Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device provided with a deodorizing tank which can be rotated or inverted by at least 180 ° about a horizontal axis, and is not particularly limited, but particularly organic waste. The present invention relates to a deodorizing device suitable as a device for treating an offensive odor generated when a product is fermented and composted.

[0002]

2. Description of the Related Art Organic waste such as raw garbage discharged from kitchens at home, industrial cooking residues, food processing waste, and sewage discharged from barns are incinerated, but are not There are problems of incinerators, air pollution, auxiliary fuels, etc. From the viewpoint of effective utilization of organic waste, organic waste is also fermented in a fermenter and composted. By the way, when an organic waste is fermented and made into a compost, a malodorous gas such as methane gas, acetone, ammonia, and sulfur is generated. Therefore, a deodorizing device is attached to this type of fermenter. The deodorizing device is equipped with a deodorizing tank, and on the perforated plate provided therein, black soil, mullet soil,
Contains microbial culture material consisting of bark, fine-grained zeolite, etc. Therefore, when a malodorous gas to be treated is supplied from below or above the deodorization tank and passed through the microbial culture material, the malodorous components are biochemically separated due to microorganisms mainly growing in the culture material such as bacteria. It is deodorized by being understood by. Therefore, the deodorized gas can be released from the deodorizing tank into the atmosphere.

When deodorized as described above, the microbial culture material eventually dries. Since it becomes unsuitable for the growth environment of microorganisms when dried, it is necessary to replenish the microbial culture material with water every predetermined period, and in general, water is replenished from above.

[0004]

As described above, the deodorizing apparatus using microorganisms has excellent advantages such as low facility cost and low running cost simply by storing the microorganism culture material in the deodorizing tank. , There are some points to be improved. That is, in the conventional microbial culture material of the deodorizing tank, water necessary for the growth of microorganisms is sprinkled from above, but since the particle size of the microbial culture material is large and small, the microbial culture material with a small particle size is: It moves to the lower part of the deodorizing tank together with the flow of the sprinkled water, and a dense microbial culture material layer is formed at the lower part of the deodorizing tank. Since the lower part is dense, the upper part is a relatively rough layer. The lower dense microbial culture material layer has poor drainage, which creates an environment unsuitable for the growth of aerobic microorganisms, and also impedes the flow of gas to be treated and reduces the deodorizing function. On the other hand, the coarse microbial culture material layer on the upper part has a smaller surface area as the particle size of the culture material is larger, and the deodorizing function is similarly reduced.
Further, when different kinds of microorganism culture materials such as mulch and zeolite are mixed and used, they are similarly separated into upper and lower two layers due to a difference in specific gravity or a difference in shape. For the above-mentioned reasons, the conventional deodorizing device requires a manual operation or the like in which the microbial culture material having a two-layer structure is vertically replaced in order to maintain a predetermined deodorizing function. The present invention has been made in view of the above-mentioned conventional problems or drawbacks, and specifically, to provide a deodorizing device that always maintains a stable deodorizing function without relying on human hands. Has an aim.

The first and second water pipes 20a and 20b also enter into the support shaft 8'through a through hole formed in the hollow support shaft 8'and horizontally in the support shaft 8'to the left. It extends and goes outside. Then, the first and second three-way valves 21a and 21b are provided in the middle of the process and are connected to one of the common rotary joints 22. A water supply pipe 23 is connected to the other side of the rotary joint 22, and a water pump 24 is connected to the water supply pipe 23.
The water in the water tank 30 is sucked through the suction pipe 31. Drainage first and second three-way valve 21a, the one port of 21b, the drainage tube 32 a, 32 b are connected, these drainage pipes 32 a, 32 b, when the port is positioned below The hose 33 is adapted to be connected. A drainage pump 34 is provided in the drainage hose 33, and a discharge pipe 35 thereof is opened to the water tank 30.

Next, the operation of the first embodiment will be described. The side walls 7, 7 ′ of the deodorization tank 1 are opened, and the microbial culture material M made of black soil, mulch, bark, fine particle zeolite, or the like is placed in the third chamber 6. Also, the first
The first and second three-way valves 21a and 21b respectively installed in the second water pipes 20a and 20b are rotated by a predetermined angle from the state shown in FIG.
Close b. The first and second three-way valves 11a and 11b respectively installed in the first and second gas pipes 10a and 10b are switched to the state shown in FIG. In addition, the suction pipe 15 of the air pump 14 is connected to, for example, a fermenter that is a source of bad odor.

Then, the air pump 14 is started. Then, the malodorous gas generated by fermentation from the suction pipe 15 of the air pump 14 passes through the treated gas supply pipe 13, the rotary joint 12, the second three-way valve 11b, and the second gas pipe 10b, and is discharged from the deodorizing tank 1 of the deodorizing tank 1. 2 is supplied to the gas chamber 5. The supplied gas to be treated, which is a malodorous gas, is uniformly distributed by the perforated plate 3 and sent into the microorganism culture material M. When passing through the microorganism culture material M, it is deodorized by microorganisms growing in the microorganism culture material M in a known manner. The deodorized processing gas is collected in the first gas chamber 4 of the deodorization tank 1, and then discharged through the first gas pipe 10a to the atmosphere from the first three-way valve 11a.

After deodorizing for a predetermined period as described above, the microorganism culture material M is dried. Therefore, the first and second water pipes 2
The first and second three-way valves 21a and 21b of 0a and 20b are switched to the state shown in FIG. Then, the water pump 24 is started. Then, the water in the water tank 30 is supplied to the first gas chamber 4 of the deodorization tank 1 through the suction pipe 31, the water supply pipe 23, the rotary joint 22, and the first three-way valve 21a.
As a result, although not shown in the drawing, water is sprayed onto the microorganism culture material M from a water spray nozzle or the like. Excess water passes through the microorganism culture material M and falls into the second gas chamber 5. Excess water that has fallen into the second gas chamber 5 is activated by activating the drainage pump 34, whereby the second water pipe 20b, the second three-way valve 21b,
The drain pipe 32 b, the drain hose 33, and the discharge pipe 35 are returned to the water tank 30.

When the above deodorization and water sprinkling operations are repeated for a predetermined period, the microorganism culture material M is separated into upper and lower two layers due to differences in particle size, specific gravity, shape and the like. Therefore, the deodorization tank 1 is rotated or inverted by 180 ° around the horizontal axis. At this time, the second three-way valve 21 that is interposed in the second water pipe 20b.
The drain hose 33 is removed from the water distribution pipe 2b connected to the port b. After rotating 180 °, the drain hose 33 is connected to the water distribution pipe 32a of the first three-way valve 21a of the first water pipe 20a.

As a result, the two layers of the microorganism culture material M are also turned upside down, and the microorganism culture material M is gradually homogenized by a watering operation or the like. When rotated 180 °, the second gas chamber 5
Is located above and the first gas chamber 4 is located below, and with this, the first and second gas pipes 10, a10b
Also, since the first and second water pipes 20a and 20b are also turned upside down, it is clear that deodorization and water sprinkling can be performed as described above.

According to the first embodiment shown in FIG. 1, the drain hose 33 is provided to forcibly drain excess water, but the first and second water pipes 20a,
It is also possible to devise the gradient of 20b so as to drain directly from the first and second three-way valves 21a and 21b by gravity. At this time, it is clear that the water cannot be completely drained, and the deodorizing action is not hindered even if the water is partially accumulated at the bottom of the deodorizing tank 1.

Next, a second embodiment of the present invention will be described with reference to FIG. The structure of the deodorizing tank 1 is the same as the first
The embodiment is substantially the same as the embodiment described above, and the same reference numerals are given to the similar components and the duplicated description will not be given. According to the second embodiment, instead of the first and second gas pipes 10a and 10b, flexible first and second gas hoses 10a 'and 10b' having substantially the same length are applied, and the air pump 14 is used.
A directional control valve 40 is provided between and. Further, instead of the first and second water pipes 20a and 20b, similarly flexible first and second water hoses 20a 'and 20b' having substantially the same length.
The tandem center type switching valve 41 is provided between the water pump 24 and the water pump 24. In addition, the deodorization tank 1
Although rotated or inverted by 180 ° as in the first embodiment, the first and second gas hoses 10a ′, 10b ′ and the water hoses 20a ′, 20b ′ are made of flexible hoses and have substantially the same length. Since it has been selected, there is no problem in rotating or reversing the deodorizing tank 1.

It is apparent that the second embodiment operates in substantially the same manner. That is, when deodorizing, the tandem center type switching valve 41 is set to the C position. Then, the first and second water hoses 20a 'and 20b' are closed. Further, the direction switching valve 40 is set to the A position as shown in FIG. When the air pump 14 is started, the malodorous gas generated by fermentation from the suction pipe 15 of the air pump 14 flows from the direction switching valve 40 to the second gas hose 10b '.
And is supplied to the second gas chamber 5 of the deodorizing tank 1. Thereafter, the deodorization is performed in the same manner as in the first embodiment described above. The deodorized processing gas is collected in the first gas chamber 4 of the deodorization tank 1, and is then discharged from the direction switching valve 40 into the atmosphere through the first gas hose 10a '.

When water is sprinkled on the microorganism culture material M, the tandem center type switching valve 41 is set to the A position as shown in FIG. 2 and the water pump 24 is started. Then, the water in the water tank 30 is supplied from the suction pipe 31 through the switching valve 41 to the first gas chamber 4 of the deodorizing tank 1 by the first water hose 20a '. Thereby, the microorganism culture material M
Is also watered. Excess water that has fallen into the second gas chamber 5 is drained by gravity from the second water hose 20a ′ through the switching valve 41 to the water tank 30 by the drain pipe 35.

When the deodorizing tank 1 is rotated 180 ° about the horizontal axis or inverted, it is turned upside down. Therefore, the directional control valve 4
It is obvious that 0 can be switched to the B position to deodorize, and that the switching valve 41 can be switched to the B position to spray water. According to the present embodiment, the rotary joint 1
There is an advantage that 2, 22 are unnecessary and the drainage pipe system is simple.

As described above, according to the present invention, the inside of the deodorizing tank is the perforated plate, and the third space located between the first and second space portions and the first and second space portions. The microbial culture material consisting of black soil, mulch, bark, fine particle zeolite, etc. is placed in the third space, and the first and second spaces are treated gas pipes. Since one is used as a gas supply pipe to be treated and the other is used as a treated gas discharge pipe, the malodorous gas can be deodorized by microorganisms as in the conventional deodorizing device. Further, since the water pipe is opened in the first and second spaces, one can be used as a water supply pipe and the other can be used as a drain pipe to sprinkle water on the microorganism culture material. Moreover, according to the present invention, since the deodorizing tank is provided so as to be rotatable or reversible at least 180 ° about the horizontal axis, the microbial culture material is separated into layers by sprinkling, for example, and when the deodorizing function deteriorates, 18 deodorization tanks
By rotating or reversing by 0 °, the effect unique to the present invention that the deodorizing function can be restored without relying on human hands is obtained.
