  The present invention relates to an air cleaning apparatus that removes harmful gaseous chemical substances, and more particularly, to an air cleaning apparatus that improves the sustainability of the gaseous chemical substance removing effect and a trapping agent adjusting apparatus used therefor.

In recent years, health damage caused by indoor chemical substance contamination has been increasing, and the sick house problem has become a social issue.
This kind of sick house problem is caused by harmful gaseous chemicals such as formaldehyde and other VOCs (Volatile Organic Compounds). Something is already being provided to remove harmful gaseous chemicals.
Adsorption methods, catalyst methods, absorption methods and the like have already been proposed as methods for removing this kind of gaseous chemical substances.

As the adsorption method here, there is a method in which a gas removal filter containing activated carbon or a special ion exchanger is disposed in the air flow passage, and gaseous chemical substances are collected in the gas removal filter. (For example, refer to Patent Documents 1 and 2).
Further, as a catalytic method, there is a method in which a catalyst or an oxidant is attached or attached to a filter so that a gaseous chemical substance is rendered harmless by an oxidizing action of the catalyst or the oxidant (for example, Patent Document 3).
Further, as an absorption method, there is a method in which a gaseous chemical substance is absorbed and removed by water or a chemical solution permeated through a filter (see, for example, Patent Document 4).

And the valve opening 204 may be opened and closed by moving the shutter 202 forward and backward. Further, as shown in FIG. 18C, an opening / closing structure including a diaphragm mechanism 218 may be used as the shutter mechanism 217.

◎ Eighth embodiment
FIG. 19 shows the essential parts of Embodiment 8 of the air purifying apparatus to which the present invention is applied.
In this figure, the basic configuration of the air cleaning device is substantially the same as that of the seventh embodiment, but the capture agent supply device 101 for supplying the granular capture agent (granule) 50 of the capture agent adjusting device 100 is implemented. The configuration is different from that of the seventh embodiment. Components similar to those in the seventh embodiment are denoted by the same reference numerals as those in the seventh embodiment, and detailed description thereof is omitted here.

As described above, since the capture agent 50 is periodically exchanged in the storage space 52 of the gas removal filter 33, the gas removal performance of the gas removal filter 33 is equal to the total capacity of the capture agent 50 in the capture agent supply tank 180. The corresponding amount is always kept good.

Ninth embodiment
FIG. 20 (a) shows a main part of an air purifying apparatus according to Embodiment 9 to which the present invention is applied.
In the figure, the basic structure of the air purifier is the same as in the seventh and eighth embodiments, in which a trapping agent adjusting device 100 is added to the gas removal filter 33 and a granular trapping agent (granule) 50 is used. However, the configuration of the capture agent adjusting device 100 is different from those of the seventh and eighth embodiments.
The trapping agent adjusting device 100 used in the present embodiment is provided with a trapping agent supply device 101 below the storage space 52 of the gas removal filter 33 and a discharge device 112 above the storage space 52. It is.
In this example, the capture agent supply device 101 has a capture agent supply tank 220 connected in communication with the lower part of the storage space 52, and the bottom wall of the capture agent supply tank 220 is configured as an elevating plate 221 that can move up and down. The lift plate 221 is supported by a lifter 222 so as to be movable up and down, and the lifter 222 is moved up and down by a drive motor 223.
On the other hand, the discharge device 112 has a waste tank 225 that is connected to the upper portion of the storage space 52.

In the present embodiment, the capture agent supply tank 220 stores in advance the capture agent 50 corresponding to the assumed life (for example, one year) of the gas removal filter 33. The lifter 222 is raised by a predetermined amount via the drive motor 223 at regular intervals according to the replacement period.
Then, the trapping agent 50 in the trapping agent supply tank 220 is pushed upward by the lifting plate 221 and pushed up into the storage space 52 of the gas removal filter 33 to be filled. At this time, the old capture agent 50 stored in the storage space 52 of the gas removal filter 33 is pushed upward along with the push-up operation of the new capture agent 50 and is pushed up and discarded to the disposal tank 225 side. For this reason, the new trapping agent 50 is exchanged and stored in the storage space 52 of the gas removal filter 33, and the gas removal performance of the gas removal filter 33 is kept good.

Further, in the present embodiment, the capture agent supply tank 220 is configured by a single tank container, but is not limited to this. For example, as shown in FIG. Are configured as a plurality of divided tank packs 226 (for example, 226a to 226d) that can be sequentially shifted, and the upper and lower ends of the divided tank packs 226 are closed with a crushable hermetic seal (not shown), while the gas removal filter 33 An opening / closing shutter 227 is provided in the lower opening of the storage space 52, and a lifter 228 for lifting the trapping agent in the divided tank pack 226 is provided below the replenishing port of the gas removal filter 33 corresponding to the opening / closing shutter 227. It may be provided so as to be movable up and down.

The shifter 226 is shifted and the lifter 228 is raised to push and fill the trapping agent 50 in the divided tank pack 226 into the storage space 52 of the gas removal filter 33. The old capture agent 50 in the storage space 52 is pushed and discarded to the disposal tank 225 side with the filling operation of the new capture agent 50.
The divided tank back 226 has a structure in which the built-in trapping agent 50 is extruded and filled, but is not limited thereto, and is stored in the storage space 52 of the gas removal filter 33 for each divided tank pack 226. Each divided tank pack 226 may be discarded.

[Embodiment 10]
FIG. 21 shows an essential part of Embodiment 10 of an air cleaning apparatus to which the present invention is applied.
In the figure, the basic structure of the air purifier is that a particle removal filter 32, a gas removal filter 33 and an auxiliary filter 34 are arranged in order from the upstream side of the air flow passage 21, and the trapping agent adjusting device 100 is arranged in the gas removal filter 33. It is added.
In the present embodiment, the gas removal filter 33 has a movable web-like filter substrate 230. This filter substrate 230 is obtained by laminating a capture agent layer 232 containing a capture agent on a base substrate 231, and having a release agent layer 233 formed on the capture agent layer 232.

Further, the capture agent adjusting device 100 is one in which one end side of the web-like gas removal filter 33 is wound around the rewinding roll 240 so as to be freely rewound, and the other end side is engaged with the winding roll 241 so as to be rewound. In addition, the web-like gas removal filter 33 is sequentially moved in conjunction with the winding operation of the winding roll 241.
Here, the control device 200 drives the drive motor 242 at every predetermined movement timing and rotates the winding roll 241 by a predetermined amount to wind up and move the web-like gas removal filter 33. In this example, in this case, the web-like removal filter 33 is arranged substantially orthogonally with respect to the air flow passage 21, but the amount of rotation of the take-up roll 241 is substantially equal to that of the air-flow passage 21. It is set so as to move by the area.

  Furthermore, in the present embodiment, the capture agent adjusting device 100 includes an unused capture agent storage device 250 that can store the unused capture agent of the web-like gas removal filter 33 without deterioration. As shown in FIGS. 21 and 22 (a), the unused capture agent storage unit 250 has a rewinding holder 251 in which a rewinding roll 240 is accommodated. An outlet 252 is formed through which the filter 33 can be rewound, and a space between the outlet 252 and the web-like gas removal filter 33 is sealed with an elastic sealing material (seal member) 253. . However, the elastic sealing material 253 elastically contacts the web-like removal filter 33, but the degree of the elastic contact requires that the web-like removal filter 33 is slidable between the elastic sealing material 253.

In particular, in this embodiment, the rewinding holder 251 is integrally formed of a resin material, and one holder wall 251a sandwiching the outlet 252 is elastically deformable and closes the outlet 252. It is intended to be urged in the direction F. The elastic sealing material 253 may be any material that elastically fills at least the gap between the edge of the outlet 252 and the web-like gas removal filter 33.
On the other hand, a used capture agent storage device 260 is provided on the winding roll 241 side. As shown in FIG. 21, the used capture agent storage device 260 has a take-up holder 261 in which a take-up roll 241 is accommodated, and the web-like gas removal filter 33 can be taken up by the take-up holder 261. A recovery port 262 that is wound around is formed. Note that it is not necessary to provide a seal member between the recovery port 262 and the web-like gas removal filter 33, and a gap remains.

Next, the operation of the air cleaning apparatus according to the present embodiment will be described.
The contaminated air (cleaning target air) Air in the air flow passage 21 passes through the particle removal filter 32, the gas removal filter 33, and the auxiliary filter 34 in this order, as shown in FIG. During this time, the particle component is removed by the particle removal filter 32, the gaseous chemical substance is removed by the gas removal filter 33, and the product in the gas removal filter 33 is further removed by the auxiliary filter 34.
When the gaseous chemical substance continues to be captured by the trapping agent 50 held by the gas removal filter 33, the gas removal performance of the gas removal filter 33 gradually begins to deteriorate. For this reason, in the present embodiment, the control device 200 sends a predetermined replacement control signal in accordance with a predetermined replacement timing, moves the web-like gas removal filter 33 by a predetermined amount, and within the ventilation area of the air flow passage 21. The capture agent 50 is replaced with a new capture agent. Thereby, the gas removal performance by the gas removal filter 33 is kept favorable.

Further, in this embodiment, the unused capture agent storage device 250 seals the web-like gas removal filter 33 located in the rewinding holder 251 with the elastic sealing material 253 so as to avoid contact with contaminated air. Therefore, a situation in which the gaseous chemical substance in the contaminated air is adsorbed when the gas removal filter 33 in the rewinding holder 251 is not used is effectively avoided.
In particular, from the viewpoint of keeping the storage performance of the unused capturing agent better, it is preferable that the elastic sealing material 253 contains a capturing agent equivalent to the capturing agent 50. In this case, even if part of the contaminated air tries to enter the inside from between the outlet 252 of the rewinding holder 251 and the elastic sealing material 253, the gaseous chemical substance contained in the contaminated air at the elastic sealing material 253 portion. Since it is adsorbed and held, a situation in which the unused capture agent in the rewinding holder 251 is unnecessarily deteriorated due to an adsorption reaction or the like before use is effectively avoided.
In the present embodiment, the particle removal filter 32 is provided on the upstream side of the web-like gas removal filter 33, but the web-like gas removal filter 33 moves and exchanges the trapping agent 50. The web-like gas removal filter 33 may be used also as the particle removal filter without using the removal filter 33. In this case, it is preferable that the web-like gas removal filter 33 has a mesh configuration capable of removing particles and a configuration having physical adsorption properties and electroadsorption properties for particle removal.

Further, the unused capture agent storage device 250 is not limited to the embodiment shown in FIG. 22A, and may be appropriately selected as shown in FIGS. 22B to 22D.
For example, as shown in FIG. 22 (b), an outlet 252 is opened in a part of the rewind holder 251, and an elastic pressing plate 255 made of a leaf spring is cantilevered by a stopper 256 outside the rewind holder 251. A mode in which the web-like gas removal filter 33 drawn out from the outlet 252 is elastically held at the edge of the outlet 252 on the free end side of the elastic pressing plate 255 biased in the direction indicated by F Is mentioned.
In this aspect, since the web-like gas removal filter 33 is sandwiched between the edges of the outlet 252 by the elastic pressing plate 255, this sandwiching portion substantially exhibits a sealing function, and the web-like gas removal filter 33. It is avoided that the unused capture agent 50 is unnecessarily deteriorated by an adsorption reaction or the like before use.
In place of the elastic pressing plate 255, as shown in FIG. 22C, the cover plate 257 for opening and closing the outlet 252 of the rewinding holder 251 is urged by the urging spring 258, and this urged force is applied. The web-like gas removal filter 33 drawn from the outlet 252 by the lid plate 257 may be sandwiched between the edges of the outlet 252.

Furthermore, as another aspect of the unused capture agent storage device 250, as shown in FIG. 22 (d), an appropriate number of auxiliary capture agents 259 equivalent to the capture agent 50 are installed in the rewinding holder 251 as appropriate. An embodiment is mentioned.
According to this aspect, even if contaminated air enters the rewind holder 251 from the outlet 252 of the rewind holder 251, the gaseous chemical substance contained in this contaminated air acts by the auxiliary capture agent 259 such as adsorption. Captured effectively at For this reason, the unused capture agent 50 of the web-like gas removal filter 33 is not unnecessarily deteriorated by an adsorption reaction or the like before use.
In this embodiment, the outlet structure 252 of the rewinding holder 251 is not provided with a sealing structure (such as using an elastic sealing material or a holding structure at the edge of the outlet). A seal structure as shown in (c) may be used together.

Moreover, in this Embodiment, although the web-like gas removal filter 33 is comprised by the single row | line | column as shown to Fig.23 (a), it is not restricted to this, For example, FIG.23 (b) As shown, an appropriate number (for example, three) of stretching rolls 243 is used in addition to the rewinding roll 240 and the winding roll 241, and the web-like gas removal filter 33 is folded and arranged in a plurality of stages via the folding part 244. Alternatively, as shown in FIG. 23C, a plurality of rows (a plurality of stages) of web-like gas removal filters 33 (for example, 33a and 33b) may be used.
Here, as shown in FIGS. 23B and 23C, in the embodiment using a plurality of stages of the web-like gas removal filter 33, a plurality of kinds of gaseous substances are obtained by separately holding a plurality of kinds of capture agents. It is possible to remove chemical substances effectively.
Furthermore, as shown in FIG. 21, the layout of the web-like gas removal filter 33 shows a mode in which the web-like gas removal filter 33 is arranged substantially orthogonal to the air traveling direction of the air flow passage 21, but is not limited thereto. For example, as shown in FIG. 24 (a), the web-like gas removal filter 33 may be disposed substantially closed with respect to the air traveling direction of the air flow passage 21, or as shown in FIG. 24 (b). As described above, for example, a plurality of rows of web-like gas removal filters 33 (for example, 33a and 33b) are used. However, the winding roll 241 may also be used from the viewpoint of reducing the number of parts.
