The gas works externally through the expander. In the process of generating cooling capacity, there must be braking to consume this part of work. There are three braking methods: generator braking, fan braking and booster braking. The generator braking can recover the work done by the expander, but the power grid fault will also affect the work of the expander, and the equipment investment is large; The fan braking equipment is simple and easy to operate, but the noise is large, and all the work done by the expander is wasted;; The booster brake absorbs the power of the expander, and at the same time, it can increase the unit cooling capacity of the expander, reduce the expansion air volume, and is conducive to the oxygen extraction rate.
DEAR air separation enterprise intelligent innovation team, in order to improve the core competitiveness of the enterprise, create a scientific and technological enterprise, create a high-quality and energy-saving air separation equipment, and closely follow the development direction of the world manufacturing industry, plans to invest more than 30 million yuan to cooperate with Zhengzhou Kehui technology company, Shenzhen Gugao Motion Control Research Institute, Guyuan special robot company, Shandong Shuibo welding and cutting equipment manufacturing company The Artificial Intelligence Research Institute of Hefei University of technology and other units cooperated with scientific research institutions to create an air separation equipment production line with intelligent flexible production, and a modern intelligent air separation demonstration enterprise integrating intelligent management and operation, remote equipment monitoring and operation.
