Abstract
An electrolytic cell capable of controlling the pH and the ORP independently to each other, comprising an electrolytic chamber (113) to which subject water to be electrolyzed are supplied, membranes (115, 115) provided on the both side walls of the electrolytic chamber, a pair of electrode plates (116, 117) respectively provided inside the electrolyzed chamber and outside the electrolytic chamber sandwiching the membrane therebetween, and wherein the electrode plate (116) is provided outside the electrolytic chamber in contact with the membrane (115) or leaving a slight space.
Claims10
An electrolytic cell, comprising:
- an electrolytic chamber to which subject water is supplied, and at least a pair of electrode plates having a first electrode plate and a second electrode plate;
- said first electrode plate provided inside said electrolytic chamber;
- and said second electrode plate provided outside said electrolytic chamber;
- a membrane sandwiched between said first electrode plate and said second electrode plate;
- and said electrolytic cell,
- wherein said second electrode plate located outside said electrolytic chamber is provided in contact with the membrane or leaving a slight space.
An electrolytic cell comprising:
- a first electrolytic cell having a first electrolytic, chamber and a second electrolytic chamber adapted to be filled by subject water and separated by a membrane and at least a pair of electrode plates sandwiching the membrane therebetween respectively provided in said first electrolytic chamber and said second electrolytic chamber;
- a second electrolytic cell having a third electrolytic chamber to which electrolyzed water produced in said first electrolytic chamber of said first electrolytic cell is supplied, at least a pair of electrode plates sandwiching a membrane therebetween respectively provided inside of said third electrolytic chamber and outside of said third electrolytic chamber;
- and said electrolytic cell wherein said electrode plate outside of said third electrolytic chamber is provided in contact with said membrane or leaving a slight space.
A descaling method of an electrolytic cell comprising an electrolytic chamber to which subject water is supplied and at least two pairs of electrode plates, each pair of electrode plates having a first electrode plate provided inside of said electrolytic chamber and a second electrode plate provided outside of said electrolytic chamber;
- a membrane being sandwiched between said first electrode plate and said second electrode plate, said method comprising the steps of:
- a first reverse descaling step for carrying out by applying a voltage of either one of an anode or a cathode to one of said electrode plates provided inside said electrolytic chamber, and simultaneously applying a voltage of the other one of the anode or the cathode to the other one of said electrode plates, and
- a second reverse descaling step for carrying out by reversing the polarity of the applying voltage to said electrode plates.
