INCRUSTATION RESISTIVE CRYSTALLIZER

The crystallizer comprises a housing (15), conduit means (33) for the ingress of solution to be crystallized, and outlet ports (35) and (37) for the removal of product crystals and mother liquor respectively. Perforated plates (21) disposed essentially horizontally and substantially conforming to th...

More Information
Summary:The crystallizer comprises a housing (15), conduit means (33) for the ingress of solution to be crystallized, and outlet ports (35) and (37) for the removal of product crystals and mother liquor respectively. Perforated plates (21) disposed essentially horizontally and substantially conforming to the interior shape of the housing (15) are attached to and vertically spaced along a support member (20). Mobile bodies (25) are disposed on the upper surfaces of the plates (21). Heat transfer tubes (11) provided with conduit means (26) and (28) for the ingress and egress of cooling fluid are located in the housing (15) substantially parallel to the support member (20), and penetrate through apertures in the plates (21). At its upper end, the support member (20) is attached to a compound excitation device (23) adapted to produce two waveforms. The first waveform causes translational movement of the plates (21) for scraping the surfaces of the heat transfer tubes (11). The second waveform causes the plates (21) to vibrate causing the mobile bodies (25) thereon to agitate and collide with each other, with the surfaces of the plates (21) and with the surfaces of the heat transfer tubes (11).
