The invention described, wherein the light source is disposed upstream of the upstream filter, and the upstream filter has a configuration in which a photocatalyst is present more upstream than the metal oxide or the metal composite oxide. . The oxidative decomposition by the photocatalyst is due to OH radicals generated on the photocatalyst surface by irradiation with ultraviolet rays. The amount of generated OH radicals depends on the intensity of ultraviolet light, and the higher the intensity of ultraviolet light, the more OH radicals are generated, thereby improving the efficiency of oxidative decomposition. Since the ultraviolet intensity is inversely proportional to the distance, it is necessary to bring the light source and the photocatalyst closer in order to improve the efficiency of oxidative decomposition. Further, since the gaseous substance is gradually adsorbed from the upstream side, it is adsorbed at a higher concentration in the upstream side. Therefore, it is generated by disposing the light source on the upstream side of the filter and increasing the amount of the photocatalyst on the surface of the upstream side so that the ultraviolet intensity in the upstream portion of the filter to which a large amount of gaseous substances is adsorbed is increased. The amount of OH radicals can be increased, and the efficiency of oxidative decomposition is increased. The gaseous substance adsorbed on the downstream portion of the filter is also oxidatively decomposed and removed from the gaseous substance on the upstream side, moves to the upstream side by the concentration gradient, and is similarly oxidized and decomposed by the photocatalyst.

臭性能がより向上したものと考えられる。Next, an experiment will be described in which the deodorizing performance of the air purifying apparatus of the present embodiment is compared between the air purifying apparatus of the first embodiment and an air purifying apparatus equipped with a filter using only activated carbon. The three types of air purification devices were placed in a 6 m 3 test box, and the concentrations of ammonia and hydrogen sulfide were adjusted to 20 ppm in the test box. The air volume of the fan of the blowing means 9 is set to 3 m 3 / min,
The ammonia concentration and the hydrogen sulfide concentration in the box were measured. The heater 12 of Example 2 was energized at 100 W for only 5 minutes from the start. FIG. 4 shows the change over time of the ammonia concentration.
FIG. 5 shows the change over time of hydrogen sulfide. In Examples 1 and 2, the gas concentration decayed faster than in the filter using only activated carbon. In particular, for hydrogen sulfide, only activated carbon was removed in 60 minutes and the removal rate was 5%.
%, Whereas Examples 1 and 2 reached 5% or less before 10 minutes, and the deodorizing speed was about 6 times. In addition, comparing Example 1 and Example 2, Example 2 was more excellent in removal performance. This is presumably because manganese oxide and copper oxide were heated and activated by the heater 12 serving as a heating means, and exhibited a catalytic action.
It is considered that not only adsorption but also removal by oxidative decomposition was added, so that the deodorizing performance was further improved.

Met. In this state, no heat is transmitted to the zeolite 5 of the downstream filter 1b, and no high-temperature air is discharged from the discharge port 8. Even if the current is stopped after 5 minutes, the temperature can be maintained by the reaction heat generated by the oxidative decomposition. Therefore, when the air purifying apparatus of this embodiment is continuously operated, the heater 12 may be intermittently energized so as to keep the filter temperature at an appropriate temperature. Thereby, the filter 1
Temperature can be prevented from rising too high, and thereby exhausting hot air. Further, power consumption can be reduced.

1に示した。Next, a description will be given of the results of experiments performed in the first, second and third embodiments of the present invention to confirm whether the reduction of the removal performance can be prevented by the photocatalyst in the air purifying apparatus using only activated carbon. . The three types of air purification devices were placed in a 6 m 3 test box, and the concentration of ammonia in the test box was adjusted to 20 ppm. After the operation of the fan of the blowing means 9 at a flow rate of 3 m 3 / min for 30 minutes, the density in the box was measured (the number of times of light irradiation is 0, which is referred to as an initial value). Thereafter, the fan of the blowing means 9 is stopped, and the black light 10 is energized.
Light irradiation was performed for 2 hours. Again, the ammonia concentration in the box was adjusted to 20 ppm, and the concentration after operation for 30 minutes was measured (this is the first light irradiation). Table 1 shows changes in the concentration of ammonia in the box when these series of operations are repeated five times. In the air purifying apparatus of Example 2, the heater was not energized during the operation for 30 minutes, but was intermittently energized and heated only during light irradiation. Experiments were also conducted using the air purification device of Example 1 when light irradiation was not performed, and

ことが確認された。In the initial state, a filter using only activated carbon is used.
Although the residual ammonia concentration is slightly higher than the others, there is almost no difference in performance between the various air purification devices.
It can be seen that as the operation and regeneration are repeated, the concentration of ammonia remaining in the air purification device using only activated carbon gradually increases, and the removal performance decreases. Similarly, when light irradiation is not performed using the air purification device of the first embodiment, the remaining ammonia concentration increases as the number of times increases, but the increase is slightly slower than that of activated carbon. It can be seen that the air purifiers of Examples 1, 2 and 3 clearly have a smaller increase in ammonia concentration than the two air purifiers, and that the photocatalyst prevents a decrease in removal performance. Particularly, in Examples 2 and 3, there was almost no decrease. In Example 2, heating by the heater 12 was also performed at the time of light irradiation, and manganese oxide and copper oxide, which were the metal oxides 2, were heated and activated, and ammonia was oxidatively decomposed by a catalytic action. This is also considered to be the effect of the improvement in efficiency by heating. In the third embodiment, the photocatalyst 3 is present a lot on the surface of the upstream portion of the filter to which a large amount of ammonia is adsorbed, and OH radicals are generated near the ammonia to be decomposed. Probably because it was done well. From the above results, it was confirmed that the air purification device of the present example prevented the reduction of the removal performance and maintained the initial removal performance.
