Ozone producing system

Abstract

In an ozone producing electrolytic cell for producing ozone gas by water electrolysis, said anode compartment 1 , said cathode compartment 2 , said anode compartment frame 6 , said anode 8 , said ion exchange membrane 9 , said cathode 10 , said current collector 11 , and said cathode compartment frame 12 constituting the electrolytic cell for ozone production 3 are all in the same shape of square or rectangular; and multiple numbers of grooves 13 are formed on the internal surfaces of said anode compartment frame 6 and said cathode compartment frame 12 , thereby reducing current density to suppress load on the electrolytic cell for ozone production, even under a given current value supplied to the electrolytic cells for producing ozone.

1 . An ozone producing system, comprising a perfluorocarbon polymer ion exchange membrane ( 9 ), an anode ( 8 ) supported with ozone generation catalyst on an electrically conductive porous material and a cathode ( 10 ) supported with platinum catalyst tightly installed on each side of said ion exchange membrane ( 9 ), an anode compartment frame ( 6 ) installed on the back of said anode ( 8 ), an anode compartment ( 1 ) formed between the internal surface of said anode compartment frame ( 6 ) and the back of said anode ( 8 ), a cathode compartment frame ( 12 ) installed on the back of said cathode ( 10 ) via a current collector ( 11 ), and a cathode compartment ( 2 ) formed between the internal surface of said cathode compartment frame ( 12 ) and the back of said current collector ( 11 ), characterized in that in an electrolytic cell for ozone production ( 3 ) for producing ozone gas from pure water supplied to said anode compartment ( 1 ), said anode compartment ( 1 ), said cathode compartment ( 2 ), said anode compartment frame ( 6 ), said anode ( 8 ), said ion exchange membrane ( 9 ), said cathode ( 10 ), said current collector ( 11 ), and said cathode compartment frame ( 12 ) constituting said electrolytic cell for ozone production ( 3 ) are all in the same shape of square or rectangular; and multiple numbers of grooves ( 13 ) are formed on the internal surfaces of said anode compartment frame ( 6 ) and said cathode compartment frame ( 12 ).  
   
   
       2 . An ozone producing system according to  claim 1 , wherein cooling jackets ( 16 ,  16 ) are installed to attach tightly to the external surfaces of said anode compartment frame ( 6 ) and said cathode compartment frame ( 12 ).  
   
   
       3 . An ozone producing system according to claims  1  and  2 , wherein an anolyte gas-liquid separation tower ( 4 ) to separate anolyte from ozone-containing gas generated in said anode compartment ( 1 ), being connected to said anode compartment ( 1 ) and a catholyte gas-liquid separation tower ( 5 ) to separate catholyte from hydrogen gas generated in said cathode compartment ( 2 ), being connected to said cathode compartment ( 2 ) are installed outside of said electrolytic cell for ozone production ( 3 ).
