Description

一种汽车尾气净化装置
技术领域
本发明涉及一种汽车尾气净化装置，属于汽车零配件技术领域。
背景技术
汽车尾气中含有碳氢化合物、氮氧化合物、一氧化碳、颗粒物等污染物，直接排放汽车尾气对空气质量危害很大，尤其是现在汽车数量急剧增长，尾气排放量也随之增加。汽车尾气中除了化学物质和颗粒物造成空气污染，尾气排放时的噪声也形成噪声污染，尾气排放时温度高，加剧气候变暖趋势，因此有必要对汽车尾气进行净化处理。
发明内容
目的：为了克服现有技术中存在的不足，本发明提供一种汽车尾气净化装置。
技术方案：为解决上述技术问题，本发明采用的技术方案为：
一种汽车尾气净化装置，包括筒体，筒体一端设有尾气入口，与进气管连接，筒体另一端设有尾气出口，与出气管连接；所述进气管与筒体之间设有进气锥管，筒体尾气入口处设有过滤器，所述过滤器由碳化硅纤维编织而成的密过滤网和粗过滤网组合形成；所述过滤器后侧设有蜂窝陶瓷催化层；筒体设有尾气出口的一端内部设有消音器，出气管外部固定设有半导体制冷片。
进一步地，所述密过滤网和粗过滤网的组合顺序为粗过滤网、密过滤网、密过滤网、粗过滤网。
进一步地，所述密过滤网和粗过滤网可折叠。
进一步地，所述消音器包括两个平行隔板，隔板上设有通孔，隔板之间固定有圆柱筒。
进一步地，所述圆柱筒内外壁涂覆吸音涂层。
进一步地，所述蜂窝陶瓷催化层包括蜂窝陶瓷块，蜂窝陶瓷块上布满小孔，小孔内壁涂覆催化剂。
有益效果：本发明提供的汽车尾气净化装置，结构简单，成本低，通过过滤、催化作用可有效去除尾气中的颗粒物、一氧化碳、氮氧化合物等空气污染物；排气管内设置消音器对尾气排放进行消音处理，减少噪音污染；尾气排放前利用半导体制冷片进行降温处理。
附图说明
图1为本发明的结构示意图；
图2为过滤器结构示意图。
具体实施方式
下面结合附图对本发明作更进一步的说明。
本实施例中，参照尾气的进气方向为从前向后的方向。
如图1所示，一种汽车尾气净化装置，包括筒体1，筒体一端设有尾气入口11，与进气管2连接，筒体另一端设有尾气出口12，与出气管3连接。
所述进气管2与筒体1之间设有进气锥管4，增加进气面积；筒体尾气入口处设有过滤器5，所述过滤器5由碳化硅纤维编织而成的密过滤网51和粗过滤网52组合形成，密过滤网51和粗过滤网52的组合顺序为粗过滤网52、密过滤网51、密过滤网51、粗过滤网52，如图2所示，重叠使用粗过滤网和密过滤网，减少表面堵塞；密过滤网和粗过滤网可折叠，折叠后尾气与过滤器的接触面积增大，改善过滤效果。
所述过滤器5后侧设有蜂窝陶瓷催化层6，所述蜂窝陶瓷催化层包括蜂窝陶瓷块，蜂窝陶瓷块上布满小孔，小孔内壁涂覆催化剂。
所述筒体设有尾气出口的一端内部设有消音器7，所述消音器包括两个平行的隔板71，隔板上设有通孔，隔板之间固定有圆柱筒72，圆柱筒72内外壁涂覆吸音涂层。出气管3外部固定设有半导体制冷片8，用于对尾气进行降温。
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。
