Huachen Aike Diesel Exhaust Filter Burns 90% of Particulate Matter

Recently, Huaqin Rubber Industry Group held the "Huaqin Aike - Diesel Vehicle Exhaust Filter (DPF) Technology Promotion Conference and Press Conference" at Diaoyutai State Guesthouse in Beijing. The world's largest conveyor belt manufacturer and a well-known domestic tire manufacturer from Quzhou City, Shandong Province, brought a diesel exhaust gas filtration technology that meets China's national conditions, indicating that Hua Qin has officially entered the environmental protection industry.

Huaqing Aike Diesel Exhaust Gas Filtration Technology developed by Huaqin Aike Environmental Technology Co., Ltd., a subsidiary company of Huaqin Group, adopts a wall-flow external purification program. Its core technology is the use of silicon carbide materials and detachable filter cores. The diesel fuel additive acts as a catalyst to reduce the ignition temperature of particles that normally require combustion above 600°C to below 350°C to accelerate the combustion of particulate matter collected in the filter (regeneration process). This technology can reduce particulate matter content in the exhaust gas of diesel engines by more than 90%. The product life span is 500,000-600,000 kilometers, and the filter can still be recycled after replacing materials such as filter cartridges. The cost is only equivalent to that of foreign products. Half of it.

According to Wang Weiqin, deputy general manager of Huaqin Group, the advantages of Huajin Aike Diesel Exhaust Gas Filter Technology are: First, its good sulfur resistance, that is, it has good adaptability to the sulfur content of diesel; Second, it is small and only It is necessary to use Huaqin's exhaust filter to replace the existing muffler for installation. Third, there is no additional fuel consumption. In terms of installation, the filter can set specific specifications and positions of the filter according to features such as engine displacement, power, and emission level, as well as characteristics of the vehicle's size, chassis, and noise level, with considerable flexibility and adaptability. Sex. For daily use and maintenance, basic maintenance is only based on the number of kilometers traveled and the time of use of the vehicle. A regular inspection of the system's operation is performed every 25,000 kilometers or 500 hours, and every 60,000 kilometers or 1,000 hours (approximately one year) The filter can be cleaned once. The consumption of additives that people are more concerned about is that every 1,000 liters of diesel consumed consumes 1.4 liters of catalytic additives, that is, the consumption rate of additives is 0.14%. Vehicles can supplement the additive tanks according to mileage.

In addition, Huaqing Aike Diesel Exhaust Filter also has an active regeneration function when the temperature of the exhaust gas is too low, that is, the electric heating device controlled by the electronic control unit (E鄄CU) can be started automatically to burn particles in the filter. Provide additional heat source for active regeneration. Under normal circumstances, when the exhaust temperature exceeds 350°C and exceeds 5% of the overall operating time, the particulates accumulated in the filter can be automatically burned into carbon dioxide gas under the action of the fuel additive for passive regeneration.

From the perspective of users' usage, Huaqing Aike's diesel vehicle exhaust filters received performance tests and test operations in Beijing, Shanghai, Xining, and Jining, respectively. Including the 30,000 km performance stability assessment test on different commercial vehicles in Beijing, the diesel vehicle demonstration project test in Shanghai, the smoke detection in Xining, and the actual traffic conditions of more than 5,000 buses and municipal engineering vehicles in Jining. Test and so on.

As a representative of the customer, Wang Qiang, Minister of the Machinery Group of the First Development Group, which mainly engaged in road maintenance, road greening, and maintenance of road traffic facilities, introduced exhaust gas emissions after modifying Huachen Aike products selected from 17 conservation vehicles in May 2010. Significantly improved, no product failure and failure, engine power does not drop, long-term use of the product engine fuel consumption and flat before installation. In general, through the installation and use of Huachen Aike products, the company has significantly extended the service life of existing vehicles and avoided scrapping old vehicles in advance.

A set of data provided by Huaqin indicates that after installing Huaqin Aike Automotive Exhaust Filter, while reducing the content of particulate matter in diesel engine exhaust by more than 90%, it can reduce over 90% of carbon monoxide and 69% of hydrocarbon Compound emissions without increasing secondary pollution. Taking a country-level 193-kilowatt diesel engine as an example, taking 8 hours of work per day, 330 days a year can reduce particulate emissions by 68 kilograms. If this figure is applied to the country’s existing 3.6 million remodelable vehicles, the social benefits achieved are enormous.

In 2009, Huaqin Aike Environmental Technology Co., Ltd., established by Hua Qin Group, specializes in the research, development and production of environmental protection technologies and products. The reporter learned that the Huaqing Aike Diesel Exhaust Filter Project has a designed capacity of 500,000 sets per year, a set of 100,000 sets, and a total investment of 1 billion yuan. After full production, Huachen Aike will become the largest and most technologically advanced diesel vehicle exhaust gas filter manufacturer and distributor in China.

The National Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Environmental Protection, the Beijing Municipal Environmental Protection Bureau, the China Environmental Protection Industry Association, the Beijing Municipal Environmental Protection Industry Association and other relevant governments and associations attended the conference. From the speeches of some leaders and experts, it can be seen that under the dual pressures of China's energy and environment, through the use of technologies such as Huaqin Aike filter, the energy-saving, environmentally-friendly diesel power is widely promoted in China, especially The popularity of passenger vehicles should be put on the agenda as soon as possible.
