PCT No. PCT/FI95/00524 Sec. 371 Date May 29, 1997 Sec. 102(e) Date May 29, 1997 PCT Filed Sep. 26, 1995 PCT Pub. No. WO96/09872 PCT Pub. Date Apr. 4, 1996A liquid distributor in an 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, liquid conduits disposed therein distributing the liquid over the entire width of the heat exchange surface. According to the invention the liquid conduits are made up of feed conduits slanted obliquely downwards and of distribution conduits branching out therefrom and leading to the heat exchange surface. At the branching points of the conduits their wall surfaces on the downstream side with respect to the feed flow are rounded into curved dividing surfaces by means of which the dividing of the flow is carried out. Respectively the branching points on the upstream side with respect to the feed flow are equipped with sharp feeding tips in such a manner that the flow will travel in the feed conduit 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. |
