Description

包括湿式排气系统的电源管理系统
技术领域
本申请涉及包括排气系统的电源管理系统，更特别地，涉及包括湿式排气系统的电源管理系统。
背景技术
一些现有电源管理系统通常包括排放气体和液体排放物的组合物的排气系统，气体和液体排放物作为操作引擎（尤其是船用引擎）的一部分产生。排放气体和液体排放物的这些类型的系统被称为湿式排气系统（wet exhaust system）。
湿式排气系统中其中一个重要因素是减少操作引擎期间产生的有害排放物的数量。通过包括催化底物（catalytic substrate），通常可以减少现有系统中有害排放物的数量，催化底物拦截有害气体排放物并将其转变成危害较小的元素。
一些现有系统试图在气体被催化底物转变之后在被转变的气体离开湿式排气系统之前冷却排放气体。为了促进被催化底物更有效地转变，排放气体在进入催化底物之前需要保持在尽可能热的状态。
现有电源管理系统其中一个缺点是催化底物由于这种系统的设计过度冷却。催化底物的过度冷却降低了底物的转变效率。
现有电源管理系统的另一个缺点是它们通常相当昂贵且难以制造。与制造这样的系统相关的上涨的成本给生产包括湿式排气系统的产品增加了不希望的成本。

具体实施方式
下文的描述和附图充分地阐述了具体的实施例，以使本领域技术人员能够实施它们。其它实施例可以包含结构的、逻辑的、有关电的、方法的、以及其它的改变。一些实施例的部分和特征可以被包括在或代替其它实施例的部分和特征。权利要求中陈述的实施例囊括那些权利要求的一切可用的等同物。
图1图示说明用于引擎（未示出）的示例性催化组件100。催化组件100包括容纳冷却剂C（例如，海水）的冷却外壳110。图2和图3示出和催化组件100的其余部分分离的冷却外壳110。
催化剂外壳120被配置在冷却外壳110内部，使得冷却剂C在催化剂外壳120和冷却外壳110之间流动。图4和图5示出与催化组件100的其余部分分离的催化剂外壳120。
催化剂底物130（参见图1）被置于催化剂外壳120内部，使得来自引擎的排放气体E流过催化剂底物130。催化剂底物130用于将在排放气体E中发现的有害排放物转变成危害较小的排放物。
在一些实施例中，挡板140被置于催化剂外壳120和冷却外壳110之间催化剂底物130的下游，使得冷却剂C流过挡板140。图6最清楚地示出可以被包括在催化组件100中的示例性挡板140。尽管可以考虑其它材料，但是，作为一个例子，挡板140可以由不锈钢组成。
在图6图示说明的示例性实施例中，挡板140可以包括环形部件141和与环形部件141成一定角度从环形部件141延伸的凸出物142。挡板140包括凸出物142之间的开口143，使得冷却剂流过开口143。
作为一个例子，挡板140可以包括八个开口143，使得冷却剂流过这八个开口143。此外，开口143围绕环形部件141可以以相等的（或不等的）间隔布置。
在一些实施例中，催化剂外壳120包括第一配件（fitting）121，冷却外壳110包括与第一配件121配合的第二配件111，以防止催化剂外壳120相对于冷却外壳110旋转。
在图示说明的示例性实施例中，第一配件121是槽（detent），第二配件111是被插入该槽的凸出物（例如，键（key））。应当注意的是，在各自的催化剂外壳120和冷却外壳110中使用的第一配件121和第二配件111的类型部分取决于催化组件100的总体设计。
考虑可选的实施例，其中，第一配件121是凸出物，第二配件111是容纳该凸出物的槽。在还有的其它实施例中，催化剂外壳120上的第一配件121可以被插入（或容纳于，取决于设计）冷却外壳110上的第二配件111，直到第一配件121和第二配件111防止催化剂外壳120进一步插入冷却外壳110。
在一些实施例中，催化组件100进一步包括被固定在催化剂外壳120中的环形槽125内的控制部件150，以固定催化剂外壳120内部的催化剂底物130。图7-图10图示说明示例性磁盘状环150，该环150允许废气流过环150进入催化剂底物130。尽管应当注意的是可以考虑其它材料，但是，作为一个例子，环150可以由不锈钢组成。
在图示说明的示例性实施例中，环形槽125围绕催化剂外壳120的整个内表面延伸。图7示出插入催化剂外壳120之前的环150。图8示出插入催化剂外壳120之后但在插入环形槽125之前的环150。图9和图10示出插入催化剂外壳120中的环形槽125之后的环150。
现在还参考图11，另一个示例性实施例涉及组装催化剂组件100的方法200。所述方法200包括[210]将催化剂底物130插入催化剂外壳120，和[230]将催化剂外壳120插入冷却外壳110，使得冷却剂C能在催化剂外壳120和冷却外壳110之间流动。
所述方法200进一步包括[240]将冷却外壳110安装到引擎歧管（engine manifold）（未示出）。所述方法可以进一步包括[220]在将催化剂外壳120插入冷却外壳110之前将挡板140插入冷却外壳110，使得挡板140在催化剂底物130的下游且冷却剂流过挡板140。
在一些实施例中，[230]将催化剂外壳120插入冷却外壳110可以包括使催化剂外壳120上的第一配件121与冷却外壳110上的第二配件111配合。作为一个例子，使催化剂外壳120上的第一配件121与冷却外壳110上的第二配件111配合可以包括将催化剂外壳120上的凸出物插入冷却外壳110上的槽，以防止催化剂外壳120相对于冷却外壳110旋转。
应当注意的是，考虑实施例，其中，使催化剂外壳120上的第一配件121与冷却外壳110上的第二配件111配合可以包括将冷却外壳110上的凸出物插入催化剂外壳120上的槽，以防止催化剂外壳120相对于冷却外壳110旋转。此外，使催化剂外壳120上的第一配件121与冷却外壳110上的第二配件111配合可以包括防止催化剂外壳120进一步插入冷却外壳110。
在此描述的催化组件100和方法200可以用于在操作引擎期间防止催化底物130过度冷却。防止催化底物130过度冷却可以提高催化底物130的转变效率。
此外，在此描述的催化组件100和方法200可以促进成本降低和可制造性。降低与制造催化组件100相关的成本可以降低生产包括催化组件100的产品的成本。
提供摘要以符合要求摘要的37C.F.R.部分1.72（b），摘要允许读者确定技术公开的本质和主旨。可以理解，摘要不用来限制或解释权利要求的范围或含义。权利要求在此被并入详细的描述中，且每项权利要求本身是单独的实施例。
