Description

尿素喷嘴防护装置
技术领域
本发明涉及一种尿素喷嘴防护装置，尤其是一种筒式SCR后处理尿素喷嘴防护装置，属于柴油机尾气处理系统设备技术领域。
背景技术
随着柴油机排放法规的日益严格，尾气后处理技术是必须采用的技术措施。而SCR能够满足国IV及国V排放标准，SCR的基本原理是通过尿素喷射系统（俗称尿素泵）将32.5%浓度的尿素水溶液雾化后喷入排气管中与发动机尾气混合，尿素水溶液经过热解和水解反应生成氨气（NH3），在催化剂的作用下氨气将柴油机尾气中有害的氮氧化合物（NOx）转化为无害的氮气（N2）和水，发动机尾气处理技术SCR路线的首要任务是使尾气与氨雾有效混合并发生化学反应，同时在进入催化剂前保证足够温度。
发明内容
本发明的目的是克服现有技术中存在的不足，提供一种尿素喷嘴防护装置，解决国五阶段SCR后处理集成供货时，避免喷嘴在运输过程中出现损坏。
按照本发明提供的技术方案，所述尿素喷嘴防护装置，其特征是：包括弧形钣金件，弧形钣金件的侧壁上设有避让槽，在弧形钣金件的底端面设有多个快速插接槽。
进一步地，所述弧形钣金件的一侧设置有开口。
进一步地，所述避让槽为2个，对称设置于弧形钣金件上。
进一步地，所述快速插接槽均匀分布于弧形钣金件的底端部。
进一步地，所述快速插接槽为3个。
本发明所述尿素喷嘴防护装置结构简单，设计精良，拆卸方便，在运输过程中可以起保护喷嘴的作用。
附图说明
图1为本发明所述尿素喷嘴防护装置的结构示意图。
图2为本发明所述尿素喷嘴防护装置的使用状态示意图。
附图标记说明：1-弧形钣金件、2-避让槽、3-快速插接槽、4-开口。
具体实施方式
下面结合具体附图对本发明作进一步说明。
如图1所示，本发明所述尿素喷嘴防护装置适用于三孔连接的尿素喷嘴，包括弧形钣金件1，弧形钣金件1的侧壁上设有避让槽2，在弧形钣金件1的底端面设有3个快速插接槽3。
如图1所示，所述弧形钣金件1的一侧设置有开口4；所述避让槽2为2个，对称设置于弧形钣金件1上；所述快速插接槽3均匀分布于弧形钣金件1的底端部。
本发明所述尿素喷嘴防护装置的使用方法，如图2所示，通过快速插接槽3插入三孔喷嘴和喷射底座之间，然后用螺栓拧紧即可，在运输过程中可以保护喷嘴。本发明结构简单，设计精良，拆卸方便，在运输过程中可以起保护喷嘴的作用。
