On the occasion of the third anniversary of the Wenchuan earthquake, the reporter went deep into the disaster area in Sichuan and learned that the chemical industry in the earthquake-hit areas of Deyang and Mianyang in the January-April months this year surpassed the Sichuan industrial average by 10 percentage points. In the three-year post-disaster reconstruction, Sichuan chemical companies built one national key laboratory and six engineering and technology development centers, and obtained more than 190 national invention patents. 124 scientific research achievements passed the appraisal, and technological innovation became the Sichuan chemical company's reconstruction after the disaster. Endogenous power.
Sichuan Longxi Group Technology Center was recognized as a national enterprise technology center in the post-disaster reconstruction. Li Jiaquan, chairman of the group, told the reporter that through technological innovation, the center has developed a “sulfur-phosphorus-titanium†circular economy industrial chain with independent intellectual property rights, which effectively solved the environmental problems of the titanium dioxide production process and enabled the byproduct to be used effectively. , To become a circular economy industry model with Long Yao characteristics. After several years of technological transformation, reconstruction and expansion, the Longyan Group's rutile titanium dioxide unit production has ranked first in the country. During the reconstruction, Longxi Group also intervened in the bio-chemical technology industry and became the only supplier of industrial production of S-sensitine in the world.
The Sichuan Meifeng Group established the Technology and Economic Research Institute the second year after the earthquake and focused on promoting the development and application of new technologies. In the 3-year reconstruction, Meifeng Group independently researched and developed 7 key urea production core patent technologies such as large-particle urea granulation method and evaporative system evaporating system vacuum method; 3 results of gas head large-scale synthetic ammonia urea plant technology and energy optimization. Appraisal by Sichuan Provincial Department of Science and Technology; Self-stripping type sub-tower applied to a full-cycle decomposing technology of aqueous solution to make the traditional device to consume 1 ton of urea steam consumption, and the energy consumption is reduced to the lowest; the urea prilling tower dust washing recovery technology is listed as The national recycling economy supporting technology; integrated synthesis and application technology of the gas head synthetic ammonia / urea plant wastewater treatment for the company to increase the annual benefit of 6.83 million yuan.
Sichuan Bluestar Machinery Co., Ltd. quickly adjusted its product structure after the earthquake and moved onto the fast lane of development. In April of this year, Bluestar Machinery developed a new material for Abe alloy steel railroad frogs that passed the national certification, rewriting the history of high manganese steel materials used in China's speed-up railways and heavy-duty railroad frogs. In addition, Bluestar Machinery actively cooperates with research institutes to rapidly transform scientific research results into productivity. They used the five-tube-plate combined ammonia cooler in the 50,000-ton/year melamine urea scrubber tower and the 200,000-ton/year ammonia synthesis plant produced by Tsinghua University's energy-saving gas-phase quenching and crystallization technics to fill the gap in localization; The 150,000 tons/year double pressurized nitric acid absorption tower and 288m3 stainless steel spherical tank produced by advanced technology are the first in China.
