Description

低高径比气体环流生物反应器
本实用新型涉及生物技术领域。
目前，生物技术飞速发展，采用气流搅拌，代替机械搅拌大势所趋，各种类型的内循环、外循环气升式反应器不断出现，但这些反应器普遍存在罐体的径高比大，使用操作不便的缺点。
本实用新型的目的是提供一种低高径比气体环流生物反应器，即：使气升式反应器的高径比与机械搅拌罐相近。
本实用新型的目的是这样实现的：
如图1所示，一股压缩空气通过喷嘴1高速喷出，推动醪液沿外循环管2向上提升，进入内循环管4；另一股压缩空气通过喷嘴3射出，将醪液沿内循环管4向下压缩，由内循环管下部喷出。由于导流板5的导向作用，使醪液在反应器内形成环流，从而实现气液多次混和，达到理想的传质、传热效果。采用以上原理和结构进行气体环流的生物反应罐，其罐体的径高比小。
本实用新型的具体结构由以下附图和实例给出。
图1为本实用新型结构示意图
现结合附图详细描述本实用新型的具体结构：
如图1所示，它由罐体6、喷嘴1、外循环管2、喷嘴3、内循环管4、导流板5组成，外循环管2设在罐体6的体外，内循环管4设在罐体6的体内。其特征在于：喷嘴1设在外循环管2的下部，压缩空气经该喷嘴向上喷气；喷嘴3设在内循环管4的上部，压缩空气经该喷嘴向下喷气，导流板5设在内循环管4的下方，从而推动醪液在反应器内形成环流。
本实用新型的优点是：1，采用本结构的生物反应器其罐体高径比在1∶2.6～3.0范围内，与机械搅拌罐相近。2，压缩空气与醪液多次混和，线路长，混合充分，传质效果好。3，醪液在循环过程中，有两次上下环流运动，搅拌效果理想。4，改换喷嘴可满足不同菌种发酵的工艺要求。5，应用本技术，可进行传统机械搅拌罐的技术改造。6，本实用新型结构简单，制造容易，工作可靠。本技术方案经反复试验证明，与同类机械搅拌罐相比，可节能30％，维修费可节省80％以上。
