Description
技术领域technical field
本实用新型涉及一种消声器，特别涉及一种降低汽车尾气颗粒物排放的消声器。The utility model relates to a muffler, in particular to a muffler for reducing the discharge of automobile tail gas particles.
背景技术Background technique
随着近年来雾霾等环境问题的频频出现，引起了人们的广泛关注，颗粒物PM10,PM2.5等指标也进入大家的视野，由此引发的各类呼吸道肺部疾病患者也成为各大医院门诊的常客，随着汽车保有量的不断增加，汽车尾气排放则是颗粒物排放的重大祸首之一，随时拥堵的道路默默注视着漫天的颗粒物随风扩散。科学分析表明，汽车尾气中含有上百种不同的化合物，其中的污染物有固体悬浮微粒、一氧化碳、二氧化碳、碳氢化合物、氮氧化合物、铅及硫氧化合物等。一辆轿车一年排出的有害废气比自身重量大3倍。英国空气洁净和环境保护协会曾发表研究报告称，与交通事故遇难者相比，英国每年死于空气污染的人要多出10倍。With the frequent occurrence of environmental problems such as smog in recent years, it has aroused widespread concern, and indicators such as PM10 and PM2.5 have also entered everyone's field of vision. Frequent customers of outpatient clinics, with the continuous increase in the number of cars, vehicle exhaust emissions are one of the major culprits of particulate matter emissions. The congested roads are always watching silently as the particulate matter diffuses with the wind. Scientific analysis shows that automobile exhaust contains hundreds of different compounds, among which pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, and sulfur oxides. The harmful exhaust gas emitted by a car in a year is three times larger than its own weight. The British Association for Clean Air and Environmental Protection once published a research report saying that compared with the victims of traffic accidents, the number of people who die from air pollution in the UK is 10 times more than that of the victims of traffic accidents every year.
针对汽车尾气颗粒物排放的控制研究较少，目前治理汽车尾气采取的处理技术措施主要有：强制使用无铅汽油、强制安装三元催化器等，使汽车尾气排放得到一定程度的控制。但三元催化装置只是将汽车尾气排出的CO、HC和NOx等有害气体通过氧化和还原作用转变为无害的二氧化碳、水和氮气的催化。仅有5%的颗粒物吸附在三元催化装置及消声器的隔离盘之中，95%以上的颗粒物随尾气排放到大气中，对我们生活的环境造成巨大的破坏，环保和节能是当今和未来经济社会发展中人类面临的重大课题。There are few studies on the control of vehicle exhaust particulate matter emissions. At present, the treatment technical measures taken to control vehicle exhaust mainly include: mandatory use of unleaded gasoline, mandatory installation of three-way catalytic converters, etc., so that vehicle exhaust emissions can be controlled to a certain extent. But the three-way catalytic device is only a catalysis that converts harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. Only 5% of the particulate matter is adsorbed in the three-way catalytic device and the isolation plate of the muffler, and more than 95% of the particulate matter is discharged into the atmosphere with the exhaust gas, causing huge damage to our living environment. Environmental protection and energy saving are the key to the current and future economic Major issues facing human beings in social development.
