The activated carbon fiber bag-like body 19 of the second filter body 9 has an activated carbon fiber layer 19a formed by laminating fibrous activated carbon as shown in the sectional view of FIG. 6, and the front and back of the activated carbon fiber layer 19a. , Respectively. The permeable sheet materials 19b and 19c also have a function as shape-retaining members for maintaining the shape of the activated carbon fiber layer 19a.

Next, the above-mentioned odor removing device 6 for painting operation is used.
The renovation work at the entrance and exit of the elevator, which is performed by using the above, will be described. Now, if you are hanging or painting a building wall to renovate an elevator entrance,
As shown in FIG. 1, a frame 3 is assembled in front of a three-way frame 5 at the entrance of the elevator, and the outside of the frame 3 is covered with a vinyl sheet 4 and then the main body is inserted into an opening 4a formed in a part of the vinyl sheet 4. The case 7 is connected. The electric blower 10 is connected to the exhaust side of the main body case 7 via the connecting cylinder 22,
The exhaust cylinder 23 is connected to the exhaust side of the electric blower 10 to assemble the odor removing device 6 for painting work.

Thereafter, when the electric blower 10 is rotated,
Air containing dust, paint powder, and odor generated during the hanging operation and the painting operation in the temporary enclosure device 2 is sucked into the main body case 7. Dust and coating powder in the air sucked into the main body case 7 are removed by the first filter body 8, and the odor passing through the first filter body 8 is removed by the second filter body 9. At this time, the first filter body 8
Since the back side of the polyester filter 15 is supported by the wire mesh 16, it does not expand and deform due to the flow of air. In addition, since the back side of the activated carbon fiber bag 19 is also supported by the wire mesh 20, it does not expand and deform due to the flow of air, so that the activated carbon fiber bag 19 does not need to have rigidity. In addition, the entire activated carbon fiber bag-like body 19 can have a flexible structure, and the polyester filter 15 can be made thin. In this way, clean air without odor is discharged from the outlet 7b of the main body case 7, and is discharged to the outside via the exhaust cylinder 23.

The odor removing device 6 for coating work removes dust and paint powder by the first filter body 8 and removes the odor by the second filter body 9 disposed downstream thereof. Dust and coating powder hardly adhere to the filter body 9, and a sharp decrease in the odor removing ability of the second filter body 9 can be prevented. Further, since a plurality of the second filter bodies 9 are housed in the main body case 7 so as to be arranged side by side, the odor is almost eliminated by selecting the number under the use condition, and the second filter body 9 Since the activated carbon fiber layer 19a capable of regenerating the odor removing ability is used, the expensive second filter body 9 can be reused many times.

During this operation, if the polyester filter 15 in the first filter body 8 is clogged due to adhesion of paint powder or the like, the screw 17a shown in FIG. Only the polyester filter 15 needs to be replaced with a new one, and the frame plate 14 and the mounting plate 17 can be reused. However, if the polyester filter 15 is clogged, the frame plate 1
The entirety of the first filter body 8 in which the polyester filter 15 is incorporated in the unit 4 can be replaced as a unit.
In any case, the polyester filter 15 of the first filter body 8 is attached to the entire surface of the main body case 7 although it may be necessary to replace the filter 15 with a new one in a relatively short time due to a large amount of coating powder. Therefore, since there is no need to disassemble the main body case 7 each time the replacement is performed, the replacement operation is easy.

On the other hand, when the odor removing ability of the activated carbon fiber bag-like body 19 of the second filter body 9 is reduced, the screw 21a shown in FIG. Only the fiber bag-like body 19 may be set in a reproducing device (not shown) for reproduction. On the other hand, the regeneration of the activated carbon fiber bag-like body 19 by this regeneration device is performed at another time, and the unit of the second filter body 9 can be replaced. When the activated carbon fiber bag 19 is damaged and becomes unusable, only the activated carbon fiber bag 19 is replaced with a new one, and the frame plate 18 and the mounting plate 21 are reused. Or the entire second filter body 9 can be replaced with a new one.

In the above-described embodiment, the first filter body 8 is formed by providing the wire mesh 16 only on the back surface side of the polyester filter 15.
5, a wire mesh may be provided on both the front and back surfaces, and the polyester filter 15 may be sandwiched between the wire meshes. In addition, if a silencer is provided in the exhaust cylinder 23, the electric blower 1
