Description

Technical Field

[0001] The invention relates to the technical field of controlling the temperature of parallel reactors, and discloses a multi-channel parallel reactor based on photoelectric integration. Background Art

[0002] At present, the traditional photoreactor on the market is a multi-channel parallel reactor, which can perform multi-channel synchronous reaction of light irradiation while operating with a magnetic stirrer. However, there are many defects, such as complex design and high price, cumbersome operation and waste of scientific research time. In addition, different heat dissipation methods will also affect the reaction temperature. In the prior art, fans are mainly used, and assembly accessories such as heat insulation boards and heat sinks are matched to perform heat dissipation cooling. The heat dissipation cooling of this method cannot quickly and effectively remove the generated heat, but will cause temperature fluctuations. Such temperature fluctuations may have a negative impact on the control of photochemical reactions. For example, reactions under certain low temperature conditions require stricter temperature control, and the fan condensation method is relatively less stable than liquid refrigerants. In addition, due to the lack of control function of the wavelength power of each parallel reaction channel light source in the photoreactor on the market, the selectivity of the reaction is limited, resulting in an increase in the production of undesirable products and a decrease in reaction efficiency, and it is also difficult to maintain the stability of the reaction at a specific temperature. In addition, most photoreactors on the market do not have a reaction time setting function during the experiment, which makes it difficult to accurately control the duration of the reaction, affecting the yield and selectivity of the product. Some products still need to be carried out within a certain time range. When the reaction time cannot be controlled, it will lead to product instability and the occurrence of side reactions.

[0003] For example, the existing Chinese patent with publication number CN100487428C discloses a device for rapid screening of catalysts by multi-channel ultraviolet absorption method. The whole device is mainly composed of a deuterium lamp, a convex lens, a chopper, an aperture, a monochromator, a photomultiplier tube, a high-voltage power supply, a lock-in amplifier, a computer, a multi-channel absorption cell, a one-dimensional displacement and a lifting platform, and a polytetrafluoroethylene tube connecting the reactor and the multi-channel absorption cell. The invention adopts a self-designed multi-channel parallel reactor, and the detection method adopted is ultraviolet absorption spectroscopy detection. The multi-channel absorption cell is placed side by side on the one-dimensional displacement and lifting platform, which strengthens the automation of the ultraviolet absorption detection method and speeds up the data acquisition speed. This device can evaluate catalyst samples in parallel with high throughput, with high speed and high efficiency.

[0004] However, the above patent has the following problems: lack of temperature control. If the temperature distribution in different channels or reactors in the device is uneven, it may lead to inconsistent catalyst activity and reaction rate, thereby affecting the accuracy of the screening results. If the heat generated during the reaction is not removed in time, it may cause the equipment to overheat, affecting the performance of the catalyst and the stability of the equipment.

The temperature sensor must be accurate and responsive to ensure real-time performance and accuracy, and is used to monitor and record the temperature of each reaction channel in real time. The temperature sensor is arranged in each reaction channel, and the collected data is transmitted to the data processing unit through the data acquisition interface. The signal converter converts the analog signal of the temperature sensor into a digital signal for subsequent processing.

[0025] Furthermore, the data processing unit includes a data filter, a calibration algorithm and a data storage unit. The data filter is used to clean up abnormal data and noise, the calibration algorithm is used to calibrate the temperature sensor reading to ensure data accuracy; the data storage unit stores the processed data; The data processing unit is used to process the collected temperature data to remove noise, correct errors and perform data preprocessing.

[0026] The data processing unit processes the raw temperature data through a filtering algorithm and calibrates it according to a preset calibration curve, and finally generates a data set for analysis.

[0027] like Figure 2 As shown, the data module collects temperature data, cleans abnormal data and noise from the temperature data through data preprocessing, establishes a data set with the preprocessed temperature data, extracts the characteristic values ​​of the data set, establishes a characteristic attribute set, establishes a temperature monitoring model through the characteristic attribute set, monitors and predicts the working temperature of the multi-channel parallel reactor in real time, evaluates and optimizes the prediction result of the temperature monitoring model through the evaluation function, if the prediction result is good, the temperature of the multi-channel parallel reactor is controlled, if the prediction result is poor, the temperature monitoring model is optimized; Furthermore, the data analysis unit is used to extract features and analyze the processed temperature data and establish a label set for further research and application.

[0028] The operating temperature data of the multi-channel parallel reactor is extracted by a feature extraction algorithm, which is used to extract key features from the temperature data, such as the mean value, fluctuation amplitude, etc.

[0029] The covariance matrix of the data set is calculated, and the correlation between the working state and the working temperature of the multi-channel parallel reactor is calculated through correlation. The working temperature data of the multi-channel parallel reactor is extracted and calculated. The feature extraction expression is as follows: ; in, is the working state of the multi-channel parallel reactor at the i-th moment, is the temperature data corresponding to the multi-channel parallel reactor in the working state at the i-th moment, cov(·) is the function for finding the covariance, var(·) is the function for finding the variance, S i is the temperature data characteristic value of the multi-channel parallel reactor under the working state at the i-th moment; Specifically, the working state of the multi-channel parallel reactor at the i-th moment is Including different adjustable light source wavelength power and reaction time. By controlling the light source wavelength power and light source output power time, the working state of the multi-channel parallel reactor is determined. For example, channel 1: the light source is set to a wavelength of 400nm and a power of 30W to provide sufficient energy to stimulate the reaction. The reaction time is set to 60 minutes. During these 60 minutes, the light source continues to output a power of 30W to ensure that the reaction proceeds stably.

[0030] Channel 2: Adjust the wavelength of the light source to 500nm, set the power to 20W, use weaker light energy for the reaction, set the reaction time to 120 minutes, allow the reaction to be irradiated with a 500nm, 20W light source for a longer period of time, and observe the progress of the reaction and the formation of products.

[0031] Channel 3: Set the light source power to a lower 15W, the wavelength to 350nm, and the reaction time to 90 minutes. During this period, the light source stably outputs 15W of 350nm light to explore the reaction effect under this condition. In this way, the light source wavelength, power, and light source output power time (i.e., reaction time) of different channels of the multi-channel parallel reactor are regulated at the i-th moment.

[0032] Furthermore, the covariance function calculation expression is as follows: ; in, is the rated working state of the multi-channel parallel reactor, is the temperature data of the multi-channel parallel reactor under rated working conditions, and n is the time series; Rated operating conditions of multi-channel parallel reactors Output the rated light source wavelength power for the parallel reactor, wherein the rated light source wavelength power can be a specific value or a rated range, which is set according to the actual application scenario and production requirements of the multi-channel parallel reactor. For example, through the control interface of the multi-channel parallel reactor, set specific light source wavelengths and powers for different channels, channel 1 sets the wavelength to 380nm and the power to 15W; channel 2 sets the wavelength to 420nm and the power to 20W; channel 3 sets the wavelength to 450nm and the power to 25W, etc. All settings are within the rated wavelength and power range, start the multi-channel parallel reactor, the light source outputs light according to the set wavelength and power, and the temperature control system starts working at the same time, and the hydrogen production in each channel is monitored in real time. After 2 hours of reaction, the amount of hydrogen collected in each channel is analyzed and compared, and the hydrogen production performance of different photocatalysts under different lighting conditions is evaluated. According to the results, the lighting conditions are adjusted, and a new round of experiments are carried out within the rated working state range to gradually optimize the photocatalytic hydrogen production process.

[0033] The data analysis unit applies statistical and machine learning algorithms to conduct in-depth analysis of temperature data, extract key temperature features of reaction channels, and create labels based on these features, such as "optimal reaction conditions" or "temperature anomaly."

[0034] The tag set is used to count the characteristic attribute set of the temperature under different working states at different times based on the optoelectronic integrated multi-channel parallel reactor; ; in, is the characteristic attribute set of the temperature of the multi-channel parallel reactor under different working conditions at different times in period j, is the first time working temperature characteristic value of the multi-channel parallel reactor, is the first time working temperature value of the multi-channel parallel reactor, S n is the characteristic value of the operating temperature of the multi-channel parallel reactor at the nth time, is the operating temperature value of the parallel reactor at the nth time; the first time and the nth time are set by those skilled in the art according to actual conditions.

[0035] By intercepting the working temperature characteristic values ​​and working temperature value sets of the multi-channel parallel reactor in 1~n time periods, the characteristic attribute set can be retrieved more quickly, and the temperature control efficiency of the multi-channel parallel reactor based on optoelectronic integration can be enhanced. According to the linear characteristics of temperature change, the characteristic attribute set of 1~n time periods can be retrieved, and the characteristic attribute set of j time period can also be retrieved; A monitoring module, including a temperature monitoring unit, a temperature evaluation unit and a temperature feedback unit; The temperature monitoring unit is used to receive the tag set and establish a temperature monitoring model to monitor and predict the temperature of the multi-channel parallel reactor. The temperature evaluation unit is used to analyze and evaluate the working temperature of the multi-channel parallel reactor. The temperature feedback unit is used to feed back the temperature of the multi-channel parallel reactor to the control module. The temperature monitoring model calculation expression is as follows: ; in, The temperature prediction value output by the temperature monitoring model of the multi-channel parallel reactor, is the temperature weight at the i-th moment, is the characteristic attribute set of the i-th period, is the deviation value, f(·) is the activation function, and k is the total temperature monitoring time; The activation function here is a conventional activation function; Set the minimum threshold and maximum threshold of the characteristic value of the multi-channel parallel reactor. If the minimum threshold of the characteristic value of the multi-channel parallel reactor is greater than the characteristic value of the temperature data of the multi-channel parallel reactor, increase the temperature weight. If the characteristic value of the temperature data of the multi-channel parallel reactor is greater than the minimum threshold of the characteristic value and less than the maximum threshold of the characteristic value, adjust the weight by the mean. If the characteristic value of the temperature data of the multi-channel parallel reactor is greater than the maximum threshold of the characteristic value, reduce the weight. The weight optimization calculation expression is as follows: ; in, is the weight optimization coefficient, is the minimum threshold of the eigenvalue at the i-th moment, is the maximum threshold of the eigenvalue at the i-th moment, is the maximum threshold of temperature weight at the i-th moment, is the minimum threshold of temperature weight at the i-th moment; In the above formula, 1 means increasing the weight, and 0 means decreasing the weight; The operating temperature of the multi-channel parallel reactor is evaluated by an evaluation function. The evaluation function includes a decision value. If the decision value is close to 1, it means that the operating temperature of the multi-channel parallel reactor is better, the predicted temperature is more accurate, and the control module controls the temperature of the multi-channel parallel reactor more accurately. The evaluation function expression is as follows: ; in, is the decision value, is the actual temperature value of the multi-channel parallel reactor in the jth period, is the average temperature of the multi-channel parallel reactor in the jth period, The temperature value predicted by the temperature monitoring model of the multi-channel parallel reactor for the jth period, m is the total time; A control module, including a control command unit, an inner loop control unit and an emergency control unit; The control command unit is used to receive the feedback of the multi-channel parallel reactor temperature and generate a control command, the inner circulation control unit receives the control command to improve the inner circulation heat dissipation, and the emergency control unit is used to perform emergency stop and heat dissipation for the multi-channel parallel reactor temperature failure; Among them, the control instruction unit is used to receive data output from the temperature monitoring model, analyze the current temperature state of the multi-channel parallel reactor, and generate corresponding control instructions based on temperature feedback to adjust the operating parameters of the multi-channel parallel reactor.

If the temperature is too low, the output is to weaken the internal circulation heat dissipation instruction. The internal circulation control unit is used to receive the internal circulation heat dissipation instruction, and then control the internal circulation efficiency of the multi-channel parallel reactor; The emergency control unit monitors the temperature anomalies of the multi-channel parallel reactor.
