FIG. 4A is a side view showing the internal structure of the organic substance decomposer 1 according to the embodiment of the present invention, and FIG. 4B is a plan view showing the internal structure of the organic substance decomposer 1 according to the embodiment of the present invention More specifically, each of the drawings shows the internal structure of the case 10 constituting the organic substance decomposing apparatus 1.
4A for the explanation of the internal structure of the housing 10, and FIG. 4B for the input cylinder 17 provided on the support leg 15 and the upper surface lid 16 as well as the conduit 31 and the upper surface lid 16 in addition to the conduit 31. Illustration is omitted.

At a connection portion between the upper surface lid 16 and the insertion cylinder 17, an insertion port 18 is provided so as to be openable and closable. The first space a can be sealed by storing the organic matter through the inlet 18 and closing the inlet 18.
In the state where the organic matter is stored in the first space a, as described above, the air taken in from the outside of the housing 10 through the intake pipe 20 having the magnet inside is ionized and flows into the second space b. Then, the ionized air flows into the first space a through the plurality of conduits 31 provided in the pair of partition plates 30.

Here, the conduit 31 protrudes from the pair of partition plates 30 with a certain length so that the ionized air increases in momentum toward the first space a to reach farther.
Each of the pair of partition plates 30 is provided at the same inclination angle, and the conduits 31 are provided in directions and positions facing each other on both sides of the pair of partition plates 30 to circulate ionized air described later. It becomes a suitable structure.

As a result, the ionized air returned from the first space a to the second space b through the slit 32 again flows from the second space b to the first space a through the conduit 31 and thereafter this path The circulation promotes the decomposition of the organic substance contained in the first space a.
A part of the intake pipe 20 may be provided with a vent (not shown) for restricting the inflow of air from the outside. Thereby, in conjunction with the opening and closing operation of the vent, the inflow of ionized air can be controlled to adjust the decomposition rate of the organic substance or to stop / start the decomposition reaction.

Further, a heat storage heater 34 is provided on the bottom wall 14 as an initial initial heating means for storing the organic matter in the first space a. A heat storage material is coated on the surface of the heat storage heater 34 to set a temperature range between about 0 and 100 ° C., and temperature management using a sensor can be performed.
Thereby, before the superheated steam described later is supplied to the first space a, the temperature inside the first space a can be raised in advance to promote the decomposition of the organic matter.
When the decomposition of the organic matter proceeds to some extent and the heat of decomposition is generated, thereafter, the decomposition cycle proceeds automatically, and the heating by the heat storage heater 34 is not necessary in principle. However, when the sensor senses that the internal temperature has dropped below the set temperature, the heat storage heater 34 may be operated again to perform heating.

Also, a superheated steam jet hole 63 is provided at a position slightly below the center of the inner wall 12, preferably on the side different from the side on which the partition plate 30 is provided, or the first space a Supply superheated steam to The first superheated steam device 60, which is a supply source of the superheated steam, will be described later.

Heaters 62 and 72 for generating superheated steam are provided inside the first superheated steam device 60 and the second superheated steam device 70, and two pipes connected to the first and second superheated steam devices 60 and 70. The saturated steam supplied from one side is converted to superheated steam by heating and supplied to the other pipe.
The surface temperature of the heaters for generating superheated steam 62 and 72 becomes about 700 to 800 ° C. at the time of heating. The temperature inside the first and second superheated steam apparatuses 60 and 70 is set to about 300 ° C., and temperature management using a sensor can be performed.

FIG. 6 is a side view showing the internal structure of the first superheated steam device 60 and the wood vinegar tank 50 which constitute the organic matter decomposer 1 according to the embodiment of the present invention.
As shown in FIGS. 3 and 4A, the water vapor generated in the first space a by the decomposition of the organic matter flows into the third space c through the through holes 13. The wood vinegar 51 which has been cooled and liquefied is stored in the wood vinegar tank 50. The wood vinegar 51 has relatively large impurities filtered by the filter 52, flows into the side of the wood vinegar tank 50 provided with the heater 53 for generating saturated water vapor, and is converted to saturated water vapor by heating. The surface temperature of the heater 53 for generating saturated water vapor is 200 ° C. or higher at the time of heating.

This saturated steam is further heated by the heater for superheated steam generation 62 provided in the first superheated steam device 60, and converted to superheated steam. The superheated steam flows into the first space a through the superheated steam injection holes 63 to further accelerate the decomposition of the organic matter.
Further, by repeating the cycle in which water vapor circulates between the first space a and the first superheated steam device 60, the impurities contained in the wood vinegar 51 are gradually decomposed, and the wood vinegar 51 is colorless and odorless and transparent. It changes to liquid. This eliminates the need for receiving inspection of waste water when disposing of wood vinegar.

Thus, the ionized air circulates between the first space a and the second space b, and the steam flowing from the first space a into the third space c is converted to superheated steam, and the first space a The organic substance stored in the first space a is gradually decomposed and is finally discharged as a ceramic residue by repeating flowing back to the.
As a result, not only the work of pre-sorting the organic substance to be treated becomes unnecessary, but also the organic substance after decomposition becomes 1/500 to 1/1000 in volume ratio before decomposition, and a significant volume reduction is realized. Furthermore, this ceramic residue can be utilized for soil improvement and plant growth promotion.

FIG. 7 is a side view showing the internal structure of the second superheated steam device 70 and the tank 40 which constitute the organic substance decomposer 1 according to another embodiment of the present invention.
As shown in FIG. 3, the water vapor generated in the first space a by the decomposition of the organic matter flows into the third space c through the through holes 13. Here, the remaining water vapor is discharged to the outside of the housing 10 from the discharge port 71 formed in the outer wall 11 except for the wood vinegar 51 which has been cooled and liquefied.

This steam is further heated by the heater 72 for producing superheated steam provided in the second superheated steam device 70, is converted into superheated steam, and is discharged by the liquid 43 through the discharge hole 42 bored in the communication pipe 41 inside the tank 40. It is filtered. Thus, the steam generated by the decomposition of the organic matter can be deodorized, and can be discharged to the outside through the cooling by the liquid 43.
Here, it is preferable that the superheated steam discharge holes 42 be located at the same level as the surface of the liquid 43 and be provided with the surface of the liquid 43 facing downward.
Although water is assumed to be used as the liquid 43, a further deodorizing effect can be expected by adding silver ions to the water.

The tank 40 is preferably further provided with a fan 45 for sucking the filtered superheated steam and discharging it to the outside. Here, the fan 45 is provided, for example, inside a discharge cylinder 44 provided to pierce the upper surface of the tank 40.
When the fan 45 exhausts the air inside the tank 40 to the outside, the inside of the tank 40 becomes negative pressure, and filtering with the liquid 43 of superheated steam can be efficiently advanced.
