2. Description of the Related Art Conventionally, hotels, inns, restaurants,
In the cafeteria, hospital catering, food factories, golf courses, catering centers, supermarkets, fishery associations, public facilities, etc. There have been fermentation and decomposition products that convert them into useful processed products, and attempt to recycle garbage resources. Hereinafter, an outline of the configuration and functions of this type of conventional garbage decomposition apparatus will be described with reference to the accompanying drawings.

FIG. 8 is a front transparent view showing a schematic configuration of a conventional garbage decomposition processing apparatus.

As shown in FIG. 1, this conventional garbage decomposition processing apparatus α comprises a processing apparatus main body (b) having a decomposition processing tank (a) installed therein and a garbage to be subjected to fermentation decomposition processing. The garbage inlet (c) for charging the garbage into the decomposition tank (b) and the rotating spindle (d) horizontally laid down in the decomposition tank (b) are installed from the center to both ends. A stirring screw (e) formed in a spiral shape opposite to each other, and a drive motor (f) connected to a rotating main shaft (d) to rotationally drive the stirring screw (e);
It is opened at the lower part of the processing equipment main body (b) and has a product outlet (g) for taking out the processed product generated by the fermentation decomposition processing, and the processing equipment main body (b) for blowing and heating the inside of the decomposition processing tank (b). And (b) a heating device (f) laid in the ceiling room (h).

In the figures, (nu) is a suction port, (lu) is a fume port, (ヲ) is a hot air circulation duct, (wa) is a combustion chamber,
(F) is an exhaust chimney.

In order to actually perform the decomposition processing of garbage by the conventional garbage decomposition processing apparatus α having the above-described configuration, first, the garbage to be subjected to the decomposition processing from the garbage input port (c). Put the garbage into the decomposition tank (a). At this time, since the garbage usually has a high water content of about 80% by weight, in order to reduce the water content and maintain an environment suitable for the growth of aerobic fermentative bacteria, for example, dry organic matter is used. And a required amount of a water conditioner consisting of

[0007] Next, after the required amount of aerobic fermentation bacteria is put into the decomposition treatment tank (a), the drive motor (f) is driven to rotate the stirring screw (e), and the put garbage and water While continuously stirring and mixing the regulator and the aerobic fermentation bacterium, the mixture is maintained at a constant temperature such that the internal temperature thereof is about 80 ° C. by blowing hot air blown from a blowing device (h).

At this time, since the environment suitable for the growth of the aerobic fermentation bacteria is maintained by the addition of the water regulator and the heating of the mixture, the added aerobic fermentation bacteria grow rapidly and the garbage is removed. The fermentation decomposition process is continuously promoted.

[0009] The types of decomposing action of organic substances such as garbage as mentioned above include assimilation action to supply nutrients to microorganisms and synthesis of new nuclear substances, and decomposition of organic substances into low molecular weight substances by fermentation and the like. Although the conventional garbage decomposition treatment device α uses a plurality of types of aerobic fermenters that perform aerobic high-temperature fermentation, the above-described catabolism and catabolism are well-balanced. I'm trying to drip.

[0010] From this, garbage is converted into a useful treatment product by fermentation decomposition treatment, and the treatment product is
It could be reused directly as fertilizer or livestock feed, or mixed with other fertilizers or livestock feed.

As a result, there was a problem that the treated product itself was treated as garbage again. I was

In order to avoid the above-mentioned problems, there is a method of eliminating an object to be treated such as garbage or reducing the volume without assuming that the treated product is recycled. For example,
A good example is a method of incinerating garbage and other materials to be incinerated using an incinerator, reducing the volume of the waste to make it harmless, and then burying it.

However, in recent years, the effects of harmful chemical substances such as dioxins generated by incineration on humans and the environment have been a problem especially in small-scale incinerators. It is difficult for relatively small establishments, such as restaurants, to install incinerators and incinerate waste such as garbage.

Second, in the conventional garbage decomposing / treating apparatus α, the fermentation / decomposition of garbage is carried out by using aerobic fermentation bacteria. Various kinds of organic gases having properties have been generated, and this has diffused out of the apparatus through the exhaust chimney, causing a problem of generating an unpleasant odor around the apparatus.

Here, the main objects to be solved by the present invention are as follows.

That is, a first object of the present invention is to provide an extinguishing-type garbage decomposing method capable of decomposing and decomposing garbage and generating no harmful chemical substances during the decomposition process. No device is provided.

The extinguishing-type garbage decomposer β is basically constructed as described above, and is further provided with the following equipment in order to enhance its safety and functionality.

That is, in order to enhance operational safety during operation of the extinction-type garbage decomposing / disposal apparatus β, one with an adjuster is used as the installation leg 28 thereof. The operation control unit C includes a door switch (not shown) for detecting the opening and closing of the charging lid 4 at a key point thereof.

The heat retention of the mixture in the decomposition treatment tank 1 during the decomposition treatment is enhanced, and the gas burner 1
1, the consumption of the combustible gas used is minimized.

(First Method Example) Next, a first method example applied to the elimination-type garbage decomposition processing apparatus β of the first apparatus example configured as described above will be described.

First, in the first example of the method, when performing the decomposition treatment of garbage, a plurality of types of microorganisms including a bacterial species performing aerobic high-temperature fermentation and a bacterial species performing anaerobic high-temperature fermentation are used.
Aerobic bacteria, anaerobic bacteria, facultative anaerobic bacteria, actinomycetes, and filamentous fungi are used in combination. At the time of its actual use, in consideration of its handleability, for example, a granular base material obtained by adhering a culture of a plurality of types of microorganisms to the surface may be applied (for example, the granular base material may be “ Biochip "
Etc.).

The procedure for actually decomposing the garbage is as follows. First, the charging lid 4 is opened, and the garbage of the object to be processed and an appropriate amount of a plurality of microorganisms (granular base materials) are mixed in the garbage charging port 2. Into the decomposition tank 1. At this time, it is desirable to put the garbage to be subjected to the decomposition treatment after removing the water as much as possible, and when the water content is large, add an appropriate amount of a water regulator together. Is also good.

Next, the twin timer 2 of the operation control panel C1
4 to set the rotation / non-rotation time of the stirring screw 6 in advance, and the automatic temperature controller 25 to operate the plurality of microorganisms of the garbage thrown into the decomposition treatment tank 1. Predetermine the optimum temperature at which decomposition can be promoted.

The preset values of the twin timer 24 and the automatic temperature controller 25 can be arbitrarily set. However, in actual operation, for example, the operation (rotation) of the twin timer 24 is, in principle, 10 (rotation). Minute and stop (non-rotation) may be set to 20 minutes, and the temperature of the automatic temperature controller 25 may be set to 50 ° C. in principle.

Next, when the operation switch 26 is turned on, the screw rotation control means of the operation control device C causes
The drive motor 23 and the speed reducer 23a are started, and the stirring screw 6 is controlled to rotate integrally with the rotating main shaft 6a, so that the garbage and a plurality of kinds of microorganisms are stirred in a spiral manner in the decomposition tank 1. Mixed. At the same time, the spark ignition solenoid valve 21b in the jet heating device B1 is first opened by the hot air temperature control means of the operation control device C, and the spark ignition gas opened by this is supplied to the spark ignition gas pipe 20b.
Then, the ignition is ignited by facing the gas burner 11 port, and then the combustion solenoid valve is opened, whereby the opened combustion gas is supplied to the gas burner 11 port via the combustion gas pipe 20a to wait for combustion. Ignition is performed by the igniting spark. Further, power is also supplied to the fan motor 16 and the blower fan 10 starts blowing.

As a result, the hot air obtained by the gas burner 11 is forcibly blown by the blower fan 10 from the blowing port 8 of the blowing device B1 into the decomposition treatment tank 1 constituting a substantially closed space. The hot air generated by the blast is blown to the mixture, and the air in the decomposition tank 1 is sucked by the blower fan 11 from the suction port 7 of the blast device B1 (circulation return air (the air intake of the combustion chamber 12). (Including a small amount of combustion air taken in from the inlet 12a) is reheated by the gas burner 11 to obtain heated circulation return air.

During this time, the stirring screw 6 rotates the mixture in a spiral manner while rotating at a low speed, and mixes air (hot air) into the inside. That is, garbage and a plurality of types of microorganisms are continuously heated by hot air while being stirred and mixed, and in combination with this, the overall temperature of the mixture gradually increases due to fermentation heat accompanying the decomposition of garbage. Go.

At this time, the internal temperature of the mixture is detected in real time by a temperature sensor inserted at a predetermined position in the decomposition processing tank 1, and based on the detected value, the automatic temperature controller 2
The supply amount of the combustion gas to the gas burner 11 of the jet heating device B1 is controlled so that the set temperature of the combustion solenoid valve 21 is maintained.
a, and the air volume of the hot air blown to the mixture is also adjusted by the air volume adjustment damper 22, so that the internal temperature of the mixture is constantly set to the optimum temperature (50 ° C. in principle setting). ) Is kept at a constant temperature.

As a result, the decomposition of garbage by the microorganisms of the species performing the aerobic high-temperature fermentation is promoted, and the aerobic high-temperature fermentation process is carried out for a predetermined time (in principle, the twin timer 24). (10 minutes with proper setting).

Next, when the time set in advance by the twin timer 24 elapses, the stirring screw 6 is controlled to the non-rotation state by the screw rotation control means of the operation control device C, and the operation is continued as long as the constant temperature state is maintained. By the hot air temperature control means of the control device C, the combustion electromagnetic valve 21a in the blast device B1 is closed, and the gas burner 11 remains in an extinguishing state leaving an ignition (the ignition electromagnetic valve 21b is operated in the next time). The valve is kept open for ignition). The fan motor 16
The power supplied to the fan is also shut off, and the blower fan 10 stops blowing.

When the temperature drops and the temperature cannot be maintained, the combustion solenoid valve 21a is opened, and the supplied combustion gas is ignited and burned by an ignition so that the gas burner 11 is operated. Energize the motor 11 and blow fan 1
The constant temperature control for starting the blowing of 0a is measured. O like above
A constant temperature steady state is achieved by N-OFF control.

As a result, the stirring of the mixture in the decomposition treatment tank 1 is completely stopped, and the new mixture of air (hot air) into the mixture is stopped. And
Along with this, the decomposition of garbage by microorganisms of the species that perform anaerobic high-temperature fermentation is promoted, and this anaerobic high-temperature fermentation process is carried out for a time set in advance by the aforementioned twin timer 24 (in principle, setting). 20 minutes).

As described above, a plurality of types of microorganisms including aerobic bacteria, anaerobic bacteria, facultative anaerobic bacteria, actinomycetes, and filamentous fungi are used in combination to conduct an aerobic high-temperature fermentation process. By alternately and periodically repeating the anaerobic high-temperature fermentation process, the input garbage is almost completely converted to water (steam) and carbon dioxide due to the complementary synergistic action of both species contained in the plurality of microorganisms. Will be decomposed into

The time required for the decomposition of garbage is as follows:
Depending on the contents, for example, meat and vegetable scraps are decomposed in about 5 to 6 hours, and most of the hard-to-decompose vegetable cores, shrimp, crab shells, or fish are decomposed in one day. You.

On the other hand, in the decomposition treatment tank 1, the moisture originally contained in the inputted garbage and the moisture generated by the decomposition treatment of the garbage are both converted into steam by heating, and the outside air of the combustion chamber 12 is heated. With the pressure of the combustion air taken in from the intake port 12a, the air evaporates to the outside through the exhaust port 15 by natural ventilation (gas phase discharge). Similarly, the carbon dioxide generated by the decomposition also diffuses to the outside through the exhaust port 15 by natural ventilation with the pressure of the combustion air described above (gas phase discharge).

At this time, various organic gases having an odor generated in the course of the fermentation decomposition treatment of the garbage are to diffuse out of the decomposition treatment tank 1 through the exhaust port 15 together with water vapor and carbon dioxide. These organic gases are
After being heated to, for example, 250 to 300 ° C. by heat exchange radiant heat generated from the exhaust gas heating fin tube group 17 provided on the exhaust path of the exhaust duct 16, the heat is introduced into the deodorizing catalyst layer 18 immediately above, The deodorizing catalyst layer 18 is designed to perform a deodorizing process. (The heat source of the exhaust gas heating fin tube group 17 includes, in addition to the illustrated gas burner 11, another heat source independent of the gas burner 11 (for example, an electric heat source). A heater or the like).

More specifically, the deodorizing treatment in the deodorizing catalyst layer 18 is an elimination odor accompanied by contact with a predetermined deodorizing catalyst in a high-temperature environment. What is done can be applied. As a result of this deodorizing treatment, most of the organic gas is removed from the deodorizing catalyst layer 18, and the composition of the exhaust gas exhausted from the exhaust pipe 19 becomes substantially water (water vapor) and a carbon dioxide device. As a result, it is possible to prevent the generation of an off-flavor in the surroundings.

During the execution of the anaerobic high temperature fermentation process, the exhaust gas is heated by the exhaust gas heating fin tube group 17 because the blasting device B1 is stopped as long as the temperature is kept constant. However, at this time, the circulation of hot air in the hot air circulation duct 9 and the decomposition tank 1 is also stopped,
Since the combustion air cannot be taken in from the outside air inlet 12a of the combustion chamber 12 and natural ventilation of the exhaust gas is suppressed, it is also possible to prevent the surroundings from emitting an offensive odor.

By the above-mentioned garbage decomposition treatment, the garbage is almost decomposed into water vapor and carbon dioxide, but a small amount of residue remaining in the decomposition tank 1 contains a plurality of microorganisms. Once the operation is started by leaving it as a base material and providing it for long-term repeated use to propagate, basically, additional garbage is added to the decomposition tank 1 to produce garbage. It is possible to continuously carry out the decomposition treatment of the microorganisms (if necessary, the microorganisms may be appropriately supplemented, for example, about once every 10 days).

It is sufficient to discharge and discard the residue from the outlet 3 at the lower part of the decomposition treatment tank 1 at the time of maintenance, for example, about once a year.

On the ventilation path of the hot-air circulation duct 9, an important point between the upstream area of the blower fan 10 and the downstream area of the blast device B1 is an external air intake for taking in external air from the outside. An inlet valve 33 is attached (details will be described later).

Further, in the destructible garbage decomposition apparatus γ according to the second apparatus example, the product discharging / deodorizing apparatus B2
Also has characteristic elements different from those of the first device example.

That is, the product discharging / deodorizing device B2 is
A steam liquefaction device 34 installed near the suction port 7 on the ventilation path of the hot air circulation duct 9 for cooling and liquefying the steam contained in the circulating return air and allowing the liquefied water obtained thereby to drop naturally; A drain pan 3 installed in an area within the decomposition treatment tank 1 located immediately below the device 34 and receiving water naturally dropped from the steam liquefaction device 34.
5 and the water received by the drain pan 35 is drained and drained to the outside world through the drain port 35a, and the exhaust gas containing carbon dioxide and organic gas present in the decomposition treatment tank 1 is taken into the above-described outside air intake. A drain pipe 36 forcibly exhausting to the outside world with the intake pressure of the outside air from the valve 33;
By temporarily storing the water naturally drained through the drain pipe 36, the exhaust gas forcedly exhausted through the drain pipe 36 is released as bubbles into the once-stored water and brought into contact with the water. ,
A water storage deodorization tank 37 for deodorizing the organic gas contained in the exhaust gas by dissolving it in water is configured.

The steam liquefaction device 34 includes a dehumidifying fin 38a of a compressor 38 for circulating a refrigerant for liquefying the steam contained in the circulation return air. The operation control panel C1 of the operation control device C is provided with a compressor switch 39.

Further, the hot air temperature control means in the mixture constant temperature holding means of the operation control device C is provided with a power supply control means for controlling the power supply to the electric heater 31. By combining a temperature sensor such as a thermostat or a thermistor applied in the extinguishing-type garbage decomposition processing apparatus β of the apparatus example with a predetermined electric circuit (not shown), it can be used as it is.

Next, the details of the water storage / deodorization tank 37 constituting the product discharge / deodorization apparatus B2 will be described.

FIG. 7 is a cross-sectional view showing the principle configuration of the water storage deodorizing tank 37 applied to the extinction-type garbage decomposition apparatus γ according to the second apparatus example.

7 is provided with a mesh member 37a for reducing the size of foam to promote the melting of the organic gas contained in the bubble exhaust gas, which is floated in the water once stored, into water. An overflow pipe 37 for draining water once the stored water reaches a prescribed water level.
b.

The extinguishing garbage decomposing / processing apparatus γ according to the second example of the apparatus is configured as described above, and the other parts that are not described are the same as those of the first example. It is the same as or equal to that of β.

(Second Method Example) Next, a second method example applied to the extinction-type garbage decomposition processing apparatus β of the second apparatus example configured as described above will be described.

In the second example of the method, the steam in the circulating return air obtained by sucking the air in the decomposition treatment tank 1 from the suction port 7 of the jet heating device B1 by the blower fan 10 is supplied to the operation control board C
The water is condensed and cooled by the dehumidifying fins 38a (steam liquefaction device 34) of the compressor 38, which is driven by operating the compressor switch 39, whereby water condensed on the surface of the dehumidifying fins 38a drops naturally to the drain pan 35. After being received, it is then drained and drained to the storage deodorizing tank 37 through the drain port 35a and the drain pipe 36 (liquid phase discharge).

The exhaust gas containing carbon dioxide and organic gas present in the circulation return air follows the same path as the above-mentioned naturally dropped water while passing through the outside air intake valve 33.
, And is forcibly evacuated to the stored water deodorizing tank 37 as it is with the outside air intake pressure (gas phase discharge).

At this time, the circulation return air is supplied to the steam liquefier 3
Due to the action of the large number of dehumidifying fins 38a existing in the hot air circulation duct 4, the hot air is somewhat lost when it reaches deep inside the hot air circulation duct 9. Therefore, in the extinction-type garbage decomposition apparatus γ according to the second apparatus example, the outside air intake valve 33 attached to an area upstream of the area in which the blower fan 10 is installed communicates constantly from the outside world. "Is adopted. This outside air is also used as a pressure for forcibly exhausting the exhaust gas, as described above.

By the action of water, it is made into fine bubbles when passing through the water once stored by the downflow drainage (such as tap water previously stored at the beginning of operation), and the organic matter contained in the exhaust gas Melting of the gas into water is promoted. As a result, most of the organic gas is removed by melting and deodorizing with contact with water, and the composition of the exhaust gas released from the surface of the once stored water to the outside becomes almost carbon dioxide, As a result, it is possible to prevent the surrounding odor from being emitted.

The embodiments of the present invention have been described with reference to the first device example and the corresponding first method example, and the second device example and the corresponding second method example. The present invention is not necessarily limited to the above-described means and methods, but can be appropriately changed and implemented within the scope of achieving the object of the present invention and having the effects described below.
