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.

- the present invention is directed to method of producing a stable Hypochlorous Acid solution suitable for bottling and storage utilizing two optimized cylindrical electrolysis cells having two cation-exchange membranes as separator between the anode and cathode or a cation- exchange membrane and a anion-exchange membrane as separator between the anode and cathode.
- Tube cap [4] seals the outer electrode [3] with the end piece using an O-ring [8] .
- the tube cap [4] is locked on the outer electrode [3] using a stainless steel clip [11] .
- the outer electrode tube-ends facilitate a groove [12] that fits the stainless steel clip [11] which is pushed through two holes formed in the tube cap [4] .
- Port B cap [5] features port B for direction of the flow of a diluted brine solution through port B ending in fittings [17] into the chamber B defined by the spaces between the outer electrode [3] and the cylindrical ion- selective exchange membrane [2] and out of chamber B through port B ending in fittings [17] of the opposite port B cap [5] .
- Port A cap [6] features port A for direction of the flow of a diluted brine solution through port A ending in fittings [17] into chamber B defined by the spaces between the inner electrode [1] and the cylindrical ion-selective exchange membrane [2] and out of chamber A through port A ending in fittings [17] of the opposite port A cap [6] .
- the three sections of end piece are compressed on each other using 0-rings [7] to seal the sections on each other.
- Either of the electrodes [1] and [3] can act as the anode with the other acting as the cathode.
- the choice can be made by considerations of the ease of manufacture or requirements of the nature of the electrolysis process to be performed which can favor the anode or cathode chamber preferentially being the outer chamber. These considerations include the desired spacing between the electrodes and the diaphragms, the desired space between the cylindrical ion-selective exchange membrane [2] and the relative volume requirements for the balance of flows of the electrolyte solution in chamber A and chamber B.
- the outer electrode [3] has an electrical connector [15] welded to the outside of the outer electrode [3] tube.
- the inner electrode [1] has an electrical connector [16] on its end that is part of the inner electrode [1] and extends out of the outside of the upper end piece.
- the outside of the outer electrode [3] is insulated by a rubber sleeve [14] that is heat-shrinked over the outer electrode [3] and cut to length.
- an insulating sheath or tube can be glues to the outside of the outer electrode [3] .
- the anode and cathode are separated by a cylindrical ion-selective exchange membrane [2] .
- the cylindrical ion- exchange membrane is made of a polymer or a perfluorinated sheet reinforced with or without polytetrafluoroethylene .
- the thickness of the cylindrical ion-exchange membrane may vary between 0.025mm and 0.5mm depending whether the ion- selective exchange membrane is mounted between two bushings [23] as is seen in Fig.7 or whether the ion-selective exchange membrane is mounted on the inside or around a perforated porous tube [24] which tube-ends are not perforated and not porous over a length of 1 inch from each tube-end.
- the inner electrode [1] is sealed in Port cap A [6] whereas a groove is manufactured to facilitate an O-ring [10] .
- the inner electrode [1] is compressed into the O-ring [10] to form a leak free seal with Port cap A [6] .
- Port A begins at fitting [17] on an outside surface of port A [6] permits the flow of a diluted brine solution through chamber A defined by the outside of the inner electrode tube [1] and the inside of the cylindrical ion-selective exchange membrane [2] .
- Port B begins at fitting [17] on an outside surface of port B cap [5] and permits the flow of a diluted brine solution through chamber B defined by the outside of the cylindrical ion-selective exchange membrane [2] and the inside of outer electrode [3] .
- the outside of port A and port B is a fitting [17] which accepts a tube for introduction or exit of a fluid to the cell assembly.
- These fittings [17] can be a compression fitting, a hose barb, or some other coupling which is appropriate for the system within which the electrolysis cell assembly is to function.
- the orientation of the ports is necessarily to promote a tight spiral flow around the inner electrode tube
- the end pieces can have other configurations as long as the configuration permits for the sealing of the assembly where the compressive force is imposed upon the outer electrode [3] and no significant compressive force is imposed on the cylindrical ion-selective exchange membrane [2] .
- the different types of end pieces can be combined in any combination as long as the appropriate lengths of tubing are chosen and as long as the sections of the end piece are sealed together by compression. While the preferred end piece has been illustrated and described, it will be clear that the invention is not so limited. Modifications, changes, variations, substitutions and equivalents will occur to those skilled in the art without departing from the spirit and scope of the present invention as described in the claims.
- This two chamber cylindrical electrolysis cell can be used with different flow patterns allowing changing of the pH, free-available chlorine content, redox potential, conductivity and osmolality of the dilute Hypochlorous Acid solution.
- a typical flow pattern as seen in Figures 5 and 6 permits approximately 70 to 90% of the diluted brine solution to pass successively through cathode and anode chambers to generate a stable Hypochlorous Acid solution and approximately 10 to 30% of the diluted brine solution to pass though one or more the cathode chambers to generate a Sodium Hydroxide solution.
- the volume of diluted brine solution that passes the electrolysis cells and separately and successively the cathode and the anode chambers can be restricted by closing product valve [25] and waste product valve [26] which are mounted prior to the inlets of the anode or cathode chambers of one of the two electrolysis cells.
- the volume of diluted brine solution from the outlet of the cathode chamber and that is redirected to the inlet of the anode chamber can be restricted by closing a drain valve [28] that is mounted after the diluted brine solution passed a degassing chamber [27] assembled in the outlet tube of the cathode chamber.
- a preferred alternative flow pattern is to a diluted brine solution first through the cathode chamber, where in the outlet tube a degassing chamber [27] is mounted to release hydrogen gases and allow some of the diluted sodium hydroxide to flow to a storage container [29] and approximately 80 to 90% of the diluted sodium hydroxide is re-entered in the anode chamber.
- a flow-meter and an automatic control valve regulates the flow between 70-90% of the total flow
- a flow-meter and an automatic valve regulates the flow between 10-30% of the total flow, never closing the flow.
- the product-flow passes through the following electrolytic chambers:
- the product-flow undergoes first cathode electrolysis whereas cations are attracted to the cathode. Secondly, the product-flow undergoes anode electrolysis whereas cations are donated to the cathode chamber, passing through the cation ion-exchange membrane. Thirdly the product-flow undergoes a second anode electrolysis in cell 2, whereas anions from the waste-flow are donated to the product-flow passing through the anion ion-exchange membrane and accepted in the anode chamber by the product-flow.
- This flow configuration can be labeled as cathode to anode whereas part of the cathode product is drained.
- the waste- flow undergoes only cathode electrolysis in cell 2 whereas it donates anions to the product-flow.
- a the aqueous brine solution stream flow from a cell with cation ion-exchange membrane to a second cell with an anion ion-exchange membrane, this flow configuration can be labeled as cation to anion.
- the pH of the Hypochlorous Acid can be effectively and accurately controlled by regulating the drain-valve [28] as well regulating simultaneously the waste-valve [26] and product-valve [25].
- By opening the drain-valve initially hydrogen gas, but when opening more also sodium hydroxide solution is stripped (drained) from the product-flow.
- pH of the hypochlorous acid solution will be the highest when the drain-valve is closed, by opening the drain-valve [28] the volume of the product-flow is reduced allowing it more time to pass successively through the two anode chambers whereas no hydrogen gas-bubbles are passing with the product-flow thus not interfering the anode electrolysis of the (reduced) product-flow. Absence of gas bubbles and less volume result in a lower pH of the hypochlorous Acid.
- the volume of the waste-flow and product-flow can be adjusted, reducing the waste-flow (and increasing the product-flow) changes the donor-acceptor relation within cell 2. Less waste-flow means that less anions are fed into the cathode chamber of cell 2, which means that less anions are donated to the anode chamber and thus less anions pass through the anion ion-exchange chamber. More waste-flow will increase the ph of the hypochlorous acid solution.
- Another neutral hypochlorous acid solution with a ph between 3.5 and 7 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 stable hypochlorous acid solution is generated by having the product-flow pass through the following electrolytic chambers :
- the product-flow undergoes first cathode electrolysis whereas anions are attracted to the anode, secondly, the product-flow undergoes anode electrolysis whereas anions are donated to the anode chamber, passing through the anion-selective exchange membrane. Thirdly the product-flow undergoes a second anode electrolysis in cell 2, whereas cations from the product-flow are donated to the waste-flow passing through the cation-selective exchange membrane and accepted in the cathode chamber by the waste-flow.
- This flow configuration can be labeled as cathode to anode to anode whereas part of the cathode product is drained.
- the waste-flow undergoes only cathode electrolysis in cell 2 whereas it accepts cations to the waste-flow.
- this flow configuration can be labeled as anion to cation anion.
- the pH of the hypochlorous acid can be effectively and accurately controlled by regulating the drain-valve [28] as well regulating simultaneously the waste-valve [26] and product-valve [25] .
- By opening the drain-valve initially hydrogen gas is released through the vent, but when opening more also sodium hydroxide solution is stripped (drained) from the product-flow.
- ph of the hypochlorous acid solution will be the lowest when the drain-valve is closed.
- By opening the drain-valve the volume of the product-flow is reduced allowing it more time to pass successively through the two anode chambers whereas no hydrogen gas- bubbles passing with the product-flow thus not interfering the anode electrolysis of the (reduced) product-flow. Absence of hydrogen gas bubbles and less volume result in a higher pH of the Hypochlorous Acid.
- the volume of the waste-flow and product-flow can be adjusted. Reducing the waste-flow (and increasing the product-flow) changes the donor-acceptor relation within cell 2. Less waste-flow means that less cation can be accepted into the cathode chamber of cell 2, which means that less cations are donated to the cathode chamber and thus less cations pass through the cation- selective exchange chamber. More waste-flow will decrease the pH of the hypochlorous acid solution.

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.
