Description

Oxygenated water treatment apparatus, oxygenated water treatment method, and oxygenated water

[0001] The present invention relates to an oxygenated water treatment apparatus, an oxygenated water treatment method, and oxygenated water, and particularly relates to an oxygenated water treatment apparatus, an oxygenated water treatment method, and oxygenated water that can extend the dissolved state of oxygen for a long time.

[0002] In Patent Document 1 included by the inventor of the present invention, oxygenated water with a dissolved oxygen concentration of approximately 50 ppm immediately after liberation, a dissolved oxygen concentration of 48.1 ppm four days after liberation (a decrease of approximately 3.8% from immediately after liberation), and a dissolved oxygen concentration of 34.5 ppm thirty-one days after liberation (a decrease of approximately 31% from immediately after liberation) is disclosed ((0168) paragraph).

[0003] Further, Patent Document 1 states that in oxygenated water produced by a conventional pressurization method, even when the dissolved oxygen concentration during pressurization is 40 ppm, the dissolved oxygen concentration drops sharply to 8 ppm to 9 ppm at the time of opening and becomes the same as the saturated dissolved oxygen concentration of normal water ((0161) paragraph).

[0004] Japanese Patent Application Laid-Open No. 2014-014357

[0005] Here, as understood from the description in paragraph (0161) of Patent Document 1, the oxygenated water disclosed in Patent Document 1 employs a manufacturing method different from the conventional pressurization method, and therefore can achieve the retention of a high dissolved oxygen concentration.

[0006] An object of the present invention is to provide an oxygenated water treatment apparatus, an oxygenated water treatment method, and oxygenated water that can achieve a low dissolved oxygen concentration with a low monthly reduction rate without adopting the manufacturing method disclosed in Patent Document 1.

[0007] In order to solve the above problems, the oxygenated water treatment apparatus of the present invention applies an electric field based on an electric signal having a voltage value of -30 kV to -10 V and a current value of 0.01 mA to 10 mA to oxygenated water for 5 h to 50 h.

[0008] These parameters have the industrial rationality and technical significance described below, and the same applies to the parameters of the oxygenated water treatment method and hydrogenated water of the present invention.

[0009] The lower limit of the voltage is derived from the conditions under which a certain electric field effect can be obtained. A voltage of -10V may be sufficient to generate a high voltage for general charging of water, but if an electric field is to be applied, methods that do not involve directly immersing the electrodes in water (e.g., electrostatic atomization, corona discharge) should also be considered. In that case, it would be difficult to create an effective electric field in space with a voltage of this magnitude.

[0010] The voltage limit is derived from conditions such as avoiding discharge and equipment load. Exceeding a high voltage of -30kV approaches the dielectric breakdown voltage of air (approximately 30kV / cm), making unintended discharges (such as arc discharges) more likely. Preventing this through insulation design directly leads to larger equipment and increased costs, so this limit was set.

[0011] The lower limit of the current is derived from the conditions for excitation and ensuring reactivity. The current value of 0.01 mA is the boundary at which the desired effect (e.g., radical generation, cluster refinement, etc.) will not appear at a measurable level unless this amount of energy is input.

[0012] The upper limit of the current is derived from the need to avoid excessive electrolysis and safety issues. A current value of 10 mA is chosen because anything higher would deviate from the purpose of stabilizing dissolved oxygen.

[0013] The time range for oxygenated water is derived from the condition of ensuring the stability of dissolved oxygen. If the time is less than 5 hours, the time after oxygen dissolution is short, and the dissolved oxygen concentration will not be uniform or stable. If the time exceeds 50 hours, the viscosity will no longer change. Therefore, the effect reaches its limit.

[0014] Furthermore, the oxygenated water treatment method of the present invention involves applying an electric field based on an electrical signal with a voltage value of -30kV to -10V and a current value of 0.01mA to 10mA to oxygenated water for 5 to 50 hours.

[0015] Furthermore, the oxygenated water of the present invention is subjected to an electric field based on an electrical signal with a voltage value of -30kV to -10V and a current value of 0.01mA to 10mA for 5 to 50 hours.

[0016] Furthermore, the oxygenated water of the present invention exhibits a monthly decrease rate of dissolved oxygen concentration of 20% or less.

[0017] Furthermore, the oxygenated water should ideally have a dissolved oxygen concentration of 30 ppm or higher.

[0018] According to the oxygen water treatment apparatus and oxygen water treatment method of the present invention, the oxygen water is composed of O ２ Ya H ２ It is hypothesized that a polarization phenomenon occurs in oxygen, and as long as this polarized state persists for a certain period, the oxygen dissolved in the oxygenated water is less likely to move towards the water surface. In fact, the oxygenated water of the present invention was less prone to a decrease in dissolved oxygen concentration. Embodiment of the Invention

[0019] The oxygen water treatment apparatus, oxygen water treatment method, and oxygen water of the present invention will be described below with reference to the drawings.

[0020] (Oxygenated Water Treatment Device) Figure 1 is a schematic diagram of an oxygenated water treatment device 1000 according to an embodiment of the present invention. Figure 1 shows a mounting base 100, a housing case 200, an electrical signal generator 300, and a transmission line 400, which will be described below.

[0021] The mounting platform 100 is on which the oxygenated water to be treated, which is filled in a container, is placed. The material of the mounting platform 100 can be a non-conductive material such as resin. A conductive material such as aluminum (not shown) is placed between the mounting platform 100 and the storage case 200.

[0022] This conductor may be placed on the upper surface of the mounting base 100, or on the bottom surface of the housing case 200. The size of the conductor should be approximately the same as the bottom surface of the housing case 200 so that an electric field can be uniformly applied to the oxygenated water filled in the container housed in the housing case 200.

[0023] The storage case 200 is designed to hold containers filled with oxygenated water. In this example, 12 compartments are shown, each capable of holding two containers of approximately 500 mL, but the number and size of compartments are not limited to these.

[0024] Therefore, for example, the size of the storage case 200 can be increased to increase the amount of oxygenated water processed at one time. The storage case 200 can also be a cardboard box for shipping oxygenated water, and for example, it can be made to hold 12 containers (one dozen) without any compartments.

[0025] The electrical signal generator 300 generates an electrical signal to apply an electric field to the oxygenated water filled in the container housed in the housing case 200. This electrical signal can be selected within the range of -30kV to -10V and 0.01mA to 10mA in terms of voltage and current. While there is usually a trade-off between voltage and current, both can be set to low values ​​if the supply time is relatively long. When an electrical signal with these specifications is supplied, depending on the supply time, O ２ Ya H ２ An electric field can be applied to oxygenated water that produces a polarization phenomenon in which a certain degree of polarization of oxygen persists for several months.

[0026] The electrical signaling device 300 may also include a timing means for measuring the supply time of an electrical signal, and a stopping means for stopping the generation or supply of an electrical signal when a predetermined supply time (for example, 5 hours to 50 hours) has arrived as determined by the timing means.

[0027] However, it should be noted that supplying an electrical signal beyond the predetermined supply time does have the negative consequence of increased electricity costs, but it is unlikely to cause any particular harm to the oxygenated water, so it is not essential to equip the electrical signaling device 300 with timing or stopping means.

[0028] The transmission line 400 transmits the electrical signal generated by the electrical signal generator 300 to a conductor. When the electrical signal is transmitted through the transmission line 400, an electric field based on the electrical signal is generated from the conductor.

[0029] Furthermore, since the mounting base 100, which is made of a non-conductive material, functions as a shield, the electric field will be generated on the upper side of Figure 1, relative to a conductor. Therefore, it becomes possible to efficiently apply an electric field to the oxygenated water contained in the housing case 200.

[0030] (Oxygenated Water Treatment Method) First, let's outline the oxygenated water to be treated. On January 30, 2024, the inventor began manufacturing oxygenated water at his own factory located at Aga Material Co., Ltd. (1-8-3 Kusumizu-cho, Akiha-ku, Niigata City), where he serves as representative.

[0031] The method for producing oxygenated water differs from that disclosed in Patent Document 1. However, the method for producing oxygenated water itself is unrelated to the oxygenated water treatment apparatus, oxygenated water treatment method, and oxygenated water of the present invention, so no explanation is provided.

[0032] This oxygenated water was pressurized by adding oxygen while measuring the dissolved oxygen concentration with a Hanne Instruments fluorescent portable dissolved oxygen meter (HI98198), until it met the condition described in paragraph (0161) of Reference 1, "the dissolved oxygen concentration during pressurization is 40 ppm." In other words, this oxygenated water has a dissolved oxygen concentration exceeding 40 ppm.

[0033] Next, at the company's own factory, starting around 11:30 a.m. on January 31, 2024, the oxygenated water was sequentially filled into 500 ml containers, and a total of approximately 350 containers filled with oxygenated water were prepared by around noon on the same day. For the record, the oxygenated water filled into these containers was from the same lot and manufactured under the same conditions.

[0034] Next, a container filled with oxygenated water, arbitrarily selected from among those containers, was placed in the storage case 200. An electrical signal generator 300 generated electrical signals according to the conditions of the following five embodiments 1 to 5, and supplied these signals to a conductor installed on the mounting base 100 via the transmission line 400 for approximately 24 hours (from around 11:30 a.m. on January 31, 2024 to around 11:30 a.m. the following day), thereby applying an electric field to the oxygenated water.

[0035] Furthermore, the humidity levels in Niigata City at three-hour intervals from noon on January 31, 2024, to noon the following day, during the supply of electrical signals, were 54%, 38%, 53%, 66%, 80%, 80%, 86%, 75%, and 69% (Japan Meteorological Agency website). Humidity during the supply of electrical signals affects the electric field applied to oxygenated water and, consequently, its ability to retain dissolved oxygen concentration.

[0036] Example 1 (54 pieces): Voltage value: -10 kV, Current value: 0.01 mA Example 2 (54 pieces): Voltage value: -6 kV, Current value: 0.01 mA Example 3 (54 pieces): Voltage value: -1 kV, Current value: 0.01 mA Example 4 (54 pieces): Voltage value: -0.1 kV, Current value: 0.10 mA Example 5 (54 pieces): Voltage value: -0.01 kV, Current value: 1.00 mA Comparative Example (54 pieces): No electrical signal applied

[0037] (Oxygenated water) The inventor opened two containers of oxygenated water for each of the examples and the comparative example at around noon every day for about one month from February 1st to February 27th, 2024, and measured the dissolved oxygen concentration (ppm) of the oxygenated water in each container using the above-mentioned dissolved oxygen meter.

[0038] The reason for taking "two at a time" is to confirm that the variation in the individual differences of the oxygenated water produced in the same lot is within the allowable range and to conduct discussions on reasonable measurement results. In case the variation was outside the allowable range, we intended to increase the number of containers, but since the variation was very small, we decided to summarize the measurement results of "two at a time".

[0039] Tables 1 to 3 are tables showing the measurement results of the dissolved oxygen concentration (ppm) of the oxygenated water for each of the examples and the comparative example. Table 1 shows the "initial" measurement results from February 1st to February 9th, 2024, Table 2 shows the "mid-term" measurement results from February 10th to February 18th, and Table 3 shows the "final" measurement results from February 19th to February 27th. Note that it should be noted that the initial, mid-term, and final are only relative time periods.

[0040]

[0041]

[0042]

[0043] In Tables 1 to 3, in addition to the above measurement results, the noon temperature (°C) in Aoba-ku, Niigata Prefecture is also described. Dissolved oxygen is affected by the temperature at the time of measurement, and the higher the temperature, the lower the value. This can be confirmed, for example, from the fact that among the temperature and dissolved oxygen concentration described in the upper row of Example 1 in Table 2, the dissolved oxygen concentration on "February 15th" with a relatively high temperature of "10.1°C" is relatively low at "38.79 ppm", while the dissolved oxygen concentration on "February 16th" with a relatively low temperature of "2.5°C" is relatively high at "38.92 ppm".

[0044] In addition, Tables 1 to 3 also describe the temperature and dissolved oxygen concentration of the "9-day average" in each table for each example and comparative example, and the "average difference" of the 9-day average of the dissolved oxygen concentration between Example 1, which had the best result among the examples, and other examples and comparative examples.

[0045] Hereinafter, the measurement results of the dissolved oxygen concentration of the oxygen water in each example and comparative example will be discussed.

[0046] Generally speaking first, there is a clear difference in the dissolved oxygen concentration between the oxygen water of each example and the oxygen water of the comparative example. This is because the "average difference" of the dissolved oxygen concentration related to the comparative example is orders of magnitude larger than the "average difference" of the dissolved oxygen concentration related to each example at any of the initial, middle, and final stages, and that "average difference" gradually widens as it progresses from the initial to the middle and final stages.

[0047] On the other hand, there is no significant difference in the dissolved oxygen concentration among the oxygen waters of each example. This can be evaluated as such because the "average difference" of the dissolved oxygen concentration related to each example is less than 1.00 ppm at any of the initial, middle, and final stages. The largest "average difference" is "0.91 ppm" related to Example 5 in Table 2.

[0048] Furthermore, although the dissolved oxygen concentration for each example is not shown in Table 3 as of February 28th, one month after filling the containers, the decrease from the initial 40.00 ppm was within 5% (38.00 ppm or higher), while the dissolved oxygen concentration for the comparative examples did not fall within 20% (a decrease of 20.21% from 37.20 ppm to 29.68 ppm in comparative example (1), and a decrease of 20.02% from 37.10 ppm to 29.67 ppm in comparative example (2)).

[0049] Next, we will examine each example in detail. Among the examples and comparative examples, the oxygenated water in Example 1 had the largest absolute value of the electrical signal voltage, the smallest electrical signal current, and the highest dissolved oxygen concentration at all stages (initial, middle, and final) (39.12 ppm, 38.83 ppm, and 39.24 ppm).

[0050] In Example 2, the oxygenated water had a 4kV lower absolute value of the electrical signal voltage compared to the oxygenated water in Example 1, the same electrical signal current value, and high dissolved oxygen concentrations at all stages (38.91 ppm, 38.56 ppm, and 38.94 ppm). The "average difference" tended to widen slightly as the stages progressed from the initial to the intermediate to the final stage (0.22 ppm, 0.27 ppm, and 0.31 ppm).

[0051] In Example 3, the oxygenated water had a 9kV lower absolute voltage value of the electrical signal compared to the oxygenated water in Example 1, the same current value of the electrical signal, and the dissolved oxygen concentration was relatively high at all stages (38.56 ppm, 38.21 ppm, and 38.79 ppm). The "average difference" tended not to widen much as the stages progressed from the initial to the intermediate to the final stage (0.56 ppm, 0.62 ppm, and 0.46 ppm).

[0052] To summarize, the measurement results of the dissolved oxygen concentration in the oxygenated water in Examples 1 to 3 indicate that the lower the voltage value of the electrical signal, the lower the ability of the oxygenated water to retain dissolved oxygen concentration. Therefore, it can be said that the voltage value of the electrical signal must be kept above a certain level.

[0053] Furthermore, comparing the relationship between the oxygenated water of Example 1 and the oxygenated water of Example 2, and the relationship between the oxygenated water of Example 2 and the oxygenated water of Example 3, although the difference in the absolute value of the voltage is greater in the latter case (5kV) than in the former case (4kV), the "average difference" at the end is smaller in the latter case (0.15ppm = 0.46ppm - 0.31ppm) than in the former case (0.31ppm). Therefore, it can be said that there is a high possibility that a breakthrough in the ability to retain dissolved oxygen concentration occurs when the absolute value of the voltage exceeds 6kV.

[0054] Next, in relation to the oxygenated water of Example 3, the absolute value of the voltage of the electrical signal of the oxygenated water of Example 4 is 1 / 10 times, while the current value of the electrical signal is 10 times. The "average difference" for the oxygenated water of Example 4, when compared to the "average difference" for the oxygenated water of Example 3, shows a slight decrease in the ability to retain dissolved oxygen concentration. However, the final difference in their "average differences" is only "0.1 ppm (= 0.56 ppm - 0.46 ppm)".

[0055] In the case of the oxygenated water in Example 5, the absolute value of the voltage of the electrical signal is 1 / 10th of that of the oxygenated water in Example 4, while the current value of the electrical signal is 10 times greater. The "average difference" for the oxygenated water in Example 5, when compared to the "average difference" for the oxygenated water in Example 4, shows a slight decrease in the ability to retain dissolved oxygen concentration. Furthermore, the difference in these "average differences" at the end of the experiment widens to "0.25 ppm (= 0.81 ppm - 0.56 ppm)".

[0056] In summary, while the absolute value of the electrical signal voltage was reduced in the oxygenated water of Example 4 compared to the oxygenated water of Example 3, and the current value was increased compared to the oxygenated water of Example 5 compared to the oxygenated water of Example 4, the ability to retain dissolved oxygen concentration tends to weaken. Therefore, it is highly likely that it is preferable to keep the absolute value of the electrical signal voltage at around 1 kV or higher.

[0057] Furthermore, it was found that when oxygenated water was rapidly filled into containers, the dissolved oxygen concentration was relatively low from the start. The lowest concentration was 28.11 ppm. However, when the oxygenated water was measured one month after filling the containers, it had decreased to 27.27 ppm, a decrease of less than 2.98%.

[0058] As described above, the oxygenated water produced by the oxygenated water treatment method of the present invention using the oxygenated water treatment apparatus of the present invention can be made less susceptible to a decrease in dissolved oxygen concentration.

[0059] This is a schematic diagram of an oxygen water treatment apparatus 1000 according to an embodiment of the present invention.
