とする。In the case of an air purifying apparatus having a filter medium in which the photocatalytic filter and the antibacterial filter are laminated in the air circulation passage, the sterilizing effect is increased when the sterilizing effect is increased. Due to their size, silver-based antibacterial agents are used as antibacterial agents, but they become silver halide in an environment where chlorine-based substances are present and under light irradiation, and the antibacterial properties are lost, resulting in a short life. In addition to the above, it also has a problem of safety for human body and environment. Furthermore, the problem that the antibacterial agent is detached or peeled off from the filter medium and causes secondary pollution is pointed out, and the use in the fields requiring high safety such as food, pharmaceuticals, and medical care is restricted. have. Further, in the case of an air conditioner in which an ultraviolet lamp is provided between the photocatalytic filter and the medium performance filter, only the photocatalytic reaction due to the combination of the ultraviolet lamp and the photocatalyst affects the sterilization effect of the entire device, so There was an inconvenience that the bacterial effect itself was low from the beginning. Therefore, an object of the present invention is to provide an air cleaning device that can maintain an excellent sterilization effect for a long period of time.

However, any increase in pressure loss can be suppressed, and there is no ultraviolet ray leakage, so that various types of gaseous pollution can be obtained. From the viewpoint of safe decomposition of the substance, it is preferable to use a breathable sheet obtained by immobilizing a photocatalyst on a network base material having an opening ratio of 10 to 50%. If the opening ratio is less than 10%, the light transmittance may be lowered, the air permeability may be deteriorated, and the pressure loss may be increased. If the opening ratio exceeds 50%, the effect of the photocatalyst may be reduced. In addition, ultraviolet rays leak to the outside, which poses a safety issue. Further, since the photocatalyst itself can be easily regenerated by heating, it is preferable to use a heat resistant substrate. Further, from the viewpoint of the adsorption function of gaseous pollutants, it is preferable to use a substrate whose surface is made porous by acid treatment or the like.

Such an ultraviolet lamp is preferable because it can increase the effective irradiation light amount to the photocatalyst, the photocatalytic action becomes strong, and it is ozoneless. In particular, in the biological field such as food, medicine and medical treatment, the combined use of an ultraviolet lamp and a photocatalyst is preferable because of its high bactericidal effect. Furthermore, in a clean room, it is possible to remove bacteria and microorganisms.

塵濾過材が使用される。As the enzyme-carrying filter material, for example, various dust-removing filter materials on which an enzyme having a bactericidal effect such as a lytic enzyme is carried are used. Not only does the lytic enzyme have a broad sterilization spectrum and strong bactericidal activity, but it is also chemically immobilized uniformly on the entire filter material, and the enzymes are chemically bonded at the molecular level. It is preferable to use it because it is free from desorption and peeling and secondary contamination does not easily occur. Further, as the dust removing filter medium carrying the enzyme, any dust removing filter medium such as ULPA filter medium, HEPA filter medium, medium performance filter medium and coarse dust filter medium is used depending on the desired cleanliness. .
