<p>We have developed a demonstration machine of a large-capacity air purification system that purifies a large amount of polluted air using a gas-liquid mixing nozzle and a multi-layer metal fiber filter.　A gas-liquid mixing nozzle, driven by the air blower, sucks and accelerates water to form a high-speed two-phase flow. In the centrifugal force field, all the fine particles and aerosols in the bubbles are transferred to the liquid phase water, and the hypochlorite water whose disinfecting effect has been confirmed by the Product Evaluation Technology Infrastructure Organization (NITE). The demo machine can remove fine particles and viruses in the air at 100 m3 per hour with a single nozzle. We have also developed a large-capacity air purification system that can purify 2400 m3 of air per hour with 24 nozzles. In the virus removal evaluation test conducted by The Japan Textile Products Quality and Technology Center (QTEC), the sterilization performance of 99.975% or more was confirmed. We aim to put this technology to practical use at an early stage to purify the air in hospitals, schools, office buildings, etc.</p>
