为解决现有蓄热氧化装置存在的甲烷氧化率较低技术难题,设计了五床式乏风瓦斯蓄热氧化装置,阐述了装置的工作原理。该装置在传统的蓄热、放热循环中增加了1个吹扫净化过程,大幅减少了装置中的乏风残留量,将甲烷氧化率提高至98%以上。介绍了氧化室、燃烧室、气流分配室及预热系统等部件的设计过程,以及装置的总装结构设计方案。该项技术将在重庆松藻打通一矿进行工业性示范,目前项目正处于建设阶段。该套工业性示范系统投入运行后,每年可生产过热蒸汽6.48万t,减排CO2当量10.7万t,具有良好的节能减排效益。

In order to solve technical problem of low methane oxidization rate existed inthe available thermal accumulation oxidized device,a five bed type structure m ode of mine ventilation air methane thermal accumulation oxidized device was designed and the working principle of the device was stated.There was a blowing and purific ation process added in the traditional thermal accumulation and thermal releasing circulation of the device,the mine ventilation air methane residual volume in the device W ould be highly reduced and the methane oxidization rate would be improved over 98%. The paper introduced the design process of the oxidation chamber,combustion cham ber,airflow distribution chamber,preheating system and other parts as well as the general structure design plan of the device. The technology would have an industrial dem 0 in Chongqing Songzao Datong No.1 mine and the project is in a construction stage . After the completed industrial demo system put in operation,a superheated steam pro duction would be 64 800 t annually,the emission reduction of CO2 equivalent would107 000 t and an excellent energy saving and emission reduction benefits would be obta ined.
