摘　　要：介绍矿井气的组成和水环式真空泵的工作原理,分析矿井气中水分对系统的影响。比较3种脱水技术方案:低温脱水和吸附脱水双重脱水工艺、无热再生吸附脱水工艺、加热再生吸附脱水工艺。工程实例采用低温脱水和吸附脱水双重脱水工艺,实际运行效果良好。The mine gas composition and work- ing principle of water ring vacuum pump are introduced, and the influence of moisture in mine gas on the system is analyzed. Three kinds of dehydration technology solutions including low temperature dehydration and adsorption dual dehydration process, no heat regenerative adsorption dehydration process and heating regenerative adsorption dehydration process are compared. An engineering example adopts low temperature dehydration and adsorption dual dehydration process, and the actual running effect is good.
