摘 要：
PURPOSE:To increase total quantity of heat in a refining tower by returning
cooled crystals from one or more than two points into the refining tower after
collecting part of refined crystals taken out of the refining tower.
CONSTITUTION:A solid-liquid separating plate 4 is installed at the bottom of a refining tower 1, and a liquid discharge outlet 5' and a raw material crystal supply port 6 are installed below and above the separating plate 4' respectively. Also, a refined crystal outlet port 8 is installed at the upper section of the refining tower 1 and heating means 7 are provided in multi-stage along the longitudinal
direction of the tower inside the refining tower 1. After part of refining crystals is taken out of the refining tower 1, said collected crystals are returned from one or more than two points into the refining tower 1, by which total quantity of heat, or refining operation, can be enhanced maintaining filled state of crystals in the refining tower 1.
