According to "Xinmin Evening News" reported on the 13th, automobile exhaust is the main source of air pollution in modern cities. It is necessary to cut off the "black tail", mainly relying on the installation of a three-element purifier containing a catalyst to make the harmful gas into a gas suitable for discharge into the atmosphere.
At present, China needs to support nearly 20 million sets of various types of exhaust gas purifiers each year. Due to the lack of relevant technologies and equipment in China, most of the purifiers are imported directly from abroad, or imported from abroad to produce production equipment. The total price of a set of imported purifier production lines is as high as 45 million yuan, which greatly increases the manufacturing cost of the production enterprises.
In 2003, the key project of the Shanghai Municipal Science and Technology Commission, the development of key technologies and equipment for the automated production line of bundled three-way catalytic converters, was officially launched. The project is jointly completed by Shanghai Jiaotong University and Shanghai Lianeng Electromechanical Co., Ltd. and Shanghai Fojiya Honghu Exhaust System Co., Ltd. in accordance with the industry-university research mode of "instituting technical research, enterprises jointly manufacturing, production and demonstration applications" .
Professor Liu Chengliang from the School of Mechanical and Power Engineering of Shanghai Jiaotong University told the reporter that this production line consists of 8 major units. The production process combines more than 20 processes and hundreds of actions. The total development cost is only 5 million yuan. Has created an output value of more than 30 million yuan for the trial unit.
The first domestic automobile exhaust gas purifier production line developed by Shanghai has passed the acceptance of experts hosted by the Shanghai Science and Technology Commission.
