Abstract

PROBLEM TO BE SOLVED: To provide a honeycomb body which can fully display the characteristics of a functional sheet by combining a corrugated netting with a planar functional sheet or a corrugated functional sheet with a planar netting. SOLUTION: A corrugated netting 2 and a planar adsorptive sheet 1 are bonded to each other to obtain a honeycomb body 3 by lamination. Further, an air to be treated containing an organic solvent vapor is blown to the honeycomb body 3 from a direction where the corrugations of the corrugated netting 2 are not visible. Consequently, the air passes through the mesh of the corrugated netting 2 to generate a turbulence due to the mesh. Thus the air to be treated certainly runs into a planar adsorptive sheet 1 and the organic solvent vapor contained in the air is adsorbed into the adsorptive sheet 1. Therefore, when the functional sheet is the adsorptive sheet 1 or the catalytic sheet, the air passing through the honeycomb body 3 comes into contact adequately with the adsorptive sheet 1 or the catalytic sheet to enable fully displaying of the adsorptive or catalytic function of the sheet.

However, among the above-mentioned conventional ones, the former one is a case where the sheet constituting the honeycomb body is activated by irradiating light such as ultraviolet rays like a photocatalyst, for example. However, there is a problem that light is difficult to pass through.

[0005] Alternatively, if the sheet has a sufficient capacity as a catalyst or an adsorbent, and both the corrugated sheet and the flat sheet need not be functional sheets such as a catalyst and an adsorbent, both the corrugated sheet and the flat sheet are used. There was a problem that there was no need to use a functional sheet.

[0006] Of the above-mentioned conventional ones, the latter one can be expected to have a sufficient effect as a device for capturing rough dust. However, it is difficult to form a honeycomb body using a functional sheet such as a catalyst or an adsorbent. There is no disclosure on how to fully utilize the features of the functional sheet.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a honeycomb body which makes full use of the features of a functional sheet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is a lamination of a corrugated net and a flat suction sheet, and a turbulence generated by the net causes a fluid to be treated on the suction sheet. It has the effect of hitting effectively.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 of the present invention will be described below. FIG. 1 is an exploded perspective view of Embodiment 1 of the present invention. Reference numeral 1 denotes a flat adsorption sheet, for example, an activated carbon sheet. Reference numeral 2 denotes a corrugated net, which is made of, for example, nylon. As a method of forming the corrugated net 2, a net made of a thermoplastic material such as nylon is passed between a pair of molded gears that have been heated.

The corrugated net 2 and the flat suction sheet 1 produced in this manner are adhered to each other and laminated.
The honeycomb body 3 as shown in FIG. At this time, the adhesive is applied only to the apex of the corrugated net 2 to minimize the area of the adhesive covering the planar suction sheet 1 as much as possible.

In the honeycomb body 3 obtained in the above description of the first embodiment, air to be treated containing, for example, organic solvent vapor flows in the direction of the arrow in FIG. 2, that is, in the direction in which the corrugated net 2 waves are not visible. Then, the air to be processed passes through the mesh of the corrugated net 2, and turbulence is generated by the mesh as shown in FIG.

Thus, the air to be treated surely hits the planar adsorption sheet 1, and the organic solvent vapor contained in the air to be treated is adsorbed on the planar adsorption sheet 1.

In the above embodiment, an example of an activated carbon sheet is shown as the planar adsorption sheet 1. Alternatively, paper into which zeolite, silica gel powder, or polymer synthetic adsorbent powder has been used can be used.

Hereinafter, a second embodiment of the present invention will be described.
The structure of the second embodiment is basically the same as that of the first embodiment, and the same portions are denoted by the same reference numerals.

The second embodiment is identical in appearance to the first embodiment shown in FIG. 1. Reference numeral 1 denotes a planar catalyst sheet, for example, a photocatalyst sheet. Reference numeral 2 denotes a corrugated net, which is made of, for example, nylon.

In the second embodiment, similarly to the first embodiment, when air flows in the direction of the arrow in FIG. 2, the air to be processed passes through the mesh of the corrugated net 2 and turbulence is generated by the mesh. I do. As a result, the air to be processed surely hits the planar catalyst sheet 1, and the organic solvent vapor contained in the air to be processed is decomposed in the planar catalyst sheet 1.

In the second embodiment, when light is applied to activate the catalyst sheet 1, the light passes between the corrugated nets 2 and passes over the entire surface of the catalyst sheet 1. You can guess.

The appearance of the third embodiment is the same as that of the first embodiment shown in FIG. 1. Reference numeral 1 denotes a flat suction sheet, which is the same as that of the first embodiment. Reference numeral 2 denotes a corrugated net, which is made of, for example, platinum or another metal wire plated with platinum and has a catalytic action.

In the third embodiment, similarly to the first embodiment, when air flows in the direction of the arrow in FIG. 2, the air to be processed passes through the mesh of the corrugated net 2 and turbulence is generated by the mesh. I do. Thereby, the air to be treated surely hits the planar adsorption sheet 1, and the organic solvent vapor contained in the air to be treated is adsorbed on the planar adsorption sheet 1.

In the case of the third embodiment, even when oil vapor which solidifies by oxidation such as tempura oil enters, it is decomposed by the catalytic action of the corrugated net 2 and adsorbed sheet. Even if it adheres to 1, it hardly hardens. Therefore, the solidified oil does not cover the surface of the adsorption sheet 1 and hinder the subsequent adsorption.

FIG. 4 is an exploded perspective view of the fourth embodiment. Reference numeral 4 denotes a corrugated suction sheet, and reference numeral 5 denotes a flat net. These are laminated to form a honeycomb body 6 shown in FIG.

When the processing air flows through the honeycomb body 6 configured as described above, the processing air can pass through the planar net 5, and as shown in FIG. 5, the winding air formed by the corrugated suction sheet 4 is formed. Passing through the passage 7. Therefore, the processing air passes through the long and winding path 7, and when the processing air contains the organic solvent vapor, the organic solvent vapor is reliably adsorbed on the adsorption sheet 4.

In the above-described embodiment 4, the example of the adsorption sheet 4 is shown, but this sheet may be a catalyst sheet, and the flat net 5 may be a catalyst.

FIG. 6 is a perspective view of the fifth embodiment, and FIG. 7 is a perspective view of the fifth embodiment. In the fifth embodiment, a honeycomb body 1 is formed by laminating a corrugated hydrophilic paper 8 and a flat net 9.
0 is configured.

Air is allowed to pass in the direction of the arrow in FIG. 7 while water is dropped on the upper end face of the honeycomb body 10 thus configured. Then, the water is sucked into the corrugated hydrophilic paper 8 and gradually falls downward. That is, the water falls while wetting the corrugated hydrophilic paper 8 which is meandering.

Since the corrugated hydrophilic paper 8 has a large area in contact with the airflow, the air passing through the honeycomb body 10 is given more moisture than the corrugated hydrophilic paper 8. As described above, the fifth embodiment effectively functions as a humidifying element.

[0028]

As described above, the honeycomb body of the present invention is constructed as described above, so that the features of the functional sheet can be sufficiently exhibited. That is, when the functional sheet is an adsorption sheet or a catalyst sheet, the processing air passing through the honeycomb body and the adsorption sheet or the catalyst sheet are sufficiently in contact with each other, and the function of the sheet adsorption or the function of the catalyst is sufficiently exhibited. In addition, since the passage of the processing air becomes longer and the contact area between the functional sheet and the processing air becomes larger, if the processing air flow path is meandering, the length of the processing air in contact with the functional sheet becomes longer, and the functional sheet becomes larger. Specific functions can be fully exhibited.
