    摘要： The invention provides a mixing system comprising the following: A) 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; B) a flow conductor having an axis and having a generally open and hollow flow mixer body secured therein; and C) 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 for compression and broadening of the bulk stream and the additive stream together within the extensional flow mixer, to facilitate mixing of the bulk stream and the primary additive stream at an exit of the extensional flow mixer; and wherein the extensional flow mixer is followed by D) at least one helical static mixing element that is at least one half "flow conductor diameter (D
    1 )" downstream of the exit of the extensional flow mixer.

    摘要翻译： 本发明提供了一种混合系统，该混合系统包括：A）至少一个拉伸流混合器，其包括：具有波状外表面并且具有：单个入口端口和单个出口端口的大体上敞开的中空主体; 用于在流动方向上压缩流过大体上开口且中空的主体的散装物流的装置，以及沿流动方向在单个入口处引入的至少一个注入的添加剂流; 以及用于加宽本体流和至少一种注入添加剂流的装置，使得本体流和至少一种注入添加剂流之间的界面面积随着本体流和至少一种注入添加剂流流过 在流动方向上的大体上敞开且中空的本体以促进本体流和所述至少一种注入的添加剂流的混合; B）具有轴线并具有固定在其中的大致开口且中空的流动混合器本体的流动导体; 以及C）定位在大致开口的中空流动式混合器本体的入口处的主添加剂流注射器，其中当主流添加剂流注入时，主添加剂流注射器沿流动方向将添加剂流注入流动混合器的内部， 流过大致开放的中空流动混合器本体，以允许在伸长流混合器内一起压缩和扩大本体流和添加剂流，以促进本体流和主添加剂流在混合器出口处的混合 拉伸流动混合器; 并且其中所述拉伸流混合器之后是D）至少一个螺旋静态混合元件，所述螺旋静态混合元件是所述拉伸流混合器的出口下游的至少一半“流动导体直径（D 1）”。
