Description

  The present invention relates to a carbonization apparatus for producing carbide by drying organic matter by supplying superheated steam to the organic matter such as food waste.

  In recent years, while regulations on industrial waste have been strengthened, carbonization processing equipment that supplies superheated steam to organic substances such as food waste, food residues, plastics, and wood to perform carbonization, and effectively uses the resulting carbides. Various proposals have been made.

  For example, from the viewpoint of increasing energy efficiency when supplying superheated steam into the carbonization furnace, a carbonization processing apparatus is provided in which a heater that generates heat by energization is disposed inside the carbonization furnace, and the generated superheated steam is immediately introduced into the organic matter. It is disclosed (see Patent Document 1).

  However, the carbonization apparatus employs a so-called open type system in which the odor gas generated by the carbonization treatment of organic matter is decomposed and rendered harmless and then discharged to the outside of the apparatus. In the case of trouble in the decomposition system, odor gas is directly discharged to the outside of the apparatus, which is inconvenient when used indoors from the viewpoint of safety.

In addition, a carbonization apparatus is also disclosed in which excess water vapor generated in the carbonization furnace is once condensed and discharged to the outside of the apparatus. In the case of such a carbonization apparatus, odorous components contained in the condensed water are outdoors. There is a risk of leakage (see Patent Document 2). On the other hand, if condensate is not discharged outdoors, it is conceivable to provide a storage tank that accommodates the entire amount of condensate, but in such a case, the entire device becomes larger and there is a problem in securing the installation location when used indoors. is there.

  The present invention has been made in view of the above problems, and provides a carbonization apparatus capable of quickly performing carbonization of organic matter without causing odor gas generated from the organic matter to be discharged to the outside during operation. Main purpose.

  In order to achieve the above object, the carbonization apparatus of the present invention normally heats a water tank that contains water, a boiler that vaporizes water transferred from the water tank, and water vapor that is transferred from the boiler. A heating element that generates superheated steam at a pressure, and a carbonization furnace that performs carbonization treatment by supplying superheated steam generated from the heating element to an organic substance, and is circulated and connected to the carbonization furnace via a pipe, A pyrolysis device that continuously pyrolyzes odor gas generated from the organic matter as the treatment progresses, and is connected to the carbonization furnace and the water tank via a pipe line, and the carbonization as the carbonization treatment progresses. The excess water vapor generated in the furnace is cooled, the obtained excess water is deodorized, and the filtrate produced thereby is accommodated. When the filtrate is contained in a predetermined amount, the prescribed amount of filtrate is Surplus to be transferred to the tank Characterized in that it comprises a steaming means.

  Here, in the present invention, “organic matter” refers to an organic matter that is carbonized by the present apparatus, regardless of the presence or absence of moisture. Typical organic substances include, for example, organic substances having a high water content such as food waste and food residues, organic substances having a low water content such as plastics and waste tires, and organic substances having a wide water content such as wood. It is done. In the present invention, “surplus steam” refers to a steam component that is generated in the carbonization furnace and contains odor. Such surplus steam is generated when organic matter containing water is processed, both generated from the organic matter as carbonization progresses, and generated when the inside of the carbonization furnace reaches a saturated steam pressure by continuous supply of superheated steam. including. Moreover, when processing the organic substance which does not contain a water | moisture content, it means what generate | occur | produces when the inside of a carbonization furnace reaches a saturated vapor pressure by continuous supply of superheated steam.

  The carbonization furnace includes a horizontally placed cylindrical carbonization furnace main body and a lid body detachably attached to the left and right ends thereof, and each inner wall surface of the lid body generates heat by energization. The heating element is bent and attached.

  Further, the water tank is characterized in that when filtered water is transferred to the water tank, the supply of water from the water source to the water tank is stopped and the stored filtered water is preferentially transferred to the boiler. And

  According to the carbonization apparatus of the present invention, the odor gas generated with the carbonization treatment of the organic matter is thermally decomposed by the thermal decomposition apparatus, and the obtained thermal decomposition product is repeatedly supplied into the carbonization furnace. The amount of odorous gas in the inside is significantly reduced. Further, surplus water vapor generated with the carbonization treatment of the organic matter is also liquefied by the surplus water vapor treatment means, and the odor component contained in the obtained surplus water is deodorized. For this reason, the odor gas (component) generated from the organic substance is surely deodorized inside the carbonization processing apparatus, and thus is not discharged outside the carbonization processing apparatus during the carbonization processing.

  In addition, superheated steam is directly supplied to the organic matter by the heating element provided inside the carbonization furnace, and the decomposition product obtained by the thermal decomposition action by the thermal decomposition apparatus is continuously supplied to the carbonization furnace at a very high temperature state. Since it is supplied, the inside of the carbonization furnace is always maintained at a high temperature suitable for carbonization. For this reason, the carbonization process of organic substance can be performed rapidly.

  Furthermore, the surplus steam generated in the carbonization furnace with the progress of the carbonization process is liquefied and deodorized by the surplus steam treatment means, then returned to the water tank as filtered water and repeatedly used as a source of superheated steam. Is done. For this reason, a large-capacity filtered water storage tank is not required, and the carbonization apparatus can be downsized compared to the conventional case. In the surplus steam treatment means, when a predetermined amount of filtered water is stored, a predetermined amount of filtered water is transferred to the water tank, so that the operation control of the carbonization apparatus can be performed safely and easily.

  Next, the present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 is a schematic configuration diagram showing an example of a carbonizing apparatus 1 according to the present invention. Moreover, the case where the food residue containing a water | moisture content as an organic substance is used is demonstrated as an example.

  The carbonization treatment apparatus 1 includes a water tank 2, a boiler 3, a carbonization furnace 4, a thermal decomposition apparatus 5, excess steam treatment means 6, a pump 61, and the like. Regarding the carbonization process of the organic matter by the carbonization apparatus 1, first, after putting the organic matter from the inlet 11 of the carbonization furnace 4 and sealing the carbonization furnace 4, the water taken from the water tank 2 is converted into steam by the boiler 3. By passing this steam through the heating element 12 provided inside the carbonization furnace 4, normal pressure superheated steam is continuously generated. Next, normal pressure superheated steam generated from the heating element 12 is supplied to the organic material to perform carbonization. Here, in supplying superheated steam to the organic matter, it is preferable to generate superheated steam at 350 to 700 ° C. from the viewpoint of promptly carbonizing the organic matter.

  As the carbonization process proceeds, odorous gas is generated from the organic matter. The odor gas is transferred to a thermal decomposition apparatus 5 that is circulated and connected to the carbonization furnace 4 through a pipe line. The thermal decomposition apparatus 5 is a heating element controlled to a temperature of 800 to 1300 ° C. The odor gas is thermally decomposed when passing through the thermal decomposition apparatus 5, and the generated decomposition product is returned to the carbonization furnace 4 again. The thermal decomposition apparatus 5 is continuously operated during operation of the carbonization apparatus 1. For this reason, the odor gas generated in the carbonization furnace 4 is reliably pyrolyzed and returned to the carbonization furnace 4 when passing through the thermal decomposition apparatus 5, and the newly generated odor gas is also pyrolyzed in the same cycle. Will receive. Here, from the viewpoint of increasing the efficiency of thermal decomposition of odor gas, a gas transfer means 22 (for example, a sirocco fan) may be provided between the carbonization furnace 4 and the thermal decomposition apparatus 5. That is, if the gas transfer means 22 is used, the odor gas generated in the carbonization furnace 4 is forcibly transferred to the thermal decomposition apparatus 5, so that the odor gas can be efficiently decomposed.

  Further, as the carbonization process proceeds, surplus water vapor (evaporated vapor, odor, etc.) is generated from the organic matter. This surplus steam is transferred to surplus steam treatment means 6 connected to the carbonization furnace 4 and the water tank 2 via a pipe line. The surplus steam first passes through the condenser 31 constituting the surplus steam treatment means 6 and is liquefied by cooling to be surplus water. Subsequently, this surplus water is introduced into the filtrate tank 41, where it is deodorized, and the obtained filtrate is accommodated. When a predetermined amount of filtered water is stored, the pump 61 is activated and a predetermined amount of filtered water is transferred to the water tank 2, and the transferred filtered water is transferred to the boiler 3 to generate superheated steam. As used repeatedly. Here, when it is desired to increase the purity of the water transferred from the filtrate water tank 41 to the water tank 2, a water purifier 62 may be provided between the filtrate water tank 41 and the water tank 2.

  The operation of the carbonization apparatus 1 is performed in the above-described process, and when the carbonization of the organic matter proceeds sufficiently, the operation of the carbonization apparatus 1 is terminated. After the operation is completed, the carbonized carbide is recovered from the discharge port 13 of the carbonization furnace 4.

  According to the carbonization apparatus 1, the odor gas generated in association with the carbonization process of the organic matter is thermally decomposed by the thermal decomposition apparatus 5, and the obtained decomposition product is repeatedly supplied into the carbonization furnace 4. The amount of odorous gas in 4 is significantly reduced. Furthermore, surplus water vapor generated with the progress of carbonization of the organic matter is also liquefied by the surplus water vapor treatment means 6, and the odor components contained in the obtained surplus water are deodorized. For this reason, since the odor gas (component) generated from the organic substance is surely deodorized inside the carbonization processing apparatus 1, it is not discharged outside the carbonization processing apparatus 1 during the carbonization processing.

  Further, superheated steam is directly supplied to the organic matter by the heating element 12 provided inside the carbonization furnace 4, and the decomposition product obtained by the thermal decomposition action by the thermal decomposition apparatus 5 is in a very high temperature state. Therefore, the inside of the carbonization furnace 4 is always maintained at a high temperature suitable for carbonization. For this reason, the carbonization process of organic substance can be performed rapidly.

  Further, the surplus steam generated from the organic matter as the carbonization process proceeds is liquefied and deodorized by the surplus steam treatment means 6 and then returned to the water tank 2 as filtered water and repeatedly used as a source of superheated steam. Is done. For this reason, the large capacity filtered water tank 41 becomes unnecessary, and the carbonization apparatus 1 can be reduced in size compared with the past. Moreover, in the said excess steam processing means 6, when a predetermined amount of filtrate water is accommodated, since a predetermined amount of filtrate water is transferred to the said water tank 2, operation control of the carbonization processing apparatus 1 can be performed safely and easily. it can.

  Then, each structural member which comprises the carbonization processing apparatus 1 mentioned above is demonstrated. FIG. 2 is a schematic configuration diagram showing an example of the internal structure of the carbonization furnace 4. In the carbonization furnace 4, lid bodies 15, 15 are detachably attached to left and right ends of a cylindrical carbonization furnace main body 14 placed horizontally by a plurality of bolts (not shown), and are attached to inner wall surfaces of the lid bodies 15, 15. Are provided with heating elements 12 and 12, respectively, and partition plates 20 and 20 are provided slightly closer to the center than the heating elements 12 and 12, respectively. The heating element 12 is a tubular body that generates heat when energized, and is bent and attached in a spiral shape (see FIG. 3). Specifically, starting from the introduction portion 12a slightly above the center of the lid body 15 for introducing water vapor from the outside, the lid body 15 is attached in a spiral shape toward the periphery of the lid body 15, and the lower end of the lid body 15 is near the lower end. It is set as the discharge part 12b. The heating element 12 can freely adjust the heat generation temperature according to its length and the amount of power supplied. For example, a known pipe heater made of SUS can be suitably used. The partition plate 20 may be configured so that the organic matter inside the carbonization furnace 4 does not come into contact with the heating element 12 and does not hinder the circulation of superheated steam discharged from the heating element discharge portion 12b. A plate material made of a large number of openings (punching metal) is preferably used.

  The organic substance charged into the carbonization furnace 4 is almost in the lower part of the carbonization furnace 4 during the operation of the carbonization treatment. For this reason, by attaching the heating element 12 in a spiral shape and disposing the discharge portion 12b of the normal pressure superheated steam near the lower end of the lid 15, superheated steam at the optimum temperature according to the organic matter to be treated can be easily supplied. Since the superheated steam can be directly supplied to the organic matter from a closer distance, the carbonization can be performed quickly. The carbonization treatment time has a certain range depending on the capacity of the carbonization furnace 4, the type of organic matter, the water content, and the amount of treatment, but it cannot be generally stated. When it is set to 1/2 to 1/3, it is usually about 1 hour to about 3 hours.

  According to the carbonization furnace 4 configured as described above, since the lid 15 is detachably attached to the left and right of the carbonization furnace main body 14, the lid 15 can be removed as compared with the case where the lid 15 is attached up and down. Easy to do. For this reason, maintenance, cleaning, and the like of the components inside the carbonization furnace 4 can be easily performed. In addition, as long as the heat generating body 12 is attached to the cover body 15 compactly, the attachment form is not limited to a spiral shape, For example, a linear form, a serpentine form, a spiral form, a U-shape, or a combination form thereof may be used. Good. Further, as long as the inside of the carbonization furnace 4 can be maintained at an atmospheric temperature that favorably promotes the carbonization treatment, the heating elements 12 and 12 attached to the left and right lid bodies 15 and 15 of the carbonization furnace main body 14 do not always need to generate heat, It is also possible to generate heat alternately every time.

  Moreover, in this invention, you may make it advance the carbonization process of organic substance efficiently by providing a stirring means inside the carbonization furnace 4 as needed. Such a stirring means preferably has a function of repeatedly raising and dropping the organic matter so as to scoop up the organic matter while collecting the organic matter staying at the bottom of the carbonization furnace 4 from the left and right ends near the center. As the stirring means having such a function, for example, the rotating shaft 16 disposed substantially horizontally passing through the central portions of the left and right lids 15 and 15, and one end connected to the rotating shaft 16 and the other end is a carbonization furnace. And a support shaft 17 extending toward the inner peripheral wall surface, and a substantially L-shaped stirring blade 19 having a plate-like blade 18 connected to the support shaft 17 is preferable (FIG. 4). reference). The stirring blade 19 has a support shaft 17 on a portion of the rotating shaft 16 penetrating the carbonization furnace 4 that is located near the left and right ends of the carbonization furnace (a portion closer to the center than the partition plate 20 in FIG. 2). The two blades 18 and 18 are connected to each other, and the base end portions of the blades 18 and 18 are arranged in a non-linear manner and slightly spaced apart from each other (see FIG. 4).

  By arranging the two stirring blades 19 and 19 so as to face each other, the organic matter is first collected toward the blades 18 and 18 near the center at the bottom of the carbonization furnace 4 as the rotating shaft 16 rotates. It is done. Then, the blades 18, 18 are rotated upward along the inner peripheral wall surface of the carbonization furnace 4, so that the organic matter is lifted so that the blades 18, 18 are moved along the inner peripheral wall surface of the carbonization furnace 4. Then, the organic matter falls to the bottom of the carbonization furnace 4 by rotating downward. As described above, when the organic matter is repeatedly lifted and dropped, the organic matter is easily dispersed, so that superheated steam can be supplied over the entire organic matter, thereby efficiently performing the carbonization treatment of the organic matter. Can proceed. The number of the stirring blades 19 to be used is not particularly limited as long as the organic substance can be effectively carbonized, but a plurality of sets of stirring blades may be used in addition to the one set shown in FIG.

  The carbonization furnace 4 shown in FIG. 2 to FIG. 4 is a batch type in which a predetermined amount of organic matter contained therein is discontinuously carbonized, but the carbonization furnace used in the present invention is not necessarily limited to the batch type. From the viewpoint of increasing the amount of organic matter to increase the efficiency of carbonization treatment, the organic matter is continuously supplied to the carbonization furnace to perform carbonization treatment, and the carbonized carbide is continuously discharged from the carbonization furnace. An expression can also be adopted. Such a continuous carbonization furnace can be configured by providing a transport means (for example, a belt conveyor) for transporting an organic substance charged into the carbonization furnace to a discharge port.

  The structure of the thermal decomposition apparatus 5 is not particularly limited as long as the odor gas generated in the carbonization furnace 4 can be thermally decomposed at 800 to 1300 ° C. From the viewpoint of facilitating temperature control, for example, nichrome inside. A ceramic heater provided with a wire is preferably used. In this case, what is necessary is just to mount | wear so that a part of the outer side of the pipe line through which an odor component passes may be wrapped from the outside. The above temperature is set as a temperature at which pyrolysis can be reliably performed even when dioxin is contained in the generated odor gas.

  FIG. 5 is a schematic configuration diagram showing an example of the surplus steam treatment means 6. The condenser 31 constituting the surplus steam treatment means 6 has a substantially cylindrical cooling pipe 32 and a cold water tank 33 connected to each other via a water conduit 34 and a drain pipe 35, and surplus steam generated in the carbonization furnace 4 The drain pipe 21 passing therethrough penetrates the left and right end faces of the cooling pipe 32 along the axial direction. A plurality of circular radiating fins 36 slightly smaller than the inner diameter of the cooling pipe 32 are attached to the drain pipe 21 inside the cooling pipe 32 at a predetermined interval perpendicular to the axial direction of the cooling pipe 32. The cylindrical portion of the cooling pipe 32 is provided with a plurality of through holes at predetermined intervals along the axial direction, and the water guide pipe 34 is disposed on the outer surface of the cylindrical portion of the cooling pipe 32 along the through holes. The spray nozzle 37 branched from the water conduit 34 is inserted into the cooling pipe 32 through the through hole. More specifically, the injection nozzle 37 includes a cylindrical nozzle base portion 37a and a cold water injection nozzle portion 37b provided at a base end portion of the injection nozzle 37. The nozzle base portion 37a branches from the water conduit 34 and the through hole is formed. The nozzle part 37b is arrange | positioned inside the cooling pipe 32 (refer FIG. 6). One end of the drain pipe 35 is connected to the lower left end of the cooling pipe 32 and communicates with the inside of the cooling pipe 32.

  Cold water of about 5 ° C. is stored in the cold water tank 33, and by driving a pump 38 interposed in the water conduit 34, this cold water is injected at a predetermined flow rate through the water conduit 34 and further branched from the water conduit 34. It is introduced into the cooling pipe 32 through the nozzle 37. Then, cold water is sprayed from the spray nozzle 37 toward the drain pipe 21, whereby excess water vapor in the drain pipe 21 is liquefied, and preferably is made into surplus water at around 10 ° C. and passes through the cooling pipe 32. The water that hits the drain pipe 21 and falls to the bottom of the cooling pipe 32 is returned to the cold water tank 33 through the drain pipe 35 and cooled again to about 5 ° C. in the cold water tank 33, and then the above cycle is repeated. Here, the radiating fin 36 is used for efficiently cooling the drain pipe 21 introduced into the cooling pipe 32, but in order to cool the drain pipe 21 more efficiently, the circular radiating fin 36 is used. A large number of small holes may be provided in (see FIG. 6). The cooling method of the drain pipe 21 inside the cooling pipe 32 is not limited to the method of injecting cold water to the drain pipe 21 as described above. For example, the cooling water is circulated while filling the cooling pipe 32 with the cold water. A scheme can also be used. In the present invention, a thermal decomposition apparatus similar to the above-described thermal decomposition apparatus 5 may be interposed between the carbonization furnace 4 and the condenser 31 as necessary. By providing such a thermal decomposition apparatus, it is possible to efficiently thermally decompose the odor contained in the surplus water vapor generated with the progress of the carbonization treatment in a gaseous state.

  Next, the filtered water tank 41 constituting the surplus steam treatment means 6 will be described with reference to FIG. The filtrate water tank 41 is composed of a box body that is surrounded on six sides by an upper surface, a side wall, and a lower surface, and an end portion of a drain pipe 21 is connected to the upper part of the box body and discharged from the drain pipe 21. A box-shaped first filtration unit 42 surrounded by six walls that can store a predetermined amount of surplus water is provided, and surplus that has passed through the first filtration unit 42 below the first filtration unit A box-shaped second filtration unit 43 is provided in which six surfaces capable of containing water are surrounded by walls. Openings 44 and 45 are respectively provided in the side walls constituting the box of the first filtration unit 42 and the second filtration unit 43, and adsorb odor components and pass excess water through these openings 44 and 45. Deodorizing members (for example, non-woven fabrics) 46 and 47 are attached, respectively. Moreover, below the 2nd filtration part 43, it is set as the filtrate water storage part 48 in which the filtrate which fell from the opening part 45 of the 2nd filtration part 43 is accommodated, This filtration water storage part 48 is a pipe line. 49 is connected to the first filtration unit 42 through 49, and is connected to the water tank 2 through a pipe 50. In addition, an air circulation part 51 is provided on the upper surface of the filtrate storage part 48 to allow air to enter and exit from the outside as appropriate. This air circulation part 51 is comprised from the cylindrical main-body part 51a through which air passes, and the deodorizing member 51b which adsorb | sucks the odor component with which the front-end | tip was mounted | worn.

  The filtered water tank 41 having the above-described configuration is operated as follows. First, the pump 52 provided in the pipe line 49 is driven, and a predetermined amount of cold water of about 5 ° C. is stored in the first filtration unit 42 in advance. When surplus water is discharged from the drain pipe 21, the surplus water diffuses into the cold water stored in advance, thereby shielding the odor component in the surplus water to some extent. When the amount of storage increases and reaches the height of the opening 44, excess water is stored in the second filtration unit 43 located below via the deodorizing member 46. The excess water contained at this time is adsorbed by the deodorizing member 46 at the beginning and contains almost no odor component. Next, when the amount of surplus water accommodated in the second filtration unit 43 increases and reaches the height of the opening 45, the surplus water is accommodated in the filtrate water storage unit 48 below through the deodorizing member 47. The Since the filtered water accommodated at this time contains almost no odor components originally contained, it is suitably used as a source of superheated steam. In this way, when the capacity of filtrate water increases and a water level sensor (not shown) has reached the reference water level, the pump 61 is driven to transfer a predetermined amount of filtrate water to the water tank.

  In the present invention, when filtered water is transferred to the water tank 2 as described above, the supply of water from the water source to the water tank 2 is stopped, and the stored filtered water is preferentially transferred to the boiler 3. It is preferable to do. In this way, when water is supplied from the water tank 2 to the boiler 3, the total amount of water supplied from the water source to the water tank 2 can be reduced by preferential use of the filtered water. That is, in the present invention, it is preferable that a predetermined amount of water is first transferred from the water source to the water tank 2 to generate superheated steam, and then the filtered water is transferred to the water tank 2 as described above for circulation. . It should be noted that the amount of water transferred from the water source first may be set as appropriate based on data obtained by performing a test in advance according to the type of organic matter, the amount of input, and the like.

  The carbonization treatment apparatus 1 configured as described above can quickly perform carbonization in less than 1 hour to 3 hours from organic matter having a moisture content of 50% or less to bean sprouts having a moisture content of 95 to 96%. Since odor gas is not discharged outside the apparatus during processing, it can be used not only outdoors but also indoors.
