摘　　要：我国近年来甲烷排放不断增加,各类甲烷排放源中,煤矿行业排放的瓦斯占比最高,若能有效利用空排瓦斯,不仅能降低污染,还能带来巨大的能源效益,其中低浓度瓦斯占比较高且利用难度大,对比分析低浓度瓦斯处理技术意义重大。本文分析了我国低浓度瓦斯利用现状,论述了回热氧化、提浓富集等低浓度瓦斯利用技术的原理与特性。逐一分析对比能耗、安全性、运行条件等,发现回热氧化技术优势较多。结果表明:采用RTO装置代替传统两室蓄热效果更好,由此针对关键参数设计正交实验方案,以供行业选用瓦斯处理技术参考。In recent years,China's methane emissions have been increasing,and among all kinds of methane emission sources,the coal mine industry accounts for the highest proportion of gas emissions.If air exhaust gas can be effectively used,it can not only reduce pollution but also bring huge energy benefits,among which low-concentration gas accounts for a relatively high proportion and is difficult to use.It is of great significance to compare and analyze low-concentration gas treatment technology.Firstly,this paper analyzes the present situation of low concentration gas utilization in China,and the principle and characteristics of low concentration gas utilization technologies such as reheating oxidation and enrichment are discussed.After analyzing and comparing energy consumption,safety and operating conditions,it is found that regenerative oxidation technology has many advantages.Finally,it is concluded that the rto device is better to replace the traditional two-chamber heat storage,and the orthogonal experiment scheme is designed according to the key parameters,so as to provide a reference for the industry to choose gas treatment technology.
