Abstract
A gas-liquid contact body for use in a gas-liquid contact apparatus is disclosed which is formed of a plurality of facially opposed corrugated sheets with the corrugations in alternate sheets being disposed in parallel to form a plurality of criss-crossing channels for gas and liquid. The contact body has an air inlet side including an air inlet portion which is coated with a water-impermeable hydrophilic material containing an algicide.
Claims7
A gas-liquid contact body for use in a gas-liquid contact apparatus, said contact body comprising a plurality of facially opposed corrugated sheets with the corrugations in alternate sheets being disposed in parallel to form a plurality of criss-crossing channels for gas and liquid, said contact body having an air inlet side including an air inlet edge portion, and an air outlet side including an air outlet edge portion, one or both of said air inlet edge portion and said air outlet edge portion being coated with a water-impermeable hydrophilic material containing a substance having algicide activity which comprises copper or quaternary ammonia salts.
A gas-liquid contact body for use in a gas and liquid contact apparatus having a casing, a gas inlet side and a gas outlet side, said contact body comprising a plurality of corrugated sheets disposed in facially opposed relationship to one another and in substantially parallel relationship to one another and defining a gas inlet edge adapted to be positioned adjacent said gas inlet side of a casing, and further defining a gas outlet edge adapted to be positioned adjacent said gas outlet side of a casing, and a plurality of intersecting and intercommunicating passages allowing the passage of gas and liquid therethrough, the corrugations in each of said sheets extending at an angle to the main section of flow of the gas through the body with the corrugations in alternate strips being disposed at an angle to the corrugations in the adjacent strips, said gas inlet and or outlet edges being coated with a water-impermeable hydrophilic material containing a substance having algicide activity which comprises copper or quaternary ammonia slats.
