ELECTRIC FILTER Russian patent published in 2010 - IPC B03C3/06 

FIELD: mechanics.

SUBSTANCE: proposed electric filter comprises cylindrical housing, precipitation corona-forming electrodes, ultrasound oscillation generator and dust collecting bin. Purified gas discharge housing is made from isolating material. Precipitation electrodes are made from metal screen, corona-forming electrodes are made from a set of metal arc-like plates furnished with corona-forming needles arranged on their both sides. Corona-forming and precipitation electrodes are fitted in the housing layer by layer. Ultrasound oscillation generator is arranged level with top part of precipitation and corona-forming electrodes and jointed therewith with the help of metal hose.

EFFECT: higher quality and rate, increased concentration of light negative aeroions in inside air, higher quality of dust removal from electrodes.
