Description

  The present invention relates to a novel apparatus and method for continuously heating a raw material to be heated. In particular, the present invention relates to an apparatus and method suitable for processing liquid-containing materials, and further liquid-containing organic waste, such as dry carbonization (dry distillation) / oilification, and other solid-liquid separation.

  Here, the “liquid-containing” includes not only a liquid phase that has been separated but also a state in which a liquid component is dispersed and held in a solid phase component. The representative “liquid component” is “water”, but also includes “solvent”, “oil”, and other various organic substances that can be liquefied from room temperature to less than 100 ° C.

  Liquid-containing organic waste includes various sludge, human feces, livestock excreta, okara, food waste, food residues, wood / plastic / rubber wastes, bandages, gauze, diapers Including medical waste.

  Here, the case where dry carbonization is performed using liquid organic waste as a raw material will be mainly described as an example, but the present invention is not limited thereto. That is, each treatment of drying or solid-liquid separation can be performed using a liquid-containing inorganic waste such as a paint waste as a raw material. Furthermore, it is also possible to carbonize / pyrolyze a dried product that is difficult to say a liquid-containing processed product or a heated melt of plastic or rubber.

  Conventional drying carbonization equipment (continuous heat treatment equipment) has a separate equipment for drying and carbonization, or requires a gas cooling tower or bag filter. It was not obtained. There is also a method of burning some raw materials in the carbonization equipment, but this caused a lot of ash, and it was difficult to obtain good quality charcoal (distilled product).

  Organic waste such as various types of sludge, human feces, livestock manure, okara, food waste, food residues, etc. can be dried and reused as fertilizers, but other wood-based / plastic-based / rubber-based wastes and the above-mentioned medical treatment Waste cannot be reused in that way.

  Therefore, it is conceivable to carbonize them together. For this reason, organic carbonization devices are on the market, that is, are marketed.

  However, these carbonization equipment is a separate means for dewatering and drying treatment means (drying equipment) and dry distillation means (carbonization equipment) in hydrous waste, and both drying equipment and dry distillation (carbonization) equipment are required. Met. Further, usually, a gas cooling tower and a bag filter are required, the apparatus is complicated, and it is difficult to obtain a high-quality processed product (carbide or carbonized product).

  In the carbonization apparatus, a part of the object to be processed is burned and steamed, but this is because it is difficult to obtain high quality carbides because of the large amount of ash.

  These techniques describe what the inventors have observed on-site and other companies' products, and are not specifically described in prior art documents.

In addition, although it does not affect the inventiveness of the present invention, as prior art documents related to the dry carbonization method and apparatus of the present invention, there are Patent Documents 1 to 3 etc. previously proposed by the present inventors themselves. To do.
JP 2000-320967 A (claims, etc.) JP 2004-66216 A (Claims etc.) Japanese Patent Laid-Open No. 2004-243281 (Claims etc.)

  In view of the above, the present invention is not conventionally capable of drying a liquid-containing object to be processed (heated object) and, if the liquid-containing object to be processed is an organic substance, appropriate carbonization or oiling, etc. It is an object (problem) to provide a continuous heat treatment apparatus and a continuous heat treatment method having a novel configuration.

  The continuous heat processing apparatus of this invention solves the said subject by the following structure.

The continuous heat treatment apparatus of the present invention includes a heat treatment chamber for heat-treating a raw material to be heat-treated, a raw material supply means for continuously supplying the raw material to the heat treatment chamber, and discharging the heat-treated product A continuous heat treatment apparatus comprising a discharging means for
In the heat treatment chamber, a plurality of heating plates each having a circular outer periphery or a circular inscribed shape are provided,
Disposing a grinding member and a scraping moving member that rotate relative to the upper surface of each heating panel,
The scraping moving member is a first scraping moving member that moves the raw material alternately from the outside to the inside in the upper and lower stages, or a second scraping moving member that moves the inner side to the outside. Between the boards, there is a transfer space in which the raw material can be dropped and transferred from the upper stage to the lower stage.

The method of the present invention is a method of heat-treating a raw material that is a liquid-containing object to be treated (an object to be heated),
A heating plate having a plurality of round or circular inscribed shapes is provided above and below in the heat treatment chamber, and the liquid-containing raw material is continuously supplied to the center or outer peripheral side of the uppermost heating plate, and the raw material is heated. While grinding on the board, move it in the direction opposite to the supply position and feed it sequentially onto the lower heating board to move the raw material from outside to inside or from inside to outside on the top surface of the heating board. However, it is characterized in that continuous heat treatment is performed, and the heat treatment chamber is continuously discharged.

  A more specific form is as follows.

  The continuous heat treatment apparatus of the present invention with a fixed heating plate has two kinds of large and small heating disks (heating plates) arranged alternately from above in a normal pressure or reduced pressure heat treatment chamber, and a grinding blade ( (Scouring member) and scraping moving blade (scraping moving member) are attached, so that the raw material is moved from the inside to the outside in the small disk, from the outside to the inside in the large disk, and sequentially moved from the top to the bottom by grinding and scraping movement. In this configuration, the raw material is continuously heated.

  The large and small disks have a jacket (double wall) structure, and a heat medium such as hot air, steam, or hot water is allowed to pass through the jacket, or heating of an electric heater, burner (gas / oil), etc. Arrange the equipment.

  Supply (input) of the raw material (processed product) to the apparatus is performed while shutting off the air when the heat treatment is performed in a sealed state (including not only reduced pressure / pressurization but also normal pressure). Although it may be supplied through a rotary valve, the raw material supply pipe (which may be replaced with a screw conveyor or a plunger as appropriate) is filled with the raw material itself and supplied by pressing, particularly from below onto the heating platen. Thus, it can be supplied in a self-sealing manner.

  Similarly, it is desirable that the product (processed product) can be discharged (removed) from the apparatus while the air is shut off.

  It may be carried out via a rotary valve or a double valve, but it may also be discharged while filling the screw conveyor with the product.

  In addition, the continuous heating apparatus of the present invention of the heating plate rotating type is mounted alternately in the vertical direction so that two kinds of large and small heating disks (heating plates) can be rotated through the double hollow rotating shaft in the main body of the device. In addition, a grinding blade (scouring member) and a scraping moving blade (scraping moving member) are fixed to the apparatus main body side, and a heat medium is passed from the inner tube side to the double hollow rotary shaft via a rotary joint. It is the structure which introduce | transduces into each heating panel and discharges to the outer tube side.

  The treatment of the generated gas (steam) in each of the above continuous heat treatment apparatuses is pyrolyzed and / or decomposed (purified) with a catalyst and exhausted. In addition, when the generated gas in the drying process or carbonization process is a useful (valuable) substance such as a solvent, hydrogen, carbon monoxide, lower hydrocarbon, etc., it is useful (valuable) by liquefaction (condensation) treatment using a condenser and a cold wrap. It can also be recovered as a product.

  If the raw material is a liquid such as waste oil or oil mud, or if it can be liquefied by heating, such as waste plastic, the air can be shut off by supplying the slurry pump into the device and continuously from the back side to the upper surface of the heating panel. (Sealed) supply becomes easy. If the raw material is gasified and cooled by a condenser, it can be used as a distilling oil / carbonizer.

  Furthermore, when the apparatus having the above configuration includes a hot air generating furnace or a thermal decomposition deodorizing furnace, when the water jacket method is adopted as the heat insulating method of the furnace, the vapor generated in the jacket is again returned to the hot air generating furnace. Or if it introduce | transduces into a thermal decomposition deodorizing furnace, it reheats with a heater, a heating vapor | steam is generated and it supplies in a heat processing chamber (dry carbonization chamber), heat processing (dry carbonization process) can further accelerate.

  In addition, a steam trapping pipe (collection pipe) is installed in the pyrolysis deodorization furnace, and when the raw material containing moisture (processed material) is dried, the steam generated from the raw material is captured and collected by the trapping pipe (collection pipe). Heat treatment (drying treatment) is promoted by generating heated steam through a heater and ejecting it again into the heat treatment chamber.

  The apparatus of the present invention may be a steam dryer that generates heated steam and ejects the heated steam into a heat treatment chamber (drying chamber).

  The heat treatment apparatus according to the present invention can be continuously operated by blocking the outside air, charging the raw materials, and taking out the processed products, can be installed in a vertically long three-dimensional structure, and can provide a compact and large processing capability.

  Also, scraping with the next scraping moving member (scraping wing) while thinly rubbing and grinding the okonomiyaki to a disk (heating plate) heated with a grinding wing (smashing member), Heat exchange is performed efficiently and smoothly by newly repeating rubbing and scraping with a rubbing blade, and dry carbonization of the raw material can be promoted.

  In addition, when the raw material is slid from inside to outside of the disk (heating plate) and crushed, the raw material is always stirred by repeated scraping, and there is no drying unevenness. It is subjected to heat treatment (dry carbonization, etc.).

  Hereinafter, some preferred embodiments of the continuous heat treatment apparatus of the present invention (hereinafter simply referred to as “heat treatment apparatus”) will be described with reference to the drawings. In the following description, the same reference numerals are assigned to the same reference numerals even if the same functional members are slightly changed, and the description thereof may be omitted in later embodiments.

  (1) What is shown to FIGS. 1-4 is embodiment which applied the heating-panel fixed-type heat processing apparatus of this invention to the dry carbonization processing apparatus.

  In the dry carbonization treatment chamber (heat treatment chamber) 1 in which the outer wall or inner wall is heat-insulated, fixed large and small disks (heating plates) 2, 3 (3A) having a donut shape with a jacket structure are alternately placed from above. This is a fixed heating panel type arranged in multiple stages.

  The large disk 2 is larger than the small disk 3 (3A) in both outer and inner circumferences, and the small disk 3 (3A) is smaller in outer circumference and inner circumference than the large disk 2. For example, in both disks 2, 3 (3A), the difference between the inner diameter and the outer diameter is about 30 mm to 100 mm.

  A rotating shaft 4 is held by upper and lower bearings 5 that keep hermetically sealed with outside air at the center of the central space of the disks 2 and 3 (3A), and can be rotated by a drive motor 6. Individual grinding blades (scouring members) 7 and scraping moving blades (scraping moving members) 8, 8 </ b> A are held by a support rod 9.

  The disks 2, 3 (3A) are provided with one or more grinding blades (scouring members) 7 and scraping moving blades (scraping moving members) 8, 8A for one disk.

  As shown in FIG. 5, the grinding wings 7 are spaced apart by 2 to 10 mm from the upper surface 10 of the horizontally installed disks 2 and 3 and are inclined at an angle of 30 to 45 °. 9 is attached. The rubbing blade 7 has a saw-toothed cutting blade 13, and the raw material is crushed by the cutting blade 13 and is rubbed thinly on the disk.

  In addition, as a grinding member, what uses the rotating roller 100 of a structure as shown in FIG. 6 can also be used.

  The rotating roller 100 attached to the support bar 9 can be rotated by a bearing 101, and is rotated by the rotating roller 100 when the rotating shaft 4 rotates, and is ground and adhered to the disk upper surface 10. In order to improve the grinding action, the rotating roller 100 can be provided with a groove 100a. The depth of the groove 100a varies depending on the workpiece (raw material), but is preferably several mm to several cm. If the groove 100a is a thread groove (spiral groove), the raw material can be scraped and moved along the thread groove while being ground. The reference numeral “102” is a scraper that strips off deposits.

  In this way, the raw material 15 slid onto the large and small disks 2 and 3 (3A) is scraped and moved by the scraping moving blades 8 and 8A rotating in the direction of the arrow 14 by the rotating shaft 4, and the disks 2 and 3 ( The upper surface of 3A) is moved from outside to inside or from inside to outside in the direction of arrow 14 (see FIGS. 2 to 4).

  As shown in FIGS. 7 (a) and 7 (b), the scraper moving blade 8 disposed on the large disk 2 is angled with respect to the support rod 9 within a range of 30 ° to 60 ° as viewed from above. It is installed and attached to the upper surface 10 of the disk 2 at an angle of 20 ° to 45 °. The scraping moving blade 8 rotates in the direction of the arrow 14 to scrape and move the raw material 15 in the direction of the arrow 14 from the outside to the inside of the disk 2 while scraping the ground raw material 15.

  On the other hand, as shown in FIGS. 8 (a) and 8 (b), the scraping moving blade 8A arranged on the small disk 3 is opposite to the case of the large disk 2 with respect to the support rod 9 as seen from the plane. It is installed at an angle, and is attached to the upper surface 10 of the disk 3 at an angle similar to that of the large disk 2. The scraping blade 8A scrapes and moves the raw material 15 from the inside to the outside in the direction of the arrow 17 by the rotation in the direction of the arrow 14.

  A product discharge port 23 is provided in the vicinity of the outer peripheral wall 20 of the lowermost small disk 3A, and a product drop cylinder 24 having a rotary valve 25 at the bottom is attached to the product discharge port 23. The product can be discharged continuously while blocking outside air.

  The flow of the raw material on the heating plate in this heating plate fixing system is as follows (see FIGS. 2 to 4).

  The raw material 15 supplied to the upper surface 10 outside the large disk 2 in the uppermost stage is moved in the direction of the arrow 16 from the outside to the inside while being ground by the rotation of the grinding wing 7 and the scraping moving wing 8. Falls from the inner diameter wall 18 (FIG. 2). Then, it is received by the upper surface 10 on the inner side of the lower small disk 3, and this time, in the direction of the arrow 17 from the inside to the outside by the rotation of the grinding blade 7 and the scraping moving blade 8 </ b> A, It falls from the outer peripheral wall 20 and is received by the upper surface on the outer peripheral wall 21 side of the large disk 2 (FIG. 3). Thus, the movement in the direction of the arrow 16 and the arrow 17 is sequentially repeated to reach the product discharge port 23 in the lowermost small disk 3A, and from the product dropping cylinder 24 through the rotary valve (product discharge means) 25, The product (processed product) 26 is stored in a product container 27 (FIG. 4). Note that a fall prevention wall 3a is formed on the lowermost small disk 3A so that the product does not fall from the outer peripheral edge.

  In the case of carbonization, it is desirable that the product container 27 has a cooling jacket structure (not shown) as shown in FIG.

  In the present embodiment, the heat medium is hot air from the hot air generating furnace 33 by burner heating. The hot air 35 generated by the burner 34 enters the jacket portion 12 of the disks 2 and 3 (3A) through the hot air flow path 36 and heats the disks 2 and 3 (3A). The hot air 35 exiting the hot air flow path 36 of the uppermost disk 2 is introduced into an attached pyrolysis deodorizing furnace 37 and added to the heating of the deodorizing furnace 37 to generate a gas (steam or dry distillation gas) 38 generated from the raw material. Also, the air flows into the deodorizing furnace 37 and blows air 40 with a blower 39 to produce an ejector (jet) effect. The hot air 35 and the generated gas 38 are absorbed and thermally decomposed with a burner 41 to perform deodorization. The thermally decomposed pyrolysis gas (exhaust gas) 42 is exhausted from an exhaust cylinder 43.

  As fuel for the burners 34 and 41, kerosene, heavy oil, LP gas, city gas, and the like can be suitably used.

  In the embodiment shown in FIG. 9, in the embodiment shown in FIG. 1, the hot air generating furnace 33 has a water jacket 87 structure for heat insulation so that the fire resistance of the hot air generating furnace 33 is maintained. Then, the steam 88 generated in the hot air generating furnace 33 is passed through the heater 89 in the hot air generating furnace 33 through the pipe 89 and is injected into the processing chamber (heating processing chamber) 1 as the heating steam 92. Promotes dry carbonization.

  If the thermal decomposition and deodorization furnace 37 is insulated with a water jacket 87 and the heater 90 is installed in the furnace 37 and sprayed into the processing chamber 1 through the pipe 89, ventilation with hot air occurs and dry carbonization further proceeds.

  A water level maintaining tower 93 is connected to the lower portion of the water jacket 87 through a communication pipe 94. In the example, “96” indicates a ball tap, and “95” indicates a makeup water pipe.

  If the hot air generating furnace and the pyrolysis deodorizing furnace are used as a water jacket as in this embodiment, the apparatus can be manufactured at a lower cost than a ceramic heat insulating material or a cast heat insulating material. Moreover, since heated steam can be obtained, the hot air flow rate in the apparatus increases and the drying speed increases. Moreover, it becomes the same as that the activated carbonized product is heated with steam, and a porous carbonized product with many pores can be obtained. Since the heating steam of the water jacket is used, a separate heating source for obtaining the heating steam is not required, which contributes to energy saving.

  In the embodiment shown in FIG. 10, in the embodiment shown in FIG. 9, in the drying process, the pyrolysis deodorization furnace 37 is provided with a water collection pipe 97 for collecting steam generated from the raw material (processed object) 15, A heater 90 is connected to the water collecting pipe 97 so that heated steam 92 is generated and injected into the processing chamber 1.

  In the above-described embodiment, heating can be performed by putting steam into hot air and heating steam can be selected, and various heat sources can be selected depending on the installation location.

  Further, the disks 2 and 3 may be thin, and heat conduction can be enhanced, and the jacket structure provides strength and enables mass production as a standardized product.

  In the said embodiment, when it is set as an oxygen-free state and it is set as indirect heating, charcoal does not turn into ash. Further, by operating the blower in the pyrolysis furnace, the generated gas can be sucked by the ejector effect, and the inside of the apparatus can be slightly reduced in pressure.

  Also, it can be applied to everything from liquid to solid, regardless of the type of raw material.

In addition, when the specifications of this device are, for example, 6 stages of heating panels (upper surface area: 3.14 m ² ) with a diameter of about 2 m and heat treatment with hot air at 600 rpm and rotation speed of 5 rpm (min ^-1 ) The inventor has confirmed that an 80% sludge can be carbonized at 300 kg per hour.

  In the case of a steam type, if the vapor pressure is lowered, drying can be performed at a low temperature, and drying using waste water in an energy utilization system such as cogeneration (cogeneration) in the jacket of the heating panel is also possible. A wide range of applications is possible.

  Further, in the case of used activated carbon, the adsorbed substance is organic. Therefore, if the pyrolysis treatment is performed in the apparatus of the present invention, the activated carbon can be regenerated and can be used as a regenerated apparatus for activated carbon.

  In addition, what can be made into feed and fertilizer depending on the type of raw material, the heat treatment apparatus of this embodiment can be suitably used as a dryer, the dried product can be recycled into feed, fertilizer, etc. , Fuel, soil conditioner, humidity conditioner, filter agent, snow melting agent, compost, etc.

  In addition, it can be processed at low temperature without causing secondary pollution, and therefore, durability is increased and operation is easy, operation engineers are unnecessary, there is no danger, and safe and automatic operation is possible.

  (2) What is shown in FIG. 11 is an embodiment in which the heating platen-type heat treatment apparatus of the present invention is applied to an oil-forming / carbonizing apparatus when the raw material 15 is waste oil or oil mud.

  A screw conveyor 55 is arranged so that the raw material 15 can be pushed and fed from the back side of the upper surface 10 of the disk through the disk jacket portion 12 to the uppermost disk 2 by a screw. The outer cylinder of the screw conveyor 55 is heated by a heater 57 so that the solid material 15 such as waste rubber and waste plastic can be heated to such a degree that it liquefies. When a solid material such as waste rubber or waste plastic is used as a raw material, it is crushed to some extent (for example, about 10 to 20 mm) and put into the raw material hopper 54.

  Here, when the molten raw material is supplied from the back side (lower part) of the upper surface (processing surface) 10 of the disk 2, the screw pipe 55 a is filled with the raw material and pushed up to be supplied. For this reason, it is possible to continuously feed the raw material 15 in a state of being completely shut off from the outside air. Reference numeral “56” is a drive motor for the screw 55, and has an inverter control mechanism for controlling the input amount.

  As in the embodiment of (1) above, the input raw material 15 is oiled and carbonized while sequentially shifting from the upper disk (heating disk) 2 to the lower disk (heating disk) 3 (3A), Organic residue is carbonized.

  The oily smoke gas 38 from the raw material 15 passes through the gas outlet pipe 45, passes through the gas reformer 58 provided in the middle of the outflow pipe 46, enters the heat exchanger 61, and the gas 38 is cooled and the oil-water separation tank 62 is cooled. The oil and the oil are separated from each other to obtain a product oil 63.

  The off-gas 64 that has not been distilled enters the water-sealed tank 65 in a sealed state, and the off-gas 66 in the oil / water separation tank 62 also enters the water-sealed tank 65.

  The off-gas 67 in the water sealing tank 65 is blown to the pyrolysis deodorization furnace 37 by a blower 68 through a pipe and is thermally decomposed by a deodorization furnace burner 41.

  The gas reformer 58 is filled with a catalyst 59, and an electric heater 60 for increasing the catalyst efficiency is disposed on the lower side. As the catalyst in this case, quick lime, white clay, or zeolite can be preferably used.

  Reference numerals “69” and “70” denote a cooling water inlet and a cooling water outlet of the heat exchanger 61, respectively.

  In the case of waste plastics, it is gasified if it is thermally decomposed using this device, and high-quality oil or useful gas (hydrogen, carbon monoxide, methane, etc.) can also be obtained by heat exchange using a gas reformer. Can be expected.

  (3) What is shown in FIG. 12 is an embodiment of a drying carbonization apparatus (heat treatment apparatus) in which the heating means of the large / small disk (heating board) is directly used as a heating element in the heating board fixed type treatment apparatus. .

  This is a device that fills the jacket 12 of the large and small disks 2, 3 (3A) with a heating element 44, generates heat to heat the raw material, and dry carbonizes. Here, as the heating element, various electric heating elements such as an electric heater, a cast-in heater, a cartridge heater, a silicon carbide heater (siliconite) can be suitably used. In the case of an electric heating element, temperature can be easily controlled with a thermocouple and a temperature controller, and energy can be used without waste.

  The outer diameter wall 21 of the large disk 2 is set higher than the inner diameter wall 18, and the outer diameter wall 20 of the small disk 3 is set lower than the inner diameter wall 19, and even if the raw material 15 is liquid, the lower disk 3 ( Or, it does not flow out and fall in 2), and after being heated, it always falls over the outer diameter walls 18 and 20 by the action of the scraping moving blades 8 and 8A.

  In this embodiment, the gas (steam or dry distillation gas) 38 generated from the raw material 15 by heating the disks 2 and 3 (3A) passes through the gas outlet pipe 45, the outflow pipe 46, and the catalyst deodorization tower 48. In this configuration, exhaust is performed. And the air blower 39 is provided in the base part of the outflow pipe 46, and it is the structure which makes it blow 40 and discharge | emits the gas 38 more smoothly by the ejector effect. Further, the catalyst deodorization tower 48 is filled with a deodorization catalyst 47, and a heater (heating element) 49 for exhibiting a catalytic effect is disposed below the catalyst.

  The catalyst for deodorizing the catalyst is preferably platinum or titanium oxide, and a heating temperature of 250 to 350 ° C. is considered optimal.

  Further, in the present embodiment, the discharge of the product (processed product) 26 is performed by providing automatic valves 28 and 29 on the processed product dropping cylinder 24 instead of the rotary valve, and opening and closing the upper and lower valves alternately to shut off the outside air. However, it is the structure performed continuously.

  (4) What is shown in FIG. 13 is an embodiment of a steam-type dry carbonization apparatus capable of independently supplying large and small disk heating means in a processing apparatus with a fixed heating panel.

  That is, steam is used as a heating source that independently introduces steam 50 or heating steam 51 into the jacket 12 of the large and small disks 2, 3 (3A) to dry carbonize.

  The raw material 15 is not only fed from above, but also from the back side of the uppermost large disk (heating plate) 2 through the raw material supply pipe 55 such as a screw conveyor as in the case shown in FIG. It is good also as a structure which pushes in and supplies. Self-sealing by compression can be expected by pushing and feeding from the back side (lower side). Although not shown, the pushing can be performed with an extrusion screw or a plunger.

  In the illustrated example, the generated gas 38 treatment is performed in a catalyst deodorization tower 48, and the catalyst deodorization tower 48 is filled with a deodorization catalyst 47 as in the above-described embodiment, and a catalytic effect is provided below the catalyst. A burner 53 to be raised is arranged. Note that the symbol “52” is a steam drain.

  In the embodiment shown in FIG. 14, in the steam-type drying carbonization apparatus of the above-described embodiment, the heating steam 92 is generated by the heater 99 in which the electric heater 98 is built, and is injected into the disk jacket portion 12 and the processing chamber 1. It is the structure which makes it process.

  In this case, the heater temperature can be maintained at 600 to 750 ° C., and the steam having the original steam temperature of 100 to 120 ° C. can be changed to the heated steam 92 at 300 to 400 ° C. by the heater 99.

  Also in the steam type of this configuration, by using heated steam, high-temperature heated steam can be obtained even if the amount of steam is small, the processing speed can be increased, and the amount of steam drain can be saved. That is, with heated steam, the volume increase is 1000 to 1500 times, and the flow rate is increased. Therefore, when the wind blows, the rate of dry carbonization increases as the liquid evaporates and the laundry is dried quickly. Thus, dry carbonization can be performed in a short time.

  The gas 38 generated by heating the raw material 15 is discharged from the gas outlet pipe 45 and is not drained and brominated through the pyrolysis deodorization furnace or the catalyst deodorization tower as described above, though not shown.

  The embodiment shown in FIG. 17 has a configuration in which the steam 50 is heated by the heater 98 and blown to the upper side of the lowermost disk 74 in the rotary heating carbonization apparatus. In the present embodiment, carbonization of the raw material after drying is promoted by the above configuration.

  In this configuration, heating steam 92 is generated and processed by a heater 99 having a built-in heater 98.

  In addition, each said drying carbonization apparatus can be used also as a single function apparatus of a drying apparatus or a carbonization apparatus, if temperature control is carried out.

  (6) Next, the configuration and operating conditions of each member common to the above embodiments will be described.

1) Configuration and material of each member:
The heaters 90 and 99 (FIGS. 9, 14, and 17) are omitted in the drawing, but in order to increase the surface area, a multi-tube type honeycomb (honeycomb) shape is preferable. As a material of the heaters 90 and 99, heat resistant stainless steel can be suitably used.

  The outer wall material of the processing chamber 1 may be SS steel plate, but the disks 2, 3 (3A), 73, 74, etc. are preferably heat resistant stainless steel.

  The grinding blades 7 and 75, the scraping moving blades 8, 8A, 76, and 76A are preferably formed of a thin stainless steel plate having a thickness of about 1 to 3 mm. The blades 7, 75, 8, 8A, 76, and 76A are attached to the disk upper surface 10 with a gap of about 2 to 10 mm depending on the processing raw material. Although not shown in the drawings, the structure can be slid and adjusted depending on the type of raw material.

-As a heat insulating material of the processing chamber 1, the hot air generating furnace 33, and the thermal decomposition deodorizing furnace 37, a refractory caster or a ceramic fiber can be preferably used.
The rotation speed of the rotary shafts 4 and 71 is optimally 0.5 to 15 rpm, and it is desirable that the rotation speeds of the drive motors 6 and 85 are made variable by inverter control with the raw material 15.

  The temperature of the hot air 35 in the hot air generating furnace 33 differs depending on the type of raw material, but in the case of ordinary liquid organic waste, for example, considering the durability of the furnace, the source is 600 ° C. and passes through the hot air flow path 36. It is desirable that the heat is effectively utilized through the respective disks 2, 3 (3A) so that the uppermost stage is about 200 ° C.

  The pyrolysis temperature of the pyrolysis furnace 37 may normally be about 500 ° C. or higher. However, when a material containing chlorine is mixed in the raw material, dioxins can also be decomposed by keeping the residence time at 800 ° C. or higher for 2 seconds.

  -In the case of carbonization, the moisture and volatile organic matter contained in the heated steam raw material (object to be processed) are pulled out from the inside by the heater 99, and in the case of carbonization, the state is the same as the state of activation treatment, even at a low temperature. A carbonized product (dry-distilled product) having good pores can be obtained, and can be used as activated carbon or the like.

  In the case of carbonization with steam, the carbonization can be performed by reheating the steam to about 600 ° C. and putting it in the jacket (double wall).

  -The raw material can be ground with a cutting blade of a grinding blade (a grinding member), but a large solid is supplied after being crushed to a size of about 20 mm or less as a pretreatment. This is to promote heat treatment (dry carbonization) of the raw material.

  (7) The technical scope of the present invention is not limited to those described in each of the above embodiments, but extends to the following various modifications based on the description of the scope of claims. .

  -The shape of the doughnut-shaped heating plate is not limited to a circle, and may be any shape such as a circle inscribed shape, for example, a regular polygon, or a shape that is cut along each side of a circle or a regular polygon. The outer and inner shapes are not necessarily the same. When many small cuts are made, granulation can be expected there.

  -The number of stages of the heating panel can be set to one or more, preferably two or more, and can be designed to meet the required heat treatment capacity. By combining them, it is possible to design corresponding to the installation allowable space.

  It is possible to arrange not only heat insulating means but also heating means (for example, jacket heating means, electric heater) or temperature adjusting means on the peripheral wall of the processing chamber.

  The shape of the processing chamber is not limited to a cylindrical shape, and may be a rectangular tube shape. Furthermore, depending on the mode of the heat treatment, for example, a lower small diameter or an upper small diameter truncated cone or a truncated pyramid cylindrical shape It is also possible to do.

  -In each said embodiment, although the pyrolysis deodorizing furnace and the catalyst deodorizing tower are installed in the upper part of the processing apparatus main body, it is good also as horizontal installation according to an installation location. In this case, it is desirable that the connecting pipe is as short as possible.

  In each of the above embodiments, the processing chamber is a sealed type, but may not be a sealed type depending on the type of raw material and the mode of heat treatment.
