Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a regenerator for an air purifying adsorbent for adsorbing and removing odorous or harmful gas components in air, an air purifying apparatus provided with a regenerating section for the adsorbent, and an air purifying system. About.

[0002]

2. Description of the Related Art In order to remove odor components or harmful gas components in air, an adsorbent that adsorbs the odor components or harmful gas components and an odor component or harmful gas components that desorb from the adsorbent are decomposed. It is generally known to incorporate a catalyst structure comprising a catalyst, an adsorbent and a heater for heating the catalyst into an air purifier, a refrigerator, an air conditioner, or the like. In this case, the adsorbent is regenerated by removing the odor component or the harmful gas component by heating with the heater.

For example, JP-A-5-146683 discloses a catalyst layer formed on a surface of a substrate by using zeolite and active alumina serving as an adsorbent as carriers and supporting a platinum group metal serving as a catalyst on the carrier. An air purification catalyst structure in which a heater is arranged on the back side of a substrate is described. In this method, odor components in the room are adsorbed by zeolite and activated alumina, and when the adsorption capacity is near the limit, the odor components are oxidized and decomposed by heating the catalyst layer to regenerate the odor components. .

[0004]

However, in the conventional air purifying catalyst structure, the adsorbent having the adsorbent is heated by the heater while being kept at the place where the odor component is adsorbed. It is not suitable for use in spaces where the temperature is controlled, such as indoors. That is, since the adsorbent is heated during cooling, the heating efficiency is poor, and the heat of the heater is radiated into the room to be cooled, so that the indoor temperature rises. Loss was large and uneconomical. on the other hand,
If the area of the adsorbing section of the adsorbent is reduced to reduce the above energy loss, it becomes impossible to secure the necessary deodorizing ability.

On the other hand, it is conceivable to replace the adsorbent without regenerating the adsorbent, but if there are many places where odor components or harmful gas components must be removed, the replacement cost increases. There are also air purifiers using the ozone method, air purifiers that use a large amount of adsorbent, and air purifiers that combine photocatalysts and adsorbents to promote adsorption and decomposition at the same time. high.

[0006]

In order to solve such a problem, the present inventor has proposed an adsorbent (1) having an adsorbent and an adsorber for adsorbing an odor component or a harmful gas component in the air. By separating the regenerating unit for regenerating the adsorbent (1),
The inventors have found that the above-mentioned heating efficiency can be improved and energy loss can be reduced, and the present invention has been completed.

That is, the invention of this application is a regenerator for an air cleaning adsorbent having an adsorbent for adsorbing odorous or harmful gas components in the air, wherein the adsorbent (1) comprises:
A plurality of adsorbent units (2), which are connected so as to form one wide adsorption surface and are used for adsorbing the odor component or the harmful gas component in the air; A housing part (4) for housing the units (2) side by side, and a heater () for heating the adsorbent unit (2) housed in the housing part (4) such that the odor component or the harmful gas component is desorbed. 6) and a catalyst (7) for decomposing odorous or harmful gas components desorbed from the adsorbent unit (2).

The odor components include, for example, ammonia, acetaldehyde, trimethylamine, methyl mercaptan, hydrogen sulfide and the like.
CO, NOx (nitrogen oxide), SOx (sulfur oxide) and the like. In this specification, the term “odor component or harmful gas component” refers to only one of the two types, the case of multiple types of one of the two types, Including the case of targeting both gaseous substances. That is, “or” here means that at least one of them is targeted.

In the case of the present invention, since the adsorbent (1) is regenerated by a regeneration-only device, for example, room air is not heated for the regeneration, and the heating efficiency at the time of regeneration is also increased. . In particular, since the adsorbent (1) is divided into a plurality of adsorbent units (2), and these are arranged side by side vertically or horizontally and accommodated in the accommodating portion (4), and are collectively reproduced.
The size of the regenerator itself does not increase, and the heating efficiency and the efficiency of decomposing odorous or harmful gas components by the catalyst (7) also increase. In this case, the heater (6) not only functions to heat the adsorbent unit (2), but also functions to heat the catalyst (7) to promote its activity.

Further, each of the adsorbent units (2) is formed in a plate shape, and a plurality of plate-shaped adsorbent units (2) are arranged such that the plate surfaces of adjacent adsorbent units (2) face each other. The heater (6) and the catalyst (7) are provided on both sides of the plurality of adsorber units (2) arranged side by side so as to sandwich the plurality of adsorber units (2) arranged side by side. For example, a plurality of adsorbent units (2) can be efficiently regenerated without providing a heater (6) and a catalyst (7) for each adsorbent unit (2), and
This is also advantageous in reducing the size of the regenerator.

As the above-mentioned adsorbent, for example, zeolite, silica gel, activated alumina, granular activated carbon, activated carbon fiber, or the like can be used. The adsorbent unit (2) can be formed by being supported on a light or other porous plate-like substrate, or the adsorbent unit (2) can be obtained by compression-molding a fibrous adsorbent into a plate shape. it can.

Regarding the catalyst (7), Ag, Cu,
Pd, Pt, Mn, Ni, Co, Fe and the like can be adopted, and one selected from these or a combination of two or more thereof may be used by being supported on a wire or a porous carrier. . Further, such a metal catalyst component, for example,

Can be used by being supported on the above-mentioned linear body or porous carrier.

Another invention of this application is an air purifying apparatus provided with an adsorbent (1) having an adsorbent for adsorbing odor components or harmful gas components in the air, wherein the adsorbent (1) comprises: A plurality of adsorbent units (2), the plurality of adsorbent units (2) are arranged in series so as to form one wide adsorption surface, and the odor component or An adsorbing section (11) for adsorbing the odorous or harmful gas component by contacting the air containing the harmful gas component, and the adsorbent units (2) provided beside the adsorbing section (11) are arranged side by side. An accommodating section (4) for accommodating the adsorbent, a heater (6) for heating the adsorbent unit (2) accommodated in the accommodating section (4) such that an odor component or a harmful gas component is desorbed, and the adsorbent unit Odor component or harmful gas desorbed from (2) Characterized in that it includes a reproduction unit (12) having a catalyst (7) degrades minute.

According to the present invention, a plurality of adsorbent units (2) are connected to each other and arranged on the adsorbing portion (11) so as to extend over the entire surface thereof, thereby increasing the adsorbing area and increasing the odor component or harmful gas component in the air. When the adsorbent (1) is regenerated, it is divided into a plurality of adsorbent units (2) and stored in the storage section (4) of the regenerating section (12).
Heating can be performed efficiently at one place, and room air is not heated in the adsorption section (11).

[0015] Still another invention of this application has an attachment portion to which an adsorbent (1) having an adsorbent for adsorbing odor components or harmful gas components in the air is attached and detached, and is attached to the attachment portion. An air purifier (2) for bringing the adsorbent (1) into contact with air to adsorb odorous or harmful gas components in the air.

And an air purification system comprising a combination with a regenerator (3) that decomposes an odor component or a harmful gas component desorbed from the adsorbent (1) with a catalyst.

In the case of the present invention, since the regenerator (3) can be placed in a different place from the room where the air purifier (21) is installed, the air purifier (3) is used for regenerating the adsorbent (1). 2
There is no need to heat the room where 1) is installed. Further, since the air purifier (21) does not need to be heated, it can be used even in a place where power cannot be taken. Further, since the adsorbent (1) is regenerated and used, there is no disadvantage in cost.

The adsorbent (1) may carry a catalyst together with the adsorbent. When the adsorbent (1) does not carry a catalyst, a catalyst is provided in the regenerator (3). However, when the adsorbent (1) carries a catalyst, it is not necessary to separately provide a catalyst.

The combination of the air purifier (21) and the regenerator (3) may be a combination of one air purifier (21) and one regenerator (3).

This is because it can be decomposed and removed.

In the above-described air cleaning system, it is preferable that the air cleaner (21) is further provided with a nonwoven fabric filter or an electric dust collector. As a result, for example, smoke, smell, or dust of cigarettes in a room can be removed.
