FIELD: environmental safety at chemical enterprises. SUBSTANCE: invention may be used for catching hydro/air soles of toxic and corrosive salts, acids, alkalis, and anhydrides from ventilation releases of electrolytic baths and chemical reactors. Filter comprises frame enclosing plate of chemically stable high-porosity cordierite with screen-cellular framework. In dependence on required area of filtering surface, filter may be made in the form of one plate in the frame or a packet of plates installed in lattice-type frame. Filter may be equipped with receiver for collecting condensate of air sole being caught. EFFECT: reduced content of toxic and corrosive substances in ventilation releases to limiting permissive concentrations and reduced corrosive wear of ventilation systems. 2 dwg, 1 tbl |
