Description

一种汽车尾气净化器
技术领域
本发明涉及汽车尾气处理技术领域，特别涉及一种汽车尾气净化器。
背景技术
随着经济的发展，汽车的数量越来越多，汽车尾气的污染问题越发严重，因此有必要对汽车尾气进行净化处理。汽车尾气中的主要有害成分为碳颗粒、NOx，CO、CO2、SO2等，而市面上的汽车尾气净化器往往无法有效去除这些成分。
发明内容
本发明的目的在于提供一种汽车尾气净化器，该净化器能够有效去除尾气中的有害成分。
为了达到上述目的，本发明采取了以下技术方案：
一种汽车尾气净化器,包括壳体，壳体前端设置有进气管，进气管通过连接套与汽车的排气管连接，壳体后端设置有出气管；壳体内部前端设置有过滤网，中部设置有反应装置，后端设置有雾化器；过滤网下方设置有集尘箱，集尘箱与过滤网前方的壳体内部空间连通；反应装置包括多块依次间隔排布的上隔板和下隔板，这些上隔板和下隔板把壳体内中部空间分隔为波浪形流道，流道内沿气流流向依次储存有还原催化剂、制氧剂、氧化催化剂；雾化器上方设置有储液箱，储液箱内装有Ca（OH）2溶液，雾化器的入口与储液箱连通，雾化器下方设置有集液斗，该集液斗下端的出口与一个集液箱连接。
所述的汽车尾气净化器中,所述过滤网倾斜设置，其上端往连接套方向倾斜。
所述的汽车尾气净化器中, 进气管上设置有消声器。
所述的汽车尾气净化器中,储液箱内设置有液位传感器，储液箱上端设置有报警器，液位传感器与报警器电性连接。
所述的汽车尾气净化器中,所述还原催化剂为铁。
所述的汽车尾气净化器中,所述制氧剂为过氧化合物。
所述的汽车尾气净化器中,所述氧化催化剂为LiO2。
有益效果：
本发明提供了一种汽车尾气净化器，尾气先经过过滤网滤除较大颗粒，然后在反应装置中依次与还原催化剂、制氧剂、氧化催化剂发生反应转换为H2O和CO2，最终CO2会与雾化的Ca（OH）2溶液反应生成CaCO3沉淀下来。该净化器能够有效去除尾气中的有害成分。
附图说明
图1为本发明提供的汽车尾气净化器的结构示意图。
具体实施方式
本发明提供一种汽车尾气净化器，为使本发明的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
请参阅图1，本发明提供的一种汽车尾气净化器,包括壳体1，壳体前端设置有进气管2，进气管通过连接套3与汽车的排气管90连接，壳体后端设置有出气管4；壳体内部前端设置有过滤网5，中部设置有反应装置6，后端设置有雾化器7；过滤网下方设置有集尘箱8，集尘箱与过滤网前方的壳体内部空间连通；反应装置6包括多块依次间隔排布的上隔板61和下隔板62，这些上隔板和下隔板把壳体内中部空间分隔为波浪形流道，流道内沿气流流向依次储存有还原催化剂63、制氧剂64、氧化催化剂65；雾化器上方设置有储液箱9，储液箱内装有Ca（OH）2溶液，雾化器的入口与储液箱连通，雾化器下方设置有集液斗10，该集液斗下端的出口与一个集液箱11连接。
尾气先经过过滤网滤除较大颗粒；然后在反应装置中先与还原催化剂反应把氮氧化物分解为氮气，再与制氧剂反应把CO2、SO2、NO2转换为碳酸盐、硫酸盐、硝酸盐并产生大量氧气，这些氧气与氧化催化剂将CO转换为H2O和CO2，最终CO2会与雾化的Ca（OH）2溶液反应生成CaCO3沉淀下来。该净化器能够有效去除尾气中的有害成分。
进一步的,所述过滤网5倾斜设置，其上端往连接套3方向倾斜，以便颗粒落入集尘箱。
本实施例中, 进气管2上设置有消声器12，以降低噪声。
进一步的,储液箱9内设置有液位传感器13，储液箱上端设置有报警器14，液位传感器与报警器电性连接。当液位过低时发出警告。
具体的,所述还原催化剂63为铁；所述制氧剂64为过氧化合物；所述氧化催化剂为LiO2。
可以理解的是，对本领域普通技术人员来说，可以根据本发明的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本发明所附的权利要求的保护范围。
