The invention concerns a device for purifying a gas stream containing condensable vapours. The device comprises a shell (b 7) defining a sealed volume, a cooler for quenching the gas stream, a rotating assembly ( 42 ) including a rotor ( 44 ) and a cylindrical separating and filtering ferrule ( 54 ) consisting of two circular slotted bands ( 56 ) mounted on the rotor and rotating therewith; a supporting tube ( 48 ) mounted on the rotor ( 44 ) and bearing a swirling-scraper device ( 50 ), a cylindrical electrode ( 94 ) surrounding the separating and filtering ferrule ( 54 ) and a central counter-electrode ( 94 ) for creating an electrostatic field in the shell ( 7 ), an outlet duct for the purified gas, an outlet duct for the condensates ( 40 ). Impact and separation plates ( 64 ) are fixed on the bands of the collet. Device for purification of a gas flow containing condensable vapours. The device comprises a shell ( 7 ) defining a sealed volume, a cooler to quench the gas flow, a rotating assembly ( 42 ) comprising a rotor ( 44 ) and a cylindrical separation and filtration skirt ( 54 ) composed of serrated circular rings ( 56 ) mounted on the rotor and rotating with it; a support tube ( 48 ) mounted on the rotor ( 44 ) and carrying a turbulator-scraper device ( 50 ), a cylindrical electrode ( 94 ) surrounding the separation and filtration skirt ( 54 ) and a central counter-electrode ( 7 ) to create an electrostatic field in the shell ( 7 ), a purified gas. outlet tube , a condensates outlet pipe ( 40 ). Impact and separation plates ( 64 ) are fixed on the rings of the skirt.
