A vapor compression distillation apparatus includes a vessel for containing a liquid to be distilled and a heat exchanger of the shell and tube type immersed in the liquid. The heat exchanger has top and bottom manifolds and vertical tubes surrounded by a shell. Foraminous vortex-drag induction plates extend across the shell between adjacent rows of tubes for inducing turbulence in the vortices to provide a better heat transfer from vapor passing through the shell to liquid in the tubes. Baffles are provided at selected intervals across the shell, between adjacent rows of tubes to produce a sinuous flow path for the heating medium. Steam injecting sparging tubes extend along the lower manifold of the heat exchanger to inject steam bubbles into the liquid to be evaporated. This produces turbulence in the tubes of the heat exchanger, promotes a better flow through the tubes and scrubs the tube interiors.
A heat exchanger of the shell and tube type, comprising first and second manifolds, tubes connecting the manifolds for sassing a first fluid therebetween, and a shell having an inlet and an outlet, said shell surrounding the tubes for confining a flow of a second fluid from the inlet to the outlet for heat exchange with the first fluid, said heat exchanger including sparging means for injecting bubbles of gaseous second fluid into the bottom manifold to pass through the liquid first fluid passing through the tubes.
