Description

  The present invention relates to a resource circulation system in which environmental conservation can be obtained by effectively using energy resources.

In recent years, global warming due to carbon dioxide emissions has been a concern, and in order to reduce carbon dioxide emissions to prevent global warming, it is proposed to use plant-derived alcohol and biomass-derived alcohol as fuel oil Has been. That is, so-called bioalcohols that can be used as fuel for agricultural and forestry products such as plants and biomass that fix carbon dioxide in the atmosphere as carbon, do not increase the carbon dioxide in the air, so this bioalcohol or bioalcohol It is known to use ethyl tertiary butyl ether (ETBE) produced by using a fuel oil mixed with fuel oil.
However, the produced ETBE is mixed with ethanol as a raw material and butanol as a by-product. Moreover, since alcohol has a relatively high water absorption, there is a relatively high possibility that water will be mixed in alcohol or ETBE to be mixed as mixed fuel oil. For this reason, in the transport route of bioalcohol or ETBE, there is a possibility that inconveniences such as corrosion of piping called so-called dry corrosion and swelling of packing occur. Further, when used in an internal combustion engine such as an automobile, technical measures such as applying a configuration for preventing inconvenience such as corrosion are also necessary. As described above, since technical measures in the field of use are necessary, it is a reality that bioalcohol or ETBE is not sufficiently utilized.

On the other hand, in each municipality, local government, etc., the treatment of surplus activated sludge generated by sewage treatment and waste disposal has become a major problem. For this reason, in order to use activated sludge, raw garbage, etc. as a fuel source, granulation into a solid fuel called a so-called biochip has been carried out. Also, in each manufacturing industry, product recycling activities have been carried out due to carbon dioxide problems and resource problems.
However, biochips have a relatively small amount of heat and are insufficient to operate a turbine for power generation. In addition, it is very expensive to construct a new facility for using the biochip for power generation. For these reasons, it can be used, for example, in a heated pool in a municipality, or mixed with a coal furnace for power generation, and most are incinerated with combustible waste. Is the actual situation. Similarly, some of the resources recovered through recycling cannot be reused. For combustible materials such as rubber and plastics such as tires, some are carbonized and granulated as solid fuel. Although it is resource-recycling, equipment for resource-recovery is necessary, or the processing cost of resource-recovery is not commensurate with the cost of energy obtained from the resource-recovered fuel. In fact, solid fuel that has been turned into resources is incinerated.
Furthermore, although the incineration process reduces the volume of waste, solid fuel, and the like, incineration ash and the like are generated, so it is necessary to treat the incineration ash. For this reason, although some incineration ash is reused for building materials, etc., the amount of incineration ash to be generated is not stable, and the composition of incineration ash is derived from what is incinerated, Incineration ash that is difficult to use as building materials is also generated. For this reason, since it is difficult for a building material manufacturer to stably obtain incinerated ash that can be used as a building material, it is impossible to efficiently manufacture building materials using incinerated ash. Accordingly, incineration ash is not sufficiently effectively used, and it is the actual situation that landfill processing is performed, and it is difficult to secure a site for landfill processing.

By the way, the oil complex and the manufacturing industry are often built along the Gulf in terms of carrying in crude oil and materials, carrying out refined oil and products, or transporting. Furthermore, refining in petroleum complexes, manufacturing of chemical products, manufacturing of products in the manufacturing industry, etc. require a lot of electric power, so power plants are often built adjacent to each other. For example, even in the Asian region alone, it is recognized in several places, such as the Keiyo Rinkai Complex in Japan, Shanghai in China, Yeosu in Korea, and Singapore.
Port facilities, road traffic networks, airports, etc. have been established for the distribution of materials, raw materials, and products, as well as oil refineries, petrochemical plants, various manufacturing industries, power plants, etc. They are connected to each other by pipelines and power transmission lines in order to supply oil and materials and to supply power.
However, as mentioned above, due to various restrictions such as the cost for constructing new facilities, processing for manufacturing biochips and solid fuel, processing for use as resources such as power generation, landfill processing, etc. Although effective measures such as the use of biomass and the effective use of biofuels and resources to reduce carbon dioxide emissions have been partly implemented by each business entity or industry group, the effective reduction of carbon dioxide emissions The fact is that effective use of resources and resources has not been implemented.

As energy is supplied to the waste discharge source, an energy circulation cycle can be easily constructed, and both the energy problem and the waste treatment problem can be easily solved by reducing carbon dioxide emission. Furthermore, by installing it in a complex where the energy and materials industries are concentrated, biomass raw materials can be used in various places around the complex, for example, by using transportation routes such as harbors, railways around the port, road transportation networks, and airports.

In this way, the water vapor used for power generation is installed in the energy and materials industry accumulation area and in the nearby consumer consumption area, and the energy and material industry accumulation area and the nearby consumer university. By using water vapor in the consumption area, it can be used not only as electric energy but also as thermal energy, and more efficient energy cycle from waste can be obtained. Both energy problems and waste disposal problems can be solved. It can be solved efficiently. Furthermore, by using water vapor in facilities such as drying activated sludge and raw garbage to be used as biomass fuel, stable acquisition of biomass fuel to be used for power generation by waste treatment is easy.

By using water vapor in the consumption area, it can be used not only as electric energy but also as thermal energy, and more efficient energy cycle from waste can be obtained. Both energy problems and waste disposal problems can be solved. It can be solved efficiently. Furthermore, by using water vapor in facilities such as drying activated sludge and raw garbage to be used as biomass fuel, stable acquisition of biomass fuel to be used for power generation by waste treatment is easy.

In addition, as a settlement process, for example, the membership fee collected by this organization for the membership organization that implements maintenance management of the steam pipeline, the system 100, etc. at the association organization of the facility that uses steam is the amount of steam supply It can be illustrated as appropriating.

And in this invention, it is preferable that the said water vapor pipeline is set as the structure installed in the complex or the existing small scale facility.
In the present invention, as a steam pipeline for supplying steam after being used for power generation, a steam pipeline already installed in a complex that is an accumulation area of energy and material industries, or a newly installed small scale facility is used.
For this reason, it is possible to easily obtain an efficient circulation cycle of energy from waste simply by connecting a steam supply pipe to an existing steam pipeline, and it is easy to effectively use thermal energy. In particular, it is preferable to apply to a coastal complex that can also use a marine transportation route because the location and the steam pipeline network have already been constructed.

In the present invention, the fossil fuel obtained by the fossil fuel obtaining means is at least one of heavy oil, pulverized coal, and petroleum coke obtained from an oil refinery that refines crude oil. It is preferable.
In the present invention, as a fossil fuel used as a combustion aid, it is discharged from, for example, a degassing residue discarded from an oil refining facility for refining crude oil, an atmospheric residual oil discharged from an atmospheric distillation apparatus, or a vacuum distillation apparatus. At least one of heavy oil such as reduced-pressure residual oil, pulverized coal, and petroleum coke.
This makes it possible to remove heavy oil such as desulfurization residue, for example, waste discarded from petroleum complex, etc., atmospheric residual oil discharged from an atmospheric distillation apparatus or vacuum residue discharged from a vacuum distillation apparatus, Pulverized coal obtained by pulverizing coal used in the energy and materials industries, coal pulverized powder discharged from storage and crushers to use coal, and petroleum-derived easily obtained from petroleum complexes Since petroleum coke is used, it is easy to obtain as a combustion aid, and depending on the energy industry and the material industry, waste that is discarded as waste is used, and a better energy circulation cycle can be obtained.
In particular, pulverized coal, petroleum coke, and the like are also preferably targeted for those discharged as waste such as fine powder that needs to be used after being molded into a lump or granule for use. Furthermore, by using the dewaxing residue that is waste, incineration is performed using only the waste, so that effective use of fossil fuels such as heavy oil and coal can be obtained. In addition, you may burn as a main component the denitrification residue which mixed pulverized coal and petroleum coke together with the denitrification residue.

In the present invention, the biomass fuel acquired by the organic waste acquisition means is at least one of pulverized wood, surplus activated sludge generated by sewage treatment, rubber waste, and combustible waste. A configuration including one is preferable.
In this invention, processing is complicated, relatively large processing energy is required, and it is not actually effectively used and is processed as waste.For example, wood such as wood damaged by natural disasters, waste materials, lumber, etc. Rubber-based tires such as pulverized timber from timber, dehydrated surplus activated sludge produced by sewage treatment, activated sludge such as dry powder, combustible waste such as garbage, and metal-mixed tires Waste is used as biomass fuel.
Thus, even if incinerated in an incinerator, carbon dioxide in the atmosphere does not increase over the net, so the biomass fuel is used as so-called clean energy for the generated electrical energy. For this reason, by using the generated power in the energy and material industry gathering areas and in the nearby large consumer consuming areas, it is possible to easily construct an energy circulation cycle, and to solve both energy problems and waste disposal problems. Can be solved efficiently.

In the present invention, the organic waste acquisition means acquires at least one of plastic waste, bioethanol, and ethyl tertiary butyl ether (Ethyl Tertiary Butyl Ether), It is preferable to use a configuration in which the biomass fuel is supplied to the incinerator.

In this way, the amount of shortage required to generate steam for generating electricity from the biomass fuel with a relatively small amount of heat is discarded by using plastic waste with a relatively large amount of heat as a combustion aid. While solving the matter disposal problem, the amount of heat generation increases and the amount of power generation increases. Further, by using biomass-derived bioethanol or ETBE having a relatively large amount of heat as a combustion aid, the amount of generated power can be increased by increasing the calorific value without increasing the carbon dioxide in the net. In particular, it can be effectively used as energy without the need for separate processing due to surplus without being fully utilized. Further, by reducing the amount of fossil fuel used by using biomass-derived bioethanol or ETBE, it is possible to reduce the emission of carbon dioxide into the atmosphere generated by the combustion of fossil fuel.

Moreover, in this invention, the said organic waste acquisition means acquires the said biomass-type fuel as a dry granular material, and the said incinerator is the raw material for combustion of the said fossil fuel and the said biomass-type fuel individually, respectively, or two or more simultaneously, respectively. It is preferable to have a configuration provided with a plurality of burners to be burned.
In this invention, the fossil fuel and the biomass-based fuel acquired by the organic waste acquisition means as dry powder are individually or simultaneously burned as combustion raw materials by a plurality of burners.
For this reason, since the fossil fuel with a comparatively high calorie | heat amount and the biomass fuel with a comparatively low calorie | heat amount are burned as a combustion raw material with a burner, a fossil fuel and a biomass fuel can be burned efficiently. And, by individually burning the fossil fuel and the biomass-based fuel separately, for example, in the first burner and the second burner, the design of the burner is relatively easy and can be easily manufactured, and the combustion control is easy. it can. In addition, for example, by mixing biomass fuel and fossil fuel powder such as coal and coal coke and combusting with a single burner, the form of the burner as a combustion raw material must be the same for the powder Therefore, the design of the burner is relatively easy and can be easily manufactured, and combustion control can be easily performed.

The dried dry granular biomass fuel and the fossil fuel obtained by the fossil fuel obtaining means are input and incinerated.
This makes it possible to use a heated fluidized bed equipped with a cyclone that circulates the ceramic granulated material while heating it to a predetermined temperature and separates the ceramic granular material and the combustion gas, making it relatively difficult to granulate into a fine powder. It can be incinerated even if it is charged as a system fuel or in the form of particles or lumps, and waste can be easily processed for acquisition as a biomass fuel.

In this invention, as an organic waste acquisition means, for example, after drying or carbonizing wood, activated sludge, combustible waste, etc. with a heater, the granular material obtained by pulverizing with a pulverizer is acquired as a biomass fuel. It is configured to supply to the incinerator.
Therefore, in order to collect biomass fuel in advance, there is no need to install facilities for producing biomass fuel from waste in the raw material industry, municipalities, or local governments, and it can be used for power generation by treatment of biomass fuel waste. Stable acquisition of biomass-based fuel is easy.

Furthermore, in the present invention, it is preferable that the heater of the organic waste acquisition unit uses heat of water vapor discharged from the generator.
In this invention, after drying or carbonizing wood, activated sludge, combustible waste, etc. using the heat of water vapor discharged from the generator, the granular material obtained by pulverizing with a pulverizer is used as the biomass fuel. Acquired and supplied to the incinerator.
For this reason, for example, steam produced after using the generator for power generation, or steam generated using the residual heat of the combustion gas from the incinerator after generating the steam used for power generation, is used to produce biomass fuel. By using this, the amount of heat obtained from biomass fuel can be used more effectively. In particular, by adopting a configuration in which the generator is disposed close to the installation position, heat loss is reduced, and the configuration of a pipeline or the like for transporting water vapor can be reduced in size and simplified.

The ratio of the amount supplied to the incinerator is controlled.
This makes it possible, for example, to acquire heavy oil such as desulfurization residue and pulverized coal, fossil fuels such as petroleum coke, and waste generation such as wood waste and activated sludge due to operating conditions such as oil refining facilities. According to the acquired amount of the biomass fuel, the incineration can be stably performed in the incinerator, and the waste can be stably processed. Further, by appropriately controlling the amount of heat generated by incineration in the incinerator, the necessary power generation amount, water vapor amount, etc. can be appropriately controlled. Therefore, it is possible to provide stable energy to the energy / materials industry, as well as to nearby consumer consuming areas, and to stably treat generated waste.

Furthermore, in the present invention, the organic waste acquisition means includes a plurality of storage units that acquire the biomass-based fuel for each type, and the incineration control means is configured to use the organic waste supply means from the storage unit. It is preferable that the amount ratio of the fossil fuel and the biomass fuel is controlled according to the supply amount of each type supplied to the incinerator.
In the present invention, the fossil fuel and the biomass fuel are supplied according to the supply amount for each type supplied by the incineration control means to the incinerator by the organic waste supply means with the biomass fuel acquired for each type by the plurality of storage units. Control the quantity ratio.
By this, even if the calorific value varies depending on the type due to, for example, wood origin, activated sludge origin, combustible waste origin, etc., by recognizing the supply amount of biomass fuel for each type supplied to the incinerator according to the type, the biomass type Since the total amount of heat of the fuel can be easily recognized by calculation or the like, stable incineration in the incinerator and easy control of energy generation amount such as power generation amount and water vapor amount can be obtained.

And in this invention, it is preferable that the said calculating means is set as the structure provided with the account settlement means implemented by the firm banking constructed | assembled in the value-added communication network which manages the account settlement process of the calculated billing amount in a financial institution. .
In this invention, the settlement means of the calculation means performs the settlement process of the billed amount calculated by the farm banking constructed in the value added communication network managed by the financial institution.
As a result, the settlement of the amount charged by the supply of energy obtained from the resourced waste is automatically processed by the farm banking, so that easy operation management is obtained.

In the present invention, as a transmission line for supplying generated electric power, one already provided in a complex which is an accumulation place of energy and material industries is used.
For this reason, an efficient circulation cycle of energy from waste can be easily obtained simply by supplying the generated power to an existing transmission line via a transformer, and it is easy to effectively use electric energy. In particular, a coastal complex where a marine transportation route, which is one of the fuel transportation routes for power generation, can be used as a power station of an electric power company and a relatively large number of them are installed and a transmission line network is constructed is preferable.

As shown in FIG. 3, the heat exchanger 240 includes a water vapor generating unit 241 that generates water vapor from water, for example. The water vapor generation unit 241 is disposed in the furnace main body 231 of the incinerator 230 so as to face the incineration chamber, and generates water vapor from the water by the heat of the combustion gas in the incineration chamber.
The heat exchanger 240 is provided with a water vapor detection means (not shown) that detects properties related to water vapor such as the temperature, pressure, and quantity of the generated water vapor. This water vapor detecting means is connected to the operation control unit 300 and outputs a signal of the property relating to the detected water vapor to the operation control unit 300.
As the heat exchanger 240, for example, about 17 MPa of water vapor is generated at about 550 ° C. at 200 t / h. That is, a certain amount of electric power can be generated by the generator 250 described later by this level of water vapor.

For example, as shown in FIG. 4, the generator 250 includes a condensate steam turbine 251 connected to a heat exchanger 240. Then, the generator 250 is supplied with water vapor from the heat exchanger 240 to the condensate steam turbine 251 and rotates the condensate steam turbine 251 to generate electricity.
Further, as shown in FIG. 1, a steam supply pipe 255 is connected to the condensing steam turbine 251 of the generator 250. The steam supply pipe 255 supplies steam discharged from the condensate steam turbine 251 of the generator 250 by being used for rotation to the steam pipeline 257. This steam pipeline 257 is already installed in the Keiyo coastal complex 10. That is, the steam pipeline 257 is provided to share steam in the energy industry and the material industry.
The water vapor supply pipe 255 is provided with a water vapor amount detection means (not shown) such as a flow meter that detects the amount of water vapor that is supplied from the water vapor supply pipe 255 to the water vapor pipeline 257. The water vapor amount detection means is connected to the operation control unit 300 and outputs a signal related to the detected supply water vapor amount to the operation control unit 300.

The transformer 260 is connected to the generator 250 and is connected to an existing power transmission line 265 in the Keiyo Seaside Complex 10 as shown in FIG. The transmission line 265 transmits electric power supplied from an electric power company that is an energy industry. The transformer 260 appropriately transforms the electric power generated by the generator 250 and supplies it to the transmission line 265.
In addition, the transformer 260 is provided with supply power amount detection means (not shown) for detecting the supply power amount supplied to the power transmission line 265. The supplied power amount detecting means is connected to the operation control unit 300 and outputs a signal related to the detected supplied power amount to the operation control unit 300.

The operation control unit 300 is configured by, for example, a computer and controls the operation of the energy generation unit 200. The operation control unit 300 performs overall control of each sequencer provided for each operation part that controls the driving state of each operation part of the energy generation unit 200.
The operation control unit 300 includes an incineration control unit 310 configured as a program developed on an OS (Operating System) that controls the operation of the entire operation control unit 300.

The incineration control unit 310 controls the denitrification residue supply unit 212 and the organic waste supply unit 223, and the quantity ratio of the denitrification residue and the biomass fuel to be supplied to the incinerator 230, that is, the denitrification residue and each biomass fuel. Control the supply amount. Specifically, the incineration control unit 310 is provided in the operation control unit 300 and is input by an input operation unit (not shown) that can be input by the administrator of the resource circulation system 100, for example, incineration of each biomass fuel Based on the supply amount to the furnace 230, the combustion temperature of the incinerator 230, the generation state of water vapor and pressure, the amount of power generation, etc., the operations of the denitrification residue supply means 212 and the organic waste supply means 223 are appropriately controlled. Then, the supply amount of the degassing residue to the first burner 232 and the supply amount of each biomass fuel to the second burner 233 are set to a predetermined ratio.
The predetermined ratio of the supply amount is, for example, when the setting item is the supply amount of each biomass fuel to the incinerator 230, the supply ratio of each biomass fuel, or the supply ratio of the biomass fuel and the desulfurization residue, The operations of the dewaxing residue supply means 212 and the organic waste supply means 223 are controlled so that each carry-out amount corresponds to the set item.
Further, when the setting item is the combustion temperature of the incinerator 230, the biomass is set so that the detected temperature in the incinerator becomes the set combustion temperature based on the signal related to the temperature in the incinerator output from the temperature detecting means. Control is performed so that the system fuel and degassing residue are appropriately supplied. That is, since the calorific value of biomass fuel varies depending on the type of wood-derived, activated sludge-derived, combustible waste, etc., the amount of heat of the entire biomass-based fuel combusted in the incinerator 230 depends on the type of biomass-based fuel supplied. If the supply amount of degassing residue to be supplied is known, the total amount of combustion heat in the incinerator 230 can be calculated. For this reason, the control is performed so that the biomass fuel and the degassed residue are supplied at a predetermined ratio so as to adjust the amount of heat corresponding to the excess and deficiency of the temperature in the incineration chamber with respect to the set combustion temperature.
Furthermore, when the setting item is the generation state of water vapor, the incinerator 230 is set so that the generation state of water vapor is set based on the signal regarding the property of the water vapor generated in the heat exchanger 240 output from the water vapor detection means. Control for changing the temperature in the incineration chamber, that is, the supply amount of the biomass fuel and denitrification residue is appropriately controlled.
Similarly, when the setting item is the power generation amount, the pressure and amount of water vapor supplied to the generator 250 are controlled based on a signal related to the power supply amount output from the power supply amount detection means of the transformer 260. That is, the supply amounts of the biomass-based fuel and the denitrification residue are appropriately controlled so that the amount of heat in the incinerator 230 can be obtained in a state where predetermined steam is supplied.
In this way, operation control for extracting energy from waste can be performed according to the supply state of the denitrification residue and the supply state of each biomass fuel.

  In addition, the operation control unit 300 compares the operation state of each operation part with a preset threshold value, constantly monitors whether or not it is in an abnormal operation state, and recognizes that the operation state is an abnormal operation state. It is also possible to perform control for notifying the user or stopping the operation.

The system control unit 400 performs a settlement process by supplying energy generated by the operation of the resource circulation system 100.
The system control unit 400 is configured by a computer, for example, and is connected to the operation control unit 300 so as to be able to transmit and receive. As the connection between the system control unit 400 and the operation control unit 300, for example, information is transmitted through the Internet, an intranet, a LAN (Local Area Network), or a wireless medium based on a general-purpose protocol such as TCP (Transmission Control Protocol) / IP (Internet Protocol). Examples include a network such as a communication line network or a broadcast network in which a plurality of base stations capable of transmitting and receiving a network constitute a network, and a wireless medium itself as a medium for direct transmission and reception such as a wireless LAN. Here, any medium such as radio waves, light, sound waves, and electromagnetic waves can be applied as the wireless medium.
The system control unit 400 includes a power sale bill calculation unit 410 and a water vapor bill calculation unit 420 configured as programs developed on an OS (Operating System) that controls the operation of the entire system control unit 400. And settlement means 430.

The power sale bill calculation means 410 calculates a power sale charge amount charged to the power company that supplies power to the transmission line 265 based on the supply power amount detected by the supply power amount detection means.
The water vapor sales bill calculation means 420 calculates the amount of water vapor supply charged to the facility connected to the water vapor pipeline 257 and using water vapor based on the amount of water vapor supplied detected by the water vapor amount detection means.
The settlement means 430 carries out settlement processing of the calculated billed amount by firm banking built in a value-added communication network managed by a financial institution. The settlement means 430 not only automatically performs settlement processing by firm banking, but also displays processing for prompting the manager to perform settlement processing by displaying a bill invoice or printing it out. The printing process may be implemented as a settlement process.

[Operation of resource circulation system]
Next, the operation of the one embodiment will be described.

First, degassing residue discarded by refining crude oil at an oil refining facility 11 such as a refinery is introduced and stored in a dewatering residue tank 211 of the dewaxing residue acquisition means 210 by, for example, a pipeline. For example, an inflow amount is detected during the storage, and the operation control unit 300 supplies the desulfurization residue to the desulfurization residue tank 211 on the basis of a signal relating to the storage amount of the desulfurization residue detected by a desulfurization residue amount detection unit (not shown). Monitor and control the inflow.
On the other hand, the biomass fuel is acquired by the organic waste acquisition means 220. For example, when a biomass fuel already granulated into fine powder is carried in, it is directly put into the biomass tank 222 and stored. Further, when a granulated material such as a so-called biochip is carried in, it is pulverized and granulated into a fine powder having a predetermined average particle diameter by the pulverizer 221B of the pretreatment unit 221, and the biomass tank 222. To input. Furthermore, when unused wood materials, activated sludge cakes, combustible garbage such as raw garbage are carried in, they are dried or carbonized by the heating machine 221A of the pretreatment unit 221, and then pulverized into fine powder by the pulverizer 221B. And granulated and put into the biomass tank 222. In addition, when putting into the biomass tank 222, it inputs according to the classification of the waste from which it originates.

Then, the operation control unit 300 controls the denitrification residue supply unit 212 and the organic waste supply unit 223 on the basis of the setting items input by the administrator (not shown) in the input operation unit, and denitrification residue tank 211. Is supplied to the first burner 232 of the incinerator 230, and each biomass fuel stored in each biomass tank 222 is supplied to the second burner 233 of the incinerator 230 to be burned. As described above, the desulfurization residue and the biomass fuel are supplied at a predetermined supply rate and supply amount according to the set items.
During combustion of biomass fuel in the incinerator 230, lime cake is mixed in the biomass fuel or lime cake is separately supplied to the incinerator 230, so that sulfur generated relatively much due to combustion of the denitrification residue. The fraction reacts with calcium in the lime cake and is removed from the combustion gas as calcium sulfate, that is, desulfurized. Calcium sulfate generated by this desulfurization accumulates in the lower part of the furnace main body 231 of the incinerator 230 together with ash generated from combustion of the desulfurization residue and biomass fuel, and is discharged from the dust recovery unit 231A, for example, building materials of the raw material industry Used as a raw material for building materials by the manufacturer 14.

Then, by the combustion in the incinerator 230, the steam generator 241 of the heat exchanger 240 uses the steam generated from the degassing residue and the property corresponding to the supply ratio and supply amount of each biomass fuel to generate the generator 250. The condensate steam turbine 251 is rotated and power is generated by the generator 250.
The electric power generated by the generator 250 is appropriately transformed by the transformer 260 and supplied to the existing transmission line 265 in the Keiyo coastal complex 10.
When the generated power is supplied to the transmission line 265, the operation control unit 300 receives a signal related to the amount of power supplied detected by the power supply amount detecting means, for example, a screen display on the display means or a print output on the printing means. To notify the administrator in a recognizable manner.
In addition, the operation control unit 300 outputs a signal related to the supplied power amount to the system control unit 400.

In addition, the operation control unit 300 controls, for example, a valve or the like to rotate the condensate-type steam turbine 251 generated by the combustion of the desulfurization residue and the biomass-based fuel and discharge the steam from the generator 250 to the steam supply pipe. The steam is supplied to the steam pipeline 257 through 255.
When supplying the water vapor to the water vapor pipeline 257, the operation control unit 300 receives a signal related to the amount of water vapor detected by a water vapor amount detecting means (not shown), for example, a screen display on the display means or a print output on the printing means. To notify the administrator in a recognizable manner.
In addition, the operation control unit 300 outputs a signal related to the supplied water vapor amount to the system control unit 400.

The system control unit 400 that has received the signal regarding the amount of power supplied and the amount of water vapor supplied to the power company that supplies power via the power transmission line 265 according to the amount of power supplied by the power sales invoice calculation means 410. To calculate the amount charged for selling electricity.
Further, the system control unit 400 uses the water vapor bill calculation means 420 to charge the water vapor supply amount charged to the material industry that is connected to the water vapor pipeline 257 and uses the water vapor according to the received water vapor amount. Is calculated. For billing to this material industry, for example, it is charged according to the amount of use for each company using steam, and maintenance management of the steam pipeline and the system 100 is carried out by an association of facilities using steam. For example, it may be billed to a membership organization that collects membership fees.
Then, the system control unit 400 uses the settlement means 430 to perform the settlement process of the power billing amount and the water vapor supply amount, which are the calculated billing amounts, for example, farm banking built in a value-added communication network managed by a financial institution To implement.

[Effects of Embodiment]
As described above, in the above-described embodiment, the defoaming residue discarded from the oil refining facility 11 for refining crude oil and acquired by the dewaxing residue acquisition unit 210, the biomass fuel acquired by the organic waste acquisition unit 220, and Is burned in the incinerator 230. Then, steam is generated from the combustion gas generated in the incinerator 230 by heat exchange in the steam generator 241 of the heat exchanger 240. Then, the generated steam is used to rotate the condensate steam turbine 251 of the generator 250 to generate power, and the power generated via the transformer 260 is supplied to the transmission line 265 that supplies power at the power company. That is, the combustion aid is used to remove the degassing residue, which is a waste having a relatively large amount of heat, from a shortage of the amount of steam required to generate power from the biomass fuel derived from the waste having a relatively small amount of heat by the generator 250. It is burned as.
In this way, for example, pulverized wood from waste wood resources such as sawdust produced by natural disasters and pests, waste wood, sawdust, etc., dehydrated surplus activated sludge produced by sewage treatment, Relatively large energy to process as solid fuel called so-called biochip, such as activated sludge granules such as dry powder, combustible waste such as garbage, and so on. Is required to be incinerated together with the degassing residue discharged as waste from the oil refining facility 11 to generate effective electrical energy. As a result, it is possible to recover from the waste that is simply incinerated as effective electrical energy, and it is also easy to secure a landfill because no processing such as landfilling of the waste is required.
For this reason, in particular, facilities for processing as solid fuel only by installing in areas where energy and material industry accumulation areas and consumer consumption areas such as oil complexes recognized prominently in Japan are close, There is no burden of constructing facilities for generating energy from solid fuel at each company, industry association, or municipality, and waste that is not actually used effectively can be used effectively as a resource. As energy is supplied to the waste discharge source, an energy circulation cycle can be easily constructed, and both the energy problem and the waste treatment problem can be easily solved by reducing carbon dioxide emission. Furthermore, by installing it in a complex where the energy and materials industries are concentrated, biomass raw materials can be used in various places around the complex, for example, by using transportation routes such as harbors, railways around the port, road transportation networks, and airports. It is also easy to recover from. That is, it is preferable to install in a complex, particularly a coastal complex that can also use a sea transportation route. Furthermore, the Keiyo Rinkai Complex 10 is suitable because it has a large amount of materials and materials to be carried in and out via ports, airports, roads, etc., and is a gathering place for various material industries, as well as a large consumer consuming area in the metropolitan area. .

Then, the amount of power supplied from the transformer 260 to the power transmission line 265 is detected by the supply power amount detection means, and the power company is billed by the power sales bill calculation means of the system control unit based on the detected power amount. The power billing amount is calculated and settled.
For this reason, the construction of the energy circulation cycle automatically calculates the power sales invoice associated with the supply of electrical energy based on the supply of electrical energy obtained and supplied by incineration of waste. Effective and useful operation of the circulation system 100 can be easily achieved.

Further, as the power transmission line 265 for supplying the generated power, the one already provided in the Keiyo coastal complex 10 which is an accumulation place of energy and material industries is used.
For this reason, an efficient circulation cycle of energy from waste can be easily obtained simply by supplying the generated power to the existing transmission line 265 via the transformer 260, and it is easy to effectively use electric energy. Can be.

In addition, the processing is complicated, requires relatively large processing energy, is not effectively used in practice, and is treated as waste, for example, from unused wood resources such as sawdust generated from damaged trees, waste wood, lumber, etc. Pulverized wood waste, surplus activated sludge dehydrated wastewater produced by sewage treatment, activated sludge such as dry powder, combustible waste such as garbage, rubber waste such as tires mixed with metal Is used as biomass fuel.
Thus, since carbon dioxide in the atmosphere does not increase over the net even when incinerated in the incinerator 230, biomass fuel is used as so-called clean energy for the generated electrical energy. For this reason, by using the generated power in the energy and material industry gathering areas and in the nearby large consumer consuming areas, it is possible to easily construct an energy circulation cycle, and to solve both energy problems and waste disposal problems. Can be solved efficiently.

In addition, the use of non-combustible waste generated in large consumer areas, plastic wastes that are relatively high in heat, such as plastics that cannot be reused as defective products from the materials industry, and those that have relatively high amounts of heat are limited. The surplus bioethanol or biomass-derived ETBE is used together with biomass fuel.
In this way, by using a plastic waste having a relatively large amount of heat as a combustion aid, a shortage in order to generate steam for generating a biomass fuel having a relatively small amount of heat with the generator 250, While solving the waste disposal problem, the amount of generated heat can be increased to increase the amount of power generation. Further, by using biomass-derived bioethanol or ETBE having a relatively large amount of heat as a combustion aid, the amount of generated power can be increased by increasing the calorific value without increasing the carbon dioxide in the net. In particular, it can be effectively used as energy without the need for separate processing due to surplus without being fully utilized. In addition, by reducing the amount of degassing residue used by using biomass-derived bioethanol or ETBE, it is possible to reduce carbon dioxide emissions into the atmosphere generated by combustion of the degassing residue.

Then, steam that is used for power generation from the heat exchanger 240 and discharged from the generator 250 is supplied to the steam pipeline 257 via the steam supply pipe 255. Then, the amount of water vapor supplied by the water vapor amount detecting means is detected, and the water vapor bill calculating means 420 of the system control unit 400 is connected to the water vapor pipeline 257 based on the detected amount of supplied water vapor to use the water vapor. It calculates and settles the amount of steam supply billed to the industry and material industry.
In this way, the water vapor used for power generation is used in the energy industry and the materials industry, and the water vapor pipeline 257 installed in the nearby consumer high consumption area. By using water vapor in large consumer consuming areas, it can be used not only as electric energy but also as heat energy, and more efficient cycle of energy from waste can be obtained. Both of these can be solved efficiently. Furthermore, by using water vapor in facilities such as drying activated sludge and raw garbage to be used as biomass fuel, stable acquisition of biomass fuel to be used for power generation by waste treatment is easy. Become.

Moreover, what is already provided in the Keiyo seaside complex 10 which is an accumulation place of an energy industry and a material industry is used as the steam pipeline 257 which supplies the water vapor | steam after utilizing for an electric power generation.
For this reason, simply connecting the steam supply pipe 255 to the existing steam pipeline 257 makes it possible to easily obtain an efficient circulation cycle of energy from waste, and to easily use heat energy effectively.

Then, the degassing residue is burned by the first burner 232 of the incinerator 230, and the dry fine powder granulated to, for example, several μm to several hundred μm by the organic waste acquisition means 220 by the second burner 233 of the incinerator 230. The biomass fuel obtained in the form is burned.
For this reason, since the denitrification residue having a relatively high calorific value and the biomass fuel having a relatively low calorific value are burned by the independent burners 232 and 233, the design of the burners 232 and 233 is relatively easy and easy. It can be manufactured and combustion control can be easily performed.

Further, as organic waste acquisition means 220, wood, activated sludge, combustible waste, etc. are dried or carbonized using the heat of steam discharged from the generator 250 by the heater 221A, and then pulverized by a pulverizer. The obtained granular material is obtained as biomass fuel and supplied to the incinerator 230.
For this reason, it is not necessary to provide a facility for producing biomass fuel from waste in the raw material industry, municipalities, or local governments in order to collect pre-granulated biomass fuel, and by processing biomass fuel waste Stable acquisition of biomass fuel used for power generation becomes easy.
Furthermore, for example, steam generated after using the generator 250 for power generation, steam generated using the residual heat of the combustion gas in the incinerator 230 after generating steam used for power generation, etc. of the biomass fuel By using it for production, the amount of heat obtained from biomass fuel can be used more effectively. In particular, by adopting a configuration in which the generator is disposed close to the installation position, heat loss is reduced, and the configuration of a pipeline or the like for transporting water vapor can be reduced in size and simplified.

Further, the incineration control means 310 of the operation control unit 300 supplies the dewaxing residue acquired by the denitrification residue acquisition means 210 to the incinerator 230 by the denitrification residue supply means 212, and the organic waste supply means 223 supplies the organic matter. The amount ratio of the biomass fuel acquired by the waste acquisition means 220 to the amount supplied to the incinerator 230 is controlled.
As a result, for example, the biomass fuel according to the amount of denitrification residue acquired under the operating conditions of the oil refining facility 11 and the amount of waste such as timber waste and activated sludge that are unused wood resources. According to the acquired amount, incineration can be stably performed in the incinerator 230, and a stable treatment of waste can be obtained. In addition, by appropriately controlling the amount of heat generated by incineration in the incinerator 230, the necessary power generation amount, water vapor amount, and the like can be appropriately controlled. Therefore, it is possible to provide stable energy to the energy / materials industry, as well as to nearby consumer consuming areas, and to stably treat generated waste.

Then, the biomass fuel obtained for each type of waste derived from the plurality of biomass tanks 222 by the incineration control means 310 is separately or mixed into the incinerator 230 by the organic waste supply means 223 provided in each biomass tank 222. Thus, the amount ratio of denitrification residue and biomass fuel is controlled according to the supply amount for each type supplied.
By recognizing the supply amount of biomass-based fuel for each type supplied to the incinerator 230 according to the type, for example, even if the calorific value varies depending on the type due to, for example, wood origin, activated sludge origin, combustible waste origin, etc. Since the total amount of heat of the system fuel can be easily recognized by calculation or the like, more stable incineration in the incinerator 230 and easy control of the amount of energy generated such as the amount of power generation and the amount of water vapor can be obtained.

Furthermore, the sugar-making waste (lime cake) which has calcium as a main component discarded by sugar-making processing is acquired with the organic waste acquisition means 220, and is supplied to the incinerator 230 with biomass fuel.
As a result, sulfur generated by incineration of crude oil-derived desulfurization residue and the like is desulfurized by calcium of the sugar production waste supplied to the incinerator 230 together with the biomass fuel, and the addition of a desulfurizing agent is not required or added in a small amount. Waste can be removed in quantity and both sugar processing waste and sulfur desulfurization resulting from incineration can be obtained. In addition, by installing at the Keiyo Rinkai Complex 10 where the energy and materials industries are concentrated, even if there are no sugar production facilities at the energy and materials industries, the sugar can be collected from various locations using the port. Easy. Furthermore, calcium sulfate, which is gypsum generated by desulfurization, can be used as a building material, and further resource recycling can be obtained by using it in the material industry in an energy and material industry cluster. In addition, since the ash content from combustion is inorganic, it can be used as a building material together with gypsum, and the landfill treatment of ash content by incineration is not required, so that it can be effectively used as a resource.
And since it is the structure which puts a lime cake into the incinerator 230, the load of the desulfurization process in the combustion gas processing part 234 which processes combustion gas can be reduced. Therefore, simplification and miniaturization of equipment for the desulfurization treatment can be obtained.
Further, a dust recovery unit 231A for recovering ash and calcium sulfate is provided at the bottom of the furnace body 231 of the incinerator 230. That is, since it is a boiler-type incinerator 230 that is burned by the burners 232 and 233, a dust recovery unit 231A can be provided and recovered as ash or calcium sulfate.

Then, the settlement processing 430 of the system control unit 400 performs settlement processing of the power billing amount and the water vapor supply amount, which are the calculated billing amounts, by, for example, firm banking built in a value-added communication network managed by a financial institution We are carrying out.
For this reason, since the settlement of the power sales billing amount and the water vapor supply amount billed by the supply of energy obtained from the resourced waste can be automatically processed by the farm banking, easy operation management can be performed.
Furthermore, as a settlement process, for example, the membership fee collected by this organization for the membership organization that implements maintenance management of the steam pipeline, the system 100, etc. at the association organization of the facility that uses steam is the amount of steam supply As a result, the cooperation between energy and material industries, as well as municipalities and local governments will become stronger, and effective solutions to each other's energy and waste disposal problems will function smoothly and effectively. it can.

The aspect described above shows one aspect of the present invention, and the present invention is not limited to the above-described embodiment, and is within a range in which the object and effect of the present invention can be achieved. Needless to say, modifications and improvements are included in the content of the present invention. In addition, the specific structure and shape when implementing the present invention can be applied to other structures and shapes as long as the objects and effects of the present invention can be achieved.

  That is, as described above, the present invention is not limited to the case where the present invention is applied to the Keiyo Coastal Complex 10, but can also be applied to the coastal complex in each district, the inland industrial zone, and the like.

And although the structure which burns a desulfurization residue as a combustion adjuvant was illustrated, it is not restricted to a desulfurization residue, For example, the normal pressure residual oil discharged | emitted from an atmospheric distillation apparatus, the pressure reduction residual oil discharged | emitted from a vacuum distillation apparatus Various fossil fuels such as heavy oil, pulverized coal that is a fine powder of coal, petroleum-derived petroleum coke, and the like may be used.
In particular, defoaming residue that is fossil fuel discharged as waste, fine powder of coal and petroleum coke are preferable, and defoaming residue that is a waste that is difficult to reuse compared to pulverized coal and petroleum coke is particularly preferable. preferable.
Furthermore, the degassing residue was burned by the first burner 232. For example, when burning pulverized coal or petroleum coke, for example, separate burners are used, or degassing residue, pulverized coal, petroleum coke, etc. Various configurations such as mixing and burning with a single burner can be applied. Further, the degassing residue may be burned by combustion in the first burner 232, and pulverized coal or petroleum coke may be mixed with biomass fuel and burned in the second burner 232.

  In addition, it has been explained in the form of processing various types of waste as biomass fuel, but only activated sludge is unused, depending on the facility situation around the installation location and the form of waste collection / collection, for example. It is good also as a structure which incinerates only with wood resources, only garbage, only rubber-type waste, or any combination. And it is not necessary to use the plastic waste, bioethanol, etc. which are nonflammable garbage. Furthermore, various calcium-based wastes may be used without using sugar-making waste.

Moreover, although the boiler type | mold was illustrated as the incinerator 230 which burns a desulfurization residue and biomass-type fuel, for example, as shown in FIG.
That is, the fluidized bed incinerator 500 shown in FIG. 5 is a heating device provided with a cyclone 510 that circulates ceramic powder such as sand while heating it to a predetermined temperature and separates the ceramic powder and combustion gas at the upper part. A combustor 520 as a fluidized bed is provided. The combustor 520 is provided with a combustion raw material charging unit (not shown) for charging degassing residue and biomass fuel therein. The cyclone 510 is connected to a duct 530 that distributes the separated combustion gas. A steam generation unit 241 that generates steam by heat exchange is provided in the duct 530. A combustion gas processing unit 234 is connected to the duct 530 to process and exhaust the combustion gas.
In the fluidized bed type shown in FIG. 5, the biomass fuel to be incinerated may be a granular material having a diameter of about several centimeters, for example, and does not need to be pretreated into a fine powder and can be easily processed. That is, since the combustor 520 provided with the cyclone 510 that separates the ceramic granule and the combustion gas by circulating the ceramic granule while heating it to a predetermined temperature is used, it is a biomass fuel that is relatively difficult to granulate. However, for example, it can be incinerated even if it is put in the form of particles or lumps having a particle size of about several centimeters, and waste can be easily processed for acquisition as a biomass fuel. Furthermore, the technology of fluid catalytic cracking (FCC) towers used in, for example, petroleum refining may be diverted, and it is not necessary to construct a special burner or equipment for incinerating biomass fuels. Manufacturing and operation control can be obtained relatively easily.
As described above, as in the above-described embodiment and the embodiment shown in FIG. 5, a boiler type, a fluidized bed type, and other various configurations can be used as the configuration of the incinerator that generates water vapor for power generation.

Moreover, although the structure provided with the condensate type | mold steam turbine 251 was illustrated as the generator 250 to generate electric power using water vapor | steam, the structure of any steam turbine which uses water vapor | steam is applicable.
The heater 221A is not limited to a configuration in which waste is dried or carbonized by using the steam used for power generation. For example, a heater 221A is separately provided in the vicinity of a facility for treating waste or a place where biomass fuel is accumulated. It may be provided, and may be dried or carbonized by heating separately at these facilities and collection sites.
Then, as described above, the biomass fuel is inserted or carbonized by the heater 221A provided in the facility or collection place for treating the waste as described above, and further pulverized in advance by the pulverizer 221B. It is good also as a structure which acquires what was manufactured as. By adopting such a configuration, it is possible to improve efficiency such as a reduction in transportation cost due to volume reduction of waste.
In addition to supplying steam to the steam pipeline 257, the steam can be used for various types of heating, such as waste treatment, heating of degassing residue, and preheating of air for combustion in the incinerator 230. Further, not only the steam pipeline 257 but also a newly established one may be used.

Then, water vapor used for power generation from the heat exchanger 240 and discharged from the power generator 250 is supplied to the water vapor pipeline 257 via the water vapor supply pipe 255. And the energy industry which uses water vapor, or the material industry detects the amount of water vapor used by extracting water vapor from the water vapor pipeline 257 by the water vapor usage amount detection means, and the water vapor usage fee calculation means of the calculation means detects the amount of water vapor used. It is good also as a structure which calculates the water vapor utilization billing amount charged with respect to a facility based on.
In this way, the water vapor used for power generation is used in the energy and material industry accumulation areas, and also in the nearby consumer high consumption areas, using the water vapor pipeline 257, the energy and material industry accumulation areas and the adjacent consumer areas. By using water vapor in large consumption areas, it can be used not only as electric energy but also as heat energy, and more efficient energy circulation cycle from waste can be obtained, both energy problems and waste disposal problems. Can be solved efficiently. Furthermore, by using water vapor in facilities such as drying activated sludge and raw garbage to be used as biomass fuel, stable acquisition of biomass fuel to be used for power generation by waste treatment is easy. Become.
