    National Technology Center



Summary

Kelin was established nearly 40 years ago and has always devoted itself to the field of air pollution control equipment. It has optimized bag filter technology worldwide. The company has a national environmental design qualification and qualification certificate for foreign contracted projects. It is a technology-based enterprise that also has a national-level enterprise technology center and a postdoctoral workstation. It is a vice president of the China Environmental Protection Industry Association and a chairman of the bag filter committee.

In 2012, the company was jointly recognized by the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Finance, the General Administration of Customs and the State Administration of Taxation to become a state-level enterprise technology center.

      The company's state-level technology center specializes in the design, research, development, consulting, and general contracting of atmospheric environmental protection projects and equipment. Currently, it has more than 100 R&D and design personnel, including 2 special allowances from the State Council, 4 researchers, and 4 professor-level senior engineers. more than 60 Senior engineers .

National Technology Center of the company has been established long—term friendly technical cooperation relationship with Tsinghua University, Zhejiang University, Southeast University, Nanjing University of Science and Technology, Jiangnan University, Suzhou University of Science and Technology and the Netherlands Institute of Technology, Japan SHINWA, New Japan Railway, Japan Spender, Denmark SAMTKE, United States EEC, Siemens VAI and PW in Germany

The company's state-level technology center has an atmospheric environmental control product testing and testing center to conduct test tests on operating conditions and new product development. The main testing equipment of the testing center are 95 units (sets), a professional dust testing laboratory and a dedicated pulse jet testing device are built. The experimental device adopts a 1:1 specification ultra-long filter bag for a variety of dust stripping sprays. Blowing technology and experimental research on diversion technology provide important guarantees for the design and research and development of filter equipment and provide customers with important services such as on-site data acquisition testing

The company's state-level technical center has a digital design and simulation laboratory, and explores and continuously optimizes the distribution technology of the air flow field of the filter. The professional CFD fluid analysis software can be used to know the distribution of air flow before and after diversion, so that the diversion design of the gas flow field is more scientific and reasonable. At the same time, it provides the best solution for increasing the life of the filter bag and reducing the structural resistance.

       At present, the technology center has developed more than 30 series and more than 400 specifications of filter and environmental protection equipment;

Successfully developed and designed: large-scale electric furnace filter, dry bag filter of blast furnace gas, dry and wet desulphurization by sintering, dry-type desulfurization, denitrification and filter for industrial coal-fired boilers, electric bag dust removal, household garbage, hazardous waste, sludge, and titanium dioxide , Light bulb production line Ultra-fine particle dust removal and recovery of the total package project;

      More than 30 high-tech products with independent intellectual property rights have been developed, and a number of technologies have been listed in the list of major environmental protection technology and equipment of the Ministry of Industry and Information Technology;

Kelin successively undertook the national science and technology researchproject, the national major equipment nationalization technology innovation project, the 863 project, and the Jiangsu major scientific and technological achievements transformation project;

     There are dozens of "National Key New Products" and "National Torch Plan Projects";

The Ministry of Industry and Information Technology has won the title of the first batch of air pollution control regulation companies, and the Brand Top 50 of Jiangsu Provincial Autonomous Industry ;

Obtained qualifications of the Ministry of Housing and Urban-Rural Environmental Protection Class B design and 3A class enterprise credit, EU CE, EN1090,

Host or participate in the formulation of 7 national standards, 4 industry standards and 14 enterprise standards;

Nearly 100 patents were developed and more than 60 papers were published.
