Sodium hypochlorite manufacturing electrolytic cell

Abstract

The present invention relates to an electrolytic cell for producing sodium hypochlorite by electrolyzing salt water such as salt water or seawater. The horizontal type non-diaphragm electrolyzer related to the new structure is described in more detail as follows: the internal space of the hollow shell is divided into a plurality of electrode chambers by a separator, and there is a certain interval inside the quadrangular space penetrating the above separator. Arranged electrode plates and fixing rods for fixing the above-mentioned separating plate to the inner wall of the shell. There is no need for welding or pasting means inside the above-mentioned shell, and the above-mentioned electrode plates can also be kept at a certain interval.

Description

technical field [0001] The present invention relates to an electrolytic cell for producing sodium hypochlorite by electrolyzing salt water such as salt water or seawater. The electrolytic cell related to the new structure is described in more detail as follows: the internal space of the hollow shell is divided into a plurality of electrode chambers by the separator, the electrode plates arranged at certain intervals in the quadrangular space penetrating the above separator, the The above-mentioned separation plate is fixed to the fixed rod on the inner wall of the shell. There is no need for welding or sticking means inside the above-mentioned shell, and the above-mentioned electrode plates can also be kept at a certain interval. Background technique [0002] Sodium hypochlorite (NaOCl; Sodium Hypochlorite) is a colorless or light greenish-yellow liquid, which has strong disinfection, deodorization and bleaching effects and high safety, so it is widely used in cleaning food ...

AI Technical Summary

Problems solved by technology

[0008] But in the above figure 2 structure of the electrolytic cell 9, because brine and sodium hypochlorite will move to each electrode chamber 5 through the flow channels 8 formed up and down inside the above-mentioned separator plate 4, there is a problem that the flow of brine is not smooth, especially for fixing the above-mentioned electrode plate 3 or separator plate 4, Need to stick or weld and bring some troubles

Furthermore, if the components are joined by welding or pasting inside the housing 2, the metallic substances or chemical components used will become factors that hinder the electrolytic reaction to salt water, and corrosion or electric leakage will often occur at the above-mentioned joints, resulting in reduced durability.
