布均一性が損なわれる。As a method of processing the photocatalyst into the binder, it is preferable to use, for example, a method in which a coating agent containing titanium oxide is added to the binder and dried. The coating agent contains, for example, a photocatalyst such as titanium oxide and an inorganic adhesive such as a silicate-based adhesive, and more preferably has a solid content of 3 to 40% by weight. When the ratio of titanium oxide is 10 to 9
It is preferably 0% by weight. If the solid content is less than 3% by weight, the desired effect cannot be expected because the photocatalyst such as the coating agent is not uniformly dispersed on the binder surface, while if it exceeds 40% by weight, the coating uniformity is impaired due to an increase in the viscosity of the coating agent. It is.

る。Further, if the ratio of the photocatalyst such as titanium oxide in the solid content is less than 10% by weight, the effect of the catalytic action is small, and it cannot be expected that the desired reaction is sufficiently exhibited. When the content exceeds 90% by weight, the content of the adhesive is small and the adhesiveness is poor, so that the adhesive is easily peeled off, and there is a possibility that the photocatalyst may be scattered in a powder form after the processing.

ある。The amount of the photocatalyst contained in the filter is preferably 1 to 10% by weight based on the adsorbent. If the content is less than 1.0% by weight, the content of the photocatalyst is insufficient, and it is difficult to uniformly distribute the photocatalyst. Therefore, the desired reaction cannot be sufficiently obtained.
If the amount exceeds 10% by weight, even if it is further increased, the improvement of the regenerating effect due to the decomposition of the deodorizing component by the photocatalyst cannot be confirmed.

In this case, proximity or contact means that the effect is obtained by being located in the vicinity of the adsorbent, unlike the one adhering to and supporting the adsorbent by an inorganic adhesive. That is, in FIG. 3, the photocatalyst is present in the binder 6 which exists between the nonwoven fabric fiber 5 and the adsorbent 4 and connects the two, and this state occurs when the photocatalyst and the adsorbent approach or come into contact with each other. It is in the state that it is.

や、ガス濃度、流量等に依存するものである。Next, the process of adsorbing, removing and decomposing gas in the air passing through the air conditioner will be described. First, the adsorbent of the filter in the air conditioner flows through the air conditioner to adsorb and remove odor components in the air passing through the filter. At this time, the adsorption capacity of the adsorbent depends on the number of adsorption sites, gas concentration, flow rate, and the like.

能となる。Next, the gas adsorbed by the adsorbent moves and reaches the photocatalyst. If the photocatalyst is activated by irradiating light, a reaction takes place and the gas is decomposed. As a result, the adsorption site of the adsorbent in the air conditioner becomes vacant, and it is possible to continuously adsorb and remove odor components.

部や吸着材間のガス濃度差によると推定される。The mechanism by which the adsorbing ability is improved by mixing the adsorbent such as activated carbon with the photocatalyst is presumed as follows. The gas adsorbed by the adsorbent is considered to be desorbed and re-adsorbed instead of being fixed to the adsorption site, and the driving force for moving the adsorbed gas is the gas inside the adsorbent or between the adsorbents. Presumed to be due to density differences.

吸着性能が再生する。On the outer surface of the adsorbent, the photocatalyst contained in the binder exists near the adsorbent, and the gas adsorbed by the adsorbent can move to the photocatalyst. When the gas transferred to the photocatalyst is decomposed, a concentration difference occurs between the adsorbent and the photocatalyst, and further gas transfer occurs. By the continuation of this process, the adsorption performance of the adsorbent of the filter in the air conditioner is regenerated.
