ルタに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing filter which is used in air conditioners and air purifiers for removing bad odors in a closed space, has high deodorizing performance, and can remove tobacco odor.

Description of the Related Art Generally, a deodorizing agent for a deodorizing filter used in an air conditioner and an air purifier is mainly made of activated carbon, and powdered activated carbon or granular activated carbon is attached to the surface of the filter. The air containing the bad smell in the closed space passes through the filter surface, thereby removing the bad smell in the closed space.

着されにくいからである。However, activated carbon, which is the main raw material of the deodorant attached to the conventional deodorizing filter, has a problem that the effect of removing the tobacco odor is not sufficient. This is because the deodorizing mechanism of activated carbon is based on the fact that molecules that cause the odor are physically adsorbed in the pores on the surface of the activated carbon. This is because ammonia and acetaldehyde, which are polar molecules, are not easily adsorbed on activated carbon.

る。[0004] Further, since activated carbon has a small specific gravity, a large amount of activated carbon is required to increase the weight of malodor molecules adsorbed on activated carbon on the filter surface. Then, in order to attach the deodorant containing a large amount of activated carbon to the filter surface without falling off, a large amount of a binder must be used. As a result, the surface of the activated carbon is covered with the binder, and the deodorizing ability of the activated carbon is significantly reduced.

As a result, a conventional deodorizing filter was obtained by attaching a deodorizing agent containing high silica zeolite and a transition metal oxide to a porous substrate. Found that tobacco odor, which had insufficient deodorizing effect, could be removed.

ることができる。In the present invention, a high silica zeolite and a transition metal oxide are used as a deodorizing agent for a deodorizing filter. The high silica zeolite has an excellent effect of removing polar molecules such as ammonia and acetaldehyde. Further, the transition metal oxide has an excellent effect of removing sulfur-based malodorous molecules such as methyl mercaptan and hydrogen sulfide. Therefore, a deodorizing filter having excellent deodorizing performance can be obtained by combining these deodorizing agents. As a result, as compared with the performance of a conventional deodorizing filter using activated carbon, if the deodorizing performance is equivalent, the present invention can reduce the amount of the deodorizing agent attached to the porous substrate. Therefore, it can be made thinner than a conventional deodorizing filter.

On the other hand, when the ratio of the high silica zeolite in the deodorant exceeds 95% by weight, the effect of removing sulfury malodorous molecules such as methyl mercaptan and hydrogen sulfide decreases. Therefore, the ratio of high silica zeolites and transition metal oxides in deodorants, high silica zeolite 40 to 95 wt%, the transition metal oxide is desirably 5 to 60 wt%.

The weight ratio of the 1 component (Si component: Al component) is 10: 1 to 50: 1, and it is particularly preferable to use a high silica zeolite having a weight ratio of 40: 1 to 50: 1.

It can be arbitrarily selected from various oxides such as Mn or Fe, but from the viewpoint of deodorizing performance, it is desirable to use a Cu-Mn-based composite oxide, an Fe-Mn-based composite oxide, or a Mn oxide.

On the other hand, when activated carbon is added, a more excellent effect of removing acetic acid molecules is exhibited.

ルターを薄くすると共に、経済性の点で望ましい。In the present invention, a deodorant is attached to a porous substrate. In general, a porous substrate is a general term for a substrate having a large number of holes through which gas can pass through its surface, such as a porous synthetic resin, a polyurethane foam, a nonwoven fabric, a loop-shaped laminate, or a ceramic. , Can be arbitrarily selected from various honeycombs made of metal, paper or resin.However, when a net-like synthetic resin, polyurethane foam or non-woven fabric is used for the porous substrate, the deodorizing filter can be made thinner and economical. desirable.

選択できる。If the amount of the deodorant attached to these porous substrates is less than 10 g / m 2 , the deodorizing performance is insufficient, and if the amount of the deodorant exceeds 1000 g / m 2 , excellent deodorization is achieved. Although it exhibits performance, it has a ventilation resistance of 10 mmAq or more, and is not suitable for use as a filter. Therefore, the amount of the deodorant to be attached to the porous substrate is 10 to 1000 g / m 2. The range can be arbitrarily selected depending on the deodorizing performance, ventilation resistance and economy required for the deodorizing filter to be used.

The removal rate of molecules was evaluated as deodorizing performance. However, zeolites and transition metal oxides used high silica zeolites and Cu-Mn-based oxides which showed the best deodorizing effects in the evaluations of Tables 1 and 2, and other conditions were set in the same manner as in Table 1. did. The amount of the deodorant to be attached to the porous substrate was 250 g / m 2 . The evaluation results of these deodorizing performances are also shown in Table 3 below.

Low. Also,
In Comparative Example 4, since the deodorizing agent was entirely composed of zeolite, there was no effect of removing hydrogen sulfide. On the other hand, Example 1
And Nos. 7 to 12 exhibited good deodorizing performance for all malodorous molecules because the weight ratio of zeolite and transition metal oxide in the deodorizing agent was within the range of the present invention.

Similarly to the evaluations shown in Tables 1 to 3, the removal rate of the malodorous molecules was evaluated as the deodorizing performance. However, powdered activated carbon of 100 mesh or less was used as activated carbon. The evaluation results of these deodorizing performances are also shown in Table 4 below.

When a high-silica zeolite is used as a deodorant and a chemisorption-type deodorant or activated carbon is added to the deodorant, the deodorizing effect is further improved. When a net-like synthetic resin, polyurethane foam or nonwoven fabric is used for the porous substrate, the production cost is low and the deodorizing filter can be made thin.
