Definitions

  • Cylindrical electrolysis cells are known for use in the production of diluted Hypochlorous Acid solutions.
  • the basic feature of these cells is two concentrically disposed cylindrical electrodes with a ceramic porous diaphragm separating a space between the two electrodes to define anode and cathode compartments.
  • An electrolyte such as brine is passed through the anode and cathode compartments, separately or successively.
  • brine is electrolyzed in this way, under suitable conditions, it can produce a diluted Hypochlorous Acid solution.
  • porous ceramic diaphragms are not ion specific and therefore at any time when negative ions are attracted to the positive anode and positive ions are attracted to the negative cathode, ions will move without limitations over the ceramic diaphragm.
  • the ceramic diaphragm' s secondary function is to retard the migration of electrolysis products at the anode and cathode from diffusing to each other.
  • the effectiveness of preventing undesired side products moving over the diaphragm depends greatly on a pressure differential between both chambers.
  • the flow of Hypochlorous Acid and Sodium Hydroxide is not equal in volume and pressure, as in most cases more Hypochlorous Acid than Sodium Hydroxide is required. Therefore the volume of Sodium Hydroxide is mostly reduced to a minimum resulting in pressure differences between the anode and cathode chamber which significantly increases leakage of undesired products through the porous ceramic diaphragm.
  • a cylindrical three-chamber cell is described in copending U.S. Patent Publication No. US-2013-0146473 which addresses the undesired migration problem mentioned above, but the absence of any salt residues in the sanitizing solution limits the shelf life and the free-available- chlorine content of the generated Hypochlorous Acid solution.
  • the pH and free-available-chlorine content of these diluted Hypochlorous Acid solutions, both acidic and neutral, generated from these three-chamber cells are less stable, lower in free-chlorine-content and although very suitable for onsite production and usage, it would be unsuitable for bottling and storage.
  • a two cylindrical electrolytic cell device capable of producing various Hypochlorous Acid solutions whereas the pH, redox potential, free chlorine content, conductivity and osmolality can be adjusted.
  • the invention is directed to a cylindrical ion-selective membrane electrolysis cell assembly comprising a cathode chamber and an anode chamber.
  • the present invention provides an insulating end piece for a cylindrical electrolysis cell of the type comprising two cylindrical electrodes arranged coaxially one within the other with one ion-selective membrane arranged coaxially between them.
  • the cylindrical ion-selective exchange membrane is construed from a polymer or a perfluorinated membrane sheet that is stretched, formed and sealed together to form a cylinder that can be leak free assembled in a cylindrical electrolyses cell by mounting the cylindrical ion-exchange membrane between two bushings or by mounting the cylindrical ion-exchange membrane on the inside or around a perforated porous tube.
  • An objective of the invention is to disclose an apparatus and method of improving the stability and shelf life of on-site produced Hypochlorous Acid solutions.
  • Another objective of the invention is to disclose the use of two cylindrical electrolysis cells constructed and arranged to provide a more stable Hypochlorous Acid solution suitable for bottling and storage up to 24 months can be generated.
  • Still another objective of the invention is to disclose how produced Hypochlorous Acid solutions can be used for wound care and hospital sanitation.
  • the Hypochlorous Acid solutions are effective for sanitizing equipment, tools and surfaces, in particular after equipment, tools and surfaces have been cleaned with the generated Sodium Hydroxide solutions.
  • Another objective of the invention is to disclose Hypochlorous Acid and Sodium Hydroxide solutions having a long shelf life and a low salt residue which is in contrast with most generated Hypochlorous Acid and Sodium Hydroxide solutions produced by electrolysis of a brine solution in a single cell utilizing a ceramic diaphragm as separator between the anode and cathode.
  • Still another objective of the invention is to disclose various different sanitizing solutions can be produced utilizing the cylindrical electrolysis cells of the present invention, depending on the various flow patterns through the cells e.g. a neutral Hypochlorous Acid solution with a Ph between 6 to 7.5 and a long shelf life can be generated by dividing the diluted brine solution in a Product-flow (Hypochlorous Acid) and a Waste -flow (Sodium Hydroxide) .
  • a neutral Hypochlorous Acid solution with a Ph between 6 to 7.5 and a long shelf life can be generated by dividing the diluted brine solution in a Product-flow (Hypochlorous Acid) and a Waste -flow (Sodium Hydroxide) .
  • Yet still another objective of the invention is to disclose a diluted Sodium Hydroxide as cleaning solution suitable for cleaning all surfaces, including textiles, fabrics and carpets.
  • Yet another objective of the invention is to disclose a generated cleaning and sanitizing solutions that contains limited salt residues due to the fact that the diluted brine solution passes two of more cells with ion-selective membranes whereas almost all sodium chloride or potassium chloride is efficiently converted into Hypochlorous Acid or Sodium Hydroxide.

Abstract

La présente invention concerne un procédé faisant appel à des cellules cylindriques d'électrolyse pour la production de solutions d'acide hypochloreux (HOCl) présentant d'excellentes propriétés désinfectantes et une durée de conservation de 24 mois lorsqu'elles sont mises en bouteille. Les cellules d'électrolyse sont constituées d'au moins deux électrodes cylindriques dotées d'au moins une membrane cylindrique sélective aux ions disposée de façon coaxiale entre elles. La membrane sélective aux cations ou sélective aux anions sépare la chambre de cathode de la chambre d'anode, en permettant uniquement aux ions sélectifs de passer d'une chambre à une autre. Une pièce terminale à trois sections facilite le montage de la cellule cylindrique d'électrolyse et permet une inspection et un remplacement aisés des membranes sélectives aux ions. Le procédé permet la production de différentes concentrations de solutions d'acide hypochloreux avec une valeur de pH allant de 3,5 à 7,5 et un potentiel d'oxydation redox compris entre +700 et +1200 mV lorsqu'une solution aqueuse de chlorure de sodium ou de chlorure de potassium est traitée.
