Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] The present invention provides a CO 2 The method of mixing gas and solid adsorbent to extinguish fire and seal it up is used in coal mine goaf fire extinguishing. First, solid adsorbent is spread in the goaf. In this embodiment, the solid adsorbent is calcium oxide powder. Comprehensive consideration Price and effect, calcium oxide powder is preferably industrial solid powder with a purity of 90%, and in other embodiments, the solid adsorbent c...

Abstract

a CO 2 A method for mixing and storing gas and solid sorbent to extinguish fire and its test system, including spreading solid sorbent in the goaf of coal mine; 2 gas, CO 2 The gas reacts with the solid adsorbent at high temperature to form a solid that is sealed in the goaf to prevent CO 2 The gas leaks into the atmosphere, preventing it from becoming a source of greenhouse gas emissions, which is conducive to environmental protection.

Description

technical field [0001] The invention belongs to the field of coal mine safety fire prevention, in particular to a CO 2 A method for mixing gas and solid adsorbent to extinguish and store fire and its test system. Background technique [0002] In recent years, mine fires have become more and more serious, and inert gas has been widely used in the fire prevention and extinguishing of goafs in underground coal mines. In inert gas fire extinguishing, CO 2 With its advantages of low price, short fire extinguishing time and good effect, gas is more and more used in the fire prevention and extinguishing of gobs in underground coal mines. But due to CO 2 The widespread use of gas in underground gob fire extinguishing also brings about a problem, that is, the CO injected into gob fire extinguishing 2 The gas will enter the air return lane of the working face through the air leakage flow in the goaf, and finally enter the atmosphere, becoming the source of greenhouse gas emissions...
