Description

Three-dimensional photocatalyst filter module and air purifier using the same}

The present invention relates to a three-dimensional photocatalyst filter module including a photocatalyst filter that secures a sufficient surface area, facilitates ultraviolet irradiation, and improves contact efficiency by inducing turbulence, and an air purifier to which the same is applied.

Air purifiers that utilize the phenomenon in which harmful gases in contact with the photocatalyst are decomposed and purified when ultraviolet rays are irradiated to the photocatalyst are becoming popular.

These air purifiers mainly use ultraviolet LEDs (UV-LEDs) as a light source and are structured to irradiate the ultraviolet rays to a filter containing or coated with a photocatalyst material.

Air purification using photocatalysts is achieved by the principle that harmful gases are decomposed when they come into contact with a photocatalyst irradiated with ultraviolet rays.

In an air purifier based on this principle, ultraviolet rays must be evenly radiated to all surfaces of the photocatalyst filter to increase air purification ability. In addition, in such air purifiers, the surface area of the photocatalyst filter must be large to increase the area that harmful gases can contact, thereby increasing the air purification ability.

However, if the filter is manufactured into a complex shape to expand the surface area of the filter, there is a problem that the area where ultraviolet rays cannot be irradiated increases. Conversely, if the shape of the filter is simplified to reduce the shaded area, there is a problem in that the surface area of the filter cannot be expanded that much.

Additionally, photocatalytic filters with complex shapes have the problem of poor scalability. For example, in the past, even if a photocatalyst filter was designed to increase the surface area of the filter and not generate an ultraviolet shadow area, there was the inconvenience of requiring a new design to change the shape of the photocatalyst filter every time the purification capacity was increased or changed.

The present invention was developed to solve the above-mentioned problems, and includes a photocatalyst filter module that has a simple shape, can secure a sufficient surface area, and has a shape that allows ultraviolet rays to be evenly irradiated to all surfaces, and the air to which the same is applied. We would like to provide a purifier.

The present invention seeks to provide a photocatalytic filter module having a photocatalytic filter of a shape that induces turbulence and has excellent contact efficiency with air, and an air purifier to which the same is applied.

In order to increase the contact efficiency between air and the photocatalyst filter by inducing turbulence in the air flow while preventing the occurrence of shaded areas that are not exposed to ultraviolet rays on the surface of the photocatalyst filter without compromising the scalability of the purification capacity of the photocatalyst filter module. The photocatalyst filter may have a three-dimensional shape.

Referring to Figures 1 and 2, the photocatalyst filter module 10 may be provided with a plurality of photocatalyst filters 11 spaced apart along the longitudinal direction. The photocatalytic filter 11 may be in the shape of a plate having a rectangular outline with a predetermined width and a predetermined height. The outline of the photocatalytic filter 11 may have a width and height of several centimeters to tens of centimeters. The photocatalyst filter 11 provided in the photocatalyst filter module 10 of the first embodiment is illustrated as having a flat plate shape.

The photocatalyst filter 11 may have a structure in which a photocatalyst material is coated on a mesh-shaped base.

The photocatalyst filter 11 may have a structure in which a photocatalyst material is sintered without a base.

The photocatalyst filter 11 may be made of a porous material that allows air to pass through its thickness. The thickness of the photocatalyst filter 11 may be as thin as 1 mm or less and may have fine holes of 1 mm or less. In the embodiment shown in the drawing, only a portion of the porous portion penetrating in the longitudinal direction is shown for convenience, but it will be understood that the porous portion is provided over the entire area.

The width and height of the photocatalytic filter 11 may be, for example, 15 cm and 15 cm.

For example, five photocatalyst filters 11 may be prepared.

Each of the plurality of photocatalytic filters 11 may be arranged substantially perpendicular to the longitudinal direction or the front-to-back direction and may be spaced apart from the front-to-back direction. The distance between two photocatalyst filters 11 neighboring in the front-back direction may be, for example, 5 to 10 cm.

The size and number of photocatalyst filters 11 can be changed as needed.

The plurality of photocatalyst filters 11 may be connected to each other by a connection frame 12 extending in the longitudinal direction to connect each photocatalyst filter in the front and rear directions to form a photocatalyst filter module 10.

The connection frame 12 may include a corner frame 123 extending in the longitudinal direction to connect the corner portions of the width direction end and the height direction end of each photocatalyst filter.

The connection frame 12 may include a middle frame 125 extending in the longitudinal direction to connect the central portion of the height direction end of each photocatalyst filter.

The corner frame 123 and the middle frame 125 are manufactured to be as thin as possible to maintain rigidity, thereby reducing the space occupied by the photocatalyst filter module 10 and preventing them from affecting the flow of air for the photocatalytic reaction. You can.

The photocatalytic filter module 10 may have an overall or substantially rectangular parallelepiped outline.

You can. Additionally, additional photocatalyst filters 11 can be easily installed, providing excellent expandability.

3 to 6, a light source module 40 may be installed or assembled in the photocatalyst filter module 10.

The light source module 40 includes a plurality of light sources 42.

The plurality of light sources 42 may be installed on the base substrate 41.

The base substrate 41 is disposed at the lower end of the photocatalytic filter module 10 and covers the lower end of the photocatalytic filter module 10. In this state, the light source 42 is disposed between the photocatalyst filters 11 in the front-back direction and can irradiate ultraviolet rays forward and backward toward the photocatalyst filter 11.

The shape of the photocatalytic filter 11 is maintained constant along the vertical direction. The photocatalyst filter 11 provided in the photocatalyst filter module 10 of the first embodiment has a width direction extension portion 111 extending in the width direction across the entire width direction. The cross-sectional shape of the photocatalyst filter 11 defined by a plane including the width direction and the longitudinal direction is maintained constant along the vertical direction.

The light source 42 has a shape extending in the vertical direction. In addition, the light source 42 may irradiate ultraviolet rays in a direction crossing the up and down directions, such as the width direction or the front and rear direction.

The light source 42 is disposed ahead of the photocatalyst filter module 10 and can radiate ultraviolet rays backward toward the photocatalyst filter 11.

The light source 42 is disposed rearward than the photocatalyst filter module 10 and can irradiate ultraviolet rays forward toward the photocatalyst filter 11.

The light source module 40 of the first embodiment is illustrated in that the base substrate 41 is provided on the bottom, and the light source 42 extends upward from it. However, the light source module 40 in which the base substrate 41 is provided on the ceiling and the light source 42 extends downward from it is also applicable. In addition, of course, it is possible to configure the light source module 40 to which both types are applied.

The light source 42 may include an ultraviolet LED (421). The ultraviolet rays emitted from the ultraviolet LED 421 have the characteristic of focusing their intensity at the peak wavelength, unlike conventional ultraviolet rays that generate ultraviolet rays of a wide spectrum.

As shown in Figure 33, BaP has the best decomposition ability when irradiated with ultraviolet rays with a peak wavelength of 254 nm, and PYRE has the best decomposition ability when irradiated with ultraviolet rays with a peak wavelength of 310 nm. In other words, when ultraviolet rays with different peak wavelengths are irradiated to the photocatalyst filter, it can be seen that there is a difference in decomposition ability depending on the type of gas to be decomposed.

According to an embodiment, photodecomposition efficiency can be increased through the light source 42 including an ultraviolet LED 421 having a peak wavelength particularly suitable for decomposition of the binding site of a specific gas to be decomposed.

Each of the plurality of light sources 42 may be manufactured to irradiate ultraviolet rays having a specific peak wavelength.

For example, the first light source 42-1 may be manufactured to include only one or two ultraviolet LEDs 421 having a first peak wavelength.

For example, the second light source 42-2 may be manufactured to include only the ultraviolet LED 421 having a second peak wavelength different from the first peak wavelength.

For example, the third light source 42-3 may be manufactured to include only the ultraviolet LED 421 having a third peak wavelength different from the first and second peak wavelengths.

The N-th light source 42-N may be manufactured to include only the ultraviolet LED 421 having an N-th peak wavelength different from the 1st to N-1th peak wavelengths. Here, N may be a natural number of 4 or more.

The first peak wavelength to the Nth peak wavelength may be selected from 300 nm to 450 nm, respectively. For example, these peak wavelengths may be 325 nm, 345 nm, 365 nm, 385 nm, or 405 nm.

For example, the light source module 40 including a plurality of light sources 42 may include one or more first light sources 42-1 and one or more second light sources 42-2. For example, the plurality of light sources 42 may additionally include one or more third light sources 42-3. For example, the plurality of light sources 42 may additionally include one or more Nth light sources 42-N.

If the same type of ultraviolet LEDs 421 are mounted on one substrate, it is more advantageous to control the ultraviolet LEDs 421. In addition, if one light source 42 is composed of ultraviolet LEDs 421 having the same peak wavelength, the light source module 40 can be configured by combining light sources 42 with different peak wavelengths, so that the light source module 40 is optimally suited to the usage environment. It is easier to manufacture the light source module 40.

Referring to the assembly structure of the photocatalytic filter module 10 of the first embodiment and the light source module 40 of the first embodiment shown in FIGS. 3 to 6, as shown, the light source module 40 includes a plurality of light sources ( 42) may be arranged to be spaced apart along the width direction between two photocatalyst filters 11 adjacent in the longitudinal direction. The light source 42 may be installed in a form that minimizes interference with the flow of air flowing along the longitudinal direction.

Referring to FIG. 6, in the light source module 40, the peak wavelengths of two light sources 42 adjacent in the width direction are different from each other.

And in the light source module 40, among the light sources 42 adjacent in the longitudinal direction with one photocatalyst filter 11 in between, each is provided in front and behind the photocatalyst filter 11, but has a width. The peak wavelengths of the two light sources 42 arranged closest in direction are different from each other.

Light sources installed in these different shapes can evenly distribute ultraviolet rays of different peak wavelengths.

Additionally, the light sources arranged in a row in the direction of air flow, that is, the front-to-back direction, may include light sources of all peak wavelengths installed in the light source module 40. Accordingly, the air flowing along the flow direction within the housing 30 can be exposed to light sources of all types of peak wavelengths installed there. As a result, the air flowing inside the housing 30 can be decomposed in contact with the photocatalyst filter 11, which is irradiated with ultraviolet rays of all peak wavelengths intended for design.

Referring to FIGS. 7 to 9 , the assembly of the photocatalyst filter module 10 and the light source module 40 may be accommodated inside the housing 30.

The front and back sides of the photocatalyst filter module 10 may face the intake face plate 34 and the exhaust face plate 35 in the front and rear directions, respectively. An intake fan 342 may be installed in the intake port 341, and an exhaust fan 352 may be installed in the exhaust port 351. The front of the photocatalyst filter module 10 and the intake surface plate 34 may be arranged at a predetermined interval, for example, about 5 cm.

The size of the intake port 341 and the exhaust port 351 may be, for example, several centimeters to several tens of centimeters in diameter.

In the air purifier, air flows into the housing from the front through the intake port 341 of the housing 30, air flows rearward through the space where the photocatalyst filter module 10 is installed, and the exhaust port 351 Air can be discharged from the inside to the rear.

The air may be air in the atmosphere of general living areas, air in a special environment such as a factory, or mixed gas. The air purifier can be used, for example, for domestic purposes, or can be installed, for example, in air conditioning equipment in a building or factory.

An intake filter 343 may be provided in front of the photocatalyst filter 11 to block foreign substances from entering the housing 30. The intake filter 343 may be provided in front of the intake fan 342. In the embodiment shown in the drawing, ventilation holes are shown in a portion of the intake filter 343 for convenience, but it will be understood that the ventilation holes are provided over the entire area.

A control board for controlling the air purifier may be installed below the intake port 341 on the inner surface of the intake surface plate 34.

The control board may be provided between the lower surface of the photocatalyst filter module 10 and the base plate 31. For this purpose, a space of several cm may be provided between the photocatalyst filter module 10 and the base plate 31. In this structure, the base substrate 41 of the light source module 40 can block the lower part of the photocatalyst filter module 10.

The size and capacity of the photocatalyst filter module 10 can be flexibly and easily changed to suit the installation environment by adjusting the size of the photocatalyst filter 11, the number of photocatalyst filters 11, and the distance between the photocatalyst filters 11. You can. Additionally, additional photocatalyst filters 11 can be easily installed, providing excellent expandability.

The photocatalyst filter module 10 may be supported by a pair of side supports 20 respectively disposed between both sides of the photocatalyst filter module 10 and the pair of side plates 32.

The side support 20 may include a side blocking plate 21 extending in the front-back direction to block the sides of the space between two photocatalyst filters 11 arranged adjacent to each other in the longitudinal direction. Accordingly, the air flowing backward through the photocatalyst filter module 10 necessarily flows backward through a plurality of photocatalyst filters 11, as shown in FIG. 9. That is, the side blocking plate 21 can prevent the air from bypassing to another path instead of passing through the photocatalyst filter 11.

The side support 20 may further include a front blocking plate 22 extending laterally from the front end of the side blocking plate 21 and connected to the side plate 32. The front blocking plate 22 can block the space between the side blocking plate 21 and the side plate 32 from the space in front of the photocatalytic filter 11 disposed at the front.

Accordingly, the front blocking plate 22 ensures that all air flowing into the space between the intake surface plate 34 and the front of the photocatalyst filter module 10 through the intake port 341 is transferred to the photocatalyst filter module 10. Guide it to flow inside.

In order to increase photocatalytic reaction efficiency, a side additional plate 25 may be interposed between the side blocking plate 21 and the photocatalytic filter 11.
