Abstract

PROBLEM TO BE SOLVED: To produce low-cost high-quality modified water applicable to various uses at a low energy consumption in a short time by installing a mixing means for mixing water with a surfactant, a liquid transport means for causing a mixed fluid to flow, and a magnetic field application means for applying, to the fluid, a magnetic field in the direction crossing to the flow direction of the fluid. SOLUTION: In producing modified water by using a modified water production apparatus, when raw water to be treated is put in a water storage tank 1 and a circulation pump 2 is driven, the raw water flows through a minute eddy current generation apparatus 3 and a magnetic field application apparatus 4 and returns to the water storage tank 1. The magnetic field application apparatus 4 has a magnet arranged in the vicinity of a pipe forming a channel for the circulated water and generates such a magnetic field as to form lines of magnetic force in the direction crossing to the flow of the circulated water. When water passes through the magnetic field, a magnetic field is generated in the direction vertical to both the flow direction and the lines of magnetic force. Since water molecule clusters are electrified by this magnetic field and are given kinetic energy in the direction of this magnetic field, the collision among the water molecule clusters becomes violent, forming finer clusters.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic front view showing an apparatus for producing reformed water according to a first embodiment of the present invention, and FIG. 2 is a flow chart showing the apparatus for producing reformed water. As shown in FIG. 1, the apparatus for producing reformed water of the embodiment includes a water storage tank 1 mounted on a common gantry 8, a high-pressure circulation pump 2 for circulating water in the water storage tank 1 through a valve, and a fine circulating water. The fine eddy current generator 3 that generates the eddy current, and further, by the magnetic force and the quartz action,
It comprises a magnetic field applying device 4 for adding a charge to the circulating water and a control panel 6 with a built-in inverter for adjusting the pump pressure based on the output of a pressure detecting device (not shown).

In the case of producing reformed water using the reformed water producing apparatus configured as described above, when the raw water to be treated is put into the water storage tank 1 and the circulation pump 2 is driven, the raw water generates fine eddy currents. After passing through the device 3 and the magnetic field applying device 4, it returns to the water storage tank 1 again.

As shown in FIG. 5, the fine eddy current generator 3 comprises one or a plurality of fine hole perforated plates 20 having a large number of fine holes (diameter of about 0.5 to 1 mm). By passing through the microperforated plate 20, it is emitted as a turbulent jet having a fine vortex structure. At this time, the huge cluster of water molecules is broken into small clusters by turbulence. A similar effect can be obtained by vibrating the fluid using ultrasonic waves.

Further, as shown in FIG. 6 (a), the fine eddy current generator 3 may have a configuration in which a rotating blade 23a having a twist or a cylindrical member 22a provided with 23a is housed in a casing 21. A plurality of fixed blades 23a having the same twist direction are arranged.

Alternatively, the fine eddy current generator 3 shown in FIG.
As shown in (b), a configuration in which a fixed blade 23b having a twist on the surface or a cylindrical member 22b in which 23b is implanted may be stored in the casing 21. Fixed blade 2
As for 3b, the direction in which the twist direction is opposite is arranged alternately.
Water is discharged as a turbulent jet having a fine vortex structure by passing through the rotating blade 23a or the fixed blade 23b.

As shown in FIG. 3, the magnetic field applying device 4 is provided with a magnet 4c (or an electromagnet) close to a pipe 4a forming a circulating water flow path. Magnetic field is generated. As water passes through this magnetic field, an electric field is generated perpendicular to the direction of flow and the direction of the lines of magnetic force. The water molecule cluster is charged by this electric field, and kinetic energy in the direction of the electric field is applied.
The collision of water molecule clusters becomes active, and the clusters become finer and finer. The periphery of the pipe 4a and the magnet 4c is covered with a nonmagnetic magnetic shield 4d (closed circuit coil).

As described above, in the magnetic field applying device 4, charged very fine water molecule clusters are generated. Quartz (crystal grains) to further enhance the effect of the magnetic field applying device 4
It is effective to use. The inlet of the circulating water of the pipe 4a is expanded, and a crystal ball 4b having a diameter of about 5 mm connected in a bead shape is installed therein, thereby further improving the miniaturization efficiency of the water molecule cluster. This is considered that the natural frequency of the crystal contributes to the miniaturization of the cluster.

Further, as shown in FIG. 4, the same effect can be obtained even when the magnetic field applying device 4 in which a large number of quartz particles 4b are packed in a mesh container 4e is installed in the magnetic field of the magnet 4c.

Furthermore, it is effective to include a large amount of dissolved oxygen in the circulating water as a means for enhancing the effect of the magnetic field applying device. This is made possible by installing an oxygen or air supply device in the circulation channel. The air supply device 9 shown in FIG. 1 is provided with a venturi pipe 4 in a circulation flow path as shown in FIG. 7, an air / oxygen injection pipe 25 is connected to a venturi pipe 24, and this is connected to an atmosphere opening pipe via a valve. The air is sucked by the pressure reduced by the flow rate of the circulating water.

As described above, the raw water to be treated exits the water storage circulation tank, passes through the fine eddy current generator, and further passes through the magnetic field application device, and returns to the water storage circulation tank again.
When this water circulation circuit is continuously operated, the water molecule clusters are miniaturized, and the charge density in water is dramatically increased.
As a result, the PH value of water in the water storage tank gradually increases,
Eventually, it will settle to a value of about PH value 9.

The operation time until the pH value is reached is about 5 minutes, and it is possible to produce stable alkaline ionized water in a very short time. Water P in water storage tank 1
The H value is measured by an oxidation-reduction potentiometer 7 provided in the water storage tank 1.

If this alkaline ionized water is left,
Although it is gradually neutralized, it is effective to add a small amount of an activity adjuvant (surfactant) as a method for maintaining alkaline properties for a long time. For example, adding about 0.1% by volume of a plant-based active adjuvant (consisting of several food additives) to raw water and producing alkaline ionized water using this device will result in a long term of more than one year. The PH value can be maintained.

At this time, the surfactant functions as a large amount of charge supply source and functions to greatly increase the charge density in the alkaline ionized water. The surfactant is supplied from a surfactant tank 5 connected to a circulating water channel via a valve.

The reformed water thus produced is sent to the alkaline ionized water storage tank 11 by the pump 10 and stored therein. This reformed water has the same action as cell water of animals and plants, and effectively acts on growth and resuscitation. In addition, it has been reported as a clinical example that the amount of SOD enzyme that suppresses active oxygen harmful to the body is increased and that it is also effective for anticancer action. In the field of industrial chemistry, since the surface tension of the reformed water is reduced, it can be used as cleaning water for products and parts as a pollution-free oil decomposition cleaning agent.

The water was supplied to a household water tap via an alkaline ionized water storage tank 11 and used as drinking water. After several weeks of drinking, atopic dermatitis was improved and hypertension was reduced, which had a remarkable effect on health promotion.

As an effective use of the present apparatus and the present method in the energy field, there is production of a mixed fuel (emulsion fuel) of petroleum fuel and water. The conventional method of producing an emulsion fuel is a method of mixing a fuel, water and a small amount of a surfactant, and producing the emulsion fuel by physical stirring. However, the emulsion produced by this method has a problem that water and fuel are separated in a short time. This is considered to be because the cluster of water molecules remains in a huge state and is not miniaturized, so that the charge density in the emulsion is also extremely low and recombination proceeds in a short time. Further, when the emulsion fuel produced by the conventional technique is burned, the water mixing ratio of the fuel is 20%.
Above, there is a loss of evaporation heat of 5% or more, and there is a problem in terms of combustion efficiency.

The present invention also solves the above problem. A method for producing an emulsion fuel according to a second embodiment of the present invention will be described with reference to FIG. Fuel and water are supplied from the water tank 12 and the fuel tank 13 to the pre-mixing tank 14 via the respective valves, and the mixture is removed by the pump 15 from the reforming water producing apparatus of the first embodiment except for the air supplying apparatus 9. And supplied to the reformed water production equipment. Then, the emulsion fuel produced by the reforming water producing device is stored in the emulsion fuel tank 17 by the pump 16 and further supplied to the diesel engine 18 by the pump 19. Water and fuel (light oil)
Were introduced into the reformed water production apparatus according to the present invention in equal amounts to produce an emulsion fuel having a mixing ratio of 1: 1. Thus, water and fuel (heavy oil, light oil,
If any fuel such as kerosene or gasoline can be used) and a small amount of a surfactant, and the apparatus is operated, a milky emulsion fuel is generated after a few minutes.

The molecular clusters of water and fuel pass through a fine eddy current generator and a magnetic field applying device, and are miniaturized and micelle-emulsified into a charged colloid. Surfactants play an important role in micelle formation. Surfactants have both a hydrophilic part and a lipophilic (hydrophobic) part in the molecule, and when dissolved in water, turn the hydrophilic group out and the lipophilic group inward, confine the oil molecules inside and the outside To form aggregates (micelles) formed by assembling a large number of ultrafine water molecule clusters. At this time, since the water molecules forming the outside of the micelle and the water molecules forming the outside of the other micelles are charged to the same polarity, the micelles repel each other and are extremely fine for an extremely long time (thousands of hours). The micellar structure can be maintained. When this new fuel is burned by the combustion device, the water molecule cluster explosively evaporates prior to the combustion of the central fuel cluster, so that the fuel cluster is further subdivided and the mixing state of fuel and air is improved. Since the heat of vaporization is taken, the maximum combustion temperature drops. Further, with the explosive evaporation of the water cluster, active hydrogen having a strong reducing action is formed, so that generation of nitrogen oxides is suppressed.

Further, using the present apparatus, kerosene and water are mixed in a ratio of 1:
As a result of making an emulsion fuel mixed with No. 1 and conducting a combustion experiment using a burner, the combustion efficiency was improved by about 30% due to improved mixing of fuel and air. In addition, clean combustion without soot generation was possible with an air amount of 以下 or less of the theoretical combustion air amount. When an emulsion fuel is produced by the method according to the invention,-carbon oxides, nitrogen oxides,
The generation of air pollutants such as soot can be significantly reduced.

This emulsion fuel was supplied to a diesel engine of 300 horsepower, and N
The emission of 0x was measured. As a result, there was a 60% or more reduction effect on the NOx emission when using pure fuel at a water mixing ratio of 40%. No soot was detected. Furthermore, as a result of measuring the fuel consumption rate at the time of rated output, it was found that the consumption of light oil could be reduced by 2 to 3%. FIG. 9 shows the result of measuring the NOx emission amount while changing the mixing ratio of water.

Further, a 1: 1 mixed emulsion fuel of water and kerosene was produced using the present apparatus, and a combustion experiment was carried out with a burner. As a result, high-temperature combustion at a combustion temperature of 1300 ° C. or higher was achieved, and no soot was generated. I was not seen.

The controller 28 controls the flow rates of the water in the water tank 12, the fuel in the fuel tank 13, and the surfactant in the surfactant tank 5, that is, the mixing ratio. The output signal (throttle opening signal) of the diesel engine 18 is input to the controller 28 to control the supply amount and the mixing ratio of the emulsion fuel. In the flow rate control, the opening degree of each control valve is controlled so that a signal indicating the set flow rate is output from each flow meter 26. Even with such an emulsion fuel manufacturing apparatus, an emulsion fuel capable of greatly reducing the generation of air pollutants can be manufactured.
