Tube-bundle equipment of the falling liquid film type, comprising a vertical cylindrical body closed at the ends and divided into at least an upper section, an intermediate section and a lower section by means of two perforated tube sheets arranged transversally to support the tubes forming the bundle, wherein each of said tubes is surmounted, on the upper end, by a ferrule, for the inlet and distribution of the liquid in the form of a film, which comprises in the upper part, one or more openings for the outlet of vapors, at an intermediate height one or more openings, preferably tangential, for the inlet of the liquid and below, a circular base for resting on said tube from which an internal cylindrical section, inserted in the tube for a length varying from 10 to 200 mm, protrudes downwards together with an outer metallic strip for a length of at least 2 mm, so that, in the circular area defined between said outer metallic strip and said protruding cylindrical section, there is a gasket, inserted between said circular base of the ferrule and said upper edge of the tube.
Tube-bundle equipment of the falling liquid film type, suitable for thermal exchange between fluids, comprising a vertical cylindrical body closed at the ends and divided into at least one upper section, an intermediate section and a lower section by means of two perforated tube sheets arranged transversally at a suitable distance from each other, wherein a plurality of tubes are arranged longitudinally forming a tube-bundle and seal-inserted with the respective ends in the holes of said tube sheets allowing said upper section and lower section of the cylindrical body to be in fluid communication with each other, each tube being surmounted, on the upper end, by a tubular device, also called ferrule, for the inlet and distribution of the liquid in the form of a film along the wall of the same, said tubular device comprising above one or more openings for the outlet of vapours, at an intermediate height one or more openings, for the inlet of the liquid and below, a circular base for holding on the upper end of said tube and a lower cylindrical section protruding downwards beyond the circular base, inserted in said tube for a length varying from 10 to 200 mm, characterized in that said ferrule comprises a further metallic strip arranged laterally with respect to the outside of said circular base and protruding beyond this for a length of at least 2 mm downwards, and in that, in the circular area defined between said outer metallic strip and said cylindrical section protruding downwards, there is a gasket, inserted between said circular base of the ferrule and said upper end of the tube;
