As shown in FIGS. 4 to 6, the mist generator 46 is disposed in the spray nozzle device 45 (spray nozzle 48), and includes a mist throttle hole 52 and a guide body 53.

[0032] The mist restriction hole 52 is formed in the spray nozzle 48, as shown in Figures 4 to 6. The mist restriction hole 52 is disposed between the nozzle restriction hole 51 (spray nozzle 48) and the nozzle hole 49 (nozzle body 47). The mist restriction hole 52 is disposed concentrically with the nozzle restriction hole 51 and the nozzle hole 49. The mist restriction hole 52 opens at the other nozzle end 48B in the direction of the center line q of the spray nozzle 48, and communicates with the nozzle hole 49 (nozzle body 47). The mist restriction hole 52 gradually reduces in diameter from the nozzle hole 49 toward the nozzle restriction hole 51, and extends in the direction of the center line q of the spray nozzle 48. 4 to 6, the mist throttle hole 52 is formed as a conical hole (frusto-conical hole) whose diameter gradually decreases from the nozzle hole 49 (the other nozzle end 48B) toward the nozzle throttle hole 51 in the direction of the center line q of the spray nozzle 48.

Each liquid flow hole 56 is arranged at equal intervals in the circumferential direction of the guide disc 54. Each liquid flow hole 56 penetrates the guide disc 54 in the direction of the plate center line t of the guide disc 54. The guide disc 54 is formed with a disc diameter DB that is larger than the hole diameter dM of the mist throttle hole 52 and smaller than the hole diameter dG of the nozzle hole 49.

The first and second spiral surfaces 57, 58 intersect the cone side surface 55C and are disposed between the cone bottom plane 55B and the cone top surface 55A. The first and second spiral surfaces 57, 58 have a surface width Hp intersecting the cone side surface 55C and extend in a spiral shape between the cone bottom plane 55B and the cone top surface 55A. The surface width Hp of the first and second spiral surfaces 57, 58 gradually narrows (decreases) in the direction of the cone center line u of the mist guide 55 and extends in a spiral shape from the cone bottom plane 55B to the cone top surface 55A.

[0037] The mist guide 55 has a guide height: GL in the direction of the cone center line u as shown in Fig. 9. The guide height: GL is set to be approximately the same as or lower than the hole length: ML of the mist throttle hole 52. 7, the mist guide 55 has a maximum bottom width JH of the conical bottom plane 55B. The maximum bottom width JH is narrower than the hole diameter dM of the mist throttle hole 52 and the circular diameter DB of the guide disc .

The mist guide 55 and the guide disk 54 are formed integrally. As a result, the mist guide 55 is disposed so as to protrude from the plate surface 54A (one plate surface) of the guide disk 54 in the direction of the plate center line t (cone center line u) of the guide disk 54. The mist guide 55 is placed on the plate surface 54A of the guide disk 54 without blocking any of the liquid flow holes 56. Each liquid flow hole 56 is disposed around the periphery of the mist guide 55 and passes through the guide disc 54, as shown in Figures 7 and 9.

[0039] In the mist generator Y, the guide body 53 (guide disk 54 and mist guide 55) is incorporated into the spray nozzle 48 and the nozzle body 47, as shown in Figures 4 to 6.

The first and second mist flow paths δ1, δ2 are formed in such a way that the flow path width gradually narrows from the conical bottom plane 55B to the conical top surface 55A of the mist guide 55 in the direction of the cone center line u, as shown in FIG. 6. The flow path width of the first and second mist flow paths δ1, δ2 is the cross-sectional width defined by the conical inner circumferential surface 52A of the mist throttling hole 52, the first and second vortex flow surfaces 57, 58, and the conical side surface 55C of the mist guide 55. The first and second mist flow paths δ1, δ2 are connected to the nozzle hole 49 through the liquid flow holes 56.

The flow path pipe 65 is connected to the nozzle body 47 (mist generating device Y) by airtightly inserting one pipe end 65A of the flow path pipe 65 into the nozzle hole 49. The flow path pipe 65 is disposed concentrically with the nozzle hole 49, with the hole center line w of the flow path hole 66 coinciding (positioned) with the hole center line q of the nozzle hole 49 (center line q of the spray nozzle 48). The flow passage pipe 65 is inserted into the nozzle hole 49 with one pipe end 65A abutting against the plate rear surface 54B (the other plate surface) of the guide disk 54. As a result, the guide disk 54 (guide body 53) is clamped between the other nozzle end 48A (spray nozzle 48) of the spray nozzle 48 and one pipe end 65A (flow path pipe 65) of the flow path pipe 65, as shown in Figure 6, and is fixed to the nozzle main body 47 (spray nozzle 48).

The electrode reference plane 23 is formed at one cylindrical end 16A of one cylinder end 16 (cylindrical body), and opens to the sealed space S (facing the sealed space S or communicating with the sealed space S). As a result, the electrode reference plane 23 is exposed to the water (liquid) that fills (fills) the sealed space S, and is formed on one of the cylinder ends 16 so as to be exposed to the water (liquid) in the sealed space S.

[0067] The third electrode shaft 35 is formed in the same cross-sectional shape as the first electrode shaft 25, as shown in Figs. 15, 16 and 20. The third electrode shaft 35 is formed, for example, in a cylinder (round bar) with a circular cross-sectional shape. As shown in Fig. 20, the third electrode shaft 35 is formed in a cylinder (round bar) having a total shaft length L3 and a shaft diameter D1 shorter than those of the first electrode shaft 25.

The third electrode shaft 35 is disposed between an axial center line g of the third electrode shaft 35 and an axial center line f of the second electrode shaft 28 at an electrode interval EH. As a result, the first electrode shaft 25, the second electrode shaft 28, and the third electrode shaft 35 are arranged on a circle cr centered on the cylindrical center line a of the tank body 15, as shown in Figure 16, and are arranged with each axis center line e, f, g positioned at each vertex of an equilateral triangle.

[0069] 20 , the third electrode shaft 35 is disposed with one shaft end 35A side fixed to one cylinder end 16.

[0070] 15, 16, and 20, the third electrode shaft 35 is disposed such that its axial center line g is perpendicular to the electrode reference plane 23 and parallel to the cylinder center line a of the tank body 15. As shown in Fig. 20, the third electrode shaft 35 extends (projects) from the electrode reference plane 23 in the cylinder center line direction AL of the tank body 15 into the sealed space S with a second axial length L4. The third electrode shaft 35 extends from the electrode reference plane 23 into the sealed space S with a second axial length L4 that is shorter than the first axial length L2 of the first electrode shaft 25. The second axial length L3 of the third electrode shaft 35 is, for example, half the first axial length L2 of the first and second electrode shafts 25, 28 [L4=(L2) / 2].

[0071] 20, 21, and 23, the third electrode wire 36 is placed in the sealed space S and wound around the third electrode shaft 35. The third electrode wire 36 is formed, for example, in a circular cross section with the same wire diameter D1 as the first electrode wire 26. The third electrode wire 36 is made of a metal such as iron, copper, stainless steel, titanium, platinum, gold, iridium, palladium, etc. The third electrode wire 36 is made of the same metal as the third electrode shaft 35 (first electrode wire 26), for example, titanium.

[0072] 21 and 23, the third electrode wire 36 is wound around the third electrode shaft 35 in the direction of the axial center line g of the third electrode shaft 35. As shown in Fig. 21 and 23, the third electrode wire 36 is wound in a spiral shape around the third electrode shaft 35 (the outer circumferential surface 35a of the third electrode shaft) with a third winding length Lc and a third winding pitch Pc. As shown in Figures 21 and 23, the third electrode wire 36 is spirally wound around the third electrode shaft 35 between the other axial end 35B of the third electrode shaft 35 and the electrode reference plane 23, with a third winding length Lc and a third winding pitch Pc. 21 , the third winding length Lc of the third electrode wire 36 is a length (winding length) that is shorter than the first and second winding lengths La, Lb of the first and second electrode wires 26, 29. The third winding pitch Pc of the third electrode wire 36 is the same pitch (winding pitch) as the first winding pitch Pa of the first electrode wire 26.

[0073] 16, the first electrode 2 and the second electrode 3 are disposed in a sealed space S with an electrode gap GH between the first and second electrodes 2, 3. The first electrode 2 and the second electrode 3 are arranged in parallel with a first electrode wire 26 wound around a first electrode shaft 25 and a second electrode wire 29 wound around a second electrode shaft 28 with an electrode gap GH between them. The second electrode wire 29 is spirally wound around the second electrode shaft 28 with the electrode gap GH between the first electrode wire 26 wound around the first electrode shaft 25. 16, the first electrode 2 and the third electrode 4 are disposed in a sealed space S with an electrode gap GH between the first and third electrodes 2, 3.

The third electrode wire 36 is spirally wound around the third electrode shaft 35 with the electrode gap GH between the first electrode wire 26 wound around the first electrode shaft 25.

[0074] As shown in FIG. 24, the DC power supply 5 applies a DC voltage to the first electrode shaft 25 (first electrode 2), the second electrode shaft 28 (second electrode 3), and the third electrode shaft 35 (third electrode 4). The first electrode shaft 25 (first electrode 2), the second electrode shaft 28 (second electrode 3), and the third electrode shaft 35 (third electrode 4) are connected (electrically connected) to a DC power supply 5, and a DC voltage of the DC power supply 5 is applied to the first electrode shaft 25, the second electrode shaft 28, and the third electrode shaft 35.

[0075] As shown in FIG. 24, the polarity switching device 6 switches the polarity of the DC voltage applied to the first electrode shaft 25 (first electrode 2), the second electrode shaft 28 (second electrode 3), and the third electrode shaft 35 (third electrode 4). The polarity switching device 6 is connected (electrically connected) to the DC power supply 5, the first electrode 2, the second electrode 3, and the third electrode 4. The polarity switching device 6 is connected to one shaft end 25A of the first electrode shaft 25, one shaft end 28A of the second electrode shaft 28, and one shaft end 35A of the third electrode shaft 35. The polarity switching device 6 switches between first to third polarity modes (first to third polarity patterns). In the first polarity mode (first polarity pattern), a positive voltage (DC) is applied to the first electrode shaft 25 (first electrode 2) and the second electrode shaft 28 (second electrode 3), and a negative voltage (DC) is applied to the third electrode shaft 35 (third electrode 4). In the second polarity mode (second polarity pattern), a negative voltage is applied to the first electrode shaft 25 (first electrode 2) and the second electrode shaft 28 (second electrode 3), and a positive voltage (DC) is applied to the third electrode shaft 35 (third electrode 4). In the third polarity mode (third polarity pattern), a positive voltage (DC) is applied to the first electrode shaft 25 (first electrode 2), and a negative voltage is applied to the second electrode shaft 28 (second electrode 3) without applying a DC voltage to the third electrode shaft 35 (third electrode 4).

[0076] 24, the switching operation device 7 is connected (electrically connected) to the polarity switching device 6. The switching operation device 7 has a plurality of switching buttons 81, 82, 83 (switching operation section). Each of the switching buttons 81, 82, 83 is connected to the polarity switching device 6. The switching operation device 7 outputs a weak acid signal (weak acid command) to the polarity switching device 6 based on the operation of a switching button 81 (weak acid switching section). The switching operation device 7 outputs a neutral signal (neutral command) to the polarity switching device 6 based on the operation of a switching button 82 (neutral switching section). The switching operation device 7 outputs a weak alkaline signal (weak alkaline command) to the polarity switching device 6 based on the operation of the switching button 83 (weak alkaline switching section).

[0077] Based on the input of a weak acidic signal, a neutral signal, and a weak alkaline signal, the polarity switching device 6 applies a positive voltage (DC) to the first and second electrode axes 25, 28 and a negative voltage to the third electrode axis 35 (first polarity mode), or applies a negative voltage to the first and second electrode axes 25, 28 and a positive voltage to the third electrode axis 35 (second polarity mode), or applies a positive voltage to the first electrode axis 25 and a negative voltage to the second electrode axis 28 (third polarity mode).

[0078] 1, the water supply pump 71 is connected to a water source (not shown) and an inlet pipe 72. The water supply pump 71 draws in water and air from the water source and discharges water (pressurized water) and air to the inlet pipe 72 (inlet channel). The water supply pump 71 is connected to the electrolysis device X (inlet 19) through the inlet pipe 72 (inlet channel).

[0079] 17 and 20, the electrolysis device X is disposed such that the other cylindrical end portion 17 of the electrolysis tank 1 faces upward. The electrolysis device X is connected to the mist generator Y through a flow path pipe 65 (flow path hole 66) and to the water supply pump 71 through an inlet pipe 72. The electrolysis device X is connected to the flow path pipe 65 by airtightly inserting the outflow boss 22 into the other pipe end 65B side (flow path hole 66) of the flow path pipe 65. As a result, the outlet 20 is connected to the mist generation device Y through the outlet boss 22 and the flow path pipe 65 (flow path hole 66), and the mist generation device Y communicates with the sealed space S.

[0080] As shown in FIG. 1, the electrolysis device Y has an inlet boss 21 connected to an inlet pipe 72 and communicated with a water supply pump 71 . As a result, the inlet 19 is connected to the water supply pump 71 through the inlet boss 21 and the inlet pipe 72, and the water supply pump 71 communicates with the sealed space S.

[0081] 1, the mist generating system SY drives a water supply pump 71. The water supply pump 71 draws water from a water source and discharges the water (pressurized water) and air to an inlet pipe 72. The water (pressurized water containing air) discharged to the inlet pipe 72 flows through the inlet pipe 72 and flows into the inlet 19 of the electrolysis device X.

[0082] In the electrolysis device X, water that has flowed into the inlet 19 flows into the sealed space S of the electrolysis tank 1, as shown in Figures 17 and 20. The sealed space S of the electrolysis tank 1 is filled with water. When the sealed space S of the electrolytic tank 1 is filled with water, the water (liquid) flowing from the inlet 19 into the sealed space S mainly flows between the other shaft ends 25B, 28B of the first and second electrode shafts 25, 28 and the other cylindrical end 17, and flows out from the outlet 20 into the flow path pipe 65 (flow path hole 66). This allows the electrolysis tank 1 to temporarily retain water (liquid) in the sealed space S between the outlet 20 and one of the cylinder ends 16 in the cylinder center line direction AL of the tank body 15. The first electrode 2 (first electrode shaft 25, first electrode wire 26 wound around the first electrode shaft 25), the second electrode 3 (second electrode shaft 28, second electrode wire 29 wound around the second electrode shaft 28), and the third electrode 4 (third electrode shaft 35, third electrode wire 36 wound around the third electrode shaft 35) are immersed in water that fills (fills) the sealed space S.

[0083] The switching operation device 7 outputs a weak acid signal to the polarity switching device 6 based on the operation of a switching button 81, as shown in FIG. As shown in FIG. 24, when a weak acid signal is input, the polarity switching device 6 applies a positive voltage (DC) to the first electrode axis 25 (first electrode 2) and the second electrode axis 28 (second electrode 3), and applies a negative voltage (DC) to the third electrode axis 35 (third electrode 4). As a result, oxygen is generated on the first electrode shaft 25, the first electrode wire 26 wound around the first electrode shaft 25, the second electrode shaft 28, and the second electrode wire 29 wound around the second electrode shaft 28, and hydrogen is generated on the third electrode shaft 35 and the third electrode wire 36 wound around the third electrode shaft 35. Since the surface areas of the first electrode 2 and the second electrode 3 are greater than the surface area of ​​the third electrode 4, a larger amount of oxygen is generated compared to the amount of hydrogen generated. The oxygen and hydrogen generated by the electrolysis of water are dissolved in the water or flow out in the form of gas (air bubbles) from the outlet 20 to the flow path pipe 65 (flow path hole 66) together with the water and air. In the electrolysis tank 1, the water in the sealed space S and the water flowing out from the outlet 20 become weakly acidic water.

[0084] The switching operation device 7 outputs a neutral signal to the polarity switching device 6 based on the operation of the switching button 82, as shown in FIG. As shown in FIG. 24, when a neutral signal is input, the polarity switching device 6 applies a positive voltage (DC) to the first electrode axis 25 (first electrode 2) and applies a negative voltage (DC) to the second electrode axis 28 (second electrode 3). As a result, oxygen is generated on the first electrode shaft 25 and the first electrode wire 26 wound around the first electrode shaft 25, and hydrogen is generated on the second electrode shaft 28 and the second electrode wire 29 wound around the second electrode shaft 28. Since the surface area of ​​the first electrode 2 and the surface area of ​​the second electrode 3 are the same, the amounts of oxygen and hydrogen generated are approximately the same. The oxygen and hydrogen generated by the electrolysis of water are dissolved in the water or flow out in the form of gas (air bubbles) from the outlet 20 to the flow path pipe 65 (flow path hole 66) together with the water and air. In the electrolysis tank 1, the water in the sealed space S and the water flowing out from the outlet 20 become neutral water.

[0085] The switching operation device 7 outputs a weak alkaline signal to the polarity switching device 6 based on the operation of the switching button 83, as shown in FIG. As shown in FIG. 24, when a weak alkaline signal is input, the polarity switching device 6 applies a negative voltage (DC) to the first electrode axis 25 (first electrode 2) and the second electrode axis 28 (second electrode 3), and applies a positive voltage (DC) to the third electrode axis 35 (third electrode 4). As a result, hydrogen is generated on the first electrode shaft 25, the first electrode wire 26 wound around the first electrode shaft 25, the second electrode shaft 28, and the second electrode wire 29 wound around the second electrode shaft 28, and oxygen is generated on the third electrode shaft 35 and the third electrode wire 36 wound around the third electrode shaft 35. Since the surface areas of the first electrode 2 and the second electrode 3 are greater than the surface area of ​​the third electrode 4, a larger amount of hydrogen is generated compared to the amount of oxygen generated. The oxygen and hydrogen generated by the electrolysis of water are dissolved in the water or flow out in the form of gas (air bubbles) from the outlet 20 to the flow path pipe 65 (flow path hole 66) together with the water and air. In the electrolysis tank 1, the water in the sealed space S and the water flowing out from the outlet 20 become weakly alkaline water.

[0086] In this way, in the electrolysis device X, the first to third electrode wires 26, 28, 36 are spirally wound around the first to third electrode shafts 25, 28, 35 to increase the surface area of ​​the electrodes, so that a large amount of gas (hydrogen, oxygen) can be stably generated by electrolysis of water, and water containing gas (hydrogen, oxygen, air) can be stably discharged into the flow pipe 65 (mist generation device Y). The electrolysis device X1 electrolyzes water in the sealed space S of the electrolysis tank 1, and therefore all of the gases (hydrogen, oxygen), water, and air generated by the electrolysis of water can be discharged to the flow pipe 65 (mist generating device Y) without releasing (discharging) the hydrogen, oxygen, and air generated by the electrolysis of water into the outside air.

[0087] The water and gas (hydrogen, oxygen, air / hydrogen, oxygen, air bubbles) flowing out from the outlet 20 of the electrolysis device X flows through the flow passage pipe 65 (flow passage hole 66) and into the mist generation device Y, as shown in Figs. 1 and 4.

[0088] In the mist generating device Y, water (liquid) and gas (hydrogen, oxygen, air) flow from a flow passage pipe 65 through each liquid flow hole 56 of a guide disk 54 and into a mist throttle hole 52 as shown in FIG.

[0089] The water and gas (hydrogen, oxygen, air) that flow into the mist throttling hole 52 flows through the first and second spiral mist flow paths δ1, δ2, as shown in Figure 6, and is discharged (sprayed) into the mist throttling hole 52, and then passes through the mist throttling hole 52 and the nozzle throttling hole 51, and is sprayed from the spray nozzle 48 as mist-like water droplets to the outside of the mist generating device Y (spray nozzle 48).

[0090] As water and gas (hydrogen, oxygen, air) flow through the first and second spiral mist flow paths δ1, δ2 from the conical bottom plane 55B of the mist guide 55 toward the conical top surface 55A, as shown in Figure 6, the flow velocity gradually increases and the pressure is gradually reduced, and the water and gas are sprayed into the mist restriction hole 52 of the mixing gap MX (inside the mist restriction hole 52 between the conical top surface 55A and the nozzle restriction hole 51). As a result, the water and gas (hydrogen, oxygen, air) injected from the first and second mist flow paths δ1, δ2 into the mist throttling hole 52 of the mixing gap MX becomes a high-pressure turbulent flow (vortex flow, swirling flow) in the mist throttling hole 52 of the mixing gap MX.

[0091] As shown in FIG. 6, the first and second spiral mist flow paths δ1, δ2 inject water and gas (hydrogen, oxygen, air) from the conical upper surface 55A of the mist guide 55 along the conical inner surface 52A of the mist throttling hole 52 of the mixing gap MX. As a result, the first and second spiral mist flow paths δ1, δ2 and the conical inner surface 52A of the mist throttling hole 52 of the mixing gap MX form (generate) a vortex (swirling flow) around the hole center line q of the mist throttling hole 52 in the mist throttling hole 52 of the mixing gap MX.

[0092] When mist-like water droplets are sprayed from the nozzle throttling hole 51 (mist throttling hole 52) to the outside of the mist generating device Y (spray nozzle 48), a negative pressure state is created on the outlet side (the side where the mist-like water droplets are sprayed) of the nozzle throttling hole 51 (mist throttling hole 52). By creating a negative pressure state on the outlet side of the nozzle throttling hole 51, the high-pressure and turbulent (vortex, swirling) water and gas (hydrogen, oxygen, air) sprayed from the first and second mist flow paths δ1, δ2 into the mist throttling hole 52 of the mixing gap MX pass through the outlet part of the mist throttling hole 52, causing bubbles to precipitate due to the reduced pressure, and the gas (hydrogen, oxygen, air) together with the air entrained during spraying is crushed (sheared) by the turbulent flow, turning into mist-like water droplets mixed with and dissolved in micro-bubbles (microbubbles of hydrogen, oxygen, and air) and nano-bubbles (ultrafine bubbles of hydrogen, oxygen, and air). The mist-like water droplets mixed with and containing microbubbles (micron-sized bubbles of hydrogen, oxygen, and air) and ultrafine bubbles (nano-sized bubbles of hydrogen, oxygen, and air) pass through the mist throttle hole 52 and are sprayed out of the mist generating device Y from the nozzle throttle hole 51 of the spray nozzle 48, as shown in FIG. 6.

[0093] In the mist generating system SY, the mist generator Y sprays weakly acidic water droplets (droplets) containing and dissolved in micro- and ultra-fine bubbles of hydrogen, oxygen, and air, or neutral water droplets (droplets) containing and dissolved in micro- and ultra-fine bubbles of hydrogen, oxygen, and air, or weakly alkaline water droplets (droplets) containing and dissolved in micro- and ultra-fine bubbles of hydrogen, oxygen, and air. [Industrial Applicability]

[0094] The present invention is ideal for generating mist-like water droplets containing mixed and intermixed air bubbles from water and gas. [Explanation of symbols]
