    • A mixing system is disclosed comprising at least one extensional flow mixer comprising: a generally open and hollow body having a contoured outer surface and having: a single entrance port and a single exit port; a means for compressing a bulk stream flowing through the generally open and hollow body in a direction of flow and at least one injected additive stream introduced at the single entrance port in the direction of flow; and a means for broadening the bulk stream and the at least one injected additive stream such that an interfacial area between the bulk stream and the at least one injected additive stream is increased as the bulk stream and the at least one injected additive stream flow through the generally open and hollow body in the direction of flow to promote mixing of the bulk stream and the at least one injected additive stream, a flow conductor having an axis and having a generally open and hollow flow mixer body secured therein; and a primary additive stream injector positioned at the entrance port of the generally open and hollow flow mixer body, wherein the primary additive stream injector injects an additive stream into the interior of the flow mixer in the direction of flow when the bulk stream is flowing through the generally open and hollow flow mixer body to allow compression and broadening of the bulk stream and the additive stream together to facilitate mixing of the bulk stream and the primary additive stream at an exit of the extensional flow mixer, wherein the extensional flow mixer is followed by at least one of helical static mixing elements that is at least one half flow conductor diameter downstream of the exit of the extensional flow mixer.
    • 公开了一种混合系统,该混合系统包括至少一个延伸流动混合器,包括:具有轮廓外表面的大致敞开且中空的主体,具有:单个入口和单个出口; 用于沿流动方向压缩流过大体上敞开的中空体的主体流和沿着流动方向在单个入口处引入的至少一个注入的添加剂流的装置; 以及用于使本体流和至少一个注入的添加剂流扩展的手段,使得当本体流和至少一个注入的添加剂流流过该流体流时,本体流和至少一个注入的添加剂流之间的界面面积增加 通常在流动方向上开放和中空的体,以促进本体流和至少一个注入的添加剂流的混合,具有轴线并具有固定在其中的大体上敞开且中空的流动混合器主体的流动导体; 以及位于大体上敞开的中空流动混合器主体的入口处的主要添加剂流注入器,其中当主体流流过时,主要添加剂流注入器将流动混合器的内部流向流动方向的内部注入流动混合器的内部 通常是开放和中空的流动混合器主体,以允许将本体流和添加剂流压缩和扩展在一起,以便于在延伸流动混合器的出口处混合本体流和初级添加剂流,其中遵循该拉伸流动混合器 通过至少一个螺旋静态混合元件,其是在延伸流动混合器的出口下游的至少一个半流动导体直径。
