Is done. Next, the adsorbed malodorous substance is effectively decomposed and deodorized by its catalytic action, as the metal phthalocyanine polycarboxylic acid represented by the formula (1) is called an artificial enzyme.

Further, it has a characteristic that the specific surface area and the pore volume are very large as compared with conventional activated carbon. Therefore, since the adsorption efficiency and adsorption capacity of the offensive odor substance are much larger than those of the conventional art, the adsorption and removal performance of various odor substances can be enhanced. Further, since the chance of the metal phthalocyanine polycarboxylic acid coming into contact with the malodorous substance increases, the deodorizing performance is enhanced.

ない。Here, when the metal phthalocyanine polycarboxylic acid was used in the same content ratio as in the prior art, it was recognized that the deodorizing performance was improved more than expected from the effect of the activated carbon fiber. This is because the activated carbon fiber has a very large specific surface area and a very large pore volume, so that the uneven distribution of the metal phthalocyanine polycarboxylic acid is alleviated and supported so as to be uniformly dispersed, and the effective metal phthalocyanine polycarboxylic acid which can be brought into contact with the malodorous substance. One reason is that the carboxylic acid is increased as compared with the conventional case. However, the mechanism of action is not limited to this.

It is possible to further improve the deodorizing performance while reducing the size of the body. Further, since the activated carbon fiber has an extremely high adsorption speed as compared with conventional activated carbon, malodorous substances are quickly adsorbed and removed, and immediate deodorization becomes possible.

Therefore, it becomes easy to process the deodorant structure into members having various shapes such as a sheet, a honeycomb structure, a bellows, and a corrugated plate. Furthermore, since the metal phthalocyanine polycarboxylic acid functions as a catalyst in the decomposition reaction of the malodorous substance, it does not consume itself. Further, the metal phthalocyanine polycarboxylic acid is stable against acids and alkalis and is excellent in weather resistance, heat resistance and moisture resistance, so that a stable deodorizing effect can be obtained. Rather, since the metal phthalocyanine polycarboxylic acid has a carboxyl group in the molecule and is water-soluble, the efficiency of decomposing malodorous substances is further enhanced by moisture absorption.

When the metal coordinated with the phthalocyanine polycarboxylic acid is cobalt, the catalytic activity is enhanced as compared with the metal phthalocyanine polycarboxylic acid coordinated with another metal. As a result, the rate of the decomposition reaction of the malodorous substance increases, and the decomposition efficiency of the malodorous substance is further enhanced.

ただし、作用機序はこれに限定されるものではない。Further, it is preferable that activated carbon is further contained as an adsorption medium. When the deodorant structure thus configured was used, improvement in deodorant performance was confirmed as compared with the case where only activated carbon fibers were included and the case where only activated carbon was included.
This is considered to be due to a synergistic effect between the activated carbon fiber and the activated carbon. Activated carbon has pores with different pore sizes, called macropores, mesopores, micropores, and submicropores, mixed from the larger pore size, and the average pore size and pore size distribution width are larger than those of activated carbon fibers. I have. Therefore, it is presumed that the combined use of activated carbon improves the adsorption performance for malodorous substances having a molecular diameter larger than the pore diameter of the activated carbon fiber, and enhances the deodorant performance.
However, the mechanism of action is not limited to this.

The pore size of such a size is almost equal to or slightly larger than the molecular diameters of typical malodorous substances such as ammonia, acetaldehyde, methyl mercaptan, trimethylamine, hydrogen sulfide and ethanethiol, so that these malodorous substances are absorbed very efficiently.

More preferred. In the deodorant structure thus configured, the following effects are exhibited by the synergistic effect of the combustible fibers such as pulp and the adsorption medium. That is, the activated carbon fiber, which is the adsorption medium, and the activated carbon are integrated with the flammable fiber and are held well, and the handleability of the deodorant structure is improved. Further, by using the combustible fiber, the deodorant structure can be discarded as a combustible material. Furthermore, since the adsorption medium is mixed with the combustible fibers and appropriately dispersed in the deodorant structure, the adsorption efficiency of the malodorous substance is further improved.

For example, it is more preferable to be processed into a corrugated shape like a so-called corrugated plate. By doing so, the effective surface area per volume of the deodorizing structure is increased, so that the deodorizing performance can be further improved and the deodorizing structure can be downsized. Further, since the space can be defined by the corrugated shape, the air permeability is enhanced, and the deodorizing performance can be further enhanced. In addition, the corrugated shape has excellent strength characteristics. For example, the space is less likely to be deformed or crushed even when it is stacked in multiple stages during storage or the like.

According to the deodorant configured as described above, the gas containing the malodorous substance reaches the deodorant structure inside the housing through the vent hole and is adsorbed and decomposed. As described above, the deodorizing performance of the deodorizing structure of the present invention is significantly improved as compared with the related art, so that a sufficient deodorizing effect can be obtained in an environment where a deodorant is installed. .

A malodorous substance is adsorbed by the pores formed in the activated carbon fiber and deodorized.

Further, it has a characteristic that the specific surface area and the pore volume are very large as compared with conventional activated carbon. Therefore, since the adsorption efficiency and adsorption capacity of the offensive odor substance are much larger than those of the conventional art, the adsorption and removal performance of various odor substances can be enhanced. In addition, since the chance of the metal phthalocyanine polycarboxylic acid coming into contact with the malodorous substance increases, the deodorizing performance is enhanced. Therefore, by using the deodorant structure 1, a sufficient deodorizing effect can be obtained.

If the average pore diameter is less than 1 nm, these malodorous substance molecules tend to hardly enter the pores. On the other hand, when the average pore diameter exceeds 4 nm, it is considered that desorption of the malodorous substance molecules entering the pores competes with the adsorption.

Moreover, when the deodorant structure 1 also contains activated carbon having a larger average pore diameter and a larger pore diameter distribution width than activated carbon fibers, malodorous substances having a molecular diameter larger than the activated carbon fibers are present. Also, a sufficient deodorizing effect can be obtained. Furthermore, since the activated carbon fiber is of a petroleum pitch type and has a characteristic that the regeneration loss due to adsorption and desorption is small and the purity of carbon is high, the deodorizing performance of malodor is further enhanced.

れるので、即効性のある消臭が可能となる。Furthermore, since the specific surface area and the pore volume of the activated carbon fiber are very large, the metal phthalocyanine polycarboxylic acid represented by the formula (1) is hardly unevenly distributed, is supported so as to be uniformly dispersed, and has a bad odor. Effective metal phthalocyanine polycarboxylic acids that can come into contact with substances tend to increase as compared with the prior art. Therefore, the deodorizing performance is improved more than expected from the improvement of the adsorption performance by the activated carbon fiber. As a result, the required amounts of both the adsorption medium (activated carbon fiber) and the catalyst (metal phthalocyanine polycarboxylic acid) can be reduced as compared with the conventional case. Therefore, the deodorizing structure 1 can be made compact to save space, and a more excellent deodorizing effect can be obtained. Furthermore, the activated carbon fiber has a characteristic that the adsorption rate is much higher than that of conventional activated carbon, and the malodorous substance is quickly adsorbed and removed, so that an immediate deodorization is possible. .

It is retained and has excellent handleability. This effect is the same even when activated carbon is contained. Further, since the deodorant structure 1 is mainly composed of fibers such as activated carbon fibers and pulp, it is excellent in workability into various shapes such as sheets 11 and 12 such as sheets, honeycombs and bellows. Furthermore, since the deodorant structure 1 is flammable, disposal is simple and the volume reduction by incineration is enhanced. Further, since the activated carbon fibers are mixed with the pulp and are appropriately and satisfactorily dispersed in the deodorant structure 1, the adsorption efficiency of the malodorous substance is further enhanced. Therefore, the deodorant performance of the deodorant structure 1 is further enhanced, and a more excellent deodorant effect can be obtained.

With these, the deodorant performance of the deodorant structure 1 is further enhanced. Therefore, the deodorizing effect of the deodorizing structure 1 can be further improved. In addition, the deodorant structure 1 can be made more compact, and the deodorant structure 1
Can further reduce the installation space. In addition, the corrugated shape has excellent strength characteristics, so it is difficult to deform or crush even if it is stacked in storage or shock from the outside, and the defined space is retained and good deodorant performance Can be maintained.

られる。Further, the metal phthalocyanine polycarboxylic acid functions as a catalyst in a decomposition reaction of a malodorous substance, and is not consumed by itself. Therefore, a sufficient deodorizing effect can be maintained for a long time. In addition, metal phthalocyanine polycarboxylic acids are stable to acids and alkalis, are excellent in weather resistance and heat resistance, are soluble in water, and are excellent in moisture resistance. Therefore,
A stable deodorizing effect is obtained. Rather, the effect of decomposing malodorous substances by the metal phthalocyanine polycarboxylic acid is enhanced by absorbing moisture. Therefore, even when the deodorant structure 1 is applied to a location with high humidity, a sufficient deodorant effect can be obtained.

1 (inflow). The gas entering the case 21 diffuses around the deodorant structure 1, and the malodorous substances in the gas reach the deodorant structure 1 and are quickly adsorbed on the activated carbon fibers. When the deodorant structure 1 also contains activated carbon, the malodorous substance is also adsorbed on the activated carbon. The adsorbed malodorous substance is rapidly decomposed by the catalytic action of the metal phthalocyanine polycarboxylic acid, and the surrounding odor is quickly deodorized.

Since the deodorizing performance of the deodorant structure 1 is significantly improved as compared with the related art, a sufficient deodorizing effect can be obtained for the environment where the deodorant 2 is installed. Further, since the deodorizing structure 1 can be downsized while maintaining good deodorizing performance, the case 21 can be made compact. As a result, the installation space for the deodorant 2 can be reduced to save space. Therefore, it is very useful when applied to a place where storage space or the like is desired to be secured as much as possible. Further, since the case 21 is made of paper, the entire deodorant 2 becomes combustible. Therefore, disposal of the deodorant 2 is simplified, and the volume reduction by incineration can be improved.

Therefore, from these results, the deodorizing structure according to the present invention using activated carbon fibers can exhibit superior deodorizing performance as compared with the conventional deodorizing structure using activated carbon, and the effect is particularly significant when the elapsed time is long. It was confirmed that it became remarkable. Further, the ethanethiol removal rates at the time of 72 hours and 168 hours in Example 13 are substantially equal to the values at the time of 168 hours and 240 hours of Comparative Example 5, respectively. Therefore, it is understood that the deodorant structure according to the present invention is superior to the conventional one also from the viewpoint of the immediate effect of the deodorant effect.

It was about 1/2 of 10. This result indicates a removal rate proportional to the content of the activated carbon fiber. However, when the elapsed time was 72 hours or more, the removal rate was much higher than the removal rate estimated from the ratio of the activated carbon content, and the content of the adsorption medium was twice that of Example 15; It was confirmed that they showed equivalent values. From this, it is understood that the deodorant structure of the present invention containing activated carbon fibers has extremely high deodorant performance.
