PROCESS OF PURIFICATION OF AIR FROM IMPURITIES Russian patent published in 1999 - IPC

FIELD: electric purification of air from impurities. SUBSTANCE: before purification impurities placed into inhomogeneous electric field created by deposition electrode connected to high-voltage source are polarized in agreement with given process of purification. Then polarized impurities are attracted by inhomogeneous electric field to deposition electrode. After deposition of impurities on electrode nonpolarized impurities from polluted ambient air are transferred by diffusion to deposition electrode with creation of gradient of partial pressures of impurities in air that surrounds deposition electrode. EFFECT: prevention of ionization of air or reduction of it, decreased consumption of electric energy. 1 dwg
