Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a process for adsorbing odorous or harmful components in air to be treated by an adsorbing member.
The present invention relates to an air purification device that oxidizes and decomposes these adsorbed components at high temperature with a catalyst to deodorize or detoxify the air.
The present invention relates to a technique for preventing a decrease in adsorption performance.

[0002]

2. Description of the Related Art Conventionally, air purifiers have been used to measure odor components and harmful components such as tobacco odor, food odor, human urine odor, body odor, pet odor, perm odor, architectural odor, oily smoke, VOC and NOx. It is used in stores, medical institutions, factories, and the like to remove odors.

In a conventional air purifying apparatus, for example,
As described in Japanese Patent Publication No. 0-277365, an adsorbing member in which an adsorbent such as zeolite is solidified with a binder and formed into a disk shape or the like is used. This adsorbing member has air permeability so that the air to be processed passes therethrough, and removes these components from the air to be processed by adsorbing odor components and harmful components to the adsorbent when the air to be processed passes. It is configured as follows.

In the apparatus described in the above publication, the disk-shaped suction member is configured to be rotatable by a drive motor,
A cover that covers a part of the adsorption member is provided, and a catalyst plate and a heater are disposed in the cover as desorption and regeneration means. Then, while purifying the air to be treated in a portion (adsorbing portion) exposed outside the cover, when the adsorbing portion sufficiently adsorbs odorous components and harmful components, the adsorbing member is rotated to move the adsorbing portion inside the cover. Heat. Thus, while the odorous component and the harmful component are desorbed from the adsorbing member, these components are decomposed by the activated catalyst to make the component odorless or harmless.

[0005]

However, after a certain period of time has passed using the air purifying device, floating substances such as dust in the air to be treated adhere to the surface of the adsorption member, and the dirt gradually decreases. It will be accumulated. For this reason, ventilation resistance of an adsorption member may become large and the adsorption performance of a device may fall. On the other hand, it is possible to provide a mechanism for removing dirt on the surface of the adsorption member in the air purification device, but in that case, the device configuration may be complicated and the cost may be increased.

[0006] The present invention has been made in view of the above problems, and an object of the present invention is to reduce the adsorbing performance while suppressing the complication of the configuration of the air purification device and the increase in cost. To prevent it.

[0007]

The present invention focuses on the fact that a photocatalyst has a function of decomposing dirt, and decomposes and removes dirt by including a photocatalyst in an adsorption member.

More specifically, a first solution of the present invention is to provide an adsorbing member (10) containing an adsorbent for adsorbing odorous or harmful components in the air to be treated, and an adsorbing member (10). A regeneration chamber (16) serving as a space for partially regenerating, and a heating means (24) such as a heater for desorbing odorous or harmful components from the adsorption member (10) in the regeneration chamber (16) are desorbed. It is assumed that the air purifying apparatus includes a thermal catalyst (25) for oxidizing and decomposing odorous or harmful components. A light emitting unit (14) for irradiating the suction member (10) with light is provided, and the suction member (10) is provided.
However, at least the surface contains a photocatalyst activated by irradiation with light from the light emitting means (14).

[0009] The second solution taken by the present invention is:
In the first solution, the adsorbing member (10) contains the photocatalyst at a ratio of 2% to 20% with respect to the adsorbent. In addition, as a more preferable ratio, the photocatalyst can be set to about 5% with respect to the adsorbent.

[0010] A third solution taken by the present invention is:
In the first or second solution, the suction member (10)
A cover (15) that covers a part of the cover (15) is provided, a regeneration chamber (16) is formed in the cover (15), and the light emitting means (14) is arranged outside the cover (15).

[0011] A fourth solution taken by the present invention is:
In any one of the first to third solving means, the suction member is constituted as a substantially disk-shaped suction rotor (10), and a driving means (12) for rotating the suction rotor (10) is provided. Things.

In the first solution, when the adsorbing member (10) sufficiently adsorbs odorous or harmful components in the air to be treated, the adsorbing member (10) is regenerated in the regeneration chamber (16). Perform playback. In the regeneration chamber (16), the adsorbing member (10) is heated by a heater or the like provided as a heating means (24), and odor components and harmful components are desorbed from the adsorbing member (10). Also, the suction member
The odor components and harmful components desorbed from (10) are oxidatively decomposed by activating the thermal catalyst (25), and the air containing the odor components and harmful components is deodorized or made harmless. Then, the air after the treatment may be discharged from the regeneration chamber (16) to the outside of the apparatus.

In the first solution, the suction member
Since (10) contains a photocatalyst, when light is emitted from the light emitting means (14) to the adsorption member (10), the photocatalyst is activated, and the dirt attached to the surface of the adsorption member (10) is decomposed and removed. Is done. The activated photocatalyst also has a function of decomposing odor components and harmful components adsorbed on the surface of the adsorption member (10) to make it odorless or harmless.

In the second solution, the ratio of the photocatalyst to the adsorbent is specified.
When an excessive amount of the photocatalyst is contained, the amount of the adsorbent decreases and the adsorptivity decreases, whereas such a decrease in the adsorptivity can be suppressed. As the photocatalyst, for example, TiO ₂
However, since such a photocatalyst itself has an adsorbing property to some extent, as long as the content of the photocatalyst is not excessive, a decomposition action can be exhibited while suppressing a decrease in the adsorbing ability.

[0015] In the third solution, regeneration of the adsorbing member (10) by desorption of odorous and harmful components is performed in the regeneration chamber (1).
On the other hand, the decomposition of dirt by the photocatalyst and the like are performed outside the regeneration chamber (16).

In the fourth solution, the light emitting means
If the suction rotor (10) is arranged, for example, along the radial direction of the suction rotor (10), the light emitting means (1) is used when the suction rotor (10) rotates.
When 4) emits light, the entire suction rotor (10) can be irradiated with light during at least one rotation of the suction rotor (10), so that the entire surface of the suction rotor (10) can be decomposed and removed.

[0017]

According to the first means, the adsorbing member (10) having adsorbed odor components and harmful components is regenerated by the heating means (24), and these desorbed components are converted to the heat catalyst ( While decomposing in step 25), the photocatalyst can decompose and remove dirt on the surface of the adsorption member (10). Therefore, even if time passes, the surface of the suction member (10) is hardly stained, so the suction member (10)
This prevents the ventilation resistance of the device from becoming large, thereby preventing the adsorption performance of the device from being reduced. Further, since the dirt is decomposed and removed by using a photocatalyst, a mechanism for removing the dirt by mechanical movement is not required, so that the complexity of the apparatus configuration and the increase in cost can be suppressed.

Further, according to the second solution, the ratio between the adsorbent and the photocatalyst contained in the adsorbing member (10) is specified in an appropriate range, so that the adsorbing performance of the adsorbing member (10) and the contamination are reduced. At a high level in a well-balanced manner.

Further, according to the third solution, a light emitting means (14) for removing dirt from the adsorbing member (10) is provided outside the regeneration chamber (16) for regenerating the adsorbing member (10). Odor components and harmful components adsorbed by the adsorbing member (10) are surely desorbed and decomposed in the regeneration chamber (16), and at the same time, the contamination of the adsorbing member (10) outside the regeneration chamber (16). Can be decomposed and removed.

Further, according to the fourth solution, the light emitting means (14) is set to one by rotating the suction rotor (10).
Even when the suction rotor (10) makes one round, it is possible to irradiate the entire suction rotor (10) with light even if the suction rotor (10) makes one round. Therefore, in the air purifying device of the type in which the adsorbing member (10) is stationary, a large number of light emitting means are required to irradiate the entirety of the adsorbing member (10) with light. It is not necessary to provide a means.

A rotating shaft (10a) fixed to the center of the suction rotor (10) is rotatably held at the upper end of the stand member (11b) via a bearing unit (not shown).

A motor (12) is fixed to the base (11a) as driving means for driving the suction rotor (10) to rotate. A drive pulley (12a) is connected to the motor (12) via a speed reduction mechanism (not shown), and a drive belt (13) is hung between the drive pulley (12a) and the suction rotor (10). Then, by driving the motor (12), the suction rotor (1

The adsorption rotor (10) is formed into a disc shape by solidifying an adsorbent such as zeolite and a photocatalyst such as TiO ₂ with a binder. The ratio of the photocatalyst to the adsorbent is 2 to 20%.
Preferably, it is set to be about 5%. The suction rotor (10) is formed into a honeycomb shape, for example, and has air permeability so that air to be processed passes in the thickness direction. Then, the adsorption rotor (10) removes these components from the air to be treated by adsorbing odor components and harmful components to the adsorbent when the air to be treated passes. Specifically, the adsorption rotor (10) can adsorb and remove malodorous components such as ammonia, acetaldehyde, trimethylamine, and methyl mercaptan and harmful components such as carbon monoxide and formaldehyde in the air.

The photocatalyst is activated by irradiating light to decompose odorous and harmful components adsorbed on the surface of the adsorption rotor (10), and to float dust and the like in the air to be treated. It is possible to decompose and remove dirt generated by the substances adhering to the surface of the suction rotor (10). To irradiate the photocatalyst with light, a black light lamp (14) is fixed to the frame (11) as a light emitting means. The black light lamp (14) mainly emits ultraviolet radiation of about 360 nm and emits almost no visible radiation, and a high-pressure mercury lamp or a fluorescent lamp is used. This black light lamp (14)

On the other hand, the suction rotor (10) is partially covered with a cover (15) from both sides in the circumferential direction, and the cover (15) is covered with the black light lamp (14) with the rotating shaft (10a) interposed therebetween. ) (At a position vertically above the rotation axis (10a)). The cover (15) is fixed to a stand member (11b) of the frame (11), and a regeneration chamber (16) is defined inside the cover (15). The reproduction room (16)

It is provided over both surfaces of the suction rotor (10).

In the illustrated example, the cover (15) is formed in a fan shape having a small center angle, and the suction rotor (10) is moved to the regeneration chamber (1).
6) The area of the part located inside (hereinafter referred to as the playback unit)
Although the area is considerably smaller than the area of the part located outside the regeneration chamber (16) (hereinafter referred to as the adsorption part),
It is also possible to change the center angle of (15) within a range of, for example, about 5 ° to 180 ° to adjust the ratio between the reproducing unit and the suction unit.

In the cover (15), there are provided seal passages (18) for passing outside air to the suction rotor (10) along both side edges of the regeneration chamber (16). As shown in FIG. 3, which is a schematic air flow diagram, the seal passage (18) has a regeneration chamber (16).
Narrow purge sections (18a, 18a) provided on both side edges of
Are arranged to face each other with the suction rotor (10) interposed therebetween. One of the opposing purge units (18a, 18a) is on the outlet side and the other is on the suction side, and each is disposed in the regeneration chamber (16) with a shielding plate (19) therebetween. As shown in FIG. 1, each shielding plate (19) is formed so that its inner edge (19a) is located with a slight gap from the surface of the suction rotor (10), and The internal space and the internal space of the purge section (18a) are partitioned.

The purge section (18a) on the blow side communicates with an air introduction passage (21) provided with a regenerative blower (20).
On the other hand, although the specific structure of the purge section (18a) on the suction side is not shown, the communication chamber (1) provided above the cover (15) is not shown.
It communicates with the regeneration room (16) via 7). In addition, the reproduction room (1
6) communicates with the air discharge passage (22). For this reason, the outside air sent to the air introduction passage (21) crosses the adsorption rotor (10) between the two purge sections (18a) when flowing through the seal passage (18), and further from the communication chamber (17). After being introduced into the regeneration chamber (16), it is discharged from the air discharge passage (22). Then, the air introduction passage (21), the seal passage (18), the communication room (17), the regeneration room (1
6) and the entire space in the cover (15) including the air discharge passage (22) constitutes a regeneration air passage (23).

In the cover (15), an electric heater (24) and a catalyst structure (25) are provided. The electric heater (24) is provided in the communication chamber (17), and is located in the regeneration air passage (23) on the upstream side of the regeneration position of the adsorption rotor (10). Also,
The catalyst structure (25) is located in the air discharge passage (22).
In the above configuration, the adsorption rotor (10) is heated by the electric heater (24) via the air flowing through the regeneration air passage (23), and the odor component or the harmful component is desorbed from the adsorption rotor (10) and the adsorption is performed. The rotor (10) is regenerated. Then, the catalyst structure (25) is heated by high-temperature air containing odor components and harmful components desorbed from the adsorption rotor (10), thereby deodorizing or detoxifying these odor components or harmful components. .

The catalyst structure (25) is not shown in detail.
Not shown, for example, by forming a large number of hexagonal air passage holes

In addition, the electric heater (24) may have a large heat transfer area by integrating a large number of heat transfer fins with, for example, a bar-shaped heating element. The specific shape and structure of the heating element may be appropriately set according to the shape of the portion where the electric heater (24) is disposed, and specifically, for example, a sheath heater, a semiconductor heater, a ceramic heater, or the like may be used. it can. In this embodiment, the electric heater
(24) is provided only in one place, but a heater is also arranged near the upstream side of the air with respect to the catalyst structure (25), and the adsorbing member is provided.
The heater (24) for regeneration of (10) and a heater (not shown) for heating the catalyst may be provided separately. In that case, if a catalyst layer is formed on the surface of the catalyst heating heater, the catalyst heating heater and the catalyst structure (25) can be integrated.

In the above configuration, when the regenerative blower (20) is driven, the outside air is blown from the air introduction passage (21) to the seal passage (18) as shown in FIG. 1 and FIG. Then, after passing through the electric heater (24) in the communication chamber (17), the air flows into the regeneration chamber (16). This air passes through the adsorption rotor (10) in the regeneration chamber (16), passes through the air discharge passage (22), passes through the catalyst structure (25), and is discharged to the outside (solid line in FIG. 1). Arrow airflow).

In the present embodiment, the air purification is performed by using a portion (adsorption portion) where the adsorption rotor (10) is out of the cover (15). When the adsorbing section has sufficiently adsorbed odorous and harmful components to reach a substantially saturated state, the regeneration chamber (1)
Play within 6).

This air purification device (1) is installed in a factory or the like, and as shown in FIG. 4, is connected to a plurality of machines (M) that generate odor or harmful gas in the factory by a duct (D). The exhaust gas of the machine (M) is sucked from the duct (D) and deodorized or made harmless by the adsorption rotor (10). And, by adopting a system that sucks in the duct (D) before the odor components and harmful components generated in each machine (M) diffuse into a wide space, it is possible to use multiple air purification devices even in a wide place without using multiple air purification devices. It can be processed by one air purification device (1).

This air purifying device (1) is installed in a commercial building, a medical institution, etc. in addition to a factory, and is connected to a plurality of rooms by ducts to remove odorous and harmful components in the air in each room. May be used to remove. Also, this air purification device
(1) can be used to remove odorous and harmful components in each zone by connecting ducts to the ceiling of multiple zones with strong odors in a large indoor space of recreational facilities such as pachinko amusement arcades. Good.

-Operating operation- Next, the operating operation of the air purification device (1) will be specifically described.

First, during the air purification operation, the drive motor (12)
Are started, and the blowers (2, 20) are started with the suction rotor (10) being rotated. Then, this air purification device
In (1), the regeneration section located inside the regeneration chamber (16) is formed in a narrow area, and the adsorption section located outside the regeneration chamber (16) is formed in a wide area. It is used efficiently to remove odorous and harmful components from the air to be treated. In addition, these odor components and harmful components are adsorbed to some extent by not only the adsorbent but also the photocatalyst.

At this time, the electric heater (2
Power is also supplied to 4), and the regeneration process is performed at the same time. The flow of air during regeneration of the adsorption rotor (10) will be specifically described. First, outside air flows from the air introduction passage (21) through the seal passage (18). In the seal passage (18), the air flows from the purge section (18a) on the blowing side across the suction rotor (10) into the purge section (18a) on the suction side. At this time, the suction rotor
Since the air passing through (10) is at room temperature, the seal passage (18)
Then, the odor component and the harmful component attached to the adsorption rotor (10) are not desorbed, and the outside air passes while absorbing heat from the already heated adsorption rotor (10).

The air entering the purge section (18a) on the suction side flows into the communication chamber (17) provided at the upper part in the cover (15), and is further heated by the electric heater (24) that has already generated heat. Is done. The hot air passes through the suction rotor (10). As the high-temperature air passes through the adsorption rotor (10), the adsorption rotor (10)
Odorous and harmful components are desorbed from water. These desorbed components are contained in the regeneration air and flow through the air discharge passage (22). At this time, since the catalyst is activated by the flow of high-temperature air, these components desorbed from the adsorption rotor (10) are oxidatively decomposed and deodorized or made harmless.

In the present embodiment, when air passes from the right to the left in FIG. 1 through the adsorption rotor (10) in the regeneration chamber (16) (see the solid arrow), odor components and harmful components are desorbed. In addition, since the airflow (see the dashed arrow) flowing through the seal passage (18) acts as a shield at both side edges of the regeneration chamber (16), no odor leaks from the regeneration chamber (16) to the outside. Even if air containing odor components etc. flows out of the shielding plate (19), the air is included in the airflow flowing through the seal passage (18) and returns from the communication chamber (17) to the regeneration chamber (16). Will flow in,
Odor leakage to the outside is prevented. Similarly, the heat of the high-temperature air is also absorbed by the air flowing from the communication chamber (17) to the regeneration chamber (16). Then, the air after regenerating the adsorption rotor (10) passes through the catalyst structure (25), and is converted into clean air in which odor components and harmful components are decomposed.
2) Released outside the aircraft.

On the other hand, during the operation of the air purification device (1), the black light lamp (14) emits light, and the light is applied to the adsorption rotor (10) outside the cover (15). For this reason, the suction rotor (1
The photocatalyst is activated on the surface of (0), and the adsorption rotor (10)
The odorous and harmful components adsorbed on the surface are decomposed to some extent. In addition, when the air to be treated passes through the adsorption rotor (10), floating substances such as dust in the air adhere to the surface of the adsorption rotor (10) and become dirty, but the photocatalyst is activated. This dirt is decomposed and removed. Therefore, the surface of the suction rotor (10) is maintained in a clean state for a long time.

-Effects of Embodiment- As described above, according to the present embodiment, almost no dirt adheres to the surface of the suction rotor (10). Can be prevented from increasing. Therefore, the adsorption performance of the device (1) can be maintained for a long time. Further, since there is no need to provide a mechanism for removing dirt on the surface of the suction rotor (10) by mechanical movement, it is possible to prevent the apparatus configuration from becoming complicated and the cost from increasing.

Further, according to the present embodiment, the suction rotor
By performing the regeneration of (10), even if the adsorption rotor (10) is not replaced, the air purification performance does not decrease and high purification performance can be maintained. Mold spores and airborne bacteria also adhere to the adsorption rotor (10) at a considerable rate, but they can be killed by heating during regeneration of the adsorption rotor (10). Odors caused by the cause can also be suppressed.

In this embodiment, since the cover (15) is formed in a relatively narrow area and the area of the suction portion used for air purification is increased, sufficient air purification performance can be obtained by using the large area. Can be secured. Then, while purifying the air using a part of the suction rotor (10) (that is, the suction part outside the cover (15)), the other part (that is, the reproduction part in the regeneration chamber (16)) at the same time. Since the suction rotor (10) is regenerated, the air purification operation can be continued for a long time without interruption, in combination with the fact that the surface of the suction rotor (10) is free from dirt.

-Modification of Embodiment- <Modification 1> In the above embodiment, as shown in FIG. 5, for example, the air flowing through the air introduction passage (21) and the air discharge passage A heat exchanger (26) for exchanging heat with air discharged from (22) may be provided. As the heat exchanger (26), for example, a spiral tube heat exchanger with a radiation fin, a double tube heat exchanger, or the like can be used.

With this configuration, the outside air is heated by the heat of the processed air discharged when first passing through the heat exchanger (26). The outside air is not heated to such an extent that the odor components and the like of the adsorption rotor (10) are desorbed by this heat, and passes through the adsorption rotor (10) when flowing through the seal passages (18) on both sides of the regeneration chamber (16). Only. afterwards,
The air is heated to a high temperature by the electric heater (24) when passing through the communication chamber (17) as in the embodiment, and enters the regeneration chamber (16). Therefore, odor components and harmful components are desorbed from the adsorption rotor (10) by the high-temperature air.

Thereafter, the air becomes clean air from the regeneration chamber (16) through the air discharge passage (22), and passes through the heat exchanger (26) when discharged outside. Therefore, the air after the treatment is cooled by applying heat to the air introduced from the outside and then discharged outside the machine.

Therefore, the air can be efficiently heated even if the capacity of the electric heater (24) is suppressed, and the deodorization of odorous and harmful components from the adsorption rotor (10) and the activation of the catalyst can be sufficiently performed. As a result, energy saving can be achieved.

<Modification 2> In the above embodiment, the suction fan (2) and the regeneration fan (20) are used separately. However, as shown in FIG. 6, a regeneration fan is used. Instead, a part (about 10% of the whole) of the purified air after purification may be used for regeneration of the adsorption rotor (10). Specifically, in the illustrated example, a branch duct (31) is connected to a duct (30) for introducing purified air into a room, and the branch duct (31)
A damper (32) is provided in the apparatus, so that the air can be supplied to the reproducing unit while adjusting the flow rate of the air for reproduction.

In this way, the number of blowers used in the device (1) can be reduced, and the possibility of failure is reduced, so that the reliability of the device (1) can be improved. Also, in order to use the purified air after purification for regeneration, the adsorption rotor (1
0) has an advantage that odor components and the like are easily desorbed.

<Modification 3> The air purification device of the above embodiment
In (1), the adsorption rotor (10) is always rotated to perform air purification and regeneration simultaneously and continuously.However, the regeneration is performed by intermittently rotating the adsorption rotor (10) during air purification. It may be.

Specifically, for example, a timer may be used to start the drive motor (12) and rotate the suction rotor (10) by a predetermined angle when the air purification operation is performed for a predetermined time,
The concentration of odor components and harmful components in the air downstream of the adsorption section of the adsorption rotor (10) is detected, and when the concentration exceeds a predetermined value, it is determined that the purification performance has decreased, and the drive motor (12) is activated. You may make it start. In addition, for example, when using a timer, perform air purification during the activity time of the person during the day,
Reproduction can be performed when no one is present at night, or adsorption and reproduction can be repeated several times a day. Even in this case, it is possible to continue the air purification operation without interruption.

As another operation method, the suction rotor (1
After performing the air purification using the entirety of (0), the regeneration may be performed collectively. In this case, during the air purification operation, the blower (2) is started with the drive motor (12) stopped and the suction rotor (10) stopped. Then, the odor component and the harmful component are removed from the room air using the wide suction portion located outside the cover (15).

On the other hand, if the air purification performance of the suction rotor (10) decreases in this state, the drive motor (12) is started to rotate the suction rotor (10) by a predetermined angle, and the regeneration blower (20) and the electric heater Power is supplied to (24) to start the regeneration process of the suction rotor (10). And when the reproduction of the part in the reproduction room (16) ends,
The suction rotor (10) is rotated again by a predetermined angle to reproduce the next part, and this partial reproduction may be repeated several times to reproduce the entire suction rotor (10).

In this case, the regeneration of the adsorption rotor (10) is performed by discharging the air inside the regeneration chamber (16) from the air discharge passage (22) while introducing outside air from the air introduction passage (21). If steam is generated by heating the adsorption rotor (10) during regeneration, the steam is also discharged. Therefore, even if the device (1) is cooled to room temperature after the regeneration,
The formation of dew inside can be prevented. Therefore, there is an advantage that it is possible to prevent mold and rust from being generated in the device (1) due to the dew condensation, and to prevent water droplets from leaking into the room.
