　Ten years of rapid development in chemical engineering technology – praising the prosperity and strength of modern China. This is just a starting point; more participation will make things even more interesting. HAICHUAN becomes even better with you here. [Ten years of development in chemical engineering equipment] – continuous updates and summaries available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html. Enhance quality awareness and promote high-quality development. ----------------------------------------- On August 29, 2023, the Zhejiang Machinery Industry Federation organized an evaluation meeting for the scientific and technological achievements related to the “Support-type Sliding Radial Flow Purification Device” developed by this company. The appraisal committee unanimously agreed that the overall technical level of this achievement is at the international leading level, and approved its appraisal. 　　The purification unit uses physical adsorption to remove low-boiling-point impurities such as carbon dioxide, acetylene, and water from the air, and it is an extremely important component in major systems such as cryogenic air separation or air liquefaction for energy storage. 　　This project conducted research on the key technologies related to support-type sliding radial flow purification devices. It invented a multi-layer bed radial flow adsorber capable of large-scale expansion and contraction, and developed a novel design technique for micro-stress structures in the internal components, enabling the internal grids to expand and contract freely during operation while keeping the stress on the multi-layer grids at near-zero levels, thereby improving the reliability of the equipment ； A long-cycle operation technology for the supported sliding-type radial flow adsorber was developed, which extended the service life of the purification system, increased the yield of air separation products, and reduced operational energy consumption ； The challenge of adaptive control for air quality in the purification system using radial flow adsorbers has been overcome; this enables the operation of the purification system to be automatically adjusted based on changes in parameters such as CO2 levels and temperature in the atmosphere, thereby enhancing the reliability and stability of the system. The project-related technologies have yielded 5 invention patents and 10 utility model patents, including 1 patent in Germany and 1 patent in France. This project differs from any other radial-flow adsorption purification device in the world; it solves international-level challenges. This device can be applied to all air separation units, thereby enhancing the international competitiveness of China’s air separation equipment and promoting the innovative development of major domestic equipment.
