FILTER Russian patent published in 1996 - IPC

FIELD: chemical, petrochemical industries, liquids clearance from organic, mineral and other impurities. SUBSTANCE: filter has hermetically joined to each other lid 21 with hole and mounted in it insulated electrode 22, body 1, inside which filtering section 2 is mounted, that has central perforated pipe 3, around which made of electrically conductive material, for example, fiber carbon material, filtering member 4 is wound. Tightening member is made of metal net 5, that is made of open cylinder with capability of its ends joining. Filtering member 5 is located inside net 5. Inside perforated pipe 3 central branch pipe 10 is mounted, that is linked to flange 11 and supporting flange 13, on which body 1 is mounted. Flange 13 has hole, in which electrode 23 is mounted. Electrode 23 is through central branch pipe 10 electrically connected to central perforated pipe 3. Connected with net 5 electrode 22 is mounted in lid 21 hole. Due to the fact, that net is made open with capability of its ends joining, filtering material tightening is exercised. Potentials difference between electrodes provides filtering material heating, that causes burning of pollution organic substances and their withdrawal from filter body by inert gasses. EFFECT: improved purification. 1 dwg
