STERILIZING METHOD AND STERILIZER FOR CERTAINLY STERILIZING OR INACTIVATING MICROORGANISM INCLUDED IN GAS OR LIQUID BY GENERATING PULSE STREAMER ELECTRICITY DISCHARGE

摘要

PURPOSE: Provided is a sterilizing method for certainly sterilizing or inactivating a microorganism included in the gas or liquid flowing at high speed, by generating a pulse streamer electricity discharge in the gas nearby both electrodes by applying high voltage in pulse waveform between the electricity discharging electrode and the corresponding electrode. CONSTITUTION: The sterilizing method sterilizes or inactivates an microorganism existing in an electricity discharging area by generating a streamer discharge of electricity nearby both electrodes by applying a high voltage in a pulse waveform between the electricity discharge electrode and a corresponding electrode. The sterilizer comprises an electricity discharging electrode(3), a corresponding electrode(4), and a high voltage application unit for applying the high voltage in a pulse waveform to generate a streamer discharge of electricity. The high voltage application unit is controlled more than once by a frequency to generate the streamer discharge of electricity within the time when the gas or liquid passes an electricity discharging area(5) at a predetermined speed.
