Abstract
PURPOSE: To shorten the time required to concentrate a NaOH soln. with consumption of little electric power by connecting one terminal of the secondary side of a transformer to an electrode in a concentrating drum filled with the soln. and grounded; grounding the other terminal of the transformer; and applying a high electric field without supplying a current to the soln.
CONSTITUTION: NaOH soln. 2 is filled into grounded concentrating drum 1 made of metal, electrode 3 set in the drum is connected to one terminal 6 of secondary side 5 of transformer 4, and other terminal 7 is grounded. A commerical AC power source is then connected to primary side 8 of transformer 4, and a high electric field is applied to soln. 2 in drum 1 heated with constant heat value heater 9. Thus, the concn. effect is increased, and since no current is supplied to the NaOH soln., little electric power about equal to an internal loss of the transformer is consumed.
