Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifying apparatus for adsorbing odorous or harmful components in the air to be treated by an adsorbing member, and decomposing and oxidizing the adsorbed components with a catalyst to make them odorless or harmless. The present invention relates to an air conditioning system using the air purification device, and particularly relates to a measure for reducing the weight of an adsorption member.

[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 also used in general households, such as stores, medical institutions, factories, etc., 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. The adsorbing member has air permeability so that the air to be treated passes therethrough, and when the air to be treated passes, adsorbs odor components and harmful components to the adsorbent so that these components are removed from the air to be treated. Is configured.

In the apparatus described in the above publication, the adsorbing member is configured to be rotatable by a drive motor, a cover is provided to partially cover the adsorbing member, and a catalyst plate, a heater, Is arranged. 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, the odor component and the harmful component are desorbed from the adsorbing member, and these components are decomposed by the activated catalyst so as to be odorless or harmless.

[0005]

However, in the above configuration, since the adsorbing member is a solid material obtained by solidifying the adsorbent with a binder, there is a problem that the adsorbing member is relatively heavy and, for example, its driving method is limited. That is, when the output shaft of the drive motor is connected to the center of the suction member and driven, it is necessary to use a motor that can obtain a relatively large output torque such as a motor with a speed reducer, and does not use a high torque motor. In such a case, it was necessary to employ a system in which a belt is driven around the adsorbing member for driving. Due to such a limitation, the conventional apparatus has a low degree of freedom in design, and the accuracy of starting and stopping the suction member is not sufficient, and the cost tends to be high. In addition, since the suction member is heavy, it is necessary to increase the strength of the structural member of the apparatus, which causes a problem that the apparatus is large and the cost is high.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and an object of the present invention is to reduce the weight of an adsorbing member to increase the degree of freedom in device design.
An object of the present invention is to reduce the size and cost of the device.

[0007]

According to the present invention, the adsorbing member is constituted by a plate-like activated carbon fiber filter to reduce the weight and to make the apparatus compact and cost-effective.

Specifically, a solution taken by the present invention is an adsorbing member for adsorbing odorous or harmful components in the air to be treated.
(10), a regeneration means (18) for desorbing the odor component or the harmful component from the adsorption member (10) to regenerate the adsorption member (10), and deodorizing or detoxifying the odor component or the harmful component. Catalyst (19
a, 19b, 19c). The adsorbing member (10) is constituted by an activated carbon fiber filter formed in a plate shape. In the above configuration, the term “odor component or harmful component” is used not only when only one of them is targeted but also when both are targeted.

In the above structure, the adsorbing member (10) can be constituted by a plate-like filter in which zeolite is added to activated carbon fibers.

In the above structure, the suction member (10)
Are formed as a substantially disk-shaped suction rotor, a driving means (12) for rotating and driving the suction rotor (10), and a cover (15) covering a part of the suction rotor (10) and forming a regeneration chamber (16). ), And the reproducing means (18) can be disposed in the cover (15).

In the above configuration, the suction rotor (1
0) can be covered with a protective net (14), and the suction rotor (1

Further, in the above configuration, the suction rotor
It is preferable to provide a discharge passage (23) for discharging gas inside the regeneration chamber (16) at the time of regeneration of (10).

In the above structure, the catalyst for deodorizing or detoxifying odorous or harmful components is a catalyst structure (1).
9a, 19b, 19c), or the regeneration means is a suction member.
(10) may be constituted by a heater (18) for heating, and a layer of a catalyst for deodorizing or detoxifying odorous or harmful components may be formed on the surface of the heater (18). The catalyst structures (19a, 19b, 19c) may be, for example, those in which a catalyst layer is formed on the surface of a substrate.

The air conditioning system according to the present invention further includes a dust collecting device (3) for collecting dust floating in the air to be processed, from the upstream side to the downstream side of the air flow; And an air conditioner (4) that generates conditioned air from the air to be treated.

-Action- In the above solution, the air to be treated is purified by the adsorption of the odor component or the harmful component by the adsorption member (10). On the other hand, the odor component or the harmful component is adsorbed by the adsorbing member (1) by the regeneration means (18).
The adsorbing member (10) is regenerated by desorbing from the odor component (0), and the odor component or harmful component is deodorized or made harmless by the catalyst (19a, 19b, 19c). Since the adsorbing member (10) is constituted by an activated carbon fiber filter or a filter formed in a plate shape from activated carbon fibers to which zeolite is added, a conventional adsorbing member in which an adsorbent such as zeolite is solidified with a binder is used. The weight is sufficiently reduced as compared with.

The suction member (10) is formed as a substantially disk-shaped suction rotor, and a driving means (12) for rotating and driving the suction rotor (10) and a part of the suction rotor (10) are covered. Play room
When a cover (15) constituting (16) is provided and the regenerating means (18) is disposed inside the cover (15), the suction rotor (10)
While purifying the air at the part (adsorption part) outside of 5),
When the odor component and harmful component adhere to this adsorption part sufficiently,
The suction rotor (10) rotates and the suction portion is regenerated in the cover (15).

A protective net (14) is provided around the suction rotor (10).
If the suction rotor (10) is lightweight and the strength is weakened by providing a reinforcing frame (13) around the suction rotor (10), insufficient strength is compensated for.

Also, since the suction rotor (10) is lightweight,
Driving can be easily performed by connecting the drive motor (12) to the center of the suction rotor (10), and the stepping motor (12)
It is also possible to easily and accurately control the rotation angle by using.

When the suction rotor (10) is regenerated, the regeneration chamber (1)
If a discharge passage (23) for discharging gas inside 6) is provided, when steam is generated by heating the adsorption rotor (10) during regeneration, the steam is discharged from the regeneration chamber (16). If water vapor fills the regeneration chamber (16), condensation may occur in the regeneration chamber (16) after the device (1) has cooled to room temperature. Can be suppressed.

The catalyst comprises a catalyst structure (19a, 19b, 19c)
Even if a catalyst layer is formed on the surface of the heater (18), odor components and harmful components can be deodorized or made harmless.

[0022]

According to the above-mentioned means, the weight of the adsorbing member (10) can be sufficiently reduced as compared with the prior art, so that the structural members of the device (1) do not have to have an unnecessarily high strength. 1)
Size and cost can be reduced. In addition, if the suction member is constituted by the suction rotor (10), air can be purified by a portion (suction portion) outside the cover (15), but if the suction portion is contaminated with odorous or harmful components, the cover (15) is removed. Since it can be regenerated by the regenerating section (16) in the inside, it can be used without replacing the suction rotor (10).

Since the suction rotor (10) is light in weight, its driving is controlled by a driving motor located at the center of the suction rotor (10).
It is easy to connect (12) or select another method, and the degree of freedom in device design can be increased.
Even when the drive motor (12) is connected to the center of the suction rotor (12), the drive motor (12) does not need to be a particularly high-torque motor, and the rotation angle is controlled using a stepping motor (12). Can be performed easily and accurately.

A protective net (14) is provided around the suction rotor (10).
If the suction rotor (10) alone is insufficient in strength, it can compensate for the insufficient strength by providing a reinforcement frame (13) around the suction rotor (10). The problem that the suction rotor (10) is damaged can be suppressed.

When the suction rotor (10) is regenerated, the regeneration chamber (1)
By providing a discharge passage (23) for discharging the gas inside 6), it is possible to prevent dew condensation from occurring after regeneration of the adsorption rotor (10), so that rust due to the dew condensation and further mold generation may occur. The problem that an unpleasant odor is generated can also be prevented.

The catalyst comprises a catalyst structure (19a, 19b, 19c)
With this configuration, it is easy to form a shape suitable for the flow of air in the regeneration chamber (16) and make the contact area with air sufficiently large, and to form a catalyst layer on the surface of the heater (18). Then, downsizing can be achieved by reducing the installation space.

When the air purifying apparatus (1) having the above structure is used in the air conditioning system (2), the temperature of the room can be adjusted while keeping the air in the room clean.

The activated carbon fiber filter is a felt-shaped filter, and a suction filter (10) is formed by cutting a filter formed into an appropriate shape such as a rectangle into a disk shape. The adsorption rotor (10) is an aggregate of activated carbon fibers and has air permeability. However, in order to reduce air passage resistance during air purification, fine air holes ( (Not shown) may be formed in large numbers.

As described above, when an activated carbon fiber filter or an activated carbon fiber filter to which zeolite is added is used as the adsorption rotor (10), malodorous components such as ammonia, acetaldehyde, trimethylamine, and methyl mercaptan in room air, and carbon monoxide and formaldehyde are used. And other harmful components can be adsorbed and removed.

3a) are arranged and fixed so as to face each other, and the outer ends of the corresponding frame members (13a) are connected to each other by connecting members (13c). Note that the same material as the radially arranged framing members (13a) is used for each of the connecting members (13b, 13c). In addition, for simplification of the drawing, FIG.
Is shown only partially and the protection net (14) is omitted, and FIG.
Shows only a part of the protection network (14).

The suction rotor (10) is partially covered with a cover (15) on both sides in the circumferential direction. This 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 regeneration chamber (16) is provided on both sides of the suction rotor (10) via a communication chamber (17) located above the suction rotor (10).

In the illustrated example, the cover (15) is formed in a sector 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 (regeneration unit) is considerably smaller than the area of the part (adsorption part) located outside the regeneration chamber (16), but the center angle of the cover (15) is For example, 5 °
It is also possible to adjust the ratio between the reproducing section and the adsorbing section by changing the angle within a range of about 180 °.

An electric heater (regeneration means) (18) and a catalyst structure (19a, 19b, 19c) are provided in the cover (15). The electric heater (18) heats the adsorption rotor (10) to about 100 ° C. through the air in the regeneration chamber (16),
The odor component or the harmful component is desorbed from the adsorption rotor (10) to regenerate the adsorption rotor (10), and the catalyst structure (19a, 19b, 19c) is desorbed from the adsorption rotor (10). It is configured to deodorize or detoxify odor components or harmful components.

The electric heater (18) can have a large heat transfer area by, for example, integrating a large number of heat transfer fins with a 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 (18) is arranged. The electric heater (18) and the catalyst structure (19a)
Can be integrated with each other, in which case, for example, a catalyst layer may be formed on the surface of the heat transfer fin of the electric heater (18).

As shown in the figure, when a catalyst structure (19a) separate from the electric heater (18) is used, the catalyst structure (19a) is suitable for the flow of air in the regeneration chamber (16). When the catalyst layer is formed on the surface of the electric heater (18), it becomes easy to increase the contact area between the catalyst and the air by forming the catalyst in a deformed shape.

In the cover (15), there are provided seal passages (20) for passing outside air to the suction rotor (10) along both side edges of the regeneration chamber (16) (see FIG. 3). . Seal passage
(20) is constituted by narrow purging portions (20a, 20a) provided on both side edges of the regeneration chamber (16) facing each other with the suction rotor (10) interposed therebetween. Purge section (2
0a, 20a), one of which is on the outlet side and the other is on the suction side, and are respectively disposed in the regeneration chamber (16) with the shielding plate (21) therebetween. As shown in FIG. 1, each shielding plate (21) is formed such that its inner edge (21a) 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 (20a) are defined.

The purge section (20a) on the outlet side communicates with the outside air intake (22) shown in FIG. On the other hand, although the specific structure of the purge section (20a) on the suction side is not shown,
It communicates with the regeneration chamber (16) via a communication chamber (communication passage) (17) provided at the upper part of the cover (15). For this reason, the outside air sucked from the outside air intake (22) crosses the adsorption rotor (10) between the purge sections (20a) when flowing through the seal passage (20), and further flows through the communication chamber (17). Introduced into the regeneration room (16) through the.

In this embodiment, the heater (18) is arranged in the communication chamber (17), but may be arranged in the regeneration chamber (16). The catalyst structure (19a) disposed below the heater (18) in the communication chamber (17) and the catalyst structure disposed in front of the adsorption rotor (10) in the regeneration chamber (16). Body (19b)
May be appropriately changed in the installation location.

The cover (15) is provided with a discharge passage (23) communicating with the regeneration chamber (16) for discharging gas in the regeneration chamber (16) when the adsorption rotor (10) is regenerated. Have been. An exhaust fan (24) is provided at the end of the discharge passage (23). Further, a catalyst structure (19c) is disposed near the inflow port to the discharge passage (23) in order to more completely purify the exhaust gas. In addition, a drip-proof motor is used for the exhaust fan (24).

In the above configuration, when the exhaust fan (24) is driven, outside air is sucked into the seal passage (20) from the intake port (22) as shown in FIG. After passing through the heater (18) and the catalyst structure (19a) in the communication chamber (17) (not shown in FIG. 3), it is taken into the regeneration chamber (16). After passing through the catalyst structure (19b) and the adsorption rotor (10) in the regeneration chamber (16), this air is discharged from the catalyst structure (19c) to the outside through the discharge passage (23) (see FIG. 1 solid line arrow).

In this embodiment, the air purification is carried out by using a portion (adsorption portion) where the adsorption rotor (10) is out of the cover (15). Then, when the adsorption section has sufficiently adsorbed the odor component and the harmful component and has reached a substantially saturated state, the adsorption rotor (10) is rotated to perform regeneration in the regeneration chamber (16).

-Operation- Next, the operation of the air conditioning system (2) will be specifically described.

In this embodiment, during the air purification operation,
The blower of the air conditioner (4) is started with the drive motor (12) stopped and the suction rotor (10) stopped. Then, in the indoor air, after the suspended matter such as dust in the air is removed by the electric precipitator (3), the odor component and the harmful component are removed in the air purifier (1). Then, the air passes through the air conditioner (4) to generate conditioned air, and clean air whose temperature and humidity are adjusted is supplied to the room.

At this time, in the air purification device (1), the regeneration chamber (1)
6) Since the regenerating section located inside is formed in a narrow area and the adsorbing section located outside the regenerating chamber (16) is formed in a wide area, air purification is efficiently performed using the wide adsorbing section.

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 exhaust fan (24) and the electric heater ( Power is supplied to 18) to start the regeneration process of the suction rotor (10). When the regeneration of the portion in the regeneration chamber (16) is completed, the suction rotor (10) is rotated again by a predetermined angle to reproduce the next portion, and this partial regeneration is repeated several times to thereby rotate the adsorption rotor ( 10) Play the whole. At that time, since the suction rotor (10) is lightweight, the angle control at the time of starting and stopping can be accurately performed without requiring a high torque.

When the adsorption rotor (10) is regenerated, the electric heater (1
The flow of air when the discharge fan (24) is started by energizing 8) will be specifically described. First, outside air is sucked from the air intake (22) and flows through the seal passage (20).
In the seal passage (20), air is purged on the blow-out side (20a).
From the suction rotor (10) to the purge section (20
a). At this time, since the outside air passing through the adsorption rotor (10) is at room temperature, odor components and harmful components attached to the adsorption rotor (10) are not desorbed in the seal passage (20), and the outside air is already heated. It passes while absorbing heat from the suction rotor (10).

The air entering the purge section (20a) on the suction side flows into a communication chamber (17) provided in the upper portion of the cover (15), and is further heated by the electric heater (18) that has already generated heat. Is done. The hot air is supplied to each catalyst structure (19a, 19
b) and then through the suction rotor (10). As the high-temperature air passes through the adsorption rotor (10), odor components and harmful components are desorbed from the adsorption rotor (10) in the regeneration chamber (16), and the catalyst is activated. These components are oxidatively decomposed and deodorized or made harmless. The catalyst structure (19a, 19b) is attached to the adsorption rotor (1
Since the clean air is disposed on the upstream side of (0) so that the clean air passes through the adsorption rotor (10), odor components and the like are effectively desorbed.

When the processing gas passes through the adsorption rotor 10 in the regeneration chamber 16 from right to left in FIG. 1 (see the solid arrow), odorous components and harmful components are desorbed. Since the airflow flowing through the seal passage (20) acts as a shield at both side edges of (16), no odor leaks from the regeneration chamber (16) to the outside. Even if the processing gas flows out of the shielding plate (21), the gas is included in the airflow flowing through the seal passage (20) and flows again from the communication chamber (17) into the regeneration chamber (16). ,
Odor leakage and the like are prevented. Similarly, the heat of the processing gas is also absorbed by the air flowing from the communication chamber (17) to the regeneration chamber (16).

The processing gas after regenerating the adsorption rotor (10) is discharged from the discharge passage (23) to the outside of the machine by the exhaust fan (24). At that time, since the catalyst structure (19c) is also arranged in the inflow portion to the discharge passage (23), the processing gas is discharged to the outside as clean air in which odorous components and harmful components are decomposed. Become. Note that the catalyst structure (19c) may not necessarily be provided depending on the environment in which this device is installed.

-Effects of Embodiment- According to the present embodiment, by periodically regenerating the suction rotor (10), the air purification performance can be reduced without replacing the suction rotor (10). , High purification performance can be maintained. In addition, mold spores and airborne bacteria adhere to the adsorption rotor (10) at a considerable rate.However, since the adsorption rotor (10) can kill these by heating during regeneration, mold and the like are removed. The odor generated due to the cause can be suppressed.

In this embodiment, the electric dust collecting device (3)
The air conditioning system (2) is constructed by sequentially arranging the air purification device (1) and the air conditioning device (4), so that dust and the like floating in the air are removed and odor components and harmful components are removed. By generating the conditioned air after the removal, the room can be maintained in a very comfortable and clean state. Further, since the cover (15) is formed in a relatively narrow area and the area of a portion used for air purification is increased, sufficient air purification performance can be secured using the large area.

Since an activated carbon fiber filter or an activated carbon fiber filter to which zeolite is added is used for the adsorption rotor (10), it is much lighter in weight than a conventional adsorption rotor in which an adsorbent is solidified with a binder. Therefore, the structural members of the device (1) do not need to be strengthened more than necessary, and the size and cost of the device (1) can be reduced.

Furthermore, since the suction rotor (10) is lightweight, a high-torque motor is not required, and the rotation angle can be easily and accurately controlled using, for example, a stepping motor (12). Further, since the weight of the suction rotor (10) is reduced, the limitation on the driving method is reduced, and the degree of freedom in designing the device can be increased.

A reinforcing frame (13) is provided around the suction rotor (10).
And the protection net (14), the shortage of strength can be compensated for even if the suction rotor (10) is weakened in strength due to weight reduction. Therefore, it is possible to prevent the suction rotor (10) from being damaged by an external force or a driving force.

Further, when the adsorption rotor (10) is regenerated, the gas inside the regeneration chamber (16) is discharged from the discharge passage (23) while sucking the outside air from the intake port (22).
When steam is generated by heating the adsorption rotor (10) during regeneration, the steam is also discharged.As a result, even if the device (1) is cooled to room temperature after the regeneration, the device (1) The formation of dew inside can be prevented. For this reason,
It is possible to prevent mold and rust from occurring in the device (1) due to dew condensation, and to prevent water droplets from leaking into the room.

When the suction rotor (10) is regenerated, the regeneration chamber
By flowing outside air through the seal passages (20) provided on both side edges of (16), the airflow acts as a shield against odor leakage from the regeneration chamber (16).
Odor leakage can be sufficiently prevented even with a simple configuration that does not require a sealing material or the like, and cost increases can be suppressed by odor leakage countermeasures. It is to be noted that the fact that the adsorption rotor (10) is made of a relatively soft activated carbon fiber filter is particularly suitable for the non-contact sealing structure of the present embodiment using the seal passage (20).

-Variation of Embodiment- In the air purifying apparatus of the above-described embodiment, regeneration is performed collectively after all parts of the suction rotor (10) (parts outside the cover (15)) are subjected to air purification. The suction rotor
The air may be purified using a part of (10), and at the same time, the adsorption rotor (10) may be regenerated in another part (that is, in the regeneration chamber (16)). Then, for example, the suction rotor
In the case where the adsorbing section and the regenerating section in (10) are provided at a ratio of about 1: 1 or 2: 1 or the like, the air purifying operation can be easily continued without interruption.

In this case, 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, or the suction rotor (10) may be used. The concentration of odorous and harmful components in the air downstream of the adsorption section is detected, and when the concentration exceeds a predetermined value, it is determined that purification performance has decreased, and the drive motor (12) is started. Is also good. In the case of using a timer, for example, air purification may be performed during the time when a person is awake, and regeneration may be performed after going to bed, or adsorption and regeneration may be repeated several times a day. it can.
