ELECTROLYSIS APPARATUS WITH SALT WATER CONCENTRATING PROCESS

摘要

The present invention relates to an electrolysis apparatus including a salt water concentrating process. An object of the present invention provides a salt water electrolysis apparatus without performing an anode water regeneration process based on a complex structure by arranging a vacuum evaporation concentrator in a diaphragm seal type electrolysis apparatus so that salt water, which is supplied from an anode water storage tank to an anode chamber, undergoes vacuum concentration and is supplied into an oversaturated salt water or saturated salt water. The present invention includes a diaphragm seal type electrolytic bath that is divided into an anode chamber and a cathode chamber with a diaphragm interposed therebetween so as to electrolyze supplied salt water and soft water; an anode water storage tank in which the saturated salt water that is supplied to the anode chamber of the electrolytic bath is stored; a vacuum evaporation concentrator that produces the oversaturated salt water through the vacuum evaporation concentration of the saturated salt water which is supplied from a salt water supply means or produces the saturated salt water through the vacuum evaporation concentration of the saturated salt water which is supplied from the salt water supply means and low-concentration salt water which reacts in an electrolytic bath anode chamber, and supplies the salt water to the anode water storage tank; and the salt water supply means that supplies the saturated salt water to at least one of the vacuum evaporation concentrator and the anode water storage tank.
