Description

Technical Field

[0001] The present invention relates to an apparatus and method for producing functional water in which the structure (average structure) of liquid is changed. Background Art

[0002] It is known that water with a changed structure (functional water) such as electrolyzed water, magnetized water, water with reduced clusters, and water containing nanobubbles behaves differently from ordinary water, and many uses of these waters have been reported.

[0003] Patent document 1 describes the following as a method for producing functional water: microbubbles having a diameter of 500 nm or more are generated in water by passing water through a microbubble generating portion filled with a mesh, fiber, etc., the water containing the microbubbles is brought into contact with a ceramic containing at least one of an oxide of an alkali metal, an oxide of an alkaline earth metal, and an oxide of an element of Groups 8 to 10 to dissolve metal ions, the water containing the metal ions and the microbubbles is ejected from a nozzle, and a shrinking force is applied to the microbubbles in the water to convert them into nano-sized bubbles having a diameter of less than 500 nm.

[0004] In Patent Document 2, as a generator of functional water that can be used in various technical fields, the following structure is proposed: a partition filled with a stainless steel mesh (stainless steel wool) formed into a block, and a partition filled with granular ceramics containing oxides of alkali metals, oxides of alkaline earth metals, and oxides of at least one element selected from elements belonging to Groups 8 to 10 are arranged in series internally.

[0005] Patent Document 3 discloses a stirrer made of binchotan charcoal. The document states that binchotan charcoal not only has an adsorption effect for harmful substances but also has a cluster decomposition effect and has a function of softening water.

[0006] The following is reported in non-patent document 1: ceramic balls are densely packed into a stainless steel cylinder, and tap water is passed through the cylinder at a water pressure of 2 kgf and a flow rate of 15 L / min. The water clusters are reduced due to the non-thermal effect of far-infrared rays emitted by the ceramics. When rice is cooked with functional water with reduced clusters, the water absorption increases and the sugar content increases.

[0007] Non-patent document 2 states that, as the structure of a water cluster, from the experimental fact that there are 10 sites capable of forming hydrogen bonds, it can be assumed that there is a H3O2 in the center of a regular dodecahedron. + .

[0008] Non-patent document 3 describes that the vibration number and intensity in the gas phase are obtained by molecular orbital calculations at the B3LYP / aug-cc-pVDZ level and the MP2 / aug-cc-pVDZ level for water cluster structures ranging from dimers to pentamers.

[0009] Non-Patent Document 4 describes the correlation between two-dimensional LJ fluid and the cluster structure of water.

[0010] The following is recorded in Non-Patent Document 5: Several water molecules are assembled into clusters through hydrogen bonds, and the water molecules constituting the clusters are -12 seconds) unit, and negates the cluster size can be obtained by 17 The half width of the O-NMR peak was measured.

[0011] The following is recorded in Non-Patent Document 6: 17 In the case of drinking water, the size of clusters is determined by the half-width of the O-NMR peak, and the pH-dependent proton exchange rate and 17 The size of the cluster cannot be correctly expressed due to the coupling between O and protons.

[0012] Non-patent document 7 describes the following: NMR analysis method ( 17 The observation time of O-NMR chemical shift method is longer than the relaxation time of the rotational and translational motion of atoms, so the average structure of the liquid can be studied.

[0013] Non-patent document 8 describes the following: using a nuclear magnetic resonance device to perform pure water and tap water 17 As a result of O-NMR measurement, the half width at half maximum of pure water was 65.5 Hz, and the half width at half maximum of tap water was 119.9 Hz.

[0028] Technical problem solved by the invention

[0029] In the functional water manufacturing apparatus disclosed in Patent Documents 1 and 2, stainless steel wool is filled in the upstream part of the pipe and ceramics is filled in the downstream part. That is, micro bubbles are generated in the upstream part and metal ions are dissolved in the water in the downstream part.

[0030] When water mixed with fine bubbles is produced first in this way, it is difficult for the structural change of the water to reduce the size of the clusters to occur on the downstream side.

[0031] As described in Patent Document 3, stirring water with a stirrer using Binchotan as a raw material to change the structure of water to reduce the clusters is less effective. In addition, as shown in Non-Patent Document 1, the effect of changing the structure of water is less effective as contacting ceramics with water.

[0032] Non-Patent Documents 2 to 4 describe the characteristics of clusters, but do not disclose any means for continuously bringing about structural changes that reduce clusters in ordinary tap water.

[0033] Non-patent literature 5 and 6 state that 17 The O-NMR chemical shift method (half width at half maximum) is not suitable for expressing the size of water clusters, but for ordinary tap water, there is no disclosure on causing structural changes by some means.

[0034] Non-patent literature 7 and 8 state that 17 The O-NMR chemical shift method (half peak width) shows the structural changes of water. However, there is no disclosure about the structural changes caused by some means in ordinary tap water.

[0035] Technical means of solving problems

[0036] The inventors of the present invention have confirmed that when water is brought into contact with a ceramic containing an oxide of an alkali metal, an oxide of an alkaline earth metal, or an oxide of at least one element selected from elements belonging to Groups 8 to 10 at a given flow rate (1.5 m / s to 2.0 m / s), the structure of the water changes due to the non-thermal effect of far-infrared rays emitted by the ceramic, but the structural change is not sufficient.

[0037] Therefore, the ash obtained by firing binchotan containing iron components is mixed with the ceramic material to form ceramic particles, and when water is passed through the flow path filled with the ceramic particles at a flow rate of 1.5 m / s to 2.0 m / s, the result is that 17 The spectrum values ​​(half peak width) of O-NMR were 72.0 Hz (1.5 m / s) and 73.0 Hz (2.0 m / s), and it was confirmed that a significant structural change had occurred.

[0038] It should be noted that when unfired Binchotan charcoal is added, 17 The O-NMR spectrum did not change significantly.

[0039] The functional water manufacturing device of the present invention based on the above content is as follows: a water structure changing portion that changes the structure of water is provided in the upstream part of the pipe constituting the water channel, and a micro-bubble generating portion is provided immediately on the downstream side of the water structure changing portion, the water channel has one end as a water inlet and the other end as a water outlet, wherein the water structure changing portion is filled with ceramic particles obtained by granulating and firing a mixture, the mixture is a mixture of ceramic material and ash obtained by firing binchotan charcoal containing iron components, the ceramic material contains at least one of alkali metal oxides, alkaline earth metal oxides, and oxides of elements of Groups 8 to 10, and the micro-bubble generating portion is a contraction portion that exerts a cavitation effect.

[0040] As a functional water production device, a nozzle may be arranged on the downstream side of the contraction portion of the micro-bubble generating portion, and micro-bubbles may be generated in two stages by the contraction portion and the nozzle.

[0041] In the method for producing functional water using the functional water production device, tap water is supplied to the water structure changing part from one end of the pipe constituting the water flow path at a flow rate of 0.1 m / s or more, and the tap water is confirmed to be 17 The O-NMR spectrum value changes to below 97.5 Hz, indicating a change in the structure of water.

[0042] Effects of the Invention

[0043] According to the present invention, the effects of functional water known in the past are further improved, for example, by improving the softening of hard water, improving the penetration of tap water to improve the cleaning effect of washing, promoting the water absorption of plants to maintain freshness, maintaining the health of animals in livestock, improving the water retention when used in cosmetics, and improving the extraction of Chinese herbal medicines.

[0044] Furthermore, according to the present invention, in addition to the effects known in the past, a boiling point of 101°C and a freezing point of -4°C were confirmed.

[0045] Simply by passing tap water through the device of the present invention, structural changes can be induced and functional water containing tiny bubbles can be continuously produced, so it can be used for a wide range of purposes. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] In the functional water production device, a water flow path is formed in the pipe 1 with one end of the pipe 1 serving as a water inlet 2 and the other end of the pipe 1 serving as an outlet 3 .

[0056] The upstream part of the flow path is provided with a water structure changing part 4, which changes the water structure. 17 The spectrum value of O-NMR changes. The water structure change portion 4 is filled with ceramic particles 5. The filling is densely packed to enhance the resonance effect when colliding with flowing water.

[0057] As ceramic particles 5, the following particles are used: ceramic particles obtained by adding ash obtained by burning binchotan charcoal containing at least a large amount of iron minerals to a ceramic material mainly composed of silicon dioxide SiO2 and aluminum oxide Al2O3 and containing at least one of oxides of alkali metals, alkaline earth metals, and oxides of elements from the eighth to tenth groups, and granulating the resulting material.

[0058] The calcination temperature of Binchotan charcoal is preferably 1250° C. to 1330° C., and the addition ratio to the ceramic material is preferably 0.5% to 5% by weight. Binchotan charcoal ash is kneaded and granulated.

[0059] Ceramic particles obtained by mixing and granulating unfired binchotan powder instead of binchotan ash and ceramic particles obtained by mixing and granulating commercially available iron powder instead of binchotan ash cannot make water particles sufficiently small.

[0060] Not only can we add Binchotan, but we can also add the ash of Kibuki clay and granulate it. Kibuki clay is kaolinite (Al2Sl2O5(OH)4), which is a weathered product of granite, and is buried and deposited together with plants and driftwood in swamps. Compared with other minerals, it contains trace amounts of catalyst metals such as Ni and Pt in addition to organic matter, so it can be expected to be used 17 The changes in O-NMR spectrum values ​​indicate changes in the water structure.

[0061] A contraction portion 7 is provided on the downstream side of the water structure changing portion 4, and the downstream side of the contraction portion 7 is used as a micro-bubble generating portion 6. The micro-bubble generating portion 6 is a pressure opening portion that rapidly increases the volume, and generates micro-bubbles by cavitation.

[0062] In this embodiment, a nozzle 8 is provided in the outlet 3 of the pipe 1. The nozzle 8 is as shown in FIG. Figure 2 As shown, the downstream side is composed of an open cover portion 9 and a circular plate 10 installed on the upstream side of the cover portion 9, the circular plate 10 is formed with a plurality of circular holes 11, and the cover portion 9 is formed with a small hole 12 connecting the outside and the inside.

[0063] The water passing through the nozzle 8 collides with each other, and the bubbles generated by cavitation become smaller. Specifically, the diameter of the bubbles becomes less than 40 nm. In the above-described embodiment, the microbubbles are generated in two stages by the constriction portion 7 and the nozzle 8 .

[0064] Regarding the particle size of the microbubbles generated by the functional water manufacturing device of the present invention, a solution is prepared by adding DMPO (5,5-dimethyl-1-pyrroline N-oxide) as a spin scavenger, and the solution is measured by using an electron spin resonance device (ESR) by observing the spectrum of DMPO-OH as a spin adduct caused by the presence of nanobubbles.

[0065] Figure 3 It means that the structural change of the sample water is taken as 17 The results of the measurements using O-NMR spectra are shown in the table. Figure 4 Yes means Figure 3 Samples (1) and (5) 17 This is a graph showing measured O-NMR spectrum values.

[0066] Sample (1) is tap water, sample (2) is water obtained by immersing ceramic particles without adding binchotan ash in a container added with tap water for 1 hour, sample (3) is water obtained by immersing ceramic particles without adding binchotan ash before firing (raw binchotan) in a container added with tap water for 1 hour, sample (4) is the case where ceramic particles added with binchotan ash are filled in the cluster refinement part of the device of the present invention and tap water is flowed at a speed of 0.1 m / s, sample (5) is the case where tap water is flowed at a speed of 1.5 m / s, and sample (6) is the case where tap water is flowed at a speed of 2.0 m / s.

[0067] From sample (2), it can be seen that simply by bringing ceramic particles into contact with tap water, 17 The O-NMR spectrum value becomes smaller, that is, the water structure changes. From sample (3), it can be seen that when unfired binchotan charcoal is directly added to ceramic particles, the water structure change does not change significantly compared to the case of ceramic alone.

[0068] From sample (4), it can be seen that when tap water is brought into contact with ceramic particles to which binchotan ash is added at a speed of 0.1 m / s, compared with the case of immersion, 17 The O-NMR spectrum value becomes smaller. In addition, from samples (5) and (6), it can be seen that when the flow rate of tap water is increased, 17 The O-NMR spectrum value becomes smaller. It should be noted that in order to prevent water hammer, the speed of tap water is set to 2.0 m / s as the upper limit.

[0069] Figures 5 to 7 express Figure 3 The test results of the amount of n-hexane dissolved (permeation) in the sample water are shown.

[0070] Figure 5 of tap water is equivalent to Figure 3 Sample (1), Figure 6 The record is that ordinary water is equivalent to Figure 3 Sample (2), Figure 7 The record is that the water added with carbonic acid is equivalent to Figure 3 It should be noted that the addition of carbonic acid means that a trace amount of carbonic acid is added to remove impurities in water. 17 The O-NMR spectrum value was 73.0 Hz.

[0071] From this we can see that the change in the structure of water is represented by 17 The O-NMR spectrum value becomes smaller (1200 mg / L to 2800 g / L), while the solubility in n-hexane increases significantly.

[0072] Figure 8 and Fig. 9This is a comparative example (Day 1 and Day 15) of using tap water and the functional water of the present invention as water for vases. The left vase used functional water, and the right vase used tap water.

[0073] From the comparison of the photographs, it can be seen that the flower retention time is longer when the functional water of the present invention is used.
