CRYSTALLIZATION REACTOR

摘要

PURPOSE: A crystallization reactor is provided to discharge chemicals which are crystallized easily, and to perform a stable crystallization process by preventing lamination of crystals on a part adjacent to a drain valve. CONSTITUTION: A crystallization reactor includes the followings: a reaction tank(110) having an internal space in which solidified liquid is stored; a circulation outlet(115) formed on an outer circumference; a circulation inlet(117); a rotary shaft(125) rotated in a reaction bath; an impeller(126,127) fixed on the rotary shaft and agitating solidified liquid; a circulating pipe(140) connecting the circulatory outlet and the circulatory inlet; a drain valve connected with the circulation pipe.
