Description

一种汽车尾气净化器
技术领域
本发明涉及汽车环保领域，具体是指一种汽车尾气净化器。
背景技术
汽车排出的尾气成分主要有碳氢化合物、氮氧化合物、一氧化碳、颗粒碳等。三元催化主要是将汽车尾气中的碳氢化合物、氮氧化合物、一氧化碳等有害气体通过氧化和还原作用转变为无害的二氧化碳、水和氮气。但是催化剂表面沉积颗粒会使催化剂表面活性降低甚至失效，因此大多数尾气净化器会在催化剂载体前加设过滤装置。但是现在采用的过滤装置上沉积颗粒碳的效果不是太好，容易堵塞，因此需要频繁更换过滤装置，大大降低了净化器的使用寿命。
本发明为了弥补现有技术的不足，提供了一种净化效果好、使用寿命长的汽车尾气净化器。
为解决上述技术问题，本发明提供一种汽车尾气净化器，包括固定装置、进气管、烟气净化室、过滤室、三元催化室和排气管，其特征在于，所述固定装置连接尾气排放端，所述进气管将汽车燃烧箱内产生的尾气引入至烟气净化室，所述烟气净化室与过滤室相连接，所述过滤室与三元催化室之间相连接，所述三元催化室连接排气管。
进一步的，所述烟气净化室上部设有注液口，所述注液口设有盖子可以打开闭合，所述烟气净化室下部设有排液口和排液阀，所述排液口由排液阀控制开关，所述烟气净化室内的液体通过排液口排除到烟气净化室之外。
进一步的，所述烟气净化室中注入的液体为高锰酸钾溶液。
进一步的，所述过滤室为蜂窝状陶瓷网或蜂窝状氧化铝网。
通过采用上述技术方案，本发明所达到的技术效果为：该净化器，结构简单，不易堵塞，净化效果好，使用寿命也得到大大的提高，同时降低了汽车的噪音污染，又达到了较好的减震效果。
附图说明
图1为本发明的结构示意图。
图中，1为固定装置，2为进气管，3为烟气净化室，4为过滤室，5为三元催化室，6为排气管，7为注液口，8为排液口，9为排液阀。
具体实施方式
下面结合附图对本发明的汽车尾气净化器作进一步说明：
实施例：汽车尾气净化器包括固定装置1、进气管2、烟气净化室3、过滤室4、三元催化室5和排气管6，固定装置通过螺纹连接尾气排放端，所述的进气管将汽车燃烧箱内产生的尾气引入至烟气净化室，然后依次通过过滤室、三元催化室，并通过排气管将净化的尾气排放到空气中。
所述烟气净化室上部设有注液口7，所述注液口设有盖子可以打开闭合，所述烟气净化室下部设有排液口8和排液阀9，所述排液口由排液阀控制开关，所述烟气净化室内的液体通过排液口排除到烟气净化室之外。
所述烟气净化室中注入的液体为高锰酸钾溶液。
所述过滤室为蜂窝状陶瓷网或蜂窝状氧化铝网。
在使用过程中，汽车排放的尾气通过进气口引入烟气净化室，烟气净化室内的高锰酸钾溶液有效的吸收二氧化硫气体，以及固体颗粒，然后通过过滤室进一步的去除固体颗粒，最后经过过滤的尾气通过三元催化室将碳氢化合物、氮氧化合物、一氧化碳等转化为二氧化碳、水和氮气排入到大气中。
本发明的汽车尾气净化器，结构简单，不易堵塞，净化效果好，使用寿命也得到大大的提高，同时降低了汽车的噪音污染，又达到了较好的减震效果。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
