Coal mine inert gas foam extinguishing system

Abstract

The invention inlets inert gas and foam mixed liquor to the inert foam generator, the inert foam generator is a sealed container. The inert gas and the foam mixed liquor is insulated with the air in the inert foam generator, and the produced inert foam leads to the fire district, to stifle and put out source of fire by double-isolated function ( inert gas isolation, foam isolation). The water is input into a proportioner by a transmission pipe from a pressure water source, the foam stock solution is input to the proportioner from a foam liquor storage tank, the water and the foam stock solution are mixed by the proportioner to form the foam mixed liquor, then the foam mixed liquor is input to the inert foam generator; the inert gas is input the inert foam generator by the inert gas transmission pipe, the inert gas and the foam mixed liquor are isolated with the are in the inert generator, the produced inert gas foam leads to the fire district to put out fire, the inert gas is composed of the inert gas generator and an inert gas bottle.

Description

technical field [0001] The invention belongs to the technical field of fire protection and relates to a coal mine inert gas foam fire extinguishing system. Background technique [0002] Underground fires in coal mines are a major hidden danger that plagues coal mine safety, and more than 90% of these fires are caused by coal spontaneous combustion. Coal spontaneous combustion will form surface fires and deep fires. In addition to using plugging and grouting fire extinguishing methods, there is no international solution. Good approach to this problem. Contents of the invention [0003] The present invention passes the inert gas and the foam mixture into the inert bubble generator, the inert bubble generator is a sealed container, the inert gas and the foam mixture are isolated from the air in the inert bubble generator, and the inert gas foam is generated In the fire area, use double isolation (inert gas isolation, foam isolation) to suffocate and extinguish the fire sourc...
