Abstract

(57) [Summary] Activated carbon, synthetic zeolite and the like have been conventionally used for absorbing moisture, deodorizing or purifying air. Activated carbon has a deodorizing property, but it is difficult to desorb adsorbed odorous gas and has no hygroscopic property. Synthetic zeolites are excellent in hygroscopicity and deodorization, but relatively expensive. As the shape of the material for moisture absorption, deodorization, or air cleaning, powder or granule has a problem that the pressure loss in the air is large and the rate of moisture absorption or deodorization is low. The main structure of the present invention is to mix an inexpensive artificial zeolite with a binder and then injection-mold the same, and use a honeycomb-shaped artificial zeolite structure for absorbing moisture, deodorizing or cleaning air, or using the same. The present invention relates to a molded artificial zeolite structure.

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

[Prior art]

 Activated carbon, synthetic zeolite, and the like have been conventionally used for absorbing moisture, deodorizing, or purifying air. Activated carbon has a deodorizing property, but it is difficult to desorb adsorbed odorous gas and has no hygroscopic property. Synthetic zeolites are excellent in hygroscopicity and deodorization, but relatively expensive. The shape of the material for absorbing moisture, deodorizing, or cleaning air is generally powder or granule, but recently a honeycomb structure has been proposed. For example, as an example of a deodorizing filter, a public utility model Heisei 5-22022 (honeycomb structure). Examples of the adsorptive honeycomb-shaped ceramic body include Utility Model Registration No. 3074667 (a honeycomb structure containing a functional material).

On the other hand, artificial zeolites obtained by chemically treating materials such as coal ash, municipal waste incineration ash, and aluminum dross have been separately proposed. The artificial zeolite can be obtained by performing a chemical reaction by heating in an aqueous alkaline solution such as caustic soda. The resulting artificial zeolite is excellent in hygroscopicity and deodorization.

[Problems to be solved by the invention]

 As described above, a zeolite molded structure suitable for use in absorbing or deodorizing or purifying air has deodorizing or hygroscopic properties, and can be desorbed (regenerated). Inexpensive materials with few are required. As for the shape of the material for moisture absorption, deodorization, or air cleaning, powder or granule has a problem that the pressure loss in the air is large and the rate of moisture absorption or deodorization is low.

[0005] In general, zeolite is porous having angstrom unit pores and is excellent in adsorptivity and cation exchange ability. Most zeolites are hydrophilic, but can be made hydrophobic by changes in composition or structure. There are three types of zeolites: natural zeolites, synthetic zeolites, and artificial zeolites. Natural zeolites are contained in tuff and contain many impurities, and have low adsorption and cation exchange performance. Synthetic zeolites are pure zeolites that do not contain impurities of chemical synthesis, and are excellent in hygroscopicity and deodorization, but relatively expensive to manufacture.

[0006] Zeolites have a large number of pores, which facilitate the adsorption of gaseous substances. In addition, zeolite has a characteristic that is not found in activated carbon, and the adsorbed gas can be easily removed with hot or hot air.

[0007] The artificial zeolite is mainly composed of amorphous aluminum silicate in incinerated ash such as coal ash, municipal refuse incineration ash, and aluminum dross, and is obtained by porous crystallization. Adsorption capacity and cation exchange capacity are comparable to synthetic zeolites, but they can be manufactured at relatively low prices. An object of the present invention is to utilize an artificial zeolite having such various characteristics.

[0008] The shape of the material for deodorization, adsorption, or air cleaning may be powdery or granular. The powder is used after being applied to a cloth or the like, and the granules are used after being filled in a container or the like. These have a small contact area with the gas and have poor adsorption or deodorization efficiency. Also, the pressure loss is large in the flowing air, and the rate of moisture absorption or deodorization is low.

[0009]

[Means for Solving the Problems]

 An object of the present invention is to solve the above-mentioned various problems at once, and to provide a honeycomb-shaped artificial zeolite structure excellent in moisture absorption, deodorization, or air cleaning action. Since the honeycomb shape has a large contact area with the gas and a small pressure loss in the flowing air, the rate of moisture absorption or deodorization is high.

[0010] More specifically, the present invention comprises various forms of the above-mentioned and its applications.
