Description

Technical Field

[0001] This invention relates to the fields of microwave sterilization technology and renewable energy utilization technology. Specifically, this invention relates to a dynamic control method for a microwave sterilization system based on distributed photovoltaic drive. Background Technology

[0002] With increasing environmental awareness, the biomass product industry is undergoing a transformation from chemical processing to biotechnology. In the production of biomass products containing active microorganisms (such as microbial activated cat litter and agricultural biological agents), sterilization is typically required to control the growth of contaminating microorganisms while ensuring the activity of the encapsulated microorganisms. Existing sterilization technologies have the following main drawbacks: First, the issue of energy consumption and carbon emissions.

[0003] Traditional production lines are often equipped with high-power microwave sterilization or drying equipment, which typically operate at constant power, resulting in huge energy consumption and increased carbon emissions. If renewable energy sources such as distributed photovoltaic power generation are used for power supply, the intermittent and fluctuating nature of photovoltaic power generation often necessitates drawing power from the grid or curtailing solar power to ensure stable production, making it impossible to maximize the use of green electricity and truly achieve zero-carbon production.

[0004] Second, it is difficult to balance the bactericidal effect with the microbial activity.

[0005] Microwave sterilization systems require a certain energy input to ensure sterilization effectiveness; however, excessively high energy input may damage the activity of encapsulated microorganisms, while insufficient energy input will fail to meet sterilization requirements. Current technologies struggle to dynamically adjust energy input based on supply conditions, leading to inconsistent product quality.

[0006] Third, the utilization rate of renewable energy is low.

[0007] Distributed photovoltaic power generation on factory rooftops is intermittent and volatile. Existing production lines often use grid connection or energy storage to smooth out these fluctuations, failing to achieve dynamic matching between photovoltaic power and production equipment, resulting in low utilization of "green electricity" and high production costs.

[0008] In summary, there is an urgent need for a technical solution that can combine the energy demand for sterilization with the dynamic regulation of green energy, so as to achieve efficient utilization of photovoltaic power, ensure sterilization effect and microbial activity, and produce high-quality biomass products with active biodegradation function.

Detailed Implementation

[0025] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0026] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0027] The data acquisition process involved in this invention follows the principles of legality, legitimacy, and necessity. Based on obtaining the explicit authorization and consent of the user, only the minimum necessary information required to achieve the purpose is collected, and data security protection obligations are fulfilled in accordance with the law.

[0028] The solution provided in this invention can be applied to any application scenario that requires dynamic control of a microwave sterilization system based on distributed photovoltaic drive.

[0029] This invention provides a possible implementation, such as... Figure 1 The diagram shows a flowchart of a dynamic control method for a microwave sterilization system based on distributed photovoltaic drive. This method can be executed by any electronic device, such as an intelligent control unit built into the microwave sterilization system. For ease of description, the method provided in this embodiment will be described below using the intelligent control unit as the execution subject. Figure 1 The flowchart shown indicates that the method may include the following steps: S10, Obtain the real-time power generation of the distributed photovoltaic power generation unit that powers the microwave sterilization system; S20, dynamically calculates the target operating parameters of the microwave sterilization system based on the real-time power generation and the preset sterilization energy requirements. The target operating parameters include the target microwave power and / or the target material processing time. S30, adjust the current operating parameters of the microwave sterilization system according to the target operating parameters so that the microwave energy supply rate of the microwave sterilization system matches the real-time power generation. The current operating parameters include the current microwave power and / or the current material processing time. The microwave energy supply rate is the microwave energy input to the material by the microwave sterilization system per unit time.

[0030] The method of this invention obtains the real-time power generation of the distributed photovoltaic power generation unit that powers the microwave sterilization system, and dynamically calculates target operating parameters, including target microwave power and / or target material processing time, based on the real-time power generation and preset sterilization energy requirements. Then, it adjusts the current operating parameters, including the current microwave power and / or current material processing time, based on the target operating parameters, so that the microwave energy input to the material by the microwave sterilization system per unit time matches the real-time power of the photovoltaic power generation. This achieves a dynamic balance between the energy consumption and photovoltaic output of the microwave sterilization system, maximizing the utilization of green electricity while ensuring the stability and effectiveness of the sterilization process.

[0031] The following specific embodiments further illustrate the solution of the present invention. In this embodiment, the dynamic control method for a microwave sterilization system based on distributed photovoltaic drive may include the following steps: S10, Obtain the real-time power generation of the distributed photovoltaic power generation unit that powers the microwave sterilization system; In this step, distributed photovoltaic (PV) power generation units are installed on the roof of the factory (a factory producing biomass products containing live microorganisms). These units include PV modules, inverters, and smart meters, used to collect real-time PV power generation data. The smart meters upload the real-time power generation P_PV(t) to the PLC controller of the intelligent control unit via communication protocols such as Modbus TCP, providing basic data for subsequent dynamic control. Real-time power generation refers to the actual output power of the distributed PV power generation unit at the current moment, exhibiting intermittent and fluctuating characteristics.

[0032] Among them, the microwave sterilization system refers to a tunnel-type microwave processing device used to sterilize the final product after the embedding carrier is mixed with the substrate of biomass products (such as cat litter) containing active microorganisms. The microwave sterilization system is equipped with a power controller and the microwave power is adjustable. By penetrating the material through microwave energy, the final product is sterilized, the growth of miscellaneous bacteria is controlled, and the survival of the embedded microorganisms is ensured.

[0033] S20, dynamically calculates the target operating parameters of the microwave sterilization system based on the real-time power generation and the preset sterilization energy requirements. The target operating parameters include the target microwave power and / or the target material processing time. In this step, the intelligent control unit dynamically calculates the target operating parameters of the microwave sterilization system based on the collected real-time power generation and the preset sterilization energy requirements using a built-in algorithm.

[0034] Optionally, in S20 above, the target operating parameters of the microwave sterilization system are dynamically calculated based on the real-time power generation and the preset sterilization energy requirement, including: S201, Determine the energy density threshold range required for sterilization based on the material characteristics. The energy density threshold range includes the minimum energy density threshold and the maximum energy density threshold. Optionally, if the aforementioned material characteristics include the moisture content and microbial content of the material entering the microwave sterilization system, then one implementation of S201 is as follows: Based on the moisture content, microbial content, and target microbial kill rate of the material entering the microwave sterilization system, determine the minimum energy density threshold and the maximum energy density threshold required for sterilization. The minimum energy density threshold D_min is the minimum energy density required to ensure sterilization effectiveness; below this threshold, sterilization is insufficient. The maximum energy density threshold D_max is the maximum energy density required to ensure microbial survival; above this threshold, the activity of the encapsulated microorganisms may be damaged.

[0035] S202, Calculate the required microwave power based on the current batch material quality and the preset energy density setting value determined from the energy density threshold range; Based on the current batch material mass M and the preset energy density setpoint D_set selected between the lowest and highest energy density thresholds, the required microwave power P_req is calculated using the formula: P_req = D_set × M / T_proc, where T_proc is the standard processing time. The preset energy density setpoint D_set is determined based on the material's moisture content, microbial content, and the target bacteria kill rate, ensuring that the preset energy density setpoint satisfies both the sterilization effect and the microbial survival rate.

[0036] The standard processing time refers to the baseline processing time required to sterilize the current batch of materials with the required microwave power, provided that the preset energy density setting value is met. The required microwave power is calculated based on the preset energy density setting value and the mass of the current batch of materials. The standard processing time is determined by dividing the mass of the current batch of materials by the material flow rate.

[0037] S203 compares the required microwave power with the real-time power generation and determines the target operating parameters based on the comparison results.

[0038] Alternatively, one implementation of S203 above is as follows: S2031, if the real-time power generation is greater than or equal to the required microwave power, the required microwave power is determined as the target microwave power and the standard processing time is determined as the target material processing time. If the real-time power generation is greater than or equal to the required microwave power, it indicates that the photovoltaic power is sufficient. At this time, the microwave sterilization system operates at the required microwave power, and the remaining photovoltaic power is connected to the grid or supplied to other loads.

[0039] S2032, if the real-time power generation is less than the required microwave power, determine the real-time power generation as the target microwave power, and determine the extended processing time based on the preset energy density setting value, the current batch material quality and the real-time power generation, and use the extended processing time as the target material processing time.

[0040] Optionally, in the above S2032, one way to determine the extended processing time based on the preset energy density setting, the current batch material quality, and the real-time power generation is as follows: S20321, Calculate the total sterilization energy required based on the preset energy density setting value and the current batch material mass; The total sterilization energy required is E_need = D_set × M, where D_set is the preset energy density setting value and M is the mass of the current batch of materials.

[0041] S20322, based on the total required sterilization energy and real-time power generation, calculates the extended processing time.

[0042] The extended processing time is calculated as T_adj = E_need / P_PV = (D_set×M) / P_PV, where P_PV is the real-time power generation. The extended processing time is greater than the standard processing time, ensuring that the total sterilization energy received per unit mass of material remains consistent with that obtained using the required microwave power and standard processing time.

[0043] S30, adjust the current operating parameters of the microwave sterilization system according to the target operating parameters so that the microwave energy supply rate of the microwave sterilization system matches the real-time power generation. The current operating parameters include the current microwave power and / or the current material processing time. The microwave energy supply rate is the microwave energy input to the material by the microwave sterilization system per unit time.

[0044] In this step, the intelligent control unit can dynamically adjust the microwave sterilization system through the actuator based on the target operating parameters calculated in S20, so that the microwave energy supply rate is matched with the real-time power generation of the distributed photovoltaic power generation unit, thereby realizing the local consumption of photovoltaic power.

[0045] Furthermore, in the above S30, one way to adjust the current operating parameters of the microwave sterilization system according to the target operating parameters is as follows: S301, If ​​the target operating parameters include the target microwave power, then adjust the operating parameters of the microwave power generator of the microwave sterilization system to adjust the current microwave power to the target microwave power. The operating parameters include the anode voltage and / or duty cycle. By adjusting the magnetron anode voltage or duty cycle, the microwave output power can be changed to achieve the target microwave power.

[0046] S302, if the target operating parameters include the target material processing time, then adjust the operating speed of the material conveying device of the microwave sterilization system to adjust the current material processing time to the target material processing time. The operating speed includes the conveyor belt speed.

[0047] By adjusting the conveyor belt speed, the residence time of the material in the microwave field is changed, thus enabling the current material processing time to reach the target processing time. Decreasing the conveyor belt speed increases the processing time, while increasing the conveyor belt speed shortens the processing time.

[0048] Optionally, the method further includes: Obtain the current material flow rate of the material entering the microwave sterilization system; wherein, the material flow rate Q(t) entering the tunnel microwave sterilization system can be monitored in real time by a material flow sensor.

[0049] The current energy density value is calculated based on the current material flow rate and real-time power generation; the current energy density value D_curr is calculated based on the current material flow rate and real-time power generation, reflecting the actual microwave energy received per unit mass of material.

[0050] Determine whether the current energy density value is between the minimum energy density threshold and the maximum energy density threshold; If the current energy density value is lower than the minimum energy density threshold, power will be supplemented from the energy storage unit or the grid to bring the actual energy density after the power supplementation to the minimum energy density threshold. In particular, when the photovoltaic power is too low and the sterilization energy is insufficient, a small amount of power will be automatically supplemented from the energy storage unit or the grid to ensure the sterilization effect and ensure stable product quality.

[0051] If the current energy density value is higher than the maximum energy density threshold, the microwave power of the microwave sterilization system will be reduced or a backup load will be activated to bring the adjusted actual energy density down below the maximum energy density threshold. Specifically, if excessive photovoltaic power may damage microorganisms, the microwave power will be reduced or a backup load (such as a water heater) will be activated to protect the equipment and maintain microbial activity, avoiding over-sterilization.

[0052] By repeating the above steps, this invention enables microwave power to follow changes in photovoltaic power generation while ensuring sterilization effect, maximizing the use of green electricity, reducing carbon emissions from production, and meeting the access requirements for low-carbon products in the Middle East and European and American markets.

[0053] The solution of the present invention has the following beneficial effects: First, it enables dynamic consumption of photovoltaic power, reducing carbon emissions from production. This invention acquires the power output of distributed photovoltaic power generation units in real time and dynamically adjusts the operating parameters of the microwave sterilization system based on the photovoltaic output. This ensures that the microwave energy supply rate matches the renewable energy supply, maximizing the local consumption of green electricity, reducing curtailment and grid dependence, significantly reducing carbon emissions in the production process, and meeting the low-carbon product access requirements of high-end markets in the Middle East, Europe, and the United States.

[0054] Secondly, it ensures a balance between sterilization effectiveness and microbial activity. Based on material characteristics (moisture content, microbial content), this invention presets an energy density threshold range. When photovoltaic power fluctuates, it dynamically adjusts microwave power and / or material processing time to maintain the energy density of the actual input material between the lowest and highest thresholds. This ensures that the kill rate of miscellaneous bacteria meets the standard while avoiding excessive sterilization that could damage the activity of encapsulated microorganisms, thus guaranteeing product quality stability.

[0055] Third, in scenarios with insufficient power, the invention extends the processing time to compensate for energy. When the real-time power generation is lower than the required microwave power, the invention automatically adjusts the microwave power to the current available photovoltaic power. By calculating the ratio of the required total sterilization energy to the real-time power, the material processing time is extended accordingly, ensuring that the total sterilization energy received per unit mass of material is consistent with that under standard operating conditions, thus solving the problem of insufficient sterilization caused by the intermittency of photovoltaic power generation.

[0056] Fourth, multiple safety protection mechanisms ensure stable system operation. This invention monitors the current energy density value in real time. When it falls below the minimum threshold, it automatically replenishes power from the energy storage unit or the power grid to ensure the sterilization effect. When it exceeds the maximum threshold, it automatically reduces microwave power or activates backup load to protect microbial activity and avoid equipment overload, forming a complete photovoltaic-microwave coordinated control closed loop.

[0057] Based on and Figure 1 Based on the same principle as the method shown, this embodiment of the invention also provides a dynamic control device 20 for a microwave sterilization system driven by distributed photovoltaics, such as...

[0058] Furthermore, when the aforementioned target operating parameter determination module 220 dynamically calculates the target operating parameters of the microwave sterilization system based on the real-time power generation and the preset sterilization energy requirements, it is specifically used for: The energy density threshold range required for sterilization is determined based on the material characteristics.

[0059] Furthermore, when the aforementioned target operating parameter determination module 220 compares the required microwave power with the real-time power generation and determines the target operating parameters based on the comparison results, it is specifically used for: If the real-time power generation is greater than or equal to the required microwave power, the required microwave power is determined as the target microwave power, and the standard processing time is determined as the target material processing time. If the real-time power generation is less than the required microwave power, the real-time power generation is determined as the target microwave power. Based on the preset energy density setting, the current batch material quality, and the real-time power generation, the extended processing time is determined and used as the target material processing time.

[0060] Furthermore, when adjusting the current operating parameters of the microwave sterilization system according to the target operating parameters, the aforementioned control module 230 is specifically used for: If the target operating parameters include the target microwave power, then adjust the operating parameters of the microwave power generator of the microwave sterilization system to adjust the current microwave power to the target microwave power. The operating parameters include the anode voltage and / or duty cycle. If the target operating parameters include the target material processing time, then adjust the operating speed of the material conveying device of the microwave sterilization system to adjust the current material processing time to the target material processing time. The operating speed includes the conveyor belt speed.

[0061] Furthermore, the device also includes an adjustment module for performing the following steps: Obtain the current material flow rate of the material entering the microwave sterilization system; Calculate the current energy density value based on the current material flow rate and real-time power generation. Determine whether the current energy density value is between the minimum energy density threshold and the maximum energy density threshold; If the current energy density value is lower than the minimum energy density threshold, then power is supplemented from the energy storage unit or the grid so that the actual energy density after supplementing the power reaches the minimum energy density threshold. If the current energy density value is higher than the maximum energy density threshold, reduce the microwave power of the microwave sterilization system or activate the backup load to reduce the adjusted actual energy density to below the maximum energy density threshold.

[0062] Furthermore, the aforementioned material characteristics include the moisture content of the material entering the microwave sterilization system and the content of microorganisms in the material.
