Description

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 dust with bacteria and discarding it.

[0002]

2. Description of the Related Art An enormous amount of dust is generated in households nationwide. The daily amount of dust generated in each household is about 700g.
Is said. 70,000 tons of dust is generated in a city with 100,000 households a 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 it requires a large amount of energy to vaporize water. Therefore, the actual situation is that a huge amount of money is spent on the treatment of raw dust. The method of decomposing raw dust with bacteria instead of incineration does not have this adverse effect, and the energy consumed for disposal can be limited.

An apparatus for treating raw dust using bacteria is
If it is designed compactly, it can be installed in each home. If each household has this device, it is possible to decompose raw dust and dispose of it at home. Therefore, it is not necessary to collect raw dust and incinerate the raw dust. Each household does not even have to bring the dust to a specific place on the day of collection. This method
The huge cost of disposing of raw dust can be saved, and since the raw dust generated at home can be immediately treated, it has a very excellent feature that the raw dust can be treated conveniently and hygienically.

Devices for treating raw dust in this way have already been developed. In a conventional apparatus, a moisture absorbing member such as sawdust from cedar is placed in a raw dust decomposing chamber of a case, and bacteria and raw dust are put therein and stirred.
The device of this structure propagates bacteria to sawdust,
Raw dust, which is an organic substance, is decomposed into gas and water. Therefore, the amount of raw dust after treatment is reduced to a level that is not comparable to that before treatment. Therefore, raw dust may be added to the raw dust decomposition chamber every day, and bacteria may be added once every one to several days. The raw dust decomposed by bacteria is extremely reduced in volume and weight. For this reason, even if about 1 kg of raw dust is added every day, the weight of sawdust hardly increases. This is because raw dust is decomposed into gas and water, the gas is exhausted together with the air, and the water is vaporized and exhausted together with the air.

[0005]

The apparatus for decomposing raw dust in this manner has the feature that it can be used very conveniently.
This equipment requires ventilation of the dust decomposition chamber. This is because oxygen is supplied to aerobic bacteria that live in the raw dust decomposition chamber, and moisture and gas in which raw dust is decomposed are exhausted from the raw dust decomposition chamber. For this purpose, the raw dust treatment device is provided with an exhaust passage for discharging the air in the raw dust decomposition chamber. A fan is used to exhaust the air in the dust-decomposition chamber from the exhaust path to the outside of the machine. Fans
It is mainly provided in the exhaust passage. This fan sucks and exhausts the air in the dust decomposition chamber. Instead of being provided in the exhaust passage, a fan may be provided in a press-in passage for pressurizing air into the dust decomposition chamber. The press-fit path fan presses air into the dust decomposition chamber. The press-fitted air is discharged out of the machine through the exhaust passage.

As described above, in the device for exhausting the air in the dust decomposition chamber, it is necessary to deodorize the exhausted air and exhaust it to the outside of the machine. This is because the raw dust decomposition chamber decomposes raw dust into water and gas, and the gas generated by the decomposition contains malodorous gas. Unfortunately, even if the concentration of the malodorous gas is very low, when it is exhausted to the kitchen or the like, the malodorous odor is present. In order to prevent this harmful effect, it is necessary to provide a device for deodorizing the malodorous gas in the exhaust passage. For example, a deodorizing device that supplies ozone is connected to the exhaust passage. Ozone supplied to the exhaust passage oxidizes the malodorous gas to deodorize it. In an apparatus for deodorizing malodorous gas with ozone, it is necessary to lengthen the entire length of the exhaust passage in order to sufficiently mix ozone and malodorous gas for deodorization. Further, a structure that sufficiently mixes ozone and malodorous gas is required. Those that deodorize offensive odor gas in the exhaust passage are not specified as ozone. For example,
It can also be realized by disposing a member that adsorbs the malodorous gas. Even if the adsorption member is provided, it is necessary to increase the total length of the exhaust passage.

As described above, the apparatus for treating raw dust that exhausts deodorized air to the outside of the machine has a long exhaust passage. This is because the deodorizing device cannot be connected in a short exhaust passage. The long exhaust passage can extend the time for deodorizing the malodorous gas to more effectively deodorize the malodorous gas. However, in the long exhaust passage, foreign matters accumulate with the passage of time.
In particular, the device for agitating the moisture absorbing member and forcibly ventilating the raw dust decomposition chamber causes the moisture absorbing member to become powdery and discharged together with air to the exhaust passage. Therefore, a powdery moisture absorbing member or the like is accumulated in the exhaust passage.

The drawback of foreign matter accumulating in the exhaust passage can be reduced by increasing the capacity of the fan and increasing the flow velocity in the exhaust passage. This is because the air flowing at high speed blows out foreign matter such as the moisture absorbing member from the exhaust passage. However, if the air flow in the exhaust passage is increased, not only the power consumption of the fan is significantly increased, but also the malodorous gas cannot be effectively deodorized. This is because the time when the malodorous gas passes through the exhaust passage is shortened. In order to efficiently deodorize malodorous gas, it is important to reduce the flow velocity of air in the exhaust passage. The low-velocity air causes foreign substances to be mixed in the exhaust passage.

To make matters worse, when raw dust is decomposed,
A large amount of water is generated together with the gas. Moisture increases the relative humidity of the air discharged from the dust decomposition chamber.
When the high-humidity air is discharged from the exhaust passage, the foreign matter accumulated in the exhaust passage absorbs moisture, which solidifies over time and cannot be easily cleaned. further,
The relative humidity of the air passing through the exhaust passage fluctuates greatly, and when it is, it is extremely high, and when it is, not so high. This is because bacteria do not always break down raw dust at a constant rate. About 4 hours after the raw dust is supplied, the bacteria actively decompose the raw dust. In this state, the exhausted air contains a large amount of water. This is because raw dust is decomposed into water and discharged to the outside. Depending on the amount of raw dust added, if one day's raw dust is added, decomposition of raw dust will continue for 4 to 12 hours. During this time, the moisture content of the exhausted air becomes extremely high, and the relative humidity of the air becomes very high. However, when the decomposition of raw dust is completed, the amount of water generated is significantly reduced, and the humidity of the air becomes low. The foreign matter that accumulates in the exhaust passage absorbs moisture from the high-humidity air, and then becomes hard and hardens when the humidity of the air decreases. The absorbed moisture makes the foreign matter hard and strongly adheres to the inner surface of the exhaust passage. For this reason, with the passage of time, it becomes very difficult to remove the foreign substances accumulated in the exhaust passage.

The present invention was developed for the purpose of eliminating this drawback, and an important object of the present invention is to treat raw dust which can easily and easily remove foreign matter accumulated in the exhaust passage quickly. To provide the equipment.

[0011]

In order to achieve the above-mentioned object, an apparatus for treating raw dust of the present invention has the following constitution.
The apparatus for treating raw dust includes a raw dust decomposing chamber 2 for accommodating a moisture absorbing member 1 for adding bacteria for decomposing the raw dust, and the raw dust and the moisture absorbing member 1 disposed inside the raw dust decomposing chamber 2 and supplied. An agitation member 3 for agitating and the exhaust path 7 for exhausting air from the raw dust decomposition chamber 2 to the outside.

The exhaust passage 7 extends vertically. The vertical exhaust passage 7 has a suction port 10 for accumulating foreign matter, which opens downward. This suction port 10 is used for the dust decomposition chamber 2
As shown in FIG. 2, it is closed by an openable / closable lid 9 so that the air does not leak from here when exhausting the air. The air in the raw dust decomposition chamber 2 is exhausted from the exhaust passage 7 with the opening / closing lid 9 closed. When air is exhausted from the raw dust decomposition chamber 2 and foreign matter contained in the air is deposited on the bottom of the exhaust passage 7, the opening / closing lid 9 is opened to suck the foreign matter deposited in the exhaust passage 7 to the outside. Foreign matter in the exhaust passage 7 may be caused by connecting the suction port of the cleaner to the suction port 10,
Foreign matter deposited here can be easily removed.

Further, in the apparatus for treating raw dust according to the second aspect of the present invention, the exhaust passage 7 is arranged on the rear surface of the raw dust decomposition chamber 2. A suction port 10 is opened in the exhaust passage 7 via a suction pipe 11. The suction pipe 11 is arranged below the raw dust decomposition chamber 2, and the suction port 10 connected to the exhaust passage 7 is arranged on the front surface of the raw dust decomposition chamber 2.

[0014]

The apparatus for treating raw dust of the present invention performs the following operations to decompose raw dust. Bacteria are made to inhabit the hygroscopic member 1 such as sawdust that is filled in the raw dust decomposition chamber 2.
Bacteria decompose the supplied raw dust into gas and water. The water and gas decomposed from the raw dust pass through the exhaust passage 7 and are discharged from the raw dust decomposition chamber 2 to the outside.

The air discharged from the raw dust decomposition chamber 2 contains various foreign substances. For example, when sawdust or the like is used as the moisture absorbent member 1, the powdery material that is agitated is exhausted together with air. Foreign matter contained in the air
Accumulate in the exhaust passage 7. In particular, since it is difficult to increase the flow velocity of the air in the exhaust passage 7, it becomes an environment in which foreign matter is likely to accumulate.

The exhaust passage 7 extends vertically. Foreign matter accumulates on the bottom of the vertical exhaust passage 7. When foreign matter is accumulated in the exhaust passage 7, the opening / closing lid 9 of the suction port 10 is opened, and the suction port of the cleaner is connected to the foreign matter to be sucked and removed. At this time, preferably, the operation of the fan for ventilating the raw dust decomposition chamber 2 is stopped. However, the foreign matter in the exhaust passage 7 can be sucked out by the vacuum cleaner without stopping the operation of the fan. The reason is that the suction power of the vacuum cleaner is so strong that it cannot be compared with the blowing capacity of the fan.

After sucking the foreign matter in the exhaust passage 7 with a vacuum cleaner,
The suction port of the vacuum cleaner is removed from the suction port 10, and the suction port 10 is closed by the opening / closing lid 9 to perform normal operation. In this way, the apparatus for treating dust according to the present invention can easily remove the foreign matter in the exhaust passage 7 by opening the opening / closing lid 9 with a vacuum cleaner in this manner, so that the foreign matter is frequently discharged and firmly adheres to the exhaust passage 7. Can be discharged before. Particularly, as in the apparatus for treating raw dust according to claim 2 of the present invention, the one provided with the suction port 10 on the front face through the suction pipe 11 is convenient because foreign matter in the exhaust passage 7 can be removed more easily. There is a feature that can be used for.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. However, the examples shown below exemplify the raw dust processing apparatus for embodying the technical idea of the present invention, and the present invention does not specify the configuration of the raw dust processing apparatus to the following. .

And a catalyst 6 to be released to the outside.

The raw dust decomposition chamber 2 is provided inside a box-shaped case 8 having an opening at the top. The raw dust decomposition chamber 2 is provided with an opening / closing lid 15 in the upper opening for introducing raw dust. The opening / closing lid 15 is connected via a hinge so that it can be opened and closed. Open the open / close lid 15 and add fresh dust,
When the opening / closing lid 15 is closed, the odor of the raw dust decomposition chamber 2 does not leak.

The fresh dust decomposition chamber 2 is filled with sawdust as a moisture absorbing member 1. The sawdust has ideal physical properties as the moisture absorbent member 1. This is because it is a large amount of waste, is inexpensive, and has suitable hygroscopicity. Cedar sawdust is most suitable for sawdust. However, instead of sawdust, the hygroscopic member 1 may be made of any hygroscopic powder or granule that can inhabit bacteria.

Although only aerobic bacteria can be used as the bacteria added to the moisture absorbent member 1, facultative anaerobic bacteria are preferably added in addition to the aerobic bacteria. More preferably, enzymes are added in addition to bacteria. Examples of aerobic bacteria, facultative anaerobic bacteria and enzymes added to the moisture absorbent member 1 include ABC Japan Co., Ltd. (3-1, Kuramae, Taito-ku, Tokyo).
"Unizyme" which is a microorganism of 3-13) is used.
Unizyme is a bacterial powder in which aerobic bacteria, facultative anaerobes and enzymes are added to a hygroscopic powder.
Unizyme, which is a bacterial powder, can be used in a device that decomposes 2 kg of raw dust every day and can be added in a small amount of 5 g every 2 days.

The stirring member 3 is a spiral coil stirring blade 3A and a reduction motor 3 for rotating the stirring blade 3A.
B and. When the stirring blade 3A is rotated, the moisture absorbent member 1 is raised and stirred as indicated by the arrow. Since the stirring blade 3A is arranged in the central portion of the raw dust decomposing chamber 2, the hygroscopic member 1 is raised in the central portion of the raw dust decomposing chamber 2 and is circulated and agitated so as to descend around it.

An exhaust passage 7 is connected to the upper portion of the raw dust decomposition chamber 2. The exhaust path 7 exhausts air from the raw dust decomposition chamber 2. Along with the air, the moisture and gas from which raw dust is decomposed are discharged out of the machine. The gas discharged together with air contains a malodorous gas. A stirrer 12 is provided in the exhaust passage 7 in order to deodorize the malodorous gas with ozone and to remove moisture contained in the air by dew condensation. The stirring unit 12 is extended vertically and includes a plurality of baffle plates 13.
Is arranged. The exhaust passage 7 shown in the figure is provided with four rows of stirring portions 12 extending vertically, and the stirring portions 12 of each row are connected to the stirring portions 12 adjacent at the upper end and the lower end.

The baffle plate 13 of the agitating section 12 is fixed to the inner surface of the casing of the agitating section 12 while being in a downward slope toward the center of the agitating section 12. The baffle plate 13 shown in the figure has a rectangular shape, and the three sides of the baffle plate 13 on both sides and the rear edge are
It is fixed to the inner surface of the second casing. Baffle plate 1 shown
No. 3 is fixed to the casing at an angle of about 45 degrees with respect to the horizontal plane so that the condensed water can flow down smoothly. However, the inclination angle of the baffle plate 13 with respect to the horizontal plane may be in the range of 15 to 60 degrees.

The baffle plate 13 shown in the figure has a stirring section 1 so that air can flow in a jagged shape to stir more efficiently.
The front end portions of the baffle plates 13 disposed on both sides of 2 are further protruded from the center of the stirring unit 12 and are disposed in a state where they are vertically displaced from each other and overlap each other. Further, in the stirring units 12 in the second and fourth columns from the left, since air flows from the bottom to the top, the stirrer 12 has a feature that it is efficiently stirred at the tip portion of the baffle plate 13. This is because a vortex is likely to be generated on the upper surface of the baffle plate 13 which is leeward at the tip of the baffle plate 13.

Further, as shown in the figure, in the stirring section 12 which makes the air flow in a zigzag shape, the substantial total length of the passage becomes long, so that the air is stirred more efficiently and ozone and malodorous gas are mixed. It has the feature that it can be mixed efficiently.

Further, in the apparatus for treating raw dust shown in FIG. 1, an exhaust passage 7 is arranged on the back surface of the raw dust decomposition chamber 2.
At the lower end of the exhaust passage 7, there is provided a suction port 10 for sucking foreign matter accumulated there to the outside. The suction port 10 is the suction pipe 1
It is connected to the exhaust path 7 via 1. The suction pipe 11 is arranged below the raw dust decomposition chamber 2, and the suction port 10 connected to the exhaust passage 7 is arranged on the front surface of the raw dust decomposition chamber 2. In the apparatus for treating raw dust shown in FIG. 1, two suction pipes 11 are arranged below the raw dust decomposition chamber 2. The suction pipe 11 is a reduction motor 3B that rotates the stirring blade 3A.
It is arranged in a position that does not interfere with.

The suction port 10 prevents air from leaking from the exhaust port 10 when exhausting the air from the raw dust decomposition chamber 2.
As shown in FIG. 2, it is closed by an openable / closable lid 9. The opening / closing lid 9 closes the suction port 10 during normal use. When foreign matter accumulates on the bottom of the exhaust passage 7, the opening / closing lid 9
Is opened to suck out foreign matters accumulated in the exhaust passage 7 from the suction port 10 to the outside. Foreign matter in the exhaust passage 7 is easily removed, for example, by connecting the suction port of the cleaner to the suction port 10.

Since the raw dust decomposition chamber 2 shown in FIG. 1 is provided with four rows of exhaust passages 7 vertically, two suction ports 10 are provided through two suction pipes 11. Foreign substances that accumulate on the bottom of the exhaust passage 7 are sucked out from the respective suction ports 10.

Further, FIG. 3 is a sectional view of a raw dust processing apparatus having another structure as viewed from the front. In the apparatus for treating raw dust shown in this figure, the width of the lower portion of the raw dust decomposition chamber 2 is narrowed, a space is provided beside the raw dust decomposition chamber 2, and the suction pipe 11 is arranged therein. As in the apparatus shown in FIG. 1, the suction pipe 11 has a rear end connected to a lower portion of an exhaust passage 7 arranged on the back surface of the raw dust decomposition chamber 2 and a front end serving as a suction port 10. The suction port 10 is closed by the opening / closing lid 9 as in the device shown in FIG.

In this apparatus, two stirring blades 3A are arranged in the raw dust decomposition chamber 2. A stirring blade 3A of a screw shaft is horizontally arranged in a narrow portion below the raw dust decomposition chamber 2. Above the raw dust decomposition chamber 2, a stirring blade 3A having a horizontal rotating shaft with fixed blades is provided. The stirring blade 3A, which is a screw shaft disposed below the raw dust decomposition chamber 2, can stir the moisture absorbent member 1 and can also be used to discharge the moisture absorbent member 1 from the raw dust decomposition chamber 2. A device that uses a stirring blade that is a screw shaft as a discharge member of the moisture absorbing member 1 has a structure in which a discharge port (not shown) is opened in front of the screw shaft and the cover is closed. When the lid is opened and the stirring blade that is the screw shaft is rotated, the moisture absorbing member is discharged from the discharge port.

Further, in the apparatus shown in FIG. 1, a drain pipe 14 is connected to the bottom of the stirring section 12. The drain pipe 14 is bent in an inverted U shape to form a trap so that water is discharged and air is not discharged. The trap blocks the water that collects here and prevents the discharge of air. The device that connects the drain pipe 14 to the bottom of the stirring unit 12 has a feature that the dew condensation water can flow out of the exhaust passage 7, so that the moisture of the air passing therethrough can be efficiently removed.

However, it is not always necessary to connect a drain pipe to the stirring section 12. The agitator 12 without drainage pipe
Condensed water that adheres to the surface of the baffle plate 13 and flows down is collected at the bottom. The water accumulated here is vaporized into the air again and discharged when the relative humidity of the air becomes low. However, when the relative humidity of the air is high, the amount of water that accumulates at the bottom is vaporized into the air and is not immediately vaporized. Therefore, when the relative humidity of the air is high, the dew condensation on the baffle plate 13 separates the water and collects it on the bottom of the stirring section 12, and when the relative humidity of the air decreases, the water collecting on the bottom of the stirring section 12 vaporizes again. Is discharged together with the air. Even if the water that accumulates at the bottom of the stirring unit 12 is vaporized when the relative humidity of the air is low, the relative humidity of the original air is low, so the humidity does not become abnormally high. Therefore, dew does not condense on the air passing through the catalyst.

The exhaust passage 7 is provided with an exhaust fan 4 at the discharge end. The exhaust fan 4 forcibly exhausts the air in the raw dust decomposition chamber 2. When the air in the raw dust decomposition chamber 2 is forcedly exhausted by the exhaust fan 4, new air is sucked into the raw dust decomposition chamber 2 through the gap between the opening / closing lid 9 and the case. However, although not shown, the case may be provided with an opening for sucking outside air.

The exhaust passage 7 connects the ozone supply means 5 to the inflow side of the stirring section 12. The ozone supply means 5 sucks the outside air from the outside air suction path, adds ozone to the sucked air, and supplies the ozone to the inflow side of the agitation unit 12, which is the exhaust path 7. The ozone supply means 5 is, for example, one that applies a high voltage to opposing electrodes, discharges between the electrodes to allow air to pass therethrough, and converts part of oxygen contained in the air into ozone. The ozone supply means 5 shown in FIG. 1 includes a fan 16 for inhaling outside air. The fan 16 sucks outside air into the outside air suction passage and supplies it to the exhaust passage.

In order to prevent ozone from leaking from the outside air suction passage, ozone discharge prevention means 17 is connected to the outside air suction passage for sucking outside air. The ozone emission prevention means 17 is for preventing ozone leakage when the fan 16 fails, and is an ozone-oxygen conversion catalyst for converting passing ozone into oxygen. The ozone-oxygen conversion catalyst has voids through which air to which ozone is added passes. The voids may be provided, for example, in the form of a honeycomb with an ozone-oxygen conversion catalyst. Ozone contained in the air passing through the voids of the ozone-oxygen conversion catalyst is converted into oxygen and discharged. The ozone-oxygen conversion catalyst is any catalyst that can convert ozone into oxygen, for example, "Ozone decomposition / deodorization catalyst (TSO)" released by Nippon Shokubai Co., Ltd. (4-1-1 Koraibashi, Chuo-ku, Osaka City). Can be used.

The ozone supply means 5 supplies air containing ozone of about 1 to 3 ppm to the exhaust passage. Ozone supply means 5
Concentration of ozone supplied to the exhaust passage is 0.3 to 10 ppm
It can be set in the range of. When the ozone concentration becomes high, the catalyst provided on the exhaust side of the exhaust passage 7 cannot completely convert it to oxygen. If the ozone concentration is too low, the odor cannot be deodorized. The ozone concentration is set in the above range in consideration that the bad odor can be eliminated and ozone can be completely removed by the catalyst 6.

The exhaust path 7 is provided with the catalyst 6 on the discharge side of the stirring section 12. The catalyst 6 converts the ozone remaining without being consumed for the decomposition of the malodorous component into oxygen. As the catalyst arranged here, the same one as the ozone-oxygen conversion catalyst arranged in the outside air suction passage can be used. This catalyst 6 also has a honeycomb shape for passing air. The catalyst 6 decomposes residual ozone contained in the air passing therethrough into oxygen. Catalyst 6
For example, Nippon Shokubai Co., Ltd. (4 Koraibashi, Chuo-ku, Osaka City)
-1-1) released "Ozone decomposition / deodorization catalyst (T
The use of (SO) ”has the features of lowering the ozone concentration, promoting the reaction between the malodorous component and ozone, and adsorbing the malodorous component.
