Date Oct. 6, 1988.Apparatus (10) for the evaporation of liquids or for the absorption or degassing of two-substance or multi-substance solutions of the interior tube falling film type of construction, with a pressure tank (12) through which a heat exchanging medium can pass, whose interior contains a plurality of vertical parallel tubes (22) set apart from one another which open in a bell (26; 24) placed on the bottom and on the top of the pressure tank, the upper ends of the tubes projecting above the upper side of the top place of the pressure tank. On the upper bell (24) there is provided an inlet (36) for the liquid or solution, and a connection (38) for the input or output of evaporated liquid or gaseous solution component, and on the bottom bell there is provided an outlet (34) for liquid or liquid solution. At a distance above the mouths of the tubes (22) a dividing plate (42) is inserted into the bell, which has a plurality of bores (44) of small diameter. At a distance above this dividing plate (42) an additional dividing plate is inserted into the bell (24) and the interstice formed between the two dividing plates and connected to the inlet (36) for the liquid or liquid solution component is filled with a number of vertical tubes (54) carried through perforations in the dividing plates, the said vertical tubes being aligned with the mouths of the tubes (22) passing through the pressure tank.</p> |
