抄録

<p>A gas-liquid mixing nozzle and a multi-layer metal fiber filter are used, and a silver zeolite filter is installed for the purpose of removing organic iodine. Based on this technology, we have developed a demonstration machine for a large-capacity air purification system that purifies a large amount of contaminated air. A gas-liquid mixing nozzle driven by air blown from a blower sucks and accelerates water to form a high-speed two-phase flow. 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. Next, we also developed a large-capacity air purification system that can purify 2400 m3 of air per hour with 24 nozzles. The FCVS system, which is high-performance and passively activated, is thought to help eliminate obvious infringement of personality rights, avoid litigation outages, and promote public acceptance for nuclear power.</p>
