も採用しえるのは勿論である。The fans 11 and 12 can be provided either upstream or downstream of the path, but if the fan 11 is provided on the downstream side of the air cleaning path 15 of the air cleaning apparatus 1, it becomes a suction type. Compared to the pressurization type in which ozone gas is pushed in,
There is no leakage to the outside. In addition, if a fan 12 is provided in the ozone fumigation path 16, a push-in type is used, but in this case, it is possible to carry out a treatment so that ozone is not destroyed, as will be described later. Although a centrifugal fan is shown in FIG. 1, it is needless to say that a lateral flow fan or a sirocco fan can also be used.

ある。The fan 12 which is a blowing means in the ozone fumigation path 16 can be arbitrarily changed in rotation speed by inverter control. During ozone fumigation, the rotation speed of the fan 12 can be changed arbitrarily to change the environment. The ozone generation amount can be adjusted in an optimum operating condition depending on the conditions, for example, the size of the room, temperature and humidity. That is, the fan 12
This is because the amount of ozone decomposition can be adjusted by the number of revolutions, and if it is provided on the downstream side, ozone that is actually generated will be adsorbed by the fan and ozone decomposed by the rotating action, which will affect the ozone generation efficiency. Here, the term "during ozone fumigation" refers to a case where the ozone concentration is high and sterilization and deodorization are performed directly indoors when there is no person.

合である。When ozone is deodorized in the air purifying path 15, the rotation speed of the fan 11 is increased to increase the wind speed and the air volume, and the ozone decomposition amount is increased to supply harmless air. It is also possible. Here, when ozone is deodorized, sterilization is performed in the air purifying apparatus 1. However, ozone is decomposed by an ozone decomposing catalyst in the apparatus 1, and deodorization is performed by the deodorizing action at this time. When to do.

For sterilization, an ozone generator with an ozone generation rate of several hundred to several thousand mg / h is used.
By using an ozone generator of about h, ozone can be effectively used, safety is ensured during deodorization, and the life of the ozone decomposition catalyst can be extended. It is also possible to adjust the ozone generation amount by adjusting the output of the ozone generator.

を分解する。An electrostatic precipitator 9 or a photocatalyst 10 can be provided downstream of the ozone decomposition catalyst 8. When the electric dust collector 9 is used, it electrically decomposes the residual ozone odor. Further, at this time, negative ions are obtained, and it is possible to supply air in an environment favorable to the human body. When a photocatalyst is used, the residual ozone odor is decomposed by the redox action.

着作用の為寿命の問題がある。Since ozone has a low reactivity to, for example, ammonia, it may be possible to place an activated carbon filter on the downstream side of the ozone decomposition catalyst. However, activated carbon cannot adsorb a substance having a small molecular weight and deodorizes. The function has a life problem mainly due to the adsorption action.

Become. The deodorizing function has a long life, mainly due to the redox action, and also has a deodorizing and bactericidal action. In addition, activated carbon itself does not have a bactericidal effect, so that it easily becomes a hotbed for bacteria, but photocatalyst does not have such a phenomenon.

It can be carried out. An ozone generator power supply 60 is provided for that purpose. In this case, the shape can be further reduced, which results in compactness and downsizing. It is also possible to change the ozone generation amount to some extent by adjusting the voltage.

When the ozone generator 6 is installed in the ozone fumigation path 16, it is possible to install it along the flow path with a sufficient margin even if the shape is long, even if the capacity is increased. Become.

When the irradiation is carried out by this, the airborne bacteria contained in the untreated air, here, the thermal energy of the ultraviolet lamp 3 damages the DNA of the bacterium, and as a result, the self-propagating function is formed by the formation of the chimming dimer. Lower.

気と接触しても反応が起こる。For airborne bacteria contained in untreated air, a combination of ultraviolet rays of a specific wavelength and a photocatalyst is effective. That is, the characteristic feature of the titanium oxide photocatalyst system is that the reaction occurs when its surface comes into contact with water. Due to its adsorptivity, if it is not completely dry, a reaction will occur even if it comes into contact with air.

ある。For the titanium oxide photocatalyst, preferably UV radiation in the wavelength range 315-400 nm is suitable for exciting the photocatalyst. When the ultraviolet lamp 4 having a wavelength of about 400 nm hits the surface of titanium oxide, a strong oxidation potential of 3 V is generated, water is decomposed and active oxygen is generated. This has a larger oxidation potential than chlorine, hydrogen peroxide, ozone, etc., and can decompose and oxidize almost everything.

The titanium oxide photocatalyst (anatase type) photocatalytic filter 5 is further activated, active oxygen is generated, and bacterial spores and verotoxin are destroyed.

ことが出来る。On the other hand, the ultraviolet lamp 3 without a photocatalyst in the preceding stage may be a normal germicidal lamp having a wavelength of 100 to 280 nm. This is because the photocatalyst has an effect of causing the action, but it is low. In this way, if the normal UV irradiation is performed in the previous stage and the photocatalyst is irradiated by changing the wavelength of the UV, the bactericidal effect can be further enhanced.

殺菌効果が減じるからである。When the irradiation of ultraviolet rays in the previous stage is reversed,
This is because the active oxygen changes the surface layer of the spores and a part of the DNA inside, and the generation of TDHT in the spores is suppressed during UV irradiation, and the bactericidal effect is reduced because some bacteria cannot be completely sterilized.

That is, ozone gas can be filled and sterilized even outside the range where ultraviolet rays cannot reach, and when ultraviolet rays or a photocatalyst is used, ozone gas easily damages the spores of cells and further sterilization effect is obtained.

を可能にする。Bacteria that have come into contact with the antibacterial agent die by causing metal cations (eg, silver, zinc, copper ions, etc.) to destroy the protein and cause a bacteriolysis phenomenon. The air purifying device 1 mainly has a function of sterilizing and deodorizing falling adherent bacteria. The above configuration enables systematic sterilization and deodorization.

The sterilization time can be shortened and the cost can be reduced.

オゾン分解触媒装置の作動は、同様に行われる。After this, the operation of the air cleaning fan 11 of the air cleaning device 1 is restarted again. The untreated residual ozone air is sucked into the ozone decomposition catalyst device 8. In this way, the air inside the chamber circulates and the ozone is decomposed by the action of the ozone decomposition catalyst device 8. Hereinafter, the operation of the ozone decomposition catalyst device after sterilization and deodorization is similarly performed.
