1 is a perspective view schematically showing an ultraviolet water treatment device according to an embodiment of the present invention, Figure 2 shows the inside of FIG.

1 and 2, the ultraviolet irradiation unit 110 may be provided inside the housing 120. Ultraviolet rays generated from the ultraviolet irradiation unit 110 may kill harmful microorganisms by irradiating the ultraviolet light to contaminated water.

The ultraviolet irradiation unit 110 has a shape extending in one direction, and the plurality of ultraviolet irradiation units 110 may be provided in parallel to each other to process a larger amount of water. The ultraviolet irradiation unit 110 may include an ultraviolet lamp and a quartz tube accommodating the ultraviolet lamp.

The temperature sensor 130 monitors whether the temperature of the ultraviolet lamp rises abnormally high. If the temperature of the ultraviolet lamp is ideally high, the first alarm unit 140 may notify the outside of the abnormal high temperature generation of the ultraviolet irradiation unit 110 using at least one of light and sound.

The housing 120 may include a main body 121 having a hollow hollow tube, an inlet 122 and an outlet 123 provided at both sides of the main body 121. Inside the body 121, a plurality of ultraviolet irradiation parts 110 disposed long in one direction may be accommodated.

The inlet 122 and the outlet 123 may be formed to be substantially perpendicular to the main body 121. For example, the UV irradiation unit 110 may be formed in a direction substantially perpendicular to the length direction of the plurality of ultraviolet irradiation units 110. At this time, the inlet 122 and the outlet 123 may be extended so that the central axis is on the same line, the inlet 122 on one side of the main body 121, the other side of the main body 121 The discharge part 123 may be provided.

The valve 150 may be provided at one side of the inlet 122. The valve 150 may operate when a leak of the ultraviolet water treatment device is detected through a leak sensor, which will be described later, to block the inflow of water.

The interior of the main body 121 may be partitioned by partition walls 161 and 162. For example, the inside of the main body portion 121 may include a second region S2 disposed on both sides of the first region S1 and the first region S1 by the first partition 161 and the second partition 162. It may be partitioned into the third region S3. The first region S1, the second region S2, and the third region S3 are all in a spatially separated state. The first region S1 is a region through which water introduced through the inlet 122 passes, and the second and third regions S2 and S3 are portions through which water does not pass.

Since the first region S1 is a region through which contaminated water passes, the ultraviolet irradiation units 110 may be disposed to cross in one direction so that ultraviolet rays may be irradiated with the contaminated water.

Ultraviolet radiation units 110 and the ultrasonic cleaner 170 may be disposed in the first region S1 to cross the first region S1. The ultrasonic cleaner 170 may include a vibrator 171 to remove deposits such as sludge attached to the outer circumferential surface of the ultraviolet irradiator 110. The ultrasonic cleaner 170 may be disposed to be adjacent to the ultraviolet irradiation units 110 to increase the cleaning effect.

The width of the first region S1 may be determined in consideration of the flow rate of the contaminated water passing through the ultraviolet irradiation unit 110, the time the water stays in the first region S1, and the like. For example, the width of the first region S1 may be larger than the width of the inlet 122 and the outlet 123. To this end, the first partition 161 may be disposed outside the extension line of one sidewall of the inlet 122 or the outlet 123 and the second partition 162 may be the inlet 122 or the outlet 123. It may be disposed outside the extension line of the other side wall of the). The contaminated water introduced through the inlet 122 may stay in the first region S1 of the main body 121 provided with the ultraviolet irradiation unit 110 for a while and then be discharged to the outside through the outlet 123. Can be.

In another embodiment of the present invention, the width of the first region S1 may be substantially the same as the width of the inlet 122 and the outlet 123. To this end, the first partition 161 may be disposed on an extension line of one sidewall of the inlet 122 or the outlet 123, and the second partition 162 may be the inlet 122 or the outlet 123. It may be disposed on the extension of the other side wall of the. The contaminated water introduced through the inlet 122 may be discharged to the outside through the discharge unit 123 after passing through the ultraviolet irradiation unit 110 without any obstacles, so that the flow of water may be rapidly maintained.

The first partition wall 161 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. In addition, the second partition 162 may be provided with a hole having the same diameter as the ultraviolet irradiation unit 110 so that the other end of the ultraviolet irradiation unit 110 penetrates. Accordingly, the ultraviolet irradiation part 110 is disposed to cross the first area S1 as a whole, one end penetrates through the first partition wall 161 and is received in the second area S2, and the other end is the second partition wall 162. It may be accommodated in the third area (S3) through the. At this time, the micro-tolerance of the diameter of the ultraviolet irradiation unit 110 and the holes formed in the first partition 161 and the second partition 162 may occur. The rubber packing 165 may be disposed in each hole to prevent water from leaking into the second region S2 or the third region S3 due to such a tolerance.

Since the second region S2 and the third region S3 are regions in which water does not flow in, electrical wiring of the ultraviolet irradiation unit 110 may be formed. For example, the first cable 111 and the second cable 112 for applying power to the ultraviolet irradiation unit 110 may be exposed to the second region S2 and the third region S3, respectively. Since the first and second cables 111 and 112 exposed to the second and third regions S2 and S3 should not come into contact with water, the second and third regions S2 and S3 may be divided into first and second partition walls. By 161 and 162, airtight is maintained, that is, it is a closed state.

The first cable 111 exposed to the second region S2 may be led out through the hollow tube 180 to the third region S3. Thereafter, the first cable 111 may be exposed to the outside through the cable lead-out portion 182 exposed to the outside of the housing 120 together with the second cable 112.

Both ends of the main body 121 are flanged to allow the second region S2 and the third region S3 to be sealed from the outside of the housing 120. At this time, the bolt may be fastened in a state where the rubber packing (120a, 120b) 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 flange couplings and the rubber packings 120a and 120b at both ends of the main body 121 may be used. As a result, water may be kept airtight without leaking to the outside of the main body 121.

Meanwhile, in order to detect whether water is introduced into the second area S2 and the third area S3, that is, whether or not a leak occurs, the water leak sensor 200 is disposed in the second area S2 and the third area S3. Can be deployed. The leak sensor 200 detects a leak when water flows into the second area S2 and the third area S3 and transmits a corresponding signal to a controller (not shown).

Hereinafter, the leak sensor will be described in detail with reference to FIG. 3. 3 is a perspective view showing an extract of a second region portion of the main body portion.

Referring to FIG. 3, the inside of the main body portion 121 is divided into a first region S1 and a second region S2 by the first partition 161, and the ultraviolet irradiation part 110 is formed in the first region ( It is arrange | positioned so that S1 may be crossed and the edge part of the ultraviolet irradiation part 110 is exposed to the 2nd area | region S2. As described above, the leakage sensor 200 for detecting whether the leakage to the second region S2 is disposed in the second region S2 is disposed.

The leak sensor 200 may be disposed on the bottom of the second region S2. The water leaked into the second area S2 is accumulated at the bottom, and the conductors spaced at predetermined intervals constituting the leak sensor 200 may be electrically connected by water. In this way, when the leak sensor 200 detects a leak, the corresponding signal is transmitted to the controller 300.

In the present exemplary embodiment, the case in which the leak sensor 200 is disposed on the bottom surface of the second area S2 is described, but the present invention is not limited thereto. For example, the leakage sensor 200 may be disposed on the main surface of the hole of the first partition 161 to monitor whether the leakage occurs through the hole through which the ultraviolet irradiation unit 110 passes. In another embodiment, it may be arranged that both the bottom of the second area (S2) and the periphery of the hole of the first partition 161 can be disposed.

Figure 4 is a block diagram showing the operation of the ultraviolet water treatment device in the case of leakage occurs in the ultraviolet water treatment device according to an embodiment of the present invention.

Referring to FIG. 4, the controller 300 receives a leak detection signal from the leak sensor 200 to operate at least one of the valve 150, the power supply unit 190, and the second alarm unit 400 based on the leak detection signal. Can be.

The controller 300 may operate the valve 150 provided at one side of the inlet 122 when the leak is detected. The valve 150 may operate according to the valve operation signal of the controller 300 to block the inlet 122. For example, when the ultraviolet irradiation unit 110 is damaged, water flowing through the first region S1 may flow into the second region S2 or the third region S3 through the damaged portion of the ultraviolet irradiation unit 110. . For example, when the degree of breakage is large, water flowing in the first region S1 may rapidly move to the second region S2 and the third region S3 by the flow velocity and the water pressure. In this case, most of the water in the first region S1 may be accommodated by being divided into the second region S2 and the third region S3. To this end, the sum of the volumes of the second region S2 and the third region S3 may be designed to be substantially the same as the volume of the first region.

In addition, when the ultraviolet irradiation unit 110 is damaged and the water in the first region S1 moves to the second and third regions S2 and S3 and the valve 150 operates to block the inlet 122, The secondary accident can be prevented by minimizing the discharge of water to the outside of the ultraviolet water treatment device.

In addition, the controller 300 may cut off the power of the ultraviolet water treatment device based on the leak detection signal. For example, the power of the ultraviolet water treatment device may be cut off by turning off a switch (not shown) of the power supply unit 190.

The controller 300 may operate the second alarm unit 400 based on the leak detection signal. The controller 300 may immediately operate the second alarm unit 400 when a leak detection signal is generated. For example, the second alarm unit 400 may notify the outside of the leakage occurs through at least one of light and sound.

As the second alarm unit 400, when the abnormal high temperature of the ultraviolet irradiation unit 110 occurs, the first alarm unit 140 may be notified to the outside. That is, one alarm unit may inform the outside whether or not an abnormal high temperature occurs in the ultraviolet irradiation unit 110 and a leak occurs. At this time, whether or not the occurrence of abnormal high temperature and leakage may be configured to be easily distinguished by an external user by emitting different light or different sounds.

As another embodiment of the present invention, it is a matter of course that the first alarm unit 140 for notifying the occurrence of abnormal high temperature and the second alarm unit 400 for notifying whether or not the leakage may be provided as a separate member.

Ultraviolet water treatment apparatus according to an embodiment of the present invention can be used in the ship's waste water treatment. In this case, the controller 300 may further include a display unit 410 for displaying the state of the ultraviolet water treatment device to the user of the ultraviolet water treatment device. If a leak occurs in the ultraviolet water treatment device, the controller 300 may transmit an electrical signal to the display unit 410, and the display unit 410 may visually display the ultraviolet water treatment device to the user based on the electrical signal. .

The leak sensor 200 described with reference to FIGS. 1 to 4 has been described in a state provided inside the housing 120, but the leak sensor 500 according to the present embodiment is provided outside the housing 120. Seems to make a difference.

Referring to FIG. 5, the leak sensor 500 may be disposed on the bottom of the housing 120, for example, the bottom of the main body 121. At this time, the bottom of the main body portion 121 is formed to be inclined by a predetermined angle (θ) toward the center so that the leaked water is collected at one vertex when a defect occurs in the housing 120. Can be. At this time, the leak sensor 500 may be disposed at the apex of the bottom surface of the inclined body portion 121.
