VERTICAL TUBULAR ELECTRIC FILTER (VERSIONS) Russian patent published in 2017 - IPC B03C3/06 B01D35/06 B01D46/00 

FIELD: technological processes; gas industry.

SUBSTANCE: invention relates to electric cleaning of gases from suspended particles in different industries, in particular, in chemical and petrochemical industry, metallurgy and other industries. Vertical tubular electric filter comprises a housing, precipitation electrodes, corona-forming electrodes, power supply, characterised by that it comprises an electric drive, rigidly coupled with mechanical transmission, which in its turn is connected to precipitation electrodes arranged in form of hollow drums, configured to rotate on horizontal axles in insulators and bearings, wherein axles are hollow having inside them high-voltage wires, some ends of which are fixed on inner side of precipitation electrodes, and other ends are attached to contact rings fitted on axis of precipitation electrodes, having a sliding contact with brush assemblies mounted on housing and connected by high-voltage wires to power supply, which is also connected with corona-forming electrodes, fixed in insulation inserts, which are fixed in housing of vertical tubular filter in lower part of which there is a catalyst, and at ends of housing there are discharge sleeves to secure scrapers are attached, wherein sleeves are connected with dust collector bin. In vertical tubular electric filter according to second version, precipitation electrodes are made in form of hollow drums and are configured for rotation on vertical axes in insulators and bearings fitted in horizontal inserts of housing, wherein number of precipitation and corona-forming electrodes, as well as their diameters are selected, based on need to ensure required cleaning of gases of combustion products.

EFFECT: technical result is providing permanently clean surface of precipitation electrode in active zone of electric filter, which provides higher efficiency of electric filter due to exclusion of ash dust, repeated sticking settled dust when cleaning of precipitation electrodes and elimination of intermittent nature of voltage supply to precipitation and corona-forming electrodes.
