First, the housing 130 of the present invention will be described.

The housing 130 includes a main body 131 having a hollow tube, and an inlet 132 and an outlet 133 provided at both sides of the main body 131. At this time, both the inlet 132 and the outlet 133 may be in the shape of a hollow tube.

The inlet 132 may be formed at one side of the main body 131, and the outlet 133 may be formed at the other side of the main body 131. At this time, the inlet 132 and the outlet 133 may extend so that the central axis is in the same line along the direction D2. In addition, the arrangement of the inlet 132 and the outlet 133 may be formed to be approximately perpendicular to the main body 131.

In addition, the inside of the main body 131 may be partitioned by partition walls 171 and 172. For example, inside of the main body 131, the first region S1 and the second region S2 disposed on both sides of the first region S1 by the first partition wall 171 and the second partition wall 172. And the third region S3. The first region S1, the second region S2, and the third region S3 are all spatially separated by the partitions 171 and 172, and the first region S1 flows in through the inlet 132. The water passes through and the second and third areas S2 and S3 are areas where water does not pass. Therefore, the ultraviolet irradiation unit 110 and the photocatalyst plates 120 are accommodated in the first region S1 through which the water passes to sterilize the water.

The width of the first region S1 may be determined in consideration of the flow rate of the contaminated water passing through the housing 130, the time the water stays in the first region S1, and the like. For example, the width of the first region S1 may be greater than the widths of the inlet 132 and the outlet 133. For this purpose, the first partition 171 may be the inlet 132 or the outlet 133. ) May be disposed outside the extension line of one side wall, and the second partition 172 may also be disposed outside the extension line of the other side wall of the inlet part 132 or the outlet part 133. In this way, the speed of the water introduced through the inlet 132 decreases as it passes through the first region S1, so that the water stays in the first region S1 for a longer time, thereby enabling more effective sterilization. do. However, the present invention is not limited thereto, and the width of the first region S1 may be substantially the same as the width of the inlet and the outlet. In this case, the first and second barrier ribs may be disposed on an extension line of the inlet or outlet sidewalls, and in this case, the moving flow of water may be rapidly maintained.

The plurality of ultraviolet irradiation parts 110 and the photocatalyst plates 120 extending in the D2 direction are accommodated in the main body 131. In addition, the inside of the main body 131, the hollow tube 160 for receiving the cables (111, 112) for supplying electricity to the ultraviolet irradiation unit 110 therein, is installed on one side of the inlet 132 to control the inflow of water The valve 150 and a leak sensor 180 for detecting a leak to the second and third regions S2 and S3 may be included.

In addition, both ends of the body portion 131 may be bolted in a state in which the rubber packing (130a, 130b) is interposed. In the event that the ultraviolet irradiation unit 110 is damaged and water flows into the second region S2 or the third region S3, the rubber packings 130a and 130b interposed at both ends of the main body unit 131 The airtightness may be maintained so that water does not leak to the outside of the main body 131.

The ultraviolet irradiator 110 may include an ultraviolet lamp and a quartz tube accommodating the ultraviolet lamp, and penetrate the photocatalyst plates 120 accommodated in the main body 131 to extend in one direction. It is included in the main body 131 of 130. More specifically, the ultraviolet irradiation unit 110 extends in the D1 direction.

In order to process a larger amount of water, a plurality of ultraviolet irradiation units 110 may be provided in parallel with each other. In the present embodiment, three ultraviolet irradiation units 110 are positioned side by side, but the present invention is not limited thereto. Do not. For a higher water treatment effect, a larger number of ultraviolet irradiation units 110 may be arranged in various forms.

In this embodiment, the first partition 171 may be provided with a hole equal to the diameter of the ultraviolet irradiation unit 110 so that one end of the ultraviolet irradiation unit 110 penetrates, and the second partition 172 may have a hole of the ultraviolet irradiation unit 110. A hole equal to the diameter of the ultraviolet irradiation unit 110 may be provided to penetrate the other end. One side of the ultraviolet irradiation unit 110 is accommodated in the second region S2 of the main body 131 and the other side is accommodated in the third region, and is disposed across the first region S1 as a whole. At this time, the micro-tolerance of the diameter of the ultraviolet irradiation unit 110 and the holes formed in the partition walls 171 and 172 may occur, and the water leaks into the second region S2 or the third region S3 by such a tolerance. In order to prevent the rubber packing 173 may be disposed in each hole.

The first cable 111 is connected to one side included in the second region among the two sides of the ultraviolet irradiation unit 110, and the second cable 112 is connected to the other side included in the third region to supply electricity. In this case, the second region S2 and the third region S3 are regions in which water does not flow in, and the first cable 111 and the second cable 112 for applying power to the ultraviolet irradiation unit 110 are respectively. The second region S2 and the third region S3 may be exposed.

The first cable 111 exposed to the second region S2 may be led out through the hollow tube 160 to the third region S3. Thereafter, the first cable 111 may be exposed to the outside through the cable lead-out portion 162 exposed to the outside of the housing 130 together with the second cable 112.

The ultraviolet irradiation unit 110 has a function of killing harmful microorganisms by irradiating the contaminated water with ultraviolet rays generated therefrom. Sterilization by UV rays is proportional to the wavelength, irradiation intensity and irradiation time of UV rays, and the effects may vary depending on the type of microorganism. In the ultraviolet water treatment apparatus according to the present invention, ultraviolet rays having a wavelength of 200 to 350 nm can be generally used in water treatment, and relatively high sterilizing power when the wavelength is around 250 to 270 nm.

The photocatalyst plates 120 are plural, and the photocatalyst plates 120 are arranged in parallel with the photocatalyst plates 120 spaced apart from each other at predetermined intervals along the D1 direction. In addition, the photocatalyst plates 120 may extend in the D2 direction.

At this time, the direction D2 is preferably perpendicular to the direction D1, and the direction D2 is preferably approximately parallel to the direction of movement of water so as not to prevent movement of water passing through the inlet 132 and the outlet 133. In addition, the photocatalyst plates 120 according to the present embodiment are all made of circular plates, but the present invention is not limited thereto and may include various types of plates.

The photocatalyst plates 120 are provided with as many openings as the ultraviolet irradiation unit 110, and the ultraviolet irradiation unit 110 penetrates the openings. In addition, an opening for passing the hollow tube 160 may be additionally formed.

The photocatalyst plates 120 may be manufactured by coating the outer circumferential surface of the steel sheet with TiO ₂ . Alternatively, the photocatalyst plates 120 may be formed by converting titanium to form a TiO 2 layer on an outer circumferential surface thereof. TiO ₂ is It is a stable material with very high oxidizing power. It is a photocatalyst with excellent ability to absorb light and oxidize other materials. Furthermore, it is suitable for use in the ultraviolet water treatment apparatus 100 as the present invention as a non-toxic material that does not affect living organisms. TiO ₂ does not dissolve in aqueous solution, acid, or base solution, and its band gap is 3.0 ~ 3.2 eV, which is relatively large. In the present invention also TiO ₂ The plate absorbs the ultraviolet rays emitted from the ultraviolet irradiation unit and functions to purify the water by killing or photolyzing harmful microorganisms contained in the water. However, the photocatalyst plates 120 according to the present invention are not limited thereto, and may be composed of photocatalysts of other materials except TiO ₂ .

In order to increase the bactericidal disinfection effect, the ultraviolet water treatment device 100 of the present invention preferably includes a large number of photocatalyst plates 120 to increase the surface area in contact with water, and the photocatalyst plates 120 In order not to prevent the movement, the photocatalyst plates 120 may be disposed in parallel with the water traveling direction. In addition, the photocatalyst plates 120 may be formed as thin as possible so that a large number of photocatalyst plates 120 may be included in the main body 131.

The ultrasonic cleaner 140 may be disposed inside the housing 130, particularly in the first region S1. The ultrasonic cleaner 140 may include a vibrator 141, and a plurality of ultrasonic cleaners 140 may be disposed to be adjacent to the ultraviolet irradiation unit 110.

The ultrasonic cleaner 140 functions to remove deposits such as sludge attached to the outer circumferential surface of the ultraviolet irradiation unit 110, which is performed by cleaning by cavitation or by acceleration of water molecules by ultrasonic waves.

The valve 150 is installed at one side of the inlet 132 and operates when a leak of the ultraviolet water treatment device 100 is detected through the leak sensor 180 to block the inflow of water.

On the other hand, the leak sensor 180 for detecting the occurrence of leakage is disposed in the second area (S2) and the third area (S3), when water flows into the second area (S2) and the third area (S3). It detects a leak in and transmits a corresponding signal to a controller (not shown).

The control unit (not shown) receiving the signal from the leak sensor 180 operates the alarm unit 190, which may notify the outside of the leak occurrence through light or sound. In addition, the valve 150 provided at one side of the inlet 132 may be operated, and the valve 150 may operate according to a valve operation signal of a controller (not shown) to block the inlet 132. In addition, the controller (not shown) may cut off the power of the ultraviolet water treatment device 100 based on the leak detection signal.

Next, look at the operation of the ultraviolet water treatment device 100 according to the present embodiment.

When the valve 150 installed at one side of the inlet 132 is opened, water is introduced into the housing 130 through the inlet 132. In the housing 130, the water moves in substantially parallel to the direction D2 shown in FIG. 2 and passes through the first region S1 of the main body 131. In this place, harmful microorganisms in the water which received ultraviolet rays emitted from the ultraviolet irradiation unit 110 are killed, and the process is activated by the photocatalytic action of the photocatalyst plates 120 in this process.

At this time, the width of the first region S1 is greater than the width of the inlet 132 and the outlet 133, so that the water moving inside the housing 130 passes through the first region S1 and the speed is increased. As a result, the time for staying in the first region S1 is increased. That is, as the ultraviolet irradiation time in the first region S1 becomes longer, more effective sterilization effect can be obtained. After that, the water exits the first region S1 and is discharged to the outside through the discharge unit 133.

Simultaneously with the above process, or separately, the ultrasonic cleaner 140 installed inside the housing 130 generates ultrasonic waves by the operation of the vibrator 141 and removes foreign substances attached to the outer circumferential surface of the ultraviolet irradiation unit 110 by the ultrasonic waves. .

By passing through a lattice-shaped passage formed by the irradiation units 110 and the photocatalyst plate 120, a relatively uniform sterilization effect may be enhanced.
