Description

  The present invention relates to a redox potential water production apparatus.

  In recent years, redox potential water has attracted attention as environmentally friendly and human-friendly water. Here, the oxidation-reduction potential (hereinafter referred to as “ORP” as appropriate. “ORP” is an abbreviation for Oxidation Reduction Potential) is a state in which the substance is likely to oxidize other substances or is easily reduced. It is an index indicating whether or not it is in a state. In addition, ORP of tap water is + 200- + 800mV normally, and human body fluid is -500- + 250mV (for example, refer nonpatent literature 1).

By the way, conventionally, redox potential water has been produced by electrolyzing water. Specifically, when the water is electrolyzed, the ORP of the cathode-side water increases to the minus side, and the pH increases and becomes alkaline. Therefore, neutralization was performed by adding an acid to the water to obtain reduction potential water that was neutral and ORP increased to the negative side (see, for example, Patent Document 1).

  The cylindrical case 30 includes a case main body 31, an inflow pipe 32 joined to the upstream end of the case main body 31, and an outflow pipe 33 joined to the downstream end of the case main body 31.

  The case body 31 has a cylindrical shape, and flange portions 37 that are joined to the inflow pipe 32 and the outflow pipe 33 are formed at both ends. The internal space of the case body 31 has a cylindrical shape with a constant diameter.

  The inflow pipe 32 and the outflow pipe 33 have the same shape. That is, a pipe connection part 34 connected to the pipe 11 is formed at one end of the inflow pipe 32 and the discharge pipe 33, and a flange part 35 joined to the case body 31 is formed at the other end. The outer diameter is increased in a stepped shape from the pipe connection portion 34 toward the flange portion 35. The inner diameters of the inflow pipe 32 and the outflow pipe 33 are constant.

  Of the inflow pipe 32 and the outflow pipe 33, a cylindrical boss 36 stands from an opening edge (end surface 35 </ b> T of the flange portion 35) on the side joined to the case body 31. When the inflow pipe 32 and the outflow pipe 33 are joined to both ends of the case main body 31, the cylindrical boss 36 enters the internal space of the case main body 31. The above is the description of the cylindrical case 30.

  Now, the mixing wall 40 is as follows. As shown in FIG. 3, the mixing wall 40 has a configuration in which a plurality of small holes 42 (corresponding to “through holes” in the present invention) are formed through a disc member 41. The disc member 41 is made of, for example, metal (specifically, stainless steel or brass), and the outer diameter thereof is substantially the same as the inner diameter of the case main body 31. The small hole 42 extends in the plate thickness direction (vertical direction in FIG. 2) of the mixing wall 40 and has an inner diameter of, for example, 2 μm.

  As shown in FIG. 2, the mixing wall 40 is disposed inside the cylindrical case 30 (specifically, the case main body 31) so as to overlap in the axial direction of the cylindrical case 30. A spacer (for example, an O-ring) 45 is sandwiched between the mixing walls 40. The mixing walls 40 adjacent to each other are overlapped at a predetermined interval by the spacer 45, and the mixing walls 40 allow the internal space of the case main body 31 to correspond to a plurality of flat cylindrical space portions 46 (corresponding to “regions” in the present invention). To be). In other words, the mixing wall 40 and the space 46 are alternately provided in the case body 31 along the axial direction of the case body 31. Here, the plurality of mixing walls 40 accommodated inside the case body 31 are fitted inside the case body 31, and the inflow pipe 32 and the outflow pipe 33 are assembled to the case body 31. The cylindrical bosses 36 and 36 are pressed from the side and fixedly arranged inside the case main body 31.

  The above is description of the structure of the oxidation-reduction potential water production apparatus 100 in the present embodiment, and the operation and effect will be described below. When redox potential water is produced by the redox potential water production apparatus 100 according to the present embodiment, it is as follows. First, the on-off valve 18 provided in the water pipe 15 is opened, and tap water is sucked by the gas-liquid mixing pump 12. The tap water is sucked at a predetermined flow rate (for example, 10 to 20 L / min) and passes through the cluster size changing device 17 before reaching the gas-liquid mixing pump 12. By passing through the cluster size changing device 17, the cluster size of tap water is reduced and flows into the gas-liquid mixing pump 12 in this state.

  The gas-liquid mixing pump 12 sucks gas from the gas cylinder 13 together with tap water at a predetermined flow rate (for example, 0.2 to 0.4 L / min), and stirs this gas and tap water with a reduced cluster size. After mixing, the mixed fluid is pumped to the mixer 10.

  The mixed fluid of gas and tap water flows into the cylindrical case 30 from the inflow pipe 32 of the mixer 10 and collides with the uppermost mixing wall 40. The mixed fluid that has collided with the mixing wall 40 is pressurized by being pushed into a plurality of small holes 42 formed in the mixing wall 40 and is divided into a plurality of flow paths.

  The mixed fluid that has passed through the small holes 42 of the mixing wall 40 flows into the uppermost space 46. In this space portion 46, when passing through the small hole 42, the mixed fluid divided into a plurality of flow paths merges and the pressure applied to the mixed fluid decreases.

  When the mixed fluid that has flowed into the uppermost space 46 collides with the second-stage mixing wall 40 and passes through the small holes 42, it is again subjected to a strong pressure and finely divided into a plurality of flow paths. Then, after passing through the second-stage mixing wall 40, it flows into the second-stage space 46, where the mixed fluid that has passed through the mixing wall 40 divided into a plurality of flow paths (small holes 42) joins. , The pressure applied to the mixed fluid decreases. Hereinafter, by alternately passing through the mixing wall 40 and the space portion 46, the mixed fluid repeats the diversion and merging, and the pressure applied to the mixed fluid is repeated.

  As a result, the gas in the mixed fluid dissolves in the tap water, and the reduction potential water having a lower oxidation-reduction potential or higher oxidation potential water than the tap water is produced. The redox potential water produced by passing through the mixer 10 flows into the water storage tank 19. When using the redox potential water stored in the water storage tank 19, the on-off valve 27 provided in the supply pipe 22 is opened.

  By the way, in the oxidation reduction potential water manufacturing apparatus 100 of this embodiment, the oxidation reduction potential water manufactured by passing through the mixer 10 can be circulated and allowed to pass through the mixer 10 again. Specifically, the on-off valve 18 provided on the water pipe 15, the on-off valve 27 provided on the supply pipe 22, and the drain valve 24 are all closed, and the on-off valve 21 provided on the circulation pipe 20 is opened. . Then, the oxidation-reduction potential water stored in the water storage tank 19 is returned to the upstream side of the gas-liquid mixing pump 12 through the circulation pipe 20 (may be returned to the upstream side of the cluster size changing device 17). Then, the redox potential water flows into the gas-liquid mixing pump 12, where it is mixed with the gas and then passes through the mixer 10 again.

[Experiment 1]
In order to examine the effect of the oxidation-reduction potential water production apparatus 100 of the present embodiment, the following experiment was conducted. The experimental procedure is as follows. The tap water used in this experiment has a pH of 7.20 and an ORP of +250 mV.
(1) Reduction potential water was manufactured by dissolving hydrogen gas in tap water using the oxidation-reduction potential water manufacturing apparatus 100. Specifically, 30 L of tap water was circulated in the oxidation-reduction potential water production apparatus 100 at a flow rate of 5.8 L / min.
(2) The ORP, dissolved hydrogen amount, and pH of the reduced potential water that has passed through the mixer 10 are measured every preset time, and the number of passes of the reduced potential water to the mixer 10 and the ORP, dissolved hydrogen amount, and pH Each relationship was graphed. In this experiment, the time T when the ORP or the like was measured was converted to the number of passages to the mixer 10 based on the following relational expression.
Number of passes = T · 5.8 / 30

  As shown in the graph of FIG. 4, the ORP of the reduction potential water decreases to −560 mV at a stroke before passing through the mixer 10 about twice (10 minutes after the start of water flow), and then the number of passes is reduced. It gradually decreased with the increase, and decreased to −630 mV when it passed through the mixer 10 about 12 times (60 minutes after the start of water flow). As shown in the graph of FIG. 5, this is presumed to be mainly due to an increase in the amount of dissolved hydrogen as the number of passages to the mixer 10 increases. Moreover, as shown in the graph of FIG. 6, the pH of the reduction potential water hardly changes even when the number of passages to the mixer 10 increases and the ORP value decreases, and the pH of the tap water before passing through the mixer 10. It was almost the same.

  As a result of the experiment, it has been found that when water and hydrogen are mixed using the oxidation-reduction potential water production apparatus 100 of the present embodiment, reduction potential water having a lower ORP value than that of the prior art can be produced. In addition, it was found that the pH change can be suppressed as compared with the case of producing water by electrolysis.

  It has also been found that the ORP of the redox potential water can be maintained for a longer time by increasing the number of passes through the mixer 10.

  As described above, according to the oxidation-reduction potential water production apparatus 100 of the present embodiment, the strength of the fluid pressure applied to the water is repeated in the process in which the mixed water passes through the mixer 10, and The dissolved amount is improved, and the absolute value of the oxidation-reduction potential (ORP) can be made higher than before.

  The oxidation-reduction potential water produced by the oxidation-reduction potential water production apparatus 100 according to the present embodiment is used for cleaning medical equipment and industrial parts (for example, semiconductor parts), processing / manufacturing pharmaceuticals / cosmetics / food, industrial wastewater. It can also be used to treat livestock wastewater, improve water quality of pools, public baths, aquaculture ponds, agricultural water, etc.

[Second Embodiment]
FIG. 7 shows a second embodiment of the present invention. In this second embodiment, the configuration of the oxidation-reduction potential water production apparatus is different from that of the first embodiment. Since other configurations are the same as those in the first embodiment, the same reference numerals are given to the same configurations, and duplicate descriptions are omitted.

  As shown in FIG. 7, in the oxidation-reduction potential water production apparatus 200 of the present embodiment, a deaeration device 25 is provided in the water pipe 15 upstream of the connection portion with the circulation pipe 20. The deaeration device 25 is configured to introduce gas (air) from tap water by introducing tap water into the sealed space and evacuating the sealed space with a pump or the like. Note that the deaeration device 25 is not limited to the vacuum deaeration device described above, and may be one using ultrasonic vibration, for example.

[Experiment 2]
The following experiment was conducted to examine the effect of the oxidation-reduction potential water production apparatus 200 of the present invention. The tap water used in this experiment has a pH of 7.20 and an ORP of +250 mV. Since the procedure of this experiment is the same as that of Experiment 1 described above, description thereof is omitted.

  As shown in the graph of FIG. 8, the ORP of the reducing potential water immediately decreases to about −620 mV immediately after the start of water flow, and passes through the mixer 10 once (5 minutes after the start of water flow). It was -648 mV at the time of passing about 642 mV and about 2 times (10 minutes passed from the start of water flow). Thereafter, the ORP value became substantially constant, and decreased to −650 mV when it passed about 12 times (60 minutes after the start of water flow).

  That is, according to the oxidation-reduction potential water production apparatus 200 of the present embodiment, the ORP can be reduced in a shorter time than the oxidation-reduction potential water production apparatus 100 of the first embodiment that does not include a deaeration device. Moreover, the ORP value could be set to a lower value (see FIG. 8). As shown in the graph of FIG. 9, this is considered to be because the degassing of tap water facilitates the dissolution of hydrogen gas (dissolves quickly) and increases the amount of hydrogen gas that can be dissolved in tap water. . Further, as shown in the graph of FIG. 10, the pH of the reducing potential water hardly changes even when the number of passages to the mixer 10 increases and the ORP value decreases, and the pH of the tap water before passing through the mixer 10. It was almost the same.

  As a result of the experiment, it was found that when water and hydrogen are mixed using the oxidation-reduction potential water production apparatus 200 of the present embodiment, the ORP of the reduction potential water becomes a lower value in a shorter time. In addition, it was found that the pH change can be suppressed as compared with the case of producing water by electrolysis.

  Thus, according to the oxidation-reduction potential water production apparatus 200 of the present embodiment, the amount of gas that can be dissolved in tap water can be further increased by passing the tap water and gas degassed in advance through the mixer 10. The absolute value of the ORP of the produced oxidation-reduction potential water can be further increased.
