements for mine operations is gradually improving. When working underground, especially in the coal mining industry, fires must be avoided. For this reason, most of the mines are equipped with special fire extinguishers everywhere for fire extinguishing. [0003] At present, the existing fire extinguishers can only be used to extinguish the fire manually. When a fire occurs, due to the chaotic scene, the delay of manual fire extinguishing is relatively high, which will easily cause the fire to be more serious, and even cause the lives of workers to be endangered.

[0003] At present, the existing fire extinguishers can only be used to extinguish the fire manually. When a fire occurs, due to the chaotic scene, the delay of manual fire extinguishing is relatively high, which will easily cause the fire to be more serious, and even cause the lives of workers to be endangered. Moreover, the existing fire extinguishers can only be used for one type Combustion type fire extinguishing is counterproductive when encountering some special fire sources. Therefore, an automatic fire extinguishing system that can deal with a variety of fire situations quickly and without electric energy assistance has become the demand for mine operations today. Therefore, we propose this Differential pressure mine automatic fire extinguisher based on new fire extinguishing agent
