Abstract

PURPOSE:To prevent the scale generation in electrolytic bath and to effectively utilize NaOH, by depositing the scale component as solidified matter by adding a surplus part of NaOH to the supply water of cathode room generated more excessive than Cl2 and removing it and moreover, manufacturing NaOCl by using a part of it at the salt electrolysis. CONSTITUTION:Salt water is sent from the anode solution storage tank 4 to the anode room 15 through the line 32 and Cl2 gas is generated and then, is separated in the separator 6 and moreover, is sent to the NaOCl manufacturing apparatus 7 through the line 42. Na<+> generated by the cataphoresis from the room 15 and OH<->, are reacted in the cathode room 14 and NaOH is produced. When produced NaOH is concentrated in a high concentration (>=20%), excess part is sent to the pre- treatment vessel 2 through the line 24 and pH is regulated at >=13.1 and then, Ca(OH)2, Mg(OH)2 are deposited. A part of NaOH solution sent to the room 14 again after deposition and separated H2 gas by the separator 5, is sent to the apparatus 7 through the line 41.
