ABSTRACT:
Apparatus is provided for securing a fabricated diaphragm to each of a section of electrodes. A diaphragm encloses each electrode and has an open end adjacent to the electrode plate. The apparatus comprises two bars, one positioned along a first side and one positioned along a third side of the electrode section. A plurality of elements are attached to each of the bars. The elements are positioned between adjacent electrodes and secure one edge of each of two adjacent diaphragms. The elements may be interconnected to provide additional sealing of the diaphragm. A rod is positioned along the second and fourth sides of the electrode section to seal the outer edge of the diaphragm enclosing the external electrodes of the section.
The apparatus is employed in electrolytic diaphragm cells for producing chlorine and caustic soda by the electrolysis of alkali metal chloride solutions.
A method is provided for employing the apparatus to effectively seal the diaphragm to the electrode section.
