DEVICE FOR CLEANING AIR FROM DUST AND AEROSOLS Russian patent published in 2003 - IPC

FIELD: electrostatic precipitators for cleaning air from dust and aerosols. SUBSTANCE: proposed device has housing with air passages with receiving and corona-forming electrodes arranged inside it and unit for aromatic agents and drugs. Device is additionally provided with positively charged aeroion damper which is electrically connected with corona-forming electrodes ensuring their grounding; device is also provided with regulator of number of negatively charged aeroions which is electrically connected with deflecting electrode. Mounted directly on plate of one of deflecting electrodes is radiator of negatively charged aeroions whose potential changes by means of said regulator. Plates of deflecting electrodes have negative charge. EFFECT: avoidance of toxic emissions; possibility of performing proportioned saturation of purified air by negatively charged aeroions. 1 dwg
