1 is a configuration diagram of a waste disposal system according to an embodiment of the present invention.

Next, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention.
As shown in FIG. 1, a waste treatment system 10 according to an embodiment of the present invention is roughly provided with a waste treatment facility 11, a power generation facility 12, and a bioethanol production facility 13.

The waste treatment facility 11 includes a melting furnace (or an incinerator, both of which are examples of a furnace) 21 and a combustion device 22 and incinerate combustible waste.

In the melting furnace 21, combustible waste is processed. In this treatment process, combustible gases (carbon monoxide, hydrogen, methane, etc.) are generated in the course of drying and pyrolysis.
The combustion device 22 burns combustible gas generated in the melting furnace 21. Pilot kerosene is used as fuel for igniting the combustion chamber of the combustion device 22.

The power generation facility 12 includes a boiler 31, an external superheater 32, a turbine 33, and a condenser 34.
The boiler 31 generates steam using high-temperature exhaust gas (waste heat) emitted from the combustion device 22. The material of the piping of the boiler 31 is carbon steel. This exhaust gas contains sulfur and chlorine and is known to cause high temperature corrosion of carbon steel used in the piping of the boiler 31. Therefore, the steam temperature cannot be heated to a temperature higher than 400 ° C., for example. The exhaust gas used as a heat source in the boiler 31 is purified by the exhaust gas cleaning device 35 and released to the atmosphere.

The external superheater 32 heats the steam generated in the boiler 31. When the external superheater 32 further increases the superheat degree of the steam, steam (superheated steam) having a higher superheat degree (heat amount) is generated. The external superheater 32 combusts recovered oil (described later) obtained from food waste to burn a first burner (not shown) as a heat source and a second burner (not illustrated) as a heat source by burning ethanol (described later). (Shown). A water pipe for cooling the main body is passed through the casing portion of the external superheater 32.

The turbine 33 drives a generator (not shown) connected to the rotating shaft of the turbine 33. The turbine 33 is rotated by superheated steam generated by the external superheater 32.
The condenser 34 condenses the steam emitted from the turbine 33.

The bioethanol production facility 13 includes a pretreatment device 41, a saccharification device 42, a three-phase centrifugal separation device (an example of a separation device) 43, a fermentation device 44, and a distillation device 45, and produces bioethanol using food waste as a raw material. . Here, food waste includes food waste from households (household garbage), food-related industrial waste from food factories, and foods discarded at the distribution stage (waste confectionery, convenience stores, etc. Expired foods, leftovers from restaurants, etc.), food wastes from hospitals, etc., fruits removed to increase sugar content during supply and demand adjustment and production (business-related garbage), etc. Includes any waste generated during the production, processing, cooking and eating and drinking stages.

The pretreatment device 41 crushes and sorts food waste, and removes foreign matters such as plastic and vinyl.

The saccharification apparatus 42 adds an enzyme such as glycol amylase to the food waste from which the contaminants have been removed, and holds it at about 60 ° C., thereby converting the starch in the food waste into glucose and dissolving it in water. A liquid is produced. The saccharification device 42 is provided with a screen such as a vibration sieve or a screw press (not shown), which leaves fibers, plastics, paper, bags, disposable chopsticks, metal, and crustaceans contained in the saccharified solution. As removed.
Thus, by processing with the saccharification apparatus 42, the collection amount of the oil content in food waste can be increased. For example, the oil content attached to the tempura garment is hydrolyzed starchy from the tempura garment and released in a liquid form into the saccharified solution, so that the amount of oil recovered is increased.

The three-phase centrifuge 43 separates the saccharified solution into three phases, an oil component, an aqueous solution component, and a solid component. The separated oil is supplied to the external superheater 32 as fuel. Here, the temperature of the oil immediately after separation is 60 ° C. However, the temperature of the oil component decreases during the transfer, and solidifies when the oil temperature is lower than 30 ° C. Therefore, it is difficult to transfer the oil component through the transfer tube. Therefore, a buffer tank (not shown) for temporarily storing oil is provided at the subsequent stage of the three-phase centrifuge 43, the temperature of the oil is maintained in the buffer tank, and the transfer pipe is kept warm by a steam trace or the like. To the external superheater 32. This steam degree trace can be realized by, for example, winding a steam pipe around the outer periphery of the transfer pipe. Thus, in order to maintain fluidity while being transferred from the three-phase centrifuge 43 to the external superheater 32, the temperature of the oil component is maintained at 30 ° C. or higher and lower than 60 ° C., preferably 30 ° C. or higher and lower than 35 ° C. The The separated oil has a quality equivalent to a low sulfur and low chloride A heavy oil.
On the other hand, the separated aqueous solution is sent to the fermentation apparatus 44 as a sugar solution. The solid content is sent to the melting furnace 21 as a residue and processed.

The fermenter 44 adds yeast to the sugar solution obtained by the three-phase centrifuge 43 and generates an ethanol fermentation solution by, for example, continuous fermentation.

The distillation apparatus 45 distills ethanol of the ethanol fermentation liquid produced in the fermentation apparatus 44. The ethanol concentration of distilled ethanol is, for example, 85 to 95 wt%. This distilled ethanol is supplied to the external superheater 32 as a fuel. In addition, a distillation waste liquid is produced | generated in the process of distillation. A part of this distilled waste liquid is reused as water used in the saccharification device 42, and the rest is incinerated by the combustion device 22. Alternatively, the distilled waste liquid is detoxified by a wastewater treatment apparatus (not shown) and then discharged into sewage or the like.

Next, a waste processing method using the waste processing system 10 will be described.
In the waste treatment facility 11, for example, when waste (combustible waste) is charged into the melting furnace 21, combustible gas is generated. This gas is combusted by the combustion device 22, and the high-temperature gas generated at that time becomes a heat source of the boiler 31 (step A). In addition, when waste is thrown into an incinerator, waste is directly combusted and the high temperature gas produced | generated at the time of this combustion becomes a heat source of the boiler 31.

In the bioethanol production facility 13, food waste in the waste is pretreated by the pretreatment device 41. In the pretreatment device 41, impurities mainly composed of plastic are removed from the food waste. This contaminant is sent to the melting furnace 21. The food waste from which the impurities are removed is saccharified by an enzyme in the saccharification device 42 to produce a saccharified solution (step C). The produced saccharified solution is separated into three phases of oil, aqueous solution, and solid by the three-phase centrifugal separator 43 (step D). Of these, the oil is sent as recovered oil to the external superheater 32 as fuel. The aqueous solution is sent to the fermentation apparatus 44. The solid content is melted in the melting furnace 21 (or incinerated in an incinerator). In the fermentation apparatus 44, an ethanol fermentation liquid is produced by yeast (step G). The ethanol fermentation liquid is distilled by the distillation apparatus 45 to produce an ethanol liquid (Step H). The generated ethanol solution is sent to the external superheater 32 as fuel.
In the bioethanol production facility 13, a dehydrating device (not shown) may be further provided, and a part of the ethanol solution generated by the distillation device 45 may be introduced into this dehydrating device. The dehydrating apparatus separates water from the ethanol solution concentrated in the distillation apparatus 45 by membrane separation, azeotropic distillation, PSA method, or the like, thereby generating anhydrous ethanol (anhydrating step). The purified absolute ethanol can be used as ETBE or E3 gasoline.

In the power generation facility 12, the heat generated from the combustion device 22 is used to generate steam in the boiler 31 (process B). In general, the exhaust gas emitted from the combustion device 22 contains a lot of corrosive dust such as sulfur, chloride, and heavy metals. Therefore, in order to avoid corrosion of the boiler 31, the temperature of the exhaust gas for heat recovery by the boiler 31 needs to be suppressed to 400 ° C. or less.
In the present embodiment, the steam generated in the boiler 31 is introduced into the external superheater 32 and heated to generate superheated steam with a higher degree of superheat (generated in step B using oil as a heat source). The step of further increasing the degree of superheat of the generated steam and generating superheated steam is referred to as Step E. The step of further increasing the degree of superheat of the steam generated in Step B using ethanol as a heat source and generating superheated steam is referred to as Step I. ). The temperature of this superheated steam is, for example, 430 ° C.
Here, the heat source of the external superheater 32 is recovered oil separated by the three-phase centrifuge 43 and ethanol distilled by the distillation device 45. Thus, the recovered oil that has not been effectively used in the past can be used as the fuel for the external superheater 32 as it is.
In particular, the recovered oil and ethanol have less sulfur and chloride content than the exhaust gas from the combustion device 22. Therefore, even if the material of the piping inside the external superheater 32 is made of carbon steel which is cheaper than stainless steel, there is no fear that the piping will deteriorate due to high temperature corrosion, and it is possible to heat the steam at over 400 ° C. Therefore, it is possible to raise the temperature by heating steam (for example, 400 ° C., 40 ata) sent from the boiler 31. As a result, superheated steam having a higher degree of superheat (amount of heat) is generated. By sending this to the turbine 33, it is expected that the power generation efficiency will be improved by, for example, 1 to 3%.

In addition, from the external superheater 32, the exhaust gas of 600 degreeC, for example comes out. By sending this exhaust gas to the boiler 31 and recovering waste heat, the heat can be effectively used. Further, the exhaust gas can be processed by the exhaust gas cleaning device 35.

Thereafter, the superheated steam generated by the external superheater 32 rotates the turbine 33. Thereby, the generator which is not illustrated is driven and electric power is generated (process F). The steam emitted from the turbine 33 is condensed in the condenser 34 and sent to the boiler 31 for circulation.

In addition, this invention is not limited to the above-mentioned embodiment, The change in the range which does not change the summary of this invention is possible. For example, a case where the present invention is configured by combining some or all of the above-described embodiments and modifications is also included in the technical scope of the present invention.
In particular, the external superheater 32 has the first and second burners, but may have only one. That is, at least one of the recovered oil and ethanol may be a heat source.

In addition, the power generation facility 12 collects the collected oil and generated ethanol in a time zone in which the power selling fee for the power company is higher than a predetermined amount (for example, from 8:00 to 22:00 when the power selling fee is higher than midnight). The external superheater 32 may be operated using at least one of them as a heat source to improve power generation efficiency. By adopting such an operation method, it is possible to further increase the income from power sale and to further reduce the running cost of the waste treatment system 10. In this case, the bioethanol production facility is always operated, and the bioethanol and the recovered oil generated during the time period when the external superheater 32 is not operated are liquid fuel having a large amount of heat per unit volume, and are stored in the buffer tank. Just keep it. Note that the external superheater 32 may be operated using at least one of the collected oil and generated ethanol only as a heat source only during a time period in which the power selling fee is higher than a predetermined amount.
Moreover, an incinerator can also be used as a furnace instead of a melting furnace.
