Description

Technical Field

[0001] This utility model relates to the field of ultraviolet disinfection system technology, and more specifically, to an ultraviolet device with detection function. Background Technology

[0002] In ultraviolet (UV) systems, to prevent the charged UV lamps from coming into direct contact with the medium water and to avoid leakage of harmful mercury contained inside the UV lamps due to lamp breakage, which could seriously affect the production process, existing technologies typically use a quartz sleeve between the UV lamps and the medium water for isolation. In addition to isolating the UV system from the medium water, the quartz sleeve also serves to prevent the UV lamps from being damaged by the impact of the fluid medium water.

[0003] During use, water hammer or mechanical damage during installation and transportation can cause tiny cracks in the quartz sleeve, leading to breakage. If the cracks in the quartz sleeve can be detected and replaced in time, damage to the ultraviolet lamp and mercury leakage caused by the breakage of the quartz sleeve can be greatly avoided. Therefore, it is very necessary to monitor the integrity of the quartz sleeve.

[0004] To address the issues of UV lamp damage and mercury leakage caused by quartz sleeve breakage, this application provides a UV device with detection capabilities that can promptly detect cracks in the quartz sleeve, effectively preventing accidents by detecting minute leaks in the quartz sleeve.

[0031] This application provides an ultraviolet device with detection function, which includes an ultraviolet lamp tube 10, a quartz sleeve 20, a first electrode 30, a second electrode 40, and a detection module 50.

[0032] The aforementioned ultraviolet lamp 10 is installed inside the quartz sleeve 20, and there is a gap between the ultraviolet lamp 10 and the inner wall of the quartz sleeve 20 in the circumferential direction. In actual use, both the quartz sleeve 20 and the ultraviolet lamp 10 are cylindrical structures, and they are coaxially arranged during installation. This application does not specifically limit the structure of the inner wall of the quartz sleeve 20, but it is preferably cylindrical or conical.

[0033] The first electrode 30 and the second electrode 40 are disposed between the quartz sleeve 20 and the ultraviolet lamp 10, and the detection module 50 is connected to the first electrode 30 and the second electrode 40. Specifically, the first electrode 30 is disposed at a predetermined vertical height from the bottom of the quartz sleeve 20 and is electrically connected to the detection module 50; the second electrode 40 is disposed between the first electrode 30 and the bottom of the quartz sleeve 20 and is electrically connected to the detection module 50. Specifically, the second electrode 40 can be located anywhere including the first electrode 30, the bottom of the quartz sleeve 20, and any position between them. When their vertical heights are different, electrical connection can only be achieved when the medium water penetrates and simultaneously contacts the first electrode 30 and the second electrode 40, thereby detecting the abnormality.

[0034] Specifically, the preset vertical height is 1.0mm≤h≤2.5mm. This dimension can be adjusted according to the internal dimensions of the quartz sleeve 20 and the external dimensions of the ultraviolet lamp tube 10, with the ultimate goal of achieving accurate detection and avoiding false detection.

[0035] In practical use, condensation easily forms on the quartz sleeve 20. Therefore, both electrodes cannot be placed directly at the bottom of the quartz sleeve 20, otherwise they will be easily affected by the condensation. When the condensation falls to the bottom of the quartz sleeve 20, it may cause both the first electrode 30 and the second electrode 40 to come into contact with the condensation and form an electrical connection. This would cause the detection module 50, the first electrode 30, and the second electrode 40 to conduct through the condensation, resulting in a change in the detection module 50 and leading to a false judgment. Therefore, in this application, the first electrode 30 is set at a preset vertical height from the bottom of the quartz sleeve 20. Only when the permeating medium water reaches the preset vertical height can the first electrode 30 and the second electrode 40 conduct. At this time, the detection module 50 indicates that the quartz sleeve 20 has cracked and is leaking water, thus making the detection more accurate and reliable.

[0036] The ultraviolet device with detection function provided in this embodiment has a first electrode 30 and a second electrode 40 set between the ultraviolet lamp tube 10 and the quartz sleeve 20, and sends electrical signals to the two electrodes in real time. When a crack appears in the quartz sleeve 20, and a small amount of medium penetrates into the quartz sleeve 20, the penetrating medium electrically connects the two electrodes, causing a change in the resistance value between the two electrodes. The change in resistance value is transmitted to the detection module 50. After detecting the change in resistance value, the detection module 50 promptly issues an alarm signal. The issuance of this alarm signal can be achieved by setting an alarm on the quartz sleeve 20, so that the abnormal situation can be transmitted to the staff more promptly. Specifically, the alarm includes both a sound alarm and a light alarm. The sound alarm can transmit the abnormal situation more quickly and promptly, and the light alarm can help the staff quickly locate the abnormal location. Preferably, the alarm is installed at the outer end of the quartz sleeve 20 outside the ultraviolet system to better perform the alarm function.

[0037] According to the above scheme, it is possible to determine whether the quartz sleeve 20 has cracked and is leaking, and to promptly detect and replace the quartz sleeve 20 if cracks occur, greatly avoiding damage to the ultraviolet lamp 10 and mercury leakage caused by damage to the quartz sleeve 20. Furthermore, setting the first electrode 30 at a predetermined vertical height from the bottom of the quartz sleeve 20 effectively avoids false detections caused by a small amount of condensation at the bottom of the quartz sleeve 20, further improving the accuracy of the detection.

[0038] In a preferred embodiment of this application, the first electrode 30 and the second electrode 40 are installed such that there is a lateral gap between them, that is, their projections on the horizontal plane do not overlap. Figure 4 As shown. This setting is to prevent condensate from dripping onto both the first electrode 30 and the second electrode 40 simultaneously when falling vertically, thus avoiding potential false detections and making the detection more efficient and accurate.

[0039] Specifically, the aforementioned lateral spacing d∈0,L], where L is the maximum internal lateral dimension of the quartz sleeve 20 at a preset vertical height h. For example, when the first electrode 30 is disposed on the inner wall of the quartz sleeve 20 and the second electrode is disposed on the inner wall of the quartz sleeve 20 at the same preset vertical height on the side opposite to the first electrode 30, the lateral distance between them is L; when the first electrode 30 is disposed on the inner wall of the quartz sleeve 20 and the second electrode 40 is disposed at the bottom of the quartz sleeve 20, the lateral distance between them is L / 2.

[0040] Preferably, at least one of the first electrode 30 and the second electrode 40 is located in the gap between the quartz sleeve 20 and the ultraviolet lamp tube 10, so as to avoid the situation where condensate flows through both of them at the same time when they are installed on the inner wall of the quartz sleeve 20.

[0041] In one embodiment of this application, the first electrode 30 is disposed in the gap between the ultraviolet lamp tube 10 and the inner wall of the quartz sleeve 20 in the circumferential direction, and the second electrode 40 is disposed at the bottom of the quartz sleeve 20.

[0042] In this embodiment, as Figure 1 As shown, the first electrode 30 and the second electrode 40 can be disposed on the same cross-section, or they can be disposed axially back and forth inside the quartz sleeve 20, without any restrictions on their specific installation positions. Furthermore, since the second electrode 40 is installed at the bottom of the quartz sleeve 20, the first electrode 30 is preferably disposed at a predetermined vertical height from the bottom of the quartz sleeve 20, but with a gap maintained between it and the inner wall of the quartz sleeve 20. This gap allows condensate to pass through smoothly without contacting the first electrode 30.

[0043] In another embodiment, the first electrode 30 is disposed on the inner wall of the quartz sleeve 20, and the second electrode 40 is disposed in the gap between the ultraviolet lamp tube 10 and the inner wall of the quartz sleeve 20 in the circumferential direction, and the second electrode 40 and the first electrode 30 are on the same horizontal plane, such as... Figure 3 As shown.

[0044] At this time, it is also possible to... Figure 5 As shown, the first electrode 30 and the second electrode 40 are on the same horizontal plane, but both the first electrode 30 and the second electrode 40 are located in the gap between the ultraviolet lamp tube 10 and the inner wall of the quartz sleeve 20 in the circumferential direction, that is, neither of them is in contact with the inner wall of the quartz sleeve 20.

[0045] Of course, the specific installation positions of the first electrode 30 and the second electrode 40 in this application are not limited to the above embodiments. The first electrode 30 only needs to be set at a preset vertical height, and its specific position relative to the quartz sleeve 20 is not specifically limited. Similarly, the second electrode 40 can be located at any height including the bottom of the first electrode 30 and the quartz sleeve 20 and between them, but its specific installation position relative to the quartz sleeve 20 is not limited, so as to achieve efficient and accurate leakage detection effect.

[0046] Specifically, such as Figures 1 to 5 The diagram shows a structural schematic with the first electrode 30 and the second electrode 40 positioned at different locations. Figure 2 This illustrates the structure when the second electrode 40 is positioned between the first electrode 30 and the quartz sleeve 20.

[0047] In this application, when the electrode is positioned in the gap, it can be mounted at the target location using a support, or supported and fixed using other feasible methods such as thickening the colloid. In this case, the supporting and fixing components are preferably made of insulating material. When using a support for installation, the electrode can be detachably mounted on the support, facilitating inspection and maintenance during use.

[0048] In one embodiment of this application, an installation mark is preferably provided on the outer periphery of the quartz sleeve 20 to facilitate more accurate determination of the installation angle and direction of the quartz sleeve 20 during installation. Specifically, a marking line can be provided at the bottom of the quartz sleeve 20. During installation, the marking line is located at the bottommost point and in contact with the ultraviolet system to ensure more accurate installation direction, thereby enabling the detection module 50 to perform leak detection more accurately.

[0049] The aforementioned detection module 50 includes a power generator, a waveform generator, a signal processing generator, a comparator, and a reference voltage source. For example... Figure 6 and Figure 7 As shown, the output voltage of the power generator is connected to the input terminal of the waveform generator; the output terminal of the signal processor is connected to the positive input terminal of the comparator; and the output voltage of the reference voltage source is connected to the negative input terminal of the comparator. The power generator generates the required voltage according to the instructions issued by the controller; the waveform generator shapes the input voltage waveform to generate the required standard waveform; when the quartz sleeve 20 has a crack and water seepage causes the first electrode 30 and the second electrode 40 to be electrically connected, the standard waveform generated by the waveform generator passes through the detection band-electrode-detection band, feeding back the modulated detection signal to the signal processor. The signal processor processes the detection signal transmitted from the inspection band and amplifies it; the comparator compares the detection signal with the reference voltage and outputs the inspection result.

[0050] The leak detection module determines whether a leak is occurring by detecting feedback signals and processes the results or outputs them to an external system for further processing. Processing methods may include indicator light display or buzzer alarm. The leak detection process is performed in real-time during system operation. Once a leak is detected, the system stops supplying power to the lamps. Once the leak is resolved, the system returns to normal operation.

[0051] In actual use, the ultraviolet system includes multiple ultraviolet lamps 10 and quartz sleeves 20. Therefore, it is necessary to simultaneously inspect multiple sets of ultraviolet lamps 10 and quartz sleeves 20. In this case, locating the abnormality is particularly important for timely replacement of broken quartz sleeves 20. Preferably, each quartz sleeve 20 is equipped with a corresponding identification element. The detection module 50 is connected to the identification element, and the identification element feeds back the position information of the corresponding quartz sleeve 20 to the detection module 50. With this setup, each identification element can feed back the position information of its corresponding quartz sleeve 20. Thus, after water seepage occurs, the detection module 50 directly obtains the information from the identification element and displays or broadcasts this information to the staff when an alarm is triggered, making replacement more timely and greatly preventing the further damage to the ultraviolet lamps 10 caused by a broken quartz sleeve 20.

[0052] Of course, the ultraviolet lamp 10, the quartz sleeve 20 and the detection module 50 can also be set up as a group, that is, each detection module 50 detects a corresponding quartz sleeve 20. When a quartz sleeve 20 leaks water, the corresponding detection module 50 will sound an alarm. Different detection modules 50 are in different positions, which also greatly improves the efficiency of replacement.

[0053] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
