分子筛转轮处理青霉素发酵尾气应用技术研究

Study on application technology of molecular sieve rotor in treatment of penicillin fermentation exhaust gas

采用分子筛转轮空气过滤模块、除VOCs(挥发性有机物)模块(分子筛转轮浓缩模块)以及催化氧化模块,处理青霉素发酵尾气。结果表明,经分子筛转轮浓缩和催化氧化装置联合处理后的青霉素发酵尾气,其非甲烷总烃、挥发性有机物、臭气浓度等各项监测指标均大幅低于相关排放标准;同时,由于其通用性强、处理效率高、运行成本低、寿命长,已经成为大风量、低浓度含VOCs废气处理的首选方法。

The molecular sieve rotor including the modules of air filtration, VOCs (volatile organic compounds) removal (molecular sieve rotor concentration module) and catalytic oxidation was used to treat penicillin fermentation exhaust gas. The results show that the monitoring indicators such as non-methane hydrocarbons (NMHC), VOCs and odor concentration, etc. of penicillin fermentation exhaust gas treated by molecular sieve rotor and catalytic oxidation unit are significantly lower than the relevant emission standard. At the same time, due to its strong versatility, high processing efficiency, low operating cost and long life, it has become the preferred treatment method for high-volume, low-concentration VOCs-containing exhaust gas.
