Integrated electrostatic collection and microwave sterilization for bioaerosol air purification

摘要

Air cleansing apparatus includes an electrostatic precipitator in which the collector plates are made of, for instance, reticulated chemical vapor deposited silicon carbide, or reticulated silicon carbide ceramic coated with titanium nitride, zirconium diboride, or chemical vapor deposited silicon carbide. Microorganisms entrained on the collector plates are thermally degraded or vaporized by microwave radiation directed against the plates during a sterilization period which follows a collection period.
