Claim:
An electrolytic cell for producing sodium hypochlorite, comprising; a hollow housing ( 10 ) having an inner space extended in its longitudinal direction; a brine supply hole ( 11 ) installed at a lower end portion of one side of the housing; a brine discharge hole ( 12 ) installed at an upper end portion of the other side of the housing; a plurality of separators ( 20 ) tightly coupled to an inner wall of the housing ( 10 ) and dividing an inner space of the housing ( 10 ) into multiple electrode chambers (C); a cut portion ( 21 ) positioned at an upper end portion of each of the plurality of separators, forming a hydrogen discharge path (P) between the inner wall of the housing and the cut portion ( 21 ), and further forming a rectangular space (S) penetrating through a central portion of each of the plurality of separators; a plurality of electrode plate insertion grooves ( 22 ) formed in a regular interval at an upper side and a lower side of the space (S); a plurality of fixation bar insertion grooves ( 23 ) formed on edge portions of each of the plurality of separators which are tightly coupled to the inner wall of the housing ( 10 ); a plurality of electrode plates ( 30 ) that are arranged side by side inside the electrode chambers (C) such that the regular interval between each electrode plate is maintained by each electrode plate being vertically inserted into corresponding upper and lower electrode plate insertion grooves ( 22 ) formed at the plurality of separators ( 20 ); and a plurality of separator fixation bars ( 40 ) with a plurality of separator fixation grooves ( 41 ) formed at positions where the plurality of separators ( 20 ) are installed, wherein the plurality of separator fixation bars are inserted into the plurality of fixation bar insertion grooves ( 23 ) of the plurality of separators ( 20 ) to fixate the plurality of separators ( 20 ) at the inner wall of the housing ( 10 ) wherein the plurality of separators comprise type A separators ( 20 a ) with narrow electrode plate insertion grooves ( 22 a ) and type B separators ( 20 b ) with wide electrode plate insertion grooves ( 22 b ), wherein the spacing between the electroplate insertion grooves ( 22 a ) of the type A separator ( 20 a ) is half the spacing between the electroplate insertion grooves ( 22 b ) of the Type B separator ( 20 b ), such that two electrode plate insertion grooves ( 22 a ) of the type A separator ( 20 a ) overlap one electrode plate insertion groove ( 22 b ) of the type B separator ( 20 b ); and electrode plates cut to a specific length are alternately inserted into the electrode plate insertion grooves of the type A and type B separators such that anodes and cathodes intersect.
