No membrane electrolytic device

Abstract

The invention is a no membrane electrolytic device to produce subacid hypochlorous acid water by electrolyzing diluted hydrochloric acid, in which the electrode plates could be cooled by dilution water to produce subacid hypochlorous acid water more effectively.

1 . No membrane electrolytic device to produce subacid hypochlorous acid water, wherein the device comprises a housing ( 22 ) having a sealed inner space, a pair of electrode plates ( 10 ,  10 ′) disposed in the housing ( 22 ) to be opposite to each other, and a partition member ( 12 ) disposed between the electrode plates ( 10 ,  10 ′) to partition the inner space of the housing ( 22 ) into an electrolysis chamber ( 16 ) and a dilution chamber ( 24 ),
 the electrolysis chamber ( 16 ) having a hydrochloric acid inlet ( 18 ) on one side of it into which hydrochloric acid is introduced, 
 the partition member ( 12 ) having passage ( 20 ) which introduces the chlorine gas produced by electrolyzing the hydrochloric acid in the electrolysis chamber ( 16 ) into the dilution chamber ( 24 ), 
 the dilution chamber ( 24 ) having a dilution water inlet ( 26 ) on one side of it to supply dilution water in order to dissolve and dilute the chlorine gas, and a hypochlorous acid water outlet ( 28 ) on the other side of it to exhaust the hypochlorous acid water produced by dissolving the chlorine gas with the dilution water, 
 the electrode plates ( 10 ,  10 ′) further including extending portions ( 10   a,    10   a ′) extending toward the dilution chamber ( 24 ) so that the dilution water ( 24 ) introduced into the dilution chamber ( 24 ) could contact with the extending portions ( 10   a,    10   a ′) of the electrode plates ( 10 ,  10 ′) and cool the electrode plates ( 10 ,  10 ′). 
 
     
     
         2 . No membrane electrolytic device of  claim 1 , wherein the dilution chamber ( 24 ) is disposed above the electrolysis chamber ( 16 ), and the lower surface of the partition member ( 12 ) facing the electrolysis chamber ( 16 ) is formed as an inclined plane ( 20 ) so that the upper part of the electrolysis chamber ( 16 ) becomes narrower as it goes higher, which could introduce the chlorine gas into the passage ( 20 ) more smoothly. 
     
     
         3 . No membrane electrolytic device of  claim 1 , wherein the extending portions ( 10   a,    10   a ′) of the electrode plates ( 10 ,  10 ′) are spaced apart from the inner surface of the housing ( 22 ). 
     
     
         4 . No membrane electrolytic device to produce subacid hypochlorous acid water, wherein the device comprises a housing ( 22 ) having a sealed inner space, a pair of electrode plates ( 10 ,  10 ′) disposed in the housing ( 22 ) and spaced apart from the inner surface of the housing ( 22 ) to be opposite to each other, and a partition member ( 12 ) disposed between the electrode plates ( 10 ,  10 ′) along the periphery of the electrode plates ( 10 ,  10 ′) to partition the inner space of the housing ( 22 ) into an electrolysis chamber ( 16 ) and a dilution chamber ( 24 ),
 the electrolysis chamber ( 16 ) having a hydrochloric acid inlet ( 18 ) on one side of it into which hydrochloric acid is introduced, 
 the partition member ( 12 ) having passage ( 20 ) which introduces the chlorine gas produced by electrolyzing the hydrochloric acid in the electrolysis chamber ( 16 ) into the dilution chamber ( 24 ), 
 the dilution chamber ( 24 ) having a dilution water inlet ( 26 ) on one side of it to supply the dilution water in order to dissolve and dilute the chlorine gas, and a hypochlorous acid water outlet ( 28 ) on the other side of it to exhaust the hypochlorous acid water produced by dissolving the chlorine gas with the dilution water, and 
 the dilution chamber ( 24 ) wrapping up the electrolysis chamber ( 16 ) and the electrode plates ( 10 ,  10 ′). 
 
     
     
         5 . No membrane electrolytic device of  claim 2 , wherein the extending portions ( 10   a,    10   a ′) of the electrode plates ( 10 ,  10 ′) are spaced apart from the inner surface of the housing ( 22 ).
