Possessing the international first patent to fill the gap of Domestic Technology
The independent innovation of DEAR Airbus leads the green transformation
The original report is as follows:
Zhao Hailong, a reporter from our correspondent, reported that in 2006, Kaifeng air separation plant broke the foreign monopoly and ended the long term history that domestic large air separation plant relied on imports. Eight years later, Kaifeng DEAR air separation Industrial Co., Ltd. (hereinafter referred to as DEAR air separation) became the leader of the "green" development of the International Air separation industry. On March 17, the journalist learned from DEAR air separation that recently, the two utility model patents of this enterprise, energy-saving air separation nitrogen water precooling system and energy-saving oxygen generator, were authorized by the State Intellectual Property Office, among them, the energy-saving air separation nitrogen water precooling system technology is the first in the world, while the energy-saving oxygen generator technology fills the gap in China. The successful research and development of these two technologies marks that our country is at the forefront of the world in the field of energy saving and environmental protection air separation equipment manufacturing.
In recent years, the pace of transformation and upgrading of domestic industries such as metallurgy, coal and electricity, coal chemical industry, steel and so on has been accelerating, and the air separation industry, as an important accessory, is facing new development challenges. Because the manufacturing technology of high-end air separation plant has been monopolized by foreign enterprises for a long time, domestic air separation plant does not have an advantage in technology research and development, especially in the field of energy saving and environmental protection air separation plant manufacturing technology, it lags behind the international advanced level, it restricts the development of domestic air separation industry. In order to achieve a breakthrough in the field of energy saving and environmental protection air separation equipment manufacturing technology, before that, many domestic air separation companies made bold attempts, but the effect was not ideal.
"Take the oxygen generator as an example, the traditional manufacturing process is very complicated, and there are many technical bottlenecks. Compared with the similar products abroad, because they don't have competitive advantages in product performance, even if it is produced, it is hard to be recognized by the market ." Xu Hao, the chief engineer of DEAR Air Division, introduced, "in recent years, we have been complying with the situation, taking the national industrial policy as the guidance, and through the deep connection with the market, we have found out the 'door' and achieved technological breakthroughs ." It is reported that in the process of technology research and development, DEAR kongfen has gathered the backbone of Enterprise science and technology, cooperated with downstream manufacturers, built simulation test platform, and invested a large amount of money in research and development test. After countless experiments and parameter adjustments, the localization of the energy-saving oxygen generator is finally realized. Compared with the oxygen generator manufactured by traditional craft, the energy-saving oxygen generator developed by DEAR air separation saves about 30% electricity, the oxygen extraction rate increases from 95% to 99%, the investment cost decreases 5%, and the operation is more comfortable and convenient. Take the ordinary 4000-grade air separation plant as an example, the energy-saving oxygen generator can save 1 million yuan only by investing one item.
Meanwhile, the successful research and development of energy-saving air separation nitrogen water precooling system technology has achieved the recovery and utilization of waste heat, which has laid a solid foundation for the future development of domestic air separation precooling technology in the field of energy conservation and environmental protection.
Insiders said that the successful application of two new technologies, energy-saving air separation nitrogen water precooling system and energy-saving oxygen generator, will significantly optimize the structure of air separation industry, it is beneficial for the development of air separation industry to improve quality and efficiency in the direction of energy conservation, environmental protection and comprehensive utilization, and further promote the acceleration of transformation and upgrading of domestic industries such as metallurgy, coal and electricity, coal chemical industry, steel and so on. In addition, as the first national characteristic industrial base in our city -- the National Torch Plan Kaifeng Air separation equipment characteristic industrial base, will also be affected by this, usher in a new round of air separation industry transformation and upgrading revolution, build the advantage of sustainable development.
