Description

一种DOC-DPF-SCR总成装置
技术领域
本发明涉及柴油机后处理系统，更具体地说，涉及一种DOC-DPF-SCR总成装置。
背景技术
柴油机DOC-DPF-SCR总成即氧化催化器、柴油颗粒捕集器及选择性催化还原系统的集合，用于对柴油机的尾气进行处理。
就现有技术而言，传统的DOC-DPF-SCR装置仅集成了温度传感器座、氮氧传感器座、尿素喷嘴座等，并未对其相应的传感器、附件及线束等进行安装，而需要主机厂家自行装配。但是，在实际的装配过程中，因欧VI后处理系统包括4个温度传感器，分别为DOC前温度传感器、DOC后温度传感器、DPF后温度传感器、SCR后温度传感器，故安装时易出现顺序接错的问题，导致DPF无法正常再生、尿素无法正常喷射；同时，因各个传感器及执行器的线束没有统一的归口，故容易使线束出现高温烤化的现象；且现有的后处理系统中DOC-DPF总成与SCR总成为连接一体的设计，二者无法分离，导致整车布置的适应性较差，对空间要求苛刻，适配车型单一。
因此，如何满足DOC-DPF-SCR总成装配的普适性，是现阶段该领域亟待解决的难题。
发明内容
有鉴于此，本发明的目的在于提供一种DOC-DPF-SCR总成装置，该装置能够保证DOC-DPF-SCR总成装配的普适性，解决了现阶段该领域的难题。

以下，参照附图对实施例进行说明。此外，下面所示的实施例不对权利要求所记载的发明内容起任何限定作用。另外，下面实施例所表示的构成的全部内容不限于作为权利要求所记载的发明的解决方案所必需的。
本具体实施方式提供的DOC-DPF-SCR总成装置，请参见图1-图5；包括DOC-DPF总成和SCR总成3，且DOC-DPF总成与SCR总成3为可拆装的连接；故在实际装配时，可以在DOC-DPF总成与SCR总成3之间添加与车体的安装空间相匹配的连接件21，以适应不同的整车装配。如图3-图5所示，该连接件21可以为直线型、U型、弯折型等。由以上内容可知，该DOC-DPF-SCR总成装置可以根据整车的空间进行设计安装，以适应各种不同类型的车型，安装形式多样。因此，本发明提出的DOC-DPF-SCR总成装置，能够保证DOC-DPF-SCR总成装配的普适性，解决了现阶段该领域的难题。
本具体实施方式提供的DOC-DPF-SCR总成装置，还可以包括：DOC前温度传感器4、DOC后温度传感器5、SCR前温度传感器6、SCR后温度传感器7；其中，DOC前温度传感器4和DOC后温度传感器5分别用于检测DOC总成1两端的温度；SCR前温度传感器6和SCR后温度传感器7分别用于检测SCR总成3两端的温度。在实际安装时，因总成装置设计的温度传感器较多，故在实际安装时容易出现顺序接错的现象，导致DPF无法正常再生、尿素无法正常喷射，影响DOC-DPF-SCR总成装置的正常工作；而本装置将各种传感器直接装配到DOC-DPF-SCR总成装置中，免去了厂家对传感器的后续安装，避免了插接顺序出错的现象发生。
本具体实施方式提供的DOC-DPF-SCR总成装置，还包括设置在DOC总成1的压差传感器20。
本具体实施方式提供的DOC-DPF-SCR总成装置，还可以包括分别设置在DOC-DPF-SCR总成的进口8和出口9的、前氮氧传感器10和后氮氧传感器11；该设置进一步简化了总成装置后续装配的工序；还可以包括用于支撑前氮氧传感器10的第一氮氧传感器保护架12、和用于支撑后氮氧传感器11的第二氮氧传感器保护架13；该设置通过架高设计、以避免前氮氧传感器10和后氮氧传感器11的线束被烤化，使线束与总成装置的外壳留有一定的距离，防止线束因高温被烤化。
本具体实施方式提供的DOC-DPF-SCR总成装置，还可以包括设置在SCR总成3的尿素喷嘴14，以及用于支撑尿素喷嘴14的尿素喷嘴保护架15，防止尿素喷嘴14在整车装配或运输过程中出现磕碰。
本具体实施方式提供的DOC-DPF-SCR总成装置，还可以包括线束集成器16，该线束集成器16用于汇总DOC前温度传感器4、DOC后温度传感器5、SCR前温度传感器6、SCR后温度传感器7、前氮氧传感器10、后氮氧传感器11以及尿素喷嘴14的线束，并集成用于装配DOC-DPF-SCR总成装置的插接头。该设计进一步方便了DOC-DPF-SCR总成装置的装配，在实际安装时，本总成装置实现了即插即用的简化安装，将相关线束汇总为插接头、以便直接通过插接的方式进行整车安装；该插接头可以为23针的接插件，便于整车的线束连接及安装固定。
本具体实施方式提供的DOC-DPF-SCR总成装置，还可以包括套装在DPF总成2的第一紧凑型整车安装支架17、和套装在SCR总成3的第二紧凑型整车安装支架18。该设计能够进一步方便总成装置的安装，就紧凑型车辆而言，可以通过上述安装支架直接进行整车安装，简化了总成装置的装配过程。第一紧凑型整车安装支架17和第一紧凑型整车安装支架17可以为同样的设计，如图2所示，上述紧凑型整车安装支架呈环状，套装在DPF总成2和SCR总成3的外周面上，并通过螺栓实现与DPF总成2和SCR总成3的紧固。
本具体实施方式提供的DOC-DPF-SCR总成装置，DOC-DPF总成与SCR总成3可以通过法兰19相连接，亦可以为螺接、卡接等连接形式；在实际的安装时，可以根据车型的需要在DOC-DPF总成与SCR总成3之间添加与车体的安装空间相匹配的连接件21，以适应不同的整车装配。
需要说明的是，本具体实施方式中提到的DOC-DPF总成即DOC总成1和DPF总成2的集成。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
