Abstract
An apparatus for use in an evaporator for selectively controlling the flow of solid particles within the evaporator. The apparatus includes a separation chamber having a plurality of apertures, each of which has a critical size. In the separation chamber, solid particles which are larger than a critical size are separated from the remainder of the solution. The separated particles exit the separation chamber via a bypass conduit for circulation directly to the sump of the evaporator for recombining with the separated liquid portion which passed through the separation chamber and was subsequently concentrated in the heat exchange tubes. The apparatus prevents solid particles from clogging the system and allows for continuous circulation of the solution and solid particles.
