Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

< Structure of organic substance decomposition/treatment apparatus of the present invention >

Fig. 1 is a schematic diagram showing the overall configuration of an organic matter decomposition treatment apparatus 1 according to the present invention. The organic matter decomposition treatment apparatus 1 is configured to decompose various organic matters such as raw garbage such as vegetable residues and polymer materials and paper materials by using oxonium ions. Examples of the oxonium ion include hydronium ion, oxatriquinolizine, and triquinolizine oxalate, and the oxonium ion is a positive ion. In this case, the organic matter decomposition treatment apparatus 1 includes a tank 2 for charging organic matter, a blower 3, and an ion generator 4 for organic matter decomposition treatment.

Organic substances to be decomposed are introduced from the inlet 2a of the storage tank 2 and stored in the storage tank 2. The organic matter after the decomposition treatment can be discharged to the outside through the discharge port 2b of the storage tank 2. In this case, the organic substance decomposition treatment apparatus 1 includes a heater and a stirrer, not shown, therein, and heats and stirs the organic substance by irradiating the organic substance in the storage tank 2 with oxonium ions generated in the organic substance decomposition treatment ion generation apparatus 4, thereby evaporating moisture of the organic substance and performing decomposition treatment.

The blower 3 and the organic substance decomposition ion generator 4 are disposed at predetermined positions of the storage tank 2, and the blower 3 and the organic substance decomposition ion generator 4 are connected by a pipe 5. The blower 3 sucks in outside air and sends out the sucked air to the organic substance decomposition treatment ion generator 4 through the pipe 5. The gas sent from the blower 3 into the organic substance decomposition ion generator 4 is sent into the storage tank 2 through the interior of the organic substance decomposition ion generator 4.

The ion generating device 4 for organic matter decomposition treatment includes: a case 8 in which an electrode structure described later is provided; and a dc power supply section 9. The casing 8 is provided with an inlet (not shown) connected to the pipe 5 for introducing the gas discharged from the blower 3 into the casing 8. The casing 8 is provided with a discharge port (not shown) that communicates with the storage tank 2 and discharges the gas from the blower 3 into the storage tank 2.

The casing 8 has a sealed space formed therein, and by introducing the gas from the blower 3 into the sealed space, a gas flow is formed in which the gas flows from the inlet port to the outlet port via an electrode structure (described later). Thereby, the housing 8 sends out the oxonium ions generated inside from the discharge port into the storage tank 2.

The dc power supply unit 9 generates a positive dc voltage and applies the positive dc voltage to the electrode structure in the case 8. The dc power supply unit 9 includes a voltage control unit 10 capable of controlling a voltage value of the dc voltage, and the dc voltage is set to a predetermined voltage value by the voltage control unit 10. Thus, the voltage control unit 10 can generate positive corona discharge by the electrode structure to generate oxonium ions in the electrode structure. At this time, the voltage control unit 10 sets the voltage value of the dc voltage to an optimum value in order to generate oxonium ions having a high decomposition processing capability of organic substances.

< about electrode Structure >

Next, the electrode structure provided in the housing 8 of the organic substance decomposition ion generating device 4 will be described below. As shown in fig. 2A, the electrode structure 11 includes a needle electrode 12, a plate electrode 13, and an electrode support member 14. The electrode support member 14 is made of an insulating material such as polyvinyl chloride, and is formed in a cylindrical shape to support the needle electrode 12 and the plate electrode 13.

In the present embodiment, the case where the cylindrical electrode support member 14 is used as the cylindrical electrode support member has been described, but the present invention is not limited to this, and a square cylindrical electrode support member such as a square or polygon may be used.

The electrode supporting member 14 supports the needle electrode 12 and the plate electrode 13 so as to be arranged opposite to each other in the hollow space ER1 surrounded by the cylindrical inner wall portion 14 a. The electrode support member 14 is disposed between an inlet and an outlet (not shown) of the casing 8 (fig. 1). Thus, when the gas from the blower 3 is introduced into the housing 8 from the inlet, a gas flow flowing in one direction (for example, an arrow direction of the central axis X) along the central axis X in the hollow space ER1 is formed in the hollow space ER 1.

More specifically, it is preferable that the electrode supporting member 14 be disposed in the casing 8 so that the inlet and the outlet of the casing 8 are disposed on the central axis X of the hollow space ER 1. In particular, by directing the opening end of the hollow space ER1 of the electrode supporting member 14 toward the discharge port of the case 8, an air flow linearly connecting the discharge port from the hollow space ER1 can be formed. This can prevent oxonium ions (described later) generated in hollow space ER1 from colliding with the inner wall of case 8, and can guide the oxonium ions directly to the discharge port.

As shown in FIG. 2B, the electrode supporting member 14 has an inner diameter Y between cylindrical inner wall portions 14a₂Selected to be 25 + -5 mm and an external diameter Y₃Selected to be 32 + -5 mm.

As shown in fig. 2B, the needle electrode 12 and the plate electrode 13 are disposed to face each other on 1 orthogonal line Y orthogonal to the central axis X of the hollow space ER1, and the plate portion 13B of the plate electrode 13 is disposed directly below the needle-like distal end portion 12a of the needle electrode 12. The needle electrode 12 is formed of a metal material such as tungsten, and has a diameter selected to be 0.1 to 2 mm. The needle electrode 12 is provided so as to penetrate the cylindrical inner wall portion 14a of the electrode supporting member 14, and the needle-like distal end portion 12a is exposed in the hollow space ER 1.

The plate electrode 13 is formed of a metal material such as stainless steel, and includes a rod-shaped support portion 13a and a plate portion 13b formed at an end of the support portion 13 a. The flat plate portion 13b is formed in a disk shape having a diameter of 5 to 20mm and a thickness of 1.5 + -1 mm. The support portion 13a is provided so as to penetrate the cylindrical inner wall portion 14a of the electrode support member 14, and the flat plate portion 13b is exposed in the hollow space ER 1.

In the present embodiment, the case where the support portions 13a of the needle electrode 12 and the plate electrode 13 are provided so as to penetrate the cylindrical inner wall portion 14a has been described, but the present invention is not limited to this. For example, the root tip of the needle electrode 12 may be fixed to the surface of the cylindrical inner wall portion 14a, and the needle electrode 12 may be provided so as not to penetrate the cylindrical inner wall portion 14 a. In the plate electrode 13, the support portion 13a or the plate portion 13b may be fixed to the surface of the cylindrical inner wall portion 14a so as not to penetrate the cylindrical inner wall portion 14 a.

The interelectrode distance Y between the needle-like tip 12a of the needle electrode 12 and the flat plate portion 13b of the flat plate electrode 13 facing the needle-like tip 12a₁For example 20 mm. Further, the inter-electrode distance Y₁The voltage is not limited to 20mm, but is basically defined by the voltage value (kV) and the electric field strength (kV/mm) of a positive DC voltage to be described later.

Here, as shown in fig. 2A, the voltage control unit 10 is connected to the root of the needle electrode 12 exposed outside the electrode support member 14. In this embodiment, the plate electrode 13 is grounded. The plate electrode 13 may be connected to the voltage control unit 10 without being grounded, and may be applied with a negative dc voltage to function as a negative electrode.

In the case of the structure in which the plate electrode 13 is grounded, it is preferable that the electric field strength of the positive dc voltage applied to the needle electrode 12 by the voltage control unit 10 is 0.25 to 1.5kV/mm, and the voltage value is 5 to 30 kV. The distance Y between the electrodes can be set by setting the electric field intensity of the positive DC voltage to 0.25-1.5 kV/mm₁A positive polarity corona discharge is stably generated.

Even when the electric field intensity of the DC voltage is 0.25 to 1.5kV/mm, if the voltage value of the DC voltage with positive polarity is less than 5kV, it is difficult to generate sufficient oxonium ions for decomposition treatment of organic substances. Further, when the voltage value of the positive dc voltage exceeds 30kV, the conditions for maintaining the stability of discharge become very strict as compared with the case where the voltage value is 30kV or less, and there is a possibility that the practicability is lowered from the viewpoint of maintenance and the like. Therefore, it is preferable that the electric field strength of the direct current voltage is set to 0.25 to 1.5kV/mm and the voltage value of the direct current voltage having the positive polarity is set to 5 to 30 kV.

As described above, by applying the direct-current voltage of the above-described voltage value to the needle electrode 12, a steady-state nonuniform electric field is generated between the needle electrode 12 and the plate electrode 13 which are in atmospheric pressure, and a positive-polarity corona discharge is generated. This enables generation of oxonium ions in the hollow space ER1 serving as a discharge space.

The difference between the discharge in vacuum and the discharge in the atmosphere will be described. The same needle electrode 12 and plate electrode 13 were used, and kV/mm was fixed, and the voltage and the inter-electrode distance were changed. In the case of vacuum, the electric field intensity distribution becomes similar. However, in the case of the atmosphere, the electric field intensity distribution is not necessarily similar because of the influence of the positive and negative ions present in a slight amount. As the distance between the electrodes increases, the influence of positive and negative ions increases, and it is difficult to ensure the stability of discharge.

Here, one of the main reactions for generating ions in the discharge space is a generation reaction of molecular ions. For ionizing gas molecules M into molecular ions M⁺And an electron e^-It is necessary to supply the gas molecules M with energy higher than the ionization energy (ionization energy) of the gas molecules M. In the discharge space under atmospheric pressure, this energy is imparted by collision of electrons accelerated in a high-electric-field glow region.

Primary ions generated by the discharge travel in the electric field along the electric line of force in their own polarity. When the primary ions directed toward the plate electrode 13 have a mean free path, they collide with the gas present in the discharge space and the discharge by-products from the neutral radical species a, [ M-B ] and B, causing various ion molecular reactions, and become ion species having a longer lifetime. The process moves and continues in the drift region, and final ions are generated through successive ion molecular reactions.

In the case of positive corona discharge in the atmosphere, the oxonium ion becomes a final ion regardless of the discharge condition. The generation and development of oxonium ions in the positive corona discharge in the atmosphere are predicted based on the measured values of the rate constants of the respective basic reactions. Thus, for example, the hydronium ion in the oxonium ion generates N by ionization in the glow region₂ ⁺And O₂ ⁺As primary ion, via involving mainly H₂O is generated by the process of development.

< Oxidation capacity with respect to oxonium ion >

Next, the oxidizing ability of the oxonium ion will be described. The amount of atomic stabilization is the amount of energy released. The electron affinity is energy released when one electron is taken in to the outermost layer. The high electron affinity indicates that the electron is taken from the object and the object itself tends to be stable. That is, it can be said that the oxidation ability is strong when the electron affinity is large.

FIG. 3 is a graph showing the relationship between atomic number and electron affinity. The electron affinity of fluorine (F) and chlorine (Cl), which are halogen elements, is extremely high when compared in the same cycle. The electron affinity of chlorine is very high, 3.617 eV. Usually becomes an anion having a valence of 1 upon ionization. Here, the electron affinity of the 1-valent cation of a certain atom is considered. The 1 st ionization energy of an atom represents the energy required to abstract an electron from the outermost layer of the atom to form a monovalent cation. That is, it can be said that "the electron affinity of a 1-valent cation of a certain atom" is equal to "the 1 st ionization energy of the atom".

The 1 st ionization energy of the rare gas is extremely large in the same period, but it is difficult to ionize the rare gas in, for example, discharge or the like. Except for the rare gas, the elements having ionization energy of 1 st higher than that of hydrogen are only nitrogen, oxygen, fluorine, and chlorine. Fluorine and chlorine are substantially absent as monomers. Nitrogen and oxygen do not become cations having a valence of 1, for example, in discharge. Therefore, the hydrogen ion is largest as the electron affinity of the 1-valent cation.

For example, in the oxonium ion, the hydronium ion is H⁺And H₂O, and thus the electron affinity (oxidizing power) of the hydronium ion is equal to that of the hydrogen ion, about 13.6 eV. From this value, it can be said that the oxidation power of hydronium ions is much higher than the oxidation-reduction potential of active oxygen species.

Next, a verification test for confirming the strength of the oxidizing ability of the oxonium ion was performed. In this verification test, the electrode structure 11 shown in fig. 2A and 2B was produced, and an oxonium ion was generated using this electrode structure 11. Here, a needle electrode 12 of 1mm in diameter made of tungsten, a disk-like plate electrode 13 of 10mm in diameter and 1.5mm in thickness made of stainless steel, and an internal diameter Y were used₂Is 25mm, and has an outer diameter Y₃Electrode structure 11 of the example was fabricated using electrode supporting member 14 made of polyvinyl chloride having a thickness of 32mm and 1.4 mm.

In this embodiment, the inter-electrode distance Y₁20mm, 20kV was applied to the needle electrode 12 as a positive DC voltage, and the plate electrode 13 was grounded. This makes it possible to confirm that electric discharge is present between the needle electrode 12 and the plate electrode 13. Since a direct current voltage of positive polarity is applied to the needle electrode 12 and the plate electrode 13 is grounded, the discharge is positive polarity corona discharge.

Then, a plurality of iron nails were prepared, and the opening end portion of the electrode supporting member 14 was brought close to the iron nails, and the positive polarity corona discharge was continuously generated for about 48 hours. In contrast, as a comparative example, an anion/ozone generator (an anion generator MHM305 manufactured by village and an anion/ozone generator MHM306 manufactured by village) was prepared, and the irradiation of anions and ozone was continued for about 48 hours to a plurality of nails in the same manner. The conditions for irradiation with negative ions and ozone were set such that the irradiation with negative ions and ozone was continued for about 48 hours for a plurality of nails. The applied voltage was set to 2kV in accordance with the specification of the product.

As a result, in the examples, it was visually confirmed that the entire surface of the iron nail was blackened and rusted. On the other hand, in the comparative example, it was visually confirmed that the surface of the iron nail almost maintained the initial silver color and was hardly rusted. Thus, it was confirmed that the examples have higher oxidizing ability than the comparative examples using active oxygen species.

< relationship between oxidizing power and drying power of oxonium ion >

Here, the boiling point of water was 100 ℃ and the heat of vaporization was 2250 kJ/kg. The boiling point of ethanol is 80.3 ℃, and the gasification heat is 393 kJ/kg. The boiling point of the ether was 34.5 ℃ and the heat of vaporization was 327 kJ/kg. Thus, it is understood that water has an extremely large heat of vaporization. This is thought to be because water molecules have polarity and hydrogen bonds act to form blocks called clusters.

The vaporization heat of water was 2250kJ/kg, which was about 0.4eV per 1 molecule of water. For example, when hydronium ions approach cluster water molecules, the oxidation ability (electron affinity) of 13.6eV acts to strip electrons forming hydrogen bonds, and it is expected that the electrons are converted into free electrons having high energy (about 13 eV). The high-energy free electrons collide with the electrons forming the hydrogen bond, and it is expected that the electrons are further converted into high-energy free electrons.

When the oxonium ion is irradiated, the oxidation reaction is linked, and the size of the cluster molecule is expected to be small. The structure and stability of the water clusters have been studied in recent years through experiments and calculations. In computational chemistry, for cyclic clusters (H)₂O)_nA structure in which n is 3 to 60 is studied. The calculation results were obtained that the distance between oxygen atoms was shortened as the ring became larger.

This is considered to be because the charge distribution of the molecules that accept hydrogen through hydrogen bonds changes, and the force of supplying hydrogen also increases, so if the aggregate of water becomes large, the hydrogen bonds are synergistically strengthened. This means that if the cluster size becomes small, the heat of vaporization becomes small. Several isomers are expected in the hexamer of water molecules, and it is calculated that cyclic, intrinsic, pocket, cage, and prism substances have approximately the same degree of stability. For the heptamer, 2 kinds of cage isomers were also obtained by calculation, and for the octamer, cyclic isomer and stereoisomer were calculated. Further, as a huge cluster, a fullerene-type 28-mer "bucky water", 280 water molecules were aggregated into a cluster in a regular icosahedron shape, and the minimum value of energy was calculated. In recent years, analysis of water clusters has also been performed by abinitio method (non-empirical method).

Here, if the evaporation rate of water is denoted by v, the vaporization heat is denoted by L_VWith respect to these evaporation velocities v and the heat of vaporization L_VThe relationship of (a) can be expressed by the Clapeyron-Clausius equation as follows.

v＝v_O·exp(-L_V/k_BT)…(1)

Here, v_ODenotes the integration constant, k_BThe Boltzmann constant is shown, and T is temperature.

FIG. 4 shows v/v_OValue of as heat of vaporization L_VIs expressed as a function of (c). As can be seen from FIG. 4, the heat of vaporization L_VWhen smaller, the evaporation rate v becomes larger. Therefore, the oxidation reaction is linked by the irradiation with the oxonium ion, and if the cluster molecule size is small and the vaporization heat is small, the vaporization rate becomes high. Therefore, when the organic material is irradiated with oxonium ions, it is expected that more water is evaporated with the same energy. The test for verifying the drying ability using oxonium ion will be described later in "example".

< action and Effect >

In the above configuration, in the organic decomposition treatment ion generating device 4, the needle electrode 12 and the plate electrode 13 are disposed to face each other, and a positive dc voltage is applied to the needle electrode 12 by the dc power supply unit 9. The dc power supply unit 9 sets the dc voltage to a predetermined voltage value by the voltage control unit 10, and generates a positive corona discharge between the needle electrode 12 and the plate electrode 13 in the atmospheric pressure.

In this way, in the ion generating apparatus 4 for organic substance decomposition treatment, oxonium ions having high capability of organic substance decomposition treatment can be generated by the positive corona discharge generated between the needle electrode 12 and the plate electrode 13. Therefore, in the ion generating apparatus 4 for organic matter decomposition treatment, the decomposition treatment capability of organic matter can be further improved by using oxonium ions for the decomposition treatment of organic matter than in the past.

In the ion generating apparatus 4 for organic decomposition treatment, the needle electrode 12 and the plate electrode 13 were disposed in opposition to each other in the hollow space ER1 of the electrode support member 14, and positive corona discharge was generated. Accordingly, the organic matter decomposition treatment ion generating device 4 can discharge the oxonium ions only from the opening end of the cylindrical electrode supporting member 14, and therefore, by selecting the direction of the opening end, the oxonium ions can be collectively sent only in a desired direction. Accordingly, the organic matter decomposition treatment ion generator 4 can suppress scattering of oxonium ions radially in the case 8, and can scatter the oxonium ions to a further position in a desired direction.

In the organic decomposition processing ion generating device 4, the electrode supporting member 14 is disposed so that the outlet of the casing 8 is positioned on the central axis X of the hollow space ER1, and the gas from the blower 3 introduced into the casing 8 from the inlet is linearly sent to the outlet through the hollow space ER 1. Thus, in the organic substance decomposition treatment ion generating apparatus 4, the oxonium ions generated in the hollow space ER1 can be directly introduced into the storage tank 2 from the discharge port. Accordingly, the portion where the oxonium ion is blown into the case 8 is limited, and damage to the inside of the case 8 by the oxonium ion having a strong oxidizing ability can be suppressed accordingly.

< other embodiments >

The present invention is not limited to the above-described embodiments, and can be modified as appropriate within the scope of the present invention. For example, the electrode structure body 11 may be provided at various positions within the case 8. In addition, as the organic matter decomposition processing apparatus 1, a case has been described in which the organic matter is decomposed by simultaneously heating and stirring the organic matter in addition to the irradiation of the oxonium ions to the organic matter, but the present invention is not limited thereto. For example, the organic substance decomposition processing apparatus may irradiate only the organic substance with oxonium ions, or may irradiate the organic substance with oxonium ions, or may heat or stir only the organic substance.
