[Technical field]

[0001] The present invention relates to a hydrothermal reaction semi-carbonized product manufacturing apparatus, a hydrothermal reaction semi-carbonized solid fuel manufacturing apparatus, a hydrothermal reaction semi-carbonized solid product manufacturing method and hydrothermal reaction semi-carbonized solid fuel manufacturing method, a hydrothermal reaction semi-carbonized solid, and a hydrothermal reaction semi-carbonized solid fuel. [Background technology]

[0002] Demand for biomass fuel is steadily increasing, mainly for heat use. Furthermore, with the implementation of the Feed-in Tariff (FIT) scheme for renewable energy, the introduction of large-scale biomass power generation is being considered. However, as demand increases, concerns about the supply are becoming apparent.

[0003] Various types of pellet fuels are produced using waste resources.

[0004] The calorific value of biomass fuels such as wood, palm kernel shell, and pineapple chips is higher than that of wood or agricultural residue chips.

[0005] Biomass fuels such as wood pellets, palm kernel shell pellets, and pineapple pellets, especially wood pellets which are important as a feedstock, are dependent on imports from overseas, and there are concerns about the supply.

[0006] A large number of tests have been carried out using subcritical water reaction equipment that employs subcritical water treatment technology to break down the raw materials used for treatment, i.e., organic waste, into smaller molecules. This has confirmed that this is a promising treatment method as a solid fuel pretreatment method for turning raw materials into resources for treatment. It has been confirmed that the products are liquids or solids with a moisture content of 40-80%, and that they can be discharged in a variety of forms by adjusting the temperature, pressure, and time.

[0007] Patent Document 1 states: ·Double structure Operating conditions: room temperature to 235°C, normal pressure to 3MPa, temperature and pressure rise time: 1 to 3 hours, subcritical reaction at maximum temperature and pressure time of 5 minutes or more Drying and powdering with indirect steam heating Semi-activated (the activated carbon is fully activated and active) Carbon-based porous properties It is also described that pelletization is possible.

[0008] Patent Document 2 describes a process in which organic waste is hydrolyzed while being stirred in a double-walled pressure vessel under a high temperature of 230°C and a high pressure of 3 MPa, and also pyrolyzed or carbonized for processing. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Patent No. 4789595 [Patent Document 2] WO08 / 038361 publication Summary of the Invention [Problem to be solved by the invention]

[0010] The raw materials for processing are a mixture of waste generated from various industries, and the waste materials collected and mixed by the raw material processor are diverse. These waste materials include cinders, sludge, waste oil, waste plastic, and rubber scraps.

[0011] In addition, when the type of industry from which waste is discharged is limited, waste materials include wood chips, fiber scraps, plant residues, solid waste from animals, and various animal manures.

[0012] When obtaining recycled materials from these treated raw materials as biomass raw materials, there is a need for recyclers to produce biomass raw materials of the quality desired by the recyclers.

[0013] In addition, in light of the current situation in Japan, there is a need to generate, through hydrothermal reaction processing, a biomass material that can replace the biomass material that Japan is currently dependent on importing from overseas, by generating hydrothermal reaction carbonized solids with a calorific value equal to or greater than that of biomass fuels such as wood, palm shell, and pineapple chips from garbage waste, i.e., organic waste generated domestically.

[0014] As described in the above-mentioned Patent Document 1, when a biomass raw material is produced by hydrothermal reaction using a double-structure pressure vessel, the hydrothermal reaction product is a solid, and an advantage is that a dry powder can be obtained by adjusting the temperature, pressure, and time. However, the calorific value is only close to that of the raw material, and it is necessary to mix dewatered sludge or dried sludge to obtain a recycled material, which does not meet the above-mentioned needs.

[0015] In the invention described in Patent Document 2, organic waste is hydrolyzed while being stirred under a high temperature of 230°C and a high pressure of 3 MPa in a double-walled pressure vessel, and a process is also provided for treating the waste by pyrolysis or carbonization to produce a hydrothermal reaction semi-carbonized solid. However, the advantage of the double-walled structure is not fully utilized in the production of the semi-carbonized solid.

[0016] In view of these points, the present invention aims to meet the above-mentioned needs by making it possible to produce a biomass material with a high calorific value equal to or greater than that of wood chips, preferably 1.25 times higher, when recycled from raw materials for waste treatment through hydrothermal reaction processing, and by producing a hydrothermal reaction semi-carbonized solid of equivalent quality when produced through hydrothermal reaction processing using a double-structure pressure vessel. [Means for solving the problem]

[0017] In this invention, the product produced by hydrothermal reaction treatment using a subcritical water reaction apparatus (also called a subcritical water treatment apparatus) is called a hydrothermal reaction semi-carbonized solid, and the subcritical water reaction apparatus used to produce the hydrothermal reaction semi-carbonized solid is called a hydrothermal reaction semi-carbonized solid manufacturing apparatus, hereinafter referred to as a semi-carbonized solid manufacturing apparatus.

[0018] In the present invention, the calorific value multiple is related to the calorific value, and is related to the semi-carbonization treatment temperature and treatment time, and refers to a calorific value multiplication factor of 1.0 or more (excluding 1.0) per 1, where the standard raw material is wood chips with a moisture content of 30 to 40%, and the calorific value of the wood chips is 3,300 kcal, and wood chips refer to standard wood chips with a calorific value of 3,300 kcal.

[0019] In the present invention, the term "semi-carbonized" refers to a carbonized material in which the moisture content is zero or more, and when the moisture content is zero, the material is called "carbonized."

[0020] In the present invention, the raw material to be treated refers to garbage waste mixed mainly with organic waste, or garbage waste that can be turned into organic waste.

[0021] In the present invention, the process raw material processor and the process raw material device refer to a process raw material processor, that is, a client having a process raw material processing device, and a process raw material processing device.

[0022] In the present invention, a processed raw material processor refers to a government institution, other public organization, or company that is equipped with a processed raw material processing device and processes a specific type of processed raw material, and the type of processed raw material processor is used synonymously with the type of processed raw material (the type of composition that constitutes the mixed processed raw material), and the type of processed raw material is used synonymously with the type of processed raw material processor.

[0023] In the present invention, the relationship between the calorific value multiple and the semi-carbonization temperature and semi-carbonization time means that the set calorific value multiple is related to the setting of the semi-carbonization temperature and semi-carbonization time, and the set semi-carbonization temperature and semi-carbonization time are related to the setting of the calorific value multiple.

[0024] In the present invention, based on experience, the relationship between the calorific value of wood chips and the calorific value of wood pellets is such that the calorific value of wood pellets is approximately 1.5 times the calorific value of wood chips per weight, and a comparison between wood pellets and hydrothermal reaction semi-carbonized pellets can be made in the same way as between wood chips and hydrothermal reaction semi-carbonized wood chips.

[0025] The inventors have found that, when treating the garbage waste as the processing raw material, by adjusting the semi-carbonization temperature and semi-carbonization time, it is possible to produce a hydrothermal reaction semi-carbonized solid having a calorific value equal to or greater than that of wood chips, that is, when producing a hydrothermal reaction semi-carbonized solid by hydrothermal reaction treatment of the garbage waste as the processing raw material, it is possible to set a calorific value multiplier, and by appropriately setting and treating the calorific value multiplier, it is possible to produce a hydrothermal reaction semi-carbonized solid having a calorific value equal to or greater than that of wood chips, in combination with the hydrothermal reaction treatment of the garbage waste as the processing raw material, as a substitute for wood chips. Based on this knowledge, the inventors have come to propose a hydrothermal reaction semi-carbonized solid manufacturing device.

[0026] The present invention uses a hydrothermal reaction semi-carbonized solid production apparatus, 1) Subcritical water treatment at subcritical temperature and pressure, 2) Furthermore, in relation to the calorific value multiple and the semi-carbonization temperature-semi-carbonization time, the semi-carbonization process is carried out at an adjusted semi-carbonization temperature and semi-carbonization time based on an appropriate setting of the calorific value multiple for the hydrolyzed material treated with subcritical water, thereby producing and obtaining a hydrothermal reaction semi-carbonized solid having a calorific value higher than the calorific value 1 of the wood chips.

[0027] This feature is provided by a hydrothermal reaction semi-carbonized solid production apparatus having the following configuration.

[0028] The pressure vessel of the hydrothermal reaction semi-carbonized solid production apparatus is composed of an outer cylindrical vessel and an inner cylindrical vessel, and is provided with a control device for controlling the calorific value multiplier and the semi-carbonization temperature.

[0029] The control device is provided with a control panel, on which are provided setting areas for setting items such as the type of raw material to be treated, the hydrothermal reaction temperature, the calorific value multiple, the semi-carbonization temperature, and the semi-carbonization time.

[0030] When making this setting, the setting of the calorific value multiple is related to the setting of the semi-carbonization temperature and the semi-carbonization time, and the setting of the semi-carbonization temperature or the semi-carbonization time is related to the setting of the calorific value multiple.

[0031] The type of raw material to be processed, the hydrothermal reaction temperature, the calorific value multiplier, the semi-carbonization treatment temperature, and the semi-carbonization treatment time are set so as to produce a hydrothermal reaction semi-carbonized solid with a calorific value multiplier of 1.0 or more (excluding 1.0) when the calorific value of the set wood chips is 1.0.

[0032] A hydrothermal reaction semi-charcoal solid is produced having a calorific value multiplier of 1.0 (not including 1.0) or more, preferably 1.25 or more.

[0033] A dried and semi-carbonized hydrothermal reaction solid is produced having a moisture content of 2 to 20%, preferably 3 to 6%. Effect of the Invention

[0034] According to the present invention, the above processes 1) and 2) can be carried out by hydrothermal reaction treatment using a hydrothermal reaction semi-carbonized solid production apparatus with a double-structure pressure vessel, and a hydrothermal reaction semi-carbonized solid that can meet the above-mentioned needs can be produced, which has a high calorific value that is a multiple of the calorific value of the wood chips, for example, 1.0 (excluding 1.0) times or 1.25 times or more.

[0035] From the hydrothermal reaction semi-carbonized solid, a biomass raw material with high fermentation capacity can be produced, or hydrothermal reaction semi-carbonized pellets with high calorific value can be produced. [Brief description of the drawings]

[0042] The pressure vessel 1 is provided with lids 14 and 15 for closing at both ends, and one of the lids 15 is provided with a drive motor 16 on its side. The drive motor 16 is connected to a stirrer 13 having a rotating blade.

These signal data are recorded in the recording means of the control device 5. The measured moisture amount is used to set control data for the semi-carbonization treatment time.

[0044] The pressure vessel 1 is equipped with a steam exhaust pipe 18 connected to the inner cylindrical vessel 12, and a discharge control valve 19 is provided on the steam exhaust pipe 18. With this configuration, water vapor within the inner space can be discharged to the outside. The pressure vessel 1 is provided with an input hopper 25 connected to the inner cylindrical vessel 12, and an outlet having an outlet pipe 26 connected to the inner cylindrical vessel 12. The outlet pipe 26 is provided with an outlet discharge control valve 20. With this configuration, the formed hydrothermal reaction semi-carbonized solid can be discharged to the outside.

[0045] The pulverizing means 3 receives the collected raw materials for treatment 31 and the collected medical waste 32, pulverizes the two collected wastes, and feeds the powdered waste into the feeding hopper 25. The feeding hopper 25 is provided with a control valve 38, and the feeding of the raw materials for treatment 31 is controlled by the control device 5.

[0046] The pulverization operation of the pulverization means 3 is controlled by a control device 5 connected by an electronic circuit.

[0047] The type of raw material 31 to be processed is identified at the stage of collection. In many cases, the type of raw material to be processed is identified by a raw material processor. By attaching a photographing means (not shown) near the input hopper 25, comparing the image with a reference image, and providing a means for identifying the type of raw material to be processed (not shown), the type of raw material to be processed can be identified automatically. Identification data is input to the control device 5.

[0048] The boiler 2 includes a steam supply passage 33 that supplies the generated steam to the pressure vessel 1. A superheated steam generator 40 is provided in the steam supply passage 33 to superheat the generated steam and supply it to the pressure vessel 1.

[0049] The steam supply line 33 branches into a branch line 34 for supplying superheated steam into the space between the outer cylindrical vessel 11 and the inner cylindrical vessel 12, and a branch line 35 for supplying steam into the space inside the inner cylindrical vessel 12, and each branch line is provided with control valves 36, 37. The control valves 36, 37 are connected to the control device 5, and opening and closing of the control valves 36, 37 are controlled and adjusted by the control device 5. By providing the superheated steam generator 40, the internal temperature, i.e., the hydrothermal reaction treatment temperature, can be increased regardless of the pressure inside the inner cylindrical vessel.

[0050] The hydrothermal reaction semi-carbonized solid manufacturing apparatus 100 is composed of a pressure vessel equipped with an inlet for the raw material to be processed, a mechanism for homogenizing the hydrothermal reaction, and an outlet for removing the produced hydrothermal reaction semi-carbonized solid, a heat source for the hydrothermal reaction treatment and heat treatment, and a control device for controlling the hydrothermal reaction treatment and heat treatment, and produces hydrothermal reaction semi-carbonized solid by the hydrothermal reaction treatment and heat treatment of the raw material to be processed.

[0051] The hydrothermal reaction semi-carbonized solid production apparatus 100 optionally includes a powderizing means 3 for converting the raw material to a powdered raw material.

[0052] The pressure vessel is composed of an outer cylindrical vessel and an inner cylindrical vessel, and the inner space and The inner cylindrical container defines an outer space between the inner cylindrical container and the outer cylindrical container.

[0053] The control means sets the hydrothermal reaction temperature of the subcritical reaction range of water under a predetermined pressure in the hydrolysis treatment area, and the raw material is hydrolyzed in the hydrolysis treatment area to form a hydrolyzed substance.

[0054] For example, water vapor is introduced into the inner space, and a hydrolysis treatment region is formed in which the hydrothermal reaction temperature is within the subcritical reaction range of water, that is, within 180°C and the hydrothermal reaction pressure is within 10 MPa, typically within 3 to 3.5 MPa, and the hydrothermal reaction time is controlled to be appropriately set, and the powdered processing raw material is hydrolyzed to form a powdered hydrolyzed substance.

[0055] The introduction of water vapor into the inner space is stopped, and the water vapor in the inner space is discharged to the outside.

[0056] In the drying / semi-carbonization treatment area, a semi-carbonization treatment temperature obtained from the type of raw material to be treated and the calorific value multiple is set under a specified pressure, and a dried / semi-carbonized hydrothermal reaction semi-carbonized solid is produced from the hydrolysis treatment material, which has a specified calorific value relative to the calorific value of the wood chips and has a moisture content of 2 to 20%, preferably 3 to 6%.

[0057] For example, a drying / semi-carbonization treatment area is formed in the outer space, in which the carbonization temperature is equal to or higher than the hydrothermal reaction temperature and is within a range of 230°C, and the treatment time is controlled, to produce hydrothermal reaction semi-carbonized pellets from the hydrolysis treatment material, typically a dried and semi-carbonized hydrothermal reaction semi-carbonized solid that can produce hydrothermal reaction semi-carbonized pellets with a high calorific value.

[0058] Wood chips with a moisture content of 35-40% and a calorific value of 3300 kcal / kg when carbonized are widely known. The inventors' analysis also confirmed that wood chips with a moisture content of 40% and a calorific value of 3300 kcal / kg when carbonized are used.

[0059] According to the experiments conducted by the inventors, it has been confirmed that a hydrothermal reaction semi-carbonized solid can be produced by drying and semi-carbonizing the wood chips to a moisture content of 3-6%, and the calorific value is 1.25 times or more that of 3,300 kcal / kg of wood chips with a moisture content of 35-40%.

[0060] A drying / semi-carbonization treatment area can be formed with the semi-carbonization temperature being within 230℃ and the treatment time being controlled.

[0061] When the powder particulate hydrothermal reaction semi-carbonized solid is obtained, a hydrothermal reaction semi-carbonized pellet, which is the above-mentioned hydrothermal reaction semi-carbonized solid and is in the form of an aggregate of the powder particulate hydrothermal reaction semi-carbonized solid, can be formed.

[0062] As the semi-carbonized solid matter from the hydrothermal reaction is recovered 42, harmful substances are rendered harmless and their volume is reduced 43.

[0064] The produced hydrothermal reaction torrefied solids can be used as a biomass feedstock, and the produced hydrothermal reaction torrefied pellets can be used for power generation or as a combustion fuel.

[0065] Hydrothermal reaction semi-carbonized solids or hydrothermal reaction semi-carbonized pellets, which have 1.5 times the calorific value of wood chips or wood pellets, can be used as a substitute for biomass raw materials that are currently imported from overseas. Substitute biomass raw materials can be produced by hydrothermal reaction processing using processed raw materials as the raw material.

[0066] By adjusting the hydrothermal reaction temperature, the type of raw material to be processed, and the semi-carbonization temperature, it is possible to produce hydrothermal reaction pellets with high calorific value for use as biomass raw material or fuel of the same quality at the raw material processing plant of the facility itself, at companies or public institutions, and at emission control companies.

When the displayed set value is changed or accepted as control data without being changed, the decision command 54D is operated to make a decision, and the set value displayed in the setting item is made the control value, displayed as control data, and adopted for operation. By operating the decision command 54D, the set value is confirmed as the operation value.

[0100] The semi-carbonization temperature and semi-carbonization time are related to the calorific value multiple and are determined by the value of the calorific value multiple. These are obtained in advance through experiments, and the relationship is stored as relationship data. This relationship data is used to obtain the semi-carbonization temperature and semi-carbonization time based on the calorific value multiple. The semi-carbonization temperature is set to a temperature in the low temperature range. Setting the temperature in the low temperature range is effective in obtaining the desired calorific value multiple.

[0101] This relationship data can be utilized to set the calorific value multiplier based on the semi-carbonization temperature and semi-carbonization time settings.

[0102] By providing a control panel in the control device 5, when producing a dried and semi-carbonized hydrothermal reaction semi-carbonized solid, it is possible to produce a dried and semi-carbonized hydrothermal reaction semi-carbonized solid with a moisture content of 3 to 6%, which fully reflects the wishes of the client, the raw material processor.

[0103] In the other data display area 54B, measurement data, for example the moisture content (%) measured by the moisture sensor 23, various instruction data, and data of the results of calculation processing are displayed.

[0104] FIG. 3 is a data diagram showing an example of control data consisting of the relationship between the raw material to be processed, the semi-carbonization temperature, and the calorific value multiple.

[0105] The inventors have discovered that, when processing garbage waste, which is the raw material for processing, by adjusting the semi-carbonization temperature and semi-carbonization time, it is possible to produce a hydrothermal reaction semi-carbonized solid having a calorific value greater than or equal to the calorific value of wood chips; in other words, when producing a hydrothermal reaction semi-carbonized solid by hydrothermal reaction treatment of garbage waste, which is the raw material for processing, a calorific value multiplier can be set, and by appropriately setting and processing this calorific value multiplier, it is possible to produce a hydrothermal reaction semi-carbonized solid that serves as a substitute for wood chips and has a calorific value greater than or equal to the calorific value of wood chips, in combination with the hydrothermal reaction treatment of garbage waste, which is the raw material for processing.

[0106] Figure 3 shows relationship data obtained regarding the type of raw material to be processed, the semi-carbonization temperature (℃), the semi-carbonization time (min), the post-processing calorific value (kcal), the calorific value multiple, the calorific value multiple by setting, and the raw material processing company (industry), and also shows an example of the calorific value multiple by setting set based on the relationship data, i.e., the control data.

[0107] For example, in the case of 1. wood chips, the semi-carbonization temperature is 200°C, the processing time (semi-carbonization time) is 30 minutes, the post-processing calorific value is 5330 kcal, and the calorific value multiple is 1.62. The calorific value multiple of 1.62 was used as the control data. 5. In the case of cow dung, the post-treatment calorific value is 5284 kcal and the calorific value multiplier is 1.60 when the carbonization temperature is 200°C and the treatment time is 15 minutes. In this case, if the calorific value multiplier is set to 1.5 as the control data, the desired hydrothermal reaction semi-carbonized solid can be produced within 15 minutes of treatment time when the semi-carbonization temperature is set to 200°C. In this case, the treatment time can be further shortened by setting the calorific value multiplier to 1.0 (excluding 1.0) or more and 1.5 or less.

[0108] By appropriately changing the semi-carbonization temperature setting or the semi-carbonization time setting and setting the control data, a hydrothermal reaction semi-carbonized solid with a calorific value multiplier of 1.0 (excluding 1.0) or more can be generated based on the stored relationship data. When a hydrothermal reaction semi-carbonized solid with a calorific value multiplier of 1.0 (excluding 1.0) or more cannot be generated, an alarm is displayed on the alarm indicator on the control panel.

[0109] The same applies to other processing materials.

[0110] Highest demand: 9. Processing of wood chips, paper scraps, food waste, and waste plastics If the raw material processor is a local government, a carbonization temperature of 200°C, a processing time of 30 minutes, and a post-processing calorific value of 4810 kcal and a calorific value multiplier of 1.46 will be obtained. In this case, if a calorific value multiplier of 1.25 is set as the control data, the desired hydrothermal reaction semi-carbonized solid can be generated with a semi-carbonization temperature set to 200°C and a semi-carbonization time of 30 minutes or less.

[0111] 9. The mixture state of the raw materials to be processed (wood chips, paper scraps, food waste, and waste plastic) varies greatly depending on the season, but if the calorific value multiple is set to 1.25, and the semi-carbonization temperature is set to 200°C, the desired hydrothermal reaction semi-carbonized solids can be produced within 30 minutes of processing. For 4. Textiles, 9. Wood chips, paper scraps, food waste, waste plastic, 11. Young scallops, sawdust, and 13. Waste mushroom beds, the calorific value multiple is set according to the calorific value multiple, but even in these cases it can be set to a value greater than or equal to 1.0 (excluding 1.0) and less than the calorific value multiple.

[0112] There was not enough data available for 7. Pig manure, 12. Scallops, sawdust, rice husks, and 14. Vegetable waste. When processing these raw materials, they will be mixed with other raw materials with high calorific value. In addition, data will be supplemented by additional experiments.

[0113] Regarding the limited processing time associated with the semi-carbonization temperature (℃), the semi-carbonization process is 20 to 60 minutes, which is appropriately selected and adopted according to the intentions of the processing raw material, i.e., the processing raw material processor.

[0114] FIG. 4 is a diagram showing the relationship between the semi-carbonization treatment temperature and the calorific value in the semi-carbonization calorific value peak zone for wood chips, on the XY coordinate system.

[0115] When the semi-carbonization temperature was room temperature, 25°C, the calorific value was 3300 kcal and the calorific value was 1.0. Above room temperature, the calorific value is 1.0 (excluding 1.0) at the semi-carbonization temperature. When the semi-carbonization temperature was 200°C, the calorific value was 5330 kcal and the calorific value was 1.62. As shown in the figure, the semi-carbonization calorific value peak zone can be set. For raw materials that will be processed into wood chips, the semi-carbonization calorific value peak zone can be set to a semi-carbonization temperature (°C) of 180 to 230. Processing in this zone can provide a maximum calorific value of 5330 kcal and a calorific value of 1.5 or more.

[0116] For other raw materials to be processed, similar semi-carbonized calorific value peak zones may be set.

[0117] The set relationship data shown in FIG. 3 and FIG. 4 is acquired, and control data is set for all or a part of the set data.

[0118] The control device acquires relevant data regarding the type of raw material being processed, the semi-carbonization temperature (℃), the processing time (min), the post-processing calorific value (kcal), the calorific value multiple, and the processing industry, and the control data set based on the relevant data is stored in advance.

[0119] In Fig. 3, the relevant data regarding the type of raw material to be processed, the semi-carbonization temperature (℃), the processing time (min), the post-processing calorific value (kcal), and the processing industry were acquired in advance by the manufacturer of the hydrothermal reaction semi-carbonized solid production apparatus 100. Based on this relevant data, control data representing the relationship between the raw material to be processed, the semi-carbonization temperature, and the calorific value multiple was generated, and was stored and saved in the storage means of the control device.

[0120] As the processing time of the raw material processing by the processor progresses, relevant data regarding the type of raw material processed, the semi-carbonization processing temperature (℃), the processing time (min), the post-processing calorific value (kcal) and the processing industry are accurately obtained, and the data is obtained by the manufacturer of the hydrothermal reaction semi-carbonized solid production equipment 100, and more accurate control data is generated and stored.

[0121] In Figure 3, the reference raw material when obtaining the heat generation multiple was wood chips with a moisture content of 30-40% and 3300 kcal. Cedar chips were used as an example.

[0122] In the case of a processing material having a heat generation multiplier exceeding 1.5, the heat generation multiplier of 1.5 is adopted as the control data, and in the case of a processing material having a heat generation multiplier exceeding 1.0 to 1.5, the obtained heat generation multiplier is adopted as the heat generation multiplier.

[0123] As shown in FIG. 3, for many processing raw materials, a heat generation multiple of 1.0 (excluding 1.0), 1.25 or 1.5 is adopted as control data.

[0124] FIG. 5 is a functional diagram showing the configuration of a hydrothermal reaction semi-carbonized solid production apparatus.

[0125] The raw material to be treated is fed into a pressure vessel 61, and a subcritical water reaction process 63 is carried out at a temperature of, for example, 180°C in a hydrolysis process 62, and a low-temperature semi-carbonization process 65 is carried out in a drying and semi-carbonization process 64. At this time, the heat generation factor, semi-carbonization temperature, and / or semi-carbonization time are adjusted 66 so that a hydrothermal reaction semi-carbonized solid having, for example, 1.25 times or more combustion energy compared to wood chips is formed at a temperature of 230°C or less.

[0126] Hydrothermally torrefied solids are formed and collected 67, and the hydrothermally torrefied solids are collected to produce hydrothermally torrefied pellets 68 or to produce bio-fermentation feedstock 69.

[0127] FIG. 6 is a diagram showing the relationship between the semi-carbonization treatment temperature and the calorific value in the semi-carbonization calorific value peak zone for wood chips, on the XY coordinate system.

[0128] In Figure 6, the X-axis represents the semi-carbonization temperature (℃) in the semi-carbonization heat value peak zone, the Y-axis represents the heat value (kcal / kg), and an example of the relationship between the semi-carbonization temperature (℃) and the heat value (kcal / kg) is plotted on the coordinates. The semi-carbonization time was 30 minutes.

[0129] The semi-carbonization temperature in the semi-carbonization heat generation peak zone is obtained so that a temperature in the low temperature range is set, and then the semi-carbonization temperature is obtained by varying the semi-carbonization time.

[0130] Wood chips exhibit a high calorific value (kcal / kg) when the semi-carbonization temperature is around 200°C, and preferably have a high probability of obtaining a calorific value multiple of 1.5 or more in the semi-carbonization calorific value peak zone of 180-230°C. The semi-carbonization temperature is adjusted to 180°C, 200°C or 230°C, or within these temperature ranges, and the treatment time is adjusted to 20-60 minutes, for example, so that the moisture content is 2-20%, preferably 3-6% or less.

[0131] Through this adjustment, it is possible to produce from the processed raw material hydrothermal reaction pellets with a high calorific value equivalent to that of wood pellets, or biomass raw materials or high calorific value, and by adjusting the moisture content to 3-6% or less, it is possible to obtain drier wood pellets.

[0132] FIG. 7 is a diagram showing the configuration of an apparatus for producing semi-carbonized solid material by hydrothermal reaction according to another embodiment of the present invention.

[0133] The configuration of the hydrothermal reaction semi-carbonized solid production apparatus 100 is substantially the same as the configuration of the hydrothermal reaction semi-carbonized solid production apparatus shown in FIG.

[0134] 7, a heater 17 is provided in the external space 7, and a heating power source 2A is provided in parallel with the boiler 2. The heating power source 2A is connected to the control device 5 by an electric circuit and is controlled to be turned on and off.

[0135] The heater 17 is electrically heated by the supply of electricity from a heating power source 2A.

[0136] 1 in that the outer space 7 is heated by a heater 17 instead of by steam heat. However, the hydrothermal reaction torrefied solid material is the same in that a dried and torrefied hydrothermal reaction torrefied solid material capable of producing hydrothermal reaction torrefied pellets, typically high calorific value torrefied pellets, is produced from a hydrolysis treatment substance.

[0137] This is the same as in the previous example, in which steam is introduced into the inner space, a low-temperature hydrolysis treatment area is formed in which the hydrothermal reaction temperature is within the subcritical reaction range of water, 230°C or less, and the hydrothermal reaction pressure is within 10 MPa, typically 3.5 MPa, and the hydrothermal reaction time is controlled to an appropriately set time, and the powdered processing raw material is hydrolyzed to form a powdered hydrolyzed material, but what is different is that a low-temperature drying / semi-carbonization treatment area is formed in the outer space by heater 17, where the carbonization temperature is above the hydrothermal reaction temperature and within 230°C, and the treatment time is controlled.

[0138] FIG. 8 is a diagram showing a method for producing semi-carbonized solid material by hydrothermal reaction according to an embodiment of the present invention.

[0139] In FIG. 8, the hydrothermal reaction semi-carbonized solid production method includes: Input of processing materials (S1) Subcritical reaction processing (under subcritical reaction pressure, e.g. within 230℃) Formation of hydrolysis treatment area (S2) (Hydrolysis step: for example, 10 to 60 minutes) Formation of hydrolyzed substances Stop steam input, exhaust steam (S3) (Degassing process: for example, 10 to 15 minutes) Hydrothermal reaction: Generation of semi-carbonized solids (S4) (Semi-carbonization process: for example, 20 to 60 minutes) Formation of dry, low-temperature semi-carbonized area Low-temperature semi-carbonization (for example, within 230℃) The wood chips are dried and semi-carbonized to a moisture content of 2-6%, and have a calorific value 1.5 times or more higher than that of the wood chips (3300 kcal / kg in this embodiment). Production of semi-carbonized pellets by hydrothermal reaction (S5) The hydrothermal reaction semi-carbonized solid is a hydrothermal reaction semi-carbonized pellet in the form of an aggregate of powder-like hydrothermal reaction semi-carbonized solid.

[0140] Production of biomass fermentation feedstock that becomes powder-like particulate semi-carbonized solids through hydrothermal reaction (S6) According to experiments by the inventors, the hydrolysis treatment area is adjusted by the control means under a predetermined pressure to a temperature within 230°C of the hydrothermal reaction temperature of the subcritical reaction range of water, the raw material to be treated is hydrolyzed to form a hydrolysis treatment substance (hydrolysis process: 30 minutes), the introduction of steam into the inner space is stopped and the steam in the inner space is discharged to the outside (degassing process: 10 minutes), and the low-temperature drying / semi-carbonization treatment area is operated under a predetermined pressure at a low temperature within 230°C of the hydrothermal reaction temperature, and a dried / semi-carbonized hydrothermal reaction semi-carbonized solid with a calorific value of 5270 kcal / kg is produced, which is 1.65 times the calorific value of 3300 kcal / kg of wood chips with a moisture content of 30 to 40% (semi-carbonization treatment process: 40 minutes).

[0141] According to this embodiment, the above-mentioned processes 1) and 2) can be carried out by hydrothermal reaction treatment using a double-structure pressure vessel, and a set-specific heat generation multiplier is used, and a heat generation multiplier of 1.0 or more (excluding 1.0) relative to the heat generation of wood chips with a moisture content of 30 to 40% can be produced. For example, when processing raw materials collected by a local government using the processing equipment, or by specifying the type of raw material to be processed, a hydrothermal reaction semi-carbonized solid can be produced that can meet the above-mentioned needs, or a biomass raw material with high fermentation capacity can be produced using the hydrothermal reaction semi-carbonized solid as a raw material.

[0142] Furthermore, from the hydrothermal reaction semi-carbonized solid, it is possible to produce hydrothermal reaction semi-carbonized pellets having a high calorific value compared to the high calorific value of wood pellets.

[0143] FIG. 9 shows photographs of the raw material for the hydrothermal reaction and the semi-carbonized solid product after the hydrothermal reaction, drying, and semi-carbonization.

[0144] Figure 9(1) is a photograph of the raw material being treated for the hydrothermal reaction, and Figure 9(2) is a photograph of the hydrothermal reaction semi-carbonized solid after hydrothermal reaction, drying, and semi-carbonization.

[0145] A semi-carbonized solid was produced by hydrothermal reaction, and a photograph of the raw material for hydrothermal reaction shown in Figure 9(1) was obtained. The semi-carbonized solid was obtained by drying and semi-carbonizing to a moisture content of 3-6%, and had a heat generation factor of 1.5 times (excluding 1.5) or more compared to the heat generation of the wood chips.

[0146] The hydrothermal reaction semi-carbonized solid is formed into powder particles and aggregated to produce hydrothermal reaction semi-carbonized pellets with a higher heat value than wood pellets formed from wood chips with a moisture content of 35 to 40%. A photograph of the hydrothermal reaction semi-carbonized solid after hydrothermal reaction, drying and semi-carbonization, shown in Figure 9 (2), was obtained. [Explanation of symbols]
