GAS FLOW CLEANING FILTER Russian patent published in 2013 - IPC B01D53/32 

FIELD: process engineering.

SUBSTANCE: invention relates to gas cleaning and may be used in various industries for separating aerosol particles, including submicron particles condensate components, from flows. Proposed filer comprises precipitation and ionizer electrodes. Ioniser electrode is connected to HV power supply. Precipitation electrode is earthed. Ioniser electrode is electrically insulated and arranged coaxially with clearance relative to precipitation electrode. Filter incorporates extra porous precipitation electrode arranged in offgas jet from precipitation electrode. Proposed filter features good few extra characteristics to up its performances. Invention allows using cleaned gas flow power in approach of said flow to extra precipitation electrode and displacement over extra precipitation electrode pores. In displacement of cleaned gas flow over extra precipitation electrode pores, charged drops and aerosol particles are caught by earthed surface of said extra electrode while clean gas is expelled by jet power outward.

EFFECT: smaller sizes of filter used for automotive exhaust gas cleaning.
