Description
技术领域technical field
本实用新型涉及一种尾气处理装置，特别是一种适用于柴油汽车的尾气处理装置，属于汽车技术领域。The utility model relates to an exhaust gas treatment device, in particular to an exhaust gas treatment device suitable for diesel automobiles, and belongs to the technical field of automobiles.
背景技术Background technique
随着汽车业的快速发展，汽车逐渐成为了人们日常生活中不可或缺的产品，它在为人们带来便利的同时，也不可避免地带来了一系列环境问题。尤其是尾气污染，它是直接导致空气污染的“头号杀手”，严重威胁人们的身体健康。汽车排放的尾气污染物(一氧化碳、碳氢化合物、氮氧化合物、二氧化硫、烟尘微粒、臭气)会引起人体多种疾病、加重温室效应、造成能源消耗。目前，对车用柴油机进行尾气处理时，主要采用NH3-SCR系统来还原氮氧化物，但该系统常常会存在催化剂硫中毒问题。因此，随着对汽车尾气排放标准日益严格，该技术已不能适应目前高标准的排放要求。为此，业内人士急切的期望能够通过其他技术方案，解决尾气处理问题。With the rapid development of the automobile industry, the automobile has gradually become an indispensable product in people's daily life. While it brings convenience to people, it also inevitably brings a series of environmental problems. Especially exhaust pollution, it is the "number one killer" that directly leads to air pollution, seriously threatening people's health. Exhaust gas pollutants (carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide, soot particles, and odor) emitted by automobiles can cause various diseases in the human body, aggravate the greenhouse effect, and cause energy consumption. At present, the NH3-SCR system is mainly used to reduce nitrogen oxides in the exhaust gas treatment of vehicle diesel engines, but this system often has the problem of catalyst sulfur poisoning. Therefore, with the increasingly stringent emission standards for automobile exhaust, this technology can no longer adapt to the current high standard emission requirements. For this reason, people in the industry are eagerly looking forward to solving the problem of exhaust gas treatment through other technical solutions.
另外，在汽车排放尾气的同时，其尾气管壁受热会释放出大量的热能，为避免热量较高，通常是利用汽车行进过程中风能，对其进行降温处理的。这种处理方式虽然能够有效的降低排气管的热量，但同时也造成一定的能源浪费。所以，如何能够在防止排气管温度过高的同时，又能实现对其管壁处的热能进行回收利用，也同样成为了业内人士需要解决的问题。In addition, when the exhaust gas is emitted by the automobile, the wall of the exhaust pipe will release a large amount of heat energy when it is heated. In order to avoid high heat, the wind energy is usually used to cool down the automobile when it is running. Although this treatment method can effectively reduce the heat of the exhaust pipe, it also causes a certain waste of energy. Therefore, how to realize the recovery and utilization of heat energy at the pipe wall while preventing the temperature of the exhaust pipe from being too high has also become a problem to be solved by people in the industry.
