Description

A kind of photocatalysis treatment purification method preventing automobile exhaust pollution

Technical field

The present invention relates to vehicle maintenance service technical field, specially a kind of photocatalysis treatment for preventing automobile exhaust pollution Purification method.

Background technique

Motor-vehicle tail-gas control and improvement have become world's important topic, developed country due to motor vehicle general technical more Advanced, motor-vehicle tail-gas control technology is also relatively advanced, has been achieved with impressive progress, now to ultra-low emission and zero Disposal of pollutants strides forward, and China starts late in this respect, and many control technologies are in exploration and trial period, but positive effort and state Border integrates with；

With external purification two major classes in motor-driven vehicle exhaust purifying method is organic, emission controls by improving combustion is to improve internal combustion engine of motor vehicle knot Structure and combustion position, such as improve fueling injection equipment, using methanol and natural gas as alternative fuel；Internal purification technology can be reduced The production quantity of evil gas need to just be discharged into for the discharge standard for making automotive emission reach stringenter in motor-vehicle tail-gas Before atmosphere, it is translated into innocuous gas using catalytic convention design, emission controls by improving combustion can only reduce the production quantity of pernicious gas, Generated pernicious gas cannot be removed, therefore purification efficiency is not high, and emission controls by improving combustion needs to expend a large amount of financial resources, further Improve cost of the motor vehicle in production, and the pollutant that the exhaust fume catalytics device such as ternary catalyzing unit generates during fabrication A large amount of pollutant can be generated, this also cause built-in purification environmental-protection again not environmentally.

External purification is to carry out treatment and purification to after discharge exhaust gas, outside purification technology because its brilliant actual effect and it is easy due to It is the international motor vehicle tail-gas purifying method generallyd use by favor, catalytic purification is outside current research and the most machine of application Purification style, TiO 2 sol technology can be used for the manufacture of catalyst, and Nano titanium dioxide has extremely strong oxidation also Proper energy power, its application can thoroughly solve the pollution problem of CO and nitrogen oxides in tail gas, and nano photo catalyzed oxidation has been at present As one of most active research direction in the world, nano photo catalyzed oxidation is applied to building for Ecological Road to concerned countries If including nanosizing mixed mud, nano-photo catalytic bituminous pavement, nano-photo catalytic affiliated facility etc., this technology is for effectively dropping Solution motor-vehicle tail-gas, improvement air treating are of great significance.

Although the existing initial achievements of the research of current nano-photo catalytic Ecological Road, the application in entity project also function to Preferable effect, however influenced in actual application by a variety of objective factors, such as nano-photocatalyst material road pavement Adverse effect, such as adsorbed in road surface nitrate, sulfate whether can road pavement material cause corrode, such as application range It is small, pollution degradation species are single, the effective component service life is short etc., therefore urgently exploitation is efficiently, persistently and can widespread adoption Scavenging material and technology.
