【摘要】：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。
[Abstract]:In order to solve the technical problem of low methane oxidation rate in existing regenerative oxidation units, a five-bed exhaust gas heat storage and oxidation device was designed and its working principle was expounded.In the traditional heat storage and exothermic cycle, a purge purification process was added, the spent air residue was greatly reduced, and the oxidation rate of methane was increased to more than 98%.The design process of oxidation chamber, combustion chamber, air distribution chamber and preheating system, as well as the design scheme of the assembly structure of the unit are introduced.The technology will be industrial demonstration at Songzao No. 1 Mine in Chongqing, and the project is currently under construction.After the industrial demonstration system is put into operation, it can produce 64800 tons of superheated steam every year and reduce CO2 equivalent of 107000 t, which has good energy saving and emission reduction benefit.
