Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste disposer for reducing the amount of food waste that has been thrown in, and more specifically to a food waste that is more environmentally friendly by effectively utilizing waste energy. The present invention relates to a processing system and a garbage processing machine.

[0002]

2. Description of the Related Art Conventionally, garbage such as leftover food, scraps of vegetables and fruits, bones and shells of seafood, etc. generated at home, restaurants, food processors etc. may be incinerated at an incineration facility. There were many. However, since such garbage contains a large amount of water, it lowers the temperature of the incinerator and causes a decrease in combustion efficiency, and since it contains various components, it causes dioxins.

Therefore, a food waste processing machine has already been proposed as a device for reducing the amount of food waste, and in recent years, its needs have been particularly increased. The main types of this food waste processing machine are generally so-called microbial decomposition type and dry type. In a microbial decomposition type food waste processing machine, a medium mixed with microorganisms is stored in a processing container, and the garbage is mixed with this medium to decompose the garbage by the microorganisms in the medium and reduce (or reduce) the garbage. It is designed to let you. In addition, in a dry-type food waste processing machine, generally, food waste is put into a processing container, and hot air is blown on it, or the processing container is heated to dry the food waste and reduce the weight. It is supposed to do.

[0004]

In the food waste disposer, whether it is a microbial decomposition type or a dry type,
Heat is often used to reduce the amount of food waste. Specifically, heat is used to dry food waste (reduction treatment itself) in a dry-type food waste treatment machine, and habitat of microorganisms that decompose (reduce) food waste in a microbial decomposition-type food waste treatment machine. (Temperature) Used to keep the environment moderate. In general, the heat required in the food waste disposer is supplied by a built-in heat source device. As this heat source device, if it is a microbial decomposition type food waste processing machine, for example, a heating heater is provided in contact with the processing container to warm the medium, and if it is a dry type food waste processing machine, For example, a heater or the like for heating the air blown into the processing container is provided.

Here, in the above-mentioned incinerator, high temperature combustion gas is generated by incineration of the material to be incinerated. This combustion gas is usually discharged from an exhaust stack protruding upward from the incinerator,
It is general that the heat is released to the atmosphere through a filter or the like, and the heat of combustion gas is often used as waste energy. And among the companies that use the garbage processor,
For example, there are not a few people who have incineration facilities such as garbage disposal sites and various factories. In this case, if the waste heat of the incineration facility can be used as the heat necessary for operating the garbage treatment machine, it will be a great environmental benefit. Can be expected.

The present invention has been made in view of the above matters, and an object thereof is to provide a garbage disposal system and a garbage disposal which are more environmentally friendly by effectively utilizing waste energy. Especially.

[0007]

An intake pipe line that guides the combustion gas or the atmosphere heated by the combustion gas, and heat of intake air from the intake pipe line,
A food waste processing machine used for reducing the amount of food waste put into the processing container.

In the present invention, the waste heat of the combustion gas of the incinerator is effectively used as the heat energy required for operating the food waste disposer. For example, in the case of a microbial decomposition type garbage processor, the intake air (atmosphere) supplied to the inside of the processing container in order to supply fresh oxygen to the microorganisms in the processing medium must be heated in advance with a heat exchanger. As a result, the habitat environment (temperature environment) of the microorganism can be appropriately maintained. In the present invention, the intake gas (atmosphere) which is the low temperature side fluid can be heated by using the combustion gas as the high temperature side fluid in the heat exchanger.

Further, when heat is applied to the processing medium, in addition to the above-described structure in which heated warm intake air (atmosphere) is directly fed into the processing container, for example, the outer peripheral portion of the processing container is heated by the intake air and is passed through the processing container. It is also conceivable to heat the processing medium inside the heating unit. Moreover, in this case, since the intake air to the outside of the processing container does not come into contact with the microorganisms, the combustion gas may be directly introduced as the intake air to the outer peripheral portion of the processing container. Of course, the outer peripheral portion of the processing container may be heated by the atmosphere that has exchanged heat with the combustion gas as described above.

Further, in the case of a dry type food waste processing machine, it is sufficient to simply dry the food waste in the processing container. Therefore, it is necessary to utilize the combustion gas and the heat of the atmosphere heated by this combustion gas. By drying, the food waste can be reduced without using a heater or a blower. In this case, the combustion gas or the atmosphere heated by the combustion gas may be introduced into the processing container, and may be blown directly to the garbage to be dried. Of course, the combustion gas or the atmosphere heated by the combustion gas may be introduced to the outer peripheral portion of the processing container to heat the processing container to dry the food waste.

However, in the above, the combustion gas and the atmosphere (that is, the intake air) heated by the combustion gas become excessively high due to weather conditions, regional conditions, etc., the treatment medium is excessively heated, and the garbage is burned. It cannot be said that the phenomenon that the garbage disposal machine itself is not loaded or the garbage processing machine itself is burdened. As a measure against such a case, it is preferable to provide a temperature adjusting means in the intake pipe line to the food waste processing machine to adjust the temperature of the intake air.

As described above, according to the present invention, the combustion gas from the incinerator, which is normally released to the atmosphere as waste heat (waste energy), is effectively used as the heat source necessary for operating the food waste disposer. can do.

In the case of carrying out food waste treatment, first, a predetermined operation is performed on the operation panel 9 to open the feeding lid 6 and to put the food waste to be subjected to fermentation decomposition treatment through the feeding port 7 (see FIG. 6) as a processing medium. Is placed in the processing container 10 containing At this time, the worker puts the garbage to be thrown in into the lift container of the throwing lift device (see FIG. 12), and performs a predetermined operation on the operation panel 9.

At the same time, the gas or the like generated by the decomposition processing of the garbage is exhausted to the outside of the processing container 10 to ventilate the inside of the processing container 10. At this time, the control device 32

The operation and effect of this embodiment described above will be sequentially described below. (1) Environmental consideration by effective use of waste energy In the present embodiment, the intake air in the food waste disposer 400 is previously used by utilizing the combustion gas of the incinerator 100 that has been conventionally released to the atmosphere as waste energy. It is heating. As a result, the heater 4 in the food waste processing machine 400 is
2. The operation of each heat source device such as the exhaust heater 51 can be suppressed as much as possible. That is, in the food waste disposer 400 of the present embodiment, the heat required for operation is mainly generated in the incinerator 10.
The built-in heat source device is used supplementarily by acquiring from 0 combustion gas. For example, the built-in heat source device is used when the temperature of the intake air cannot be sufficiently secured mainly due to the weather conditions and the operating condition of the incinerator 100. However, even in this case,
Energy consumption can be suppressed as much as possible because the control device 32 is configured to be appropriately controlled based on the detection result of each temperature sensor. Further, in the control by the control device 32, first, by programming the control of the variable heat exchanger 300 to have the highest priority, it is possible to further reduce the energy consumption of the food waste processing machine 400. As described above, according to the present embodiment, it is possible to effectively use the energy that is not used and to save energy of the raw garbage processing machine 400, and to further consider the environment. Can be performed.

(2) Energy Cycle In the microbial decomposition type food waste disposer, the processing medium is not permanently usable, and the disinfection process of food waste is usually carried out daily as described above. Over time, the processing medium deteriorates and the desired decomposition processing capability cannot be obtained. In this case, it is necessary to replace part (or all) of the processing medium regularly (or as needed). The treatment medium containing the residue taken out from the treatment container is usually transported to a compost center where it is composted and reused. However, there are many cases where the capacity of the compost center is not always sufficient, and the part that cannot be accepted by the compost center is often incinerated.

In this case, since the food waste processing system of the present embodiment is provided with the food waste processing machine 400 and the incinerator 100, the used processing medium can be converted into energy again in the system. it can. That is, since the food waste disposer 400 uses the combustion gas of the incinerator 100 as a heat source, the combustion heat generated by incineration of the processing medium is effectively reduced again as the heat source of the food disposer 400.
As described above, in the present embodiment, the treatment medium and the residue can be easily treated, and the energy generated thereby can be effectively used again. In this way, energy cycle can be realized.

(3) Improvement of treatment efficiency of used treatment medium Normally, when incinerating the used treatment medium, the treatment medium taken out from the food waste disposer is transported to the incineration facility by a truck or the like. Such transportation of the processing medium requires time, labor and cost and is not an efficient operation. On the other hand, in the present embodiment, since the used processing medium can be processed in the system as described above, the time, labor and cost required for this work can be reduced.

In the present embodiment, the combustion gas is directly applied to dry the food waste. However, for example, the combustion gas is guided to the outer peripheral side of the processing container 402 to form the processing container 4.
A configuration in which 02 is heated to evaporate the water content of food waste may be considered. The technical idea of the present invention is that the incinerator 100
The waste heat is used to reduce the amount of food waste, and the waste heat does not have to be limited to the configurations of the embodiments described above, and various other modifications are possible. Hereinafter, such a configuration example will be sequentially described with reference to FIGS. 19 to 23.

19 (a) to 19 (c) are conceptual diagrams showing a schematic configuration of a modified example of the food waste processing system of the present invention. However, these FIG. 19 (a) to FIG. 19 (c)
In FIG. 7, the same parts as those in the previous figures are designated by the same reference numerals and the description thereof will be omitted. In each of the modified examples shown in FIGS. 19 (a) to 19 (c), the atmosphere is heated by the combustion gas in the heat exchanger 200, and the temperature is adjusted via the variable heat exchanger 300. It leads to the garbage processor 400X.
Then, in the modified example of FIG. 19A, the warm atmosphere from the intake conduit 203 is guided into the processing container 10X, and FIG.
In the modified example, the warm atmosphere from the intake pipe 203 is guided to the outside of the processing container 10X. In addition, FIG.
In the modified example of (c), the atmosphere from the intake pipe 203 is guided to both inside and outside the processing container 10X.

In each of the modified examples shown in FIGS. 19 (a) to 19 (c), the clean air is heated to dispose of the garbage processing machine 400.
Since the configuration is such that it leads to X, the garbage processing machine 400X can be applied to either a microbial decomposition type or a dry type. That is, when a microbial decomposition type is used as the food waste disposer 400X, the warm atmosphere supplied into the processing container 10X supplies oxygen to the microorganisms and directly gives heat to the treatment medium to cause the temperature of the microorganisms to rise. The environment is made suitable, and the atmosphere introduced outside the processing container 10X heats the processing container 10X to indirectly give heat to the processing medium. On the other hand, when a dry type is used as the food waste processing machine 400X, the warm atmosphere supplied into the processing container 10X directly dries the food waste, and the atmosphere introduced outside the processing container 10X is The processing container 10X is heated to indirectly heat and dry the food waste.

The modified examples shown in FIGS. 19 (a) and 19 (c) are systems having substantially the same concept as the garbage processing system shown in FIGS. 1 and 15, respectively. In addition, the present invention is not limited to the microbial decomposition type food waste processing machine, and other types of food waste processing machines such as a dry type may be used. Further, the variable heat exchanger 300 may be a simple heat exchanger, or conversely, the heat exchanger 200 may have a temperature adjusting function. In addition, depending on the situation, it is of course possible to provide a larger number of heat exchangers in multiple stages.

20 (a) to 20 (c) are conceptual diagrams showing a schematic configuration of another modified example of the food waste processing system of the present invention. However, these FIG. 20 (a) to FIG.
In (c), the same parts as those in the previous drawings are denoted by the same reference numerals and the description thereof will be omitted. 20A to 20.
Each of the modified examples shown in (c) also introduces the atmosphere into the food waste disposer 400X, but the variable heat exchanger 300 is omitted. That is, the atmosphere is heated by the combustion gas in the heat exchanger 200, and the atmosphere is directly guided to the food waste processing machine 400X. Then, the modified example of FIG. 20 (a) guides the warm atmosphere from the intake conduit 203 into the processing container 10X, and the modified example of FIG. 20 (b) processes the warm atmosphere from the intake conduit 203. It is designed to lead to the outside of the container 10X. Also,
In the modified example of FIG. 20C, the atmosphere from the intake conduit 203 is guided both inside and outside the processing container 10X.

In each of the modified examples shown in FIGS. 20 (a) to 20 (c), the clean air is heated to treat the garbage processing machine 400.
Since the configuration is such that it leads to X, the garbage processing machine 400X can be applied to either a microbial decomposition type or a dry type. In such a case where strict control of the intake air temperature is not required, the heat is not provided in multiple stages and the atmosphere is introduced into the food waste disposer 400X via the single heat exchanger 200 as described above. The configuration is sufficient and the same effect can be obtained. In each of the modified examples shown in FIGS. 20A to 20C, the heat exchanger 200 may of course have a temperature adjusting function.

21 (a) to 21 (c) are conceptual diagrams showing a schematic configuration of still another modification of the food waste processing system of the present invention. However, these FIG. 21 (a) to FIG.
In (c), the same parts as those in the previous drawings are denoted by the same reference numerals and the description thereof will be omitted. 21 (a) to 21.
In each of the modified examples shown in (c), the temperature is adjusted via the variable heat exchanger 300, and then the combustion gas is directly fed to the food waste disposer 40.
It leads to 0X. The modification of FIG. 21 (a) guides the combustion gas from the intake pipe 203 into the processing container 10X, and the modification of FIG. 21 (b) guides the combustion gas from the intake pipe 203 to the processing container 10X. It is designed to guide you outside. Further, in the modified example of FIG. 21C, the combustion gas from the intake conduit 203 is guided to both inside and outside of the processing container 10X.

21 (a) to 21 (c), since the combustion gas is guided to the food waste disposer 400X, the modifications shown in FIGS. 21 (a) and 21 (c) are performed. As in the example, when the combustion gas is introduced into the processing container 10X, it is not desirable to apply it to a microbial decomposition type garbage treatment machine, and therefore, a drying type garbage treatment machine is used as the garbage treatment machine 400X. . Since the modified example of FIG. 21 (b) does not guide the combustion gas into the processing container 10X, both dry type and microbial decomposing type garbage disposals can be used as the garbage disposal 400X. . Note that FIG.
The modification of 1 (a) has the same concept as that of the embodiment shown in FIG. 16, and the modification of FIG. 21 (b) has the same concept as that of the embodiment shown in FIG. Is the concept of. However, as described above, the modified example of FIG. 21 (b) is not limited to the microbial decomposition type as the garbage processing machine 400X, and can be applied to a dry type garbage processing machine. Further, the variable heat exchanger 300 may be a simple heat exchanger, or may have a configuration in which a heat exchanger (or a variable heat exchanger) is added, depending on the required ability to adjust the intake air temperature.

22 (a) to 22 (c) are conceptual diagrams showing the schematic construction of still another modification of the food waste processing system of the present invention. However, these FIG. 22 (a) to FIG.
In (c), the same parts as those in the previous drawings are denoted by the same reference numerals and the description thereof will be omitted. 22A to 22.
In each of the modified examples shown in (c), the combustion gas is directly guided to the food waste disposer 400X without passing through a heat exchanger. Then, the modification example of FIG. 22A guides the combustion gas from the intake pipe line 203 into the processing container 10X, and the modification example of FIG. 22B shows the combustion gas from the intake pipe line 203 of the processing container 10X.
It is designed to guide you outside. Further, in the modified example of FIG. 22C, the combustion gas from the intake pipe line 203 is treated by the processing container 10X.
It is designed to lead to both inside and outside.

22 (a) to 22 (c), since the combustion gas is guided to the food waste disposer 400X also in the modifications shown in FIGS. 22 (a) and 22 (c). As in the example, when the combustion gas is introduced into the processing container 10X, it is not desirable to apply it to a microbial decomposition type food waste processing machine, and a dry food processing machine is used as the food processing machine 400X. The modified example of FIG. 22B is a processing container 10X.
Since it does not guide the combustion gas into the inside, the garbage processor 4
As 00X, both dry type and microbial decomposing type garbage processing machines can be used. For example, in an operation in a cold region or the like, even if the intake air temperature is not adjusted by the heat exchanger (or the variable heat exchanger), it is possible to use the modifications shown in FIGS. 22 (a) to 22 (c). In some cases, a similar configuration may be sufficient, and the same effect can be obtained.

23 (a) and 23 (b) are conceptual diagrams showing a schematic configuration of still another modification of the food waste processing system of the present invention. However, these FIG. 23 (a) and FIG.
In (b), the same parts as those in the previous drawings are designated by the same reference numerals and the description thereof will be omitted. For example, when the food waste disposer is operated in a cold region or a region with snow, the intake air temperature may be below freezing. As a measure in such a case, there is a case where a garbage processor is installed inside the building. These Figure 2
Both of the modified examples shown in FIG. 3A and FIG. 23B are applied when the food waste disposer 400X is installed in the building 500.

In the modification of FIGS. 23 (a) and 23 (b), the atmosphere heated by the combustion gas in the heat exchanger 200 is introduced into the building 500 to keep the room temperature in the building 500 warm. is there. And the garbage processor 400X
The warm atmosphere in the building 500 is introduced into the interior as intake air. Of course, for the garbage processor 400X,
A microbial decomposition type is also applicable. Also, FIG.
In the modified example of (a), the temperature of the atmosphere warmed through the heat exchanger 200 is adjusted by the variable heat exchanger 300 and then introduced into the building 500, whereas the modified example of FIG. In the modified example, the atmosphere heated in the heat exchanger 200 is directly introduced into the building 500. Of course, these FIG.
The configurations of both the modification examples of (a) and FIG. 23 (b) can be selectively and appropriately selected according to the required temperature adjusting ability of the intake air. Further, in this case, the heat exchanger 200 may be provided with a temperature adjusting function, and the variable heat exchanger 3 in FIG.
00 may be replaced with a simple heat exchanger. Further, if it is necessary to further lower the intake air temperature depending on the distance between the incinerator 100 and the building 500 and the scale of the incinerator 100, a heat exchanger (or a variable heat exchanger) may be added. As described above, similar effects can be obtained in each of the modified examples described with reference to FIGS. 19 to 23.

In each of the above-described embodiments and modifications, the variable heat exchanger 300 is provided as a device separate from the food waste disposer, but it may be incorporated in the food waste disposer. For example, in FIG. 9, a flow rate adjusting valve may be provided near the intake port 46, and the heat exchanger 47 may be configured as a variable heat exchanger with variable heat exchange efficiency. Although the intake ducts 203 and 203A in each of the embodiments are not provided with a blower or the like, in the case where the exhaust fan in the food waste processing machine is insufficient, of course, for example, a blower fan is provided in the middle of the intake duct. May be provided.

Further, in the above, the basic constitution is not limited to those of the respective garbage treatment machines 400, 400A to 400C, 400X described above, whether it is a microbial decomposition type or a dry type, and the technical idea of the present invention can be applied. Without departing from the present invention, the present invention is applicable to various other types of food waste disposal machines. For example, the food waste disposer 4 described in the embodiment
No. 00, it is not always necessary to provide a deodorizing unit (deodorizing device) or the like, and a dry type food waste disposer 400
The present invention can be applied to both the C type and the type in which the stirring means 406 is omitted. In addition, the deodorizing device, etc.
It is also possible to have a different configuration from the processor main body.

Further, in the above, the example in which the waste heat of the incineration facility is used as the heat source has been described, but it may be difficult for homes, restaurants, etc. to take in the combustion heat of the incinerator. However, even households, restaurants and the like can use, for example, exhaust air from a water heater or a kitchen duct. That is, the heat source used for the food waste disposer is not necessarily limited to the combustion gas from the incinerator, and various other waste energy can be used for the heat (or part of it) required for the food waste disposer. It can be considered to be used as a heat source for obtaining.
