Improvement of particle clean air delivery rate of an ion spray electrostatic air cleaner with zero-ozone based on diffusion charging

摘要: Abstract A novel electrostatic precipitation type air cleaner with ion spray to indoor for diffusion charging was developed. To minimize unexpected collection of charged particles on wall or residents and apply the ESP real environment, clean delivery rate enhanced by increasing flow rate, area at applied high voltages -5 kV while its noise ozone emission were evaluated. For practical usage, CADR in environment 83.5 m3 evaluated, recovery tests after contamination dusts cleaning performed. The experimental results show that increase 10 m3/min 4 m2, particle 0.3-μm advanced increased 7.32 m3/min which meant became faster approximate 8.5 times than our previous study, 90% submicron collected within 16 min emitting negligible 1.3 ppb 12 h. In (83.50 m2), CADRs maintained 15% decrease, compared those chamber test. Finally, performance reduced over long-term operation, but almost recovered through processes. It is concluded can be a proto frequent circulation it could promising method without quality against fine particles.
