On the other hand, a small amount of heating fluid flows into a separate desorption area from the adsorption area into which the fluid to be treated flows, and the material to be treated contained in the fluid to be treated with a large amount of air is transferred to the heating fluid with a small amount of air. In this way, a so-called concentrated fluid containing a high-concentration material to be treated is generated with a small air volume, and this concentrated fluid is separately subjected to secondary treatment by a treatment apparatus provided outside, thereby reducing the total treatment cost. can be done.

[Adsorption unit 30]
A specific structure of the adsorption unit 30 in the embodiment will be described with reference to FIG. FIG. 6 is an overall perspective view of the suction unit 30 in this embodiment.

The adsorption unit 30 has a plate-like adsorption element 200 having a honeycomb structure as described above, and a plurality of adsorption elements 200 which are stacked so as to communicate with an inflow side opening and a discharge side opening and form a flow path for the fluid to be treated. and a frame body 30F1 that is stacked and held. A layered body 200A is formed by stacking the adsorption elements 200 in a layered state.

When configuring the laminate 200A, the frame 30F1 alone may be fixed, or the adsorption elements 200 may be fixed together using an adhesive. An inorganic binder can be used as the adhesive.

The inorganic binder is, for example, soluble in water, the binder is uniformly dispersed in the sheet, and hardens by reaction, gelation, etc. during heat treatment, and firmly fixes the adsorbent and the framework material during the hardening. is. In addition, the thermal decomposition temperature is 300 ° C. or higher, and the highly reactive organic solvent generates reaction heat, which causes ignition and combustion of the sheet. It should preferably be something that is difficult to get rid of. For example, phosphate-based binders such as sodium hexametaphosphate and silicate-based binders such as sodium silicate are preferred.

It is not necessary to use the same kind of binders for the inorganic binder that fixes and maintains the adsorbent and the constituent fibers, and the inorganic binder that fixes and maintains the flute portion 200a and the liner portion 200b that constitute the honeycomb. It is desirable to use

In this embodiment, the frame body 30F1 has a generally box-like form as a whole so as to form an inflow side opening and a discharge side opening. Inwardly bent flanges 34 are provided at the inflow side opening and the discharge side opening of the pair of side plates 33 positioned on the left and right. Inwardly bent flanges 32 are also provided around the entire perimeter of lid members 31 arranged vertically.

When stacking the adsorption elements 200 at the time of assembling the adsorption unit 30 or when cleaning or replacing the adsorption elements 200 after the adsorption unit 30 is assembled, the frame body 30F1 may be divided. In joining using welding, once the suction unit 30 is assembled, it is difficult to divide it. In the case of screw/bolt fastening, it can be easily disassembled. However, it is necessary to secure the volume of the screws and bolts, resulting in unnecessary thickness.

Therefore, it is preferable to use the rivet 37 as the fastening member because it can be easily disassembled and requires only a small volume. A member fixed with the rivet 37 is provided with a through hole in advance. If there is no problem even if the volume increases, screws, bolts, or the like may be used as the fastening member. In the drawing, in order to clarify the mounting position of the rivet 37, the ratio is different from the actual size.

In order to increase the opening area of the frame 30F1, it is preferable that the material used for the frame 30F1 is thin, but it is also necessary to maintain the strength of the structure. It may be appropriately set in consideration of these. The frame 30F1 and the rivets 37 need only have sufficient strength, heat resistance, chemical resistance, etc. under the conditions of use. A metal material such as iron, stainless steel, or aluminum, or a resin material such as acrylic, bakelite, or melanin may be used.

Alternatively, a configuration in which the number of laminated bodies 200A is simply increased may be employed, but contact or rubbing between the laminated bodies 200A may damage the adsorption element 200. FIG.

Therefore, as shown in the present embodiment, partitions 35 are arranged between the laminates 200A. The partition 35 is provided so as to extend from the inflow side opening to the discharge side opening, and divides the laminate 200A. By arranging the partitions 35, it is possible to suppress contact and rubbing between the laminates 200A. Furthermore, since the adsorption element 200 can also be held by the partition member 35, the structural stability of the layered body 200A can be increased. Since the laminate 200A is fixed by the frame 30F1 and the partition 35, the adsorption elements 200 forming the laminate 200A do not need to be fixed with an adhesive, but may be fixed with an adhesive. good.

The number of layers in the layered body 200A and the number of partitions 35 can be appropriately changed according to the strength and performance required of the adsorption unit 30. It is preferable to provide the partitions 35 so as to divide the area into 2 to 5 parts.

The agent used for the partition body 35 should have sufficient strength, heat resistance, chemical resistance, etc. under the same usage conditions as the frame body 30F1 and the like.
