[0002]

2. Description of the Related Art Conventionally, polytetrafluoroethylene (hereinafter, referred to as PTFE) obtained by emulsion polymerization of tetrafluoroethylene (hereinafter, referred to as TFE) has been disclosed in Japanese Patent Application Laid-Open No. 4-154842. It has been known that it has a unique property of fibrillating when subjected to a shearing force, and this property is used as a binder for powder. That is, when the above-mentioned PTFE is mixed with the powder and stirred, the PTFE is fibrillated, and the powder is carried by the fibrillated PTFE to form a nodule, which is further rolled to form a sheet-like material.

SUMMARY OF THE INVENTION However, PTF
E has conventionally been used to form powder into a sheet, but there has been a problem that it has not been utilized to form a catalyst structure comprising a catalyst and an adsorbent into a sheet. That is, there is a problem that PTFE is not sufficiently utilized as a binder for a powdery catalyst or an adsorbent.

Further, in the conventional catalyst structure, since a catalyst coating layer is formed on the surface of a base material such as a metal, it is difficult to form the catalyst structure into a complicated shape. There was a problem that sufficient air cleaning ability could not be exhibited. That is, in order for the catalyst structure to exhibit sufficient air cleaning ability, it is desirable to increase the surface area of the catalyst structure and increase the contact area between the catalyst structure and air as much as possible. On the other hand, since the catalyst structure is installed in a limited space inside an air conditioner or the like, it needs to be small. Therefore, in order to achieve both the enlargement of the surface area and the miniaturization of the catalyst structure, it is necessary to form the catalyst structure in a complicated shape such as a honeycomb shape or a folded shape. On the other hand, the conventional catalyst structure is difficult to form into a complicated shape as described above, and the surface area cannot be increased, and as a result, sufficient air cleaning ability cannot be exhibited. was there.

[0006] In addition, the adsorbent, when adsorbing a predetermined amount of odorous substances or harmful substances, has a reduced adsorbing ability. Therefore, it is necessary to regenerate the adsorbent by heating it. However, the conventional catalyst structure has no flexibility because it has the substrate as described above,
There was a problem that the adsorbent could not be efficiently regenerated. In other words, since the catalyst structure is not flexible,
The catalyst structure had to be heated in the same state as when adsorbing odorous substances or harmful substances. For this reason,
For example, when the catalyst structure is regenerated while the room is being cooled, heat is radiated from the catalyst structure so much that the catalyst structure cannot be quickly heated, and much energy is required for heating. As a result, there has been a problem that the adsorbent cannot be efficiently regenerated.

[0007] Attempts to form a flexible catalyst structure have been made in the past. Specifically, it has been attempted to form a powdery catalyst or adsorbent into a sheet using a general organic polymer as a binder. However, in this catalyst structure, it is difficult to form a sheet having a small thickness and the flexibility is insufficient, or the organic polymer covers the surface of the catalyst or the adsorbent and has a sufficient air cleaning ability. There was a problem that it could not be demonstrated.

[0008] The present invention has been made in view of the above points, and it is an object of the present invention to provide a flexible sheet material containing a catalyst or an adsorbent, and a catalyst structure using the sheet material. It is to realize.

It is arranged to adsorb and remove odorous substances or harmful substances in it.

-Manufacturing method of deodorizing sheet-Here, the manufacturing method of the deodorizing sheets (21a to 21e) will be described. First, PTFE is obtained by emulsion polymerization of tetrafluoroethylene (TFE). In particular,
A pressure-resistant autoclave is charged with water containing 100 to 20,000 ppm of a surfactant, and after degassing, the initiator and TFE are charged and reacted while stirring at 0 to 120 ° C. and 1 to 50 atm. Fine PTFE having a particle size of 1 μm is obtained. At the time of emulsion polymerization, TFE is continuously supplied while being pressurized in a gaseous state. And the obtained PTFE
Is coagulated and dried to obtain the fine particle PTFE aggregated powder.

Thereafter, the above-mentioned sheet material (1) is mixed with a powdery catalyst and adsorbent, and 1 to 20 with respect to the catalyst and adsorbent.
A sheet-like material (1) is formed by rolling a mixture obtained by mixing and stirring the PTFE with a weight percentage of PTFE into a sheet. Specifically, a powdery catalyst and an adsorbent are dispersed in water, a predetermined amount of the PTFE aqueous dispersion is added thereto, and the mixture is stirred. As a result, the catalyst and the adsorbent and the PTFE are uniformly mixed, and then the water is evaporated to obtain a mixture of the catalyst, the adsorbent and the PTFE. Then, when the shear force is applied to the PTFE by stirring the mixture or the like, the PTFE is fibrillated, and the fibrillated PTFE is entangled with the catalyst and the adsorbent to form an agglomerate, which is further rolled to form a sheet layer (2). Thus, a sheet material (1) is obtained. The sheet material (1) is cut into a predetermined shape to form deodorizing sheets (21a to 21e).

On the other hand, the above catalyst is composed of Al ₂ O ₃ , ZrO ₂ , CeO ₂ , S
One or more metal oxides selected from iO ₂ and zeolite or a mixture of the metal oxide and a metal composite oxide is used as a carrier, and the carrier contains Ag, Pd, P
one or more metals selected from t, Mn and Rh,
An alloy containing the metal, an oxide of the metal, or a mixture of two or more thereof is supported. Then, it is activated by being heated to about 200 ° C or higher, and decomposes odorous substances or harmful substances to make them odorless or harmless. The adsorbent is made of zeolite and adsorbs odorous substances or harmful substances.

-Operation- The operation of the air purifier (10) will be described. When the fan (16) rotates, the room air flows into the suction port (12).
Flows into the air passage (14). The air flowing into the air passage (14) flows through the pre-filter (15), and the pre-filter (15) removes suspended substances such as dust. Thereafter, the room air flows to the adsorption section (26) of the air purification section (20),
The deodorizing sheet (21a) arranged in the unfolded state on the adsorption section (26)
When flowing in the width direction of the deodorizing sheet (21a to 21e) while being in contact with the deodorizing sheet (21a to 21e), odorous substances or harmful substances contained in the room air are adsorbed and removed by the adsorbent of the deodorizing sheet (21a to 21e). , And becomes purified air. Then, the purified air flows through the air passage (14) and blows out from the outlet (13) again into the room.

The air purifying section (20) includes an air purifier (10)
During the operation of, the following purification operation is performed. First, in the adsorbing section (26), the deodorizing sheets (21a to 21e) are in an expanded state, and the adsorbent of the deodorizing sheets (21a to 21e) is in the air passage (1).
4) Adsorb odorous substances or harmful substances contained in the indoor air flowing through. Thereafter, when the adsorbent adsorbs odorous substances or harmful substances for a predetermined period of time and the adsorption capacity of the adsorbent decreases, the right and left take-up rolls (22R, 22L) rotate forward to rotate the deodorizing sheets (21a to 21a). 21e) crosses the suction section (26) from left to right. Then, the portion of the deodorizing sheet (21a to 21e) containing the adsorbent having reduced adsorption capacity is the right take-up roll (2).
2R), while the portion of the deodorizing sheet (21a to 21e) that has been wound on the left wind-up roll (22L) is deployed on the suction section (26). That is, the deodorizing sheet (21a to 21e) provided with an adsorbent that has not yet adsorbed odorous substances or harmful substances is deployed in the adsorbing section (26), and the air passage (14) of the air purifier (10) is opened. ) Comes into contact with the room air flowing through, and odorous substances or harmful substances contained in the room air are reliably removed. This operation is repeated until the deodorizing sheets (21a to 21e) are wound around the right winding roll (22R) to continuously purify the air.

Next, when the deodorizing sheets (21a to 21e) are wound up on the right winding roll (22R), a regenerating operation is performed. At this time, the deodorizing sheet wound on the right take-up roll (22R)
The adsorbents (21a to 21e) adsorb odorous substances or harmful substances, but when the deodorizing sheets (21a to 21e) are heated by the electric heater of the regeneration section (27), they are adsorbed by the adsorbents. The odorous substances or harmful substances that have been desorbed desorb and the adsorbent is regenerated. On the other hand, since the catalyst of the deodorizing sheets (21a to 21e) is also heated and activated, the odorous substance or harmful substance released from the adsorbent is decomposed by the catalyst and made odorless or harmless. Then, the deodorized sheets (21a to 21e) in which the adsorbent has been regenerated are attached to the right and left take-up rolls (22R,
22L) to move from the right take-up roll (22R) to the left take-up roll (22L).
2L), and then the above purification operation is performed.

The deodorizing sheets (21a to 21e) contain a powdery adsorbent and a catalyst, and both are formed into a sheet in a state of being uniformly mixed. Therefore, at the time of the regenerating operation of the air purifying section (20), the odorous substance or the harmful substance desorbed from the adsorbent is decomposed by the catalyst present immediately near the adsorbent immediately after desorbing, thereby deodorizing. Alternatively, it can be made harmless, and as a result, it is possible to reliably prevent the odorous substance or the harmful substance desorbed from the adsorbent from flowing out of the regeneration section (27) and contaminating the indoor air.

Further, a long deodorizing sheet (21a-21)
e) is wound up on the left take-up roll (22L) and can be sequentially sent out to the suction section (26), so that air can be continuously deodorized for a long time.

In the suction section (26), the room air flows between the five deodorized sheets (21a to 21e) in the unfolded state in the width direction of the deodorant sheets (21a to 21e). The contact area between the air and the deodorizing sheets (21a to 21e) can be made large, and as a result, odorous substances or harmful substances contained in the indoor air can be reliably absorbed and removed, and the indoor air can be reliably purified. It can be carried out.

The adsorbents a to 21e) can be regenerated. Therefore, the regeneration of the adsorbent can be performed only by maintaining the inside of the regeneration section (27) at a high temperature, and the energy required for regeneration of the adsorbent can be reduced. Further, since the wall surface of the regeneration section (27) is formed as a heat insulating wall, the amount of heat radiation from the inside of the regeneration section (27) to the outside can be reduced during the above-mentioned regeneration operation. Energy required for regeneration can be reduced. Also, deodorizing sheets (21a-21)
Since e) is maintained at a high temperature, it is possible to sterilize germs trapped on the deodorizing sheets (21a to 21e).

According to this, the adsorbent of the deodorizing sheets (21a to 21e) can be regenerated even when the deodorizing sheets (21a to 21e) are wound on the left take-up roll (22L).
In other words, in the first embodiment, the right and left winding rolls (22R, 22L) are rotated after the adsorbent of the deodorizing sheets (21a to 21e) is regenerated by the regenerating operation. The step of winding the deodorized sheet (21a to 21e) wound on the left side into the left take-up roll (22L) becomes unnecessary, and immediately after the regenerating operation, the right side of the deodorized sheet (21a to 21e) is wound. The purifying operation can be performed while winding from the roll (22R) to the left take-up roll (22L), and the time required from the end of the purifying operation to the start of the next purifying operation can be reduced.
