Abstract
An evaporator having a vertically mounted elongated tubular chamber, a pair of upper and lower tube sheets mounted near the ends of said tubular chamber, each tube sheet having a plurality of openings therein with a plurality of vertical evaporator tubes mounted between the pair of tube sheets, tangentially mounted inlet tubes between the upper tube sheet and a top cover for the tubular chamber, and an inverted cone mounted as a filler piece on the underside of the top cover and having its apex just slightly spaced from the upper tube sheet and its circumferential edge substantially spaced therefrom for effecting a uniform and even flow and distribution to the evaporator tubes of a liquid/solid mixture inputted into the tangential inlet tubes. The elongated tubular chamber is also provided with lateral inlet and outlet openings for inputting/outputting heated and subsequently cooled fluid to flow externally past the evaporator tubes. An opening at the bottom of the chamber is provided for egress of the dehydrated solids, as in the case of an aqueous solids feed material, which emerge after passage through the evaporator tubes. Usage of the whole apparatus as a chiller or cooler and condenser is considered, too.
