| 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.
