Study on the Coal Mine Ventilation Air Methane Utilization Technologies Based on Flow-Reversal Oxidation Principle

Abstract

There is a huge amount of coal mine ventilation air methane emitted into the atmosphere directly each year in china, not only causes a lot of energy was wasted, but also do severe harm to the protection of the environment. The Utilization Technologies of coal mine ventilation air methane (VAM) are receiving more and more attention from people, Aiming at the domestic and international development status of VAM utilization, Thermal flow reversal reactor (TFRR) and catalytic flow reversal reactor (CFRR) are introduced, as two kind of flow-reversal oxidation technology which are the most popular and used widely. The economic and applicability about service life, total cost, space and performance of device are comparative analyzed, and illustrate the trends about the technology of flow-reversal oxidation of VAM from two aspects: to solve the problem of running stability well and improve its work efficiency reasonably. Finally, this paper outlines the future prospect for the development of this technology.
