A Based on the advanced FCVS technology, such as a gas-liquid mixing nozzle and a multi-layer metal fiber filter, and a silver zeolite filter for the purpose of removing organic iodine. we have developed a demonstration machine for a large-capacity air purification system that purifies a large amount of contaminated air. With this acceleration and centrifugal force field of water, almost all of the fine particles in the bubbles can be transferred to the liquid phase water and dissolved. We have developed a demonstration machine of an air purification system that can remove fine particles and viruses in the air of 100 m3/h with a single nozzle and we also developed a large-capacity air purification system that can purify 2400 m3 of air per hour with 24 nozzles, and results of the paper.
FCVS has succeeded in improving the decontamination factor (DF) of radioactive materials using scrubbing technology. By applying these technologies and making the system robust and compact, and by making it mobile. We expect to be used in a wide range of applications. To realize mobile use, we developed a prototype was manufactured in 2020, and performance tests such as DF tests were conducted in 2021. High DF was confirmed in tests using
