METHOD AND ABATEMENT DEVICE TO DESTROY LOW-CONCENTRATION COALMINE METHANE

摘要

Abstract 593363 Disclosed is a method and apparatus for destroying coal mine low concentration methane gas and an apparatus thereof. The method consists of the following steps: (A) electrifying an oxidizing bed (39), and starting and heating the oxidizing bed to be at least 800?; (B) inputting coal mine low concentration methane gas into the oxidizing bed (39), carrying out the rapid reaction of methane and oxygen, and releasing heat; (C) storage (11) for storing the heat; (D) discharging clean waste gas out of the oxidizing bed (39) after the reaction; (E) switching the direction, and inputting the coal mine low concentration methane gas into the oxidizing bed (39) again so as to carry out a rapid oxidization reaction and release heat; and (F) storing and outputting redundant reaction heat, and repeating the steps (B)(C)(D)(E)(F). The apparatus consists of a switch valve mechanism (47), the oxidizing bed (39), a recovery valve mechanism, a gas inlet system and a process detection and control system. The switch valve mechanism (47) and the oxidizing bed (39) are assembled together and are integrated with the recovery mechanism (37) and the gas inlet system into a whole.
