一种全流程连续化气助磁分离系统 技术领域
本发明涉及磁分离处理设备技术领域，尤其涉及一种全流程连续化气助磁分离系统。
背景技术
磁性载体分离技术是通过偶联在磁性载体表面的亲和配基、疏水基团、离子交换基团等对目标组分进行吸附，然后利用合适的磁分离装置将负载了目标物的磁性载体分离出来，并经过清洗、洗脱来直接快速的分离目标物的新型分离技术。磁性载体分离技术从20世纪70年代起开始发展起来，并获得了很大发展。由于该技术具有分离快速简单，选择性高，分离迅速和可直接适用于复杂体系的分离等优点，因此被提出和广泛研究应用于免疫检测、细胞标记和分离、核酸分离、蛋白质纯化、废水处理、天然产物分离等领域。
但是，该技术用于分离领域时，由于分离对象大多数时候是稀溶液甚至极稀溶液，适度增大处理规模就面临着巨大挑战。现有的磁分离装置要么处理规模太小无法适应要求，要么放大后装置内空间磁场强度及梯度不够，导致空间内流动的弱磁性颗粒和超细磁性颗粒，尤其是纳米磁性颗粒，所受磁力太弱而不能被快速有效捕集。如何有效的处理大量含磁颗粒的稀溶液是磁性载体分离技术应用中的一个突出问题。

其中，位于首端的萃取塔2的混合液入口和混合液出口连接，末端的萃取塔2的萃余液出口连接萃余液储罐12。
或者包括多个萃取塔2，每个萃取塔2的混合液入口分别与混合液出口连接，每个萃取塔2的萃余液出口连接萃余液储罐12。
上述的两种形式分别是多个萃取塔2串联连接和并联连接的形式，其中，萃取塔2串联连接时，为多级磁分离，可使萃余液中磁颗粒物分离的更充分；而采用并联连接时，可同时使用多个萃取塔2，其磁分离效率更高。
同理，解吸塔3也可以为串联连接或并联连接，即包括多个解吸塔3，多个解吸塔3之间通过磁颗粒入口和产品出口串联连接；
其中，位于首端的解吸塔3的磁颗粒入口与混合物储罐10连接，末端的解吸塔3的产品出口连接产品储罐13。
或者，包括多个解吸塔3，每个解吸塔3的磁颗粒入口分别与混合物储罐10连接，每个解吸塔3的产品出口与产品储罐13连接。
串联连接的解吸塔3，对于磁颗粒回收更加充分，降低磁颗粒的循环损失；而并联连接的解吸塔3可提高磁颗粒的回收效率。
料液进口4、磁颗粒进口5及搅拌装置6均设于吸附罐1的罐盖上，吸附罐1的罐盖连接有升降组件。
通过设置升降组件可将吸附罐1进行升降操作，便于后期对装置内部进行维护和检修。其中，升降组件为伸缩气缸，液压缸，电葫芦等等均可。
优选的，吸附罐1与萃取塔2之间、萃取塔2与解吸塔3之间以及冲洗装置与刮板9之间均设有蠕动泵14。其中，蠕动泵14的流量的调节范围为3～6800mL/min。
本实施例中还包括控制装置，控制装置包括控制器，控制器与搅拌装置6、磁辊8、升降组件和蠕动泵14连接，控制器上设有控制按钮。控制装置设置在该系统的下部，便于操作，控制装置上设有相应的控制按钮，便于操作者的统一操控。
本实施例中还包括供气管路，供气管路分别与萃取塔2和解吸塔3的气体入口连接，萃取塔2和解吸塔3的气体入口处设有气体流量计15。
萃取塔2和解吸塔3通过供气管路进行统一的供气操作，其中，在气体入口处设置相应的气体流量计15，气体流量计15的的量程设置为6～60L/h。
磁辊8包括磁弧形区16，磁弧形区16的弧度为240°。使磁辊8的磁弧形区16域表面对磁颗粒有着较均匀的捕集力，在磁路系统设计中，通过一定量小 型的铷铁硼稀土永磁铁沿筒表面以一定间距排列成环形，使其能在套筒表面产生均匀磁场强度。
其中，该全流程连续化气助磁分离系统，所用的混合物储罐10、磁颗粒储罐11、萃余液储罐12、产品储罐13以及冲洗液储罐17均为不锈钢材质，一般情况下将其形状设置为长方体形。同时，可设置多个备用储罐，用于配置和储存洗涤清液和解吸液等。
具体使用时，将磁性载体(即磁颗粒)与含有目标分离物的溶液在吸附罐1内进行混合，通过搅拌装置6充分搅拌，加速磁颗粒对目标物的萃取过程和促进磁颗粒的充分悬浮，然后泵入萃取塔2(以两个萃取塔2为例，可以只用一个、可以同时用、也可以交替用或串联使用)，磁颗粒在气浮柱7的协助下被磁辊8充分捕获，从冲洗液储罐17中泵出冲洗液将磁辊8上的磁颗粒洗涤下来，并收集进入混合物储罐10，萃余液收集进入萃余液储罐12，混合物储罐10内的悬浮液泵入解吸塔3，解吸塔3内有解吸液，目标物从磁颗粒上解吸下来，进入产品储罐13，解吸后的磁颗粒被磁辊8捕获，通过冲洗液洗涤下来，进入磁颗粒储罐11，磁颗粒可回流到吸附塔内进行循环利用，并形成连续闭路循环。
以上结合具体实施例描述了本发明的技术原理。这些描述只是为了解释本发明的原理，而不能以任何方式解释为对本发明保护范围的限制。基于此处的解释，本领域的技术人员不需要付出创造性的劳动即可联想到本发明的其它具体实施方式，这些方式都将落入本发明的保护范围之内。
