One end and the other end of the ultraviolet ray may be fixed on the first side wall 120 and the second side wall 130.

There may be a plurality of ultraviolet lamps 200, and the plurality of ultraviolet lamps 200 may be arranged side by side (parallel). The plurality of ultraviolet lamps 200 may be arranged left and right (y-axis direction) and/or up and down (z-axis direction). When a plurality of ultraviolet lamps 200 are arranged vertically, the ultraviolet lamps 200 may be formed to form multiple layers. The ultraviolet lamp 200 may be formed to form two or more stages.

The plurality of ultraviolet lamps 200 may form a plurality of layers, and each layer may be formed in plural numbers. For example, the ultraviolet lamp 200 may be composed of four layers of two layers. In this case, there may be a total of 8 ultraviolet lamps 200. However, in the present invention, the number of ultraviolet lamps 200 is not limited.

A power application unit 410 is formed in the upper frame 110, and power can be distributed to a plurality of ultraviolet lamps 200.

This sensor unit (S) can simultaneously measure the upper ultraviolet lamp 200 and the lower ultraviolet lamp 200.

For example, when the ultraviolet lamp 200 is arranged in two or more stages, the sensor unit S may be located between each stage. Therefore, the configuration of the ultraviolet lamp 200 - the sensor unit (S) - the ultraviolet lamp 200 can be repeated along the vertical direction (y-axis direction).

The sensor unit (S) may be located in the center between the plurality of ultraviolet lamps 200 arranged vertically. That is, the sensor unit S may be located at a point that is the same distance from each of the ultraviolet lamps 200 arranged vertically.

Referring to FIG. 3(a), the sensor unit S may be located in the center of the four ultraviolet lamps 200. Accordingly, one sensor unit (S) can measure four ultraviolet lamps (200) simultaneously. For example, as shown in FIG. 3(b), one sensor unit S may be located at an equal distance d from the four ultraviolet lamps 200. Accordingly, the sensor unit S can simultaneously measure four ultraviolet lamps 200 and obtain representative values for the illuminance of the four ultraviolet lamps 200.

The existing sensor was located as one above the ultraviolet lamp 200, but in this case, the sensor cannot obtain a representative value for the ultraviolet illuminance of the plurality of ultraviolet lamps 200. On the other hand, in the present invention, the sensor unit (S) is located between a plurality of ultraviolet lamps 200 arranged vertically and can obtain a representative value for the ultraviolet illuminance of the plurality of ultraviolet lamps 200.

It can be.

The control unit 400 is connected to the ultraviolet lamp 200, the sensor unit (S), and the cleaning device 300 and can receive information from the sensor unit (S) and turn on/off the ultraviolet lamp (200). off), the cleaning performance of the cleaning device 300 can be controlled.

Specifically, the control unit 400 may receive the measured illuminance value information from the sensor unit S and control the operation of the cleaning device 300. In particular, when the measured illuminance value is smaller than the preset value, the control unit 400 can drive the cleaning device 300 to ON to clean the outer peripheral surface of the ultraviolet lamp 200.

Here, the “preset value” may be an ultraviolet irradiance value or an input value expected when power is applied. The measured illuminance value may be an output value. That is, if the output illuminance value is smaller than the input illuminance value, the function of the ultraviolet lamp 200 has been deteriorated and the cleaning device 300 can be driven to ON.

Meanwhile, if the measured illuminance value is not recovered even after the cleaning device 300 is turned ON, the control unit 400 may notify/display information about replacement/need repair/failure, etc. for the user.

Additionally, the control unit 400 is connected to the distance measurement unit described above and can receive information from the distance measurement unit. The control unit 400 may determine whether the location of the sensor unit S is located in the center between the two ultraviolet lamps 200 based on the information received from the distance measuring unit. The control unit 400 can correct the position of the sensor unit (S) by controlling the operation of the position adjusting unit.

Additionally, the control unit 400 is connected to the water level detection unit described above and can receive information from the water level detection unit. Here, when the water level is detected to be at a preset level, the control unit 400 can turn on some or all ultraviolet lamps 200.

In addition, the control unit 400 is connected to the above-described wastewater detection unit and can receive information from the wastewater detection unit. Here, the ultraviolet ray intensity (illuminance) of the ultraviolet lamp 200 can be adjusted according to the value of the wastewater detection unit.

Additionally, the control unit 400 is connected to the above-described flow rate detection unit and can receive information from the flow rate detection unit. Here, the ultraviolet ray intensity (illuminance) of the ultraviolet lamp 200 can be adjusted according to the flow rate or flow rate measured by the flow sensor.

Looking at the order, first, as the wastewater flows in and the water level rises, the water level sensor transmits information to the control unit 400, and the control unit 400 turns on the ultraviolet lamp 200 corresponding to the water level, and turns on the corresponding ultraviolet lamp ( The sensor unit (S) capable of measuring 200) can also be driven ON.

When the water level is low, only some ultraviolet lamps 200 can be turned on, and when the water level is high, all ultraviolet lamps 200 can be turned on. In addition, the sensor unit (S) corresponding to the ultraviolet lamp 200 that is turned ON may also be driven ON in conjunction with it.

In addition, when the distance measuring unit measures the position of the sensor unit (S) and transmits the information to the control unit 400, the control unit 400 can determine whether it is appropriately located between the plurality of ultraviolet lamps 200 and move the position. If necessary, the control unit 400 can correct the position of the sensor unit (S) by driving the position control unit.

When the ultraviolet lamp 200 is turned ON, the input value (desired ultraviolet ray intensity (illuminance)) of the ultraviolet lamp 200 may be determined depending on the level of wastewater. If the level of wastewater is high, the input value can also be large.

In addition, when the ultraviolet lamp 200 is turned ON, the input value (desired ultraviolet ray intensity (illuminance)) of the ultraviolet lamp 200 may be determined according to the level of wastewater (pollutant content, type of contaminant, turbidity pH). If the level of wastewater is high, the input value can also be large. For example, if the turbidity is large, the input value can also be large.

In addition, when the ultraviolet lamp 200 is turned ON, the input value (desired ultraviolet ray intensity (illuminance)) of the ultraviolet lamp 200 may be determined according to the flow rate and flow rate of wastewater. If the flow rate and velocity of wastewater are large, the input value can also be large.

Meanwhile, when the ultraviolet lamp 200 is turned on, the ultraviolet ray intensity (illuminance) output by the sensor unit (S) can be measured in real time. That is, the ultraviolet sterilizer of the present invention can be monitored in real time. As a result of monitoring, if the gap between the input value and output value of ultraviolet rays is outside the normal range, the control unit 400 can clean the ultraviolet lamp 200 by operating the cleaning device 300.

For example, the “normal range” may be 0.8 or more and 1 or less. Additionally, the “normal range” may be 1. In this case, if the output value is smaller than the input value, it is treated as abnormal. However, in the present invention, the value of the “normal range” is not limited.

Additionally, if the gap between the input and output values of ultraviolet rays is outside the normal range even after cleaning, the control unit 400 may notify/display information about the situation. Accordingly, the user can know whether the ultraviolet lamp 200 is broken or malfunctioning.
