METHOD FOR PROCESSING EXHAUST FILTERS BASED ON FABRIC Petryanov

摘要

1. A method of treating exhaust filters based Petryanov tissue comprising contacting them with an organic liquid, dissolving the filter material, the separation of airborne particles accumulated on the filter from the resulting solution Petryanov tissue deposition of filter material with its subsequent separation from the regeneration solution and rastvoritelya.2 . A method according to claim 1, characterized in that the filter of accumulated solid aerosol contains substances that are returned to the manufacturing or other oborot.3. A method according to claim 1, characterized in that as organic liquids that dissolve the filter material, preferably a butyl cellosolve, methylene chloride, ksiloly.4. A method according to claim 1, characterized in that as a precipitant liquid filter material used indefinitely miscible with the solvent and does not dissolve the filter material, preferably water, alcohols, saturated uglevodorody.5. A method according to claim 1, characterized in that the regeneration of the solvent is carried out by distillation under reduced pressure.
