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. And an air conditioning system using the air purification device.

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.

[0003] In a conventional air purifying apparatus, odor components and harmful components are generally removed by using an adsorbing member containing an adsorbent such as activated carbon or zeolite. However, in this case, when the adsorbing member is saturated with the adsorbing substance, the air purification performance is greatly reduced, and the adsorbing member needs to be replaced periodically (for example, every several months). .

[0004] Therefore, there has been proposed an air purifying apparatus that regenerates the adsorbing member by oxidizing and decomposing odorous and harmful components adsorbed by the adsorbing member with a catalyst to deodorize or detoxify the odorous component or the harmful component (for example, Japanese Patent Laid-Open No. Hei 2 (1994)). -198614 (Japanese Patent No. 2892362). In this device, hot air is applied to the adsorbing member in a closed space to desorb odor components or harmful components from the adsorbing member, and air containing these desorbed components is circulated in the closed space. At the time of circulation, these components are oxidized and decomposed by a catalyst to make them odorless or harmless.

[0005]

When this method is used,
The advantage of eliminating the need to replace the adsorption member is obtained, but if the temperature decreases after the closed space is heated to regenerate the adsorption member, dew condensation occurs on the inner surface of the device, and mold and rust There has been a problem of causing the generation and, in some cases, water droplets leaking into the room.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to purify indoor air with an adsorbing member and to absorb odorous or harmful components adsorbed by the adsorbing member.

The suction rotor (11) has a part in the circumferential direction (for example, in the range of 20 ° to 180 °) covered from both sides.
A regeneration space (16), which is covered by (15) and covers a part of the suction rotor (11), is formed inside each cover (15).

Except that the second catalyst structure (21) is formed smaller than the catalyst structure (17) to be disposed in the discharge passage (19),
It is configured similarly to the catalyst structure (17).

-Operation- Next, the operation of the air purifier will be described.

In the first embodiment, during the air purification operation, the drive motor (14) is stopped, the blower (12) is started, and the suction rotor (11) is stopped while the suction rotor (11) is stopped. Allow room air to pass. Then, the indoor air is returned to the room as clean air after the odor component and the harmful component are adsorbed and purified by the adsorbent of the adsorption rotor (11).

In this state, when the air purification performance of the suction rotor (11) is reduced, the drive motor (14) is started and the suction rotor (11) is started.
(11) is rotated by a predetermined angle. Thus, the adsorption rotor (11) is positioned such that room air passes through a portion where the odor component and the harmful component have not yet been adsorbed. Therefore,
The air purification operation can be continued.

In order to perform the operation of rotating the suction rotor (11) by a predetermined angle, for example, a timer may be used to start the drive motor (14) when the air purification operation is performed for a predetermined time, or the suction may be performed. The concentration of odorous and harmful components in the air downstream of the rotor (11) is detected, and if the concentration exceeds a predetermined value, it is determined that the purification performance has decreased, and the drive motor (14) is started. You may. 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.

By repeating the above operation, the suction rotor (11)
When the odor component and the harmful component are adsorbed to almost the saturated state in all the parts, the adsorption rotor (11) is regenerated. Suction rotor
At the time of regeneration of (11), the electric heater (18) is energized to heat the adsorption rotor (11) and the catalyst structure (17). As a result, in the regeneration space (16), odor components and harmful components are desorbed from the adsorption rotor (11), and the catalyst is activated.
These desorbed components are oxidatively decomposed and deodorized or made harmless.

At this time, the fan (20) provided at the end of the discharge passage (19) rotates, and the air in the regeneration space (16) is discharged little by little. During regeneration of the adsorption rotor (11), the temperature in the regeneration space (16) becomes high, and the moisture contained in the adsorption rotor (11) evaporates. Dew condensation sometimes occurs in the apparatus, but when the air in the regeneration space (16) is discharged in this way, moisture is also discharged, so that dew condensation after cooling can be suppressed.

In addition, as the gas is discharged from the discharge passage (19), the regeneration space (16) enters the regeneration space (16) from the gap between the adsorption rotor (11) and the cover (15) or the adsorption rotor ( Air penetrates through 11) and is sucked, but the suction amount is very small, and the inside of the regeneration space (16) has a slight negative pressure. For this reason, the suction rotor (1
The desorption of odor components and harmful components from 1) is promoted, and odor leakage accompanying air leakage from the gap between the adsorption rotor (11) and the cover (15) hardly occurs.

The gas discharged from the discharge passage (19) passes through the second catalyst structure (17), and is discharged to the outside after the odor components and harmful components are decomposed.

According to the first embodiment, by periodically regenerating the adsorption rotor (11), the air purification performance is not reduced.
High purification performance can be maintained. In addition, mold spores and airborne bacteria also adhere to the adsorption rotor (11) at a considerable rate, but they can be killed by heating during regeneration of the adsorption rotor (11). The odor generated due to the cause can be suppressed.

Since the gas is exhausted from the regeneration space (16) when the adsorption rotor (11) is regenerated by heating, even if the device (1) is cooled to room temperature after the regeneration, the device ( 1) Prevents the formation of dew inside. As a result, mold and rust may occur in the device (1) due to condensation,
Water droplets can be prevented from leaking into the room.

Further, since gas is discharged at the time of regeneration to make the regeneration space (16) have a slight negative pressure, odor does not leak from between the adsorption rotor (11) and the cover (15). Moreover, since the second catalyst structure (21) is provided in the discharge passage (19), odor does not leak from the discharge passage (19).

Further, since the regeneration space (16) has a slight negative pressure, desorption of odorous and harmful components from the adsorption rotor (11) is promoted, and a slight air flow is generated in the regeneration space (16). Therefore, the decomposition performance is improved as compared with the closed state.

Modification of Embodiment 1 In the air purification device of the above embodiment, the air purification is performed in all parts of the adsorption rotor (11), and then the regeneration is collectively performed. The adsorption rotor (11) may be regenerated in another part (that is, in the regeneration space (16)) while purifying the air by using a part of (11). Then, it becomes possible to continue the air purification operation without interruption.

It is formed so as to cover a fan-shaped region having an acute angle (30 ° in the illustrated example). For this reason, the processing area for air purification except the regeneration space (16) is relatively large, whereas the regeneration area in the regeneration space (16) is formed as a small area. Also play space
As shown in FIG. 3, (16) is formed in a “U” -shaped space located across the suction rotor (11), and portions located on both sides of the suction rotor (16) communicate with each other. The suction rotor (11) has the same configuration as in the first embodiment.

The cover (15) is provided with an air suction port (15a) for introducing air into the reproduction space (16). The air that has flowed into the regeneration space (16) through the air suction port (15a) flows through the suction rotor (11) as shown by an arrow in FIG.
After passing round, the gas is discharged from the regeneration space (16) to the discharge passageway (19) through the discharge passageway (19) from the discharge port (15b), which is the inflow portion of the gas. For such an air flow, an exhaust fan (20) is provided at the end of the exhaust passage (19).

A filter (4) is arranged between the electric precipitator (2) and the air purifier (1) so as to remove dust and the like in the air. In addition, the air conditioner
(3) generates conditioned air from the air that has passed through the electrostatic precipitator (2), the filter (4), and the air purifier (1). Omitted.

-Operating operation- In the second embodiment, the indoor air is used to remove suspended matters such as dust from the air in the electric dust collector (2), and further removes tobacco tar and the like in the filter (4). After that, odor components and harmful components are removed in the air purification device (1). Then, the air passes through the air conditioner (3) to generate conditioned air, and clean air whose temperature and humidity are adjusted is supplied to the room.

In the air purification device (1), a fan-shaped cover (15)
Is set to an acute angle, and the regeneration space (16) is formed in a narrow area, and the area excluding the regeneration space (16) is formed in a wide area, so that air purification is performed using the wide area. .

On the other hand, in the regeneration space (16), the heater (18) is energized and the exhaust fan (20) is started to regenerate the suction rotor (11). At that time, the air sucked into the regeneration space (16) from the air suction port (15a) flows around the heat exchanger (22) to remove the heat of the exhaust gas, and
It is heated in (18) and passes through the suction rotor (11) along the current plate (23). As the high-temperature air passes through the adsorption rotor (11), the odor components and harmful components adsorbed by the adsorption rotor (11) from the indoor air are desorbed, and these components are removed together with the air into the regeneration space (16). Flows through.

The air containing the odorous and harmful components passes through the catalyst structure (11), and these components are deodorized or made harmless and flow into the outlet (15b). Then, after passing through the second catalyst structure (21), the above-mentioned components are again deodorized or made harmless, and then flow through the heat exchanger (21) to give heat to the suction air. Is discharged out of the machine through a discharge passage (19).

According to the second embodiment, the gas in the regeneration space (16) can be discharged to prevent dew condensation after regeneration, and the regeneration of the air purification device (1) can be prevented. A heat exchanger (22) is provided in the space (16),
Since the heat of the exhaust gas is given to the suction air,
Even if the capacity of the electric heater (18) is suppressed, deodorization of odorous components and harmful components from the adsorption rotor (11) and activation of the catalyst can be sufficiently performed, and energy saving can be achieved.

Since the flow of air is stabilized by providing the rectifying means (23) in the regeneration space (16), the suction rotor
(11) can be efficiently reproduced.

Since the cover (15) is fan-shaped and its apex angle is acute, of the total area of the suction rotor (16),
The area of the portion used for air purification can be increased. Therefore, even when the adsorption rotor (11) is regenerated while purifying the air, a decrease in the air purification performance can be suppressed.
