优选实施例的详细描述
参看图1,显示了一种用于处理来自发动机或其它产生排气的装置11的排气流(由箭头A示意性地显示)的系统10。系统10包括流径12、一个或多个添加剂喷射器14、混合器16,以及成选择性催化还原(SCR)催化器18的形式的后处理元件或区。可以以任何适当的形式提供流径12,并且典型地,将以排气管道或排气管以及/或者用于催化器18的壳体的形式提供流径12,并且流径12可与其它排气处理结构(诸如,例如消声器或特定的过滤器)结合或集成。添加剂喷射器(一个或多个)14也可为任何适当的形式,其中许多是已知的,并且在所示实施例中,添加剂喷射器14优选在混合器16和催化器18的上游将试剂溶液(由箭头B示意性地显示,典型地是尿素溶液)喷射到柴油机排气流A中。
参看图2-5,混合器16包括盘形壁结构或鼻部20,以及从壁结构20沿径向向外延伸到环形凸缘24的锥形壁结构22,其中所有的特征20、22、24均关于中心轴线25同心,并且凸缘24大小设置成以便接合流径12的圆柱形内壁表面。第一组(在所示的实施例中为十个)混合器叶片28承载在壁结构20上,而第二组(在所示的实施例中为九个)混合器叶片30承载在壁结构22上。各个叶片28具有对应的开口32,而各个叶片30具有对应的开口34。虽然可使用任何适当的构造,但是优选地,混合器16是由模压金属件形成的一体式构件,通过切割各个叶片28、30的周边以同时形成对应的开口32和34,然后使叶片28、30远离混合器16的上游侧36朝向混合器16的下游侧38弯曲,来形成混合器叶片28和30。
优选地,第一组混合器叶片28的大小和形状不同于第二组混合器叶片30的大小和形状。在这点上,在所示的实施例中,可看到第一组混合器叶片28是三角形的,而第二组混合器叶片30是梯形的,第一组混合器叶片28的大小小于第二组混合器叶片30的大小的四分之一。混合器叶片28优选地布置成以便通过利用它们的三角形形状来提供最大密度,同时在开口32之间保留足够量的壁结构20,以在混合器16的预期寿命内保持结构完整性。混合器叶片30优选地布置成周向排列,同时保留足够量的壁结构22,以在混合器16的预期寿命内保持结构完整性。
实验已经显示,壁结构20、叶片28和开口32往往使添加剂雾化和/或蒸发,并且壁结构22、叶片30和开口34往往使结合的排气/添加剂流旋动,与更传统的混合器相比,这两个现象结合起来,由系统10提供了增强的混合和更好的还原效率。
参照图6-8所示的混合器16的备选实施例,可看到盘形壁结构20的直径已经减小,这导致锥形壁结构22的大小的对应的增加,并且已经消除了叶片28且用两个半月形开口40来代替叶片28,开口40由壁结构22的细长的长方形部分42分开,并且由壁结构22的环形部分44包围。各个叶片30的大小已经增大了对应于壁结构22的大小增大的量,并且叶片的数量已经从九个减少到六个。在这点上,重要的是注意到叶片30的数量将高度地取决于各种应用的特定参数,包括流径12的内直径或尺寸、期望的背压和期望的混合量。优选地,各个叶片30包括一排穿孔46,穿孔46在图6-8中被显示为圆形开口,其意在增强添加剂和排气的混合。应力消除部48优选地提供于与壁结构22连接的各个叶片30的侧部的各端处。
如在图5和9中最佳地看到的那样,对于混合器16的两个实施例而言,叶片28和30相对于相关联的壁结构20或22具有范围可为从15°至90°的弯角α(交角)。再次,特定的弯角将高度地取决于各种应用的特定参数,包括例如期望的背压和混合量。另外,如在图10和11中看到的那样,还可行的是沿着叶片30的径向长度分开叶片30中的一个或多个,以形成子叶片30a和30b,叶片30a中的一个具有第一弯角αa,而叶片30b中的另一个具有弯角αb,弯角αb不同于弯角αa,以便进一步增强混合。
应当理解,虽然在本文中显示了混合器16的优选实施例,但是,取决于各种应用的特定参数,存在可能合乎需要的许多可行的修改。例如,对于两组叶片28和30中的任意一组或两者而言,其它形状、定向、数量、布置、大小和相对大小可为合乎需要的,通过图2-5中的叶片30和图6-8中的叶片30之间的差异显示了其一个实例。在这点上,应当理解,对于一些应用,穿孔46在图2-5的叶片30中可为合乎需要的,并且对于一些应用,从图6-8的实施例中的叶片30中消除穿孔44可为合乎需要的。类似地,在任一实施例中,可对叶片28和30中的任一个提供应力消除部48,或者可按各种应用的需要所规定的那样取消应力消除部48。作为另一个实例,对于一些应用,可能合乎需要的是壁结构22的锥角比图2-8的实施例中所示的更陡或更浅。类似地,可基于任何特定应用的参数来改变壁结构20的大小。
