Dual Diaphragm Electrolysis cell assembly and method for generating a cleaning solution without any salt residues and simultaneously generating a sanitizing solution having a predetermined level of available free chlorine and PH

Abstract

An electrolysis cell assembly to produce diluted Sodium Hydroxide solutions NaOH and diluted Hypochlorous Acid HOCl solutions having cleaning and sanitizing properties. The electrolysis cell consists of two insulating end pieces for a cylindrical electrolysis cell comprising at least two cylindrical electrodes with two cylindrical ion selective membranes arranged co-axially between them. The method of producing different volumes and concentrations of diluted NaOH solutions and diluted HOCl solutions comprises recirculating an aqueous sodium chloride or potassium chloride solution into the middle chamber of the cylindrical electrolytic cell and feeding softened filtered water into the cathode chamber and into the anode chamber of the cylindrical electrolysis cell.

Description

PRIORITY CLAIM[0001]In accordance with 37 C.F.R. 1.76, a claim of priority is included in an Application Data Sheet filed concurrently herewith.

AI Technical Summary

Benefits of technology

The invention is about improving an electrolytic cell design to produce effective cleaning and sanitizing agents. It involves a cylindrical electrolysis cell assembly with two coaxially mounted ion-exchange membrane tubes creating a middle chamber for circulation of electrolyte. The construction and assembly of an easy-to- replace ion-exchange membrane tube in a sturdy dimensionally stable manner is also important. The factors that affect the production of cleaning and sanitizing agents include the construction, assembly, and fluid velocity of the electrolytic cell. The objective of the invention is to provide a stable and effective design for producing cleaning and sanitizing agents while ensuring constant quality.

Problems solved by technology

When the two-chamber cylindrical cell depicted in FIG. 1 is used, the cathode water is not necessarily suitable for actual cleaning or a surface treatment without rinsing the surface with distilled, RO or tap water.

The anode water is not necessarily suitable for sanitizing hard surfaces without rinsing the surface afterwards with distilled, RO or tap water.
