In general, before the second or third sedimentation treatment sewage in the sewage treatment plant is discharged into the stream, various viruses such as microorganisms contained in the sewage are sterilized. At this time, sterilization methods such as chlorine sterilization, ozone sterilization and ultraviolet sterilization are used.

The chlorine sterilization method, which is widely used in the past, is gradually excluded due to adverse effects such as generation of carcinogens and destruction of river ecosystem due to residual chlorine due to interaction between chlorine and organic matter in sewage.

In addition, ozone sterilization method uses the strong oxidizing power of ozone to inactivate microorganisms and sterilizes. The reaction of ozone and organic matter occurs before the reaction between ozone and microorganisms. Necessity and safety in the operation of the generator is being reluctant to use in the field.

On the other hand, UV sterilization method is degrading microorganisms by radiating ultraviolet rays (C-ray) of 254nm, deactivating microorganisms, and sterilization is possible by only irradiation for a few seconds at an appropriate radiation intensity, which is being evaluated as environmentally friendly.

However, the existing UV sterilizer has a straight line from the inlet to the sterilization to the outlet of the moving water, which shortens the irradiation time of ultraviolet rays (UV) to the flowing water at high speed to completely sterilize biological bacteria. There is a problem.

Therefore, it is possible to solve the above-mentioned problems by providing a constant sterilization effect to the change of the flow rate introduced through the change of the device structure, and also by easily removing the suspended matter (sludge) remaining in the water or the waterway including the ultraviolet sterilizer wall surface. As a new method for the present applicant, the applicant has registered a water sterilization apparatus using an ultraviolet lamp as the Korean Patent Office Publication No. 10-955301.

An enlarged view of the unit area.

First, referring to FIG. 1, the structure of the ultraviolet sterilizing apparatus 1 capable of multi-directional ultraviolet sensing and real-time sterilizing power measurement according to the present embodiment will be described. The ultraviolet sterilizing apparatus 1 includes an ultraviolet sterilizing unit 30 (see FIG. 3). It is provided with a sterilization tube 20 built-in and fixed to the device frame 10 and a control panel 60 coupled to the device frame 10 and electrically connected to the ultraviolet sterilization unit 30.

The device frame 10 is a part forming the appearance of the ultraviolet sterilizer 1 of the present embodiment. The control panel 60 is coupled to the front center area of the device frame 10. Since the ultraviolet sterilizer 1 of the present embodiment may be in contact with water from time to time, most components including the device frame 10 may be made of metal, plastic, glass, etc., which is particularly excellent in corrosion resistance.

Sterilization tube 20 is a tube disposed in the transverse direction of the device frame 10 therein is disposed ultraviolet sterilization unit 30 to sterilize the flowing water. The ultraviolet sterilization unit 30 will be described later. The sterilization tube 20 is provided with a plurality of valve cocks 21 to 23 for drainage at different positions.

2 is a front structural view showing a state in which the ultraviolet sterilizer of Figure 1 is connected to the water flow pipe, the sterilization pipe 20 so that water flows into the sterilization pipe 20, the water flow pipe 50 is Connected. As shown in FIG. 2, the water flow passage 50 includes an inflow line 51 through which water is introduced into the sterilization tube 20, a discharge line 52 through which water is discharged from the sterilization tube 20, and an inflow. It is provided with a connecting line 53 for connecting the line 51 and the discharge line (52). In the structure of the water flow passage 50, the flow meter 55 is provided on one side of the discharge line 52 to measure the flow rate of the water. The flowmeter 55 used in the present embodiment is not limited to the line flowmeter 55 or the scope of the present invention to such matters.

The inlet line 51, the outlet line 52, and the connection line 53 are provided with first to third valves 51a, 52a, 53a for opening and closing the corresponding lines 51, 52, 53. Accordingly, when the third valve 53a is locked, the water flows along the inflow line 51, the sterilization pipe 20, and the discharge line 52 while passing through the flow meter 55. However, when the first and second valves 51a and 52a are locked, the water flows only through the flowmeter 55 without passing through the sterilization tube 20. In this case, when the UV sterilization unit 30 is broken or maintained As such, it may be used to measure only flow rate.

In particular, in the present embodiment, the flow rate value measured from the flow meter 55 is transmitted to the control panel 60, the microcomputer (not shown) provided in the control panel 60 is also collected by the control panel 60 UV sensor The germicidal force is calculated based on the ultraviolet intensity value from 35 and the flow rate value transmitted to the control panel 60. The calculated sterilizing power is displayed on the control panel 60 in real time, so that it is possible to determine whether the device is operating properly or the maintenance time of the device is relatively accurate.

The ultraviolet sterilization unit 30 is provided inside the sterilization tube 20 illustrated in FIGS. 1 and 2 to sterilize by irradiating ultraviolet light to water flowing along the sterilization tube 20. In addition, in the present embodiment, the ultraviolet sterilization unit 30 is attached to the multi-directional ultraviolet sensor rods to enable accurate measurement of ultraviolet intensity. 3 to 6, the ultraviolet sterilization unit 30 simultaneously performs an irradiation function of ultraviolet rays and a detection function of ultraviolet rays intensity.

The ultraviolet sterilization unit 30 is arranged along the circumferential direction to detect a plurality of ultraviolet lamps 33 for irradiating ultraviolet rays and the intensity of ultraviolet rays disposed and irradiated in the central region of the plurality of ultraviolet lamps 33. A plurality of connecting rods 38 connecting the multi-directional UV sensor rods 35, the first and second plates 31 and 32 spaced apart from each other, and the first and second plates 31 and 32. It is provided.

The ultraviolet lamp 33 for irradiating ultraviolet rays is protected by a transparent or translucent first quartz tube 33a, as shown in FIG. 4, and the first quartz tube 33a is formed of a first and a second plate ( 31, 32 are supported along the circumferential direction. In the present embodiment, four first quartz tubes 33a are disposed in the circumferential direction between the first and second plates 31 and 32, but the first quartz having the ultraviolet lamp 33 inserted therein as necessary. The number of tubes 33a can be increased or decreased.

As shown in FIGS. 5 and 6, the ultraviolet sensor rod 35 for detecting the intensity of the irradiated ultraviolet rays may also be protected by a transparent or semi-transparent second quartz tube 35a, wherein the second quartz tube 35a is supported in the central region between the first and second plates 31 and 32. As a result, according to the structure in which the ultraviolet sensor rod 35 is disposed in the center between the ultraviolet lamps 33 arranged in the circumferential direction, there is an advantage that the intensity value of the ultraviolet light can be detected more accurately. Since the second quartz tube 35a is optional, it is not required to be provided and may be replaced with a tube of another material.

In the present embodiment, the ultraviolet sensor rod 35 has a circumference of a rod-shaped sensor rod 35c in which the ultraviolet sensor 35b is disposed in the longitudinal direction of the second quartz tube 35a as shown in FIGS. 5 and 6. It is disposed in three places along the direction, by being spaced at equal intervals in the longitudinal direction of the sensor rod (35c), it is provided with a multi-directional UV sensor rod 35 for detecting the intensity of the ultraviolet light in multiple directions. In the present embodiment, three ultraviolet sensors 35b are shown to be used, but it is a matter of course that the number can be changed to an appropriate number for accurate intensity measurement.

Although the above-described patent document discloses an ultraviolet sensor, the conventional ultraviolet sensor has been attached to one outer surface of the sterilizer and thus has not been able to measure ultraviolet intensity uniformly. In particular, when the ultraviolet sensor is attached to one outer surface of the sterilizer as in the prior art, since only one side intensity of the ultraviolet light emitted from the ultraviolet ray lamp 33 is measured, it cannot be an accurate indicator of the ultraviolet intensity value.

However, by providing a multi-directional UV sensor rod 35 as shown in the present embodiment and arranged in a triangular sphere while rotating the circumference rather than the same line, three places (1, 2, 3) in the longitudinal direction as shown in Figure 6 (a) While measuring, as shown in (b) of Figure 6 can be measured in three places (1, 2, 3) in the circumferential direction it is possible to extract the UV intensity value more precisely than before.

The first and second plates 31 and 32 support portions of the outer first quartz tube 33a and the central second quartz tube 35a by the plurality of connecting rods 38. The first and second plates 31 and 32 may be provided in the same shape and structure, but in this embodiment, the structures and shapes of the first and second plates 31 and 32 are different from each other.

A lamp cap 31a for supporting one side of the first and second quartz tubes 33a and 35a is further used for the first plate 31.

The second plate 32 is further provided with a sealing member 39 coupled to the plurality of through holes 32a to elastically support the first and second quartz tubes 33a and 35a. The sealing member 39 may be formed of rubber or synthetic resin, and it is preferable to use a material resistant to ultraviolet rays. The sealing member 39 is interposed between the second plate 32 and the quartz tubes 33a and 35a as shown in the enlarged view of FIG. 3 to reduce the impact applied to the quartz tubes 33a and 35a, thereby reducing the quartz tube 33a. , 35a) prevents damage. In fact, in the prior art, since the sealing member 39 having such a role is not provided, the quartz tubes 33a and 35a are slightly squeezed by the flow of water, so that the quartz tubes 33a and 35a are often damaged. In the present embodiment, such a phenomenon can be prevented.

Meanwhile, as illustrated in FIGS. 3 and 7, the outer surfaces of the quartz tubes 33a and 35a are movably coupled along the length direction (see arrow in FIG. 7) of the quartz tubes 33a and 35a to form a quartz tube ( The cleaning unit 70 for cleaning the outer surface of the 33a, 35a is further provided.

Since the quartz tubes 33a and 35a are made of transparent or translucent glass, when the quartz tubes 33a and 35a are immersed in the treated water for a long time, the outer surface of the quartz tubes 33a and 35a is contaminated by foreign matter in the treated water. If the outer surfaces of the quartz tubes 33a and 35a are contaminated, the ultraviolet irradiation efficiency or the ultraviolet intensity detection efficiency may deteriorate. In order to prevent this, the cleaning unit 70 is provided.

The cleaning unit 70 serves to wipe the outer surfaces of the quartz tubes 33a and 35a while moving along the length direction (see arrow in FIG. 7) of the quartz tubes 33a and 35a. At this time, in order for the washing unit 70 to move, a means for moving the washing unit 70 is required. For this, as shown in FIGS. 1, 3 and 7, the hydraulic pump 71 and the hydraulic pump ( A unit driving unit 72 is provided to move the washing unit 70 by receiving power from the 71. Of course, it may be considered to use a hydraulic pump or a pneumatic pump instead of the hydraulic pump 71, but the hydraulic pump is difficult to control and the pneumatic pump has a disadvantage of severe noise, so in the present embodiment using the hydraulic pump 71 It is. The unit driving unit 72 may be a cylinder or a piston, and the plurality of washing units 70 may be separated by a separate bracket 75 to operate the plurality of washing units 70 by one unit driving unit 72. It may be supported and then connected to the unit driver 72. The hydraulic pump 71 is arranged in the control panel 60 and is configured to operate according to the operation of the control panel 60.

The connecting rod 38 connects and supports the first and second plates 31 and 32 spaced apart from each other, and a surface of the connecting rod 38 is further provided with a titanium dioxide coating layer as a photocatalyst. Coating of such a photocatalyst can exhibit additional sterilization effect in addition to the sterilization effect from the ultraviolet lamp 33, resulting in better sterilization efficiency.

Meanwhile, as described above, the control panel 60 is coupled to the apparatus frame 10, as shown in FIGS. 1 and 2, and the ultraviolet intensity value from the ultraviolet sensor rod 35 and the flow rate from the flow meter 55. A microcomputer (not shown) which collects flow rate values and calculates sterilizing power based on these values. By setting the display to calculate and show the sterilizing power in a predetermined time unit, the sterilizing power can be checked in real time through the control panel 60.

When the ultraviolet intensity value from the ultraviolet sensor rod 35 and the flow rate value from the flow meter 55 are collected and the sterilizing power is calculated and confirmed based on these values, it is possible to determine whether the ultraviolet sterilizer is operating properly and is easy to use. At the same time, if the sterilization power is low, there is a possibility that a problem occurs in the sterilization device, thus providing various advantages that make it easy to know when to repair the device.

As described above, according to the present embodiment, the intensity of the ultraviolet rays irradiated from the ultraviolet lamp 33 can be accurately sensed, thereby improving sterilization efficiency based thereon. In particular, when the flow meter 55 is provided, the ultraviolet intensity value from the ultraviolet sensor 35 and the flow rate value from the flow meter 55 can be collected and the sterilizing power can be calculated based on these values, so that the sterilizing power can be confirmed in real time. In addition, it is possible to determine whether the device is operating properly and the maintenance time of the device relatively accurately.

As described above, the present invention is not limited to the described embodiments, and various modifications and changes can be made without departing from the spirit and scope of the present invention, which will be apparent to those skilled in the art. Therefore, such modifications or variations will have to be belong to the claims of the present invention.
