【Example】

Hereinafter, the present invention will be explained in more detail with reference to the accompanying drawings.

[0009] FIG. 1 is an exploded perspective view showing an embodiment of the present invention, and FIG. 2 shows the adsorption device of the present invention. FIG. 3 is a cross-sectional view showing the attached processing device.

0010 The adsorbent 1 is a tapered cone made of activated carbon fibers and a binder. It is shaped like a table and has an elastic paper structure.

[0011] Activated carbon fibers can be obtained by activating carbon fibers such as polyacrylonitrile, phenol resin, cellulose, rayon, and pitch. The specific surface area of activated carbon fibers is, for example, about 500 to 2,500 m ² /g, and due to its unique micropore structure, it is characterized by high adsorption rate and adsorption capacity. Note that the activated carbon fiber may be used in combination with powdered or granular activated carbon.

0012 In addition, examples of the binder include pulp; heat-melt synthetic fibers; heat-melt synthetic fibers; Examples include synthetic resins. The heat-melting synthetic fibers include, for example, polyethylene, Examples include polypropylene, polyvinyl alcohol, and polyacrylonitrile. Ru. Examples of heat-melting synthetic resins include olefins such as polyethylene and polypropylene. Fin polymer, polyvinyl acetate, polyvinyl alcohol, polyester, Commonly used iron, acrylic resin, polyacrylonitrile, styrenic polymer, etc. thermoplastic polymers can be used. The form of the binder depends on the method of manufacturing the adsorbent. It can be in powder, granular, or fibrous form, but activated carbon It is preferable that the fiber is in the form of a fiber that can suppress clogging of micropores in the fiber. particularly preferred The binder is pulp and/or thermobondable fiber. These binders are One or more types can be used.

[0013] The adsorbent 1 may contain reinforcing fibers in addition to the above-mentioned components. As a reinforcing fiber For example, natural fibers such as cotton and hemp; aromatic polyamide fibers, aromatic polyester Synthetic fibers such as polyester fibers; Semi-synthetic fibers such as rayon; Glass fibers, carbon fibers, aluminum Examples include inorganic fibers such as mina fibers and metal fibers. These reinforcing fibers are one type or Two or more types can be used.

[0014] The content of activated carbon fiber is, for example, 50 to 99% by weight in the adsorbent 1, preferably is about 90 to 99% by weight, more preferably about 95 to 99% by weight.

[0015] The adsorbent 1 contains a dispersant, a stabilizer, etc. within a range that does not adversely affect the adsorption capacity and strength. agent, viscosity modifier, anti-settling agent, thickener, filler, paper strength enhancer, and flocculant. Contains various additives such as surfactants, especially polymer flocculants and retention aids. It's okay.

[0016] The adsorbent 1 is attached to a case 2 and constitutes an adsorption device. This case 2 is It consists of a case body 3 and a lid body 5 that closes the opening of this case body 3. . The lid body 5 is formed with an inflow part 6 through which the liquid to be treated flows, and the case body 3 is formed with an outflow portion 4 through which the liquid to be treated that has been processed by the adsorbent 1 flows out. There is. Note that the side wall of the case body 3 is slightly inclined outward and formed in a tapered shape. ing. The case body 3 and the lid body 5 are tightly attached to each other by screwing, welding, adhering, etc. to be integrated into.

[0017] In order to improve the attachability to the case body 3, the case body 1 has a truncated conical shape. The diameter D1 of the end on the insertion side into the case body 2 is such that it can come into contact with the inner wall of the case body 3, i.e. That is, the inner diameter of the opening of the case body 3 is larger than the inner diameter D3 of the bottom of the case body 3. smaller than D4 (D3 < D1 < D4). The diameter D2 of the other end of the adsorbent 1 is In this example, it is formed approximately equal to the inner diameter D4 of the opening of the case body 3. Also , the height H of the truncated conical suction body 1 is set in order to fit it tightly into the case 2 by pushing. 1 is greater than the height H2 of the case body 3. In other words, the volume of adsorbent 1 is is larger than the volume of space 2.

[0018] When attaching such an adsorbent 1 to the case 2, one end of the adsorbent 1 is Since the diameter D1 is smaller than the inner diameter D4 of the opening of the case body 3, the smaller diameter end is It can be easily attached to the case body 3 toward the bottom side of the case body 3. In addition, adsorbent 1 has elasticity, so the adsorbent 1 is compressed when inserted into the case body 3. It comes into contact with the inner wall of the case body 3 and comes into close contact with the inner wall of the case 2. Moreover, the adsorbent 1 has a paper structure with high air permeability and liquid permeability, so even if it is in close contact with case 2, There is no reduction in adsorption processing efficiency.

[0019] As long as the adsorbent can be attached tightly to the case, the diameter of one end should be the same as the case. It is sufficient that the adsorbent can make contact with the inner wall of the case and that the volume of the adsorbent is larger than the volume of the case. . The volume of the adsorbent can be set according to the volume of the case. For example, the volume of the adsorbent can be set depending on the case. It is sufficient if it can be compressed by about 30%. For example, as in this embodiment, the height of the adsorbent 1 is The adsorbent 1 may be compressed by making the height larger than the case body 3, and the case body 3 may be compressed. Compression may be achieved by providing a protrusion on the lid 5 of the base 2. As a result, elasticity The adsorbent has 70-95% of its original volume when installed in the case. compressed into a product.

[0020] The shape of the adsorbent may be any three-dimensional shape that corresponds to the shape of the case, and is limited to a truncated cone shape. It may also be in the shape of a truncated pyramid. In addition, if the adsorbent is in the shape of a truncated pyramid, the diameter of both ends means average diameter. The sides of the preferred adsorber are tapered to make it easier to install. - shaped.

[0021] When used for the treatment of clean water, an adsorption device composed of the adsorbent 1 and the case 2 For example, as shown in FIG. The water flowing into the case body 3 from the inflow part 6 passes through the adsorbent 1. , extracted as filtered water.

[0022] In addition, if necessary, in the adsorption device shown in Figure 2, the fluid may be allowed to flow from the bottom to the top. It's okay. At this time, the outflow section 4 becomes the inflow section, and the inflow section 6 is used as the outflow section. It will be done.

[0023] In addition, as shown in FIG. itself, with the large diameter opening side of the case body 13 closed by the lid body 15 facing downwards. Alternatively, the case body 13 can be used with the smaller diameter bottom side facing upward. this state In this case, the inflow section 16 may be provided above the adsorption device, and the outflow section 14 may be provided below the adsorption device. Alternatively, the inflow portion and the outflow portion may be provided on vertically opposite sides. In this case The expression "bottom of the suction device" means the side opposite to the opening of the case body 13, This also includes the case where it is located at the top of the adsorption device.

[0024] The suction device of the present invention can be installed not only in the processing device with the structure shown in the figure, but also in a variety of other devices. Wear.

[0025] In addition to the adsorption device, the applicant has proposed a case with a “fluid inlet and outlet”. An elastic adsorbent containing activated carbon fibers and a binder is housed in a circular It is formed in the shape of a truncated pyramid or a truncated pyramid, and the end with a small diameter can come into contact with the inner wall of the case. Also disclosed is an adsorbent body formed in a diameter.

[0026] The adsorbent is formed into an adsorbent in a slurry containing activated carbon fibers and a binder. A large number of small holes are formed corresponding to the shape and regulating the passage of components in the slurry. A molding suction mold having a recessed part is sucked, and components in the slurry are deposited in the recessed part. . Next, the wet molded body formed in the recess is heated and dried to combine with the activated carbon fibers. It can be obtained by joining with an inner. Application of molded adsorber in wet state Thermal drying can be performed, for example, at a temperature of about 100 to 200°C.
