Combination of the pre-filter 110, the vortex forming space 120, the UV lamp 132 and the photocatalyst filter 134 sequentially according to the flow of air as the air purification means (110 ~ 140) It consists of a photolysis reaction unit 130, the adsorption removal unit 140 consisting of the activated carbon filter 142, and thus the photocatalyst filter 134 and the activated carbon filter 142 can be seen as the main filter.

The pretreatment filter 110 is provided at the rear of the inlet 104 to adsorb and remove relatively coarse pollutants contained in the contaminated air sucked through the inlet 104, and thus the main filters 134 provided at the rear of the inlet 104. , 142) also serves to protect, it can be made of a non-woven fabric that is commonly used air permeability.

According to the present invention, the pretreatment filter 110 may be used that is coated with zeolite (zeolite) to additionally provide a deodorizing function on the surface of the non-woven fabric, and thus odor odor from the simple filtration function Some deodorization of the material can also be provided.

In addition, according to the present invention, the above-described pretreatment filter 110 is installed to be inclined so that its upper end side is close to the suction port 104 side and its lower end side is remotely separated from the suction port 104.

On the other hand, the vortex forming space 120, which is an empty space, is formed at the rear side of the pretreatment filter 110 described above, and in the vortex forming space 120, contaminated air introduced through the pretreatment filter 110 is vortexed. (T) is formed, and the vortex (T) formation principle is provided with a pretreatment filter (110) inclined to serve as a masking to some extent, and lower relative to the upper side close to the blower (150). In view of the stronger suction force than the side, contaminated air flows into the upper end side of the pretreatment filter 110 at high pressure and high speed, and the lower end side flows into the low pressure and low speed. As described above, the vortex T of the contaminated air in the clockwise direction is formed, and once the vortex T is formed in this way, the contaminated air stays in the vortex forming space 120 for a longer time. After the vortex T is formed, some air is discharged to the upper side from the upper side of the vortex T formed by the suction force of the blower 150 which is continuously operated.

Furthermore, the photolysis reaction unit 130 and the adsorption removal unit 140 are provided on the upper side of the above-described vortex forming space 120, and may be provided as one integrated unit.

The photolysis reaction unit 130 is composed of a combination of the UV lamp 132 and the photocatalyst filter 134, the UV lamp 132 is provided on each side, that is, the upper and lower sides of one photocatalyst filter 134, such The combination of the UV lamp 132 and the photocatalyst filter 134 deodorizes and sterilizes the polluted air that flows in. Hereinafter, the principle of the deodorization and sterilization will be described.

As is well known, the UV lamp 132 can independently provide the action by the UV / O3 Advanced Oxidation Process using a combination of ultraviolet (UV) and ozone (O3) that can be generated by itself, photocatalyst The photocatalyst of the filter 134 is activated by the ultraviolet rays irradiated from the UV lamp 132 to provide the action by photocatalytic oxidation, and thus, deodorization by ozone and the photocatalyst, germicidal ultraviolet ray and ozone It can be provided at the same time sterilization by.

Although the above-mentioned photooxidation method can exhibit very strong oxidizing (deodorizing) and bactericidal (antibacterial) ozone in a very short time, it does not actually react at all with organic substances, so that the reaction is extremely selective. To this end, OH radicals, which are generated through various paths in which ozone is photoly decomposed by ultraviolet energy, use a reaction that greatly increases the oxidation and sterilizing power of ozone and ultraviolet rays. It is produced by irradiating ultraviolet rays of.

In other words, the photo-oxidation method by ultraviolet and ozone can be very effective in removing odors by decomposing organic substances and harmful substances that cause various odors as well as high sterilization effect.

On the other hand, in the photocatalytic oxidation reaction described above, when ultraviolet rays are irradiated to the photocatalyst, radicals (OH) and free radicals (O2-) are generated, and organic and harmful substances are decomposed by their high oxidation and reduction reactivity. Say

Accordingly, the UV lamp 132 is provided with various wavelengths such as ozone generation wavelength and germicidal wavelength, so as to generate ultraviolet rays having self sterilization power together with ultraviolet rays capable of smoothly causing photoacidification and photocatalytic oxidation reaction as described above. Irradiated multi-wavelength UV lamps are used, or UV-A lamps with a wavelength band of 315-400 nm that have good wavelength absorption for photocatalysts and UV-B lamps with a wavelength band of 280-315 nm that have good self-sterilization effect It can be installed and used in parallel.

At this time, the UV lamp 132 by the UV lamp 132-1 provided on the lower side of the photocatalyst filter 134, that is, the upper side of the vortex forming space portion 120 in deodorizing and sterilizing the contaminated air. In order to maximize the deodorizing and sterilizing effect, in the present invention, as described above, the vortex (T) of the contaminated air is formed in the vortex forming space 120 so that the contaminated air is delayed, thereby sufficiently deodorizing and sterilizing during the delayed stay. It is to be done.

In addition, the photocatalyst filter 134 may be used that is coated with a photocatalyst on the base of the non-woven fabric having good air permeability, and close to the UV lamp 132 to some extent in order to maximize the efficiency of the combined action with the UV lamp 132. It should be installed as possible, and a plurality can be provided to improve the deodorizing and sterilizing effect, and each of the UV lamps 132 on the upper and lower sides of the photocatalyst filter 134 is ultraviolet to both sides of the photocatalyst filter 134. To investigate.

Next, at least one activated carbon filter 142 is provided on the upper side of the photolysis reaction unit 130 of the combination of the UV lamp 132 and the photocatalyst filter 134 described above, and the activated carbon filter 142 is a honeycomb. Pellet-type activated carbon filled in a plurality of pellets in the shape of the filter can be used, so that the pollutants contained in the polluted air is adsorbed during the passage of the polluted air through the porous activated carbon In other words, after most of the contaminants are removed from the vortex forming space 120 and the photolysis reaction unit 130, only the contaminants remaining without being completely removed from the adsorption removing unit 140 are completely removed. It will be removed.

At this time, the activated carbon used may be to improve the selective adsorption performance for a particular contaminant by the surface is chemically modified or impregnated with a chemical.

Thus, according to the present invention, overall, dust and deodorization by the zeolite-coated pretreatment filter 110, sufficient deodorization and sterilization by ultraviolet irradiation in the vortex forming space 120, in the photolysis reaction unit 130 The deodorization of the adsorption and removal unit 140 by the combined action of the deodorization by the activated carbon filter 142 will be able to effectively and completely harmless contaminated air containing a large amount of contaminants, especially odors and harmful bacteria.

According to the present invention, the adsorption capacity is provided to be close before the adsorption capacity is saturated. The contaminants attached to the filters 134 and 142 are also gradually decomposed by the action of ultraviolet rays irradiated from the UV lamp 132, which can be regenerated to some extent by itself. It can be used longer.

In addition, since the ozone is generated as described above by using the UV lamp 132 in the photolysis reaction unit 130, the ozone is contained in the air after ozone treatment and may be harmful to the human body by leaking to the outside. According to the present invention, the corresponding air containing ozone is completely filtered in the next activated carbon filter 142, so that the contained ozone can be adsorbed and removed, thereby preventing problems caused by the ozone outflow as described above.

In addition, in order to further improve the sterilization (antibacterial) effect, the surface of the paper filter constituting the above-described activated carbon filter 142 may be coated with silver nano (Ag) which may provide a sterilization function on its own. .

Next, the contaminated air passing through the pretreatment filter 110 is introduced into the vortex forming space 120 at the rear side thereof, and the contaminated air is introduced into the inclined pretreatment filter 110 and the relative suction force difference between the upper and lower sides. By forming the vortex T by this, it does not immediately exit from the vortex forming space 120, but is delayed to some extent in the space.

In this way, the contaminated air that is delayed and stayed is sufficiently irradiated with ultraviolet rays from the UV lamp 132-1 of the upper side, and deodorization and sterilization of the contaminants contained therein are performed by the photooxidation reaction by the corresponding ultraviolet rays.

At this time, since the suction force from the blower 150 provided on the upper side is continuously operated, some air from the upper side of the formed vortex T continues to escape to the upper side, and the contaminated air moved to the upper side is UV Into the photolysis reaction unit 130 consisting of a lamp 132 and a photocatalyst filter 134 is deodorized to the contaminants contained by the photocatalytic oxidation reaction in the corresponding section.

Next, the contaminated air that is continuously moved to the upper side through the photolysis reaction unit 130 flows into the adsorption removal unit 140 made of the activated carbon filter 142 and passes through the corresponding activated carbon filter 142 while remaining contaminated therein. The material is adsorbed and removed.

Then, the clean air completely harmless by passing through the adsorption removal unit 140 passes through the intake duct 152, the blower 150, the drawout duct 154, the discharge port 106, and is finally discharged to the outside, At this time, the functionality is added to the clean air discharged by the action of the functional unit installed on the blower 150 side or the discharge port 106 side.

As a result, the above-described action is continuously performed to continuously purify a large amount of contaminated air, and summarizing the purification action, dust collecting, deodorization and vortex formation by the zeolite-coated pretreatment filter 110 Contaminated air containing high concentrations of odor and harmful bacteria by the combined action of sufficient deodorization and sterilization by ultraviolet irradiation in the space 120, deodorization by the photocatalyst filter 134, deodorization by the activated carbon filter 142 It will be stable and completely harmless.

As described above, the above description merely illustrates a preferred embodiment of the present invention, and those skilled in the art should recognize that modifications and changes can be made to the present invention without changing the subject matter of the present invention.

According to the present invention, it is possible to completely purify the polluted air containing a high concentration of odor and harmful bacteria with high efficiency, can be useful in the workplace where a large amount of odor and harmful bacteria are generated, providing a comfortable environment, Self-regeneration of filters and adsorbents is also possible, providing convenience by prolonging the replacement cycle, and having a simple configuration without generating secondary pollutants, thus making it possible to operate very economically.
