Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus for decomposing garbage by so-called microorganisms such as bacteria, filamentous fungi, and actinomycetes existing in the soil.

[0002]

2. Description of the Related Art Various types of garbage disposal apparatuses have been proposed in the past, but in each case, the decomposition time of garbage is long, and the garbage has reached a level that can sufficiently cope with daily generated garbage. Not in. In other words, garbage is generated not only at home, but also in restaurants, lunch centers, and other business shops, where a large amount of garbage is generated every day.
It is desirable that the garbage generated on that day be disposed of within that day (at the latest until the next day), but at this time it takes several days to decompose, and there is still a sense of practical use, The challenge is how to increase the processing time and reduce the processing time to several hours. In general, the decomposition treatment capacity is governed by the amount of microorganisms adhered per unit volume of environmental garbage, in which the potential microorganisms of the microorganisms themselves are likely to work.
Microorganisms were collected from various soils with different properties and temperature conditions were changed.Or, garbage was finely crushed by a crusher to increase the amount of microorganisms attached. Was obtained but far from practical.

[0003]

Means for Solving the Problems The present inventor has found that, compared to temperate forests, tropical forests produce more organic matter and reduce organic matter (vegetable organic matter such as defoliated leaves, litters, residual roots, etc.) In spite of the large amount of animal organic matter (insects and small animal carcasses), the amount of decomposition by microorganisms is large and the amount of accumulated organic matter in the soil is extremely small. became. Microorganisms contained in soils of the tropics have many thermophilic microorganisms, and their decomposition ability is much higher than that of normal temperature microorganisms. In addition, the thermophilic microorganisms are in a normal temperature environment (when the bed temperature is 20 ° C).
(30 ° C-30 ° C), the function is poor, it takes a long time to decompose garbage as organic matter, and if the bacterial bed temperature is artificially preheated to 40 ° C-50 ° C, the function becomes active, When
The heat generated by itself increases the temperature of the bacterial bed rapidly to the optimum decomposition temperature of 60 ° C to 90 ° C, and the decomposition capacity increases. When the state is left, the temperature of the bacterial bed exceeds 90 ° C due to the heat generated by microorganisms. Although it rises to some extent, it reaches a plateau from around this point, and thereafter the temperature of the bacterial bed gradually decreases. It is considered that when the temperature of the microbial bed exceeds the optimum temperature and rises beyond a certain limit, the growth activity of the microorganisms is slowed down, and finally the temperature is lowered by death and the degradation ability is reduced. In addition, if the preheating temperature of the bacterial bed is set to the optimum temperature, the amount of decomposition of garbage at the initial stage of input can be increased, but the improvement margin is small, and conversely, the bacterial bed temperature exceeds the optimum temperature and the capacity decreases due to the death of microorganisms The preheating of the microbial bed should preferably be set slightly lower than the optimal decomposition temperature, since this would require special equipment for cooling as well as the cooling. In addition, this group of thermophilic microorganisms has a high decomposition ability in an aerobic environment, and in an oxygen-deficient state and in an anaerobic environment, not only the ability is reduced, but also an odor is easily generated, The process requires a suitable air supply. Meanwhile,
If air is supplied unnecessarily, not only does the temperature of the germ bed decrease, so that sufficient decomposition ability cannot be obtained, but also the evaporation of water generated by the decomposition decreases, and as a result, the processing time of garbage becomes longer. Therefore, the supply of air to the processing chamber needs to be appropriately controlled so as to keep the temperature of the bacterial bed high while maintaining the aerobic environment.

[0004]

SUMMARY OF THE INVENTION The present invention has been made based on such new knowledge, and has a garbage processing chamber having therein a bacterial bed carrying a thermophilic microorganism group therein, and a garbage processing chamber introduced into the processing chamber. A stirring means for stirring refuse and the bacterial bed; a preheating means for preheating the bacterial bed in the processing chamber at a temperature lower than the optimum activation temperature of the thermophilic microorganism group; and discharging steam generated in the processing chamber. A garbage disposal apparatus, comprising: a discharge means for supplying air to the outside of the processing chamber; Therefore, according to the present invention, since the ability of the thermophilic microorganisms can be maximized, the processing time of the introduced garbage can be extremely shortened. Also, 60 ° C to 90 ° C
The use of a thermophilic microorganism group having an optimum activation temperature of ° C. kills various germs in garbage, so that the generation of offensive odor and the like can be suppressed. That is, garbage contains a lot of room temperature harmful bacteria, and these harmful bacteria are 60 ° C to 90 ° C.
Since it is extinguished at a temperature of ° C., the safety as a device as well as the suppression of offensive odor is extremely high. According to a second aspect of the present invention, there is provided a garbage disposal apparatus including a control unit capable of arbitrarily controlling the amount of intake and exhaust. Therefore,
According to the present invention, it is possible to arbitrarily adjust the bacterial bed temperature and the moisture in the processing chamber (water generated by decomposition of garbage), that is, the bacterial bed temperature, by controlling the amount of intake and exhaust.
For example, a relatively high temperature state is preferable for hardly decomposable substances such as fibers, and a relatively low temperature may be used for easily decomposable substances such as hydrocarbons and proteins. can do. Further, in this type of processing apparatus, a large amount of water is generated in addition to carbon dioxide gas by the decomposition of garbage, and it is necessary to evaporate such water and quickly discharge it to the atmosphere by exhaust means. However, intake and exhaust have a series of correlations,
Increasing the displacement will result in more intake (and decreasing the displacement will also decrease the intake),
If the amount of exhaust is increased unnecessarily in order to promote the discharge of water, as a result, the temperature of the germ bed decreases due to the introduced intake air, and the efficiency of the microorganism decomposition treatment decreases. Conversely, if the amount of exhaust is too small, the amount of intake air decreases, the temperature of the bacterial bed increases, and the efficiency of decomposition treatment improves. On the other hand, a large amount of generated water is not sufficiently exhausted. As a result, the aerobic condition is broken and the decomposition ability is reduced. Therefore, according to the second aspect of the present invention, since the intake and exhaust can be arbitrarily controlled according to the properties of the garbage and the like, it is extremely efficient. A third aspect of the present invention is a garbage disposal apparatus characterized in that a mode for increasing and decreasing the amount of intake and exhaust air is provided, and the two modes are alternately controlled in the process of treating garbage. Therefore, according to the present invention, the increase and decrease modes of intake and exhaust can be automatically and alternately controlled at regular time intervals, so that the water generated by decomposition can be optimized while maintaining the temperature of the bacterial bed at a high temperature. As a result, the garbage can be efficiently treated. Further, the fourth invention is characterized in that a deodorizing device is provided in the exhaust means, and the intake and exhaust means is controlled so that the pressure in the processing chamber becomes equal to or lower than the atmospheric pressure during the processing of garbage. Garbage processing equipment. According to the fourth aspect, since the offensive odor is surely deodorized by the deodorizing device of the exhaust means and discharged to the atmosphere without flowing out from the entire device in the processing chamber to the outside. Leakage of deodorant odor can be reliably prevented. According to a fifth aspect of the present invention, a fibrous filter member is provided in the duct as an exhaust means extending upward from the outer wall of the main body over substantially the entire region in the longitudinal direction, and moisture condensed in the filter member is collected in the processing chamber. A garbage disposal apparatus provided with a collecting means. According to the fifth aspect, since the moisture in the exhaust gas condenses on the filter surface and the inside of the filter is brought into a high humidity state, the odor in the exhaust gas is taken in by the water droplets, and the deodorizing effect is improved. Conventionally, as this type of deodorizing device, water from a separate water tank or the like is sprayed into the duct using a special spraying device or the like, but this conventional device is complicated and increases the cost. I was In the present invention, it is only necessary to provide a fibrous filter member, and the cost is extremely low. Moreover, since the water droplets that have taken in the odor are surely collected in the processing chamber by the collecting means, it is possible to reliably prevent the odor from flowing out. Also,
According to a sixth aspect of the present invention, the exhaust means includes an upstream duct having one end opened at an upper portion of the processing chamber and extending substantially horizontally inside the main body, and a downstream duct protruding above the outer wall of the main body. A deodorizer consisting of a fibrous filter member with a titanium oxide catalyst adhered to its surface and ultraviolet irradiation means, while a fibrous filter is interposed in the downstream duct. Processing device. According to the sixth invention, the required length can be ensured without unnecessarily protruding the exhaust duct as the exhaust means from the outer wall of the device, so that the deodorizing device can have a sufficient length and the deodorizing effect can be enhanced. Furthermore, since a fibrous filter is interposed in the downstream duct, in the process of discharging steam in the processing chamber, it condenses on the surface of the filter to form water droplets, which take in odor components in the exhaust gas and lower the water droplets. And collected in the processing chamber, so that the deodorizing effect as a whole can be further enhanced.
Furthermore, a seventh invention is a garbage disposal apparatus characterized in that a mixture of wood chips and an inorganic material having a set particle size or more is used as a fungus bed material. According to the present invention, even when the woody floor material becomes fibrous due to microorganisms due to long-term use, the fibers are prevented from being entangled with each other by the inorganic material having a certain particle size or more to form a so-called dango-like shape. The microorganisms on the surface can be reliably placed in an aerobic environment, and the decomposition performance can be maintained to the end. According to an eighth aspect of the present invention, there is provided a crushing means for crushing garbage in advance, the crushing means being provided with a plurality of sawtooth-shaped cutting wheels stacked on a pair of rotating shafts, respectively, so as to mesh with each other. A garbage disposal apparatus characterized in that at least one of them has a large diameter. According to the eighth aspect, in addition to the decomposition by the thermophilic microorganisms, the garbage is physically finely divided in advance, so that the adhesion surface area of the microorganisms is increased,
The decomposition potential of the thermophilic microorganisms can be further elicited, and the time for decomposing garbage can be further reduced.
Also, since at least one of the cutting wheels that are superposed in a large number in the axial direction has a large diameter,
The garbage to be thrown in can be reliably taken into the meshing portion of the cutting wheel from the slot. In other words, since the input part is structurally a funnel at the tip, the continuous input from the top causes the garbage compressed by the side walls to become bridge-like, preventing natural falling in the direction of the crushing part. No, the cutting wheel will run idle, but by partially providing a large diameter cutting wheel, it will destroy bridge-like garbage,
It has an excellent effect that garbage can be crushed reliably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the garbage disposal apparatus of the present invention will be described below with reference to the drawings. The garbage disposal apparatus according to the present invention includes a crushing unit 2 for finely crushing garbage input from a garbage input unit 1, and a screw screw type conveying unit 3 for conveying garbage crushed by the crushing unit 2. A garbage processing chamber 5 having therein a bacterial bed carrying thermophilic microorganisms on its surface, and a stirring means 6 for stirring and mixing the garbage transported by the transport means 3 with the bacterial bed in the processing chamber 5; ,
A preheating means 7 for preheating the temperature of the bacterial bed in the processing chamber 5 at a set value lower than the optimum activation temperature of the thermophilic microorganisms of 60 ° C. to 90 ° C. prior to the treatment of garbage; Discharge means 8 for discharging water and carbon dioxide gas generated by decomposition of garbage, and suction means 9 for introducing outside air so that the bacteria bed environment in the processing chamber 5 becomes an aerobic environment. The horizontal cross section of the garbage input section 1 is gradually narrowed downward from the input port 1a, and is most narrowed immediately above the crushing means 2. This is because the area of the input port 1a is increased in consideration of the input of garbage, and the area immediately above the crushing means 2 is larger than the area of the input port 1a in order to surely guide the garbage to the effective portion of the crushing means 2. Is set small. In addition, an opening / closing lid 1C that is opened and closed at the time of putting garbage is installed at the inlet 1a. The crushing means 2 includes a pair of saw-tooth-shaped cutting wheels 2c and 2d fixed to the shafts 2a and 2b, crushes the garbage thrown into the meshing portion of the cutting wheel by the meshing rotation thereof, and lowers the conveying means 3. Are discharged onto the screw 3a. A large number of the cutting wheels 2c and 2d are stacked on each of the shafts 2a and 2b, and two of the cutting wheels 2e and 2f are formed to have a larger diameter than the others. This crushing means crushes on the same principle as a shredder known as a so-called office equipment, and a detailed description is omitted. The conveying means 3 includes a spiral screw 3a driven by a motor 3b and a cylindrical case 3c surrounding the screw 3a. The upper left end of the case 3c is a receiving section 3d for receiving the crushed garbage by the crushing means. The right end communicates with the processing chamber 5 through a plurality of pores, and the garbage conveyed by the screw 3a is configured to be fragmented through the pores and extruded into the processing chamber 5. I have. The processing chamber 5 is provided adjacent to the loading section 1, the crushing means 2, and the transporting means 3 which are vertically arranged side by side, and has a U-shaped cross section. An appropriate amount of a bacterial bed (not shown) made of a mixture of wood chips and an inorganic material such as pumice (silicate) is charged into the processing chamber 5. 60 ° C.-9
A group of thermophilic microorganisms that are most activated at 0 ° C. (having a large decomposition treatment capacity) is supported. Although the thermophilic microorganisms have a higher decomposition potential at room temperature than the room temperature microorganisms, no significant difference in potential is observed at room temperature. The thermophilic microorganisms have a low decomposition ability when left at room temperature, and have an activity temperature of 6%.
It takes 2 to 3 days to reach 0 ° C. or higher, but if it is preliminarily artificially preheated to 40 ° C. to 50 ° C., the action of microorganisms becomes active, and the heat of decomposition causes the bacterial bed temperature to reach 6 ° C. in about 1 hour.
The temperature reaches 0 ° C. to 70 ° C. and rapidly rises to near 90 ° C. in about 2 hours. In addition, wood chips are generally used as the fungal bed material, and there is basically no problem such as implantation of microorganisms. However, when used for a long time, it has an adverse effect on the decomposition treatment of microorganisms. In other words, since wood chips are organic substances, they are gradually decomposed by microorganisms when used for a long period of time, leaving fiber as a hardly decomposable substance.The fibers are entangled with each other to form a dango-like shape and land on the fiber surface. The environment of the microorganisms used becomes an anaerobic environment, and the decomposition performance deteriorates. Therefore, by mixing an inorganic material such as pumice (silicate) having a particle size of 1 cm to 2 cm as a bacterial bed material as in the present embodiment, it is possible to minimize fiber entanglement, and its durability is extremely high. improves. Although it is possible to use only a silicate such as pumice as a bacterial bed material, abrasion due to mutual contact is quicker and durability is inferior. The preheating device 7 includes a liquid jacket 7a formed outside the processing chamber 5 and a plurality of thermocouples 7 disposed inside the liquid jacket 7a.
The thermocouple 7b is energized by control means (not shown), and the temperature of the bacterial bed in the processing chamber (when garbage is not charged) is set at a temperature higher than the microorganism activation temperature of 60 ° C to 90 ° C. The liquid jacket 7a is configured to be heated to a low temperature of about 40 ° C. to 50 ° C. The stirring means 6
The processing chamber 5 includes a rotating shaft 6a rotatably supported at both ends by partition walls 5a and 5b, and a plurality of paddles 6b fixed on the rotating shaft. The inside of the processing chamber 5 is driven by a motor 6c. , And is configured to agitate the garbage and the bacteria bed supplied from the transport means 3. The exhaust means 8 includes an upstream duct 8 a configured to extend in the same direction as the rotation axis 6 a of the stirring means 6 inside the main body 10 including the processing chamber 5, and a set length projecting from the upper surface of the outer wall 10 a of the main body 10. A downstream duct 8b having an upstream opening to the atmosphere is provided between the upstream duct 8a and the downstream duct 8b. The downstream duct 8b communicates with the upstream duct 8a on the suction side and the downstream duct 8b on the discharge side. 8c that communicates with the control unit and a controller 8d that controls the discharge amount of the blower 8c
And The upstream duct 8a is opened at the upper portion of the processing chamber 5 at the upstream opening 8e, and a fibrous filter member 8f having a titanium oxide catalyst adhered to the surface over substantially the entire area in the longitudinal direction is mounted on the upstream duct 8a. The duct 8a is provided with ultraviolet irradiation means 8g for irradiating ultraviolet light corresponding to the filter member 8f. The filter member 8f and the ultraviolet irradiation means 8g constitute a deodorizing device. Further, the downstream duct 8b is provided with a fibrous filter 8h over almost the entire area in the longitudinal direction, and moisture condenses on the surface of the filter in the process of exhausting,
The moisture absorbs the odor components in the exhaust gas and enhances the deodorizing effect. Further, the bottom of the downstream duct is communicated with the processing chamber 5 through the drain pipe 8i, and the water collected at the bottom can be collected in the processing chamber 5 without flowing out to the outside. The control means 8d includes an inverter and a timer (not shown), and is configured to control the switching of the blower 8c between the increasing mode and the decreasing mode at regular time intervals. In addition, the intake means 9 includes an upstream duct 8a.
One end 9b is open to the atmosphere and is communicated with the processing chamber 5 via a number of ejection nozzles 9a. The suction means 9 is not provided with a special forcing means such as a blower, but is communicated with the exhaust means 8 through the processing chamber 5, so that the processing chamber 5 is operated in accordance with the operation of the blower 8C of the exhaust means 8.
Is controlled. Control means 8d
Is in the increasing mode, the intake air is also in the increasing mode, and in the decreasing mode, the intake mode is similarly reduced. The air supplied into the processing chamber 5 by the suction means is supplied in an amount necessary to maintain the aerobic environment. Also, the intake means 9
Each passage of the exhaust means 8 is set such that the pressure in the processing chamber 5 becomes lower than the atmospheric pressure during the operation of the blower 8c. As a result, the processing chamber 5 is always in a negative pressure state, so that the deodorized steam in the processing chamber does not flow out from the gaps between the respective parts of the main body. In addition, the upper part of the processing chamber 5 is formed with a direct input port 5c for directly inputting garbage as needed.
This opening 5c is provided with an opening / closing lid 5d. In this embodiment, the switching control is automatically performed by the control inverter and the timer of the blower. However, the control may be performed manually using only the inverter, or the exhaust amount may be kept constant over the entire processing period. You may.
Further, the displacement may be changed depending on the nature of the garbage (difficulty of decomposition). Since the garbage processing apparatus according to the present invention is configured as described above, the garbage input from the input section is finely crushed by the crushing means 2 and is transported into the processing chamber 5 by the transporting means. In 5, the mixture is uniformly mixed with the bacterial bed by the stirring means 6. At this time, the bacterial bed in the processing chamber 5 is pre-heated to about 40 ° C.
Since the heat of the thermophilic microorganisms is activated by the degree of preheating, the garbage in the processing chamber 5 is decomposed, and the temperature of the bacterial bed is combined with the heat of decomposition generated by the action of the microorganisms. The temperature rapidly rises to 60 ° C. to 90 ° C., which is the formation temperature, and the decomposition of garbage proceeds further. At this time, the processing chamber 5
In the inside, a large amount of water and carbon dioxide gas will be generated by decomposition, but these water and carbon dioxide gas are reliably deodorized and deodorized by the deodorizing devices of the upstream duct 8a and the downstream duct 8b by the operation of the exhaust means. Disinfected and released into the atmosphere. By the operation of the exhaust means, air is introduced into the processing chamber from the suction means, the aerobic environment in the processing chamber 5 is maintained, the decomposition by the thermophilic microorganisms is carried out steadily, and the input garbage is constant. Is reliably decomposed as the processing time elapses. Hereinafter, an experimental example of the garbage processing apparatus according to the present invention will be described. FIG. 6 shows data obtained by injecting 50 kg of vegetable waste with the apparatus of the present invention and measuring the temperature of the bacterial bed and the weight of garbage every 30 minutes. However, the bacterial bed temperature at the start is 50 ° C, and the operation of the blower is the first 30
It is assumed that the minute is set to the decrease mode and thereafter the switching control is alternately performed between the increase mode and the decrease mode every 30 minutes. First, the temperature of the microbial bed rapidly rises from 50 ° C. to 74 ° C. in the first 30 minutes as the first stage (1st), and reaches the first stage (3st) during the second stage (2st) and the third stage (3st). While showing a gradual increase as compared to 1st), the temperature reached 84 ° C. and reached 5 ° C in the fourth stage (4st).
The temperature drops by about 5 ° C. in the next stage, and then rises and falls repeatedly in the twentieth stage (20 st). On the other hand, the weight gradually decreases with the passage of time from the first step (1st) and becomes almost zero at the 19th step (19st). The weight of the garbage is measured by measuring the entire garbage processing apparatus with a weighing scale, and subtracting the weight of the garbage processing apparatus (the weight of the garbage processing apparatus alone) from the measured weight. The thermophilic microorganisms in the processing chamber are preheated in advance from the change in the temperature of the bacterial bed and the change in the weight of the garbage, and are in an active state. It can be seen that they have a constant and high level of processing ability. The temperature of the microbial bed fluctuates in a jerking manner after the fourth stage. This is due to the control of the blower of the exhaust means. When the blower is in the increasing mode, a large amount of moisture and carbon dioxide gas in the processing chamber is discharged. On the other hand, a large amount of air is introduced from the intake means while being exhausted, so that the introduced air lowers the temperature of the germ bed, and when the blower is in the weight reduction mode, the heat generated by the action of microorganisms increases.
The temperature will rise. In this case, the weight change of the garbage in the processing chamber generally shows a substantially constant downward tendency, but from a microscopic viewpoint, the weight change tends to be larger when the blower is in the increasing mode. The higher the temperature, the higher the decomposition ability of the microorganism. However, no matter how much the decomposition proceeds, no change in weight occurs unless the microorganism is discharged to the outside. Therefore, it can be said that the change in weight between the increase mode and the decrease mode of the blower is simply the difference in the amount of discharged moisture generated by decomposition. The second stage (2
In st), the fact that the temperature rises despite the fact that the blower is in the increasing mode is considered to be due to the fact that the microorganisms are more active and generate more heat of decomposition than the cooling effect of the introduced air. Can be

According to the garbage disposal apparatus of the present invention, the decomposition of garbage can be performed in a very short time by optimizing the activity environment in combination with the ability of thermophilic microorganisms.
