Definitions
- processed material containing organic matter is passed through a strong magnetic field at a low temperature (250 ° C. to 400 ° C.), low oxygen (hereinafter “magnetization”). It is decomposed using 2500 gauss to 5000 gauss (magnetic field) called “air”, and other than metals, glass, stones and concrete (hereinafter referred to as metals) are ashed and the residue other than the metals is extremely reduced.
- the present invention relates to a method and an apparatus for low-temperature decomposition treatment of a processed material that can be performed (for example, 1/90000).
- Patent Document 1 a technique has been shown in which waste is dried, carbonized, and then ashed by heat of low-temperature heating of ash (for example, 350 ° C.) and magnetized air (for example, magnetic force of 4500 gauss) (Patent Document 1).
- a long processing time for example, a processing time of 10 hours or more
- magnetized air for example, magnetic force of 4500 gauss
- Patent Document 2 Although it is possible to cope with even a case where there is a lot of moisture, there is room for improvement in the overall efficiency and stable processing such that continuous decomposition such as defective decomposition or non-uniform decomposition becomes difficult.
- an organic substance is accommodated in a reaction vessel formed of a ferromagnetic material, and a pair of magnets arranged so that the N pole and the S pole are opposed to each other with an external conduit communicating with the inside of the reaction vessel interposed therebetween.
- Patent Document 3 a technique for causing a magnetic field vibration in an organic substance and decomposing it. According to the above-mentioned patent document 3, the decomposition process of the organic matter is explained once. 100 kg of raw garbage, 100 kg of waste paper, 100 kg of gypsum board and 150 kg of wood waste are charged and processed at a peripheral wall temperature of 50 ° C. to 60 ° C. for 24 hours. It is stated that it became ash.
- Patent Document 4 A shortening method has been proposed (Patent Document 4). Although the above seems to be characterized in that liquid metal lithium is used as a catalyst, it is unclear whether a large amount of radioactive waste can be treated continuously.
- the waste contained in the lower part of the treatment chamber is agitated during the treatment of the treatment product (waste), whereby the thermal decomposition treatment in the part is rationalized and equalized, and the treatment time is reduced to 20 times.
- % To 40% for example, 10 hours to 8 hours to 6 hours
- stable treatment was observed.
- Agitation is 1 to 2 times in 2 to 4 hours, and 5 to 10 minutes is sufficient for one stirring time (rotating shaft 5 to 10 times per minute).
- the processed materials to be put together are approximately 150 kg to 700 kg at 1 m 3 , if this is accommodated in the upper part of the processing tank, the weight of 150 kg to 700 kg is applied to the lower part of the untreated material in the processing tank. There will be no risk of occurrence.
- the lower end of the waste and the red hot part of the ash (for example, ceramic ash) are always in close proximity and facing each other, and the combustible material is rapidly dried by the radiant heat of the ceramic ash and magnetized air. And carbonized, and then promote ashing.
- the treatment of waste has required more than 10 hours and has been unstable.
- the treatment time is several hours (4 to 7 hours 1 m 3 ) and the efficiency is improved by continuous operation. It was found that improvement was observed and stable treatment was possible.
- the odor of the exhaust gas may increase.
- the present invention has successfully led the exhaust gas to the treatment tank and successfully removed the deodorant / deodorant and foreign matter by flooding and magnetization.
- the present invention can use a suitable amount of heated ceramic ash (350 ° C.) and magnetized air (for example, air that has passed a 4500 gauss magnetic field) to reduce radioactivity.
- the present invention sometimes breaks down the bridge, thereby reducing waste and ceramic ash.
- ionized oxygen ionization by passing through a strong magnetic field
- other activated air by making magnetized air with controlled air volume evenly flowed while making the opposite relationship the best.
- the conventional problems have been solved.
- the amount of oxygen in the above is less than the amount of oxygen required for combustion, but the proportion varies depending on the characteristics of the waste. Therefore, the best value is determined experimentally.
- a processing object is introduced from the upper part of the processing apparatus, the lower part of the processing object is heated, and magnetized air that has passed a magnetic field of 2500 to 5000 gauss is guided into the processing object.
- magnetized air that has passed a magnetic field of 2500 to 5000 gauss is guided into the processing object.
- the amount is adjusted, and the magnetized air naturally flows out from the air supply pipe protruding into the apparatus from the lower side wall of the processing apparatus to the center part, and the magnetized air lowers the inner periphery of the processing apparatus,
- the central part is raised and convected up and down.
- the temperature of the ash is maintained by the heat of decomposition. Since the heat of decomposition is used for the drying treatment of the processed product, there is no possibility that it will rise to 400 ° C. or higher. Even if the ash is not initially heated, the ash is heated with the progress of decomposition. However, since it takes a long time for the first time, it is preferable to start by heating the ash.
- the exhaust from the exhaust pipe is smoked and deodorized in a deodorizing and deodorizing treatment tank to be deodorized and deodorized.
- This is an intermittent charging method in which a new treated material is introduced when a void is generated in the material, and the treated material is a waste containing industrial waste, household waste, or other organic matter.
- the vicinity of the lower part of the charged processed material is periodically stirred, and when a new processed material is charged, the inside of the upper part of the processing apparatus is depressurized.
- a double-wall processing is performed in which a heating chamber is provided at the bottom of a bottomed cylindrical processing apparatus, a processing object is accommodated in the upper portion of the heating chamber, and magnetized air is supplied.
- a plurality of chambers are connected to the lower part of the heating chamber and the processing chamber.
- Magnetized air supply pipes are installed in a plurality of horizontal directions in multiple upper and lower stages from the side wall toward the center, and the supply pipes are magnetized to magnetize the incoming air.

- the treated materials in the above are industrial waste, household waste, and other treated materials including organic matter, and all other unnecessary materials such as stone glass, concrete, and ceramics are included.
- the ceramic ash in the present invention is residual ash (inorganic), mud or stone powder left after processing waste, but also includes ash obtained by processing normal waste. It can be attached at the time of processing equipment sale.
- 5kg to 10kg of ceramic ash is stored in the processing chamber, heated to 350 ° C to 400 ° C with a gas burner or the like, and then thrown away, and then continuously decomposed. Can do.
- the ceramic ash is buried and its function is preserved for 100 to 120 hours. If waste was thrown in during this time, it was recognized that the treatment would start again as soon as possible.
- ceramic ash maintains a constant amount (initially supplied amount, for example, 10 kg to 30 kg) and does not increase even if the decomposition treatment is continued, so that it does not require human power other than the addition of waste when the treatment is continued.
- the maximum temperature is 400 ° C.
- the outer wall of the processing apparatus is 60 ° C. or less, and there is almost no possibility of causing burns even if it is touched with bare hands. Further, since the outer wall of the processing chamber is doubled, there is no possibility of igniting or damaging other objects.

- the stirring device is used for 5 to 10 minutes every hour. If the stirring device automates the rotation of the stirring shaft using an electric circuit with a timer, the periodic stirring can be fully automated. In an area where there is no power transmission / distribution facility, a power source necessary for the automation can be obtained by, for example, a combination of power generation using sunlight and a battery.
- the introduction of waste in the above-described manner involves human power
- the introduction of waste can be fully automated if an automatic input device is connected to the input port of the decomposition processing device.
- an automatic input device For example, in the case of a device that throws in 1 m 3 of waste every 4 hours, the amount of daily input is 6 m 3 , so that a lower portion of a hopper capable of storing waste 6 m 3 is connected to the upper portion of the processing device. If a fixed amount charging device is attached to the lower part of the hopper and the charging device is automated, the waste can be fully automatically charged. Therefore, if the worker supplies 6 m 3 of waste once a day to the hopper, the waste for one day is processed fully automatically thereafter.
- the temperature of heat of decomposition of the waste is 400 ° C. (usually 250 ° C. to 350 ° C.). Therefore, even if the processing capacity decreases or is interrupted due to any failure, other harm is caused. There is no fear. However, if the waste inlet of the processing apparatus is left open, there is a risk that the waste will burn at normal temperature due to the supply of oxygen, but because of the structure of the processing apparatus, there is no risk that the lid will automatically open. It is safe without fear. Even if there is a case where it is unintentional that the operator forgets to close the lid, the operator suddenly raises white smoke by the lid and starts combustion, so the worker should notice.
- the inflow of magnetized air is determined by the exhaust amount. Therefore, if the waste water evaporates due to the heating of the ceramic ash, the suction amount of the magnetized air temporarily decreases as the evaporation amount increases. Therefore, a further comparative test is required for the intake amount of magnetized air and the efficiency of waste treatment.
- automatic inflow due to natural exhaust is not possible.
- a manual valve is provided on the suction side, and the amount of magnetized air sucked can be controlled by the processed material.

- the magnetized air since at least the processing chamber side walls are double walls and vents are provided at the top and bottom to circulate the magnetized air, the magnetized air generates up and down convection. That is, an upward flow is generated by the temperature of the heated ash (250 ° C. to 400 ° C.) in the heating chamber at the bottom. Accordingly, the magnetized air becomes an upward flow inside, becomes a downward flow at the peripheral wall portion (double wall), partially becomes exhaust, and new magnetized air is sucked in by the exhaust amount.
- the heat of decomposition is used for decomposition, and the remainder gathers in the ash, warming the magnetized air, and radiating infrared rays to the lower side of the processed material to accelerate its drying and decomposition. . Due to the presence of the heated ash, it was possible to confirm the decomposition efficiency and the stability and certainty of the decomposition.

Therefore, the processing time can be greatly shortened, and a rapid homogeneous process can be performed regardless of the material of the waste.
- the waste material is heated and dried with carbon ash heated to 250 ° C. to 400 ° C. and air magnetized with 2500 Gauss to 5000 gas, carbonized, and then ashed. Without being dependent on, there is an effect that the waste can be decomposed automatically and continuously and detoxified.

- residual ash can be treated to prevent an increase in residual ash, so there is no amount of residual ash removed during continuous waste disposal, or a small amount of residual ash is prevented from filling the combustion chamber. There is a possible effect. Furthermore, rationalization of the decomposition process can be achieved by adjusting the amount of magnetized air.
- PCB can be decomposed and rendered harmless.
- radioactive material can be treated to reduce its radioactivity. Therefore, if PCBs and contaminants caused by radiation are processed according to the present invention, there is an effect that they can be processed at a low level that does not affect the human body.

(Or even if there is no initial heating, the ash is automatically heated by the decomposition heat of the industrial waste), and the processed material (industrial waste, for example, food residue) is transferred to the processing chamber (for example, volume 2 m 3 ) of the processing device. 2m 3 (mixture such as plastic container, hereinafter referred to as “waste”) is charged and the inlet is sealed with a lid.
- An exhaust pipe is connected to the upper portion of the processing apparatus, and the exhaust pipe is connected to an exhaust treatment tank.
- the waste is dried by the radiant heat and magnetized air of the ceramic ash, then carbonized and further ashed, but a large amount of water vapor is generated and flows out of the exhaust pipe during drying. Therefore, when the inside of the processing apparatus is in a depressurized state, air to be magnetized flows from one end of the magnetized cylinder installed at the lower part of the processing apparatus. Therefore, the waste is moved to the bottom by the red heat radiation of the ceramic ash and the magnetized air. Then, the dry decomposition process proceeds, followed by carbonization and ashing.
- the lower part of the waste may form a bridge and the distance from the ceramic ash may increase.
- the stirring shaft is rotated and the bridge is broken by stirring.
- the waste falls onto the ceramic ash, and is heated and magnetized under magnetized air, and then ashed.
- the lid is opened and the necessary amount of waste is replenished. For example, if the initially filled waste 2m 3 becomes 1m 3 , the waste 1m 3 is newly added. If the shortage is added in this way, the waste of 1 m 3 or more always remains in the processing apparatus and the pressure is lowered by its own weight, and the waste is continuously processed in the same state. Depending on the material waste, waste and 2m 3 accommodated, because it is 1 m 3 at 4 hours to 5 hours, add-on is carried out every 4-5 hours.

- the waste can be continuously processed using the processing apparatus continuously. In this manner, in the experimental treatment apparatus of the example, about 6 m 3 of waste can be treated for one day (24 hours).
- the exhaust generated by the low-temperature treatment has a bad odor depending on the type of waste (for example, synthetic resin waste or old tires), so it is put into a deodorizing / deodorizing tank (processing tank) and deodorized with water, and then magnetized. And release it to the outside world.

- the lid 116 is sealed, the handles 118 and 118 are rotated as indicated by arrows 123 and 123, and the support plates 113 and 113 are indicated by arrows 124, If it opens like 124, the input material 125 will fall like the arrow 126 with dead weight. In this case, since the lid 116 is sealed, there is no possibility that the exhaust in the processing apparatus is discharged to the outside. As described above, it is possible to prevent exhaust leakage at the time of replenishing the input by using the support plates 113 and 113 and the lid 116.

(1)定量評価
(a) 一般廃棄物の減少(重量・容積)
(b) セラミック灰の消滅
(a) 一般廃棄物のセラミック化及び消滅
(b) 放射能の減少・消滅
平成19年10月24日~12月9日
栃木県那須烏山市 他
(1)牛糞等の処理能力
14日間の試験期間中、毎日約3~4トン(4~5m3)の牛糞および敷き藁等を処理機に投入し、灰等は一切取り出さない。
14日間の試験期間中、毎日2~3トンの産業廃棄物を処理装置に投入し、金属、コンクリート片以外は、一切取り出さない。
7日間の試験期間中、一般廃棄物の所定量以外は投入せず、安全性が保証された放射能パウダーを投入して、その放射能レベルの変化を測定する。
(1)牧場から排出される牛糞及び敷き藁等、一定の品質を保った廃棄物
約50トンの牛糞を投入したにも関わらず、処理機内の炭化物(黒色)、灰化物(灰色)及びセラミック灰(白色)の目視による量に変化が見られず、全体の処理速度も変化がない。
期間中、推定35トンの産業廃棄物を投入したにも関わらず、処理機内の残留物(灰状)の目視による量の増加は認められなかった。
放射能パウダーを糊で、綿のタオル、木片、ダンボール紙にそれぞれ10グラムずつ塗りつけ、処理機の中に投入し、広口耐熱ガラス瓶の中に、このパウダー10グラムを入れて処理機の中に投入した。
