Tube bundle equipment with liquid flow regulator elements

Abstract

The present invention relates to Tubebundle equipment of the falling liquid film type, comprising a vertical cylindrical body closed at the ends and divided into at least an upper section(l), an intermediate section(3) and a lower section(2) by means of two perforated tube sheets(15, 106, 206,16) arranged transversally to support the tubes forming the bundle, wherein each of said tubes(4,l 1) is surmounted, on the upper end, by a ferrule (5, 102) , for the inlet and distribution of the liquid in the form of a film,which comprises in the upper part, one or more openings( 103,203) for the outlet of vapours,at an intermediate height one or more openings (204,104), preferably tangential, for the inlet of the liquid and below, a circular base(216) for resting on said tube(4, 111) from which an internal cylindrical section (215), inserted in the tube for a length varying from 1 0 to 2 0 0 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 (214) and said protruding cylindrical section(215), there is a gasket(213), inserted between said circular base(216) of the ferrule(5,102) and said upper edge of the tube.
