DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposal apparatus for decomposing organic waste such as industrial dust, manure, and industrial waste discharged from a food processing plant by bacteria to eliminate the waste. Related to the device.

[0002]

2. Description of the Related Art The amount of organic waste generated daily is enormous. The amount of general waste generated by Japanese people per day is about 1 kg, and the annual amount generated is 50 million tons. The amount of dust generated in each household is about 7 per day.
It is said to be 00g. In a 100,000 household town, 70
Tons of raw dust are generated. In addition, enormous amounts of organic waste are generated in food processing factories, and the amount of manure that cannot be dumped at sea is considerable. Organic waste is incinerated and disposed of. Organic waste has an extremely high moisture content and requires a large amount of thermal energy for incineration. This is because a large amount of energy is required to evaporate water. Therefore, it is a fact that enormous costs are spent for processing organic waste. A method of decomposing raw dust into gases such as carbon dioxide, moisture, and ammonia by the action of bacteria instead of incineration does not have this adverse effect, and can minimize the energy consumed for disposal.

[0003] A treatment method for eliminating organic wastes by using bacteria can be installed in factories where organic wastes are generated, or in waste treatment plants in municipalities, and further downsized to be installed in each household. If there is a device for treating and eliminating organic waste with bacteria at the place of generation, there is no need to transport the organic waste to a treatment plant. Therefore, it is possible to realize an extremely efficient and low-cost ideal disposal that does not require disposal of a large amount of residues such as ash. This saves enormous costs for disposing of organic waste,
Moreover, there is an extremely excellent feature that can be sanitized.

[0004] An extinguishing type device for eliminating organic waste in this way has already been developed. In a conventional extinguishing type treatment apparatus, a microorganism carrier obtained by pulverizing wood such as cedar into rice grains is put in a casing that can be closed, and bacteria are inhabited there. The organic waste is placed in a casing in which bacteria are inhabited, and air is continuously supplied while stirring intermittently. Bacteria decompose organic waste into gases such as water vapor, carbon dioxide gas, ammonia, and methane gas, and disappear. Organic waste is decomposed into gas and is almost gone after treatment. The weight after the treatment becomes incomparably lower than the weight before the treatment. For this reason, organic waste can be introduced every day and efficiently decomposed and eliminated. Since the organic waste disappears, the daily supply of organic waste does not increase the total amount of microbial carriers.

[0005] It is important for a disposal device that decomposes and eliminates organic waste by the action of bacteria to make the environment in which bacteria live in comfortable conditions. Furthermore, it is necessary to uniformly and efficiently eliminate the supplied organic waste,
It is also important that all bacteria living on the microbial carrier work actively.

[0006] To achieve this, the present inventor:
We have developed a waste disposal device as shown in the vertical vertical sectional view of FIG. 1 and the vertical horizontal sectional view of FIG. The apparatus shown in these figures includes a casing 1 for supplying a microorganism carrier and organic waste, a stirring blade 2 for stirring the microorganism carrier and organic waste contained in the casing 1, and a reduction motor for rotating the stirring blade 2. 4 and
A pressurized tank 5 for supplying pressurized air into the casing 1,
A heater 6 for heating air supplied to the pressurized tank 5
A temperature control circuit 7 for detecting the temperature of the air supplied to the casing 1 and controlling the heater 6; and a pressurized air source 8 for supplying air to the pressurized tank 5.

[0007] The casing 1 has a horizontally elongated shape with its lower half along a cylinder, and a supply port 1A for supplying organic waste is opened in the upper part. Supply port 1A
Is closed by a lid 9 that can be opened and closed. Inside the casing 1, a rotating stirring blade 2 is horizontally disposed. The stirring blades 2 have a spiral shape with a pitch opposite to each other so that they can rotate and move the microorganism carrier and the organic waste to the left and right to stir. Further, the stirring blade 2 is rotated close to the bottom surface of the casing 1 to stir the microorganism carrier and the organic waste supplied into the casing 1 as a whole.

[0008]

The disposal apparatus shown in FIGS. 1 and 2 can almost completely decompose supplied organic waste in tens of hours. However, it is difficult to uniformly stir the microorganism carrier and the organic waste in the casing with the stirring blade in the ideal state in the disposal apparatus having this structure. In particular, it is difficult to reduce the load on the motor that rotates the stirrer, reduce damage to the microorganism carrier, and stir the whole uniformly.
This is because the microorganism carrier and the organic waste are simultaneously moved left and right by the spiral stirring blade and stirred. The microorganism carriers that are forcibly transferred and stirred in the horizontal direction rub against each other and have a shorter usable life. In particular, as a microbial carrier, a porous material having fine voids is used in order to inhabit bacteria, and thus it is difficult to obtain sufficient strength. Porous microbial carriers include those obtained by bonding inorganic materials to porous material, wood chips and wood chips cut from wood so that voids are formed as much as possible, chemical fibers and natural wood fibers molded into a predetermined shape, Those obtained by foaming plastic are used alone or in combination of two or more. These microbial carriers have reduced strength as compared to non-porous granules. Furthermore, the higher the porosity of the microbial carrier, the greater the number of voids in which bacteria can inhabit. Therefore, those having excellent physical properties as a microbial carrier have reduced strength.

[0009] Microbial carriers, which are difficult to obtain sufficient strength, fall off the surface and become smaller after being used for a certain period of time, which lowers the habitat of bacteria. When the microbial carrier is worn down from the surface and becomes small, the space where the bacteria live is reduced, and the performance as the microbial carrier is reduced. For this reason, it is necessary to replace the microbial carrier that has become worn and small with a new one. The longer the usable life of the microorganism carrier, the lower the running cost and the more convenient it can be used. In particular, a device that decomposes and eliminates organic waste by the action of bacteria is an important feature that minimizes the total amount of waste. If it is necessary, the greatest features will not be used effectively. For this reason, it is extremely important for a device of this type that the period during which the microorganism carrier can be used, in other words, the life of the microorganism carrier can be extended. In addition, it is extremely important that a microbial carrier having many fine voids and having insufficient strength can be used effectively for a long time.

The present invention has been developed with the object of realizing this fact. An important object of the present invention is to ideally combine a microorganism carrier with an organic waste so that an unreasonable force does not act on the microorganism carrier. It is an object of the present invention to provide a disposal device that decomposes and dissolves organic waste that can be uniformly stirred in a stable state with bacteria. Another important object of the present invention is to provide a disposal apparatus which can reduce an entire installation area and efficiently dispose of a large amount of organic waste by decomposing and removing organic waste by bacteria. .

[0011]

According to the present invention, there is provided a disposal apparatus for decomposing and removing organic waste with bacteria, comprising: a casing 1 for accommodating a microbial carrier for inoculating bacteria; and a microbial carrier supplied to the casing 1. The apparatus includes a stirrer 10 for stirring organic waste and an air supply device 11 for supplying air to a mixture of the microorganism carrier and the organic waste to supply oxygen to bacteria living in the microorganism carrier. This waste device is stirred by the stirrer 10 while supplying air with the air supply device 11, and decomposes and eliminates organic waste by bacteria living on the microorganism carrier.

Further, in the disposal apparatus of the present invention, the casing 1 is of a vertical type, and a stirrer 10 is provided in the casing 1 which extends vertically and transports the microorganism carrier and the organic waste in the ascending direction. Has been established. The stirrer 10 includes a screw shaft 3 to which the screw fins 19 are fixed, and a vertical cylinder 20 disposed on the outer periphery of the screw shaft 3. Screw shaft 3 that rotates inside vertical cylinder 20
Raises the microorganism carrier and the organic waste along the vertical cylinder 20. The microorganism carrier and the organic waste raised in the vertical cylinder 20 are discharged from the upper end of the vertical cylinder 20 and descend in the casing 1.

The microorganism carrier and the organic waste stirred in this state are stirred in the casing 1 so as to convect. Then, the inside of the vertical cylinder 20 is raised, and the vertical cylinder 2
Stir in a state of falling outside of 0. The microorganism carrier and the organic waste in the vertical cylinder 20 are raised by the screw shaft 3. The screw shaft 3 raises the microorganism carrier and the organic waste by a screw screw fin 19 in a spiral manner. The microbial carrier raised in this state is not pressed, but is dispersely dispersed, and is lifted by the screw fins 19 to be raised without difficulty. For this reason, the vertical cylinder 2
The microbial carrier that rises inside 0 is raised without being damaged and dispersing the microbial carrier into pieces so that voids are formed therebetween. Further, the microorganism carrier discharged into the casing 1 from the upper end of the vertical cylinder 20 falls naturally and is sucked from the lower end of the vertical cylinder 20.
The microorganism carrier that naturally falls in the casing 1 falls smoothly and without difficulty by its own weight, instead of being forcedly fed by the stirring blade 23. Therefore, both the microorganism carrier falling in the casing 1 and the microorganism carrier rising in the vertical cylinder 20 can be smoothly and smoothly transferred with very little damage. Furthermore, in the casing 1, the microorganism carrier and the organic waste that are stirred in a convection state of rising and lowering are

[0016]

Embodiments of the present invention will be described below with reference to the drawings. However, the following examples illustrate a disposal device that decomposes and eliminates organic waste with bacteria to embody the technical idea of the present invention,
The present invention does not specify the following disposal devices for decomposing organic waste by bacteria and eliminating the same.

The disposal apparatus shown in FIG. 3 for decomposing and removing organic waste by bacteria is composed of a casing 1 for supplying a microorganism carrier and organic waste, a microorganism carrier and organic waste supplied to the casing 1. A stirrer 10 for stirring
Supplying air to the mixture of microbial carrier and organic waste,
An air supply device (11) for supplying oxygen to bacteria living in the microorganism carrier.

The casing 1 has an overall shape in which a cylinder is vertically set and a lower portion thereof is tapered.
An organic waste supply port 1A is opened at the upper end of the casing 1, and a discharge port 1B is opened at the lower part. Supply port 1
A and the outlet 1B are blocked in the step of eliminating organic waste with bacteria.

The disposal apparatus of the present invention is used for disposing both solid waste such as fresh dust and liquid waste such as manure. When solid waste is eliminated by the action of bacteria, it hardly remains. For this reason, the apparatus for treating solid waste can be thrown in one after another from the supply port 1A and discarded. Therefore, the outlet 1B is opened when exchanging the microbial carrier and used to discharge the microbial carrier.

However, liquid waste such as manure is
When the organic matter contained in the liquid is eliminated by the action of bacteria, water remains. Therefore, it is necessary to discharge the treated water from the outlet 1B after treating the organic waste. When draining the treated water, it is necessary to provide a porous material such as a wire mesh at the outlet 1B so that the microorganism carrier is not discharged together.

FIGS. 4 and 5 are a front view and a horizontal sectional view of the discharge port 1B. In the structure of the outlet 1B shown in these figures, a window is opened in the casing 1, a frame 12 is fixed to the periphery of the window, and a door 14 is connected to the frame 12 via a hinge 13. Inside the door 14, a perforated plate 15, which is a metal net, is provided. Further, a drain pipe 16 for draining treated water with the door 14 closed is fixed to the door 14. The door 14 is tightly attached to the frame 12 via a packing so that water does not leak from between the door 14 and the frame 12 in a closed state. The door 14 is screwed to the frame 12 on the side opposite to the hinge 13 to close the window in a watertight manner.

The frame 12 has sliding grooves 17 in the vertical frames on both sides so that the perforated plate 15 can be pulled out upward. In the sliding groove 17, a perforated plate 15 for fixing a wire mesh to a rectangular frame is inserted so as to be able to be taken in and out. The perforated plate 15 has a structure in which a punching plate and a wire mesh are laminated. The punching plate is disposed inside the casing 1, and a wire mesh is disposed outside the punching plate. Perforated plate 1 with a punching plate inside
No. 5 has such a feature that the microorganism carrier can move smoothly on the inside as a sufficient strength.

The door 14 having the drain pipe 16 can drain treated water in a closed state. The drain pipe 16 is connected to a drain pipe 18 via a drain valve.

The stirrer 10 includes a screw shaft 3 to which the screw fin 19 is fixed, and a vertical cylinder 20 disposed on the outer periphery of the screw shaft 3. The screw shaft 3 is decelerated outside the casing 1. It is connected to the motor 4. The stirrer 10 raises the microorganism carrier and the organic waste along the vertical cylinder 20 with the screw shaft 3 rotating inside the vertical cylinder 20. The vertical cylinder 20 is vertically fixed to the center of the cylindrical casing 1 via an arm, and has upper and lower ends opened in the casing 1. The upper end of the vertical cylinder 20 is opened at the top of the casing 1, and the lower end is opened at the bottom of the casing 1.

The vertical cylinder 20 has a tapered plate 21 fixed to the periphery of the upper end. The tapered plate 21 causes the microorganism carrier and the organic waste discharged from the vertical cylinder 20 to drop on the outer periphery of the casing 1. The taper plate 21 is an umbrella-shaped metal plate, and the microorganism carrier and the organic waste supplied thereon are naturally dropped and uniformly dispersed in the casing 1. Organic waste such as manure supplied from the supply port 1A is also supplied onto the tapered plate 21 to be dispersed and supplied into the casing 1. Therefore, FIG.
Is a supply pipe 22 connected to the supply port 1A.
Are opened above the tapered plate 21.

The screw shaft 3 is disposed vertically at the center of the vertical cylinder 20. The screw shaft 3 has a rotatable watertight structure and penetrates the bottom of the casing 1. The screw shaft 3 is vertically connected to the casing 1 via bearings via bearings. The bearing that connects the lower portion of the screw shaft 3 to the casing 1 has a watertight structure.

The screw shaft 3 rotates, and a screw fin 19 that can move the microorganism carrier and the organic waste up along the vertical cylinder 20 is fixed to the outer periphery. Further, a scraping blade 23 rotating along the bottom of the casing 1 is fixed to a lower end of the screw shaft 3. The scraping blades 23
The microorganism carrier and the organic waste are prevented from adhering to the tapered portion on the bottom surface of the casing 1.

The lower end of the screw shaft 3 is connected to a reduction motor 4 via a sprocket 24 and a chain 25 outside the casing 1 and is rotated by the reduction motor 4.
After operating the deceleration motor 4 for a certain period of time, the deceleration motor 4 performs an intermittent operation of stopping for a certain period of time to rotate the screw shaft 3.

The air supply device 11 is provided with two air injection tubes 26 extending vertically in the outer periphery of the vertical cylinder 20 and arranged vertically. The air injection pipe 26 is provided with an injection port 26A for injecting air at regular intervals, as shown in FIG.
It is open apart . The injection port 26A is provided in the casing 1
Inject air toward outside. The injection port 26A of the air injection pipe 26 may be clogged. Clogged injection port 26A
In order to easily clean the air tube, the air injection tube 26 is connected to the vertical tube 20 so that it can be pulled out. The vertical cylinder 20
A ring 27 into which the air injection pipe 26 is inserted is fixed to the outer periphery. The ring 27 is fixed to the vertical cylinder 20 in two vertical rows,
The air injection pipe 26 is inserted into each ring 27 from the top to the bottom. Further, the air injection tube 26 has a tapered lower end so as to be easily inserted into the ring 27. The air injection pipe 26 of this structure is a vertical cylinder 2
It has the feature that it can be easily inserted into and removed from the 0 ring 27.

The air injected into the casing 1 from the air injection pipe 26 supplies oxygen to bacteria living on the microorganism carrier. Further, the temperature of the air injected from the air injection pipe 26 can be controlled to adjust the temperature of the microorganism carrier to a temperature at which the bacteria actively work. The optimal temperature at which bacteria can comfortably grow and actively decompose organic waste is 38-50 ° C. As the temperature drops below 38 ° C., the bacteria become inactive. When the temperature rises to 50 ° C. or higher, aerobic bacteria stop working actively and anaerobic bacteria propagate. When anaerobic bacteria grow, the odor of the exhaust gas becomes worse. When the temperature of the microorganism carrier is higher than 50 ° C., a large amount of outside air is injected into the casing 1 to achieve a comfortable temperature.

However, in winter, the temperature of the outside air is too low, so that when the outside air is injected into the casing, the temperature of the microorganism carrier may be too low and the organic waste may not be decomposed efficiently in a short time. This problem is caused by incorporating a heater in the casing or heating the vertical cylinder with a heater,
The microbial carrier can be warmed.

Furthermore, the temperature of the microorganism carrier can be controlled by heating the air injected from the air injection pipe 26. The air injection tube 26 that injects the temperature-controlled air is:
It is connected to a pressurized tank 5 that stores temperature-controlled air. The pressurized tank 5 is connected to a pressurized air source 8 such as a blower or a compressor, and stores pressurized air heated to a set temperature. The pressurized tank 5 has, for example, 0.1 to 1
Store air pressurized to 0 kg / cm ² . A flow control valve 28 is connected between the pressurized tank 5 and the air injection pipe. The flow control valve 28 adjusts the opening degree, and the air injection pipe 26
Adjust the amount of air injected from and the injection pressure. Flow control valve 2
When the number 8 is reduced, the amount of air to be injected is reduced, and the injection pressure is reduced. The air injection amount is adjusted to an optimum value in consideration of the capacity of the casing 1. The casing 1 having a daily processing amount of 300 kg has an air injection amount of, for example, 0.1 kg.
1 to 2.5 m ³ / min, preferably 0.2 to 1.5 m
³ / min, more preferably 0.3 to 1 m ³ / min
Set to. The air pressure injected from the air injection pipe 26 to the casing 1 is, for example, 0.1 to 0.1 so that the injected air can pass through the gap between the microorganism carrier and the organic waste.
5 kg / cm ² , more preferably about 0.2 kg / cm
Set to ² .

The pressurized tank 5 has a heater 6 fixed outside for heating the air stored therein to a set temperature.
The outside of the heater 6 is insulated to prevent heat radiation. The heater 6 for heating the pressurized tank 5 is bonded to the switch 29 and the power supply 30 in series. When the switch 29 is on, the heater 6 is energized to heat the pressurized tank 5. The switch 29 that controls the energization of the heater 6 detects the temperature of the microorganism carrier or is controlled by a temperature sensor 31 that detects the temperature of the discharge side of the flow control valve 28, and controls the air in the pressurized tank 5 of the heater 6. Adjust the temperature. The set temperature of the air stored in the pressurized tank 5 is set to a temperature at which the temperature of the microorganism carrier is, for example, 38 to 50 ° C, preferably 38 to 45 ° C.

When the temperature of the outside air surrounding the casing 1 is set to 15 ° C. or higher, the temperature of the microorganism carrier becomes slightly higher than the temperature of the air injected from the air injection pipe 26. In particular, when the microbial carrier actively decomposes organic waste, in other words, when the organic waste is supplied for two to three hours, the temperature of the microbial carrier becomes considerably higher than the ambient temperature. This is because microorganisms actively decompose organic waste. The day after the organic waste was introduced, that is, after about 24 hours, the organic waste was almost completely decomposed,
It disappears and the temperature of the microbial carrier drops. The method of detecting the temperature of the microbial carrier and controlling the air temperature of the pressurized tank 5 is as follows. When the microbial carrier actively decomposes organic waste, the air temperature of the pressurized tank 5 is set low, After completely decomposing the organic waste, the air temperature of the pressurized tank 5 is set high. This method has a feature that the temperature of the microorganism carrier can always be controlled to an ideal temperature.

The disposal apparatus shown in FIG. 3 decomposes and eliminates solid or liquid organic waste in the following manner. The casing 1 is filled with a bacterial microbial carrier. As the microbial carrier, a porous material obtained by pulverizing wood such as cedar into rice grains is preferably used. Bacteria inhabit a myriad of fine voids in a porous microbial carrier. Bacteria inhabiting the microorganism carrier are aerobic bacteria, anaerobic bacteria, facultative anaerobic bacteria and the like. In addition, microbial carriers include:
In addition to the bacteria, preferably an enzyme is added. As shown in FIG. 3, the amount of the microorganism carrier to be filled in the casing 1 is such that the upper surface level of the microorganism carrier is located below the upper end of the vertical cylinder 20.

With the microorganism carrier in the casing 1, air is injected from the air injection pipe 26. The air injected from the air injection pipe 26 passes through the gap between the microorganism carriers and heats the microorganism carriers to a set temperature. Air injection pipe 2
The temperature of the air injected from 6 is about 38-5
The temperature is set at 0 ° C., preferably about 38 to 45 ° C. The flow rate and the injection pressure of the air injected into the casing 1 are adjusted by a flow adjustment valve 28. 5 m ^{3 for} casing 1
The apparatus for storing microbial carriers of the present invention has an air pressure supplied to the air injection pipe 26 of 0.15 kg / cm ² and an air flow rate of 0.4 m.
³ / min. The air injection tube 26 continuously injects air.

The organic waste is supplied while rotating the screw shaft 3. Liquid organic waste is supplied to supply pipe 2
2 is supplied onto the tapered plate 21. When supplying the organic waste, the screw shaft 3 is rotated to sufficiently mix the organic waste with the microorganism carrier. The screw shaft 3 raises the microorganism carrier and the organic waste in the vertical cylinder 20 and convects the microorganism carrier and the organic waste to fall between the vertical cylinder 20 and the casing 1 to stir the microorganism carrier and the organic waste.

After sufficiently mixing the organic waste and the microorganism carrier, the screw shaft 3 rotates intermittently to stir the organic waste and the microorganism carrier. Screw shaft 3
For example, the rotation is performed for 5 minutes, and the rotation is stopped for the next hour. The stirring time can be 2 to 20 minutes.
The rest time of the screw shaft 3 can be set to 20 minutes to 2 hours. If you increase the pause time relative to the rotation time,
Electricity consumption for rotating the screw shaft 3 can be reduced. However, if the pause time is too long, the microorganism carrier and the organic waste cannot be sufficiently stirred, and cannot be efficiently decomposed and eliminated.

Stirred intermittently with the screw shaft 3,
When the air is continuously supplied to the air injection pipe 26, bacteria living in the microbial carrier convert organic waste into carbon dioxide,
Decomposes into gas such as moisture and ammonia and disappears. Bacteria inhabiting the microbial carrier, after supplying organic waste for several hours, rapidly grow and actively decompose the organic waste. Twenty-four hours after the input of the organic waste, that is, the next day, the organic waste is almost completely decomposed and disappears.

[0040]

Industrial Applicability The disposal apparatus of the present invention for decomposing and removing organic waste by bacteria has a feature that the microorganism carrier can be uniformly stirred without exerting an excessive force. This is because the apparatus of the present invention provides a vertical cylinder extending vertically in the casing, and rotates the screw shaft inside the vertical cylinder to raise the microorganism carrier and the organic waste. The microorganism carrier rising inside the vertical cylinder is moved while being lifted upward by the fins of the screw shaft. Since the microbial carrier that is about to fall by its own weight is lifted and moved in the opposite direction to the falling direction, the microbial carrier is transferred in a state of being pulled apart vertically, contrary to being pressure-fed, and it is extremely easy It is raised smoothly. The microorganism carrier that has moved up the vertical tube is transferred into the casing from the upper end of the vertical tube, but does not fall down by its own weight in the casing and is forcibly transferred. In particular, since the microorganism carrier falling in the casing is lifted from the lower end and falls under its own weight, it falls very smoothly and without difficulty. For this reason, when the microorganism carrier is lifted up the vertical cylinder and further falls in the casing, no excessive pressure is applied, the damage is significantly reduced, and the microorganism carrier can be used for a long time.

[0041] Therefore, the microbial carrier has features that it can be used for an extremely long time, since the space for inoculating bacteria is not crushed, and the whole is small and wear is reduced. Therefore, the device of the present invention has features that the time for replacing the microorganism carrier with a new one can be lengthened, the maintenance can be simplified, and the running cost can be reduced.

Further, the bacteria of the present invention can be stirred in a state where the microorganism carrier and the organic waste are lifted up in a vertical cylinder, supplied into the casing from the upper end and dropped, so that the whole is convected. The feature of uniformly stirring the carrier and the organic waste without stagnation can be realized.

Further, since the disposal apparatus of the present invention can vertically stir the casing and stir the microorganism carrier and the organic waste in an ideal state, the entire installation area can be reduced and a large amount of the organic waste can be reduced. It also realizes the feature that it can be disposed of efficiently.
