ELECTRICAL AIR CLEANER Russian patent published in 2000 - IPC

FIELD: air cleaning system. SUBSTANCE: the electrical air cleaner has at least one electrode group installed in the air conduit and having corona-forming and precipitation electrodes of opposite polarities. The deflecting electrode is installed near the precipitation electrode and has an opposite polarity. In addition the electrode group has the first passive electrode installed before the corona-forming electrode preventing the passage of positively charged aerons through it into the atmosphere, the second passive electrode installed past the deflecting electrode preventing the passive of positively and negatively charged aerons through it into the atmosphere, and the third electrode serving as a source of negative aerons, electrically coupled to the precipitation electrode and installed past the second passive electrode. EFFECT: enhanced degree of air cleaning due to production of negatively charged aerons in cleaned air useful for human- being. 2 dwg
