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 which adsorbs odorous or harmful components in air with an adsorbing member and oxidizes and decomposes the adsorbed components with a catalyst to make them odorless or harmless. The present invention relates to an air purifier and an air conditioner using the air purification device.

[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.

[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.

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 purpose of the present invention is to prevent the occurrence of dew condensation after the regeneration of the adsorbing member in an air purification apparatus of the type in which odor is decomposed or detoxified by oxidizing and decomposing it with a catalyst.

According to 6), these components are desorbed from the adsorbing member (12) that has adsorbed odorous or harmful components in the air, and these components are oxidized and decomposed by the oxidation catalyst (19a) to become odorless or harmless. . On the other hand, the processing gas in the regeneration space (14) can be replaced with the outside air little by little during regeneration by the ventilation means (20, 23, 24, 25), or can be replaced together with the outside air after the regeneration is completed. . For this reason,

[0020]

According to the above-mentioned solution, although the regeneration of the adsorbing member (12) and the deodorization or detoxification of odorous and harmful components are performed while circulating the processing gas in the regeneration space (14), Since the processing gas in the regeneration space (14) can be ventilated to the outside air to discharge moisture, it is possible to prevent the inside of the regeneration space (14) from becoming humid due to heating during regeneration. For this reason, dew condensation after cooling the device can be prevented, so that mold and rust may occur,
Water droplets can be prevented from leaking into the room. Further, since the adsorbing member (12) can be regenerated, high air purification performance can be maintained without replacing the adsorbing member (12).

A body or the like can also be used. Furthermore, it is also possible to form a catalyst layer on the surface of the heat transfer fins of the heater (16), so that the decomposition means (19) and the desorption means (16) can be integrated.

In the air purifying device (10), for the purpose of replacing the air in the regeneration space (14), a discharge passage (20) communicating with the regeneration space (14) is discharged so as to exhaust the processing gas in the regeneration space (14). ) And an introduction passage (24) also communicating with the reproduction space (14) so as to introduce air into the reproduction space (14). At the end of the discharge passage (20), an exhaust fan (23) for sucking and discharging air from the regeneration space (14) is provided, and the discharge passage (20) and the exhaust fan (23) constitute discharging means. Have been. Further, the introduction passage (24) is provided with an introduction valve (25) between the regeneration space (14) and the opposite end is opened as an outside air introduction port, and the introduction passage (24) and the introduction valve (25 ) Constitute the introduction means. The discharge means (20, 23) and the introduction means (24, 25) constitute a ventilation means.

The air purifier (10) has a double-tube heat exchange means as a heat exchange means for exchanging heat between the introduced air passing through the introduction passage (24) and the exhaust air passing through the discharge passage (20). A vessel (heat exchange means) (26) is provided. Specifically, the passage between the inner tube and the outer tube of the double tube heat exchanger (26) is configured as an introduction passage (24), while the inside of the inner tube is defined as a discharge passage (20).
The exhaust gas and the introduced air exchange heat.

On the other hand, in the exhaust passage (20), when the exhaust gas contains odorous components and harmful components, these components are located at a position in front of the double tube heat exchanger (26). An auxiliary decomposition section (21) is provided to decompose to make it odorless or harmless.
The auxiliary decomposition section (21) is composed of a large number of particulate oxidation catalysts (21a), like the decomposition section (19). Outside the discharge passage (20), an auxiliary electric heater (22) is disposed as a heating means for heating and activating the oxidation catalyst particles (21a) of the auxiliary decomposition section (21).

Further, between the cover (15) of the regeneration space (14) and the adsorption rotor (12), even when the temperature of the regeneration space (14) is high and the air expands, odor leakage or the like is generated. In order to prevent this, a sealing mechanism (not shown) is provided.

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.

-Operation- Next, the operation of the air purifier (1) of the present 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)
Is activated to circulate high-temperature air in the reproduction space (14). 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. In addition, reproduction space (14)
By circulating the high-temperature processing gas in the inside, odor components and harmful components contained therein are oxidized by the oxidation catalyst (19) in the decomposition section (19).
Deodorized or detoxified by a).

The processing gas circulating in the regeneration space (14) is discharged to the regeneration space (1) by operating the exhaust fan (23).
After being sucked little by little into the discharge passage (20) from 4), it is discharged outside the machine through the exhaust fan (23). At this time, the introduction passage is connected to the regeneration space (14) as the processing gas is discharged.
Air is sucked from (24). In the present embodiment, the reproduction space
The opening of the introduction valve (25) (that is, the amount of air introduced) is set so that the inside of (14) always has a slight negative pressure, and as a result,
The desorption of odor components and harmful components from the adsorption rotor (12) is promoted, and air leakage from the regeneration space (14) and odor leakage associated therewith are less likely to occur.

Further, in the auxiliary decomposition section (21) of the discharge passage (20), the catalyst (21a) is activated by being heated by the electric heater (22). Therefore, the processing gas sucked from the regeneration space (14) into the discharge passage (20) has an oxidation catalyst (21) in the auxiliary decomposition section (21) even if odor components and harmful components remain therein.
According to a), these components are decomposed and made odorless or harmless. Then, the odorless and harmless processed gas in which the odor component and the harmful component have been reliably processed in this way is discharged from the exhaust fan (23) to the outside.

The processing gas is supplied to an electric heater in the regeneration space (14).
It is hot because it is heated by (16) and the electric heater (22) of the auxiliary decomposition part (21), but the heat is given to the introduced air when passing through the double tube heat exchanger (26) . That is, the exhaust gas is cooled and discharged outside the device, while the introduced air is heated and then introduced into the regeneration space (14).

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) evaporates. When the temperature becomes low later, dew condensation occurs in the apparatus.In this embodiment, although the processing gas is circulated in the regeneration space (14), the processing gas is discharged from the discharge passage (20) to the outside. However, since the outside air is introduced, the rise in humidity in the regeneration space (14) can be suppressed, and condensation after cooling can be prevented.

-Effects of Embodiment- According to this 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.

Although the processing gas heated to a high temperature during the regeneration of the adsorption rotor (12) is circulated in the regeneration space (14), the processing gas is discharged from the regeneration space (14) little by little. Since air is introduced little by little into the regeneration space (14) to ventilate it, the heater in the regeneration space (14)
Even if the (16) and the fan (17) are stopped and the inside of the reproduction space (14) is cooled down to room temperature, it is possible to prevent condensation from occurring on the cover (15) of the reproduction space (14). Therefore, it is possible to prevent mold and rust from being generated in the apparatus due to dew condensation, and to prevent water droplets from leaking into the room.

Further, since the regeneration space (14) is always kept at a slightly negative pressure when the gas is discharged during regeneration, odor may leak from between the adsorption rotor (12) and the cover (15). Nor. Furthermore, since the regeneration space (14) has a slight negative pressure, desorption of odorous and harmful components from the adsorption rotor (12) is promoted. Decomposition performance is improved compared to the 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, the processing gas is deodorized or made harmless in the decomposition section (19) in the regeneration space (14), and then is further discharged.
Since the auxiliary decomposition section (21) in (0) is also decomposed and then exhausted, odor components and harmful components can be reliably removed.

Further, the oxidation catalyst (21a) of the auxiliary decomposition section (21)
Is provided around the playback space (14), so the playback space (14)
Since the catalyst (21a) can be preheated by utilizing the internal heat, the heat can be effectively used and the capacity of the auxiliary heater (22) can be suppressed.

After heating the introduced air, the regeneration space (1
Since the air is sucked into 4), even if the heating in the regeneration space (14) is suppressed, the odor component and the harmful component from the adsorption rotor (12) can be sufficiently removed. For this reason, it is possible to save energy such as reducing power consumption.

-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.

Further, in the above-described embodiment, the adsorption rotor (12) is regenerated while ventilating the inside of the regeneration space (14). At the time of regeneration, ventilation is performed only by circulating high-temperature gas in the regeneration space (14). The playback space after the end of the playback process without performing
(14) The inside air and the outside air may be exchanged.
Even in this case, since the water in the reproduction space (14) can be discharged, the occurrence of dew condensation in the apparatus can be prevented.
