摘要： The invention relates to a heat exchanger wherein the heating vapor is fed onto heat exchange surfaces of membrane material from a vapor distributor at their end, the vapor distributor having parallel conduits (3) for directing vapor over the entire width of the surfaces. According to the invention the vapor distributor is made up of two opposite wall elements (1, 7) which are fastened to each other by means of projections (2) in one element and corresponding recesses (6) in the other element. The upper end (9) of the membrane constituting the heat exchange surface is locked between the projections and recesses locked to each other. Thus pleats are produced in the membrane as an expansion leeway for the vapor space delimited by the membrane. The heat exchange surfaces (9) may be formed into bags (10) the ends of which are fastened between the interlinked wall elements (1, 7) in such a manner that the vapor conduits (3) delimited by the elements will direct heating vapor to the inside of the bags and the liquid conduits (11) will direct liquid to be evaporated onto the outer surfaces of the bags.

摘要： The invention relates to a liquid distributor in a evaporator, intended in particular for the evaporation treatment of liquid suspensions which contain fibers or other such solid ingredients. The distributor comprises, located at the upper end of the heat exchange surface, a transverse frame (1), liquid conduits (3, 4) disposed therein distributing the liquid over the entire width of the surface. According to the invention the liquid conduits are made up of feed conduits (3) slanted obliquely downwards and of distrribution conduits (4) branching out therefrom and leading to the heat exchange surface, at the branching points (7) of which conduits their wall surfaces on the downstream side with respect to the feed flow (8) are rounded into curved dividing surfaces (10) by means of which the dividing of the flow is carried out. Respectively the branching points (7) on the upstream side with respect to the feed flow (8) are equipped with sharp feeding tips (11) in such a manner that the flow will travel in the feed conduit (3) in a cascade-like manner over the feeding tips to the dividing surfaces, which will cause a division of the flow substantially equally among the distribution conduits.

摘要： The method relates to a film heat exchanger and a method for constructing the same. The heat exchanger comprises bags (1) made of film material in order to transfer heat from the steam to be condensated inside the bags to the liquid to be evaporated on the outer surfaces (18) thereof, as well as feed channel arrays for distributing steam (10) and liquid onto the internal and external heat transfer surfaces of the bags. According to the invention, inside the top end (2) of each bag (1), there is provided an essentially straight strip (11) bordering the steam channels (10), to which strip the bag is fastened; in connection with the fastening, the top edge of the bag is pulled straight by bending the bag, so that the middle part of the bag is raised in relation to the sides (12) thereof, and the thus straightened edge is then attached to the strip provided inside the bag. Respectively, the bottom edge (3) of the bag can be cut to be upwardly concave and fastened, after straightening, to a strip (15) fitted inside the bottom end of the bag, and comprising condensate removal channels (14). When straightening the top and bottom edges (2, 3) of the bag, there are created horizontal folds (13) in the film material, which folds serve as an inflation margin while pressurizing the bag.
