8万吨每年赖氨酸生产装置二级种子罐工艺跟设备设计.docVIP

摘 要 赖氨酸的发酵过程主要包括斜面种子活化、种子罐扩大培养和发酵罐发酵。种子罐扩大培养在赖氨酸发酵过程中占有重要的地位。本设计依照GB150和《化工容器与设备简明设计手册》等文献，对种子罐进行设计。先行设计种子罐筒体，封头的尺寸与厚度并进行液压试验机强度校核。由于反应介质有一定的腐蚀性，所以采用不锈钢材料。然后设计设备的冷却装置。由于发酵过程中对温度稳定的要求高，所以采取外盘管和内蛇管联合使用的冷却装置。最后设计设备的搅拌传动装置和接管附件。因为发酵过程要求严格无菌操作，对设备密封性能要求高，本设计中采用机械密封。 关键词：赖氨酸，种子罐，内蛇管，无菌操作 Abstract Lysine fermentation process mainly includes inclined surface activation of seed, seed tank and enlarged culture fermentation tank fermentation. Seed tank to expand training in lysine fermentation process plays an important role in. In accordance with the design of GB150 and chemical containers and equipment concise design handbook literature, the seed tank design. First design seed tank barrel body, head size and thickness and strength check of hydraulic test machine. As the reaction medium have certain corrosive, so the use of stainless steel materials. Then the design of equipment cooling device. As a result of the fermentation process for the high temperature stability requirements, so taken outside the coil and the inner coil pipe joint use of cooling device. The final design equipment stirring transmission device and attachment of nozzle. Because the fermentation process requires strict aseptic operation, the device sealing performance requirements, the design of the use of mechanical seal.
