Patent ID: 8206494

Claim:
A device for air/water extraction by semi-wet electrostatic collection, comprising: a chamber ( 7 ) comprising a discharge electrode ( 1 ) for creating a stream of ions from an ionized pocket of gas surrounding the discharge electrode ( 1 ) and a counter-electrode ( 2 ), an inlet ( 3 ) for the air and aerosol mixture to be extracted which comprises liquid or solid particles, a vapor delivery tube ( 8 ) and an outlet ( 4 ) for the cleaned air, wherein said device is adapted to introduce vapor via said vapor delivery tube ( 8 ) into a space between the discharge electrode ( 1 ) and the counterelectrode ( 2 ) so as to form a sheathing of vapor ( 10 ) surrounding the discharge electrode ( 1 ) over its entire length, so that all the air treated is not saturated in vapor and wherein said device additionally comprises collecting means using capillary action , gravity or shearing with air.
