Description

Technical Field

[0001] This invention relates to the field of solar energy utilization technology, and in particular to a solar energy intelligent dynamic adjustment system and method based on a photothermal coupling reaction device. Background Technology

[0002] Photothermal coupling technology has seen widespread application in the energy, chemical, and environmental protection fields in recent years, including waste disposal, hydrogen production, pollutant treatment, and fine chemical synthesis. The photothermal coupling reaction device optimizes the synergistic effect of light and heat energy, effectively reducing the activation energy and accelerating the reaction process, thereby significantly improving reaction efficiency and effectiveness. The importance of the photochemical reaction section in the photothermal coupling device is self-evident; it is not only a key link in the energy conversion and utilization of the entire system but also directly affects reaction efficiency, product selectivity, and system stability. By adjusting parameters such as light intensity and wavelength, the reaction process can be precisely controlled, improving the yield and purity of the target product. Currently, the main methods for adjusting photochemical reaction parameters include adjusting the power and focusing degree of the light source, using a light shield, aperture, and the relative position between the light source and the reaction system to adjust the light intensity, and using techniques such as filters, monochromatic light sources, or LED light sources to adjust the light wavelength.

[0003] However, in practical applications, on the one hand, accurate measurement of light intensity can optimize reaction conditions, improve reaction rates and product selectivity, and help evaluate the performance and efficiency of the device. Currently, in photothermal coupling equipment, light intensity measurement mostly relies on external devices to the reactor, making it difficult to measure the light intensity inside the chamber in real time during the reaction. On the other hand, precise control of light conditions is often affected by various factors, such as the stability of the light source, the transmittance of the reaction system, and fluctuations in ambient temperature. Especially for methods that directly adjust the power of the light source, the limitations of the light source itself and the precision of the adjustment mechanism prevent very fine adjustment of light intensity. Existing solar thermal utilization systems often lack flexibility and intelligent adjustment capabilities for light and temperature, failing to adjust light and temperature according to actual needs, leading to inaccurate control of experimental conditions and energy waste. In the photoreaction process, the functional group structure of the raw materials has a crucial impact on the reaction process and products. However, traditional equipment typically cannot detect the functional group structure of the raw materials in real time, let alone automatically adjust reaction parameters based on the detection results. This necessitates frequent manual intervention during use, which is not only inefficient but also makes it difficult to ensure reaction consistency and product quality. Furthermore, existing technologies lack an intelligent system capable of adjusting the light band and intensity in real time based on the functional groups contained in the raw materials.

[0004] Therefore, there is an urgent need for a solar intelligent dynamic regulation system and method based on a photothermal coupling reaction device to solve the above problems. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1:

[0038] Reference Figures 1-4This invention provides a solar intelligent dynamic regulation system based on a photothermal coupling reaction device, comprising:

[0039] Reactor body 6;

[0040] An intelligent detection module is installed at the inlet of the reactor body 6 to detect the main functional groups of the raw materials entering the reactor body 6.

[0041] The back-end server has a built-in database of raw material composition and light-sensitive wavelengths and intensities, which is used to retrieve the corresponding light-sensitive wavelengths and control parameters based on the detection data.

[0042] The dimming system includes a filter and a dimming element, and has a top viewing window. The filter is located at the top of the reactor body 6, and an external light source enters the reactor body 6 through the filter. The dimming element is installed above the top viewing window to adjust the light intensity entering the reactor body 6, and can automatically adjust the light characteristics according to the parameters provided by the backend server.

[0043] The control system includes a detection element and a control element. The detection element is disposed on the reactor body 6 for monitoring the illumination parameters inside the reactor body 6. The control element is connected to the detection element for controlling the dimming element.

[0044] Specifically, the reaction vessel body 6 is used to place the reaction materials. The sunlight shines into the reaction vessel body 6 through the set filter. The light power density and temperature inside the reaction vessel body 6 are monitored by the set detection device. Then, the set control device controls the set dimming device to adjust the opening and closing angle, thereby realizing the adjustment of the light intensity.

[0045] Specifically, the intelligent detection module preferentially uses Fourier transform infrared spectroscopy. The infrared spectrometer is connected to the backend server for communication testing to ensure normal data transmission. The infrared spectrometer is then activated to detect the functional group structure of the raw material and transmit the data to the backend server. The backend server retrieves the corresponding sensitive light band and control parameters from its database and sends instructions to the light control module. The light control module automatically adjusts the filters and photoresponse parameters according to the instructions. The equipment's operating status is monitored in real time via a remote terminal, and parameters can be manually adjusted if necessary.

[0046] As an optional implementation, the filter includes a light viewing window 4 disposed at the top of the reactor body 6, a filter device 5 fixedly connected inside the light viewing window 4, and a filter sheet detachably connected inside the filter device 5.

[0047] In one embodiment of the present invention, a solar light source is introduced into the reactor body 6 through a light viewing window 4, and the light filtering device 5 can adjust the light band by inserting different filters.

[0048] As an optional implementation, the dimming component includes a louver structure 3, which is mounted on the top of the reactor body 6 by a fixing nut 2 and is located directly above the light viewing window 4.

[0049] In one embodiment of the present invention, the intensity of light entering the filter is adjusted by opening and closing the louver structure 3 at different angles.

[0050] As an optional implementation, the detection element includes an optical fiber sensor 8, the detection end of which extends into the reactor body 6.

[0051] In one embodiment of the present invention, an optical fiber sensor 8 is inserted into the reactor body 6 to monitor the optical power density and temperature inside the reactor body 6.

[0052] As an optional implementation, the control element is either an electronic switch or a PID controller.

[0053] In one embodiment of the present invention, the control component is connected to the fiber optic sensor 8 and the louver structure 3. The fiber optic sensor 8 transmits data signals to the control component, and the control component controls the rotation of the louver structure 3 to adjust its opening and closing angle.

[0054] Specifically, a motor can be selected to drive the 3-axis structure of the louver structure to rotate, thereby adjusting the louver structure 3.

[0055] As an optional implementation, the louver structure 3 can be adjusted from 0° to 90°.

[0056] In one embodiment of the present invention, the light intensity is adjusted by changing the angle of the louver structure 3 to meet different usage scenarios.

[0057] As an optional implementation, the filter can be adjusted in the range of 254nm-940nm.

[0058] In one embodiment of the present invention, different filters are selected to filter sunlight in different ways to meet different application scenarios.

[0059] As an optional implementation, the reactor body 6 is provided with a heat insulation layer 7.

[0060] In one embodiment of the present invention, the interior of the reactor body 6 is insulated by a heat insulation layer 7.

[0061] As an optional implementation, a material holding device 9 is provided at the bottom of the reactor body 6, and a sand plate 10 is provided inside the material holding device 9. A liquid outlet 13 is provided at the bottom of the reactor body 6, and a condensing device 11 is provided on the liquid outlet 13. The condensing device 11 is connected to an external cold source, and an air outlet 12 is connected to the liquid outlet 13. An air inlet 1 is provided at the top of the side wall of the reactor body 6.

[0062] In one embodiment of the present invention, the material holding device 9 is a trough structure for holding materials, and the condensing device 11 is connected to external condensate water for circulating flow to achieve refrigeration.

[0063] A method for intelligent dynamic regulation of sunlight based on a photothermal coupling reaction device includes the following steps:

[0064] Sunlight is directed into the reactor body 6 through a filter;

[0065] The light power density and temperature inside the reactor body 6 are monitored by the set detection devices;

[0066] The opening and closing angle of the dimming component is controlled by the control component, thereby adjusting the light power density and temperature inside the reactor body 6.

[0067] Specifically, the fiber optic sensor 8 is used to monitor and provide real-time feedback on the optical power density and temperature data within the device. Based on intelligent algorithm analysis, machine learning algorithms are used to train and learn from a large amount of historical data to establish a predictive model of the reactor's operating status, including but not limited to artificial neural networks, support vector machines, and random forests. When the sensor detects a high temperature at noon, the required heat for the actual experiment is transferred to the photothermal coupling reactor via an electronic switch / PID controller, with the remainder transferred to the photovoltaic cells. Unused solar energy is converted into electrical energy and stored in the photovoltaic cells. When the optical power density is strong, the opening angle of the louver structure 3 is adjusted via the electronic switch / PID controller to reduce the intensity of light entering the device. When the temperature is lower in the morning and evening, the stored electrical energy is used for electric heating. Simultaneously, an intuitive and easy-to-use visualization interface is embedded, displaying the real-time data detected by the fiber optic sensor 8 in the form of charts, animations, etc., facilitating understanding of the reactor's operating status and remote control.

[0068] Specifically:

[0069] A heating rate of 1℃ / min was selected to raise the temperature from 30℃ to 500℃, with an optical power density of 100Wm. -2A simultaneous coupled experiment of photo-oxidation and slow pyrolysis under certain conditions was conducted. Without inserting a filter, the experiment used full-spectrum sunlight irradiation from 8:00 AM to 4:00 PM. From 8:00 AM to 10:00 AM, when the initial temperature was low, all electrical energy (converted from the previous day's solar energy) was provided by the photovoltaic cells for electric heating. At this time, the solar power density provided was sufficient for the experiment. From 10:00 AM to 12:00 PM, the sun provided all the heat, and excess heat was distributed to the photovoltaic cells for conversion into electrical energy. At this time, the solar power density was too high, so the opening angle of the louver structure 3 was adjusted according to the solar power density measured by the sensor to ensure that the solar power density was maintained at 100 W / m². -2 From 12:00 to 16:00, the heat provided by solar energy was insufficient, so photovoltaic cells were used for electric heating to supplement it. Similarly, the opening and closing angle of the louver structure 3 was adjusted according to actual needs. All of the above processes were automatically adjusted and converted by a PID controller and electronic switches, resulting in a liquid phase product yield of 60% and a mass recovery rate of 48%.

[0070] Selected solar full-spectrum irradiation at 210℃, with a light power density of 550Wm. -2 Under certain conditions, a simultaneous coupled photo-oxidation-rapid pyrolysis experiment was conducted without the insertion of filters, using full-spectrum sunlight irradiation. From 10:00 AM to 12:00 PM, the temperature inside the reactor could reach 420℃, and the light power density could reach 600 W / m². -2 When the reaction temperature is only 210℃ and the light power density is 550Wm -2 At room temperature (30℃), the opening and closing angle of the louvers was adjusted so that 50% of the light was directed into the solar photovoltaic panel, and the other 50% was directed into the solar photovoltaic panel to convert the light into electrical energy stored in the photovoltaic cells. The results showed that the liquid phase product yield was 21% and the mass recovery rate was 18.9%.

[0071] The selected method was a stepwise coupled experiment of photo-oxidation and rapid pyrolysis. The photo-oxidation reaction conditions were 365 nm and 100 W / m². -2 The rapid pyrolysis conditions were 500℃ for 30 minutes, with an initial exposure of 30℃ for 4 hours. From 8:00 to 12:00, a photo-oxidation reaction was carried out using a 365nm filter. Based on the real-time feedback of light power density and temperature from the sensor, the incident light ratio and the opening angle of the louver structure were adjusted. From 12:00 to 12:30, rapid pyrolysis was performed at 500℃, supplemented by electric heating using the electrical energy stored in the daytime photovoltaic cells. The results showed a liquid phase product yield of 83% and a mass recovery rate of 74.7%.

[0072] Example 2:

[0073] Reference Figure 5Different thicknesses of light-transmitting components have different transmittance. For experiments that require precise control over photochemical reaction conditions (such as light power density under different light bands), obtaining the corresponding reaction conditions by adjusting the angle of the louver structure 3 step by step requires a large number of experiments, which is very difficult and troublesome.

[0074] By using machine learning algorithms to train on a large amount of existing data, with the reaction parameters as input and the adjustment angle of the louver structure 3 as output, the angle of the louver structure 3 can be quickly and effectively adjusted according to the reaction requirements.

[0075] Specifically, it includes the following processes:

[0076] Data collection: Collect product yields and raw material recovery rates obtained under different experimental conditions, including but not limited to the ratio of input light and heat energy, reaction temperature, reaction time, light irradiation band, and light power density.

[0077] Data preprocessing includes data cleaning, handling missing values, and handling outliers.

[0078] Feature selection: Selecting and constructing features needed for model training, which may include feature selection, feature extraction, feature transformation, etc.

[0079] Model design, taking artificial neural networks as an example: design the structure of the neural network, including the number of layers, the number of neurons, activation functions, etc. The ratio of the training set to the test set is 3:1 or 4:1.

[0080] Model training: Training the model using the training dataset.

[0081] Model validation: Evaluate the model's performance using a validation dataset.

[0082] Model performance is satisfactory: Use R2 or RMSE to evaluate whether the model's performance meets expectations.

[0083] Model Deployment: If the model performance is satisfactory, deploy the model to the production environment.

[0084] Model tuning: If the model performance is unsatisfactory, model tuning may be performed, which may include adjusting the model structure, optimizing hyperparameters, etc.

[0085] Model prediction: Using a trained model to predict new data.

[0086] Result evaluation: Evaluate the results of the model's predictions.

[0087] Results met expectations: Assess whether the predicted results met expectations.

[0088] End: If the result meets expectations, the process ends; otherwise, return to the model tuning step.

[0089] Example 3:

[0090] Reference Figures 6-7 In this embodiment, a groove 14 is provided on the reactor body 6 for inserting the filter device 5. One end of the groove 14 is connected to the top plate 16 by a spring 15. A buckle plate 17 is provided on the other side of the groove 14. Insert blocks 18 are fixedly connected to both ends of the buckle plate 17. A slot 19 adapted to the insert block 18 is provided on the reactor body 6.

[0091] The filter device 5 installed in the groove 14 is fastened to the reaction vessel body 6 by the set buckle 17, so that different filter devices 5 can be replaced without touching the louver structure 3 and without changing the angle of the louver structure 3, thereby improving the overall test efficiency.

[0092] Specifically, a locking block 20 is fixedly connected inside the slot 19, and a buckle 21 is fixedly connected to the insert block 18. The buckle 21 is adapted to the locking block 20 to ensure the stability of the buckle plate 17 after it is fastened.

[0093] The specific buckle 21 is made of elastic metal.

[0094] The specific groove 14 is semi-circular.
