Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ion generating method and an ion generating apparatus, and more particularly to an ion generating method and apparatus capable of generating a high reduction potential negative ion and a high oxidation potential positive ion at high density. It is a thing.

[0002]

2. Description of the Related Art At present, the environment directly related to daily life such as air and water is significantly polluted, and it is feared that the health damage associated therewith will be enormous if not only actual damage but also potential damage is added. ing. For this reason, a wide variety of water purifiers and air purifiers are being actively used as a means of coping with daily life.

The pollution of air and water is mainly caused by soot and waste water discharged in accordance with industrial activities, volatilization and elution of discarded chemical substances, exhaust gas of automobiles and the like. Since the degree of pollution of air and water due to these can be easily grasped by measuring the oxidation potential, it is desired to achieve sufficient reduction as a countermeasure against this.
Negative ions are drawing attention as one of the concrete means.

In the meantime, as a means for generating negative ions, it has been adopted to apply a high voltage between the two electrodes to dissociate water molecules. However, air has a high insulating property and a high density of negative ions is generated. When a high voltage is applied, ozone is generated along with the occurrence of corona discharge, and negative ions at a certain angle are also lost, so that the danger of residual ozone is expected. Furthermore, there are some prior applications related to negative ion air cleaners and some of them have been put on the market, but these are simply a negative high potential added to the discharge pole needle that comes into contact with air. Therefore, the negative ion is poorly released into the air, which has a high insulating property, and in order to achieve a high release, even if a high voltage is applied, only the vicinity of the release electrode is charged by the negative ion and the release property is hindered. In a negative ion air cleaner, the ion emission density is at most 2000 to 3000.
It is about the number of pieces / cc, and in combination with the short-time life of negative ions, it has not been possible to raise the reduction potential in the building space to achieve cleaning.

On the other hand, in order to solve the environmental pollution, on the one hand, it is necessary not only to purify the already contaminated air and water, but also to deal with the source of waste water and smoke or the source of waste in industrial activities and daily activities. Although required, about half of the waste is considered to be sludge generated from wastewater treatment, and this wastewater treatment is preceded by biochemical treatment.
Use of a chemical neutralizing agent for adjusting the H value, a chemical flocculant for flotation or sedimentation separation of frog after biochemical treatment, or a chemical disinfectant for sterilization at the time of discharge after treatment. It is used in an extremely large amount, and most of this sludge is discarded and landfilled, and is still a cause of diffusion of environmental pollution.

On the other hand, negative ions for purifying contaminated air or for reducing and purifying contaminated water or positive ions for sterilizing various fungi in water are water molecules H ⁺ ions and OH ⁻ ions. Dissociate into H ₃ O
₂ and H ₃ O are defined as short-lived recombination states. Then, negative ions with high reduction potential are generated and released at high density, or positive ions with high oxidation potential are generated and released at high density, which promotes dissociation of water molecules and cleans air and sterilizes water. The result can be efficiently achieved.

To this end, water molecules in the air or water are made to have a low cluster by electric shock, and the water molecules are effectively resonantly excited to efficiently dissociate, so that a high negative potential or a high positive potential is obtained. Moreover, it is required to add a high DC pulse to the emission electrode,
In particular, when the insulating property such as air is high, the vicinity of the emitting electrode is overcharged, the releasing property of ions is hindered, and the risk of sparking is caused.

[0008]

That is, the present invention is directed to cleaning of contaminated air and chemical agents by stably releasing negative ions of high density at high reduction potential or positive ions of high density at high oxidation potential. An object of the present invention is to provide an ion generating method and an apparatus therefor capable of significantly reducing wastewater treatment.

[0009]

[Means for Solving the Problems] The technical means used by the present invention to solve the above-mentioned problems are to reduce the water molecules in the air and the water molecules in the sewage in the treatment of sewage.
In addition, the water molecules are efficiently dissociated to form H ⁺ ions and OH ⁻ ions, and negative ions with high reduction potential or positive ions with high oxidation potential are generated at high density. Therefore, the voltage is appropriately set in the range of 3000 to 30,000 V. Moreover, by adding a negative high voltage DC pulse and a positive high voltage DC pulse having a substantial pulse number of 0.5 to 50 kilopulses / second to the emission electrode, high density is achieved while reducing excessive charging near the emission electrode. Need to be released.

Therefore, the primary side of the high frequency output transformer consisting of a pair is input with a required high frequency by using a cycle changer whose frequency can be converted into a high frequency in the range of 1 to 100 kHz. At this time, one of the primary sides is grounded. The output voltage of the secondary side of the pair of high frequency output transformers is 30
It is designed to output from 00 to 30000V, and one side is grounded via a rectifier, and the other side is a negative high voltage due to a DC pulse of 0.5 to 50 kilopulses / second due to half-wave rectification. It is designed to be output as a DC pulse.

Further, the secondary side of the other high-frequency output transformer is also designed so that the output voltage thereof is 3000 to 30,000 V, and one side thereof is grounded via a rectifier so that the other side is substantially half-wave rectified. Specifically, a DC pulse of 0.5 to 50 kilopulses / second is output as a plus high voltage DC pulse of plus high voltage. Further, a variable switch is provided which is connected to the minus high voltage DC pulse output side and the plus high voltage DC pulse output side of the pair of secondary sides so as to adjust to an appropriate voltage according to usage conditions.

The minus high-voltage DC pulse and the plus high-voltage DC pulse adjusted to a desired voltage by the variable switch and output are then input to a pair of switching converters. This switching converter discharges negative ions or positive ions emitted from the emission electrode at a high density without overcharging. Therefore, when adding a negative high voltage DC pulse, a positive high voltage DC pulse is 1/20 to 1 / Conversion is mixed and added intermittently at a ratio of 100, or negative high voltage DC pulse is intermittently added at a ratio of 1/20 to 1/100 when a positive high voltage DC pulse is added. The switching function and the polarity conversion function are retained so that the conversion can be mixed and added to.

Thus, the outputs of the negative high-voltage DC pulse and the positive high-voltage DC pulse, which are intermittently converted and mixed by the switching converter, are added to the emission electrode through the changeover switch, whereby high reduction potential negative ions or It exists in a structure that releases high oxidation potential positive ions at high density.

[0014]

The present invention has the following actions because it has such a configuration. That is, the primary side of the pair of high frequency output transformers is input with a high frequency alternating current of 1 to 100 kHz, so that the secondary side output is also 1
To a high frequency of 100 kHz, and the output voltage is 30
The output voltage is in the range of 00 to 30000V, and one side of the secondary side of the high-frequency output transformer is grounded via a rectifier and rectified so that the other side has a negative high voltage. It is output as a high-voltage DC pulse that has been half-wave rectified, and the other side of the high-frequency output transformer is also grounded via a rectifier to the other side, resulting in a positive high voltage. By rectifying in this way, the other side is outputted with a positive high voltage and a high pulse of a half-wave rectified direct current.

Further, since a variable switch is provided on the secondary side output side of the pair of high frequency output transformers, the output voltage of the high frequency output transformers is 3000 to 3000.
Each can be output with an appropriate voltage in the range of 0V. The negative high-voltage DC pulse and the positive high-voltage DC pulse output via each variable switch are input to a pair of switching converters. The positive high-voltage DC pulse is intermittently converted and mixed at a ratio of 1/20 to 1/100 and output, and the other switching converter outputs the negative high-voltage DC pulse to the positive high-voltage DC pulse. Since the conversion is mixed and output intermittently at a ratio of 1/20 to 1/100 and is then added to the emission electrode via the changeover switch, a high reduction potential negative ion or a high oxidation potential positive ion is charged from the emission electrode. It is released at a high density without being hindered, and it has a high reduction potential minus the negative value as in wastewater treatment. It can be released at the same time also in the case of requiring emissions and high oxidation potential positive ions.

Embodiments of the present invention will be described below with reference to the drawings of the ion generator of the present invention. FIG. 1 is a principle explanatory diagram of the ion generator, and FIG. 2 is a principle explanatory diagram of a switching converter. Its frequency is 1 to 10 as the primary input
Since a high-frequency alternating current of 0 KHz is required, the cycle changer 1 is used to convert the frequency into the range of 1 to 100 kHz when using a general AC power source. When using a battery, a dry cell, or the like as a power source, it is possible to use an inverter (not shown) that can convert direct current into a proper frequency instead of the cycle changer 1. In such a case, the specific high frequency at the primary input is determined by the purpose of use and the conditions of use, but a high reduction potential for cleaning the air. The number is preferably about 30 to 50 kilopulses, or about 20 to 4 for separating organic substances and water molecules, reducing the clusters of water molecules, or promoting the dissociation of water molecules in wastewater treatment.
Since about 0 kilopulse is desired, the high frequency of the primary input for this purpose is about 40 to 100 kiloHz.
Is required.

The primary side input of the high frequency thus constructed is composed of a pair of high frequency output transformers 2 and 20 of the primary side 2A,
One side of 20A is grounded and input. The high frequency output transformers 2 and 20 are used in a pair so that one high frequency output transformer 2 outputs a negative high voltage DC pulse for releasing high reduction potential negative ions, and the other high frequency output transformer 2 is used. In No. 20, the reason is to output the positive high voltage DC pulse for releasing the high oxidation potential positive ions.

Therefore, one side 2C of the secondary side 2B of the high frequency output transformer 2 is grounded via the rectifier 2E,
It is considered that the other side 2D is held at a negative potential, and the output voltage of the secondary side 2B is 3000 to 3
It is designed to output in the range of 0000V. Further, the secondary side 20B of the other high-frequency output transformer 20 is grounded to one side 20C of the secondary side 20B via a rectifier 20E, and the other side 20D is considered to be held at a positive potential.
Also, the output voltage of the secondary side 20B is 3000 to 300.
It is designed to output in the range of 00V. The high frequency output transformers 2 and 20 use a high frequency alternating current ranging from at least 1 kHz to 100 kHz, so that a material having a high magnetic permeability at a high frequency is desired as a yoke material, and a ferrite or spinel type made of ferrimagnetic oxide is desired. Ferrite is preferred.

In addition, a negative voltage or a positive voltage is applied to the secondary side 2B, 20B of the high frequency output transformer 2, 20 in a range of 3000 to 30,000 depending on the purpose of use and the conditions of use.
Variable switch 3 to output at an appropriate voltage within the V range
A and 3B are provided. One of the variable switches 3A and 3B has a rectifier 2E provided on one side of the secondary side 2B of the high frequency output transformer.
As a result of being half-wave rectified by the
0 to 30000V and the pulse number is 0.5 to 50
It is output as a DC pulse of kilopulses / second, and the variable switch 3B further has a secondary side 20 of the high frequency output transformer 20.
Half-wave rectification is performed by the rectifier 20E provided on the one side of B, and the voltage is output as a DC pulse having a voltage of plus 3000 to 30000 V and a pulse number of 0.5 to 50 kilopulses / second.

The minus high voltage DC pulse and the plus high voltage DC pulse output from the variable switches 3A and 3B are further paired with the switching converters 4A and 4B.
Are input respectively. The switching converters 4A and 4B have a negative high-voltage DC pulse added to the emission electrode 6 to release the high reducing potential negative ions and a positive high voltage applied to the emission electrode 6 to release the high oxidation potential positive ions. Differentiation from DC pulse, and prevention of generation of sparks due to excessive charging in the vicinity of the emission electrode 6 due to emission of high reduction potential negative ions or high oxidation potential positive ions from the emission electrode 6, and prevention of inhibition of ion emission. From the above, when adding the negative high voltage DC pulse to the emission electrode 6, the positive high voltage DC pulse is converted and added at a ratio of 1/20 to 1/100 with respect to the negative high voltage DC pulse. It has a switching function and a polarity conversion function so that when adding a positive high voltage DC pulse to the emission pole 6, To positive high voltage direct current pulses it is intended to be added the proportion of 1/20 to 1/100 converted mix negative high voltage direct current pulses I following. Further, the voltage of the positive high-voltage DC pulse or the voltage of the negative high-voltage DC pulse that is intermittently converted and mixed is approximately 1/2 to 2/3 of the voltage of the main negative high-voltage DC pulse or the positive high-voltage DC pulse. desirable.

The switching converters 4A and 4B are not particularly limited and can be used as long as they have a switching function and a polarity converting function. The principle will be described with reference to FIG. 1 / to the switch driver 41B of the relay 41A of the converter 41
The drive signal is generated intermittently in the range of 20 to 1/100, and the relay 41 is generated by the drive signal.
The contact 41C of A is the terminal 42 of the negative high voltage DC pulse.
A and a high-voltage DC pulse terminal 42B are alternately connected and this output is output to the output terminal 43. Preferred is a three-pole bidirectional thyristor, triac, SBS silicon bidirectional switch or It is desired to be formed by using an electronic device such as a switching diode.

The outputs from the switching converters 4A, 4B are added to the respective emission poles 6 via the changeover switches 5A, 5B.
It is desired that B has a multi-contact of at least two contacts.
That is, as shown in FIG. 3, the high reduction potential negative ions used for cleaning the contaminated air have a short reduction life of about several seconds, so that the building space A, etc. has a large partition volume. Emission electrode 6 for cleaning the air in the space
It is desirable to disperse a large number of electrodes, and the electric power applied to the emission electrode 6 to release the negative ions having a higher reduction potential than the emission electrode 6 is a negative high voltage of 10000 V and a DC pulse rate of 50 kilopulses / second. At most 3
Since the power consumption is about 6 mW to 6 mW, the changeover switch 5A has a large number of negative high-voltage DC pulse emission electrodes 6
It is advantageous to have a multi-contact type which can connect the induction cable 7 connected to the.

On the other hand, in the sewage treatment, after the pH is adjusted in the adjusting tank B for adjusting the pH value of the wastewater raw water as shown in FIG. 4, it is transferred to the biochemical processing tank C and subjected to the biochemical treatment. In the separation tank D, the decomposed organic matter frog is flocculated or floated or precipitated to achieve solid-liquid separation, and sterilization is performed in the sterilization tank E, and drainage F to a river or the like is performed. The sludge G is subjected to pressure dehydration or centrifugal dehydration and is discarded as industrial waste. Therefore, in the adjusting tank B in the sewage treatment process, a negative high voltage DC pulse or a positive high voltage DC pulse is added to adjust the pH value, and in the biochemical treatment tank C, a low voltage DC high pulse is added. Promote biochemical treatment by reducing the cluster of water molecules, and further improve cohesiveness by adding negative high voltage DC pulse in the separation tank D, or positive high voltage DC pulse in the sterilization tank E. Since it becomes possible to sterilize by adding the above, it is necessary to connect a large number of negative high-voltage DC pulse or positive high-voltage DC pulse induction cables 7 to the changeover switches 5A and 5B, and thus multi-contact switches are required. It will be.

In the present invention, since a negative high voltage DC pulse or a positive high voltage DC pulse is used, it is premised that each step is insulated when used for wastewater treatment, and the emission electrode 6 is made of air. It is arranged via an insulator so as to come into contact with air during cleaning and further come into contact with treated water in each treatment step during wastewater treatment. In addition, it goes without saying that the ion generator of the present invention is naturally formed in the casing 8 made of an insulating material having an appropriate shape and size.

An example of a high reduction potential negative ion release experiment will be described below. AC is used for the primary side of the ion generator of the present invention.

A pulse was output, and a positive high voltage DC pulse with a positive voltage of 4500 V and a substantial pulse number of 50 kilopulses / second was output from the secondary side of the other high frequency output transformer by half-wave rectification. Then, the positive high-voltage DC pulse is converted and mixed at a ratio of 1/50 with respect to the negative high-voltage DC pulse, mixed and converted by the switching converter, and then added to the emission electrode 6 and measured by the ion measuring instrument. As a result, an extremely high density of negative ion emission of approximately 2.8 million to 3.3 million / cc was confirmed.

As described above, according to the present invention, the frequency of 1 to 10 is provided on the primary side of the pair of high frequency output transformers.
High-frequency AC in the range of 0 kHz is input, and the output voltage on the secondary side is designed to be 3000 to 30,000 V. Also, one side of the secondary side of one high-frequency output transformer must be grounded via a rectifier. Then, the other side is a negative high voltage and is outputted as a negative high voltage DC pulse of 0.5 to 50 kilopulses / second by half-wave rectification,
Furthermore, one side of the secondary side of the other high-frequency output transformer is also grounded via the rectifier, so that the other side has a positive high voltage and half-wave rectification allows the number of pulses to be substantially 0.5.
Output as positive high-voltage DC pulses of 50 to 50 kilopulses / second, these outputs are input to a pair of switching converters, and one of the switching converters outputs 1/1 / minus negative high-voltage DC pulses.
The positive high-voltage DC pulse is intermittently converted and mixed at a rate of 20 to 1/100 and added to the emission electrode, and in the other switching converter, 1/20 to 1/100 of the positive high-voltage DC pulse. Since a negative high-voltage DC pulse is converted and mixed intermittently and added to the emission electrode, the water molecules near the emission electrode are subject to the electrochemical action due to the high voltage and the electrical shock action due to the high pulse. It instantly dissociates with low clustering to generate and release high reduction potential negative ions or high oxidation potential positive ions, and intermittently at a ratio of 1/20 to 1/100 in the output added to the emission electrode. Since the opposite potentials coexist, excessive charging near the emission pole does not occur and the addition is added in a wavy form by a pulse, so that high-density ion emission and Like ion effect over a wide range for emission discharge air is created is exerted, it can be said that a very innovative ion generation method and apparatus.
