技术领域
本发明涉及一种尾气后处理装置,属于发动机尾气后处理技术领域。
背景技术
研究表明尾气后处理***(例如选择性催化还原***,SCR***)管路中氨分布的均匀程度对***的整体性能和耐久性能有重要的影响。如果氨分布不均匀会导致局部区域氨过多从而易造成氨泄漏,而在另一些氨稀薄区域造成氮氧化合物(NOx)转化效率过低。长时间氨的不均匀分布会导致催化剂老化不均匀,从而影响催化剂的整体性能。另外,尿素液滴的不均匀分布会造成局部管壁或混合结构温度过低,形成结晶,严重时会堵塞尾气管、导致发动机动力性能下降。
因此,有必要提供一种新型的尾气后处理装置,以解决上述技术问题。
发明内容

作为本发明进一步改进的技术方案,所述壳体设有端盖,所述端盖设有用以容纳尿素喷嘴的凹陷部,所述凹陷部内设有用以安装所述尿素喷嘴的安装座,所述尿素喷嘴用以向所述混合管内喷射尿素。
作为本发明进一步改进的技术方案,所述混合管包括位于所述旋流片的前方的若干开孔,所述开孔靠近所述安装座且与所述第一腔体相连通。
作为本发明进一步改进的技术方案,所述进气管垂直于所述混合管。

具体实施方式
请参图1至图5所示,本发明揭示了一种尾气后处理装置100,用于处理发动机的尾气。所述尾气后处理装置100包括壳体1、安装于所述壳体1内的后处理载体2以及至少部分位于所述壳体1内的混合组件3。
在本发明图示的实施方式中,所述壳体1呈圆筒状,其包括进气管11、出气管12、端盖13以及隔板14。其中所述隔板14以将所述壳体1分成位于所述隔板14一侧的第一腔体141以及位 于所述隔板14另一侧的第二腔体142。在本发明图示的实施方式中,所述后处理载体为选择性催化还原剂且位于所述第二腔体142的下游。所述进气管11与所述第一腔体141连通。所述尾气后处理装置100还包括用以支撑所述进气管11的支撑座15,所述支撑座15焊接在所述壳体1内,所述进气管11穿过所述支撑座15。优选地,所述支撑座15至少部分焊接在所述隔板14上。
所述端盖13设有用以容纳尿素喷嘴(未图示)的凹陷部131,以保护所述尿素喷嘴。所述凹陷部131内设有用以安装所述尿素喷嘴的安装座132,所述尿素喷嘴用以向所述混合组件3内喷射尿素。
所述混合组件3包括架设在所述隔板14上的混合管31以及位于所述第二腔体142内的混合器32。所述进气管11垂直于所述混合管31。所述混合管31包括位于所述第一腔体141内的旋流片311以及位于所述旋流片311的前方的若干开孔312。所述开孔312靠近所述安装座132且与所述第一腔体141相连通。另外,所述混合管31设有穿过所述隔板14以延伸入所述第二腔体142内的延伸部313。
在本发明图示的实施方式中,所述混合器32大致呈圆盘状,其设有面向所述混合管31以迫使气流反向流动的中心部321以及位于所述中心部321***的扰流片322。所述中心部321正对所述延伸部313且与所述延伸部313之间设有间隔。所述中心部321设有向所述混合管31凸起的弧形***部323。所述扰流片322是向外冲压所述混合器32而形成的,所述混合器32设有对应于所述扰流片322的冲孔324。所述冲孔324能够降低背压。当然,根据不同的设计要求,还可以在所述混合器32上设置若干通孔325以进一步降低背压。
当发动机的尾气自进气管11进入第一腔体141时,大部分尾气在旋流片311的导引下旋转进入混合管31,少量的尾气自开孔312进入混合管31中。当满足喷射条件时,尿素喷嘴向混合管31中喷射尿素,雾化的尿素液滴与发动机的尾气一起混合并向下游旋转。随后,在***部323的作用下迫使气流反向(例如向前)流动。扩散之后的气流穿过冲孔324以及通孔325,并藉由扰流片322进行二次混合。如此设置,增加了尿素蒸发的距离和时间,提高了气流混合的均匀性,降低了尿素结晶的风险。
另外,以上实施例仅用于说明本发明而并非限制本发明所描述的技术方案,对本说明书的理解应该以所属技术领域的技术人员为基础,尽管本说明书参照上述的实施例对本发明已进行了详细的说明,但是,本领域的普通技术人员应当理解,所属技术领域的技术人员仍然可以对本发明 进行修改或者等同替换,而一切不脱离本发明的精神和范围的技术方案及其改进,均应涵盖在本发明的权利要求范围内。
