Description

TECHNICAL FIELD The present invention relates to an apparatus for deodorizing odorous components of air with a microorganism-retaining carrier.

At composting facilities, wastewater treatment facilities, and other facilities that generate malodorous odors in high concentrations, if the malodorous odors are released directly into the atmosphere, complaints are generated from nearby residents. Therefore, in order to harmonize with the local community, countermeasures against odors are indispensable. Conventionally, as a device for removing malodorous odors, a microorganism holding carrier is housed in a deodorizing tank, air containing malodorous air is sent into the deodorizing tank containing the microorganism holding carrier, and odors are generated by microorganisms living in the microorganism holding carrier. A deodorizing device that decomposes and deodorizes components is known (see, for example, Patent Documents 1 and 2).

Further, conventionally, there is known a deodorizing device in which the microorganism-retaining carrier is composed of a porous structure represented by lightweight cellular concrete (see, for example, Patent Document 3).

JP-A-2000-176239 JP-A-2005-7369 Japanese Patent Application Laid-Open No. 2011-56339

However, since lightweight aerated concrete is very expensive, the invention described in Patent Document 3 has a problem that the price of the apparatus becomes high and it is difficult to spread widely.

On the other hand, by constructing a deodorizing apparatus in which an inexpensive material such as a foam material is formed as a porous porous material, the porous material is used as a microorganism-retaining carrier, and the microorganism-retaining carrier is housed in a deodorizing tank, the conventional problem can be solved. can also be considered to solve Here, when dealing with a facility such as a large-sized plant that generates a large amount of foul odors, it is necessary to construct a large-sized deodorizing apparatus equipped with a large-sized deodorizing tank. However, when the size of the deodorizing tank is increased, a situation is likely to occur in which the air sent into the deodorizing tank only partially passes through the deodorizing tank. Therefore, in the inventions described in Patent Documents 1 to 3, in a large-sized apparatus having a large-sized deodorizing tank, the decomposition and deodorization of microorganisms in the microorganism-holding carrier in the portion through which air does not pass is not sufficiently exhibited, and the deodorizing effect is sufficient. The problem arises that the On the other hand, in a deodorizing device configured to spread the air throughout the deodorizing tank with a stirring device or the like that forcibly stirs the air inside the deodorizing tank, a large fan or a large electric motor that rotates the fan is provided. Since a stirring device is required, there is a problem that the cost of the entire deodorizing device rises.

It is characterized in that a diffusion path is formed as a flow path.

The invention according to claim 4 is characterized in that, in addition to the configuration according to claim 3 , the diffusion path is formed by a plurality of U-shaped grooves.

The invention according to claim 5 is, in addition to the configuration according to claim 3 or 4 , a substantially mesh-shaped fall prevention member for preventing the foam material from falling into the chamber part above the chamber part. is provided.

It is characterized by being arranged.

According to the invention of claim 1, the foaming material is provided adjacent to the upper side, the lower side, or the middle of the deodorizing section so as to close the upper surface, the lower surface, or the middle entire surface of the deodorizing section, and is filled with the foaming material. an airflow resistance portion having a higher airflow resistance than the deodorizing portion and formed as a fibrous airflow resistance layer having a predetermined thickness to increase the airflow resistance of the air flowing through the air flow path, the deodorizing portion, and/or the airflow resistance and a chamber part as a room for temporarily storing the air sent into the deodorizing tank provided adjacent to or in close proximity to the part, and the circulation of the air flowing through the air flow path is controlled by the ventilation resistance part. As a result of the increase, the air is sent to the deodorizing part in a state in which it spreads over substantially the entire surface of the deodorizing part in the chamber part. Since the air is sent to the deodorizing part in a diffused state, the odorous air tends to come into contact with the microorganism-holding carrier in the entire deodorizing part. Therefore, even if the air in the deodorizing tank is not forcibly agitated by an air agitator or the like, odors are decomposed and deodorized by microorganisms in the entire deodorizing section, and highly efficient deodorization can be performed. As a result, even with a large-scale apparatus having a large-sized deodorizing tank, it is possible to sufficiently exhibit the decomposition and deodorizing function while suppressing an increase in manufacturing costs.

Further, according to the first aspect of the invention, the ventilation resistance part is provided adjacent to the upper side, the lower side, or the middle of the deodorizing part so as to block the entire upper surface, the lower surface, or the middle of the deodorizing part. Airflow resistance is higher than that of the deodorizing part filled with the material, and as a result of being formed as a fibrous airflow resistance layer with a predetermined thickness, easy air circulation is hindered throughout the air flow path. The odor-laden air sent into the deodorizing tank is easily distributed throughout the deodorizing section, and the flow rate of the air flowing through the deodorizing tank is suppressed, so that the microorganism-holding carriers in the entire deodorizing section are exposed to the odorous air for a long period of time. can be contacted. Therefore, even in a large-scale apparatus having a large deodorizing tank, odor decomposition and deodorization can be efficiently performed by microorganisms in the entire deodorizing section, and a higher decomposition and deodorizing function can be exhibited.

According to the second aspect of the invention, the ventilation resistance part includes the shielding projection projecting inward from the wall surface of the inner peripheral part of the deodorizing tank in addition to the ventilation resistance layer. As a result, the odor-laden air sent into the deodorizing tank stays inside the deodorizing tank and spreads further throughout the deodorizing tank. easier. As a result, even a large-scale apparatus equipped with a large-sized deodorizing tank can exhibit a higher decomposition and deodorizing function while suppressing an increase in manufacturing costs.

According to the third aspect of the invention, the chamber part is provided below the deodorizing part in the deodorizing tank, the air flow path is configured to allow air to flow from the bottom to the top of the deodorizing tank, and the chamber part includes: An introduction section for introducing air into the chamber section is provided, and a diffusion path is formed as an air flow path for diffusing the air that has flowed in from the introduction section in the horizontal direction. , can be diffused horizontally in the chamber portion and sent to the deodorizing portion. This makes it easier for the odorous air to spread throughout the deodorizing tank. As a result, even a large-scale apparatus having a large-sized deodorizing tank 1 can exhibit a higher decomposition and deodorizing function while suppressing an increase in manufacturing costs.

According to the fourth aspect of the invention, the diffusion path is formed by a plurality of U-shaped grooves, so that the diffusion path can be constructed at a low cost, and the air sent from the introduction part can be transported in the chamber part. Horizontally diffusing structures can be easily constructed.

According to the fifth aspect of the invention, the upper side of the chamber portion is provided with a substantially mesh-shaped fall prevention member for preventing the foam material from falling into the chamber portion, thereby preventing the foam material from falling into the chamber portion. It is possible to reliably prevent a situation in which the air flow path in the chamber is blocked by the air flow path inside the chamber and the odorous air cannot reach the deodorizing tank with a simple structure.

According to the sixth aspect of the present invention, a water tank for storing the sprinkled water is provided below the deodorizing tank, and the water sprinkled to the deodorizing part can be used while being circulated. In addition, since the watering pipe is arranged along the deodorizing tank, the watering pipe that conducts the water to be sprayed is naturally warmed by the heat generated by the microorganisms in the deodorizing tank. Therefore, even when the microbial deodorizing apparatus is used in cold regions, it is possible to easily and reliably prevent freezing of the water passing through the watering pipe.

[Embodiment 1 of the invention]
Embodiment 1 of the present invention will be described below with reference to FIGS. 1 to 4. FIG.

[Installation mode of microbial deodorizing device]
As shown in FIG. 1, the microbial deodorizing apparatus 1A of Embodiment 1 is installed in a state of being connected to various facilities 100 via an exhaust pipe 200. As shown in FIG.

Various facilities 100 are devices, facilities, equipment, etc. that generate air containing bad odors. Specifically, for example, the various facilities 100 are composting facilities, wastewater treatment facilities, and the like that generate a high-concentration foul odor. can be anything. Various facilities 100 are assumed to be large-scale facilities or devices that emit a large amount of air accompanied by bad odors, but are not limited to this, and may be small-sized facilities or devices.

Exhaust pipe 200 is a pipe, tube, hose, or the like that is made of a material having pressure resistance and corrosion resistance, such as metal or vinyl chloride, and allows air to pass through the inside. In the middle of the exhaust pipe 200, an air blower 300 for forcibly sending air from the facility 100 side to the microbial deodorizing apparatus 1A side and a valve 400 for opening and closing the exhaust pipe 200 are provided.

[Configuration of microbial deodorizing device]
The microbial deodorizing device 1A shown in FIGS. 1 to 4 is formed as a large-sized device, for example, a substantially rectangular parallelepiped device having a size of about 10 meters long, 10 meters wide and 3 meters high. However, the microbial deodorizer 1A may have any size and shape as long as it can deodorize the air by holding the foam material 17 (described later) as a 'microorganism-holding carrier' inside.

As shown in FIGS. 3 and 4, it is conceivable that this microbial deodorizing device 1A is housed in a box-shaped housing portion 500 for use. The accommodation portion 500 accommodates an electric motor, electric cables, various wirings, various pipes, and the like for driving the microbial deodorizing apparatus 1A.

A microbial deodorizing apparatus 1A of Embodiment 1 shown in FIG. 1 includes a substantially rectangular parallelepiped deodorizing tank 1 . The deodorizing tank 1 can hold a foam material 17 (described later) inside, and is made of a material having high pressure resistance and corrosion resistance, such as metal, hard resin, and reinforced concrete.

As shown in FIG. 1, the deodorizing tank 1 is provided with a water tank 2, a chamber part 3, an airflow resistance layer 4 as an "airflow resistance part", and a deodorizing part 5 in this order from the bottom.

The water tank 2 is formed in the shape of a container whose circumference is sealed. Inside the water tank 2, water is stored for spraying a foam material 17 (described later). A pipe insertion hole 6 is formed in a part of the water tank 2, and a sprinkling pipe 7 is inserted through the pipe insertion hole 6 (sprinkling pipe 7 will be described later).

A microbubble generator 8 is provided inside the water tank 2 . The microbubble generator 8 functions to generate fine air bubbles in the water inside the water tank 2 .

The chamber part 3 is formed as a hollow room above the water tank 2 with the partition wall 9 interposed therebetween, and has a function of temporarily storing the air sent into the deodorizing tank 1 .

As shown in FIG. 3 , an insertion hole 10 as an “introduction portion” for introducing air into the chamber portion 3 is formed through a part of the chamber portion 3 . An exhaust pipe 200 is inserted to allow entrained air to enter.
Further, as shown in FIG. 3, inside the chamber part 3, a plurality of U-shaped grooves 11 formed of a highly rigid and corrosion-resistant material such as concrete or hard resin are arranged to form a flow path 12. forming. At a location near the exhaust pipe 200, the flow path 12 constitutes a diffusion path 13 for diffusing the air flowing into the chamber portion 3 from the exhaust pipe 200 in the horizontal direction (planar direction in FIG. 3).

Specifically, for example, as shown in FIG. are displaced in the horizontal direction (vertically displaced in FIG. 3). Similarly, the openings 11e, 11e of the second row U-shaped grooves 11b, 11b, the openings 11e, 11e of the third row U-shaped grooves 11c, 11c, and the openings of the third row U-shaped grooves 11c, 11c 11e, 11e and the openings 11e, 11e of the fourth row U-shaped grooves 11d, 11d are arranged in a horizontally shifted state. As a result, the air passing through the diffusion path 13 flows in the direction indicated by the arrows in FIG. However, the arrangement of the U-shaped grooves 11 in the diffusion path 13 may be other than that shown in FIG. Also, the diffusion path 13 may be made of a material other than that of the U-shaped groove 11 .

As shown in FIG. 2, a partition wall 3a is provided on the upper side of the chamber section 3. As shown in FIG. A ventilation hole portion 3b is formed in the partition wall 3a. Above the partition wall 3a, an installation projection 14 projects inward from the inner wall of the deodorizing tank 1, and a pallet 15 is arranged above the installation projection 14 as shown in FIG. The pallet 15 is formed of a material having high rigidity and corrosion resistance, such as hard resin, and is provided with a plurality of grid-like gaps 15a through which air flows.

As shown in FIG. 4 , a fall prevention member 16 is laid on the upper side of the pallet 15 . The fall prevention member 16 is made of a flexible and highly corrosion-resistant material, such as soft resin, and is formed in a substantially mesh shape. The size of the mesh of the drop prevention member 16 is formed to a size that allows air to circulate and holds most of the foam material 17 so as not to fall into the chamber portion 3, for example, a size of about 2 millimeters in diameter. However, the mesh of the fall prevention member 16 may have any size as long as it is large enough to prevent most of the foam material 17 from falling into the chamber portion 3 . 4 shows a state in which the anti-drop member 16 is arranged above only a part of the pallet 15 for the sake of simplification of illustration, but the anti-drop member 16 is actually placed above the pallet 15. cover the whole area.

By arranging the pallet 15 and the fall prevention member 16, the foam material 17 falls into the chamber part 3 while the air flowing into the chamber part 3 from the exhaust pipe 200 flows to the upper ventilation resistance layer 4 and the deodorizing part 5. can be prevented.

A ventilation resistance layer 4 is arranged above the pallet 15 and the fall prevention member 16 . The ventilation resistance layer 4 is made of a material having a higher ventilation resistance than the deodorizing section 5 in which the foam material 17 is arranged, such as rock wool 4a, and has a predetermined thickness (for example, several centimeters to several centimeters) over substantially the entire horizontal region. It is formed as a layer having a thickness of about 10 centimeters and covering substantially the entire surface of the deodorizing section 5 when viewed from the chamber section 3 side.

The airflow resistance layer 4 may be formed of any material or substance other than the rock wool 4a as long as the material or substance has high airflow resistance (for example, a nonwoven fabric or a nonwoven fabric-like substance). In addition, in this Embodiment 1, the ventilation resistance layer 4 is arranged in substantially the entire horizontal direction. They may be arranged in any shape. For example, the ventilation resistance layer 4 may be arranged in a part in the horizontal direction, for example, only in the substantially central part in plan view, only in the peripheral part in plan view, or only on the side where the exhaust pipe 200 is arranged in plan view, A ventilation resistance layer 4 may be provided on the upper side of the deodorizing section 5 .

As shown in FIGS. 1 and 2, in the first embodiment, the airflow resistance layer 4 is composed of a mixture of rock wool 4a and foam material 17 forming the deodorizing section 5. As shown in FIGS. This is to prevent the airflow resistance layer 4 formed only of rock wool 4a from becoming too large in airflow resistance due to aging. However, the ventilation resistance layer 4 may be configured in such a manner that the foam material 17 is not mixed.

As shown in FIGS. 1 and 2 , a deodorizing section 5 is provided above the airflow resistance layer 4 so as to be in contact with the airflow resistance layer 4 . The deodorizing part 5 is filled with a large number of foam materials 17 and formed into layers having a predetermined thickness (for example, a thickness of about 1 to 3 meters, but may be thicker or thinner). . Although FIGS. 1 and 2 show the foam material 17 only in part of the deodorizing section 5 for the sake of simplification, the foam material 17 is actually filled in substantially the entire area of the deodorizing section 5 .

Each foam material 17 constituting the deodorizing part 5 is porous with a diameter of, for example, about 5 millimeters to several tens of millimeters. The diameter of each pore (not shown) of the foam material 17 is about several micrometers to about several tens of micrometers. In the individual pores (not shown) of the foam material 17, microorganisms that have a deodorizing effect (microorganisms that biodegrade chemical substances that cause offensive odors (such as ammonia and hydrogen sulfide) (for example, nitrification that decomposes ammonia) bacteria, nitrifying bacteria, sulfur bacteria that decompose hydrogen sulfide, etc.) can live in large numbers.

Note that the foam material 17 of this embodiment is formed by firing and foaming recycled glass made mainly from glass bottles, for example, to have a surface area of about 80 square meters per gram. As a result, it is possible to form the foam material 17 at low cost, in which a large amount of microorganisms can live in a small volume and a high deodorizing effect can be obtained. Moreover, the foam material 17 has a structure with little ventilation resistance. As a result, the air supply resistance of the blower 300 can be prevented from becoming excessive, and the electricity cost for driving the blower 300 can be reduced.

The foam 17 of this embodiment is formed by firing recycled glass, as described above. By configuring the foam material 17 in this way, deterioration over time may occur due to corrosiveness to gases such as ammonia and hydrogen sulfide, as in the case where the foam material is formed of concrete (see [Patent Document 3] above). Also, it is possible to suppress the possibility of aging deterioration due to microbial decomposition as in the case where the foam material is formed of organic matter such as wood chips.

The foam material 17 is desirably made of a material that is inexpensive and has a large surface area. may be formed.

Located in the deodorizing section 5, the inner wall of the deodorizing tank 1 is provided with an airflow resistance projecting portion 18 as an "airflow resistance portion". The ventilation resistance protrusion 18 is provided in substantially the entire inner wall of the deodorizing tank 1 where the flow rate of air tends to increase inside the deodorizing tank 1 . However, the ventilation resistance protrusion 18 may be provided at any position and in any manner as long as it reduces the flow velocity of the air flowing upward through the deodorizing tank 1 . For example, the ventilation resistance protrusion 18 may be provided only in the vicinity of the position where the exhaust pipe 200 is provided in plan view.

An opening 19 is formed above the deodorizing section 5 of the deodorizing tank 1 . The inside of the deodorizing tank 1 forms an air flow path 20 through which air passes from the lower side (chamber portion 3) as "one side" to the upper side (opening portion 19) as "the other side". That is, in the air flow path 20 inside the deodorizing tank 1, air passes from the bottom to the top as indicated by the arrow in FIG. However, the "one side" and the "other side" of the air flow path 20 may be at any position. For example, the "one side" may be above the deodorizing tank 1 and the "other side" may be below the deodorizing tank 1, or the "one side" may be one side of the deodorizing tank 1 and the "other side" may be deodorizing. It may be on the other side of the tank 1 .

Further, the deodorizing tank 1 of Embodiment 1 is provided with a water sprinkling pipe 7 . The water sprinkling pipe 7 is arranged along the wall surface of the deodorizing tank 1 , especially along the deodorizing section 5 of the deodorizing tank 1 .

One end of the water sprinkling pipe 7 is arranged in the water tank 2 and the other end is arranged above the deodorizing tank 1 . Moreover, as shown in FIGS. 1 and 2, a pump 21 is provided in a part of the watering pipe 7 . The pump 21 functions to be driven by an electric motor (not shown), suck the water stored in the water tank 2 into the water pipe 7, and flow the water upward from the bottom of the water pipe 7. A water spray part 22 is provided on the other end side of the water spray pipe 7 . The water spraying part 22 is formed as a sprayer, and the water passed through the watering pipe 7 from the upper side of the deodorizing part 5 is atomized and dropped onto the deodorizing part 5 . However, the water sprinkling part 22 may be of any form as long as it is configured to drip water onto the deodorizing part 5. For example, the water sprinkling part 22 may be formed as one or a plurality of small holes opened in the water sprinkling pipe 7. You may

In addition, a net-like strainer 23 is provided in the watering pipe 7 . This strainer 23 has a function of filtering, removing and recovering the fine foam material 17 that flows inside the sprinkler pipe 7 together with the water.

[Usage mode of microbial deodorizing device]
Next, the mode of use of the microbial deodorizing apparatus 1A of this Embodiment 1 will be described.

In this Embodiment 1, when the valve 400 is opened, the air containing the malodor generated in the various facilities 100 is sent by the blower 300 through the exhaust pipe 200 into the chamber 3 of the microbial deodorizing apparatus 1A. On the upper side of the chamber part 3, there is a ventilation resistance layer 4 via a partition wall 3a having an opening formed with a ventilation hole part 3b. Since the upward flow is blocked, the air that has flowed into the chamber part 3 passes through the flow path 12 of the U-shaped groove 11 including the diffusion path 13 and diffuses in the chamber part 3 in the horizontal direction.

Then, the air diffused over the entire area of the chamber portion 3 passes through the ventilation hole portion 3b and flows upward. At this time, since the ventilation resistance of the ventilation resistance layer 4 is high, the flow of air is suppressed in the ventilation resistance layer 4, and the upward flow speed of the air becomes slow. As a result, the air slowly flows upward, passes through the ventilation resistance layer 4, reaches the deodorizing section 5, and then flows slowly upward in the deodorizing section 5 as well. Therefore, the residence time of the air in the deodorizing section 5 becomes longer, and a high deodorizing effect is exhibited.

When the air that has reached the deodorizing part 5 contacts the foaming material 17, the malodorous components contained in the air are decomposed by microorganisms that live and settle inside the foaming material 17, and the malodorous components are removed. Here, the air that has flowed into the chamber portion 3 from the exhaust pipe 200 diffuses over substantially the entire horizontal direction in the chamber portion 3, flows upward, and reaches the deodorizing portion 5. The foam material 17 is contacted over the entire area. That is, in the deodorizing section 5, air comes into contact with many foam materials 17, and a high deodorizing effect can be achieved.

Furthermore, in the deodorizing unit 5, the ventilation resistance protrusion 18 inhibits the flow of air over substantially the entire inner wall of the deodorizing tank 1 where air easily flows, so the flow velocity of the air increases near the inner wall of the deodorizing tank 1, deodorizing. Prevent situations where effectiveness is reduced. As a result, the air can flow slowly over substantially the entire area of the deodorizing section 5, and a high deodorizing effect can be achieved.

Then, the air that has passed through the deodorizing section 5 and whose malodorous components have been decomposed and deodorized by the microorganisms of the foam material 17 is discharged to the outside from the upper opening 19 of the deodorizing tank 1 . In this manner, the microbial deodorizing apparatus 1A of Embodiment 1 removes malodorous components from the air containing malodorous odors, and releases the deodorized air to the outside.

On the other hand, in the microbial deodorizing apparatus 1A of the first embodiment, the microbubble generator 8 generates fine air bubbles in the water inside the water tank 2, and the water containing the air bubbles flows into the sprinkler pipe 7.

The water that has flowed into the watering pipe 7 flows upward from below, and is watered inside the deodorizing tank 1 from the upper watering portion 22 . The sprinkled water is dripped inside the deodorizing tank 1 and used for growth of microorganisms living in the foam material 17 of the deodorizing section 5 and the airflow resistance layer 4 . Since the water sprinkled inside the deodorizing tank 1 contains fine air bubbles generated by the microbubble generator 8 inside the water tank 2 and contains a large amount of air, the inside of the foam material 17 and the water storage The growth and activity of microorganisms living in the water stored in the tank 2 can be promoted.

Further, the water dripped from the deodorizing part 5 and the airflow resistance layer 4 drips into the chamber part 3, further drips from the chamber part 3 into the water tank 2, and is stored in the water tank 2 again. Thus, water is circulated and used in the microorganism deodorizing apparatus 1A. The amount of water sprayed from the water sprayer 22 into the deodorizing tank 1 and the frequency of watering are desirably changed in accordance with the temperature and the like for the growth of microorganisms that settle and inhabit the foam material 17 . For example, in summer when the temperature is high, it is desirable to increase the number of times of watering from the watering part 22 into the deodorizing tank 1 and the amount of watering per time.

Here, since microorganisms inhabiting the foam material 17 generate heat when they are active, the deodorizing section 5 and the ventilation resistance layer 4 on which the foam material 17 is arranged are in a heated state. Since the water sprinkling pipe 7 is arranged along the wall surface of the deodorizing tank 1, the water flowing inside the water sprinkling pipe 7 is warmed by the heat emitted from the deodorizing part 5 and the ventilation resistance layer 4.例文帳に追加Therefore, even when the microbial deodorizing apparatus 1A is used in a cold region, freezing of the water passing through the inside of the watering pipe 7 can be suppressed.

Further, the fine foam material 17 existing in the deodorizing part 5 and the airflow resistance layer 4 drops into the water tank 2 and settles in the water tank 2 as the water drips. The fine foam material 17 that has settled in the water tank 2 is filtered and removed by the strainer 23 provided in the water sprinkling pipe 7 and collected.

[Effect]
As described above, in Embodiment 1, the airflow resistance layer 4 that increases the airflow resistance of the air flowing through the air flow path 20, the deodorizing section 5, and/or the airflow resistance layer 4 is provided adjacent to or in proximity to the airflow resistance layer 4, A chamber part 3 is provided as a room for temporarily storing the air sent into the deodorizing tank 1, and as a result of the ventilation resistance of the air flowing through the air flow path 20 being increased by the ventilation resistance layer 4, the air is In the chamber part 3, the air sent into the deodorizing part 5 is spread over substantially the entire surface of the deodorizing part 5, so that the air sent into the deodorizing tank 1 spreads over substantially the entire chamber part 3. The foamed material 17 in the entire area of the deodorizing unit 5 is likely to come into contact with the air accompanied by the odor. Therefore, even if the air in the deodorizing tank 1 is not forcibly agitated by an air agitator or the like, odors are decomposed and deodorized by microorganisms in the entire deodorizing section 5, and highly efficient deodorization can be performed. As a result, even with a large-scale apparatus having a large-sized deodorizing tank 1, it is possible to sufficiently exhibit the decomposition and deodorizing function while suppressing an increase in manufacturing costs.

In the first embodiment, the ventilation resistance layer 4 is formed as a ventilation resistance layer that faces the air flow direction in the air flow path 20 and closes substantially the entire surface of the air flow path 20. As a result of the obstruction of easy air circulation over the entire air flow path, the odor-laden air sent into the deodorizing tank 1 easily spreads throughout the deodorizing section 5, and the flow velocity of the air flowing through the deodorizing tank 1 is suppressed. Therefore, the foaming material 17 in the entire deodorizing section 5 can be brought into contact with the air accompanied by the odor for a long period of time. Therefore, even in a large-scale apparatus having a large-sized deodorizing tank 1, odors can be efficiently decomposed and deodorized by microorganisms in the entire deodorizing section 5. FIG.
