摘要
煤矿瓦斯综合利用是煤矿甲烷减排的主要途径。由煤矿抽采泵站抽采出的瓦斯经过瓦斯掺混装置与空气(或乏风)进行均匀混配,混配后的浓度小于1.2%,经旋转阀式蓄热氧化装置进行无焰氧化,氧化后产生的热通过余热锅炉系统、发电系统,进行煤矿瓦斯综合利用。通过旋转阀式蓄热氧化工艺对煤矿瓦斯甲烷浓度不超过8%加以利用,助力煤矿实现温室气体减排。
The comprehensive utilization of coal mine gas is the main way to reduce methane emissions in coal mines. The gas extracted by the coal mine pumping station is evenly mixed with air(or ventilation air methane) through the gas distribution system, resulting in a mixture with a methane concentration of less than 1.2%. This mixture undergoes flameless oxidation in a rotary valve regenerative oxidation device, and the heat generated from the oxidation is utilized in the comprehensive utilization of coal mine methane through systems such as the waste heat boiler and power generation system. The methane concentration of coal mine methane through the rotary valve regenerative oxidation process is not more than 8%. This technology helps coal mines reduce greenhouse gas emissions.
