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 purifier and an air conditioner 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 becomes saturated with the adsorbing component, 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.

Although not shown, instead of using the catalyst particles, for example, a catalyst structure in which a catalyst layer is formed on the surface of a honeycomb base material having a large surface area by forming a large number of hexagonal air passage holes. A body or the like can also be used.

The air purifier (1) is different from the air purifier (10) constructed as described above in that an electric dust collection unit (11) is provided upstream of the adsorption rotor (12) and a blower ( 13) are arranged outside the reproduction space (14). The electric dust collection unit (11) is configured to apply a charge to a floating substance such as dust in the air using corona discharge, and to collect the charged floating substance on an electrode. Then, after the indoor air is flown by the blower (13) in the order of the electric precipitating unit (11) and the adsorption rotor (12), the air is returned to the room. In addition, it is also possible to use a dust collection filter (not shown) in place of the electric dust collection unit (11) to make the apparatus simple.

-Operational Operation- Next, the operational operation of the air purifier (1) of the first embodiment will be described.

First, during normal operation for purifying indoor air, the blower (13) is started, and the indoor air passes through the electric dust collection unit (11) and the adsorption rotor (12), and then enters the room again. Be blown out. At this time, the indoor air is supplied to the electric dust collection unit (1
After dust and the like floating in the air after passing through 1) are removed, odor components and harmful components are removed through the purification passage (12a) of the adsorption rotor (12). Then, the clean air after passing through the suction rotor (12) is supplied into the room by the blower (13).

On the other hand, when the adsorbing rotor (12) adsorbs odor components and harmful components to a level close to the saturation state and the adsorbing performance is reduced, the adsorbing rotor (12) is regenerated. Suction rotor
In the regeneration of (12), the rotor (12) is rotated to move the portion to be processed into the regeneration space (14), and the heater (16) in the regeneration space (14) is energized, and Heat-resistant fan (17)
This is done by activating and circulating air. By circulating high-temperature air in the regeneration space (14) in this way, odor components and harmful components are desorbed from the adsorption rotor (12), and odor components and harmful components adhere to the adsorption rotor (12). To return to a state where no The portion thus regenerated can be moved out of the regeneration space (14) again and used for purifying indoor air.

On the other hand, the processing gas containing odorous components and harmful components circulating in the regeneration space (14) during regeneration is discharged from the regeneration space (14) by the exhaust fan (22) operating. (19) is sucked little by little. At this time, as the processing gas is sucked from the regeneration space (14) into the discharge passage (19), air is sucked into the regeneration space (14) from the suction valve (23), but the suction amount is very small. Then, the inside of the reproduction space (14) becomes slightly negative pressure. For this reason, desorption of odor components and harmful components from the adsorption rotor (12) is promoted, and air leakage from the regeneration space (14) and associated odor leakage are less likely to occur.

During regeneration of the adsorption rotor (12), the temperature in the regeneration space (14) becomes high, and the moisture contained in the adsorption rotor (12) and the like evaporates. When the temperature becomes low later, dew condensation occurs in the device. In the first embodiment, as the air in the regeneration space (14) is discharged to the outside from the discharge passage (19), moisture is also discharged together. So
Dew condensation after cooling can be suppressed.

In the disassembly section (20) of the discharge passage (19), the catalyst (20)
a) is heated by the electric heater (21) and activated. Therefore, when the processing gas sucked from the regeneration space (14) to the discharge passage (19) passes through the decomposition section (20), the odor component or the harmful component contained in the processing gas is deodorized or made harmless. You. Then, the odorless and harmless processed gas on which the odor component and the harmful component have been processed in this way is further sucked by the exhaust fan (22) and discharged outside the machine.

-Effects of First Embodiment- According to the first embodiment, the following effects are exhibited.

That is, in this air purifier (1), while the odor components and harmful components in the indoor air are adsorbed and removed by the adsorption rotor (12), when the purification performance of the adsorption rotor (12) is reduced, the adsorption rotor (12) is used. 12) can be played. Therefore, by periodically regenerating the suction rotor (12),
Even without replacing (12), high purification performance can be maintained without lowering the air purification performance.

Further, while circulating the processing gas heated to a high temperature in the regeneration space (14) during regeneration of the adsorption rotor (12),
Discharge little by little from the regeneration space (14) and
4) Since the outside air is introduced little by little into the inside, even if the heater (16) and the fan (17) in the playback space (14) are stopped and the inside of the playback space (14) is cooled down to room temperature, , Playback space (14)
It is possible to prevent condensation from forming on the cover (15) and the like. Therefore, mold and rust may occur in the device due to condensation,
Water droplets can be prevented from leaking into the room.

Also, since gas is discharged at the time of regeneration so that the regeneration space (14) has a slightly negative pressure, odor may leak from between the adsorption rotor (12) and the cover (15). Absent. Furthermore, since the regeneration space (14) becomes slightly negative pressure,
The desorption of odor components and harmful components from the adsorption rotor (12) is promoted, and a slight air flow is generated in the regeneration space (14), so that the decomposition performance is improved as compared with the closed state.

Mold spores and airborne bacteria also adhere to the adsorption rotor (12) at a considerable rate.
Since these can be killed by heating at the time of regeneration of (12), the odor generated due to mold or the like can be suppressed.

Further, since the processing gas is sucked from the regeneration space (14) to the discharge passage (19) and then processed by the catalyst (20a) and then exhausted, the odor component and the harmful component are discharged as it is. Never.

Further, a discharge passage (1) is provided around the regeneration space (14).
Since the catalyst (20a) is filled in the discharge passage (19) by providing the exhaust passage (19), the catalyst (20a) can be preheated by utilizing the heat in the regeneration space (14), and the heat loss can be suppressed. Can be. If the catalyst (20a) can be sufficiently heated only by the heater (16) in the regeneration space (14), the heater (21) for the catalyst (20a) does not necessarily need to be turned on. Efficient operation is possible.

Further, a desorption process is performed in the reproduction space (14),
Since the decomposition process is performed in the discharge passage (19),
Since the temperature and flow rate suitable for desorption and the temperature and flow rate suitable for decomposition can be set separately, more efficient operation can be performed.

Modification of Embodiment 1 In the above embodiment, when the suction rotor (12) purifies the indoor air, the heater (16) and the heat-resistant fan in the regeneration chamber (14) are used.
(17) may be stopped so as not to perform regeneration, or the heater (16) and the heat-resistant fan (17) may be activated to operate the suction rotor.
The regeneration of (12) may be performed simultaneously with the air purification.

When the air purification and the regeneration of the adsorption rotor (12) are performed separately, the adsorption rotor (12) can be intermittently rotated, and the air can be purified after all the parts have been purified. . When purifying indoor air and regenerating the adsorption rotor (12) simultaneously, the purification may be performed with the adsorption rotor (12) stopped, or the adsorption rotor (12) may be continuously and slowly rotated. Alternatively, it may be performed while rotating the lens at a predetermined timing intermittently at a predetermined angle.

When the adsorption rotor (12) is intermittently regenerated, for example, the concentration of the odor component or the harmful component on the downstream side of the adsorption rotor (12) is always detected by a sensor and becomes higher than a predetermined concentration. In this case, the reproduction may be started, or the reproduction may be repeated at predetermined time intervals using a timer or the like. 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.
