Description

Photocatalyst media module for air purifier {Photocatalyst media module for air purifier}

The present invention relates to a photocatalyst media module for an air purifier. More specifically, it relates to a photocatalyst media module for an air purifier that can effectively sterilize air using ozone and hydroxyl radicals generated in reaction with ultraviolet rays.

Typically, air purification devices purify polluted air generated in homes, offices, industrial sites, etc., and include a purifier body with an air inlet and an air outlet, and air that is stacked in multiple layers within the purifier body and filters the air flowing in through the air inlet. It consists of a filter and an air fan built into the purifier body that causes air flow so that external air flows into the purifier body and then the air filtered by the air filter is discharged into the room through the air outlet.

These air purification devices rely on air filters to purify the air, but no matter how high-performing air filters are used, there are limits to air purification. In other words, fine harmful substances pass through the filter, and bacteria multiply in the air filter and contaminate the purified air.

Accordingly, in the previously disclosed patent publication No. 10-2019-0024390, a base with a blowing fan installed on the inside and configured to suck air from an inlet hole formed in the center of the upper side and discharge it through an outlet formed along the lower side; An ultraviolet ray generator consisting of a support formed vertically above the inlet hole and a light-emitting module installed outside the support to emit ultraviolet rays of a set wavelength; A first flow part is formed on the inside and surrounds the ultraviolet ray generator, and a plurality of through holes are formed so that air from the outside flows inward and flows into the inlet hole, and reacts with the ceramic coating layer and ultraviolet rays to generate ozone and hydroxyl radicals. A primary filter unit with a photocatalyst coating layer formed thereon; a secondary filter unit that forms a second flow unit inwardly and surrounds the primary filter unit, removing foreign substances in the air passing from the outside to the inside; A cylindrical case forming a third flow part inside and surrounding the secondary filter part; A technology consisting of a cover that covers the case from the upper side and has an intake port for sucking air to the upper side and flowing it into the third flow section has been previously proposed.

In addition, in another prior art, Registered Utility No. 20-0494084, a housing having an air intake port formed on one end and an air discharge port formed on the other side; A suction fan installed inside the housing, sucking air through the air intake port and discharging it through the air outlet; a circuit board having a plurality of first air flow ports through which air passing through the air intake port flows; Photocatalyst particles, which are titanium dioxide particles that decompose organic compounds by receiving ultraviolet rays, are applied to the surface of the plate interposed between the circuit board and the suction fan and facing the circuit board by chemical vapor deposition. A photocatalyst plate having a plurality of second air flow ports through which air flows; A filter member inserted into the filter insertion groove formed on the front of the housing and removing particulate matter from the air sucked into the housing; and mounted on the circuit board facing the photocatalyst plate, irradiating ultraviolet rays to the photocatalyst particles. A technology including multiple UV LED devices has been previously registered.

However, the above prior technologies are intended to improve the air purification ability using a photocatalyst filter, but since the air sterilization capacity is proportional to the size of the primary filter part (photocatalyst plate) on which the photocatalyst coating layer is formed, there is a limit to increasing the sterilization capacity in a compact structure. Due to the structural characteristics of air being output through the primary filter unit (photocatalyst plate) on which the photocatalyst coating layer is formed, there was a problem that the sterilization efficiency by the photocatalyst was greatly reduced.

This is a flat configuration diagram.

The present invention is intended to provide a photocatalyst media module that can effectively sterilize air using ozone and hydroxyl radicals generated by reacting with ultraviolet rays. As shown, it largely includes a photocatalyst drum 10, a photocatalyst pin 20, It consists of a main component including an ultraviolet lamp (30) and a first filter member (40).

First, the photocatalyst drum 10 according to the present invention has a photocatalyst chamber 12 coated with a photocatalyst layer on the inside, and a plurality of air passages 14 for introducing air into the photocatalyst chamber 12 are provided on the outer peripheral surface. , a discharge passage 16 is formed within the photocatalyst chamber 12 to discharge sterilized and purified air.

As an example, the photocatalyst drum 10 is formed in a cylindrical shape with the top and bottom open, the lower opening is closed by a base plate, and the upper opening is formed with a discharge passage 16 through which sterilized air is exhausted. do.

In addition, the air passage 14 is arranged at equal intervals on the outer peripheral surface of the photocatalyst drum 10 and is spaced apart in multiple layers, and is formed in a long hole shape extending in the circumferential direction of the photocatalyst drum 10, forming a first filter member 40 to be described later. ) is provided to introduce the filtered air into the photocatalyst chamber 12.

The photocatalyst pins 20 according to the present invention are arranged vertically and spaced apart inside the photocatalyst chamber 12 of the photocatalyst drum 10, and a photocatalyst layer is coated on the outer surface.

The photocatalyst pin 20 has one end connected to the inner peripheral surface of the photocatalyst drum 10, and the other end extends toward the center of the photocatalyst chamber 12 and is radially disposed.

At this time, the photocatalyst pin 20 is manufactured separately from the photocatalyst drum 10 and connected by fixing means including welding or rivets, or is formed into a C or U shape on the outer surface of the photocatalyst drum 10 as shown in FIG. 2. The photocatalyst pin 20 can be formed integrally at the end of the air passage 14 by forming a cut line in the same open curved shape and then bending it inward.

In addition, the photocatalyst pin 20 is coated with a photocatalyst layer like the photocatalyst drum 10, and is equipped to generate ozone and hydroxyl radicals by reacting with ultraviolet rays output from the ultraviolet ray lamp 30, which will be described later.

As the photocatalyst pins 20 formed at the ends of each air passage 14 are radially spaced apart within the photocatalyst chamber 12, air flows into the photocatalyst drum 10 through the air passage 14. is provided to naturally contact the photocatalyst pin 20 to effectively sterilize and purify the incoming air.

Meanwhile, the photocatalyst fin 20 is arranged radially toward the center of the photocatalyst drum 10 as shown in FIG. 3, and its shape may be formed to have a wave-shaped bending line 21.

In the case of the above configuration, the contact area between the photocatalyst pin 20 and the air is expanded due to the wave-shaped bending line 21, thereby improving the efficiency of generating ozone and hydroxyl radicals, and improving the efficiency of air sterilization and purification by ozone and hydroxyl radicals. .

In addition, the photocatalyst pin 20 has its own elasticity because its thickness is thin compared to the length protruding inward.

Accordingly, the photocatalyst pin 20 is provided to vibrate by colliding with and rubbing against the blowing airflow moving through the photocatalyst chamber 12 by the mountain-shaped protrusion formed by the wave-shaped bending line 21.

In this way, since the wave-shaped bending line 21 generates vibration of a very short period inside the photocatalyst chamber 12, the frequency and area in which the photocatalyst pin 20 is in contact with the air per unit time are expanded, and the air is exposed to ozone and hydroxyl radicals. There is an advantage that sterilization and purification efficiency is improved.

The ultraviolet lamp 30 according to the present invention is installed inside the photocatalyst chamber 12 to output ultraviolet rays, and reacts with the photocatalyst layer coated on the photocatalyst chamber 12 and the photocatalyst pin 20 to generate ozone and hydroxyl radicals. It is equipped to do so.

The ultraviolet lamp 30 can be flashed by a separate external power source, or can be used portablely in the absence of a constant power source by placing a battery inside a case installed to surround the photocatalyst drum 10.

Figures 4 to 6 are configuration diagrams showing another embodiment of the photocatalyst media module provided by the present invention, and Figure 7 is a configuration diagram showing an ultraviolet lamp installation structure according to another embodiment.

The ultraviolet lamp 30 is installed at the bottom of the photocatalyst chamber 12 as shown in FIG. 1 to output ultraviolet rays upward, or as shown in FIG. 4, the ultraviolet lamp 30 is installed at the center of the photocatalyst chamber 12. It is supported on the bar 31 and is provided to output ultraviolet rays from the center of the photocatalyst chamber 12 toward the inner peripheral surface of the photocatalyst drum 10.

In addition, ultraviolet rays output from the ultraviolet lamp 30 react with the photocatalyst layer coated on the photocatalyst chamber 12 and the photocatalyst pin 20 to generate ozone and hydroxyl radicals.

The first filter member 40 according to the present invention is installed to surround the outer peripheral surface of the photocatalyst drum 10 to filter external air.

The first filter member 40 is formed in the same shape as the outer peripheral surface of the photocatalyst drum 10 to filter the outside air to prevent dust or foreign substances contained in the outside air from entering before sterilization of the air by the photocatalyst, and filters the outside air in a 360° direction. can be filtered.

The photocatalyst media module 100 of the present invention, configured as described above, forms an open curved cut line on the outer surface of the photocatalyst drum 10 and integrates the air passage 14 and the photocatalyst pin 20 by bending it inward. By forming a structure, structural simplification is achieved to reduce production costs and improve productivity, and the air filtered by the first filter member 40 flows in through the air passage 14 and is provided to contact the photocatalyst pin 20. It has the advantage of providing improved sterilization and purification effects.

Below, the detailed configuration of the air purifier using the photocatalyst media module described above will be described with drawings.

Figure 8 is an exploded configuration diagram showing an air purifier using the photocatalyst media module provided by the present invention. As shown, the air purifier using the photocatalyst media according to the present invention largely consists of a photocatalyst media module 100 and a blowing nozzle 200. ), a blower fan 300, and a second filter member 400. For detailed configuration of the photocatalyst media module 100 according to the present invention, refer to the description of FIGS. 1 to 7 above.

The blowing nozzle 200 according to the present invention is connected to intersect the discharge passage 16 of the photocatalyst media module 100, and has an intake port 210 and an open discharge port 220 at both ends.

The blowing nozzle 200 is formed in a hollow cylindrical shape, and is connected to the middle region so as to communicate with the discharge passage 16 of the photocatalyst media module 100.

That is, the blowing nozzle 200 is connected to the top of the photocatalyst media module 100 in a 'T'-shaped structure, and outputs sterilized and purified air in the horizontal direction while being supported by the photocatalyst media module 100. It is provided.

The blowing fan 300 according to the present invention is installed inside the blowing nozzle 200, and sucks air through the discharge passage 16 of the photocatalyst media module 100 and the intake port 210 of the blowing nozzle 200. It is provided to output to the discharge port 220.

At this time, the blowing fan 300 includes a pair of forward and reverse blades 320 rotating in different directions, and a vortex space portion 340 formed by spaced apart from the forward and reverse blades 320. do.

The reason for forming a pair of blades 320 rotating in opposite directions with the vortex space 340 in between as described above is because of the first filter member 40 of the photocatalyst media module described above and the second filter member described later. This is because it is difficult to provide a sufficient volume of airflow due to the pressure drop due to the resistance of (400).

That is, as the blowing wind moving on the forward and reverse blades 320 is output while changing the wind direction in the vortex space portion 340, a strong eddy current is generated in the output blowing compared to the blades rotating in the same direction, reducing the resistance of the filter. It can provide strong wind volume to overcome.

Therefore, the structure of the blowing fan 300 of the present invention improves the external air intake efficiency of the air purifier, improves the clean air discharge pressure, and expands the blowing distance of the discharged clean air through the photocatalyst chamber 12. There is an advantage that the output capacity of the sterilized and purified air is increased as the supplied sterilized and purified air is effectively mixed and output through the second filter member 400.

Figure 9 is a diagram showing the internal structure of an air purifier using a photocatalyst media module according to an embodiment of the present invention, located at the upper part of the forward and reverse blades 320 on the discharge passage 16 side of the photocatalyst drum 10. The inner blade 321 is formed to be wider than the outer blade 322 disposed adjacent to the discharge port 220.

Since the width of the blade in the direction of the rotation axis is proportional to the volume (blowing volume) of air discharged from the blowing fan, the wide inner blade 321 is installed in the area corresponding to the discharge passage 16 and is installed in the photocatalyst chamber 12. It performs the role of forcibly pumping the sterilized and purified air, and the sterilized and purified air pumped in this way is quickly discharged by the rotation of the outer blade 322.

Meanwhile, among the forward and reverse blades 320, the outer blade 322 is located adjacent to the discharge port 220 compared to the inner blade 321 located adjacent to the discharge passage 16 of the photocatalyst drum 10. It can be formed with high output.

At this time, the output of the forward and reverse blades 320 may be determined depending on the motor rotation speed or the blade angle.

In this way, when the output of the outer blade 322 is raised higher, a vacuum pressure is created within the vortex space 340, and the sterilized and purified air supplied through the photocatalyst chamber 12 and the second filter member ( Since the filtered air supplied through 400) is effectively mixed and output due to the pressure difference, the filtered air supplied through the second filter member 400 increases the air purification efficiency by ozone and hydroxyl radicals contained in the sterilized and purified air. This improves.

The second filter member 400 according to the present invention is installed in the intake port 210 of the blowing nozzle 200 and is provided to filter intake air.

The second filter member 400 is formed in a tapered shape whose diameter expands toward the inside of the blowing nozzle 200, so that the filtering area for the intake air is expanded.

In the air purifier using the photocatalyst media module of the present invention configured as described above, the sterilized and purified air supplied through the photocatalyst chamber 12 by the operation of the blower fan 300 is supplied through the second filter member 400. There is an advantage that the blowing volume of the sterilized and purified air is greatly increased as the mixing and stirring with the filtered air is effectively performed.

As described above, the most preferred embodiments of the present invention have been described in the detailed description of the present invention, but various modifications may be made without departing from the technical scope of the present invention. Therefore, the scope of protection of the present invention should not be limited to the above-mentioned embodiments, but should be recognized to the technologies in the patent claims described later and to equivalent technical means from these technologies.
