DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for decomposing organic raw material dust with bacteria for disposal.

[0002]

2. Description of the Related Art An enormous amount of dust is generated in households nationwide. 100,000 households generate about 70 tons of raw dust per day. Raw dust is incinerated and discarded. Since raw dust has a very high moisture content, it requires a large amount of heat 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 used for processing the dust. Instead of incineration,
The method of decomposing raw dust with bacteria does not have this adverse effect and can limit the energy consumed for disposal.

[0003] When an apparatus for treating garbage using bacteria is installed in each household, garbage can be decomposed and disposed of at home. Therefore, there is no need to collect fresh dust. Also, there is no need to incinerate the dust. In addition, each household does not need to bring the dust to a specific set point on the day of collection. The apparatus for treating garbage caused by bacteria can save enormous costs for discarding garbage, and can immediately treat garbage generated at home.

[0004] Devices for treating raw dust in this way have already been developed. In a conventional apparatus, a hygroscopic member such as cedar sawdust is placed in a garbage decomposition chamber of a case, and bacteria and garbage are placed therein and agitated.
The device of this structure allows bacteria to propagate in sawdust,
It decomposes organic dust into gas and water. Therefore, fresh dust is reduced after the treatment so as to be incomparable with that before the treatment. Aerobic bacteria are used as bacteria. Facultative anaerobic bacteria may be added in addition to aerobic bacteria. Aerobic bacteria decompose raw dust efficiently in a short time. In order for aerobic bacteria to work actively, it is necessary to supply sufficient oxygen to the aerobic bacteria.

[0005]

The conventional apparatus operates a ventilation fan 4B of a ventilation means 4 as shown in FIG.
Oxygen is supplied to the aerobic bacteria of the moisture absorbing member 1 which is stirred in the fresh dust decomposition chamber 2. The moisture absorbing member 1 is not continuously stirred. This is to reduce the power consumption of the deceleration motor 3B for driving the stirring member 3 as much as possible. Stirring member 3
It is preferable to increase the operation time of
The power consumption increases in proportion to the operation time, and the electricity bill increases. The garbage processing device continuously decomposes the garbage by bacteria of the moisture absorbing member at 24 hours. That is, it is necessary to keep the operating state all day. If you stop driving for a long time,
This is because bacteria that inhabit the moisture absorbing member are killed.
Therefore, this type of device is not an electric appliance used only when used, such as a television or a washing machine.
This is an electrical product that requires an extremely long operation time. For this reason,
Reducing power consumption is extremely important.
In order to reduce power consumption, conventional devices operate the stirrer intermittently. The stirring member is operated for several minutes, for example, once every 30 minutes to one hour. Reducing the operation time makes it difficult to sufficiently stir the moisture absorbing member. In other words, it is difficult to supply sufficient oxygen to the aerobic bacteria that inhabit the moisture absorbing member. For this reason, the activity of aerobic bacteria is reduced, and the ability to decompose raw dust is reduced. In order to activate the aerobic bacteria, it is necessary to extend the operation time of the stirring member. Therefore, the power consumption and the resolution rate of the aerobic bacteria are mutually contradictory characteristics, and it is extremely difficult to satisfy both. difficult.

When the stirring member 3 is operated, the moisture absorbing member 1 is stirred, and oxygen is supplied to aerobic bacteria living inside the moisture absorbing member 1. Aerobic bacteria decompose raw dust into gas and moisture, but the decomposed gas contains malodorous components. This is because bacteria decompose raw dust and decompose it into gas. If exhaust gas of raw dust is exhausted directly, a bad smell will drift in the kitchen.
In order to prevent this adverse effect, the air to be exhausted is deodorized by deodorizing means and exhausted outside the machine. Unfortunately, even if the concentration of the malodorous gas is very low, the malodorous gas is continuously exhausted for 24 hours, so that it fills the kitchen and the like, causing a malodor.

In order to prevent this adverse effect, deodorizing means 5 for supplying ozone and deodorizing is used. Further, a means for deodorizing malodor by a catalyst or a means for adsorbing malodor and deodorizing it is used. These deodorizing means 5
When the amount of supplied air increases, it becomes difficult to reliably deodorize. The deodorizing means 5 for supplying ozone needs to supply a large amount of ozone and thoroughly mix it with the air of the malodorous gas in order to completely deodorize the malodor. The increased supply of ozone makes the ozone generator expensive. Further, when a large amount of ozone is supplied, there is a problem that ozone that is not consumed for decomposing the bad smell is exhausted outside the apparatus. For this reason, it is necessary to use a catalyst that decomposes ozone into oxygen, and it is necessary to convert ozone into oxygen using a large amount of catalyst, which increases the cost of the deodorizing means. The cost of deodorizing means for deodorizing by decomposing or adsorbing odors with a catalyst also increases as the amount of air to be treated increases. In order to design the deodorizing means 5 at a low cost, it is necessary to reduce the amount of air ventilated to the fresh dust decomposition chamber. Unfortunately, this also reduces the supply of oxygen to the aerobic bacteria that inhabit the hygroscopic member. This is because the ventilation volume of the fresh dust decomposition chamber is reduced. Therefore, deodorizing exhaust air and activating aerobic bacteria are mutually exclusive characteristics, and it is extremely difficult to satisfy both at the same time.

The present invention has been developed for the purpose of solving an extremely difficult problem, which is an extremely important characteristic for fresh dust processing equipment, and is advantageous in reducing power consumption and ventilation air volume. It is an object of the present invention to provide a processing device for garbage that actively decomposes garbage by decomposing garbage efficiently in a short time.

[0013]

The garbage processing apparatus of the present invention decomposes garbage by performing the following operations. Bacteria including aerobic bacteria inhabit the moisture absorbing member 1 such as sawdust filled in the biodegradation chamber 2. Bacteria break down the supplied dust into gas and water. Moisture and gas decomposed from raw dust
The air is discharged from the biodegradation chamber 2 to the outside by the ventilation means 4.

The fresh dust decomposition chamber 2 is separated into a suction side 11 and an exhaust side 12 by a separation partition 4A. The separation partition 4A that separates the fresh dust decomposition chamber 2 has its lower end extended to the inside of the moisture absorbing member 1 or to the vicinity of the upper surface level of the moisture absorbing member 1. In the device in which the lower end of the separation partition 4A is extended to the inside of the moisture absorbing member 1, as shown in FIG. 2, outside air flowing into the suction side 11 passes through the inside of the moisture absorbing member 1 and is sent to the exhaust side 12. That is, the air to be ventilated passes through the interior of the moisture absorbing member 1 and is exhausted. Therefore, the air to be ventilated is efficiently supplied to the aerobic bacteria that inhabit the moisture absorbing member 1.

As shown in FIG. 3, the lower end of the separation wall 4A is not extended to the inside of the moisture absorbing member 1, but is extended to the vicinity of the upper surface level of the moisture absorbing member 1. At 4A, the direction is changed downward and sprayed on the moisture absorbing member 1. Therefore, as shown by the chain line arrow in FIG. 3, the outside air to be sucked is efficiently supplied to the aerobic bacteria of the moisture absorbing member 1 and exhausted without passing through the exhaust port 7 from the suction port 10.

Further, as shown in FIG. 4, a device in which a gas-permeable filter 14 that allows air to pass through but does not pass through the moisture-absorbing member 1 is installed in the suction port 10 opened on the bottom surface is made to pass through the gas-permeable filter 14. Inhale outside air. Since the air permeable filter 14 is stretched on the surface that comes into contact with the moisture absorbing member 1, the air that has passed through the air permeable filter 14 directly contacts the moisture absorbing member 1, and the air that is further inhaled is the air absorbing member 1.
Is ventilated by passing through the inside, so that oxygen is efficiently supplied to the aerobic bacteria living in the moisture absorbing member 1.

As described above, the fresh dust treatment apparatus of the present invention efficiently contacts the outside air sucked into the fresh dust decomposition chamber 2 with the aerobic bacteria in the moisture absorbing member 1, thereby increasing the amount of air to be sucked. Without supplying oxygen to aerobic bacteria efficiently. This makes it possible to supply a large amount of oxygen to the aerobic bacteria without extending the operation time of the stirring member 3. Therefore, a large amount of oxygen is supplied to the aerobic bacteria that inhabit the moisture absorbing member 1 without increasing the ventilation volume of the air, and the aerobic bacteria actively work to decompose the raw dust efficiently in a short time.

The opening / closing lid 9 is connected via a hinge so that it can be opened and closed. When the open / close lid 9 is opened and fresh dust is supplied, and the open / close lid 9 is closed, the odor in the fresh dust decomposition chamber 2 does not leak.

The fresh dust decomposition chamber 2 is filled with sawdust as the moisture absorbing member 1. Sawdust has preferable physical properties as the moisture absorbing member 1. This is because it has a large amount as waste, is inexpensive, and has appropriate hygroscopicity. Cedar sawdust is most suitable for sawdust. However, instead of sawdust, any hygroscopic powdery material capable of inoculating bacteria can be used for the moisture absorbing member 1.

As the bacteria added to the moisture absorbing member 1, only aerobic bacteria can be used. However, facultative anaerobic bacteria can also be added in addition to aerobic bacteria. More preferably, an enzyme is added in addition to the bacteria. Aerobic bacteria, facultative anaerobic bacteria and enzymes added to the moisture absorbing member 1 include, for example, ABC Japan Co., Ltd. (3 Kuramae, Taito-ku, Tokyo)

The air is forcibly exhausted. The ventilation means 4 includes a separation partition 4A and a ventilation fan 4B. The separation partition wall 4A connects the fresh dust decomposition chamber 2 to a suction side 11 connected to a suction port 10 for sucking outside air, and an exhaust side connected to an exhaust path 7 for discharging air in the fresh dust decomposition chamber 2. And 12.

In the apparatus shown in FIG. 2, the lower end of the separation partition 4A extends to the inside of the moisture absorbing member 1. Inhaled air
This is because the gas is exhausted by passing through the moisture absorbing member 1. The separation partition wall 4A shown in this figure has a lower edge extending from the outer periphery of the blade of the stirring member 3 to the center and further to the vicinity of the shaft of the stirring member 3. The partition wall 4A is disposed between the blades so that the partition wall 4A does not collide with the blade of the rotating stirring member 3. Further, although not shown, the separation partition wall 4A can also extend below the shaft.
This separation partition 4A is provided with a hole through which the shaft passes,
Alternatively, a portion through which the shaft passes is cut out. The separation partition wall 4A extended to the lower side can supply the air to be sucked into the interior of the moisture absorbing member 1 and more efficiently supply the air to the aerobic bacteria of the moisture absorbing member 1.

Further, the apparatus shown in FIG.
Are provided with a plurality of through holes 13. The through-hole 13 allows a part of air to pass through from the suction side 11 to the exhaust side 12 to be bypassed. The separation wall 4A having this structure can adjust the size and number of the through holes 13 to adjust the amount of air to be bypassed from the suction side 11 to the exhaust side 12. Through hole 1
The separation partition 4A with 3 allows some air to be bypassed,
The remaining air passes through the inside of the moisture absorbing member 1. With this structure, the amount of air that bypasses the through hole 13 can adjust the amount of air ventilation. The air ventilated to the biodegradation chamber 2 supplies oxygen to the aerobic bacteria inhabiting the moisture absorbing member 1 and exhausts gas and moisture generated by decomposing the biodust outside the machine. I will. The separation partition wall 4A having the through holes 13 adjusts the ventilation amount of the air with the amount of air to be bypassed so as to supply an optimal amount of oxygen to the aerobic bacteria and exhaust the decomposed gas and moisture. Can be designed.

The apparatus for treating fresh dust shown in FIG.
The lower end of A is close to the upper surface level of the moisture absorbing member 1.
In the device having this structure, the air to be ventilated is turned downward by the separation partition wall 4A and is sprayed on the moisture absorbing member 1. The air blown to the moisture absorbing member 1 efficiently supplies oxygen to the aerobic bacteria of the moisture absorbing member 1 in a stirring state. In the apparatus for treating fresh dust having this structure, a part of the air ventilated in the same manner as the through hole 13 in FIG. 2 is bypassed through the gap between the lower end of the separation partition 4A and the moisture absorbing member 1. The amount of air to be bypassed can be adjusted by the gap between the lower end of the separation partition 4A and the moisture absorbing member 1. Reducing this gap reduces the amount of bypassed air, and increasing it increases the amount of bypassed air.

Further, the raw dust processing apparatus shown in FIG.
An intake port 10 for the outside air is opened on the bottom surface of the fresh dust decomposition chamber 2 which is the contact surface of the moisture absorbing member 1. A breathable filter 14 is stretched over the suction port 10. Breathable filter 1
Reference numeral 4 denotes a breathable sheet material that allows air to pass through but does not allow the moisture absorbing member 1 to pass through. The gas permeable filter 14 is smaller than the moisture absorbing member 1, and a plastic microporous membrane having a space through which air can pass can be used. As shown in the figure, the fresh dust treatment apparatus having this structure can adjust the ventilation rate of air by opening an intake section 18 at an upper portion and allowing a small amount of outside air to be sucked from the intake section .

In the apparatus for treating fresh dust shown in FIGS. 2 and 3, ventilation fans 4B are provided at both the inlet 10 and the outlet. The ventilation fan 4B of the suction port 10 sucks in outside air and forcibly supplies it to the biodegradation chamber 2. The ventilation fan 4B of the exhaust path 7 forcibly exhausts the air in the fresh dust decomposition chamber 2. The fresh-dust treatment device provided with the ventilation fan 4B in both the suction port 10 and the exhaust path 7 has a feature that the air can be sufficiently circulated to the inside of the moisture absorbing member 1 using the small ventilation fan 4B. As shown in FIG.
The apparatus provided with one ventilation fan 4B supplies sufficient oxygen to the aerobic bacteria living inside the moisture absorbing member 1 by using the ventilation fan 4B having a large capacity.

The air exhausted from the garbage decomposition chamber 2 is an odorous gas containing water and gas obtained by decomposing garbage. In order to deodorize odorous gas, a deodorizing means 5
Are linked. The deodorizing means 5 includes an ozone supplying means 5A
, A stirring section 5B, and a catalyst 5C. The deodorizing means 5 is provided with a stirring section 5B in the exhaust path 7 in order to deodorize the malodorous gas with ozone and to remove and remove the moisture contained in the air.

The stirring section 5B is extended vertically and
A plurality of baffle plates 6 are provided. The exhaust path shown in the figure
Four rows of stirrers 5B extending vertically are provided, and the stirrers 5B of each row are connected to be adjacent at the upper end and the lower end.

The baffle plate 6 of the stirring section 5B is adhered and fixed to the inner surface of the casing of the stirring section 5B in such a manner as to be inclined downward toward the center of the stirring section 5B. The baffle plate 6 shown in the figure has a rectangular shape, and three sides, both sides and a rear end edge, are fixed to the inner surface of the casing of the stirring section 5B. The baffle 6 shown in FIG.
It is fixed to the casing at an angle of about 45 degrees to the horizontal plane so that the dew water can flow down smoothly. However, the inclination angle of the baffle plate 6 with respect to the horizontal plane may be in the range of 15 to 60 degrees.

The baffle plate 6 shown in the figure is provided with a stirrer 5B so that air is made to flow in a zigzag manner to stir more efficiently.
Of the baffle plate 6 provided on both sides of the stirrer 5
B are arranged so as to protrude further than the center thereof and to be wrapped with each other being displaced vertically. Furthermore, the stirring portions 5B in the second and fourth rows from the left have a feature that the air flows from the bottom to the top, so that the stirring portion 5B is efficiently stirred at the tip of the baffle plate 6. This is because a vortex is likely to be generated on the upper surface of the baffle plate 6 that is leeward at the tip of the baffle plate 6.

Further, as shown in the figure, the stirrer 5B for causing air to flow in a zigzag shape has a substantially longer overall length of the passage, and stirs the air more efficiently to efficiently convert ozone and odorous gas. There is a feature that can be mixed well.

Further, the agitating section 5B shown in the figure has a drain pipe 15 connected to the bottom. The drain pipe 15 is bent in an inverted U-shape in the middle to form a trap so as to discharge water and not air. The trap is blocked by the water that accumulates in it, preventing the air from being discharged. The device that connects the drain pipe 15 to the bottom of the agitating section 5B has the feature that the dew condensation water can flow out of the exhaust path 7, so that the moisture of the air passing therethrough can be efficiently removed.

However, the drain pipe 1 is always provided in the stirring section 5B.
5 need not be connected. Stirrer 5B without drain pipe 15
The dew water adhering to the surface of the baffle plate 6 and flowing down collects at the bottom. The water that accumulates here is vaporized again into the air and discharged when the relative humidity of the air decreases. However, when the relative humidity of the air is high, the amount of water remaining at the bottom evaporating into the air is small, and the water does not immediately evaporate. Therefore, when the relative humidity of the air is high, the water condensed on the baffle plate 6 separates and accumulates at the bottom of the stirring unit 5B, and when the relative humidity of the air decreases, the water collected at the bottom of the stirring unit 5B evaporates again. Discharged with the air. Stirrer 5 when relative humidity of air is low
Even if the water that accumulates at the bottom of B evaporates, the relative humidity under the air is low, so that the humidity does not increase abnormally. For this reason, the air passing through the catalyst 5C does not condense.

The exhaust path 7 connects the ozone supply means 5A to the inflow side of the stirring section 5B. The ozone supply means 5A is
Outside air is sucked from the outside air suction passage, ozone is added to the sucked air, and the ozone is supplied to the inflow side of the stirring section 5B, which is the exhaust passage 7. As the ozone supply means 5A, for example, a means is used in which a high voltage is applied to opposing electrodes, a discharge is caused between the electrodes, air passes therethrough, and a part of oxygen contained in the air is converted into ozone. The ozone supply means 5A shown in the drawing includes a fan 16 for sucking outside air. The fan 16 takes in outside air and supplies it to the exhaust path 7.

In order to prevent the ozone from leaking due to the backflow of the air, the ozone discharge prevention means 1 is provided on the suction side of the fan 16.
7 are connected. The ozone discharge prevention means 17 is for preventing ozone leakage when the fan 16 fails, and is an ozone-oxygen conversion catalyst for converting the passing ozone into oxygen. The ozone-oxygen conversion catalyst has a void through which air to which ozone is added passes. The void can be provided, for example, in a honeycomb shape with an ozone-oxygen conversion catalyst. The air passing through the gap of the ozone-oxygen conversion catalyst is
The ozone contained is converted to oxygen and discharged. Ozone-
Oxygen conversion catalysts include all catalysts that can convert ozone to oxygen, such as Nippon Shokubai Co., Ltd.
-1-1) "Ozone decomposition / deodorization catalyst (T
SO) ”can be used.

The ozone supply means 5A supplies the exhaust path 7 with air containing about 1 to 3 ppm of ozone. The ozone concentration supplied by the ozone supply means 5A to the exhaust path 7 is 0.3 to 1
It can be set in the range of 0 ppm. When the ozone concentration increases, it becomes impossible to completely convert the ozone concentration into oxygen by the catalyst 5C disposed on the discharge side of the exhaust path 7. If the ozone concentration is too low, the odor cannot be deodorized. The ozone concentration is set in the above range in consideration of the fact that the odor can be eliminated and the catalyst 5C can completely remove the ozone.

The exhaust path 7 is provided with a catalyst 5C on the discharge side of the stirring section 5B.
Is provided. The catalyst 5C converts the remaining ozone not consumed for the decomposition of the malodorous component into oxygen. The same catalyst as the ozone-oxygen conversion catalyst provided in the outside air suction passage can be used as the catalyst 5C provided here. The catalyst 5C also has a honeycomb shape for allowing the passage of air. The catalyst 5C decomposes residual ozone contained in the air passing therethrough into oxygen. If the catalyst used is, for example, “Ozone Decomposition / Deodorization Catalyst (TSO)” sold by Nippon Shokubai Co., Ltd. (Koraibashi 4-1-1, Chuo-ku, Osaka-shi), the ozone concentration is reduced, and at the same time, the malodorous component and ozone It also has the advantage of promoting the reaction with odor and adsorbing offensive odor components.

In the apparatus for treating fresh dust of the present invention, the deodorizing means 5 is not specified to use ozone. Deodorizing means 5 includes:
It is also possible to use a filter such as activated carbon that adsorbs odorous gas, or a catalyst that chemically changes odorous gas to deodorize it. These deodorizing means 5 are disposed in the exhaust path 7 as shown in FIG.

[0043]

The apparatus for treating garbage of the present invention can supply a sufficient amount of oxygen to the aerobic bacteria that inhabit the moisture absorbing member of the garbage decomposition chamber. In particular, in the apparatus of the present invention, the fresh dust decomposition chamber is separated into a suction side and an exhaust side by a separation partition, and the lower end of the separation partition is extended to the inside of the moisture absorbing member, or is brought close to the upper surface level of the moisture absorbing member. Therefore, the air sucked from the suction port does not pass through the exhaust path unlike the conventional device, but passes through the inside of the moisture absorbing member or is sprayed on the moisture absorbing member, so that the aerobic bacteria in the moisture absorbing member are removed. To supply oxygen efficiently. In addition, the apparatus for treating garbage of the present invention, in which a suction port is opened at a portion in contact with the moisture absorbing member and a gas permeable filter is stretched over the gas suction port, passes through the gas permeable filter and is sucked into the garbage decomposition chamber.

Further, the apparatus for treating fresh dust of the present invention comprises:
Since the inhaled air can be efficiently supplied to the moisture absorbing member, a large amount of oxygen can be supplied to the aerobic bacteria without increasing the amount of ventilation air. For this reason, the amount of air containing malodorous gas exhausted out of the apparatus from the processing device for fresh dust can be reduced. Therefore, there is a feature that the odor gas deodorizing means can be designed at a low cost and the odor gas can be sufficiently deodorized and exhausted. Even more advantageously, the supply of a sufficient amount of oxygen to the aerobic bacteria so that the aerobic bacteria efficiently decompose the raw dust also reduces the odor of the exhausted air.
