Description

Technical Field

[0001] This utility model belongs to the field of disinfection system technology, and more specifically, it relates to a monitoring, feedback, adjustment and control system for ultraviolet disinfection equipment. Background Technology

[0002] Ultraviolet (UV) light is light with wavelengths shorter than visible light in the electromagnetic spectrum, ranging from approximately 10 nm to 400 nm. Short-wave UV light at 253.7 nm has the highest sterilization efficiency. UV light works by damaging the DNA of microorganisms, causing them to lose their reproductive ability or die directly, thus achieving sterilization. UV light has significant advantages over other disinfection methods, but its effectiveness is influenced by many factors, including UV dose, water turbidity, contact time, and water volume.

[0003] The optimal choice for ultraviolet (UV) disinfection is to achieve energy savings and reduced consumption during operation while still meeting disinfection requirements. Currently, most UV disinfection equipment on the market lacks a monitoring, feedback, and control system, resulting in problems such as high cost, low efficiency, and lack of automated management. Furthermore, existing operation and maintenance systems are often simplistic, merely monitoring UV intensity or lacking fault alarm functions, thus failing to fully realize the disinfection effect. Utility Model Content

[0004] The purpose of this invention is to provide a monitoring, feedback, adjustment, and control system for ultraviolet disinfection equipment, which aims to solve the problem of being unable to provide effective data feedback on the disinfection effect and operation status of the ultraviolet disinfection system.

[0016] In one possible implementation, the turbidity monitor includes a light source, a lens, and an intensity monitor, the intensity monitor using the water-scattered light received by the lens to determine the turbidity.

[0017] In one possible implementation, both the light source and the lens are positioned inside a probe tube, which is a bent tube.

[0026] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] Please refer to the following: Figures 1 to 3 This invention provides a monitoring, feedback, adjustment, and control system for an ultraviolet (UV) disinfection device. The system includes: a control station, a UV disinfection device, a flow monitoring device, an intensity monitoring component, and a host computer. The UV disinfection device is electrically connected to the control station and positioned within the inlet water pipeline for disinfection. The flow monitoring device is electrically connected to the control station and is spaced apart from the UV disinfection device. The intensity monitoring component is electrically connected to the control station and located behind the UV disinfection device for monitoring the intensity of UV light within the inlet water pipeline and the disinfection effect. The host computer is connected to the control station and receives data feedback from it.

[0028] The beneficial effects of the ultraviolet disinfection equipment monitoring, feedback, and adjustment control system provided by this utility model are as follows: Compared with the prior art, in this ultraviolet disinfection equipment monitoring, feedback, and adjustment control system, the control station is electrically connected to the ultraviolet disinfection equipment, the flow monitoring device, and the intensity monitoring component. The ultraviolet disinfection equipment is positioned inside the water inlet pipeline for disinfection. The flow monitoring device is spaced apart from the ultraviolet disinfection equipment, and the intensity monitoring component is located in front of the ultraviolet disinfection equipment to monitor the intensity of ultraviolet light and the disinfection effect in the water inlet pipeline. Finally, the host computer receives data feedback from the control station. Through the above settings, a good disinfection effect is achieved, and more detailed and accurate monitoring of the liquid state in the pipeline is realized. Through the feedback of relevant data, automatic monitoring of the disinfection effect is ensured, the level of interaction is improved, and safety hazards are eliminated.

[0029] This application can be considered as consisting of ultraviolet disinfection equipment, intensity monitoring components, power monitoring devices, a PLC station, a flow monitoring device, a host computer, and a cloud monitoring system. The ultraviolet disinfection equipment is divided into three groups, spaced apart from each other, and can operate independently, using ultraviolet lamps to disinfect the water channel with C-band ultraviolet light. The intensity monitoring components, through the integration of ultraviolet light intensity monitors, turbidity monitors, and flow detectors, monitor the effective dosage of ultraviolet disinfection and the status of the ultraviolet disinfection module in real time, and transmit the data to the PLC station. The PLC station and the host computer are bidirectionally connected. The host computer not only displays the data parameters uploaded by the PLC station and those calculated by the microprocessor in real time, but also has control functions for each module of the system. When any data exceeds a set reasonable threshold, the system quickly responds with an alarm. The cloud monitoring system is connected to the host computer to realize remote monitoring via the Internet of Things, and the power monitoring system monitors the overall power consumption of the system.

[0030] Ultraviolet (UV) disinfection is quick and efficient, completing the process in just one second. It is effective against a wide range of microorganisms, including various bacteria, pathogens, and parasites. UV disinfection is environmentally friendly and does not pollute water bodies or the surrounding environment. UV disinfection equipment operates quietly and odorlessly, ensuring safe and reliable operation, and is currently widely used.

[0031] Please refer to some embodiments of the ultraviolet disinfection equipment monitoring feedback adjustment and control system provided in this application. Figure 1 The ultraviolet disinfection equipment, flow monitoring device, and intensity monitoring component are all present in multiple units. The ultraviolet disinfection equipment uses a high-efficiency, high-intensity, and long-life UVC disinfection device, with a specially designed high-efficiency ultraviolet lamp radiating strong ultraviolet C light with a wavelength of 253.7nm. In this embodiment, three ultraviolet disinfection devices, flow monitoring devices, and intensity monitoring components are selected.

[0032] The ultraviolet (UV) lamps and auxiliary equipment together constitute the UV disinfection system. The entire system is placed in a parallel-flow channel within the disinfection channel, i.e., the inlet and outlet pipelines, with the UV lamps arranged parallel to the water flow. A movable fiberglass or galvanized carbon steel grating plate is added to the top of the disinfection channel. All parts in contact with wastewater are made of corrosion-resistant 316 stainless steel. The UV lamps are low-voltage, high-intensity models, typically with a power of 320W. Human factors such as lamp ballast design, cleaning and maintenance, and water flow control can all affect the actual disinfection results. Therefore, real-time online monitoring of the disinfection effect and immediate adjustment of the disinfection equipment based on feedback from various influencing factors are crucial for ensuring disinfection effectiveness and reducing costs while increasing efficiency.

[0033] Please refer to some embodiments of the ultraviolet disinfection equipment monitoring feedback adjustment and control system provided in this application. Figure 2 The flow monitoring device includes a control valve and a flow meter; the control valve is used to open or close the inlet pipeline, and the flow meter is used to measure the flow rate in the inlet pipeline.

[0034] In practical applications, the system includes a main inlet channel, three branch gates, and three branch disinfection pipelines. Each of the three disinfection pipelines is equipped with an inlet valve and an outlet valve. Finally, the disinfected water from the three disinfection pipelines will converge.

[0035] The purpose of this application is to achieve effective ultraviolet disinfection and real-time online monitoring of equipment by setting up a comprehensive monitoring system with complete operating parameters. To this end, a pre-configured microcontroller can automatically adjust and control based on the collected data. A remote control module combined with IoT cloud technology (i.e., a cloud-based monitoring module) enables remote, cloud-based intelligent control interaction. The LCD display on the PLC station intuitively displays parameters such as ultraviolet dosage, disinfection equipment status, cleaning progress, and reactor chamber temperature to the user. An alarm is triggered when thresholds are exceeded, promptly reminding the user to address and eliminate safety hazards. This achieves integrated display and control with automatic monitoring, feedback, and adjustment functions.

[0036] In some embodiments of the ultraviolet disinfection equipment monitoring feedback adjustment and control system provided in this application, the ultraviolet disinfection equipment includes an ultraviolet lamp, a driving device, and a cleaning device; the driving device drives the cleaning device to move for cleaning the ultraviolet lamp.

[0037] Germicidal ultraviolet lamps are low-pressure, high-brightness amalgam lamps. A single lamp can have a maximum power of 320W. They feature a preheating mechanism and a robust filament capable of withstanding impact and vibration. They do not produce ozone and have a lifespan of 12,000-20,000 hours. Each UV lamp is enclosed in an independent, high-purity, high-transmittance (>90%) quartz sleeve. One end of the sleeve is closed and fixed, while the other flared, open end is sealed within the electrical enclosure. The lamps are insulated from each other, providing the highest dust and water resistance rating of IP68.

[0038] The sensors in the intensity monitoring assembly are installed underwater, with only one set of intensity monitoring assemblies required for each canal. The sensors are connected to the analog input port on the communication control board in the power distribution center. The drive unit is pneumatic, and the pneumatic drive unit is mounted on a stainless steel casing outside the ultraviolet lamp.

[0039] In the automatic pneumatic drive system, the submersible pneumatic drive unit on each ultraviolet lamp module drives the cleaning device to move along the stainless steel casing, thereby completing the cleaning of the lamp tube.

[0040] Please refer to some embodiments of the ultraviolet disinfection equipment monitoring feedback adjustment and control system provided in this application. Figure 1 and Figure 2 The intensity monitoring components include an ultraviolet light intensity monitoring device, a flow meter, a flow velocity meter, a turbidity monitor, and a UV dose monitoring center. In practical applications, the turbidity monitor relies on 880nm infrared light. Infrared light passes through an optical lens to receive the scattered light from impurities in the water at a 90° angle, thus indirectly reflecting the effectiveness of ultraviolet sterilization.

[0041] The flow rate sensor has a base at its bottom for easy installation on pipes. It can be powered in various ways, including by a battery module, depending on the specific requirements. The flow rate sensor also includes a wireless transmission kit, allowing monitoring data to be displayed on a data transmission terminal.

[0042] The UV intensity of the UV lamps is monitored in real time using a UV intensity sensor to understand the lamp's attenuation status. The UV intensity sensor is positioned near the UV disinfection equipment and uses the photoelectric effect to reflect the intensity of UV light in the water, providing a direct representation of the system's operational effectiveness. The effective UV dose data is calculated based on the UV system's operating time. This device is primarily used to collect effective dose data from the UV disinfection system, achieve real-time monitoring, provide signal feedback, and output UV dose data. In addition to monitoring UV light intensity, the entire UV monitoring feedback and control system is also monitored, including the status of each module or UV lamp, lamp operating time, reactor voltage settings, and the cleaning system's operational status.

[0043] Please refer to some embodiments of the ultraviolet disinfection equipment monitoring feedback adjustment and control system provided in this application. Figure 2 The flow meter 1 is positioned above the water level observation point via the bracket 2; the velocity meter is positioned inside the inlet pipeline via the base. The probe of the ultrasonic open channel flow meter 1 is installed above the water level observation point of the measuring weir. The probe is fixed by the probe bracket 2, and its emitting surface must be aligned with the water surface and perpendicular to the water surface.

[0044] When the water level is lower than the preset water level and cannot submerge the top row of ultraviolet lamps, a signal is transmitted to the single channel controller in the single channel control station, which cuts off the power supply to the corresponding lamp and issues an alarm, putting the equipment into a protection state. When the automatic water level controller detects the water level recovery signal, the module automatically resumes operation.

[0045] Please refer to some embodiments of the ultraviolet disinfection equipment monitoring feedback adjustment and control system provided in this application. Figure 3 The turbidity monitor includes a light source, a lens, and an intensity monitor. The intensity monitor uses the scattered light from the water received by the lens to determine the turbidity. The online monitoring system interface of this invention includes data such as UV intensity, flow rate, and UVT for characterizing the ultraviolet reactor, allowing real-time monitoring of water quality and quantity, reflecting the sterilization effect, and real-time monitoring of the operating status, operating time, and number of lamp starts and stops for each lamp. An alarm is triggered when a UV lamp malfunctions or reaches the end of its lifespan. The system displays the cleaning frequency, cleaning time, and cleaning progress of the online mechanical cleaning system (i.e., the cleaning device). The cleaning frequency and cleaning time can be adjusted according to water quality and quantity. The temperature of the ultraviolet reactor chamber is displayed and recorded in real-time. When the reactor temperature is too high, an alarm is triggered and the system protection program is activated, shutting down or reducing the power of the ultraviolet reactor. Online monitoring data and alarm data are archived in historical data and records, which can be accessed by operators at any time.

[0046] Please refer to some embodiments of the ultraviolet disinfection equipment monitoring feedback adjustment and control system provided in this application. Figure 3 The light source and lens are both positioned inside the detection tube 4. The detection tube 4 is a bent tube and is slidably mounted on the mounting base 5. A swing rod 3 is fixed on the detection tube 4. The swing rod 3 passes through the mounting base 5 and is rotatably mounted on the mounting base 5.

[0047] In order to change the height and swing angle of the probe tube 4 according to the actual use requirements, the mounting base 5 is first fixed. The mounting base 5 is fixed to the structure by means of expansion bolts, etc. The swing rod 3 is fixed on the probe tube 4. The swing rod 3 is set in the vertical direction, passes through the mounting base 5 and can slide up and down along the mounting base 5. After the probe tube 4 is slid to a certain height, the probe tube 4 can be positioned by tightening the bolts on the upper and lower sides of the mounting base 5. At this time, the swing rod 3 can be opened with external threads, and the positioning is achieved by the threaded engagement of the swing rod 3 with the bolts, etc.

[0048] The lever 3 can swing relative to the mounting base 5, which allows the orientation of the probe tube 4 to be adjusted accordingly.

[0049] Please refer to some embodiments of the ultraviolet disinfection equipment monitoring feedback adjustment and control system provided in this application. Figure 1 and Figure 2 The ultraviolet disinfection equipment, flow monitoring device, and intensity monitoring component are all connected to a power monitor. The power distribution center provides power to all equipment, modules, and devices. It is connected to the ultraviolet disinfection equipment via cables and has a communication control board. The communication control board transmits signals to the ultraviolet disinfection equipment, and the power distribution center can transmit data with the system control center.

[0050] The automatic water level controller is used to control the water level in the disinfection channel. The signal is connected to the single-channel controller in the single-channel control cabinet to realize automatic water level control. The sensor is connected to the upper communication port via a cable. The cable extends from one end, runs along the groove at the bottom of the module, and finally connects to the analog input port on the communication control board in the power distribution center.

[0051] Please refer to some embodiments of the ultraviolet disinfection equipment monitoring feedback adjustment and control system provided in this application. Figure 1 The control station is a PLC station; the host computer is connected to a cloud monitoring module. The system control center user interface uses touch screen technology for operation, and the system control center contains the control program for the ultraviolet system. The microcontrollers are pre-configured with inputs and outputs according to the requirements of each system at the factory. ONYX configures the function of each signal card in the control strategy. Daily operation includes monitoring system functions, and may occasionally require manual start-up or control of the process by the operator. This utility model uses a 485 communication signal for remote control operation.

[0052] This utility model's online ultraviolet effective dose monitoring system is a comprehensive control system that collects, analyzes, and calculates data online, displays the effective dose in real time, and controls the ultraviolet disinfection system. The monitoring system utilizes Internet of Things (IoT) and cloud technology; the equipment's operating status is displayed in a cloud-based monitoring center and can be monitored and adjusted via a mobile app, making operation more convenient and intelligent. The microcontroller is pre-configured with inputs and outputs according to the requirements of each system at the factory, and has a built-in synchronous control program that can automatically adjust the disinfection level based on data.
