Abstract
A liquid distributor for distributing liquid over the heat transfer surface of an evaporator includes a channel array including one or more supply channels and downwardly deviating distribution channels. Each distribution channel has a step-shaped expansion located downstream with respect to the supply channel and connecting therewith via a sharp point, restricting the liquid suction created in the distribution channel. Sharp points provided in the supply channel or channels further restrict the liquid suction.
Claims10
A liquid distributor for use with a film evaporator to distribute liquid suspensions containing solids, comprising a channel array (3, 4), provided at the top of a liquid-evaporating heat transfer surface (5), for distributing liquid (8) fed in at the side of the evaporator over the whole width of the surface, said channel away including at least one transversal supply channel (3) and a number of downwardly deviating distribution channels (4) leading to the heat transfer surface, and a step-shaped expansion (14) in each distribution channel 4 connected via a sharp point (15) to the downstream-side of the supply channel, with respect to the flow (8, 11) of the supply channel, for restricting the liquid suction created in the distribution channel.
