为防治煤矿井下火灾,特制成移动式制氮设备二套,其性能为:产氮量500m~3/h,氮纯度>98%.装置的工作原理为碳分子筛变压吸附流程.设备分装于两个集装箱,便于救灾时移往井口,置于地面通过管路使用.文章简述了对设备全机性能测试情况,并通过实用时出现的状况,以及运行期的经济分析,表明设备符合于煤矿防灭火所需.
For the prevention and control of coal mine fires, specially made of mobile nitrogen equipment, two sets of its performance: production of nitrogen 500m ~ 3 / h, nitrogen purity> 98%. The working principle of the device for carbon molecular sieve pressure swing adsorption process. Installed in two containers to facilitate the relief to the wellhead, placed on the ground through the pipeline to use.This article outlines the whole equipment performance test equipment, and through the practical situation, as well as economic analysis of the operation period, indicating that equipment In line with the needs of coal mine fire fighting.
