Technical Field

[0001] The invention relates to the technical field of disinfection, in particular to an energy-saving self-regulating NSTG-UVC disinfector for gardening. Background Art

[0002] As modern horticulture and agricultural production have increasingly stringent requirements for water quality management, especially in high-density planting environments such as greenhouses, pathogens in water (such as bacteria, viruses, fungi, etc.) may pose a serious threat to crop health. Traditional water treatment methods cannot accurately perform targeted disinfection based on water quality and pathogen type, leading to problems such as over-disinfection, high energy consumption, or poor disinfection effects. In addition, factors such as the aging of ultraviolet lamps in the system, incomplete water filtration, and pathogen resistance can also affect disinfection efficiency.

[0003] In order to solve these problems, it is necessary to develop an intelligent and automatically adjustable disinfection machine. The energy-saving self-adjusting NSTG-UVC disinfection machine for horticulture proposed in this application can dynamically adapt to changes in water quality and eliminate pathogens in the water efficiently and energy-savingly, ensuring the disinfection effect while optimizing resource utilization.

[0004] Patent document CN115227852B discloses a disinfection machine. The above patent realizes that the disinfectant in the depressurization chamber can be vaporized by providing a relatively low temperature through a heating device. The vaporized disinfectant is sprayed into the external environment with the high-speed airflow in the exhaust pipe for disinfection. While ensuring the vaporization effect of the disinfectant, the decomposition rate of the disinfectant is reduced, the disinfection effect is improved, and the vaporized disinfectant can be more efficiently diffused into the external environment under the action of the high-speed airflow. However, the above patent cannot realize the adaptive learning and adjustment function of the disinfection operation.

[0005] Patent document CN103060835B discloses a disinfection machine, which realizes that the disinfectant in the electrolytic cell is sent out through a liquid circuit and sprayed directly on the hands for disinfection or sprayed for disinfection after switching. It is an efficient, environmentally friendly, economical and convenient disinfection equipment suitable for homes and public places, but the above patent cannot realize the detection and adjustment function of water transparency.

[0006] Patent document CN102389581B discloses a disinfection machine. The above patent realizes flushing the inner wall of medical device components such as endoscopes through an inner wall flushing nozzle, and flushing the outer wall of medical device components such as endoscopes with an automatic rotating spray mechanism to rinse the residues on medical device components such as endoscopes. Therefore, the above disinfection machine has a good disinfection effect, but the above patent cannot realize the function of detecting the type and concentration of pathogens in water.

[0007] Patent document CN110419966B discloses a fruit and vegetable sterilizer. The above patent realizes that the electrolysis module can be taken out of the shell at any time for cleaning or replacement, which is beneficial to extend the service life of the fruit and vegetable sterilizer and ensure the electrolysis efficiency of the fruit and vegetable sterilizer. However, the above patent cannot realize the ultraviolet light intensity output adjustment function.

[0008] In summary, the above patents cannot realize the adaptive learning and adjustment function of disinfection operation, the detection and adjustment function of water quality transparency, the detection function of pathogen types and concentrations in water, and the ultraviolet light intensity output adjustment function, resulting in poor disinfection effect of manual intervention, inability to adapt to the disinfection requirements of different water bodies and pathogens, unstable disinfection and high energy consumption;

[0024] The automatic water mixing valve adopts a three-way valve. When the T10 value is lower than the set value, the system automatically opens the water mixing valve to mix the clean water and wastewater in proportion. The mixing ratio is adjusted by the proportional control valve installed on the automatic water mixing valve. The proportional adjustment range is 0-100%, and the maximum mixing flow rate is 5m 3 / h, the control system dynamically adjusts the opening of the mixing valve according to the T10 value sensor data, so that the T10 value is always kept in the set safety range.

[0025] Preferably, a dynamic flow rate control module is also installed in the UV disinfection box, and the dynamic flow rate control module is used to detect the water flow rate in real time and perform dynamic adjustment;

It can also detect the concentration of pathogens in the water. The concentration detection range is 10 3 -10 6 CFU / ml;

[0033] The automatic dose adjuster automatically calculates the required UV-C dose based on the pathogen concentration and type fed back by the pathogen sensor. When the pathogen sensor detects a change in pathogen concentration, the control system can send a signal through the automatic dose adjuster to adjust the UV lamp dose in real time.

[0034] The control system has a built-in pathogen database that covers the disinfection dosage requirements of common pathogens. The database is updated regularly to support users to import new pathogen data as needed.

[0035] Preferably, the light intensity automatic adjustment module is used to automatically adjust the output light intensity of the UV-C lamp according to the aging condition of the ultraviolet lamp, the ambient light intensity and the water quality conditions;

[0036] The light intensity automatic adjustment module includes: light intensity sensor, light intensity regulator and aging compensation mechanism;

[0037] The light intensity sensor uses an ultraviolet radiation intensity sensor, which is installed on the side of the inner wall of the UV box to monitor the radiation intensity of the ultraviolet lamp in real time. The monitoring range is 0-500mj / cm 2 , with an accuracy of ±2%. The light intensity sensor combines with the working market of the ultraviolet lamp to automatically detect the degree of lamp aging and prompt lamp replacement based on the attenuation of radiation intensity;

[0038] The light intensity regulator adopts PWM control, which controls the current supply of the UV lamp through PWM technology, adjusts the light intensity output, and ensures that the light intensity is automatically adjusted to the optimal level when the light ages / water quality changes. The adjustment range is 60-100% light intensity output. The control system can automatically select three levels of light intensity output mode according to water quality and pathogen type;

[0039] The aging compensation mechanism means that an automatic compensation algorithm is designed into the control system. As the ultraviolet lamp ages, the light intensity decays. The control system increases the current supply through the automatic compensation algorithm to slow down the rate of light intensity decay.

[0040] Preferably, the UV-C box is also designed with a modular filtration and descaling system, which is used to filter water and prevent dirt on the quartz tube from affecting the ultraviolet transmittance;

[0044] The automatic descaling device uses a weak acid solution to regularly clean the surface of the quartz tube to dissolve the deposits. The acid cleaning time interval is set by the control system.

[0045] Preferably, the disinfection machine is also equipped with an energy recovery system, which is used to recover the excess heat generated by the ultraviolet lamp when it is working;

[0047] A plate heat exchanger and cooling fins are installed on the outer wall of the UV box. The heat exchanger is made of 316 stainless steel.

[0048] The temperature sensor is installed on the outer wall of the UV box. The temperature sensor detects the temperature of the UV box in real time. When the temperature is higher than 60℃, the heat recovery device is automatically started to transfer excess heat to other systems.

[0049] The heat transfer system uses PPR pipes to connect the heat exchanger and the greenhouse heating system to provide heat for the horticultural greenhouse.

[0050] Preferably, the machine learning model used in the AI ​​algorithm is a long short-term memory network model;

[0066] Figure 3 It is a schematic diagram of the disinfection process of the present invention. DETAILED DESCRIPTION

[0067] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] See also Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: an energy-saving self-regulating NSTG-UVC disinfection machine for gardening, comprising an ultraviolet disinfection core module, an automatic T10 value detection and adjustment module, an intelligent pathogen identification module, a light intensity automatic adjustment module and a self-learning adjustment algorithm module, wherein the automatic T10 value detection and adjustment module, the intelligent pathogen identification module and the light intensity automatic adjustment module are connected to the self-learning adjustment algorithm module through a data acquisition system, and the self-learning adjustment algorithm module is connected to the ultraviolet disinfection core module and the control system through a data signal control harness;

[0069] The self-learning adjustment algorithm module includes: a data acquisition system, an AI learning algorithm and an adaptive optimization control mechanism, and the self-learning adjustment algorithm module is used to perform disinfection control adjustment optimization according to historical disinfection data;

[0070] The data acquisition system collects water quality parameters, flow, light intensity and pathogen concentration with a sampling frequency of 1 time / minute and a data storage capacity of 1000 samples;

[0071] The AI ​​learning algorithm analyzes the collected historical data through the multi-layer neural network built into the machine learning model to automatically optimize the water flow rate, light intensity and disinfection dosage settings;

[0072] The adaptive optimization control mechanism is that the control system automatically updates the model every 100 hours of operation, automatically adjusts the working time and power of the ultraviolet lamp through the control system, and adjusts the disinfection dosage by predicting the historical changes in pathogen concentration;

[0073] The machine learning model used in the AI ​​algorithm is a long short-term memory network model;

[0074] The model run consists of the following steps:

[0075] Data collection and preprocessing: Collect water quality data, flow rate data, light intensity data, pathogen data and historical operation data, and process missing values ​​and standardize the data;

[0076] Model training and optimization: Model training is performed using historical data, and cross-validation methods are used to evaluate model performance;

[0077] Self-learning and automatic adjustment: Automatically adjust model parameters through online learning mechanism;

[0078] Furthermore, the control system automatically adjusts the light intensity output of the UV lamp according to the pathogen concentration, water quality and aging of the UV lamp, ensuring that the UV-C dose meets the actual needs. When the pathogen concentration is low, the model predicts that a low dose of UV-C can achieve the disinfection effect, reduce the light intensity output, and reduce energy consumption. As the UV lamp ages, the model will increase the light intensity compensation to extend the life of the lamp. According to the T10 value of the water, the light intensity and the type of pathogens, the water flow rate in the disinfection box is adjusted to ensure that each unit of water flow undergoes sufficient UV exposure time. When the T10 value is low (for example, poor water quality and weak light transmittance), the model predicts that a slower water flow rate is required to increase the UV exposure time. According to the T10 value and water quality, the model automatically calculates and adjusts the mixing ratio of clean water and wastewater to ensure that the T10 value is maintained in the optimal range. When the T10 value is detected to be too low, the model predicts that more clean water needs to be mixed into the system to increase the UV transmittance of the water.

[0079] The self-learning adjustment algorithm module works based on the closed-loop feedback system in control theory. Each time the equipment parameters are adjusted, the system will re-collect new data and compare it with the predicted value: if the error between the new data and the predicted value is large, the model will further adjust the parameters; if the error is small, the system will maintain the current settings; the module has strong adaptive and self-optimization capabilities, and can make real-time adjustments according to changes in the environment and water quality, significantly improving the intelligence level of the disinfection machine and maximizing energy efficiency while ensuring the disinfection effect.

[0080] See also Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: an energy-saving self-regulating NSTG-UVC disinfection machine for horticulture, wherein the ultraviolet disinfection core module is used to fully disinfect the water flowing through the disinfection box;

[0081] The core module of ultraviolet disinfection includes: ultraviolet lamp, quartz tube and UV box. The ultraviolet lamp is installed inside the quartz tube, and the quartz tube is installed inside the UV box.

[0082] The UV lamp uses a mercury lamp / LED UV lamp, the wavelength is controlled at 200-280 nanometers, and the output power of each lamp tube is 40-150W, which is set according to the size of the disinfection box and the water flow rate. The lamp tube is made of aluminum heat dissipation material;

[0083] The quartz tube is made of quartz glass tube with a UV transmittance of more than 85%. It can maintain high light transmittance when the water does not touch the lamp tube. The surface of the quartz tube adopts super hydrophobic coating technology to reduce dirt adhesion, and is equipped with an automatic descaling device.

[0084] The inner wall of the UV box is made of 316 stainless steel, and the reflection system reaches 90%. The UV box is cylindrical to ensure that the water flow forms uniform turbulence in the box.

[0085] The UV-C box is also designed with a modular filtration and descaling system, which is used to filter water and prevent dirt on the quartz tube from affecting the UV transmittance;

[0086] Modular filtration and descaling systems include: sand filters, self-cleaning filters and automatic descaling devices;

[0087] The sand filter is installed at the water inlet of the UV-C box, with a filtration accuracy of 50um, and is used to remove large suspended particles. The sand filter is equipped with a differential pressure sensor. When the filter is detected to be blocked, the backwash process is automatically started to flush the accumulated particles.

[0088] The self-cleaning filter is installed at the water outlet of the sand filter, with a filtration accuracy of 25um, to ensure that the content of suspended particles in the water entering the UV disinfection box is less than 5mg / L;

[0089] The automatic descaling device uses a weak acid solution to regularly clean the surface of the quartz tube to dissolve the deposits. The acid cleaning time interval is set by the control system;

[0090] Furthermore, the water first passes through the sand filter to remove large suspended particles (>50um) in the water to prevent it from affecting the subsequent fine filtration and ultraviolet penetration. The sand filter is equipped with a differential pressure sensor. When the differential pressure exceeds the standard (indicating that the filter is clogged), the system will automatically trigger the backwash process to remove the particles on the filter and maintain the filtration efficiency. The water continues to enter the self-cleaning filter, which can remove small particles (>25um) in the water to reduce the suspended matter content in the water, making the water clearer and improving the ultraviolet penetration rate. After preliminary filtration, the water flows into the ultraviolet disinfection core module. The module irradiates the water with ultraviolet rays emitted by the UV-C lamp. The intensity of the UV light wave is set in the range of 200-280 nanometers to kill microorganisms and pathogens in the water;

[0091] The surface of the quartz tube is prone to dirt or mineral deposits during long-term use, which affects the UV-C transmittance. The system monitors the transmittance of the quartz tube through a transparency sensor. When the transmittance drops below 80%, the automatic descaling program is started. When the quartz tube detects dirt accumulation, the system starts the pickling mechanism and injects a weak acid solution (such as citric acid or nitric acid) to dissolve the deposits on the surface of the quartz tube. The system uses a built-in wiping device to mechanically clean the dirt on the surface of the quartz tube to ensure thorough cleaning. The wiping action is usually combined with pickling to further ensure light transmittance. After filtration and descaling are completed, the system will re-test the water quality and the transmittance of the quartz tube to ensure that the UV disinfection efficiency returns to normal levels. If it is detected that the water quality still does not meet the standard after filtration, the system will reduce the water flow rate or increase the mixing ratio to automatically adjust the disinfection parameters.

[0092] See also Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: an energy-saving self-adjusting NSTG-UVC disinfector for horticulture, wherein the automatic T10 value detection and adjustment module is used to detect the T10 value of water and automatically adjust the operating parameters of the disinfector;

[0093] The automatic T10 value detection and adjustment module includes: a T10 value sensor, an automatic water mixing valve and a water mixing control algorithm;

[0094] The T10 value sensor uses an ultraviolet light transmission sensor to monitor the transmittance of suspended particles in water to ultraviolet light in real time, with a measurement accuracy within ±1%, ensuring accurate test results.

[0095] The automatic water mixing valve adopts a three-way valve. When the T10 value is lower than the set value, the system automatically opens the water mixing valve to mix the clean water and wastewater in proportion. The mixing ratio is adjusted by the proportional control valve installed on the automatic water mixing valve. The proportional adjustment range is 0-100%, and the maximum mixing flow rate is 5m 3 / h, the control system dynamically adjusts the opening of the mixing valve according to the T10 value sensor data, so that the T10 value is always kept within the set safety range

[0096] The UV elimination box is also equipped with a dynamic flow rate control module, which is used to detect the water flow rate in real time and perform dynamic adjustment;

[0097] The dynamic flow rate control module includes: a flow sensor, an electric water valve and a flow rate control algorithm;

[0098] The flow sensor based on ultrasonic principle is installed at the water inlet of the UV box to monitor the speed of water entering the UV box in real time. The measurement range is 0.5-15m 3 / h, accuracy ±0.5%;

[0099] The electric water valve is installed at the water inlet of the UV box, and receives the disinfection water source from the outside. The valve adopts a proportional adjustment design to ensure that it can respond quickly when the water flow rate suddenly changes;

[0100] The flow rate control algorithm in the control system combines the data from the flow sensor and the light intensity sensor, and the algorithm adjusts the opening of the electric water valve in real time;

[0101] The flow rate control algorithm adopts PID control algorithm, and the flow rate control process is as follows:

[0102] Data collection: real-time collection of water flow rate and ultraviolet light intensity in the UV box;

[0103] Real-time feedback: Real-time feedback of collected data to the control system;

[0104] Algorithm logic: adjust the opening of the electric water valve according to the error value output by the PID control algorithm

[0105] Further, the wastewater flows into the disinfection machine. The T10 value sensor detects that the T10 value of the wastewater is 12% (lower than the set value of 15%). It appears that there are too many suspended solids in the wastewater and the ultraviolet transmittance is low, which affects the disinfection effect. The control system automatically opens the mixing valve and starts to mix clean water, gradually increasing the T10 value to 20%. The opening of the mixing valve is proportionally controlled by the control system to ensure that the water quality is gradually restored. At the same time, the flow sensor detects that the current flow rate is 10m 3 / h. Due to the low T10 value, the control system controls the opening of the electric water valve through the PID control algorithm output to reduce the flow rate to 8m 3 / h, ensuring that each unit of water has sufficient retention and disinfection time in the disinfection box; as the T10 value recovers to 20% and the flow rate is fully adjusted, the disinfection process enters a stable state.

[0106] See also Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: an energy-saving self-regulating NSTG-UVC disinfector for horticulture, wherein the intelligent pathogen identification module is used to detect the type of pathogens in water and automatically select the appropriate UV-C dosage;

[0107] The intelligent pathogen identification module includes: pathogen sensor, automatic dose adjuster and pathogen database;

[0108] The pathogen sensor is installed in the UV box. The pathogen sensor uses spectral analysis technology to detect the type of pathogen by analyzing the microbial components in the water. It can also detect the concentration of pathogens in the water. The concentration detection range is 10 3 -10 6 CFU / ml;

[0109] The automatic dose adjuster automatically calculates the required UV-C dose based on the pathogen concentration and type fed back by the pathogen sensor. When the pathogen sensor detects a change in pathogen concentration, the control system can send a signal through the automatic dose adjuster to adjust the UV lamp dose in real time.

[0110] The control system has a built-in pathogen database that covers the disinfection dosage requirements of common pathogens. The database is updated regularly to support users to import new pathogen data as needed.

[0111] The light intensity automatic adjustment module is used to automatically adjust the output light intensity of the UV-C lamp according to the aging condition of the ultraviolet lamp, the ambient light intensity and the water quality conditions;

[0112] The light intensity automatic adjustment module includes: light intensity sensor, light intensity regulator and aging compensation mechanism;

[0113] The light intensity sensor uses an ultraviolet radiation intensity sensor, which is installed on the side of the inner wall of the UV box to monitor the radiation intensity of the ultraviolet lamp in real time. The monitoring range is 0-500mj / cm 2 , with an accuracy of ±2%. The light intensity sensor combines with the working market of the ultraviolet lamp to automatically detect the degree of lamp aging and prompt lamp replacement based on the attenuation of radiation intensity;

[0114] The light intensity regulator adopts PWM control, which controls the current supply of the UV lamp through PWM technology, adjusts the light intensity output, and ensures that the light intensity is automatically adjusted to the optimal level when the light ages / water quality changes. The adjustment range is 60-100% light intensity output. The control system can automatically select three levels of light intensity output mode according to water quality and pathogen type;

[0115] The aging compensation mechanism is that the control system is designed with an automatic compensation algorithm. As the UV lamp ages, the light intensity decays. The control system increases the current supply through the automatic compensation algorithm to slow down the rate of light intensity decay.

[0116] Furthermore, the pathogen sensor samples water in real time and uses spectral analysis technology to identify the type and concentration of pathogens in the water. It can identify common bacteria, fungi, nematodes and viruses. The control system compares the detected pathogen information with the standard data in the internal database to identify the UV disinfection dosage requirements of the corresponding pathogens. For example, for fungi, molds and bacteria, the system sets the minimum UV-C dosage to 60 mJ / cm²; for viruses such as tomato mosaic virus, the UV-C dosage is set to 150-250 mJ / cm². According to the type and concentration of the pathogen, the system automatically calculates the current required UV dosage. The pathogen identification module transmits the calculated disinfection dosage information to the light intensity automatic adjustment module through the controller, instructing the latter to adjust the light intensity output of the UV lamp.

[0117] The light intensity sensor monitors the current light intensity of the UV lamp. If the light intensity is insufficient, the system will immediately adjust the power of the lamp. The light intensity automatic adjustment module changes the current and voltage of the lamp through the PWM controller. The PWM control technology can accurately control the output power of the lamp, so that the light intensity can change dynamically within the range of 60%-100%, ensuring that the disinfection dose meets the actual needs. When the pathogen concentration is high, the system sets the light intensity to 100% to ensure that each unit of water flow receives sufficient ultraviolet radiation. When the pathogen concentration is low, the system reduces the light intensity to 60%-80%, which not only ensures the disinfection effect, but also saves energy. As the UV lamp is used for a longer time, the light intensity of the lamp will gradually decay. The light intensity automatic adjustment module automatically increases the current supply of the lamp through the aging compensation mechanism, slows down the rate of light intensity decay, and ensures that the UV-C output meets the disinfection requirements.

[0118] See also Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: an energy-saving self-regulating NSTG-UVC disinfector for horticulture, wherein an energy recovery system is also installed in the disinfector, and the energy recovery system is used to recover the excess heat generated when the ultraviolet lamp is working;

[0119] The energy recovery system includes: heat exchanger, temperature sensor and heat transfer system;

[0120] A plate heat exchanger and cooling fins are installed on the outer wall of the UV box. The heat exchanger is made of 316 stainless steel.

[0121] The temperature sensor is installed on the outer wall of the UV box. The temperature sensor detects the temperature of the UV box in real time. When the temperature is higher than 60℃, the heat recovery device is automatically started to transfer excess heat to other systems.

[0122] The heat transfer system uses PPR pipes to connect the heat exchanger and the greenhouse heating system to provide heat for the horticultural greenhouse;

[0123] Furthermore, when the ultraviolet disinfection system in the greenhouse starts to operate, the UV lamp generates a large amount of waste heat through continuous work, causing the temperature in the disinfection box to gradually rise to 65°C. The temperature sensor detects that the temperature in the disinfection box exceeds 60°C, and the control system automatically starts the heat exchanger to capture the waste heat generated by the ultraviolet lamp. The heat exchanger transfers the captured heat to the heat recovery pump through the heat transfer medium, and the heat is then transported to the greenhouse heating system through the high-efficiency PPR pipe. The recovered heat is transported to the greenhouse heating system to assist in heating the air or water in the greenhouse, thereby reducing the heating energy consumption of the greenhouse. When the internal temperature of the greenhouse reaches the preset value, the control system detects that no further heating is needed, automatically shuts down the heat recovery pump, stops heat transmission, and enters standby mode.

[0124] Working principle: When water enters the UV box, it first passes through the sand filter and the self-cleaning filter to remove large particles and tiny suspended solids respectively. The filtered water enters the UV disinfection core module, and the UV-C lamp emits ultraviolet light with a wavelength of 200-280 nanometers to destroy the DNA or RNA of pathogens in the water and kill bacteria, fungi, viruses and other microorganisms;

[0125] Then, the automatic T10 value detection and adjustment module detects the UV transmittance (T10 value) of the water in real time. If the T10 value is too low, the system will automatically adjust the water mixing ratio to improve the water's light transmittance. At the same time, the dynamic flow rate control module adjusts the water flow rate according to the water quality and disinfection requirements to ensure that the water stays in the disinfection box for a sufficient amount of time to receive sufficient UV radiation. In addition, the intelligent pathogen identification module detects the type and concentration of pathogens in the water in real time, and adjusts the intensity of the UV lamp according to the characteristics of the pathogens to ensure that the disinfection dose is accurate and effective;

[0126] Finally, the waste heat generated during the UV disinfection process is captured by the energy recovery system and used for other energy needs, such as greenhouse heating. The heat exchanger captures the heat generated by the UV lamp, the temperature sensor monitors the temperature change of the disinfection box, and the heat recovery pump transfers the heat to the external equipment to achieve efficient reuse of energy. The entire system continuously optimizes the water treatment, disinfection and energy utilization processes through automatic control and feedback mechanisms to ensure efficient operation of the equipment and save energy.
