Description

  The present invention relates to an organic matter processing method for decomposing organic matter such as garbage and an apparatus used therefor.

  Conventionally, a garbage processing machine as shown in Patent Document 1 is known. This garbage processing machine introduces hot air into the processing machine in which the garbage is stored, vaporizes the moisture contained in the garbage into steam, cools the steam, and discharges it outside in a condensed and liquefied state. This is a device for drying and reducing the volume of garbage. If the food waste to be processed is leftover food at home, it can be reduced in volume. For example, if it is the head of livestock discharged at a meat processing factory, The volume cannot be reduced without the bones being disassembled. Even if the volume can be reduced by drying, if the treated product is left as it is, the treated product absorbs moisture contained in the outside air, decays due to the action of microorganisms, and produces a foul odor. I will let go.

In the present embodiment, the safety valve 16 is operated and opened at a pressure of 1.8 MPa. The safety valve 16 includes both a mechanical type and an electromagnetic type.

  Support shaft holes 1 f are formed in the side plates at both ends of the sealed container 1 to communicate the inside and outside of the sealed container 1. In the present embodiment, the support shaft hole 1f is formed at the center of the side plate. A bearing member 20 is attached to the spindle hole 1f. The bearing member 20 has a bearing such as a ball bearing and a packing. The support shaft 2a of the stirring blade member 2 passes through the support shaft hole 1f of the hermetic container 1 and the bearing member 20, and the stirring blade member 2 is rotatably attached to the bearing member 20.

One end of the steam discharge pipe 2 d communicates with the steam flow path pipe 2 c, and the other end opens into the sealed container 1. With such a configuration, the water vapor supplied to the steam flow path pipe 2c is discharged into the sealed container 1 from the steam discharge pipe 2d. It should be noted that the support shaft 2a may be formed in a pipe shape so that water vapor flows through the support shaft 2a.

  The water vapor generating device 3 is composed of a boiler or the like, and purifies the heated water vapor. This heated steam is steam at 100 ° C. to 500 ° C./0.7 to 1 MPa, and includes dry steam and saturated steam.

  As shown in FIG. 1, a pipe 31 is connected to the water vapor generating device 3. Heated steam generated by the steam generator 3 is supplied to the pipe 31.

  A pipe 32 and a pipe 33 are connected to the pipe 31. In other words, the pipe 31 is bifurcated at its tip. The pipe 32 is connected to the pipe 34. The pipe 34 is connected to the steam channel pipe 2 c via the swivel joint 40. By using the swivel joint 40 in this way, the heated steam and the dried superheated steam are introduced into the steam channel pipe 2c provided on the spindle 2a of the rotating stirring blade portion 2 without leaking the heated steam and the dried superheated steam. As will be described later, even when heated steam is supplied in a state where the sealed container 1 is sealed, the pressure in the sealed container 1 can be increased.

  The pipe 32 is provided with a pressure control valve 51, a pressure detection unit 52, and a stop valve 53 in order from the steam generation device 3 side.

  The pressure control valve 51 is a valve that adjusts the pressure of the pipe 32 downstream of the pressure control valve 51, that is, the pressure of the steam flow path pipe 2c.

  The pressure detection unit 52 is a device that detects the pressure in the pipe 32.

  The stop valve 53 is a valve that blocks the flow path of the pipe 32. In the present embodiment, the stop valve 53 is a solenoid valve.

  A stop valve 62 is provided in the middle of the pipe 33. The stop valve 62 is a valve that blocks the flow path of the pipe 33. In the present embodiment, the stop valve 62 is a solenoid valve.

  The pipe 33 is connected to the separator 61. The separator 61 is a device that separates water droplets and suspended substances that are accompanied with heated steam. The separator 61 is connected to the steam trap 63 via the pipe 35. The water droplets and suspended matter separated by the separator 61 circulate in the pipe 35 and are guided to the steam trap 63.

  The steam trap 63 is a device that discharges only water droplets and suspended matters to the outside without leaking water vapor. In the present embodiment, the stop valve 64 is connected to the pipe 35 in case the steam trap 63 is damaged. When the steam trap 63 is damaged, the stop valve 64 is opened to discharge water droplets and suspended matters to the outside.

  The separator 61 and the superheater 4 are connected via a pipe 36. The piping is provided with a pressure reducing valve 66, a pressure detecting unit 67, and a stop valve 68 in order from the separator 61 side.

  The pressure reducing valve 66 is a device that reduces the pressure of the heated steam supplied to the superheater 4. In this embodiment, the heated steam is decompressed to 0.1 to 0.3 MPa. Thus, the reason why the heated steam is decompressed by the decompression valve is to prevent excessive moisture from being supplied to the superheater 4.

  The pressure detection unit 67 is a device that detects the pressure in the pipe 36.

  The stop valve 68 is a valve that blocks the flow path of the pipe 36 and blocks heated steam supplied to the superheater 4.

  The superheater 4 is a device that further heats the heated steam to give a large amount of latent heat to generate dry superheated steam. Here, the dry superheated steam is steam having a dryness of 100% (steam not containing a saturated liquid, that is, steam in a gas phase). Since the separator 61 is provided in the front stage of the superheater 4 for generating dry superheated steam to remove water droplets, excessive moisture is not supplied to the superheater 4. In this embodiment, dry superheated steam at 110 ° C. to 500 ° C. and 0.1 to 0.3 MPa is generated. The superheater 4 includes an electromagnetic induction heating type, a heating wire heating type, and a burner heating type using fossil fuel. In the present invention, the superheater 4 is preferably of an electromagnetic induction heating type.

  The electromagnetic induction heating type superheater 4 includes a tube, a heating element, an induction heating coil, and a high frequency power supply device. The heating element is a laminate in which a large number of metal thin plates are laminated, or a metal layer formed on the surface of a porous ceramic, and has a remarkably large surface area compared to the volume. This heating element is disposed inside the tube. The induction heating coil is disposed outside the tubular body. The high frequency power supply device supplies a high frequency current to the induction heating coil. When a high-frequency current is passed through the electromagnetic induction heating coil, an alternating magnetic flux is generated from the induction heating coil, an eddy current flows through the heating element, and the heating element generates heat due to the electric resistance heat of the eddy current flowing through the heating element. The heating element can be heated to 120 ° C. As described above, since the surface area of the heating element is large, the area in contact with the heated steam flowing through the tube body is large and is heated instantaneously to generate dry superheated steam. In addition, since the heating element has a small volume with respect to the surface area, the heat capacity is small.For this reason, the heating element can be instantaneously heated and lowered, and as described above, the heating element has a large surface area. The temperature of the dried superheated steam generated by the superheater 4 can be instantaneously raised and lowered, and temperature control is easy.

  The superheater 4 is connected to the pipe 34 via the pipe 37. A stop valve 69 is provided in the middle of the pipe 37. This is a valve that blocks the flow path of the pipe 37 and blocks dry superheated steam supplied to the pipe 34 (that is, the steam flow path pipe 2c).

  Reference numeral 80 denotes a control device, which is a steam generator 3, a superheater 4, a main exhaust valve 13, a sub exhaust valve 14, a conduction motor 26, a pressure control valve 51, a stop valve 53, a stop valve 62, a stop valve 64, and a stop valve. 68, the stop valve 69 is centrally controlled.

(Process for treating organic matter of the present invention)
Hereinafter, the organic material treatment method of the present invention will be described. First, the lid 1b is opened, and an organic substance to be decomposed is input from the input port 1a. The organic matter decomposed by the organic matter treatment apparatus of the present invention includes woody biomass, livestock excrement, sewage sludge, municipal waste, food waste, livestock and fish bones and internal organs, plastics such as plastic syringes, RPF, etc. Includes waste, industrial waste, and other organic matter such as shrimp, straw shells and grains. That is, it is other than metals and ceramics (broadly defined ceramics including glass and ceramics).

  Next, the main exhaust valve 13 and the sub exhaust valve 14 are closed to bring the sealed container 1 into a completely sealed state (an airtight state). Further, the stop valve 62 and the stop valve 69 are closed to form a flow path in which the heated steam generated by the steam generating device 3 flows from the pipe 34 to the steam flow path pipe 2c. In this state, the conduction motor 26 is operated to rotate the stirring blade member 2, and the water vapor generating device 3 is further operated to supply the heated water vapor to the steam flow path pipe 2c. Then, heated steam is discharged into the sealed container 1 from the steam discharge pipe 2d. Since the inside of the sealed container 1 is sealed, the pressure in the sealed container 1 increases to a pressure at which the safety valve 16 operates. In the present embodiment, the safety valve 16 operates at 1.8 MPa. When the safety valve 16 is activated, the air in the sealed container 1 is discharged to the outside along with the water vapor from the safety valve 16. For this reason, the inside of the airtight container 1 becomes a low oxygen or oxygen-free atmosphere.

  The hermetic container 1 has a high temperature of 140 ° C. to 180 ° C. and a high pressure of 1.8 MPa (18 times the atmospheric pressure). The organic matter in the sealed container 1 is heated by the latent heat and sensible heat that the heated steam has. Under high temperature and high pressure, the organic matter is stirred and decomposed by the blade portion 2b. Since the inside of the sealed container 1 is high temperature and high pressure, subcritical water is generated, and organic substances are dissolved and hydrolyzed by the hydrothermal reaction of this subcritical water. For example, cellulose and starch are converted into glucose, and protein is converted into amino acids. It is decomposed to lower the molecular weight, and the solid content is liquefied. For this reason, even large organic substances such as cow heads can be decomposed. As described above, since the inside of the sealed container 1 is in a low oxygen or oxygen-free state, the organic matter in the sealed container 1 is not oxidized. Since the organic substance being decomposed is stirred by the blade portion 2b, the organic substance is uniformly decomposed uniformly. Although depending on the nature and amount of the organic substance to be treated, the organic substance is decomposed with stirring for 10 minutes to 1 hour.

  When the organic matter is sufficiently decomposed, the main exhaust valve 13 is opened and the inside of the sealed container 1 is brought to substantially normal pressure (atmospheric pressure). Further, the stop valve 53 is closed and the stop valve 62, the stop valve 68, and the stop valve 69 are opened, and the water vapor generating device 3 is connected to the pipe 31, the pipe 33, the pipe 36, the superheater 4, the pipe 37, the pipe 34, A flow path communicating with the steam flow path pipe 2c is formed. The electric conduction motor 26 is operated to rotate the stirring blade member 2. Further, the steam generator 3 is operated to supply heated steam to the superheater 4. The dry superheated steam generated by the superheater 4 flows into the steam channel pipe 2c and is discharged into the sealed container 1 from the steam discharge pipe 2d.

  Although the main exhaust valve 13 is open, dry superheated steam is continuously discharged from the vapor discharge pipe 2d into the sealed container 1, so that outside air enters the sealed container 1 from the main exhaust valve 13. In the closed container 1, a low oxygen or oxygen-free atmosphere is maintained.

  The decomposed organic matter is heated by a great amount of latent heat contained in the dry superheated steam, and moisture contained in the decomposed organic matter is vaporized and discharged from the main exhaust pipe 11. As described above, since the inside of the dense container 1 is in a low oxygen or oxygen-free atmosphere, the organic matter during the drying process is not oxidized. Since the organic substance during the drying process is stirred by the blade portion 2b, the organic substance is uniformly and uniformly dried. Although depending on the nature and amount of the organic matter to be treated, the organic matter is dried with stirring for 10 minutes to 1 hour.

  When the organic matter is sufficiently dried and the treatment of the organic matter is completed, the secondary exhaust valve 14 is opened, the lid 1d is opened, and the treated organic matter is discharged from the discharge port 1c. The reason why the lid 1d is opened after the follower exhaust valve 14 is opened in this manner is that the main exhaust valve 13 is closed due to a failure or the like, and the inside of the sealed container 1 is at a pressure higher than normal pressure. This is because the organic matter after the treatment is ejected from the discharge port 1c.

  In the present embodiment, the stirring blade member 2 is continuously rotated with the lid 1d opened, and the processed organic matter is discharged from the discharge port 1c.

  In the present invention, since heated steam and dry superheated steam are discharged into the sealed container 1 from the steam discharge pipe 2d attached to the spindle 2a, the heated steam and dry superheated steam are uniformly distributed while stirring the organic matter. It is possible to supply the organic matter, and the organic substance decomposition process and the drying process can be promoted and can be performed in a short time and reliably.

  The organic substance processed by the organic substance processing apparatus 100 of the present invention is in the form of powder and has a low molecular weight, and therefore does not absorb moisture. This is because the composition of the organic matter is changed to a state where the treated organic matter is more stable when it does not absorb moisture in the atmosphere. The moisture content of the organic matter treated with the organic matter treating apparatus 100 of the present invention is 50% to 5%, and the state is maintained at a low moisture content without absorbing moisture, so that microorganisms can act. In addition, the organic matter after processing does not ferment or rot. For this reason, it can be used as livestock feed when treated with garbage, which could only be used as fertilizer, and can be stored for a long time even if it is not a special stockyard. Become.

  When the fish head / bone / built-in, which is discharged after dismantling the fish, is treated with the organic matter processing apparatus 100 of the present invention, it becomes powdery and can be used as food for fry.

  In addition, when shellfish shells such as shrimp and salmon are processed with the organic matter processing apparatus 100 of the present invention, it is possible to produce a health food containing a large amount of nutrients beneficial to the human body such as amino acids such as powder. It becomes.

  Although the present invention has been described with reference to the most practical and preferred embodiments at the present time, the present invention is not limited to the embodiments disclosed herein.
