摘　　要：为解决乏风瓦斯催化氧化利用监控设计中存在的"信息孤岛"与"重复建设"问题,以提高安全监控系统的可靠性与稳定性为目的,设计了一套乏风瓦斯催化氧化综合监控系统,其综合了监控瓦斯掺混系统、逆流回热系统、离心压气机系统、催化燃烧室、发电机,实现对乏风瓦斯催化氧化过程的远程监控。分析了乏风瓦斯催化燃烧燃气轮机发电工艺流程、监控系统控制原理,以及系统控制流程,对系统安全防护硬件、软件进行了设计,工业性试验表明,该综合监控系统具有良好的稳定性与可靠性。A comprehensive monitoring system of ventilation air methane catalytic oxidation was designed for low-concentration methane utilization in order to solve the problems of the "information island" and repeated construction" in the design of the monitoring system of the ventilation air methane catalytic oxidation application and improve the reliability and stability of the system. This monitoring system of ventilation air methane catalytic oxidation integrated the methane mixing system, the countercurrent back heating system, the centrifugal compressing system, the catalytic combustion chamber and the electric generator, thus realized the remote monitoring of the ventilation air methane catalytic oxidation process. Analysis was carried out on technological process of the electric generation of the steam turbo-generator by ventilation air methane catalytic combustion and the control principle and process of the monitoring system, and design was made on the safety protection hardware and software of the system. The industrial tests showed that this comprehensive monitoring system had good stability and reliability.
