Description of the Related Art In the prior art of a gas adsorption and decomposition filter having a three-dimensional network skeleton structure, Japanese Patent Publication No. 4-35201 discloses a method in which a deodorant is fixed with an organic binder based on an organic filter base material. Although there is a deodorizing filter described in the official gazette, it is composed of organic materials with low heat resistance, so it removes harmful gas components discharged from garbage incinerators and automobiles, etc. It could not be used for applications in which it is reactivated in a state because it does not have heat resistance.

温状態で再活性させて用いることも出来なかった。A filter having a three-dimensional reticulated skeleton structure has a low air permeability due to its structural characteristics, has a high internal filtration function, has a high contact efficiency with gas components, and is optimal as a filter structure. . However, since the filter base material of the three-dimensional reticulated skeleton structure is composed of an organic material such as polyurethane foam, nylon, polypropylene, or polyester, there is a problem in heat resistance, and in applications where heat resistance is required as described above, It could not be applied, nor could the gas component once adsorbed and saturated be reactivated at high temperatures for use.

る。BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the present inventors have proposed a method for improving the heat resistance of a three-dimensional networked skeleton structure by embedding the three-dimensional networked skeleton structure in a polyurethane foam or resin net skeleton. By firing in advance using an inorganic firing material, a filter base material with high heat resistance can be obtained, and in applications where it is used at a relatively low temperature, the organic base material having a three-dimensional reticulated skeleton structure is thermally degraded. It has been found that even if the strength is somewhat lost, the filter strength can be maintained by an inorganic material bound by a heat-resistant binder component formed on the skeleton of the three-dimensional network skeleton structure. In addition, based on these technologies, a three-dimensional reticulated skeleton with high heat resistance is obtained by fixing a deodorant having gas adsorption performance and decomposition performance on a three-dimensional reticulated skeleton structure with an inorganic binder. We can supply a deodorizing filter with a structure.

The deodorizing performance was evaluated under the conditions of the min. ventilation method, and a standard gas of benzene 100 ppm was ventilated until the benzene removal rate became 0%. Thereafter, in order to conduct a recovery performance test of the deodorizing performance, the sample after the evaluation of the deodorizing performance was subjected to 200 ° C.
× 5Hr. After leaving to stand, and further cooling for 60 minutes in a clean room temperature environment free from the influence of other gas components, the same deodorization performance evaluation as described above was performed again. The recovery rate of the deodorizing performance was calculated by calculating the area integrated value of the adsorption curve of the initial deodorizing performance and 200 ° C. × 5.
The recovery rate of the benzene deodorizing performance was determined from the area integrated value of the adsorption curve after the re-deodorization test by leaving Hr. In the sample of the comparative example, the adhesive strength of the binder was deteriorated by leaving the sample at 200 ° C. for 5 hours. Due to the influence of the activated carbon falling off and the generation of the pyrolytic gas, the recovery rate of the deodorizing performance of the comparative example is significantly lower than those of the examples 1 and 2 and is not suitable in terms of heat regeneration. You can see that.
