Disclosure of Invention
Problems to be solved by the invention
In general, organic matter-containing waste recovered by a garbage collection truck and organic matter-containing waste stored in a garbage tank of a garbage disposal plant are not completely removed and remain, except for organic matter contributing to gas generation, organic matter (for example, plastics), metals, glass, and the like which do not contribute to gas generation or are difficult to contribute to gas generation. The ratio of organic matters and inorganic matters contained in the organic matter-containing waste to be collected or stored, the ratio of kitchen waste to paper, the ratio of organic matters contributing to gas generation and organic matters hardly contributing to gas generation, etc. (that is, the ratio of the respective contents to the predetermined amount of the organic matter-containing waste) are different depending on the region, season, and date.
In general, in a hydrothermal treatment apparatus, a predetermined amount of organic matter-containing waste is subjected to a hydrothermal treatment for a predetermined fixed time (predetermined time), and the hydrothermal treatment is ended immediately after the predetermined time has elapsed, and the hydrothermal treated matter is taken out from the hydrothermal treatment apparatus, regardless of the ratio of the respective contents to the organic matter-containing waste. Therefore, the properties of the extracted hydrothermal treated product are different depending on the ratio of the contents to the organic matter-containing waste. For example, a water-poor, sandy or powdery water-thermal treated product may be obtained, or a water-rich, muddy or liquid water-thermal treated product may be obtained.
On the other hand, when the microorganism-based or fungus-based gas production is performed using a hydrothermal treatment solution, for example, methane production by methane fermentation is performed, it is desirable that as much as possible of the minute organic substances contained in the hydrothermal treatment solution are contained in the hydrothermal treatment solution. Therefore, it is preferable to use a screw press under pressure when separating the hydrothermal treatment liquid from the hydrothermal treatment product as described in patent document 3. However, it is not preferable to press a low-moisture (e.g., sandy) hydrothermal treatment product by a screw press because the power consumption may be increased and a failure may be caused.
In addition, when the gas generation by microorganisms and fungi is performed using the hydrothermal treatment solution, the concentration of the fine organic matters contained in the hydrothermal treatment solution is an important factor for improving the gas generation efficiency. However, since the concentration of the organic matter is greatly different between the water-rich hydrothermal treated product and the water-poor hydrothermal treated product, it is difficult to stably produce a gas in a gas production apparatus such as a methane fermentation apparatus.
Accordingly, an object of the present invention is to provide a hydrothermal treatment system capable of stably generating a gas regardless of the ratio of each content contained in organic matter-containing waste.
Technical proposal
The hydrothermal treatment system of the present invention comprises: a hydrothermal treatment device for causing a hydrothermal reaction of the waste containing the organic matter; an adjustment tank for humidifying the hydrothermal treated matter after the hydrothermal reaction; a first transfer device for transferring the hydrothermal treatment product humidified by the adjustment tank; a pressurizing and separating device for pressurizing the hydrothermal treatment product transferred by the first transfer device to separate the hydrothermal treatment product into a hydrothermal treatment solution and a residue; a dissolving tank for storing and heating the water heat treatment liquid separated by the pressure separation device; a second transfer device for returning the solubilized water-heating liquid heated by the solubilization tank to the adjustment tank; and a gas generating device that generates a gas using the hydrothermal treatment liquid stored in the dissolution tank, wherein the second transfer device returns the hydrothermal treatment liquid to the adjustment tank when the concentration of the organic matter contained in the hydrothermal treatment liquid stored in the dissolution tank is less than a predetermined concentration, and transfers the hydrothermal treatment liquid to the gas generating device when the concentration of the organic matter is equal to or higher than the predetermined concentration, wherein the predetermined concentration is a concentration of the organic matter suitable for generating a gas by microorganisms or fungi.
Effects of the invention
According to the present invention, a gas can be stably produced regardless of the ratio of the contents contained in the organic matter-containing waste.

Detailed Description
The hydrothermal treatment system according to the present invention will be described below with reference to the drawings. The following configurations and the like are examples only, and are not intended to exclude various modifications and applications of techniques not explicitly shown. The following configurations and the like can be variously modified and implemented within a range not departing from the essential constituent elements and gist of the present invention.
Fig. 1 is a schematic view showing a hydrothermal treatment system 1 according to the present embodiment. The hydrothermal treatment system 1 is the following system: the organic matter-containing waste is subjected to a hydrothermal reaction and is solubilized by high-temperature and high-pressure steam (hereinafter referred to as "hydrothermal treatment"), and a liquid (hereinafter referred to as "hydrothermal treatment liquid") such as a solution, a mixed liquid, or a slurry separated from the organic matter-containing waste after the hydrothermal treatment (hereinafter referred to as "hydrothermal treatment product") is used to generate a gas based on microorganisms or fungi.
The hydrothermal treatment system 1 includes at least a hydrothermal treatment apparatus 10, an adjustment tank 11, a first transfer apparatus 21, a pressure separation apparatus 12, a solubilization tank 13, a second transfer apparatus 22, and a gas generation apparatus 14.
Then, all the components of the hydrothermal treatment system 1 shown in fig. 1 will be described in detail below.
The hydrothermal treatment apparatus 10 is an apparatus for performing hydrothermal treatment on waste containing organic matters. Examples of the organic matter-containing waste to be put into the hydrothermal treatment apparatus 10 include kitchen waste (household garbage), wood-based waste, livestock manure, sludge, and the like discharged from households. The organic matter-containing waste collected by the garbage collection truck and the organic matter-containing waste stored in the garbage tank of the garbage disposal plant may be put into the hydrothermal treatment apparatus 10 as they are, or may be put into the hydrothermal treatment apparatus 10 after inorganic matters are removed from the organic matter-containing waste. Kitchen waste, paper, or vegetation containing an organic substance suitable for gas generation may be selectively extracted from these organic substance-containing wastes, and the extracted kitchen waste, paper, or vegetation may be fed to the hydrothermal treatment apparatus 10. The hydrothermal treatment apparatus 10 can also perform a hydrothermal treatment on a paper diaper which has caused a treatment problem in recent years in an old person facility or the like.
As will be seen later, in the hydrothermal treatment system 1, even if the ratio of the contents of the predetermined amount of organic matter-containing waste to be treated by the single hydrothermal treatment by the hydrothermal treatment apparatus 10 is greatly different for each organic matter-containing waste to be treated by the plurality of hydrothermal treatments, the gas can be stably generated by the gas generation apparatus 14 described later.
The hydrothermal treatment device 10 performs the hydrothermal treatment for a predetermined time, and the hydrothermal treatment product discharged from the hydrothermal treatment device 10 is stored in the adjustment tank 11.
The adjustment tank 11 is a device for humidifying the hydrothermal treatment product discharged from the hydrothermal treatment device 10 to adjust the properties of the hydrothermal treatment product. Here, "humidifying" the hydrothermal treatment substance includes not only the wetting of the hydrothermal treatment substance by water or liquid but also the immersing of the hydrothermal treatment substance in water or liquid.
Since the adjustment tank 11 is filled with the water-heat treatment liquid stored in the later-described solubilizing tank 13, the water-heat treatment product stored in the adjustment tank 11 is humidified. In addition to the water-heating treatment liquid being injected into the adjustment tank 11, tap water (not shown) and reuse water described below may be appropriately injected into the adjustment tank 11.
Further, a stirring device may be provided in the adjustment tank 11 to stir and mix the hydrothermal treatment product stored in the adjustment tank 11 and the injected liquid or water. When the stirring device is provided, the adjustment tank 11 can adjust the properties of the hydrothermal treatment product in a short time. For example, when the hydrothermal treatment product stored in the adjustment tank 11 is sandy, the hydrothermal treatment product can be changed into a slurry in a short time by operating the stirring device while the liquid is injected or the water is injected.
The stirring device may be any device as long as it is a device for stirring and mixing the hydrothermal treatment product stored in the adjustment tank 11 and the injected liquid or water by air stirring, mechanical stirring, or the like.
The hydrothermal treatment apparatus 10 and the adjustment tank 11 are facilities for performing a hydrothermal treatment on wastes containing organic substances, and humidifying and storing the hydrothermal treated substances obtained by the hydrothermal treatment, and are constituent elements of the first facility 2 for performing a first-stage treatment in the hydrothermal treatment system 1.
The apparatus for separating the hydrothermal treatment solution by pressurizing the hydrothermal treatment product stored in the first apparatus 2 (hereinafter referred to as "pressurizing separation") and solubilizing the hydrothermal treatment solution obtained by the pressurizing separation is the second apparatus 3 for performing the second-stage treatment in the hydrothermal treatment system 1, although this will be described later. The apparatus for generating gas using the water-heating treatment liquid solubilized by the second apparatus 3 is the third apparatus 4 for performing the third-stage treatment in the water-heating treatment system 1.
The first transfer device 21 transfers the hydrothermal treatment product humidified by the adjustment tank 11 of the first apparatus 2 to the second apparatus 3.
In the case where the first device 2 and the second device 3 are disposed close to each other, for example, in the case where the first device 2 and the second device 3 are disposed at the same or adjacent places where the distance between the first device 2 and the second device 3 is less than about 500m, it is desirable that the first transfer device 21 is a pipeline as follows: the pressure separation device 12 is connected to the adjustment tank 11 of the first equipment 2 and the second equipment 3, and includes a pulverizing pump for pressure-feeding the hydrothermally treated product whose properties have been adjusted by the adjustment tank 11 to the pressure separation device 12. In general, a pipeline is configured such that a plurality of pipes are connected to form a single path.
In this case, the hydrothermal product stored in the adjustment tank 11 of the first equipment 2 is crushed by the crushing pump through the pipeline, and is transferred to the pressure separation device 12 of the second equipment 3. When transferring the hydrothermal treated matter, the hydrothermal treated matter can be pulverized by the pulverizing pump, and thus the load of the pressure separation apparatus 12 (for example, screw press) described later can be reduced.
In the following, in the case where two devices among the first device 2, the second device 3, and the third device 4 are disposed "close to" each other, it means that the two devices are disposed at the same or different sites where the distance between the two devices is less than about 500 m.
On the other hand, in the case where the first device 2 and the second device 3 are provided remotely from each other, the first transfer device 21 is preferably an automobile (for example, a vacuum cleaner) provided with a tank or the like. For example, if the first device 2 and the second device 3 are arranged at a distance of about 500m or more from each other, they can be said to be "remote" whether they are at the same site or at different sites. In this case, the hydrothermally treated product stored in the adjustment tank 11 of the first equipment 2 is loaded in an automobile and transported to the pressure separation device 12 of the second equipment 3, and the transported hydrothermally treated product is put into the pressure separation device 12.
Here, the vehicle may be a vehicle driven by a person, or may be an automatic vehicle driven by a computer such as an artificial intelligence (Artificial Intelligence, so-called AI) which controls driving without a person.
The central control room may be provided in the hydro-thermal treatment system 1, and the driving of the vehicle may be controlled while being monitored remotely by a person using the monitoring camera. In this case, if the monitoring cameras are provided to the equipment, devices, and facilities included in the hydrothermal treatment system 1, the remote monitoring thereof can be performed by the central control room, and the safety of the operation of the hydrothermal treatment system 1 can be improved.
The operation of each of the equipment, the devices, and the facilities included in the hydrothermal treatment system 1 may be controlled by the central control room, or the operation of the hydrothermal treatment system 1 may be fully automated by AI.
In the following, when two devices among the first device 2, the second device 3, and the third device 4 are installed "remotely", the two devices are installed at the same or different sites where the distance between the two devices is about 500m or more.
In the following, the "car" may be a car driven by a person or may be an automobile driven automatically. The vehicle may be a vehicle that is monitored remotely by a person to control driving.
The pressure separation device 12 of the second apparatus 3 is a device for pressurizing the hydrothermal treatment product transferred from the adjustment tank 11 of the first apparatus 2 by the first transfer device 21 to separate the hydrothermal treatment product into a hydrothermal treatment solution and a residue (a substance remaining after separation of the hydrothermal treatment solution from the hydrothermal treatment product). The hydrothermal treatment solution is also referred to as a fermentation product, and the remainder is also referred to as a fermentation product.
The pressure separation device 12 may be constituted as follows: as shown in fig. 2, a rotary drum screen 12A is disposed in the front stage, and a screw press 12B is disposed in the rear stage. The rotary drum screen 12A may be, for example, a punching sheet metal drum screen device described in registered publication No. 6384015 of the company of the environment of the triotrop chemical engineering. The screw press 12B may be, for example, a dewatering system described in fig. 13 of registered publication No. 6734496 of the company of the environment of the three-diamond chemical engineering.
In the pressure separation device 12, the water content, viscosity, and the like of the hydrothermal treatment liquid have an influence on the recovery rate of the hydrothermal treatment liquid and the removal rate of the fermentation-related substances, and thus the mesh, the aperture ratio, the pitch (distance between the screw and the discharge port), and the like are carefully set. The dewatering system described in fig. 13 of the registered japanese patent No. 6734496 is applicable to the pressure separator 12 because the mesh is changed in accordance with the change in the properties of the hydrothermally treated product. The pressure separation device 12 may increase/decrease the size of the discharge port in response to a change in the property of the hydrothermal treatment product, for example, and change the pressure in the device.
The pressure separation device 12 may be composed of a single body of only a screw press, unlike in fig. 2.
In the pressure separation device 12 of fig. 2, first, the hydrothermal process product transferred from the adjustment tank 11 of the first equipment 2 by the first transfer device 21 is put into the rotary drum screen 12A. Then, a part of the hydrothermal treatment liquid is separated from the hydrothermal treatment product by the rotary drum screen 12A. Thereafter, the hydrothermally treated matter discharged from the rotary drum screen 12A is put into the screw press 12B.
Therefore, compared with the case where the rotary drum screen 12A is not arranged in the front stage (the case where the pressure separation device 12 is a single body of only screw press), the screw press 12B in the rear stage pressurizes the reduced amount of the hydrothermal product compared with the total amount of the hydrothermal product transferred by the first transfer device 21, thereby separating the hydrothermal product into the hydrothermal solution and the remainder. Therefore, the pressure separation device 12 of fig. 2 can realize a reduction in power (saving of electric power) of the screw press 12B.
A part of the hydrothermal treatment solution separated by the rotary drum screen 12A and the hydrothermal treatment solution separated by the screw press 12B are stored in the solubilizing tank 13 of the second apparatus 3.
The solubilizing tank 13 of the second apparatus 3 is a device for storing the hydrothermal treatment solution separated by the pressure separation device 12 and heating the same to solubilize the hydrothermal treatment solution. The temperature for heating may be set to about 40℃to 60 ℃.
By solubilizing the hydrothermal treatment liquid in the solubilizing tank 13, insoluble solid matters (hereinafter referred to as "SS") Suspended in the hydrothermal treatment liquid become solid matters (hereinafter referred to as "DS") Dissolved in the hydrothermal treatment liquid. Therefore, the Total Solids (hereinafter referred to as "TS". Ts=ss+ds) contained in the aqueous treatment solution stored in the dissolution tank 13 decreases in SS. Therefore, the solubilizing tank 13 may be said to be a device for reducing the SS of the stored hydrothermal treatment solution, increasing the DS, and promoting the acid fermentation.
In general, one having a larger amount of DS of an organic substance in TS is desirable for gas generation by microorganisms and fungi. TS, SS, or DS of the water-heating treatment liquid stored in the solubilization tank 13 can be measured by a dedicated measuring apparatus (not shown).
In addition, the dissolution tank 13 may be provided with a stirring device to stir the hydrothermal treatment solution stored in the dissolution tank 13, as in the adjustment tank 11, thereby promoting dissolution of the hydrothermal treatment solution.
The second transfer device 22 is the following: when the concentration of the organic matter contained in the hydrothermal treatment liquid stored in the solubilizing tank 13 of the second equipment 3 is smaller than a predetermined concentration (for example, TS is about 10% and DS is about 6%), the hydrothermal treatment liquid is returned from the solubilizing tank 13 to the adjustment tank 11 of the first equipment 2, and when the concentration of the organic matter reaches the predetermined concentration (substantially including the predetermined concentration or higher), the predetermined concentration may be, for example, a concentration ranging from about 10% to 12% of TS and about 6% to 8% of DS, and the hydrothermal treatment liquid is transferred from the solubilizing tank 13 to the gas generating unit 14 of the third equipment 4.
The second transfer device 22 may be configured as follows: based on the measurement results of the measurement device, either one of the adjustment tank 11 and the gas generation device 14 is automatically selected as a transfer destination, and the hydrothermal process liquid stored in the solubilization tank 13 is transferred to the selected transfer destination.
The predetermined concentration is set to a concentration of an organic substance suitable for generating a gas by microorganisms or fungi in the gas generating apparatus 14 described later. In this predetermined concentration, the pH (pH value) of the hydrothermal treatment solution stored in the solubilizing tank 13 is preferably less than 7 and preferably less than 5.
Desirably, in the same manner as the first transfer device 21, when the first equipment 2 and the second equipment 3 are disposed close to each other, the second transfer device 22 is a pipeline as follows: the pump is connected to the adjustment tank 11 of the first device 2 and the solubilization tank 13 of the second device 3, and is provided to press-feed the hydrothermal treatment liquid in the solubilization tank 13 into the adjustment tank 11.
On the other hand, in the case where the first device 2 and the second device 3 are provided remotely from each other, the second transfer device 22 is preferably an automobile (for example, a vacuum cleaner) provided with a tank or the like. In this case, the hydrothermal treatment liquid is transported from the solubilizing tank 13 to the adjusting tank 11 by an automobile.
In either case, the hydrothermal treatment liquid is circulated between the first equipment 2 and the second equipment 3 by the second transfer device 22.
In addition, it is desirable that, in the case where the second apparatus 3 and the third apparatus 4 are disposed close to each other, the second transfer device 22 is a pipeline as follows: the gas generator 14 is connected to the solubilizing tank 13 of the second device 3 and the third device 4, and is provided with a pump for feeding the hydrothermal treatment liquid in the solubilizing tank 13 to the inlet of the gas generator 14.
In the case where the first device 2, the second device 3, and the third device 4 are disposed close to each other, the second transfer device 22 may be configured as follows, for example: the second facility 3 includes a switching device in the middle of a line connecting the dissolution tank 13 and the adjustment tank 11 of the first facility 2, and the other line branched from the line is connected to the switching device and the inlet of the gas generating device 14 of the third facility 4.
As described above, the second transfer device 22 can alternatively select, by the switching device, one of the line connecting the solubilization tank 13 of the second device 3 and the adjustment tank 11 of the first device 2 and the other line to transfer the hydrothermal treatment solution stored in the solubilization tank 13, depending on the concentration of the organic matter contained in the hydrothermal treatment solution stored in the solubilization tank 13 of the second device 3.
On the other hand, in the case where the second device 3 and the third device 4 are provided remotely from each other, the second transfer device 22 is preferably an automobile (for example, a vacuum cleaner) provided with a tank or the like. In this case, the hydrothermal treatment liquid is carried from the solubilizing tank 13 to the gas generator 14 by the vehicle, and is introduced into the inlet of the gas generator 14.
In the case where the first device 2 and the second device 3 are disposed close to each other and the second device 3 and the third device 4 are disposed far from each other, the second transfer device 22 may be a pipeline in transferring the hydrothermal treatment solution between the first device 2 and the second device 3, and the second transfer device 22 may be an automobile in transferring the hydrothermal treatment solution between the second device 3 and the third device 4. That is, the second transfer device 22 may have both a pipeline and an automobile.
Similarly, in the case where the first device 2 and the second device 3 are provided remote from each other and the second device 3 and the third device 4 are provided close to each other, the second transfer device 22 may be an automobile in transferring the hydrothermal treatment solution between the first device 2 and the second device 3, and the second transfer device 22 may be a pipeline in transferring the hydrothermal treatment solution between the second device 3 and the third device 4.
The second transfer device 22 returns the hydrothermal treatment liquid to the adjustment tank 11 of the first equipment 2 until the concentration of the organic matter contained in the hydrothermal treatment liquid stored in the solubilization tank 13 of the second equipment 3 becomes the above-described predetermined concentration.
Therefore, the hydrothermal product stored in the adjustment tank 11 of the first equipment 2 can be humidified, so that the transfer of the hydrothermal product by the first transfer device 21 can be easily performed, and the power of the pressure separation device 12 of the second equipment 3 can be reduced.
Further, since the water-heating liquid returned from the solubilizing tank 13 of the second device 3 to the adjustment tank 11 of the first device 2 is heated by the solubilizing tank 13, the water-heating liquid can be injected into the adjustment tank 11 in a state of the heated temperature or in a state of being slightly cooled by natural heat radiation or the like but maintained at a temperature higher than normal temperature.
In this case, the returned water-heat-treatment liquid can contribute to the adjustment of the properties of the water-heat-treatment product by promoting the solubilization or the like of at least a part of the water-heat-treatment product stored in the adjustment tank 11.
Further, in the hydrothermal treatment system 1, although the hydrothermal treatment is sequentially performed a plurality of times over time, even if the ratio of the organic matter-containing waste to be subjected to the hydrothermal treatment by the hydrothermal treatment apparatus 10 of the first device 2 is greatly different for each of the contents, the concentration of the organic matter contained in the hydrothermal treatment solution obtained by the respective hydrothermal treatments is greatly varied, and the concentration of the organic matter contained in the hydrothermal treatment solution stored in the dissolution tank 13 can be averaged by circulating the hydrothermal treatment solution between the first device 2 and the second device 3 by the above-described return.
When the concentration of the organic substance contained in the hydrothermal treatment liquid stored in the solubilizing tank 13 becomes a predetermined concentration, the hydrothermal treatment liquid having the predetermined concentration is transferred to the gas generating unit 14 by the second transfer unit 22. Therefore, the concentration of the organic matter contained in the hydrothermal treatment liquid fed to the gas generator 14 is substantially constant and the variation is small, and the hydrothermal treatment liquid contains a large amount of organic matter contributing to gas generation. Therefore, the gas generating apparatus 14 can stably generate the gas.
In a general gas generating apparatus that generates gas from a hydrothermal treatment solution by microorganisms or fungi, it is necessary to perform solubilization and acid fermentation in the apparatus.
However, in the hydrothermal treatment system 1, when the concentration of the organic matter contained in the hydrothermal treatment solution stored in the solubilization tank 13 becomes the predetermined concentration, the solubilization and acid fermentation in the solubilization tank 13 are already in a state suitable for the generation of the gas. Therefore, the gas generator 14 can omit the solubilization and acid fermentation performed by a general gas generator, and thus can generate gas at a higher speed than the general gas generator.
The gas generating device 14 of the third plant 4 is a device for generating gas by microorganisms or fungi using the hydrothermal treatment solution stored in the solubilization tank 13 of the second plant 3. The gas generator 14 may be any device that generates gas from a hydrothermal treatment solution by microorganisms or fungi, and may be a methane fermentation device that generates methane gas by methane fermentation, or a device that generates gas such as hydrogen gas. The gas generating device 14 heats the hydrothermal treatment solution to generate a gas.
In the above, at least the configuration of the hydrothermal treatment system 1 is described. However, as shown in fig. 1, the hydrothermal treatment system 1 may further include the following devices and facilities.
The waste liquid treatment device 15 is a device for purifying waste liquid (for example, digestive juice) discharged when the gas is generated in the gas generation device 14 to generate reuse water. The waste liquid treatment apparatus 15 is, for example, an apparatus for performing biological treatment, which is treatment of nitrifying and denitrifying waste liquid.
The reuse water generated by purifying the waste liquid from the gas generator 14 by the waste liquid treatment device 15 can be supplied to the adjustment tank 11 of the first equipment 2 through the supply path 19 formed by a pipeline.
Immediately after the start of the operation of the hydrothermal treatment system 1, the hydrothermal treatment liquid is not stored in the dissolution tank 13 of the second equipment 3, and therefore the hydrothermal treatment system 1 cannot return the hydrothermal treatment liquid to the adjustment tank 11, and the hydrothermal treatment product stored in the adjustment tank 11 cannot be humidified by the hydrothermal treatment liquid. In this case, therefore, the hydrothermal treatment system 1 can humidify the hydrothermal treatment product stored in the adjustment tank 11 by supplying reuse water from the waste liquid treatment device 15 to the adjustment tank 11, and the transfer of the hydrothermal treatment product by the first transfer device 21 and the operation of the pressure separation device 12 of the second facility 3 can be smoothly performed immediately after the start of the operation of the hydrothermal treatment system 1.
In the case where the above-described return is not possible, the hydrothermal treatment system 1 may be configured to humidify the hydrothermal treatment product by injecting tap water into the adjustment tank 11. However, in order to improve the cost performance of the hydrothermal treatment system 1, it is desirable to use reuse water instead of tap water.
The third transfer device 23 is a device that transfers the gas generated by the gas generating device 14 of the third facility 4 to the gas utilization facility 16 described later.
In the case where the gas generator 14 and the gas utilization facility 16 are disposed close to each other, the third transfer device 23 is desirably a pipeline as follows: is connected to the gas generator 14 and the gas utilization facility 16, and transfers the gas generated by the gas generator 14 to the gas utilization facility 16.
On the other hand, in the case where the gas generator 14 and the gas utilization facility 16 are provided remotely from each other, the third transfer device 23 is preferably an automobile (truck) having a cargo bed on which a gas storage bottle is mounted or an automobile on which a gas storage tank is mounted. In this case, the gas generated by the gas generating device 14 may be filled in a gas cylinder or a gas tank, and may be mounted on an automobile or carried to the gas utilization facility 16.
The gas utilization facility 16 is a facility that utilizes the gas generated by the gas generating device 14 of the third apparatus 4. The gas utilization facility 16 is, for example, the following power plant: the heat generated by burning the gas in the boiler generates steam, and the steam turbine is rotated by the steam, thereby generating electric power. The gas utilization facility 16 may be a power plant including a gas turbine, a gas engine, a fuel cell, or the like, a facility for generating city gas by modifying the gas, or the like.
In the case where the gas utilization facility 16 is a power plant including a gas engine, in general, a heat recovery device for exhaust gas generated by the gas engine is provided. The heat recovery device is capable of generating warm water from the exhaust gas.
When the gas utilization facility 16 is a power plant that generates power by a steam turbine and at least one of the first device 2 and the second device 3 is disposed close to the gas utilization facility 16, the first device 2 and the second device 3 that are close to each other can use high-temperature steam, that is, wastewater steam after the steam turbine of the gas utilization facility 16 is used for power generation.
For example, when the gas utilization facility 16 including a steam turbine is provided close to the first plant 2, the gas utilization facility 16 and the first plant 2 may be connected by a pipeline, and the wastewater vapor may be transferred to the hydrothermal treatment apparatus 10 of the first plant 2 via the pipeline, and used as the high-temperature and high-pressure water vapor or a part thereof used in the water heating apparatus 10.
In the case where the gas utilization facility 16 including the steam turbine is provided close to the second facility 3, the gas utilization facility 16 and the second facility 3 may be connected by a pipeline, and the wastewater vapor may be transferred to the solubilization tank 13 of the second facility 3 via the pipeline, so as to heat the hydrothermal treatment solution stored in the solubilization tank 13.
When the gas utilization facility 16 including the steam turbine is provided close to the third facility 4, the gas utilization facility 16 and the third facility 4 can be connected by a pipeline, and the waste water vapor can be transferred to the gas generator 14 of the third facility 4 via the pipeline, so that the heating of the hydrothermal treatment solution stored in the gas generator 14 can be performed.
When the gas utilization facility 16 including the gas engine is provided close to the second facility 3, the gas utilization facility 16 and the second facility 3 can be connected by a pipeline, and the warm water generated by the heat recovery device can be transferred to the solubilizing tank 13 of the second facility 3 via the pipeline, so as to heat the hydrothermal treatment solution stored in the solubilizing tank 13. The gas utilization facility 16 and the third facility 4 may be connected by a pipeline, and the warm water may be transferred to the gas generator 14 of the third facility 4 via the pipeline, so as to heat the hydrothermal treatment solution stored in the gas generator 14.
In this way, when the gas utilization facility 16 is provided with a steam turbine, the waste water vapor discharged from the steam turbine can be used as a heat source in the hydrothermal treatment system 1, and when the gas utilization facility 16 is provided with a gas engine, the hot water generated by the heat recovery device can be used as a heat source in the hydrothermal treatment system 1, so that the cost performance of the hydrothermal treatment system 1 can be further improved.
The fourth transfer device 24 is a device for transferring the residue separated by the pressure separation device 12 of the second apparatus 3 to the waste incineration facility 17 described later.
In the case where the second facility 3 and the waste incineration facility 17 are disposed close to each other, the fourth transfer device 24 is desirably a conveyor belt as follows: is connected to the discharge port of the remainder of the pressure separation apparatus 12 and the waste tank of the waste incineration facility 17, and transfers the remainder discharged from the pressure separation apparatus 12 to the waste tank.
On the other hand, in the case where the second facility 3 and the waste incineration facility 17 are provided remotely from each other, the fourth transfer device 24 is preferably an automobile such as a truck or a garbage collection truck. In this case, the residue discharged from the pressure separator 12 can be loaded or stored in a truck bed or a garbage collection vehicle, and transferred to the waste incineration facility 17.
The waste incineration facility 17 is a facility for incinerating waste by an incinerator, and can incinerate the residue discharged from the pressure separation device 12 of the second plant 3. The waste incineration facility 17 can generate high-temperature and high-pressure steam in the boiler by heat generated in the incinerator, and generate electricity by rotating the steam turbine with the high-temperature and high-pressure steam.
When at least one of the first facility 2 and the second facility 3 and the waste incineration facility 17 are disposed close to each other, the first facility 2 and the second facility 3 that are close to each other can use high-temperature steam, i.e., waste water steam, after being used for power generation in the steam turbine of the waste incineration facility 17.
For example, in the case where the waste incineration facility 17 is disposed close to the first plant 2, the waste incineration facility 17 and the first plant 2 may be connected by a pipeline, and the waste water vapor may be transferred to the hydrothermal treatment apparatus 10 of the first plant 2 via the pipeline, and used as the high-temperature and high-pressure water vapor or a part thereof used for the water supply heat treatment apparatus 10. In the case where the waste incineration facility 17 and the second facility 3 are disposed close to each other, the waste incineration facility 17 and the second facility 3 can be connected by a pipeline, and the waste water vapor can be transferred to the solubilization tank 13 of the second facility 3 via the pipeline, so as to heat the hydrothermal treatment solution stored in the solubilization tank 13.
In this way, the waste water vapor of the waste incineration facility 17 can be effectively utilized as a heat source in the hydrothermal treatment system 1, and therefore the cost performance of the hydrothermal treatment system 1 can be further improved.
The hydrothermal treatment system 1 may be a system that is not provided with all of (1) the waste liquid treatment apparatus 15, (2) the third transfer apparatus 23, the gas utilization facility 16, and (3) the fourth transfer apparatus 24, and the waste incineration facility 17, may be a system that is provided with only one or two of the three, or may be a system that is provided with all of the three.
