Embodiment Construction

[0032] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but 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 making creative efforts belong to the protection scope of the present invention.

[0033] This embodiment provides a coal mine gas regenerative oxidation method. The coal mine gas whose concentration is lower than 30% is adjusted to an ultra-low concentration of 1.2% to 3% and sent to the regenerative oxidation device, and the regenerative oxidation device is adjusted according to the following formula The flow rate of gas can realize the regenerative oxidation of ultra-low concentration gas,

[0034] V ≤ 0.1466e 35.7D e 0.00162T

[0035] Among them, V is the superficial flow velocity of ...

Abstract

The invention provides a coal mine gas regenerative oxidation method, and belongs to the technical field of coal mine gas utilization. The coal mine gas with the concentration lower than 30% is adjusted to 1.2%-3%, the coal mine gas is fed into a regenerative oxidation device, and regenerative oxidation of ultra-low-concentration gas is achieved by adjusting the flow rate of the gas in the regenerative oxidation device. The method has the advantages of high safety, high reliability and high economical efficiency.

Description

technical field [0001] The invention belongs to the technical field of coal mine gas utilization, and specifically discloses a coal mine gas regenerative oxidation method. Background technique [0002] According to the "Coal Mine Safety Regulations": "When gas is used, the gas concentration shall not be lower than 30%", the reason is that gas with a concentration lower than 30% contains methane concentration in the range of 5% to 16%. Explosive hazardous gases are generally forbidden to be used for safety reasons, but direct discharge not only wastes resources but also pollutes the environment. With the development of science and technology, the utilization of gas with a concentration of less than 30% has also undergone new developments. At present, the utilization of low-concentration and ultra-low-concentration gas mainly includes the following four ways. [0003] 1. Gas power generation: low-concentration gas power generation in coal mines and transmission safety assuran...
