Description

一种可非等动量受限射流撞击混合的方法 技术领域
本发明涉及受限射流撞击式混合方法，特别涉及一种可非等动量受限射流撞击混合的方法。
背景技术
受限撞击射流(confined impinging jets，CIJ)混合被用于瞬时纳米制备(flash nanoformation，FNF)技术之中，可快速、高效、节能、连续制备纳米悬浮液(瞬时纳米析出法，flash nanoprecipitation，FNP；专利号：US20040091546A1)或纳米乳液(瞬时纳米乳化法，flash nanoemulsification，FNE；专利号：ZL2015105158105)。通过瞬时混合两股及以上流体，在密闭且微小体积的混合腔体内，溶质的过饱和度瞬时提高，疏水分子继而团聚形成纳米固体颗粒或纳米液滴。常规CIJ-D方法采用将各股流体注射入混合器入口的方式，在混合腔体内发生撞击的两股流体需要接近等动量混合，否则大动量的一股流体将把小动量的一股流体顶出射流入口，大大影响其混合效果。接近等动量的混合决定了从混合器出口流出的混合液中两流体组分接近1∶1，相当部分的纳米颗粒往往尚未能析出形成，混合液流出混合器后往往需要进行二次稀释混合，各批次颗粒粒径大小受到二次稀释的影响而较难控制，平均粒径会增大、分布会变宽。另外，在常规CIJ-D方法中，混合器各入口的流量需要独立且同步控制，导致设备和操作不够简单和方便。
发明内容
发明目的：本发明目的是提供一种可非等动量受限射流撞击混合的方法。
技术方案：本发明提供一种可非等动量受限射流撞击混合的方法，将混合器的各入口与各待混合流体分别使用入口导管连接；将混合器的出口与抽吸装置的入口使用出口导管连接；启动抽吸装置，各待混合流体先后通过入口导管及混合器入口进入混合器，在混合器腔体内混合后，混合液被从混合器的出口吸出，通过出口导管和抽吸装置入口，从抽吸装置出口流出。
进一步地，所述混合器包括至少两个入口。
进一步地，所述混合器腔体为密闭空间，且体积不大于100μL。
混合器腔体为密闭空间，以确保混合器不漏气，在混合器出口处抽吸时，入口处流体能被稳定吸入；上述方法中混合器腔体体积不大于100μL，以确保混合为体积受限混合。
进一步地，所述入口导管的直径不小于0.5mm。
连接混合器入口与待混合流体的导管直径需要不小于0.5mm，以确保导管直径不小于混合器腔体内喷嘴口的直径0.5mm。
进一步地，所述混合器腔体内液体处于湍流混合状态，出口处的雷诺数不小于1000。
雷诺数不小于1000，以确保腔体内流体处于湍流混合状态，各流体在腔体内瞬时混合均匀。
进一步地，所述各待混合流体组分之间能互相溶解。
各待混合流体混合后能相互溶解形成连续的一相。
进一步地，所述被从混合器腔体内吸出的液体是溶液或悬浮液或乳液。
进一步地，所述各入口导管上设置调节阀门。
进一步地，所述各入口导管等效长度不全等、各入口导管等效内径不全等、各入口调节阀门开度不全等或各入口导管内壁粗糙度不全等，以上任一种或几种情况的组合均可进行非等动量受限射流撞击混合。
上述方法中根据Hagen-Poiseuille公式，流体在管道里的压降与管道的等效直径的4次方成反比，与长度成线性正比，因此各导管之间具有的直径越大以及长度越小，所对应混合腔体喷嘴口的射流对撞流体之间动量会越大。
另外，入口导管上设置调节阀打开程度越大、各入口导管内表面粗糙程度越小，流体在导管内的压降越小，该入口导管所对应混合腔体喷嘴口的这一射流流体动量会越大。
上述方法中各股流体在混合器腔体内瞬时混合的同时，可以发生分子间化学反应或分子间聚集的物理反应，形成分子水平分散的溶液或固体颗粒的悬浮液或液滴颗粒的乳液，继而从混合器出口流出。
本发明所公开的方法采用从混合器出口抽吸流体的方式，同时通过调节流体在混合器各入口管路中的压降(如调节各管路等效直径、等效长度、调节阀、管壁粗糙程度等)，实现混合腔体内射流撞击流体间的大动量比，以及流量比的可调，而无需使用二次稀释。同时，该方法控制出口流量来代替同步控制各入口流量，使操作和设备大大简化。本发明将该方法命名为非等动量受限撞击射流(imbalanced momentum confined impinging jets，IMCIJ)混合，相应的混合器被称为IMCIJ混合器。
有益效果：本发明的方法可实现非等动量受限射流撞击的混合，流量比的可调，而无需使用二次稀释，操作简便。由本发明方法制备的纳米颗粒粒径更小，分布更窄。
