[0008]

In the present invention, a halogen-based solvent, a chlorine-based solvent, or a methylene chloride solution is mixed with water, and the mixture is heated to a constant temperature to remove halogen ions or chlorine ions (Cl ⁻ ). The generated halogen ions or chlorine ions (Cl ⁻ ) act on the substance to be oxidized W on the treatment substance mounting table 26, so that the halogen ions or chlorine ions (Cl ⁻ ) have a strong oxidizing power. That is, the substance to be oxidized W having a strong binding force is oxidized at a low temperature that cannot be normally oxidized.

Particularly in steel materials, iron materials and other metals, when iron oxide or iron oxide is produced, it is usually heated to 600 to 1000 ° C. or higher in order to accelerate the oxidizing action. However, in the present invention, it is possible to oxidize a steel material, iron or metal at a low temperature of 100 ° C. or lower at which halogen ions can generate chlorine ions (Cl ⁻ ). In addition, even if the wood or the plant organic matter is cut down and withdrawn, the resin or the oil and fat is firmly contained in the inside of the cellulosic cells, and the resin is not output to the outside. If this resin remains in liquid form and oozes out in later years, it will adversely affect the wooden house. Since the resin of the timber is a long-chain fats, which chlorine ion (Cl ^-) cut by oxidizing power of, by coupling an alcohol group, as the alcohol state, or degreased from the cells, or cells The fats and oils remaining in 2) function as a bridge structure or a cross-linking structure in the long chain portion to cause the solid solution in the state of being unable to melt inside to crystallize.

[0010] Animal leather is a state in which animal fats and oils are encapsulated in the leather cells thereof, and it melts out during use as a leather product, or hardens with drying, making it impossible to use leather. And It is the tanning effect that takes out this animal fat and oil and makes it a crosslinked structure,
This is also the oxidative effect of melting and cross-linking structure of animal fats and oils, which are long chain molecules. In the past, tanning work was performed with lime, chromium oxide or the like, but the strong oxidization action of halogen ions and chlorine ions (Cl ⁻ ) according to the present invention enables easy tanning action.

PCB (polychlorinated biphenyl) is
It is harmful to the human body, its use is prohibited, and it is necessary to disassemble the existing PCB to make it harmless. However, the disassembly work of this PCB has hitherto been performed by irradiating ultraviolet rays to the PCB.
High cost treatments such as detoxification by decomposing bacteria and thermal decomposition at 1200 ° C or higher for incineration have been performed. In the present invention, since this PCB is also a chain-like biphenyl chloride resin, it can be easily decomposed by cutting with a halogen ion or chlorine ion (Cl ⁻ ) oxidizing force to alcohol or forming a cross-linked structure. The present invention provides a material oxidizing device using halogen ions.

Further, the vacuum pump P discharges the halogen-based solvent and water, the chlorine-based solvent and water, or the methylene chloride and water vapor remaining in the processing tank T and the processing substance after the mixed solution is pushed out. It is something to suck. Since the sucked vapor cannot be discharged into the atmosphere, it is cooled and liquefied in the condenser 16 and returned to the mixed liquid tank 14 from the portion of the condenser pipe 21. The chiller 15 cools the cooling water inside the condenser 16. Further, a filter 19 is provided to filter impurities such as dust in the mixed solution extruded from the processing tank T by the compressor C.

The boiler B, the vacuum pump P, and the chiller 15 are automatically stopped. One stroke of this process is configured to be completed in 5 to 24 hours. Next, FIG. 2 shows the state of the electromagnetic valve in each step of the substance oxidizing device using halogen ions.

First, in the "degassing" step, the vacuum pump P is driven. And vacuum pump P and condenser 1
The electromagnetic valve 1 of the circuit connecting 6 is opened, and the electromagnetic valve 3 which connects the condenser 16 and the processing tank T is also opened.
All other solenoid valves are closed. As a result, the inside of the processing tank T becomes a vacuum of about 50 Torr, and the air around the processing substance is drawn out.

Next, in the process of "feeding the mixed solution", the electromagnetic valve 4 which connects the processing tank T and the mixed solution tank 14 is opened, and the other electromagnetic valves are closed. As a result, the mixed solution tank 14 and the processing tank T are arranged at substantially the same level, so that the mixed solution is treated so that the mixed solution tank 14 and the processing tank T are at the same level.
Move in.

Next, in the process of "treatment", the electromagnetic valve 7 between the boiler B and the processing tank T and the electromagnetic valve 9 connecting the drain from the processing tank T to the drain are opened, and the other electromagnetic valves are closed. It As a result, the high-heat steam from the boiler B is supplied to the heating / cooling pipe 20 in the processing tank T, and the mixed liquid in the processing tank T becomes methylene chloride vapor and water vapor and permeates into the inside of the processing substance. . This "treatment" step is performed for about 6 to 36 hours.

Next, the process of "mixed liquid cooling" will be described. In this case, the electromagnetic valve 8 that connects the cooling water tank 18 and the processing tank T, the processing tank T, and the cooling water tank 17 are connected.
The electromagnetic valve 10 that communicates with is opened. The other solenoid valve is closed. As a result, the cooling water passes through the heating / cooling pipe 20 and the inside of the processing tank T becomes 40 ° C. or lower, which is the boiling point of methylene chloride, so that both methylene chloride and steam return to the chemical liquid.

Next, the process of "returning the mixed liquid tank" will be described. In this case, the electromagnetic valve 2 is opened to release the air in the processing tank T, the electromagnetic valve 5 under the processing tank T and the electromagnetic valve 6 that connects the compressor C and the processing tank T are opened, and the compressor C is opened. Driven. In addition, the electromagnetic valve 12 between the filter 19 and the mixed liquid tank 14
And an electromagnetic valve 13 for communicating the mixed liquid tank 14 with the atmosphere
Opens. As a result, a certain amount of pressure is applied to the processing tank T, so that the liquefied mixed liquid is pushed back into the mixed liquid tank 14.

Next, the process of "collection of vapor mixture in tank" will be described. In this case, the vacuum pump P is driven. Then, the electromagnetic valve 1 that connects the vacuum pump P and the capacitor 16 and the electromagnetic valve 3 that connects the capacitor 16 and the processing tank T are opened. The other solenoid valve is closed. In this state, the vacuum pump P collects the vapor of methylene chloride that has penetrated into the processing tank T and the processing substance. The degree of vacuum at this time is lowered to about 200 Torr.

Next, referring to FIG. 8, a sectional view of the inside of the processing tank T in the processing state will be described. Below the inside of the processing tank T, a heating / cooling pipe 20 is arranged,
On the upper part of the heating / cooling pipe 20, a processing substance mounting table 26 is placed.
Are movably arranged. The treatment substance is placed on the treatment substance placing table 26. The liquid mixture of water Wa and the methylene chloride solution Me has a higher liquid level than the heating / cooling pipe 20, but the liquid level is such that the treatment substance on the treatment substance mounting table 26 is not immersed. Injected.

The specific gravity of water Wa is 1.00, whereas the specific gravity of the methylene chloride solution Me is 1.33.
Since it does not dissolve in water Wa, it forms a layer below the layer of water Wa. Then, when the steam heated to 160 ° C. is supplied to the heating / cooling pipe 20 arranged in the layer of the water Wa, the temperature around the heating / cooling pipe 20 rises. The heating / cooling pipe 20 is arranged in a layer of water Wa, and the temperature of the portion rises first.

When the temperature of the heating / cooling pipe 20 gradually rises and reaches about 40 ° C., the methylene chloride solution Me
Reaches the boiling point and changes to methylene chloride vapor, water Wa
Passing through the layer as a bubble, becoming chlorine ions (Cl ⁻ ) and moving in the processing tank T. Then, the substance reaches the treatment substance, the air is deaerated, and the oxygen penetrates into the treatment substance in a state where the oxygen is small, thereby promoting the oxidizing action. When the substance to be treated is wood, it is heated to about 40 ° C. to 150 ° C., and the vapor of methylene chloride penetrates through the liquid of water Wa to continue the treatment in such a state that it reaches the substance to be treated. While the methylene chloride Me passes through the water Wa,
Chlorine ion (Cl ⁻ ) is generated, Cl ₂ (chlorine gas) generated from methylene chloride is absorbed in water Wa,
This suppresses the generation of Cl ₂ which adversely affects the processing.

Further chlorine ions generated from the methylene chloride vapors (Cl ^-) is in entering the process material. Thus methylene chloride vapor and water vapor, free to move can chlorine ions (Cl ^-) is generated,
This chlorine ion (Cl ⁻ ) easily penetrates into the inside of the treatment substance and combines with the atom of hydrogen or oxygen in the middle part of the chain molecule of the treatment substance to change it into an alcohol compound. Then, the treated material is shredded.

Oxidation of the treatment substance is generated by the oxidation action of the treatment substance and the fragmentation action due to the methyl alcohol formation. In this way, by heating the water Wa and the methylene chloride solution Me as a mixed liquid by the heating / cooling pipe 20, the vapor of the methylene chloride Me passes through the water Wa and then enters the treatment tank T. As it evaporates, Cl ₂ decreases, and chlorine ions (Cl ⁻ ) are generated. The chlorine ion (Cl ⁻ ) penetrates into the processing substance.

[0032]

Since the present invention is the above-mentioned substance oxidizing apparatus using halogen ions, it has the following effects. Since the air inside the processing tank T is degassed by the vacuum pump P and the amount of oxygen is small, the halogen-based solvent, the chlorine-based solvent, the vapor generated from the methylene chloride solution and the water are halogen ions and chlorine. It generates ions (Cl ⁻ ). The halogen ions and the chlorine ions (Cl ⁻ ) act on the treatment substance in the treatment tank T in the air, so that the treatment substance, which has been difficult to oxidize in the past, can be oxidized. .

Further, the substance oxidizer using the halogen ion is applicable to metals, wood, plants, alloys, ceramics, PC.
It can act on all chemical substances such as B to exert a strong oxidizing action. Also, in the substance oxidation device using this halogen ion, when methylene chloride is used, there is almost no decrease in the amount of this solvent used, and it is possible to recover to a nearly complete state, so air pollution and ozone layer destruction There is no adverse effect on the earth.

Further, as in the prior art, instead of making the active state of the electrons and atoms of the treatment substance by high heat and causing the oxidation action, the oxidation treatment can be performed at a low temperature of 100 ° C. or less. It is possible to provide a safe device with less damage.
