Description

  The present invention relates to a method for producing sterilized water for producing sterilized water by sterilizing or sterilizing water containing chlorine components such as seawater, and a production apparatus for producing sterilized water.

  Water is a substance that is used in a wide range of fields such as drinking water, cooking water, food processing water, sanitary processing water, ice making water, various industrial water, air conditioning water, swimming pool water, etc. It is an indispensable substance. In many of these fields of use, it is desirable to have a sterile condition in which various bacteria are not substantially present, especially in the field of water directly related to humans. Water is requested. For this reason, development of a method for producing aseptic water or sterilized water that should cope with such a request has been requested. As an example of means to cope with such a request, “a method for producing aseptic water and its device” A patent application has been filed under the name (see Patent Document 1).

  The production method and the production apparatus proposed in the patent document are intended to produce neutral aseptic water, and as the use of the aseptic water, food processing water, swimming pool water, buildings It is intended to be used for water in the internal water and air conditioner cooler box. The method for producing aseptic water employs a method of treating with ordinary membrane water using diaphragm water electrolysis using water to be treated as electrolyzed water. In the diaphragm electrolysis, first, electrolyzed water is introduced into the anode-side electrolysis chamber of the diaphragm electrolyzer and electrolyzed, and then the generated electrolyzed water is introduced into the cathode-side electrolysis chamber of the diaphragm electrolyzer. Through these two electrolysis processes, the water to be electrolyzed is oxidized and sterilized by electrolysis in the anode side electrolysis chamber, and the sterilized electrolyzed water is produced in the cathode side electrolysis chamber. Neutralized. Thereby, to-be-processed water (electrolyzed water) is produced | generated in neutral aseptic water.

  It can be said that this production method is an effective production method as long as neutral sterile water is produced. However, in the manufacturing method, the electrolytically generated water generated by the electrolytic treatment in the anode side electrolytic chamber is sterilized, but a large amount of chlorine and oxygen is dissolved, so that dissolved oxygen and dissolved chlorine are not dissolved. Consumable hydrogen gas generated by electrolytic treatment in the cathode side electrolysis chamber is consumed, and the generated sterile water has a high oxidation-reduction potential, in particular, drinking water, ice making water, cooking water, food processing water, etc. It cannot be a sterile water having a low redox potential and being substantially negative, which is suitable as water for human consumption.

  The present inventor has eagerly studied to produce sterile water (sterilized reduced water) having a low oxidation-reduction potential and substantially negative, and has developed a method and an apparatus for producing sanitized reduced water. A patent application has been filed under the name “Method and apparatus for producing sterilized reduced water” (Japanese Patent Application No. 2004-40234).

  The method for producing sterilized water is obtained by subjecting treated water to electrolyzed water in the anode-side electrolysis chamber of the diaphragm electrolyzer, and degassing the treated water generated by the electrolysis treatment with a degassing membrane. And it is a manufacturing method which comprises subjecting the treated water produced | generated by the deaeration process to electrolysis in the cathode side electrolysis chamber of a diaphragm electrolyzer. According to the manufacturing method, dissolved oxygen and dissolved chlorine in the sterilized electrolytically generated water generated by the electrolytic treatment in the anode side electrolytic chamber are degassed by the gas-liquid separation action of the degassing membrane, and the cathode side There is virtually no dissolved oxygen or dissolved chlorine that consumes useful hydrogen gas generated by electrolytic treatment in the electrolysis chamber. For this reason, the electrolyzed water produced in the cathode side electrolysis chamber is sterilized water having a low redox potential and being substantially negative, and substantially sterile water.

Moreover, the manufacturing apparatus for implementing the manufacturing method of the said disinfecting water mainly has a diaphragm electrolyzer and a gas-liquid separator. The diaphragm electrolyzer is composed of a tank body, a diaphragm that partitions the tank body into a pair of compartments, a pair of electrodes that are disposed in the partitioned compartments and form each compartment in each electrolytic chamber, It is comprised by the some spacer which is arrange | positioned in each electrolytic chamber and hold | maintains between each electrode and a diaphragm at predetermined spacing. The gas-liquid separator is interposed in a flowing water line connecting the downstream side of the anode-side electrolysis chamber and the upstream side of the cathode-side electrolysis chamber of the diaphragm membrane electrolytic cell, and electrolysis generated in the anode-side electrolysis chamber. The produced water is degassed while passing through the gas-liquid separator.
Japanese Patent No. 2714662

  By the way, in the method for producing sterilized water using the device for producing sterilized water, the electrolyzed water produced in the anode-side electrolysis chamber is connected to the water-flow conduit that connects the anode-side electrolysis chamber and the cathode-side electrolysis chamber. Since the deaeration process is performed in the middle of the process, a difference occurs between the pressures in the two electrolytic chambers, and the internal pressure in the anode side electrolytic chamber becomes higher than the internal pressure in the cathode side electrolytic chamber. For this reason, the diaphragm that partitions both electrolytic chambers is pressed and bent by the internal pressure of the anode side electrolytic chamber toward the cathode side electrolytic chamber, and the distance between the diaphragm and the electrode in the cathode side electrolytic chamber is reduced. The flow path in the side electrolysis chamber becomes narrower than the set size. As a result, it is difficult to ensure the flow rate in the cathode side electrolysis chamber of the electrolyzed water subjected to deaeration treatment to the set flow rate, and the electrolysis treatment in the cathode side electrolysis chamber of the electrolysis water subjected to deaeration treatment is sufficient. Will not be able to.

  In order to solve such a problem, it is indispensable to secure the flow rate in the cathode side electrolysis chamber of the electrolyzed electrolyzed water that has been deaerated. In order to cope with this, it is conceivable to prevent the diaphragm from bending toward the cathode side electrolytic chamber by forming the spacers hard, increasing the number of the spacers, and making the diaphragm hard. However, it is almost impossible to take such measures. In addition, if the cathode side electrolysis chamber is set large in advance, the flow rate of the electrolyzed electrolyzed water that has been deaerated can be substantially maintained at the set flow rate. There is a problem that the electrolytic cell is enlarged.

  Accordingly, an object of the present invention is to subject the water containing a chlorine component such as seawater as water to be treated to electrolytic treatment in the anode electrolysis chamber of the diaphragm membrane electrolytic cell, and use the treated water generated by the electrolytic treatment as a degassing membrane. And a method for producing sterilized water comprising subjecting the treated water produced by the deaeration treatment to electrolytic treatment in the cathode-side electrolysis chamber of the diaphragm electrolytic cell, and a method for carrying out the production method. In the manufacturing apparatus, the above-mentioned problems are to be solved.

It is a method for producing sterilized water, comprising deaeration treatment with a deaeration membrane and electrolytic treatment of the treated water generated by the deaeration treatment in the cathode side electrolysis chamber of the diaphragm membrane electrolytic cell.

  Thus, in the method for producing sterilized water according to the present invention, a permeable degassing membrane having water permeability and gas-liquid separation capability is adopted as a diaphragm for partitioning the anode side electrolysis chamber and the cathode side electrolysis chamber. A separation membrane electrolytic cell is used, and the water to be treated is electrolyzed in the anode-side electrolysis chamber, and the electrolyzed water generated by the electrolysis treatment is permeated through the water-permeable degassing membrane. The electrolytically produced water that has been treated and deaerated is subjected to electrolytic treatment in the cathode-side electrolysis chamber. In the method for producing sterilized water according to the present invention, a gas-liquid separation membrane formed by filling a water-permeable casing with a large number of hollow fibers can be adopted as the water-permeable degassing membrane.

  Moreover, the apparatus for producing sterilized water according to the present invention is a production apparatus for carrying out the method for producing sterilized water according to the present invention, and is a cylindrical tank body having a predetermined length, and the tank body. A first electrode disposed on the base end side of the first tank, and a second electrode disposed on the distal end side in the tank body and positioned at a predetermined distance from the first electrode; And the water-permeable deaeration membrane disposed between the electrodes in the tank body, and the space between the water-permeable deaeration membrane and the first electrode and the second electrode. It is characterized by being formed in the electrolysis chamber. In the production apparatus according to the present invention, a hollow fiber constituting a gas-liquid separator formed by filling a water-permeable casing with a large number of hollow fibers can be employed as the water-permeable deaeration membrane.

  In the manufacturing apparatus according to the present invention, an annular body made of a conductive material can be adopted as the first electrode and the second electrode. In this case, the first electrode is fitted and fixed in the tube portion constituting the base end side of the tank body, or interposed between the divided tube portions constituting the base end side portion of the tank body. And, the second electrode is fitted and fixed in a tube part constituting the tip side of the tank body, or interposed between divided pipe parts constituting the tip side part of the tank body. Can be positioned.

  In the manufacturing apparatus according to the present invention, rod-shaped bodies made of a conductive material can be employed as the first electrode and the second electrode. In this case, the first electrode is inserted and positioned from the outer peripheral side of the tube portion constituting the base end side of the tank main body, and the second electrode is positioned on the tip end side of the tank main body.

  The apparatus for producing sterilized water according to the present invention is composed mainly of a diaphragm membrane electrolyzer that employs a water-permeable degassing membrane as a diaphragm that partitions the anode-side electrolysis chamber and the cathode-side electrolysis chamber. is there. In the electrolysis operation using the manufacturing apparatus, for example, the first electrode is set as the anode side electrode and the second electrode is set as the cathode side electrode, and the water to be treated is treated water from the base end side of the tank body. Introduce into the tank body. The introduced electrolyzed water passes through the first electrode (anode electrode) located in the tank body to reach the water permeable deaeration film, passes through the water permeable deaeration film, and passes through the second electrode ( It passes through the cathode electrode) and is led out from the front end side of the tank body. In the said manufacturing apparatus, a water-permeable deaeration membrane functions also as a diaphragm of the conventional diaphragm membrane electrolytic cell.

  For this reason, the water to be treated is electrolyzed in an anode-side electrolysis chamber formed between the first electrode in the tank body and the water-permeable degassing membrane, and sterilized to be aseptic or nearly aseptic. Electrolyzed water (sanitized water). The electrolytically generated water is deaerated while passing through the water-permeable deaerated membrane, so that dissolved oxygen and dissolved chlorine are volatilized and removed. The electrolytically generated water that has been deaerated is neutralized by further electrolytic treatment in a cathode-side electrolysis chamber formed between the water-permeable deaerated membrane and the second electrode. As a result, sterilized water having a substantially neutral and negative oxidation-reduction potential is produced. That is, according to the manufacturing apparatus according to the present invention, the manufacturing method according to the present invention can be easily performed.

  As described above, the manufacturing apparatus according to the present invention functions in the same way as the manufacturing apparatus for sterilized water mainly composed of a conventional diaphragm membrane electrolytic cell equipped with a deaeration processor, but the anode-side electrolysis chamber and the cathode-side electrolysis. A water-permeable deaeration membrane is employed as a diaphragm that partitions the chamber, and electrolytically generated water generated in the anode-side electrolysis chamber is introduced through the diaphragm into the cathode-side electrolysis chamber. Such a method is completely different from the method performed by the above-described conventional manufacturing apparatus, and is a problem in the conventional manufacturing apparatus, between the anode-side electrolysis chamber and the cathode-side electrolysis chamber. The pressure difference that occurs is not a problem at all.

  For this reason, in the manufacturing apparatus according to the present invention and the manufacturing method according to the present invention implemented using the manufacturing apparatus, the problem caused by the pressure difference generated between the anode-side electrolysis chamber and the cathode-side electrolysis chamber is not exist. That is, due to the pressure difference, the diaphragm is pressed and bent toward the cathode side electrolysis chamber by the internal pressure of the anode side electrolysis chamber, and the distance between the diaphragm and the electrode in the cathode side electrolysis chamber becomes narrow, and the cathode side electrolysis chamber The problem is that the flow path cannot be secured at the set size, and as a result, the flow rate in the cathode side electrolysis chamber of the deaerated electrolytically generated water cannot be secured at the set flow rate. Many problems such as the problem that the electrolytic treatment in the cathode side electrolysis chamber of the deaerated electrolytically generated water cannot be sufficiently performed due to this problem are solved.

  In addition, the manufacturing apparatus according to the present invention adopts a method in which the deaeration process is performed in a diaphragm that forms a partition between the anode side electrolysis chamber and the cathode side electrolysis chamber, by largely changing the idea from the conventional one. Indispensable in the conventional manufacturing apparatus, there are a flowing water pipe connected to the downstream side of the anode-side electrolysis chamber and the upstream side of the cathode-side electrolysis chamber, and a deaeration processor interposed in the flowing water pipe. It is unnecessary. Therefore, the manufacturing apparatus according to the present invention has an advantage that it can be significantly reduced in size compared with the conventional manufacturing apparatus of this type.

  The present invention relates to a method and apparatus for producing sterilized water. The production apparatus according to the present invention performs electrolytic treatment in the anode-side electrolysis chamber of a diaphragm membrane electrolytic cell using water containing a chlorine component such as seawater as treated water, and uses the treated water generated by the electrolytic treatment as a degassing membrane. This is a production apparatus capable of carrying out a method for producing sterilized water, which comprises subjecting the treated water produced by the deaeration treatment to the electrolytic treatment of the treated water generated by the deaeration treatment in the cathode side electrolysis chamber of the diaphragm membrane electrolytic cell. FIG. 1 shows a basic form of a manufacturing apparatus according to the present invention, and FIGS. 2 to 4 show specific embodiments of the manufacturing apparatus.

  As shown in FIG. 1, the manufacturing apparatus according to the present invention basically has a cylindrical tank body 10a having a predetermined length, and a first electrode 12 disposed on the base end side in the tank body 10a. A second electrode 13 disposed on the front end side in the tank body 10a and positioned at a predetermined distance from the first electrode 12, and the first electrode 12 and the first electrode 12 in the tank body 10a. The gas-liquid separator 20 is disposed between the second electrodes 13 with a predetermined interval.

  The gas-liquid separator 20 is formed by filling a water-permeable casing 21 with a number of hollow fibers 22, and a negative intake pressure is applied to the casing 21 through an intake pipe 23. Yes. The gas-liquid separator 20 is located at a substantially central portion in the longitudinal direction in the tank body 10a, and forms a space between the first electrode 12 in the anode-side electrolysis chamber R1, and the second electrode. 13 is formed in the cathode side electrolysis chamber R2. Accordingly, the gas-liquid separator 20 also functions as a diaphragm that partitions and molds the anode-side electrolysis chamber R1 and the cathode-side electrolysis chamber R2 with a large number of filled hollow fibers 22 constituting a water-permeable deaeration membrane. To do.

  In the electrolysis operation using the manufacturing apparatus according to the present invention, for example, the first electrode 12 is set as the anode side electrode, the second electrode 13 is set as the cathode side electrode, and the water to be treated is supplied to the tank body. It introduce | transduces in the tank main body 10a from the base end side of 10a. The introduced water to be treated passes through the first electrode 12 (anode electrode) and the anode-side electric chamber R1 located in the tank body 10a to reach the gas-liquid separator 20, and the gas-liquid separator 20 is The light passes through the cathode side electrolysis chamber R2 and the second electrode 13 (cathode electrode), and is led out from the front end side of the tank body 10a. During this time, the gas-liquid separator 20 functions as a diaphragm of a conventional diaphragm membrane electrolytic cell and also functions as a deaeration treatment device.

  For this reason, the water to be treated introduced into the tank body 10a is electrolyzed in the anode-side electrolysis chamber R1 between the first electrode 12 and the gas-liquid separator 20 in the tank body 10a to be aseptic or aseptic. It becomes electrolyzed water (sanitized water) sterilized to a close state. The electrolyzed water is degassed while passing through the hollow fiber 22 of the gas-liquid separator 20, and the dissolved oxygen and dissolved chlorine are volatilized and removed (degassed). The electrolyzed water that has been degassed is subjected to electrolysis in the cathode side electrolysis chamber R2 between the gas-liquid separator 20 and the second electrode 13 to be neutralized, and is substantially neutral and redox potential. Becomes negative sanitized water.

  As described above, the manufacturing apparatus according to the present invention functions in the same manner as a conventional apparatus for manufacturing sterilized water mainly composed of a diaphragm membrane electrolytic cell equipped with a degassing apparatus, but the anode-side electrolysis chamber R1 and the cathode. Adopting a water permeable degassing membrane formed by the hollow fiber 22 of the gas-liquid separator 20 as a diaphragm that partitions the side electrolysis chamber R2, the electrolyzed water generated in the anode side electrolysis chamber R1 is permeable to water. A method is adopted in which the gas is introduced through the gas film 22 into the cathode-side electrolysis chamber R2. Such a method is a completely different method from the above-described conventional manufacturing method and manufacturing apparatus, and is an epoch-making method that cannot be predicted from these methods. The pressure difference generated between the anode-side electrolysis chamber and the cathode-side electrolysis chamber does not become a problem.

  For this reason, the manufacturing apparatus according to the present invention and the manufacturing method according to the present invention implemented using the manufacturing apparatus are caused by a pressure difference generated between the anode-side electrolysis chamber R1 and the cathode-side electrolysis chamber R2. There is no problem. That is, due to the pressure difference, the diaphragm (water-permeable deaeration film 22) is pressed toward the cathode-side electrolysis chamber R2 by the internal pressure of the anode-side electrolysis chamber R1, and the diaphragm and the second electrode in the cathode-side electrolysis chamber R2 There is no problem that the interval between 13 becomes narrow and the flow path in the cathode side electrolysis chamber R2 cannot be secured to a set size. In addition, due to such a problem, the flow rate in the cathode side electrolysis chamber R2 of the deaerated electrolytically generated water cannot be secured at the set flow rate, and due to this, the deaerated treatment is performed. There is no problem that the electrolytic treatment of the electrolyzed water in the cathode side electrolysis chamber R2 cannot be sufficiently performed.

  In addition, the manufacturing apparatus according to the present invention employs a method in which the deaeration process is performed by a diaphragm that partitions and forms the anode-side electrolysis chamber R1 and the cathode-side electrolysis chamber R2 by adopting a method that largely changes the concept from the conventional one. Therefore, it is indispensable in the conventional manufacturing apparatus, the flowing water conduit communicating the downstream side of the anode side electrolytic chamber and the upstream side of the cathode side electrolytic chamber, and the deaeration interposed in the flowing water conduit A processing device or the like is unnecessary.
