Description

  The present invention generates organic waste by completely burning organic waste collected from livestock farms such as poultry farms and pig farms using an efficient combustion device, and this inorganic waste is used as fertilizer and water quality. The present invention relates to a manure and urine recycling plant, an animal manure and urine recycling system, and an animal manure and urine recycling method that can be provided to livestock farms, farms, and vegetable gardens as a modifier.

  In order to obtain a calorific value, a combustion apparatus for combusting various combustion agents has been proposed. In order to prevent the harmful gas generated by the reduction of fossil fuels and the combustion of fossil fuels in recent years, it is required to use organic waste such as biomass as a combustion agent.

  Many of such organic wastes that are attracting attention as a burning agent are mainly composed of, for example, manure from livestock from livestock farms. These livestock excreta are required to be treated appropriately in order to bring about bad odor pollution.

  On the other hand, it is required to construct a recycling system in various places in society, which does not dispose of waste as waste or unnecessary waste, but circulates it while serving various purposes.

  For the purpose of building such a recycling society, organic waste such as livestock excreta generated from livestock farms is expected to be used as a combustion agent for obtaining heat. However, when used as a combustion agent, organic waste becomes inorganic waste. If this inorganic waste is treated as it is in landfills, it will not lead to waste reduction and a complete recycling system cannot be realized.

  On the other hand, the various waste recycling systems that have been proposed are still difficult to obtain cost and social recognition, and cannot be established as appropriate businesses. If business feasibility is not expected, there is a problem that the corner recycling system cannot be established in society. In view of such a situation, a recycling system in which the starting point and the consequent point of waste coincide with each other is likely to solve the problem of cost and social understanding. This is because both the starting point and the consequent point are highly useful and increase the possibility of securing economic benefits.

  In such a situation, technologies for recycling waste while incineration have been proposed (see, for example, Patent Documents 1 to 5).

JP 2003-175382 A Japanese Patent Laid-Open No. 2005-98585 JP 2006-8424 A JP 2002-272293 A JP 2004-168589 A

  Patent Document 1 discloses a technique for separating and recycling a dam's drifting material into “large” and “small” items, and sorting and sorting each separated drifting material into livestock, fertilizer, and waste disposal. .

  However, Patent Document 1 differs from the starting point and the consequent point of waste, and cannot achieve complete circulation. In addition, since the stranded matter is simply separated as it is, there is a problem that it is difficult to reuse the organic waste as it is.

  Patent Literature 2 discloses a technique for burning livestock manure at a temperature of 900 ° C. or higher to obtain combustion ash and reusing the combustion ash as fertilizer.

  However, there is no specific disclosure of how to obtain combustion ash that can be reused as fertilizer. In addition, when waste is burned, it is in a so-called ash state, so that the combustion ash is diffused into the atmosphere, causing a problem of extra pollution. In addition, there is a problem in that the reference to the specific mode of reuse of combustion ash is insufficient.

  Patent Document 3 discloses a technique for burning cattle dung while subdividing the cow dung with a screw in order to efficiently burn livestock waste such as cow dung.

  However, there is a problem that the recycling of ash obtained by burning is not sufficiently disclosed, and a complete circulation type recycling system cannot be realized. In addition, there is a problem that combustion ash is scattered in the atmosphere due to the combustion of subdivided cow dung. In addition, complete combustion of cow dung is necessary for reuse, but there is no disclosure of a technique for realizing this.

  Patent Document 4 discloses a recycling system that transports chicken crush, crushes and dries it, burns the dried chicken dung, and reuses the processed product obtained by combustion as fertilizer.

  However, there is no disclosure of sufficient combustion required to be reusable as fertilizer. For this reason, there is a problem that the burned chicken manure is not reusable as fertilizer, there is no usefulness for the reuse side, and a recycling system for obtaining social recognition cannot be realized.

  Patent document 5 discloses the technique which incinerates garbage and reuses incinerated ash as fertilizer.

  However, there is a problem that it is difficult to secure a third party who purchases the incinerated ash for reuse because the starting point and the consequence point of the waste are different. There is also a problem that reuse cannot be established as a business because the cost of purchasing and burning waste is added to incinerated ash as fertilizer.

  In addition, Patent Document 5 does not disclose a technique for realizing sufficient combustion that can be reused as a fertilizer.

  As described above, the prior art has the following problems.

  (1) The starting point and consequences of waste do not match, and the ash that is to be reused cannot be reused while ensuring its usefulness and economy. So-called recycling type recycling cannot be realized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  (Embodiment 1)

First, the general outline of the recycling plant will be described.
(Overview)

  FIG. 1 is a schematic diagram of a recycling plant according to Embodiment 1 of the present invention. The recycling plant may be understood as a concept including all the elements shown in FIG. 1, or may be understood as a concept including only a part of the elements shown in FIG. In addition, although defined in terms of “plant” as a recycling plant, it is not necessary that all elements shown in FIG. 1 are installed in the same site, and each element shown in FIG. May be installed.

  Moreover, you may catch not with the concept with a recycling plant but with the concept with a recycling system provided with the element shown by FIG.

  The recycling plant 1 includes a first recovery unit 3 that recovers organic waste containing livestock manure discharged from the livestock farm 2, a combustion unit 5 that burns with a predetermined combustion device 6 using the organic waste as a combustion agent, And a second recovery means for recovering the inorganic waste obtained by the means 5 (the waste obtained by burning the combustion agent) as at least one of a fertilizer and a water quality modifier.

  Moreover, the recycling plant 1 may be provided with the shaping means 4 which shape | molds the organic waste collect | recovered by the 1st collection means 3 to a pellet shape as needed.

  The livestock farm 2 is a facility that keeps livestock, such as a poultry farm, a pig farm, and a meat farm, and discharges organic waste including livestock excreta excreted by the livestock. Organic waste containing livestock manure is a waste that is difficult to process for livestock farms, and has a problem that it cannot be processed even by landfill or purified water.

  The 1st collection means 3 collect | recovers the organic waste containing this animal manure.

  The first recovery means 3 performs a recovery operation so that the organic waste collected from the livestock farm using human power and mechanical power can be delivered to the combustion means 5 using human power and mechanical power. For example, the 1st collection means 3 accumulate | stores the organic waste collected from the several livestock farms 2 with a truck, a dump truck, etc. in a predetermined accumulation field. Furthermore, the 1st collection | recovery means 3 performs drying etc. in order to make the organic waste accumulate | stored in the accumulation place into a state which can be used as a combustion agent. As a result, the organic waste containing livestock manure can be used as a combustion agent in the combustion means 5.

  Moreover, the 1st collection | recovery means 3 may shape an organic waste in the shape and magnitude | size which are easy to use with the combustion means 5 as needed. This shaping may be performed by the shaping means 4, and the first recovery means 3 and the shaping means 4 may not be separate devices or processes.

  In addition, the first recovery means 3 may recover organic waste containing livestock excreta from the livestock farm 2 as it is and then process it into a combustion agent. Organic waste that has been processed as an agent may be recovered.

  Anyway, the 1st collection | recovery means 3 should just collect | recover the organic waste used as the combustion agent which the combustion means 5 uses. The organic waste at the time of recovery may be in a state where it can be used immediately as a combusting agent, or may be in a state that requires a further process to become a combusting agent.

  The combustion means 5 burns the organic waste recovered by the first recovery means 3 as a combustion agent.

  At this time, the combustion means 5 uses a predetermined combustion device 6. It is necessary for the combustion means 5 to obtain an inorganic waste from which most of the organic components have been removed by completely burning the combustible agent, which is an organic waste, without producing toxic gas or scattered matter. The combustion device 6 can realize combustion for obtaining such inorganic waste.

  The combustion means 5 produces | generates the inorganic waste as an unburned residue, if the organic waste collect | recovered by the 1st collection means 3 is burned as a combustion agent using the combustion apparatus 6. FIG. Since this inorganic waste is obtained by burning organic waste containing livestock manure as a component, it contains useful components for fertilizers and water quality modifiers such as phosphorus components and potassium components. For this reason, the inorganic waste obtained by combustion can be suitably used as a fertilizer or a water quality modifier in facilities of the primary industry such as the livestock farm 2. The second recovery means 7 recovers this inorganic waste as a fertilizer or a water quality modifier. Further, the second recovery means 7 may provide the livestock farm 2 with inorganic waste as a fertilizer or a water quality modifier.

  In addition, the combustion means 5 does not perform combustion only to change the organic waste into inorganic waste that becomes a fertilizer / water quality modifier, but generates heat to be used for incineration, power generation, heat generation, etc. Burn. For example, in the livestock farm 2, air conditioning for livestock is required. Since air conditioning is operated by the amount of heat, the combustion means 5 can cover the amount of heat necessary for the air conditioning used by the livestock farm 2. On the other hand, the combustion means 5 that combusts organic waste to generate heat generates inorganic waste by combustion. This inorganic organism becomes a fertilizer or water quality modifier used in the livestock farm 2.

  The livestock farm 2 often has pastures and fields for growing plants to be fed by livestock, and requires a lot of fertilizer. Moreover, it is preferable that the water quality of the drinking water for livestock and the water sprayed on pastures and fields is safe and stable. For this reason, the livestock farm 2 often requires a water quality modifier. For this reason, the inorganic waste obtained by the combustion means 5 is provided to the livestock farm 2, so that the livestock farm 2 can utilize the inorganic waste for various purposes.

  As described above, the recycling plant 1 according to Embodiment 1 burns organic waste that is difficult to process in the livestock farm 2 in order to obtain the amount of heat required in the livestock farm 2, and inorganic waste obtained as a result of the combustion. Can be provided as a fertilizer or water quality modifier useful in the livestock farm 2. That is, the recycling plant 1 realizes complete circulation type recycling with the livestock farm 2 as a starting point and a consequent point.

  The livestock farm 2 that discharges organic waste and the livestock farm 2 provided with inorganic waste as a fertilizer or water quality modifier may be the same livestock farm or different livestock farms. Good. Of course, the livestock farm is not limited to a facility for raising livestock, and any facility that requires fertilizer and a water quality modifier while discharging organic waste may be used. For example, it may be a facility related to agriculture or fisheries.

  Since the recycling plant 1 can burn the organic waste discharged from the livestock farm 2 to generate the amount of heat required by the livestock farm 2, and can provide fertilizers and water quality modifiers needed in the livestock farm 2, It is also suitable to be installed together with the livestock farm 2. Or it is also suitable that the recycling plant 1 is installed in the place which puts together the several livestock farms 2. FIG. By installing the recycling plant 1 in the vicinity of the livestock farm 2, recycling-type recycling with the livestock farm 2 as a starting point and a consequent point is easily realized.

  Moreover, if the recycling plant 1 can collect organic waste from a plurality of livestock farms 2 and provide fertilizer / water quality modifiers to a plurality of livestock farms 2 even if it is not in the vicinity of the livestock farms 2, It may be installed at a remote location. Especially in this case, the recycling plant 1 is operated, maintained, and managed in a lump, and collection from multiple livestock farms 2 and provision to multiple livestock farms can be performed in a concentrated and distributed manner. The cost involved can be reduced. This is because the cost depends on the merit of scale. In this case, the amount of heat obtained by combustion may be utilized not in the livestock farm 2 but in ordinary households, factories, and the like.

  In addition, organic waste is collected from livestock farms, and fertilizers and water quality modifiers are provided to farmers and agricultural factories. It may be different. To the last, (1) discharge and recovery of organic waste, (2) heat generation by combustion of organic waste, and (3) use of inorganic waste obtained by combustion are used and recycled where necessary. do it.

  The combustion means 5 uses a predetermined combustion device 6 for combustion of the combustion agent.

  The combustion device 6 can combust the combustor, which is an organic waste, without generating scattered matter or toxic gas. For this reason, the produced inorganic waste has almost no organic component and is used as a high-quality fertilizer or water quality modifier.

  The combustion device 6 is a device mainly composed of a cylindrical body.

FIG. 2 is a perspective view of the combustion apparatus according to Embodiment 1 of the present invention. An outline of the combustion apparatus 6 is shown.
The combustion device 2 includes a main body cylinder 12 and a combustion cylinder 13 as large components. The main body cylinder 12 performs primary combustion, and the combustion cylinder 13 performs secondary combustion. Since the primary combustion and the secondary combustion can be performed by the integrated combustion device 6, the combustor 20 can be reliably burned. In particular, the high temperature can always be maintained because the integrated combustion device 6 can perform the primary combustion and the secondary combustion.

  The main body cylinder 12 includes an outer cylinder 10 and an inner cylinder 11, and the outer cylinder 10 and the inner cylinder 11 have a double structure that can rotate coaxially. That is, the outer cylinder 10 covers the periphery of the inner cylinder 11, and the outer cylinder 10 and the inner cylinder 11 rotate together on the same axis (of course, they may rotate individually). Due to this double structure, a gap is formed between the outer cylinder 10 and the inner cylinder 11. This gap serves as a ventilation path 14 for supplying air to the internal space of the inner cylinder 11 and the combustion cylinder 13.

  A broken line arrow in FIG. 2 indicates an air supply path. Air passing through the ventilation path 14 is taken in from an opening at the base of the outer cylinder 10.

  The outer cylinder 10 and the inner cylinder 11 have an open end that is open and a closed end that is closed. A combustion cylinder 13 is connected to the open end, and the combustion agent that has undergone primary combustion inside the inner cylinder 11 is further heated to perform secondary combustion in the internal space of the combustion cylinder 13.

  A part of the outer periphery of the inner cylinder 11 has a notch, and the ventilation path 14 feeds air into the inner cylinder 11 through the notch. In addition, since the combustion cylinder 13 is connected to the outer cylinder 10, the tip of the ventilation path 14, which is a gap generated by the double structure of the inner cylinder 11 and the outer cylinder 10, is connected to the root of the combustion cylinder 13. That is, air is sent as it is into the internal space of the combustion cylinder 13 from the open portion at the tip of the ventilation path 14.

  In this way, the air passage 14 sends air into each of the internal space of the inner cylinder 11 and the internal space of the combustion cylinder 13.

  At this time, the ventilation path 14 supplies 30% to 50% of the total amount of air that is taken in and can be supplied to the internal space of the inner cylinder 11, and burns 50% to 70% of the total amount of air. Supply to the internal space of the tube 13. As described above, since the amount of air supplied to the combustion cylinder 13 performing the secondary combustion is larger than the amount of air supplied to the inner cylinder 11 performing the primary combustion, the combustion power of the secondary combustion subsequent to the primary combustion is increased. As a result, the combustion device 6 can combust the combustor 20 while maintaining a constantly high temperature (900 ° C. or higher). That is, the internal space of the inner cylinder 11 that performs primary combustion performs combustion up to a constant temperature by supplying air that is half or less of the total supply amount. As the temperature rises and the mass of the combustion agent 20 becomes lighter as the ashing of the combustion agent 20 progresses, the combustion agent 20 and the flame rise to the combustion cylinder 13 physically located above. Since the inner space of the combustion cylinder 11 is supplied with a larger amount of air than the inner cylinder 11, the combustion agent is burned at a temperature higher than the combustion temperature in the inner cylinder 11. As a result, the combustion agent 20 is surely ashed to inorganic waste.

  Here, since the main body cylinder 12 and the combustion cylinder 13 have an upward inclination with respect to the horizontal plane, it is easy to be physically connected from the primary combustion in the inner cylinder 11 to the secondary combustion in the combustion cylinder 13. As the temperature rises, the combustion object rises upward, but since the combustion cylinder 13 exists above, the combustion agent 20 is burned to a higher temperature in the combustion cylinder 13.

  Note that the combustion agent 20 is supplied to the internal space of the inner cylinder 11 through the supply path 15.

  By using the combustion device 6 having such a structure, the combustion means 5 can surely burn the combustion agent 20 to make it ash and convert organic waste into inorganic waste. Further, in combustion, the combustion agent 20 (which is organic waste recovered by the first recovery means 3) is combusted while maintaining a high temperature of 900 ° C. or higher, so that toxic gas and scattered matter hardly occur.

  As described above, the combustion means 5 can sufficiently incinerate organic waste and obtain inorganic waste by using the predetermined combustion device 6.

  In addition, since this inorganic waste is obtained from organic waste mainly composed of livestock manure, it is an effective component for water quality modifiers that improve the quality of agricultural fertilizers such as phosphorus and potassium and the quality of drinking water for livestock. Including.

  For this reason, the inorganic waste obtained by the combustion means 5 can be recovered by the second recovery means 7 and provided to the livestock farm 2 as a fertilizer or a water quality modifier. As a result, the organic waste containing livestock manure discharged from the livestock farm 2 circulates as a fertilizer and a water quality modifier useful for the livestock farm 2. The recycling plant 1 of Embodiment 1 is

  Next, the detail of each part is demonstrated.

    (First collection means)

  The first recovery means 3 recovers organic waste containing livestock manure discharged from the livestock farm 2.

  The first recovery means 3 may recover the organic waste artificially and mechanically.

  In the former case, for example, a driver driving a truck visits the livestock farm 2 and collects organic waste discharged. At the stage of recovery by the driver, the organic waste may be in the state of livestock manure and not processed at all, and in the livestock farm 2, excess components have been removed or dried. Or a state in which shaping processing is performed. The driver collects organic waste discharged from the livestock farm 2 regardless of the discharge mode.

  Moreover, if it is the latter, the bell and conveyor provided, for example in the livestock farm 2 will collect the organic waste containing livestock manure. The belt conveyor may carry the organic waste directly to the combustion means 5 adjacent to the livestock farm 2 or to the warehouse. For example, in a warehouse, livestock manure is dried and made available for use as a combustion agent. The organic waste brought into the warehouse is artificially transported to the combustion means 5.

  Thus, the 1st collection means 3 collects, in order to use the organic waste containing the livestock manure discharged | emitted in the livestock farm 2 as a combustion agent in the combustion means 5. FIG.

  The first recovery means 3 may be provided adjacent to the combustion means 5 or may be provided separately from the combustion means 5. Moreover, the 1st collection | recovery means 3 may collect | recover organic waste not only from the livestock farm 2, but also from the facility which discharge | releases organic waste containing livestock manure, such as a factory and a meat processing factory.

  Moreover, the 1st collection | recovery means 3 may perform the process and shaping for making it easy to use an organic waste as a combustion agent together with the shaping means 4 mentioned later / separately.

    (Shaping means)

  The shaping means 4 is provided as necessary, and shapes the organic waste into a pellet shape. Here, the shaping unit 4 may be provided as a step after the first recovery unit 3 or may be provided as a step before the first recovery unit 3. Further, the shaping unit 4 may be included in the same process as the first recovery unit 3, and the combustion agent shaped into a pellet shape may be provided to the combustion unit 5.

  That is, in the process before the first recovery means 3 (in the livestock farm 2), the organic waste may be shaped into a pellet shape or other predetermined shape. In this case, the first recovery means 3 recovers the organic waste shaped into a shape such as a pellet shape and passes it directly to the combustion means 5 as a combustion agent.

  Alternatively, in the first recovery means 3, the organic waste may be shaped into a pellet shape or other predetermined shape. In this case, the organic waste having an unshaped shape is collected by the first recovery means 3, and the first recovery means 3 shapes the organic waste into a predetermined shape such as a pellet shape and burns it as a combustion agent. Pass to means 5.

  Alternatively, the organic waste may be shaped into a pellet shape or other predetermined shape in the subsequent process (that is, the shaping means 4) after the first recovery means 3. In this case, the organic waste recovered by the first recovery means 3 is delivered to the shaping means 4. The shaping means 4 shapes the organic waste into a predetermined shape such as a pellet shape and passes it to the combustion means 5 as a combustion agent.

  Here, it is preferable that the shaping means 4 shapes the organic waste into a pellet shape. The pellet shape has a small cylindrical shape. By having the cylindrical shape, combustion becomes easy, and after combustion, this pellet shape can remain as an inorganic waste.

  The shaping means 4 may shape the organic waste into a shape other than the pellet shape.

  The shaping means 4 shapes the organic waste into a predetermined shape using a press device, a mold device, or the like.

    (Combustion means)

  The combustion means 5 burns the combustion agent 20 using a predetermined combustion device 6. The combustion agent 20 is an organic waste as described above, and the organic waste is preferably shaped into a pellet shape or the like.

  FIG. 3 is a perspective view of the combustion apparatus according to Embodiment 1 of the present invention. It is shown as a perspective view so that the internal situation can be seen.

  The combustion device 6 includes a main body cylinder 29 and a combustion cylinder 35 as main elements. Each of the main body cylinder 29 and the combustion cylinder 35 performs primary combustion and secondary combustion. The combustion device 6 burns the combustion agent by primary combustion in the main body cylinder 29, and then burns the combustion agent by secondary combustion in the combustion cylinder 35.

  The combustion device 6 is open at the front and closed at the rear. The amount of heat burned in the front opening is dissipated, and the combustor and air are taken in in the closed rear.

  The main body cylinder 29 includes an outer cylinder 32 and an inner cylinder 33 that can be rotated coaxially, and has a double structure in which the outer cylinder 32 covers the periphery of the inner cylinder 33 with a certain gap. Since the main body cylinder 29 is rotatable, the inner cylinder 33 is rotated. By this rotation, the internal space of the inner cylinder 33 can also be rotated. By rotating, the combustion agent stored in the internal space of the inner cylinder 33 can rotate while burning. Therefore, air and flame can be uniformly contacted with the combustion agent, and primary combustion in the inner cylinder 33 is promoted.

  A combustion cylinder 35, which is the same cylinder, is connected to the opening of the main body cylinder 29. Since the combustion cylinder 35 is connected in a state of being connected to the outer cylinder 32, one end of the gap generated between the inner cylinder 33 and the outer cylinder 32 is connected to the internal space of the combustion cylinder 35 as it is. The combustion cylinder 35 captures the combustion agent that has finished primary combustion physically rising due to a decrease in mass and a temperature increase, and burns the combustion agent at a higher temperature.

  Here, the main body cylinder 29 and the combustion cylinder 35 have an upward inclination with respect to the horizontal plane. Here, upward refers to a state in which the opening of the combustion cylinder 35 faces upward.

  By having such an inclination, since the mass of the combustant burned at a predetermined temperature in the inner space of the inner cylinder 33 is reduced, it becomes easier to move upward. Since the combustion cylinder 35 is located above, the combustion cylinder 35 burns the moved combustor. That is, secondary combustion is performed.

  Here, a gap between the outer cylinder 32 and the inner cylinder 33 becomes a ventilation path 37. The ventilation path 37 supplies the air taken in from the air supply port 45 to the internal space of the inner cylinder 33 and the internal space of the combustion cylinder 35. Here, the supply port 45 is connected to the outside world, takes air from the outside world, and sends the air to the ventilation path 37 via the ventilation port 38. The ventilation path 37 moves the supplied air, supplies a part thereof to the internal space of the inner cylinder 33, and supplies the rest to the internal space of the combustion cylinder 35.

  The inner cylinder 33 includes a blowout port 40 on the outer periphery thereof. Since the blowing port 40 communicates with the ventilation path 37, the air passing through the ventilation path 37 leaks from the blowing port 40 and is sent into the internal space of the inner cylinder 33. That is, the ventilation path 37 supplies air to the internal space of the inner cylinder 33 through the outlet 40.

  On the other hand, the tip of the ventilation path 37 is directly connected to the combustion cylinder 35. For this reason, the ventilation path 37 supplies air to the internal space of the combustion cylinder 35 from the tip.

  The ventilation path 37 supplies 30% to 50% of the total amount of air that can be taken from the outside (that is, can be supplied to the combustion device 6) to the internal space of the inner cylinder 33. On the other hand, the ventilation path 37 supplies 50 to 70% of the total air amount to the internal space of the combustion cylinder 35. That is, the amount of air supplied to the combustion cylinder 35 is larger than the amount of air supplied to the inner cylinder 33. As a result, the amount of air supplied to the combustion cylinder 35 that performs secondary combustion that needs to be combusted at a higher temperature increases, and secondary combustion is optimally performed.

  The ratio of the supply amount to the inner cylinder 33 and the supply amount to the combustion cylinder 35 by the ventilation path 37 can be adjusted as appropriate by adjusting the position, number, opening area, shape, angle, and the like of the outlet 40. .

  For example, in the comparison of the total opening area of the outlet 40 and the total opening area where the ventilation path 37 and the combustion cylinder 35 are connected, if the latter is made larger than the former, the amount of air supplied to the internal space of the inner cylinder 33 Rather, the amount of air supplied to the internal space of the combustion cylinder 35 can be adjusted to be larger.

  Combustion device 6 is supplied with 30 to 50% of the total amount of air and is supplied with 50% to 70% of the total amount of air following the primary combustion in inner cylinder 33 physically located below and the primary combustion. In addition, the combustion agent is reliably burned by the continuity with the secondary combustion of the combustion cylinder 35 physically located above the inner cylinder 33. By this reliable combustion, the organic waste is incinerated into pure water and converted into inorganic waste.

  A supply path 46 for supplying a combustion agent is connected to the closed end of the inner cylinder 33. The supply path 46 is filled with a combustion agent having a predetermined shape such as a pellet shape, and conveys the combustion agent to the internal space of the inner cylinder 33 by the screw conveyor 47. The screw conveyor 47 has blades and rotates, so that the combustion agent caught by the blades is conveyed upward and carried into the internal space of the inner cylinder 33. The periphery of the screw conveyor 47 is covered with a pipe line 34. The pipe line 34 is connected to the main body cylinder 29, and the pipe line 34 and the main body cylinder 29 form the entire skeleton of the combustion device 6.

  In the middle of the pipe 34, the supply path 46 is connected, and the combustion agent introduced from the supply path 46 reaches the pipe 34 and is conveyed to the inner cylinder 33 by the screw conveyor 47.

  Since the screw conveyor 47 needs to rotate, the motor 48 connects the rotation shaft to the screw conveyor 47 and rotates it. Further, since the main body cylinder 29 is also preferably rotated to increase the combustion efficiency, the motor 48 rotates the main body cylinder 29 (that is, the outer cylinder 32 and the inner cylinder 33). At this time, the combustion cylinder 35 may also be rotated together. At this time, the bearing 42 receives the rotating motion of the main body cylinder 29.

  Moreover, it is preferable that the combustion apparatus 6 is fixed while being installed with a frame member. The combustion device 6 is supported by the frame member 39 and the support body 41.

    (Operation of combustion device)

  Next, the operation of the combustion apparatus will be described.

  Combustion agent is introduced into the supply path 46. The combustion agent may be charged manually or by a machine. The combustion agent is an organic waste containing livestock manure and is shaped into a predetermined shape such as a pellet shape.

  The combustion agent put into the supply path 46 is carried on the blades of the rotating screw conveyor 47. The conveyed combustion agent is carried into the inner space of the inner cylinder 33. The internal space of the inner cylinder 33 is ignited by an ignition device or the like.

  The supply port 45 is connected to the outside world, and the supply port 45 takes in air from the outside world. The taken-in air is sent to the ventilation path 37 through the ventilation opening 38. The ventilation path 37 supplies air to the internal space of the inner cylinder 33 through the outlet 40. At this time, the ventilation path 37 supplies 30% to 50% of the total air amount to the inner cylinder 33 depending on the ratio of the total opening area of the outlet 40 and the opening area where the ventilation path 37 and the combustion cylinder 35 are connected. .

  The inner cylinder 33 burns the combustion agent by the supplied combustion agent and air. By rotating the inner cylinder 33, the combustion agent can be uniformly contacted with air, and the combustion agent is reliably burned. Moreover, since it is combustion by the air with less than half of the amount of air, it burns up to a certain temperature.

  The combustion agent burned in the inner space of the inner cylinder 33 increases in temperature and lightens in mass. For this reason, it can move upward gradually.

  On the upper side, a combustion cylinder 35 is provided, and more than half of the total air amount is supplied to the combustion cylinder 35. With this larger amount of air, the combustion cylinder 35 burns the combustant at a higher temperature. This is secondary combustion. By combusting the combustion agent at a higher temperature, the combustion agent is surely incinerated, and the organic component is eliminated, thereby obtaining an inorganic waste. Here, the combustion apparatus 6 can burn the combustion agent while maintaining a temperature of 900 ° C. or higher.

  In addition, the calorie | heat amount obtained with this combustion apparatus is used for the air conditioning in the livestock farm 2, or is used for the electric power generation which manages a recycling plant. This amount of heat is also utilized without being wasted.

  Moreover, since the combustion apparatus 6 burns purely, the organic waste which had the pellet shape changes into an inorganic waste with the pellet shape. By leaving the inorganic waste in the form of a pellet, the inorganic waste can be easily recovered and used as a fertilizer or a water quality modifier.

  Note that the combustion device 6 does not necessarily have to be combusted as an inorganic waste by burning the combustion agent while leaving the shape of the combustion agent. During the combustion process, the shape of the combustion agent may be deformed or collapsed.

    (Second collection means)

  Next, the second collection means 7 will be described.

  The second recovery means 7 recovers the inorganic waste obtained by burning with the combustion means 5 as a fertilizer or a water quality modifier. The second recovery means 7 may recover the inorganic waste by human power or by machine. For example, the second recovery means 7 recovers the inorganic waste obtained in the internal space of the combustion device 6 by human power. Alternatively, the inorganic waste obtained in the internal space of the combustion device 6 is collected by a suction machine or the like, and the collected inorganic waste is transported to the livestock farm 2.

  Of course, the inorganic waste may be provided to the livestock farm 2 that discharged the organic waste, or the inorganic waste may be provided to other livestock farms or farms.

  At this time, the recovered inorganic waste is classified as a fertilizer or a water quality modifier depending on the components and applications. In particular, depending on the component, it is determined what kind of crop is superior to fertilizer or what kind of land is superior to fertilizer. By combining or rearranging the types of organic waste that is input to the combustion means 5, the components of the obtained inorganic waste are determined. For this reason, fertilizers suitable for vegetables, fertilizers suitable for fruit trees, etc. by combining the types of organic waste discharged from the livestock farm 2 (types of chicken dung, cow dung etc. and other mixtures) Inorganic wastes can be obtained for different purposes. Or you may classify | categorize into a water quality modifier rather than a fertilizer by a component.

  FIG. 4 shows an example of the components of the inorganic waste obtained by the combustion by the combustion means 5. FIG. 4 is a table showing the components of inorganic waste in Embodiment 1 of the present invention.

  The components shown in FIG. 4 indicate the results of analysis of the inorganic waste obtained by the inventor by actually burning the organic waste in the predetermined combustion device 6 in a predetermined engine. As is apparent from FIG. 4, inorganic waste is rich in phosphorus and potassium, and hardly contains other components that are considered undesirable. Phosphorus and potassium are generally known to be suitable as fertilizers for plants such as vegetables and fruit trees, and are preferably derived from natural sources rather than those produced artificially. It can be seen that the inorganic waste obtained in the recycling plant 1 of the first embodiment is naturally derived, contains abundant phosphorus and potassium, and is superior as a fertilizer. Of course, components such as phosphorus and potassium have the ability to modify water quality, and the inorganic waste obtained in the recycling plant 1 of Embodiment 1 is superior as a water quality modifier.

  In addition, the component shown by FIG. 4 is an example, The inorganic waste of a different component is also obtained with the combination of organic waste.

  The second recovery means 7 not only recovers inorganic waste, but also transports and distributes it as a fertilizer and a water quality modifier to the livestock farm 2 and farms. For example, the inorganic waste discharged from the combustion device 6 may be transported to the livestock farm 2 in the same procedure as that collected by the first collection means 3. More efficiently, when a transportation means such as a truck or a dump truck goes from the combustion device 6 to the livestock farm 2, it loads and transports the discharged inorganic waste and lowers the inorganic waste at the livestock farm 2. The transportation means may be loaded with organic waste discharged from the livestock farm 2 and transported to the combustion device 6.

  In this manner, the second recovery means 7 circulates the inorganic waste generated after obtaining the amount of heat as a useful product to the livestock farm 2 and the farm that discharged the organic waste. As a result, the unnecessary organic waste discharged by the livestock farm 2 is circulated as a useful inorganic waste at the livestock farm 2 while generating a necessary amount of heat.

  As described above, the recycling plant 1 according to Embodiment 1 can circulate unnecessary organic waste discharged from the livestock farm 2 as a fertilizer / water quality modifier useful in the livestock farm 2 while changing the amount of heat. it can. As a result, it is possible to realize a complete circulation type recycling in which the starting point and the consequent point of waste coincide. In addition, since the waste is combusted so as to be completely ashed by the specific combustion device 6 used in the combustion means 5, the amount of heat can be efficiently obtained, and fertilizer and water quality that can withstand practical use. Inorganic waste as a modifier is obtained.

  The recycling plant 1 may be grasped as a plant as equipment or a device, or may be grasped as a recycling system realized including necessary equipment.

  The recycling plant and the recycling system according to Embodiment 1 have an advantage in that the amount of heat, fertilizer, and the like can be obtained from organic waste unnecessary for the beneficiary (livestock farm). Of course, the cost advantage is higher than the disposal of organic waste for a fee. In addition, for providers (recycling plant and recycling system operators), even if organic waste is collected for a fee, there is an advantage that profits can be made by selling calorie and fertilizer. Alternatively, when organic waste is accepted free of charge or with a fee, the benefits can be returned to the beneficiary by the amount of heat or fertilizer, so that the merit between the beneficiary and oneself can be balanced.

  As a result, the recycling plant and the recycling system in the first embodiment can provide both the beneficiary and the provider with cost and profit advantages. Therefore, as a form of recycling, public recognition is also gained. Easy to fix and easy to fix.

  (Embodiment 2)

  Next, a second embodiment will be described.

  The combustion means 5 in the second embodiment uses a predetermined combustion device 60. Unlike the combustion device 6 described in the first embodiment, the combustion device 60 stores a crushing member that crushes the combustion agent in the internal space of the inner cylinder 33.

  FIG. 5 is a perspective view of the combustion apparatus according to Embodiment 2 of the present invention. FIG. 5 shows the combustion device 60 so that the inside thereof can be seen. Unlike the combustion device 6 shown in FIG. 2, the crushing member B is accommodated in the internal space of the inner cylinder 33. Note that description of the same reference numerals as those in FIG. 2 is omitted.

  Combustion agent A is supplied from the supply path 46. The combustion agent A is obtained by molding organic waste into a predetermined shape. In FIG. 5, the predetermined shape is a pellet shape. In general, the combustion apparatus 60 burns a combustion agent having a pellet shape while maintaining the pellet shape to obtain inorganic waste. However, it may be necessary to obtain finely crushed inorganic waste, or it may be necessary to increase combustion efficiency. Alternatively, the shape of the injected combustion agent may be too large.

  In such a case, it may be better to combust the combustible agent A after crushing the combustor A than to burn the combustor 60 in the form of the charged pellets. In such a case, the crushing member B crushes the combustion agent A.

  The crushing member B preferably has various shapes such as a spherical shape, an elliptical spherical shape, and a rectangular shape, and is preferably a heat-resistant material. For example, the crushing member B is a substantially spherical ceramic ball mainly composed of alumina oxide and having a particle size of 2 to 30 mm. Such a crushing member B crushes the combustion agent A by colliding with the combustion agent A in the internal space of the inner cylinder 33. The combustion agent A is crushed and finely crushed by the crushing member B. In particular, since the inner cylinder 33 can be rotated together with the outer cylinder 32, the crushing member B repeatedly collides with the combustion agent A in accordance with this rotation. By repeating this collision, the crushing member B crushes the combustion agent A finely. By combusting the combustible agent A, the surface area becomes large, and it becomes easy to burn. As a result, the combustion agent A burns more easily and a large amount of heat is obtained. Furthermore, ashing proceeds by combustion, and an inorganic waste in which organic components have almost disappeared can be obtained.

  Thus, it is also suitable for the combustion device 60 to house the crushing member B as necessary.

  (Embodiment 3)

  Next, Embodiment 3 will be described.

  In the third embodiment, a case where the recycling plant described in the first embodiment is implemented as a recycling method will be described. That is, the recycling method includes a procedure in a recycling plant or a recycling system. The combustion process includes the predetermined combustion apparatus described in the first and second embodiments.

  FIG. 6 is a flowchart illustrating the recycling method according to Embodiment 3 of the present invention.

  First, in step ST1, the first recovery process recovers organic waste discharged from the livestock farm. In the first recovery step, organic waste is recovered by combining human power, mechanical power, and the like. For example, a transportation means such as a truck or a dump truck visits a livestock farm and collects organic waste discharged from the livestock farm. Or a 1st collection | recovery process collect | recovers organic waste by the belt conveyor which connects a livestock farm and a combustion apparatus.

  Next, in step ST2, the molding process molds the collected organic waste into a predetermined shape. The predetermined shape is a pellet shape or the like. Here, the molding step is not an essential element and may be used as necessary. Moreover, a shaping | molding process may be implemented in the pre-process of a 1st collection | recovery process, and may be implemented in a post process. Alternatively, the molding process may be included in the first recovery process.

  Next, in step ST3, the combustion process uses a predetermined combustion device to burn organic waste as a combustion agent. In this combustion, the combustion process obtains heat. This amount of heat is used for air conditioning in various plants and facilities or livestock farms. That is, in the combustion process, it is possible to obtain an amount of heat used in a livestock farm using unnecessary organic waste.

  In addition, the organic waste is combusted by the combustion process and converted into inorganic waste. Since the inorganic waste is sufficiently ashed by a predetermined combustion apparatus, it contains useful components such as fertilizers and water quality modifiers such as phosphorus and potassium. Furthermore, unnecessary harmful gases and scattered matter are hardly generated in the combustion process. This is due to the combustion apparatus having the predetermined configuration described in the first and second embodiments.

  Finally, in step ST4, a 2nd collection process collect | recovers inorganic waste and conveys it to the livestock farm 2 as a fertilizer and a water quality modifier. Since this fertilizer and water quality modifier are beneficially used in the livestock farm, unnecessary organic waste discharged from the livestock farm is circulated as inorganic waste useful for the livestock farm.

  By recycling such waste, the awareness of recycling is increased, and the cost and profit are balanced for the recycling company, so that there is an advantage of entering recycling. As described above, there is an advantage that recycling is easy to be established by a recycling method that is beneficial to both the beneficiary and the provider.

  As described above, the recycling plant, the recycling system, and the recycling method described in the first to third embodiments are examples for explaining the gist of the present invention, and include modifications and modifications without departing from the gist of the present invention.
