Description

[Technical Field]

[0001] The present invention relates to a trigeneration system that can simultaneously generate electricity, heat, fuel, carbide, and other products while saving energy in combustion and pyrolysis equipment and reducing greenhouse gas emissions. [Background technology]

[0002] In Japan, a country with few oil resources, research and development into technologies for effectively utilizing unused heat, or "waste heat," has been actively carried out since the oil shocks of the 1970s.

[0003] For example, cogeneration systems that use waste heat to generate both heat and electricity are already in practical use in large-scale combustion facilities.

[0004] However, in general waste treatment facilities, such as medium-sized incinerators with a processing capacity of less than 20 tons per day and small, decentralized incinerators with a floor area of ​​1 m2 or less, the heat capacity is small and the temperature fluctuates greatly, even when the combustion temperature is high at 800 to 1000°C, making it difficult to steadily and stably secure the amount of heat required for power generation.As a result, the economic benefit of using a cogeneration system is small, and combined heat and power generation from a cogeneration system is not carried out.

[0005] However, even with small incineration devices, efforts to reduce greenhouse gas emissions remain important, and particularly in island regions, carbon dioxide emissions from electricity, incineration, and logistics account for a large proportion of greenhouse gas emissions that need to be reduced.

[0006] For example, industrial waste generated in remote islands and island regions is transported outside the region by ship and vehicle for disposal, which means that disposal costs are heavier than on land, directly leading to increased greenhouse gas emissions. In other words, remote islands and island regions have a social structure that makes it difficult to advance decarbonization.

[0007] In light of these circumstances, one of the inventors invented the micro-cogeneration power generation device disclosed in Patent Document 1 and the regenerative exhaust heat recovery device and combustion device and cogeneration system using the same disclosed in Patent Document 2, with the aim of commercializing and implementing small-scale cogeneration systems (so-called "micro-cogeneration").

[0008] For example, in dry distillation pyrolysis devices that heat waste plastics and rubbers at high temperatures under low-oxygen conditions to produce recycled fuel (fuel oil) and carbon materials, the recycled fuel obtained becomes a "secondary energy" that requires energy consumption such as kerosene during the manufacturing process, so energy conservation and decarbonization perspectives are essential.

[0020] FIG. 1 is a schematic diagram showing an embodiment of a trigeneration system according to the present invention. The trigeneration system is composed of three devices: a micro-cogeneration power generation unit 1 that supplies electricity by rotating a turbine using two types of working fluids with different superheat temperatures; a combustion unit 2 that uses general waste, waste materials, or solid combustion materials as a heat source to heat the liquid working fluid before it changes phase to the two types of working fluids; and a pyrolysis unit 3 that can heat or steam-bake organic materials such as rubber, plastic, and biomass in an oxygen-free state to extract or produce fuel and charcoal. The trigeneration system may also include an ash heater 4 in addition to the three devices, the micro-cogeneration power generation device 1, the combustion device 2, and the pyrolysis device 3. The ash heater 4 re-burns the ash discharged from the combustion device 2 so that the waste heat can be utilized in the thermal decomposition device 3. Furthermore, the trigeneration system may include a dry distillation gas inlet pipe 7 in the thermal cracking device 3 . The dry distillation gas introduction pipe 7 is a pipe that connects the thermal decomposition apparatus 3 and the combustion apparatus 2, and the dry distillation gas 7a generated in the thermal decomposition apparatus 3 is introduced into the combustion apparatus 2 through this pipe, so that the dry distillation gas 7a can be burned in the combustion apparatus 2.

[0021] FIG. 2 is a schematic diagram showing an embodiment of the micro-cogeneration power generation device 1. As shown in FIG. The micro-cogeneration power generation device 1 is a device that obtains turbine rotational power (power generation amount) using two types of working media (working media A 6a, working media B 6b) that have different superheat temperatures. The micro cogeneration power generation device 1 is configured such that multiple A turbines 1a, which obtain rotational power from A working medium 6a, and B turbines 1b, which obtain rotational power from B working medium 6b, are connected to both ends of a single rotating shaft. Furthermore, the A turbine 1a and the B turbine 1b are arranged on both ends of the rotary shaft, separated by a partition wall provided on the rotary shaft at a position midway between the A turbine 1a and the B turbine 1b.

[0022] A generator 1d is installed at the end of the rotating shaft on the side where turbine A 1a is connected, and a motor 1e is installed at the end of the rotating shaft on the side where turbine B 1b is connected, allowing the turbine's rotational power to be flexibly controlled in response to fluctuations in thermal or electrical load. The turbine to which the generator 1d and the motor 1e are connected may have a configuration opposite to that of this embodiment. The micro cogeneration power generation system 1 can generate turbine rotational power using two working media: A working medium 6a heated (or superheated) in A superheater 5a by exhaust gas 2h from the combustion device 2, and B working medium 6b heated (or superheated) in B superheater 5b by exhaust gas 3h from the thermal decomposition device 3.

[0023] The condenser 1c is connected to each of the A turbine 1a and the B turbine 1b, and condenses the A working medium 6a that has passed through the A turbine 1a and the B working medium 6b that has passed through the B turbine 1b, converting the vapor working medium into a liquid working medium. The liquid working medium after the phase change from the two types of working medium (A working medium 6a and B working medium 6b) in the condenser 1c is stored in the water storage tank 13. The liquid working medium stored in the water storage tank 13 can be used as is, or the water storage tank 13 can be connected to a hot water storage tank 2f (described later) and the working medium can be supplied into the hot water storage tank 2f.

[0024] The chimney 5c is connected to the exhaust duct 5, and discharges into the atmosphere the exhaust gas 2h from the combustion device 2 that has passed through the superheater 5a and the exhaust gas 3h from the thermal decomposition device 3 that has passed through the superheater 5b.

[0025] FIG. 3 is a schematic diagram showing an embodiment of the combustion device 2. As shown in FIG. The combustion device 2 is a device that uses general waste, waste materials, or solid combustion materials as a heat source to heat (or superheat) a liquid working medium before it changes phase into two types of working medium (working medium A 6a and working medium B 6b). The combustion device 2 combusts the combustion material supplied into the combustion device 2 through a combustion material inlet 2a in a primary combustion chamber 2c, and re-burns the generated combustion gas 2j in a secondary combustion chamber 2d.

[0026] When the trigeneration system of the present invention includes a dry distillation gas inlet pipe 7, the dry distillation gas 7a generated in the pyrolysis device 3 and introduced from the dry distillation gas inlet pipe 7 during combustion in the primary combustion chamber 2c is utilized or subjected to thermal decomposition treatment.

[0027] The combustion device 2 also includes a hot water tank 2f for heat exchange between the liquid working medium and the combustion gas 2j. The hot water tank 2f is disposed above or in parallel with the secondary combustion chamber 2d, and stores a liquid working medium. The liquid working medium is heated in the hot water storage tank 2f by waste heat generated in the secondary combustion chamber 2d, where gas convection and radiant heat coexist, and boils to become a wet vapor working medium. This wet steam working medium passes through a pipe 6 and passes through the A superheater 5a and the B superheater 5b. At this time, the valve 6d is open and the valve 6e is closed.

[0028] The A superheater 5a is heated by combustion gas 2h, and the B superheater 5b is heated by exhaust gas 3h from the thermal decomposition device 3, which will be described later. Therefore, the wet steam working medium is superheated to above its saturation temperature by the A superheater 5a and the B superheater 5b, which have different heating temperatures, and becomes two types of working medium (A working medium 6a, B working medium 6b) with different superheating temperatures. The two types of working media (A working media 6a, B working media 6b) have different superheat temperatures, and this superheat temperature difference can be used to rotate the turbine.

[0029] In this embodiment, two types of working media (working media A 6a, working media B 6b) with different superheating temperatures are produced from wet steam generated by heating the liquid working media stored in the hot water storage tank 2f, and trigeneration is realized by a single path in which the working media changes from liquid to vapor and then from vapor to liquid, circulating between the combustion device 2 and the micro-cogeneration power generation device 1. In another embodiment, the path through which the working medium circulates can be divided into two paths: between the combustion device 2 and the micro-cogeneration power generation device 1, and between the thermal decomposition device 3 and the micro-cogeneration power generation device 1, so that two types of working medium with different superheat temperatures circulate separately through the two paths. For example, trigeneration can be achieved even in an embodiment in which the working medium circulating through the path between the combustion device 2 and the micro-cogeneration power generation device 1 is only the A working medium 6a, and the working medium circulating through the path between the thermal decomposition device 3 and the micro-cogeneration power generation device 1 is only the C working medium 6c.

[0030] The A working medium 6a circulating through the path between the combustion device 2 and the micro-cogeneration power generation device 1 circulates, for example, as follows. When the liquid A working medium 6a stored in the hot water tank 2f is heated in the hot water tank 2f by the waste heat generated in the secondary combustion chamber 2d, it boils and becomes wet vapor A working medium 6a. This wet steam A working medium 6a passes through the pipe 6 and the A superheater 5a. At this time, the valve 6d is closed and the valve 6e is open. The A superheater 5 a is heated by the combustion gas 2 h from the combustion device 2 . Therefore, the wet steam A working medium 6a is superheated by the A superheater 5a to above its saturation temperature, passes through the A turbine 1a, becomes a liquid A working medium 6a in the condenser 1c, and is stored in the water tank 13.

[0031] The C working medium 6c circulating through the path between the thermal decomposition device 3 and the micro-cogeneration power generation device 1 is circulated, for example, as follows. When the liquid C working medium 6c stored in the working medium container 3q is heated in the working medium container 3q by the heat of the heating furnace 3a, it boils and becomes the wet vapor C working medium 6c. This wet steam C working medium 6c passes through the pipe 6 and the B superheater 5b. At this time, the valve 6d is closed and the valve 6e is open. The B superheater 5b is heated by the exhaust gas 3h from the thermal cracking device 3. Therefore, the wet steam C working medium 6c is superheated to above its saturation temperature by the B superheater 5b, passes through the B turbine 1b, becomes a liquid C working medium 6c in the condenser 1c, and is stored in the water tank 13.

[0032] As in this embodiment, the two types of working fluids are divided into working fluid A 6a that circulates through the path between the combustion device 2 and the micro-cogeneration power generation device 1, and working fluid C 6c that circulates through the path between the thermal decomposition device 3 and the micro-cogeneration power generation device 1, and circulating through each path separately can be achieved by closing valve 6d on the circulating path and opening valve 6e. On the other hand, in order to circulate two types of working media, working medium A 6a and working medium B 6b, together through the paths of the combustion device 2 and the micro-cogeneration power generation device 1, valve 6d on the circulation path is opened and valve 6e is closed. Unless otherwise specified, the following description will be based on an embodiment in which two types of working media, working media A 6a and working media B 6b, are circulated together within the paths of the combustion device 2 and the micro-cogeneration power generation device 1. Therefore, the valve 6d on the circulation path is open and the valve 6e is closed.

[0033] The combustion device 2 discharges ash 4a generated in the primary combustion chamber 2c to the outside of the combustion device 2 via a grate 2b (conveyor). At this time, waste heat and exhaust gas 4c generated from ash 4a are supplied to the thermal decomposition device 3 through an exhaust duct 5.

[0034] FIG. 4 is a schematic diagram showing an example of the ash heater 4. As shown in FIG. The ash heater 4 is a device for reburning the ash 4 a discharged from the combustion device 2 and utilizing the waste heat of the ash 4 a in the thermal decomposition device 3 . Ash 4a discharged from the primary combustion chamber 2c of the combustion device 2 is collected in the ash collector 4d of the ash heater 4 via the grate 2b. The ash 4a discharged from the primary combustion chamber 2c of the combustion device 2 contains ash that has not been completely burned, that is, unburned ash. The ash heater 4 supplies air or oxygen 4b to the ash 4a, which contains the unburned ash and is discharged from the primary combustion chamber 2c, thereby completely combusting the unburned ash. The waste heat and exhaust gas 4c generated during this process are supplied to the thermal decomposition device 3 through an exhaust duct 5, and the waste heat is circulated and utilized. Furthermore, by providing an opening / closing port on the lower side (bottom surface) of the ash collector 4d, the completely combusted ash 4a can be discharged outside the ash heater, allowing the combustion device 2 and the entire trigeneration system to operate continuously.

[0035] The ash heater 4 may also be provided with a water electrolysis device 10 as a device for supplying air or oxygen 4b. The water electrolyzer 10 is connected to an oxygen cylinder 11 and a hydrogen cylinder 12, and the oxygen cylinder 11 is filled with oxygen gas 10a generated in the water electrolyzer 10, and the hydrogen cylinder 12 stores hydrogen gas 10b generated in the water electrolyzer 10. By supplying oxygen gas 10a in oxygen cylinder 11 to ash heater 4, unburned ash contained in ash 4a discharged from primary combustion chamber 2c can be completely burned. Moreover, the oxygen cylinder 11 can be filled with air instead of the oxygen gas 10a, and the oxygen gas 10a supplied to the ash heater 4 can be replaced with air.

[0036] The hydrogen gas 10b in the hydrogen cylinder 12 can be used as a reducing gas 3j in a dry distillation type thermal decomposition apparatus, which is an embodiment of the thermal decomposition apparatus 3. The hydrogen gas 10b, which is the reducing gas 3j, is supplied to the thermal decomposition device 3 through a reducing gas introduction pipe 3k connected to the thermal decomposition device 3.

[0037] FIG. 5 is a schematic diagram showing an example of the thermal decomposition device 3. As shown in FIG. The pyrolysis device 3 is a device that heats or steams raw materials such as organic matter (rubber, plastic, biomass, etc.) in an oxygen-free state using heat from a heating furnace 3a, and extracts or produces fuel and charcoal. The thermal decomposition apparatus 3 in Figure 5 shows an example of a dry distillation type thermal decomposition apparatus, in which exhaust gas 4c flowing from the combustion apparatus 2 or the ash heater 4 is blown into the heating furnace 3a by a fan 5f, thereby increasing the temperature inside the heating furnace 3a. If the heating temperature by the exhaust gas 4c is low, the burner 3b is used to heat the material, thereby increasing the temperature inside the heating furnace 3a.

[0038] When raw material A0 such as organic matter (rubber, plastic, biomass, etc.) is placed in reactor 3c, the heat from heating furnace 3a heats or steams raw material A0 in an oxygen-free state, and product gas 3d is generated from reactor 3c. The product gas 3d is sent into a cooler 3e and cooled by a heat exchanger 3f. This allows the fuel A1 to be extracted from the raw material A0. Furthermore, since carbides remain in the reactor 3c, carbides are also produced from the raw material A0. This allows carbide and fuel A1 to be produced from raw material A0.

[0039] A reducing agent or a reducing gas 3j (hydrogen gas 10b) from a hydrogen cylinder 12 can be introduced into the heating furnace 3a or the reactor 3c. When the reducing gas 3j (hydrogen gas 10b) is introduced into the heating furnace 3a, it serves to increase the heating temperature, and when it is introduced into the reactor 3c, the oxides produced in the reactor 3c are reduced by the reducing gas 3j, producing new products. In addition, the product gas 3d generated in the reactor 3c can be introduced, in whole or in part, into the primary combustion chamber 2c of the combustion device 2. By using this generated gas 3d for combustion in the primary combustion chamber 2c, the amount of fossil fuel used in the combustion device 2 can be reduced. Even if the product gas 3d generated in the reactor 3c is a non-flammable gas (e.g., harmful substances such as dioxins and organic compounds), it can be thermally decomposed in the primary combustion chamber 2c of the combustion device 2.

[0040] FIG. 6 is a schematic diagram showing an example in which a distillation / steam distillation device is used as an example of the thermal decomposition device 3. When a raw material A0 such as a distillate or a steam distillation raw material plant is placed in the reactor 3c, the raw material A0 boils due to the heat of the heating furnace 3a, and a product gas 3d is evaporated from the reactor 3c. The produced gas 3d is cooled while being sent into the cooler 3e, and becomes a condensed liquid 3m. This allows products A1 such as distillation concentrate, essential oil, and aromatic distilled water to be collected from the raw material A0 into the collection container 3n. Furthermore, since solid matter and water remain in the reactor 3c after the volatile components have been removed, it is possible to obtain perfume raw materials, fertilizers, etc. from the raw material A0.

[0041] The embodiment shown in this figure realizes trigeneration by creating two types of working media (working media A 6a, working media B 6b) with different superheating temperatures from the wet steam generated by heating the liquid working media stored in the hot water storage tank 2f, and circulating the working media between the combustion device 2 and the micro-cogeneration power generation device 1 while changing from liquid to vapor and then from vapor to liquid through a single path.

[0042] In contrast, FIG. 7 shows an embodiment in which a circulation path for the C working medium 6c is added to the embodiment of the thermal decomposition apparatus 3 in FIG. 6. The path through which the working medium circulates is divided into two paths, one between the combustion apparatus 2 and the micro-cogeneration power generation apparatus 1 and the other between the thermal decomposition apparatus 3 and the micro-cogeneration power generation apparatus 1, and two types of working medium with different superheat temperatures circulate separately through the two paths. This is a schematic diagram showing an embodiment in which the working medium circulating through the path between the combustion apparatus 2 and the micro-cogeneration power generation apparatus 1 is only the A working medium 6a, and the working medium circulating through the path between the thermal decomposition apparatus 3 and the micro-cogeneration power generation apparatus 1 is only the C working medium 6c.

[0043] FIG. 8 is a schematic diagram showing an example of the pyrolysis device 3 in which a drying device is used. When raw materials A0 (dried materials) such as food processing residues, sludge, and manure, which are high in moisture, are placed in the reactor 3c, the raw materials A0 are heated by the heat of the heating furnace 3a, and moisture and volatile components are generated from the reactor 3c as generated gas 3d. The product gas 3d is sent into a cooler 3e and cooled by a heat exchanger 3f. This allows ammonia and liquid fertilizer components to be recovered from the raw material A0, and since solid matter remains in the reactor 3c, the raw material A0 can be used as fertilizer or biomass fuel. That is, fertilizer or fuel is also produced in the pyrolysis unit 3.

[0044] The embodiment shown in this figure realizes trigeneration by creating two types of working media (working media A 6a, working media B 6b) with different superheating temperatures from the wet steam generated by heating the liquid working media stored in the hot water storage tank 2f, and circulating the working media between the combustion device 2 and the micro-cogeneration power generation device 1 while changing from liquid to vapor and then from vapor to liquid through a single path.

[0045] In contrast, FIG. 9 shows an embodiment in which a circulation path for the C working medium 6c is added to the embodiment of the thermal decomposition apparatus 3 in FIG. 8, and is a schematic diagram showing an embodiment in which the path through which the working medium circulates is divided into two, between the combustion apparatus 2 and the micro-cogeneration power generation apparatus 1 and between the thermal decomposition apparatus 3 and the micro-cogeneration power generation apparatus 1, and the working medium circulating through the path between the combustion apparatus 2 and the micro-cogeneration power generation apparatus 1 is only the A working medium 6a, and the working medium circulating through the path between the thermal decomposition apparatus 3 and the micro-cogeneration power generation apparatus 1 is only the C working medium 6c, so that two types of working medium with different superheat temperatures circulate separately through the two paths.

[0046] FIG. 10 is a schematic diagram showing an example of the pyrolysis device 3 in which a heat transfer fluid heating device is used, and in this example, a bent tube type heat exchanger 3f is used instead of the reactor 3c in FIGS. 5 to 9. A heat transfer fluid 8 (for example, heat transfer oil, water, or a reactive fluid) is circulated through the bent pipe type heat exchanger 3f. By heating the heat transfer fluid 8 in the heating furnace 3a, the heat transfer fluid 8 can be converted into high-temperature, high-pressure oil, hot water, or steam. Furthermore, by using the bent tube heat exchanger, a plurality of reactive fluids can be flowed at constant rates, and specific products can be produced efficiently. If high boiling point heat transfer oil or water is used as the heat transfer fluid 8, restrictions on hygiene are reduced and the heat transfer fluid can be used as a high temperature secondary heat transfer fluid for heating or cleaning.

[0047] The embodiment shown in this figure realizes trigeneration by creating two types of working media (working media A 6a, working media B 6b) with different superheating temperatures from the wet steam generated by heating the liquid working media stored in the hot water storage tank 2f, and circulating the working media between the combustion device 2 and the micro-cogeneration power generation device 1 while changing from liquid to vapor and then from vapor to liquid through a single path.

[0048] In contrast, FIG. 11 shows an embodiment in which a circulation path for the C working medium 6c is added to the embodiment of the thermal decomposition apparatus 3 in FIG. 10. The path through which the working medium circulates is divided into two paths, one between the combustion apparatus 2 and the micro-cogeneration power generation apparatus 1 and the other between the thermal decomposition apparatus 3 and the micro-cogeneration power generation apparatus 1, and two types of working medium with different superheat temperatures circulate separately through the two paths. This is a schematic diagram showing an embodiment in which the working medium circulating through the path between the combustion apparatus 2 and the micro-cogeneration power generation apparatus 1 is only the A working medium 6a, and the working medium circulating through the path between the thermal decomposition apparatus 3 and the micro-cogeneration power generation apparatus 1 is only the C working medium 6c.

[0049] FIG. 12 is a schematic diagram for explaining the overall flow of the trigeneration system. The combustion device 2 combusts the combustion material supplied from the combustion material inlet 2a in the primary combustion chamber 2c, and re-burns the generated combustion gas 2j in the secondary combustion chamber 2d. The liquid working medium in the hot water tank 2f for exchanging heat with the combustion gas 2j is heated in the hot water tank 2f and boils to become a wet vapor working medium. The hot water tank 2f is disposed above or in parallel with the secondary combustion chamber 2d, and stores a liquid working medium. The wet steam working medium passes through pipe 6 and passes through superheater A 5a and superheater B 5b, which have different heating temperatures, and is heated to above its saturation temperature, becoming two types of working medium (working medium A 6a and working medium B 6b) with different superheating temperatures. At this time, the valve 6d is open and the valve 6e is closed.

[0050] By controlling the opening and closing states of valves 6d and 6e, the two types of working fluids with different superheat temperatures can be divided into working fluid A 6a, which circulates through the path between the combustion device 2 and the micro-cogeneration power generation device 1, and working fluid C 6c, which circulates through the path between the thermal decomposition device 3 and the micro-cogeneration power generation device 1, as follows.

[0051] The A working medium 6a circulating through the path between the combustion device 2 and the micro-cogeneration power generation device 1 is circulated as follows. When the liquid A working medium 6a stored in the hot water tank 2f is heated in the hot water tank 2f by the waste heat generated in the secondary combustion chamber 2d, it boils and becomes wet vapor A working medium 6a. This wet steam A working medium 6a passes through the pipe 6 and the A superheater 5a. At this time, the valve 6d is closed and the valve 6e is open. The A superheater 5 a is heated by the combustion gas 2 h from the combustion device 2 . Therefore, the wet steam A working medium 6a is superheated by the A superheater 5a to above its saturation temperature, passes through the A turbine 1a, becomes a liquid A working medium 6a in the condenser 1c, and is stored in the water tank 13.

[0052] The C working medium 6c circulating through the path between the thermal decomposition device 3 and the micro-cogeneration power generation device 1 is circulated as follows. When the liquid C working medium 6c stored in the working medium container 3q is heated in the working medium container 3q by the heat of the heating furnace 3a, it boils and becomes the wet vapor C working medium 6c. This wet steam C working medium 6c passes through the pipe 6 and the B superheater 5b. At this time, the valve 6d is closed and the valve 6e is open. The B superheater 5b is heated by the exhaust gas 3h from the thermal cracking device 3. Therefore, the wet steam C working medium 6c is superheated to above its saturation temperature by the B superheater 5b, passes through the B turbine 1b, becomes a liquid C working medium 6c in the condenser 1c, and is stored in the water tank 13.

[0053] Two embodiments in which the working medium circulates through different paths have been described above. According to the present invention, by circulating the A working medium 6a circulating through each path within the A turbine 1, and the B working medium 6b or C working medium 6c within the B turbine 1b, the A turbine 1a and the B turbine 1b can be rotated by utilizing the superheat temperature difference between the two different types of working medium.

[0054] The superheat temperature can be adjusted by the combustion device 2 and the pyrolysis device 3. The micro cogeneration power generation device 1 has a generator 1d installed at one end of the rotating shaft and a motor 1e installed at the other end of the rotating shaft, allowing for flexible control of the turbine's rotational power (power generation) in response to fluctuations in thermal or electrical load. The combustion device 2 discharges ash 4a, which contains unburned material generated in the primary combustion chamber 2c, to the outside of the combustion device 2 via a grate 2b (conveyor). The ash 4a discharged from the combustion device 2 is collected in the ash collector 4d of the ash heater 4 in order to effectively utilize the heat (waste heat) of the ash 4a, and the ash 4a is completely combusted by supplying air or oxygen 4b to the ash heater 4. The waste heat and exhaust gas 4c generated during this process are supplied to the thermal decomposition device 3 through an exhaust duct 5, and the waste heat is circulated and utilized.

[0055] By providing an opening / closing port on the lower side (bottom surface) of the ash collector 4d, the completely combusted ash 4a can be discharged outside the ash heater, allowing the combustion device 2 and the entire trigeneration system to operate continuously.

[0056] The thermal decomposition device 3 is a dry distillation type thermal decomposition device, and the temperature inside the heating furnace 3a is increased by sending the exhaust gas 4c from the ash heater 4 into the heating furnace 3a while accelerating and stirring the flow rate with a fan 5f. A raw material A0 such as an organic material (rubber, plastic, biomass, etc.) is placed in the reactor 3c, and the raw material A0 is heated or steamed in an oxygen-free state to generate a product gas 3d. If the heating temperature by the exhaust gas 4c is low, the temperature is increased by heating with the burner 3b. The produced gas 3d is cooled by a heat exchanger 3f in a cooler 3e and extracted as fuel A1, and can also be used to produce carbide in a reactor 3c. A reducing agent or a reducing gas 3j (hydrogen gas 10b) from a hydrogen cylinder 12 is introduced into the heating furnace 3a or the reactor 3c, thereby obtaining a new product.

[0057] Furthermore, by introducing the combustible dry distillation gas generated in the reactor 3c into the primary combustion chamber 2c of the combustion device 2, it is possible to reduce the amount of fossil fuel used. The non-flammable dry distillation gas generated in the reactor 3c can also be thermally decomposed in the primary combustion chamber 2c.

[0058] The trigeneration system in the above embodiment can produce heat, electricity, fuel oil, or useful carbides by circulating and utilizing the waste heat from two types of heat sources (combustion device 2 and pyrolysis device 3) within the same system, which can contribute to reducing primary energy consumption (energy saving) and greenhouse gas emissions.

[0059] FIG. 13 is a graph showing the results of an experiment in which a heat exchanger 3f was attached to the position of the hot water tank 2f in the combustion device 2 and woody biomass was burned, and shows the temperature change distribution within the combustion device 2 and the amount of waste heat recovered. The vertical axis of Figure 13 represents temperature, and the horizontal axis represents elapsed time. The dashed line in the figure represents the temperature inside the primary combustion chamber 2c, the solid line represents the temperature inside the secondary combustion chamber 2d, the dotted line represents the temperature at the gas inlet (combustion gas 2j) of the heat exchanger 3f, the two-dot chain line represents the temperature at the gas outlet (exhaust gas 2h) of the heat exchanger 3f, and the one-dot chain line represents the exhaust temperature inside the chimney 5c.

[0060] The primary combustion chamber 2c and the secondary combustion chamber 2d are at 850°C or higher, and the gas outlet of the heat exchanger 3f is at about 500°C, so the combustion device 2 satisfies the performance requirements of a combustion furnace. The temperature difference between the gas inlet (dotted line) and gas outlet (chain double-dashed line) of heat exchanger 3f is about 300°C, which indicates the temperature drop due to heat recovery. The amount of waste heat recovered was approximately 89 kW.

[0061] FIG. 14 is a graph showing the results of a power generation experiment using micro-cogeneration power generation 1, showing the relationship between the mass flow rate of steam and the power output. In FIG. 14, the vertical axis indicates the amount of power generated, and the horizontal axis indicates the mass flow rate of steam. The black squares and circles in the figure indicate the results when the generator rotation speeds were 3600 rpm and 3000 rpm, respectively. The power generation increased as the steam mass flow rate increased, and a stable power generation of approximately 380 W was obtained at 3600 rpm and 270 W at 3000 rpm.

[0062] Figure 15 is a graph showing the results of an experiment to convert waste tires into oil using the pyrolysis device 3 according to the embodiment of Figure 5, and shows the temperature changes in the primary combustion chamber 2c, secondary combustion chamber 2d, and cartridge (reactor 3c). The vertical axis of Figure 17 is temperature, and the horizontal axis is heating time. In the figure, the ● symbol indicates the temperature inside the primary combustion chamber 2c (heating furnace), the ▲ symbol indicates the temperature inside the secondary combustion chamber 2d (heating furnace), and the ○ symbol indicates the temperature inside the cartridge (reactor 3c). The temperature in the primary combustion chamber 2c is 500°C at most, and the temperature in the cartridge (reactor 3c) is about 350°C. The temperature required for heating the pyrolysis device 3 is 500°C or higher, but the temperature inside the reactor 3c needs to be heated so as to be able to maintain 350°C.

[0063] Table 1 shows the results of the power generation experiment of the micro-cogeneration power generation 1, and shows the relationship between the breakdown of the A working medium 6a and the B working medium 6b and the amount of power generation for the steam flow rate (horizontal axis) shown in FIG. In one example where the power generation output is 50 to 400 W, the vapor flow rate of the A working medium 6a is 8.5 to 101 [kg / h], and the vapor flow rate of the B working medium 6b is 72 to 77 [kg / h]. That is, in the micro-cogeneration power generation device, the A working medium 6a compensates for the shortage of the B working medium 6b, thereby making it possible to maintain a steady and stable power output.

[0065] Table 2 shows the results of the experiment to turn waste tires into oil in a pyrolysis device, and shows the processing volume, fuel consumption, extracted oil and recovered product amounts in the experiment to turn waste tires into oil shown in Figure 15. The fuel is consumed by the burner 3b used to heat the reactor 3c and for the thermal decomposition of the non-flammable dry distillation gas. This system effectively utilizes the heat (waste heat) of ash 4a discharged from the combustion device 2 and collected in the ash heater 4 as a heating source for the reactor 3c. Furthermore, the combustion device 2 can also perform thermal decomposition of non-flammable dry distillation gas, which reduces the fuel used in conventional devices and reduces greenhouse gas emissions.
