Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic waste resource utilization, and specifically relates to a chemical treatment method and system for waste solar panels based on intelligent control. Background Art

[0002] As environmental issues caused by traditional fossil fuels become increasingly severe, the development of renewable energy has garnered widespread attention, with solar energy development and utilization technology becoming a mainstream focus. Solar photovoltaic power generation offers advantages such as a wide range of energy sources, flexible deployment, low maintenance costs, and a low environmental impact. These advantages have led to the rapid development of solar panel power generation in recent years, with widespread application in various fields, including industry and agriculture.

[0003] As the scale of solar panel power generation gradually expands, the recycling and treatment of waste solar panels has become a new technical challenge. However, the existing waste solar panel processing system has problems such as high recycling costs, low recovery rate of precious metals such as electrodes, and waste pollutant emissions. In addition, the chemical treatment of precious metals requires manual addition of strong acids such as hydrofluoric acid or nitric acid, which can easily cause harm to operators. Summary of the Invention

[0004] The purpose of the present invention is to provide a chemical treatment method and system for waste solar panels based on intelligent control, so as to overcome the risk problem of workers being exposed to high-risk environments during the existing waste solar panel treatment process.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions: A chemical treatment system for waste solar panels based on intelligent control, comprising: Pre-processing module: including a visual recognition device, which is used to identify whether there are electrodes on the surface of the waste solar panels through machine vision; Dissolution module: includes a robotic arm and a fully enclosed reaction chamber. The robotic arm is used to transport waste solar panels and add hydrofluoric acid to the fully enclosed reaction chamber to dissolve the electrode metal on the surface of the waste solar panels. The fully enclosed reaction chamber is used to dissolve the waste solar panels. Recovery module: includes a solid-liquid separator, an electrolytic separator, and a silver ion purification device. The solid-liquid separator is used to separate the dissolved solid and liquid, the electrolytic separator is used to ionize the separated liquid, and the silver ion purification device is used to purify the ionized liquid to obtain metallic silver; Regeneration module: includes a pH detection device and an osmotic pressure separator. The waste liquid obtained by electrolytic separation is subjected to pH detection using the pH detection device. The osmotic pressure separator is used to process and recover the waste liquid with a pH value below the threshold to obtain hydrofluoric acid for reuse.

[0006] Furthermore, the dissolution module also includes a feedback pressure measuring device for monitoring the pressure of the fully enclosed reaction chamber.

[0007] Furthermore, a spectral imaging sensor and a laser-assisted stripping device are installed at the end of the robotic arm.

[0008] Furthermore, the recovery module also includes a dryer for heat treatment of the separated solids.

[0009] Furthermore, the fully enclosed reaction chamber has a built-in titanium alloy liner, and a lifting partition is provided in the fully enclosed reaction chamber.

[0010] Furthermore, it also includes a waste gas treatment module for treating the waste gas generated during the hydrofluoric acid recovery process using a low-temperature plasma reactor and an activated carbon adsorption tower.

[0011] In a second aspect, a method for chemically treating waste solar panels based on intelligent control is provided, comprising the following steps: Use a visual recognition device to identify whether there are electrodes on the surface of the waste solar panels. If so, use a robotic arm to place the waste solar panels into a fully enclosed reaction chamber; Add hydrofluoric acid to a fully enclosed reaction chamber to dissolve the electrode metal on the surface of the waste solar panels, and calculate the hydrofluoric acid concentration required to dissolve all the electrode metal on the surface of the waste solar panels based on the reinforcement learning algorithm; The waste solar panels dissolved in hydrofluoric acid are separated into solid and liquid by a solid-liquid separator, and the dissolved liquid is subjected to an electrolytic separator to obtain a silver ion suspension, which is then purified by a silver ion purification device to obtain metallic silver; The waste liquid from which the silver ions are separated is tested for pH using a pH detection device. When the pH value is lower than a threshold value, the waste liquid from which the silver ions are separated is treated using an osmotic pressure separator, and hydrofluoric acid is recovered for reuse.

[0012] Furthermore, if there is no electrode on the surface of the waste solar panel, the waste solar panel is directly subjected to heat treatment.

[0013] Furthermore, the solid separated by the solid-liquid separator is heat-treated using a dryer.

[0014] Furthermore, the threshold of the pH value is 2.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides a chemical treatment system for waste solar panels based on intelligent control, comprising a pretreatment module, a dissolution module, a recovery module, and a regeneration module. The pretreatment module accurately identifies whether electrodes are present on the surface of waste solar panels, avoiding ineffective chemical treatment of panels without electrodes and reducing resource waste. The dissolution module uses a robotic arm to replace manual labor to complete the high-risk addition of hydrofluoric acid and panel transfer. The fully enclosed reaction chamber eliminates strong acid exposure and pollutant leakage, completely eliminating the risk of high-risk environmental exposure for operators. The recovery module achieves efficient recovery of precious metal silver in electrodes through solid-liquid separation, electrolytic ionization, and silver ion purification. The regeneration module recovers hydrofluoric acid for reuse in waste liquid with a pH value below a threshold, reducing the discharge of acidic waste liquid. The present invention ensures that each process can be completed efficiently through the collaboration of various modules, achieving low-cost and pollution-free treatment of waste solar panels. The system places the chemical dissolution process in a fully enclosed reaction chamber to avoid irreversible chemical damage that may be caused by manual operation. The present invention solves the high-risk operation risks in the chemical treatment of waste solar panels, improves the recovery rate of precious metals, reduces environmental pollution, and significantly reduces treatment costs.

[0016] Preferably, the dissolution module is additionally provided with a feedback pressure measuring device to monitor the pressure of the fully enclosed reaction chamber, and can determine in real time whether the fully enclosed reaction chamber is leaking, thereby ensuring the sealing property.

[0017] Preferably, the waste gas generated during the hydrofluoric acid recovery process is treated by a low-temperature plasma reactor and an activated carbon adsorption tower of the waste gas treatment module to prevent the waste gas from polluting the atmospheric environment.

[0018] The present invention provides an operating method for a liquid metal battery energy storage system. After the waste solar panels undergo a pretreatment process of removing external parts such as frames and wires, an algorithm is used to calculate the required amount of hydrofluoric acid and reaction time based on the existing processing capacity. After the calculation is completed, acid dissolution begins. After sufficient dissolution, the solid waste is separated by a solid-liquid separation device and heat-treated. The electrolytic separation liquid dissociates into a metal ion suspension and waste liquid. The waste liquid is detected in a pH detection module and enters a corresponding processing flow according to the pH value result. The present invention integrates the chemical treatment process of waste solar panels with an AI intelligent algorithm, so that the chemical treatment process of electrode metal dissolution is always in the most efficient state under dynamic detection. The chemical treatment process of waste solar panels is placed in a fully enclosed reaction chamber, which solves the problem of toxic and harmful gases escaping during the dissolution process during conventional chemical treatment, and avoids the risk of operators being exposed to a volatile strong acid environment during the process, thereby improving the working environment of practitioners and avoiding toxic and harmful byproducts from polluting the environment.

[0019] After the solution is separated, its pH value is tested. When the pH value is lower than the expected value, it is recycled and reused, which reduces costs and also reduces the emission of acidic gases. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of 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. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0025] The present invention provides a chemical treatment system for waste solar panels based on intelligent control, which includes the following parts: Pre-processing module: used to identify whether there are electrodes on the surface of the waste solar panels through machine vision. If so, the waste solar panels are placed into the fully enclosed reaction chamber 4 through the robotic arm 2; Dissolution module: used to add hydrofluoric acid into the fully enclosed reaction chamber 4 to dissolve the electrode metal on the surface of the waste solar panels, and calculate the hydrofluoric acid concentration required to dissolve all the electrode metal on the surface of the waste solar panels based on the reinforcement learning algorithm; Recovery module: used to electrolyze and separate the dissolved liquid to obtain a silver ion suspension and then purify it to obtain metallic silver; Regeneration module: used to process the liquid after the silver ions are separated and recover the hydrofluoric acid for reuse.

[0026] Specifically, such as Figure 1 As shown, the pre-processing module includes a visual recognition device 1, which is used to identify whether there are electrodes on the surface of the waste solar panel through machine vision. If there are electrodes, the waste solar panel is placed into a fully enclosed reaction chamber 4 through a robotic arm 2; The dissolution module includes a fully enclosed reaction chamber 4 and a robotic arm 2. The robotic arm 2 is used to transport the waste solar panels and add hydrofluoric acid to the fully enclosed reaction chamber 4 to dissolve the electrode metal on the surface of the waste solar panels. The robotic arm 2 calculates the hydrofluoric acid concentration required to dissolve all the electrode metal on the surface of the waste solar panels based on the reinforcement learning algorithm. The fully enclosed reaction chamber 4 is used to dissolve the waste solar panels. The recovery module includes a solid-liquid separator 5, an electrolytic separator 7 and a silver ion purification device 8. The solid-liquid separator 5 is used to separate the solid and liquid after dissolution. The separated liquid is separated by the electrolytic separator 7 to obtain a silver ion suspension, which is then purified in the silver ion purification device 8 to obtain metallic silver. The regeneration module includes a pH detection device 9 and an osmotic pressure separator 10. The waste liquid obtained by electrolytic separation is subjected to pH detection by the pH detection device 9. The osmotic pressure separator 10 is used to treat the waste liquid with a pH value below the threshold and recover the hydrofluoric acid for reuse.

[0027] Among them, the fully enclosed reaction chamber 4 contains a lifting partition, and the dissolution module also includes a feedback pressure measuring device 3 for monitoring the pressure of the fully enclosed reaction chamber 4. The feedback pressure measuring device 3 is used to determine whether the fully enclosed reaction chamber 4 is leaking. The lifting partition is used to separate the solid waste inside after the dissolution process is completed; a hyperspectral imaging sensor and a laser-assisted stripping device are installed at the end of the robotic arm 2. The hyperspectral imaging sensor is used to detect the thickness of the silver paste on the surface of the silicon wafer in real time, and feed the data back to the AI ​​control center. By adjusting the acid injection volume, the dynamic balance of the acid in the fully enclosed reaction chamber 4 is achieved; the laser-assisted stripping device is used to disassemble and separate bulk metal to ensure reaction time and reaction efficiency.

[0028] The recycling process for used solar panels consists of three steps: pretreatment, chemical treatment, and thermal treatment. During pretreatment, the panels' outer frames and connecting wires are removed for recycling. This invention addresses the post-pretreatment chemical treatment process, which aims to recover the precious metals from the panels' electrodes.

[0029] The present invention proposes a chemical treatment system for waste solar panels based on intelligent control. For pre-treated waste solar panels, the system can dissolve the precious metals on the solar panel electrodes in a fully enclosed environment. The intelligent algorithm and AI control system calculate the acid concentration and treatment time required to treat the current waste solar panels. A visual recognition device 1 is installed in the system to ensure that the precious metals in the electrodes are fully dissolved in the process. The dynamic pH monitoring can not only indirectly reflect the metal dissolution rate, but also detect the concentration of each component in the waste liquid after the reaction is completed. When the concentration of each component is within the expected range, it can be further harmlessly treated to complete the entire chemical treatment process. The system realizes the full monitoring of the chemical treatment of waste solar panels. Under the integration of intelligent algorithms, it ensures that the system completes the recovery of precious metals in the electrodes at the optimal speed and with the least amount of strong acid. In addition, the fully sealed treatment not only solves the risk of workers being exposed to high-risk environments, but also prevents the leakage of potential high-risk pollutants in the process into the external environment, thereby realizing the harmless treatment of waste solar panels.

[0030] Optionally, the present invention proposes a chemical treatment system for waste solar panels based on intelligent control, which is composed of multiple process modules and an AI control system. Intelligent image recognition is used to detect and identify pre-treated waste solar panels, and then electrode metal dissolution and solid-liquid separation are completed in a fully enclosed reaction chamber 4. The AI ​​control system monitors various parameters of the entire process in real time to ensure that each process can be completed efficiently and achieve low-cost and pollution-free treatment of waste solar panels. At the same time, the system places the chemical dissolution process in a fully enclosed reaction chamber 4 to avoid irreversible chemical damage that may be caused by manual operation.

[0031] like Figure 2 As shown, the present invention provides a chemical treatment method for waste solar panels based on intelligent control, comprising the following steps: The visual recognition device 1 is used to identify whether there are electrodes on the surface of the waste solar panel. If there are electrodes, the robot arm 2 is used to place the waste solar panel into the fully enclosed reaction chamber 4; Adding hydrofluoric acid into the fully enclosed reaction chamber 4 to dissolve the electrode metal on the surface of the waste solar panels, and calculating the hydrofluoric acid concentration required to dissolve all the electrode metal on the surface of the waste solar panels based on the reinforcement learning algorithm; The waste solar panels dissolved in hydrofluoric acid are separated into solid and liquid by a solid-liquid separator 5, and the dissolved liquid is subjected to an electrolytic separator 7 to obtain a silver ion suspension, which is then purified by a silver ion purification device 8 to obtain metallic silver; The waste liquid from which the silver ions are separated is subjected to a pH test using a pH detection device 9. When the pH value is lower than a threshold value, the waste liquid from which the silver ions are separated is treated using an osmotic pressure separator 10 to recover hydrofluoric acid for reuse.

[0032] Detailed steps such as Figure 3 As shown: 1) Using machine vision to identify the size of used solar panels and the distribution of silver electrodes on the silicon wafer surface, a 3D thickness map of the electrode distribution is generated; 2) A reinforcement learning algorithm calculates the optimal hydrofluoric acid concentration, reaction time, and laser ablation path; 3) Robotic arm 2 immerses the silicon wafer into the acid reaction tank and starts laser-assisted stripping at the same time; 4) Recover silver ions from wastewater by electrolysis, obtain a silver ion suspension, and then purify it. The processing standard is purity ≥99%; 5) The waste liquid is tested for pH value. If the pH value is less than 2, it enters the waste liquid recovery module, where hydrofluoric acid is separated by electrodialysis and then enters the distillation tower for purification. The waste gas is purified in two stages before it meets the emission standards. 6) The waste liquid is treated harmlessly and the solid waste residue is subjected to the next step of heat treatment.

[0033] Detailed, such as Figure 3 As shown, including: Pre-treatment: The visual recognition device 1 is used to detect whether there are electrodes on the surface of the waste solar panels. If there are no electrodes, they are directly sent to the heat treatment process; if there are electrodes, the robot arm 2 loads them into the fully enclosed reaction chamber 4; Dissolution reaction: Based on big data and reinforcement learning algorithms, the required hydrofluoric acid concentration and reaction time are calculated; robotic arm 2 injects hydrofluoric acid, and a laser-assisted stripping device assists in disassembling the metal block; a hyperspectral imaging sensor monitors the dissolution state in real time and dynamically adjusts the acid volume; Solid-liquid separation: After dissolution is completed, the solid waste and the liquid are separated; the solid waste is removed from the fully enclosed reaction chamber 4 for deacidification and heat treatment; Precious metal recovery: The liquid is electrolytically separated to obtain a silver ion suspension, which is then purified by chemical deposition to obtain metallic silver (purity ≥ 99%); Waste liquid treatment: The acidic waste liquid after silver ion separation is tested for pH. If the pH value is less than 2, it will be sent to the waste liquid regeneration unit to recover hydrofluoric acid; if the pH value is ≥2, it will be directly treated harmlessly. Waste gas treatment: The waste gas generated during the reaction is treated by a low-temperature plasma reactor and an activated carbon adsorption tower before being discharged in compliance with emission standards.

[0034] After the waste solar panels have undergone the pre-treatment process of removing the frames, wires and other external parts, the system's visual recognition device 1 will separate the part without metal electrodes from the chemical treatment process. The AI ​​algorithm then calculates the required amount of hydrofluoric acid and reaction time based on the existing processing capacity. After the calculation is completed, acid dissolution begins, and the robotic arm 2 assists in the dissolution process. When the calculated time is reached, the imaging device on the robotic arm 2 generates a spectrum with the assistance of AI to detect whether the electrode is fully dissolved. After sufficient dissolution, the solid-liquid separator 5 separates the solid waste and performs heat treatment. The electrolytic separator 7 dissociates the metal ion suspension and waste liquid. The waste liquid is tested by the pH detection device 9 and enters the corresponding treatment process according to the pH value result, thus completing the entire chemical reaction process.

[0035] After pretreatment, waste solar panels are screened before entering the fully enclosed reaction chamber 4. Visual recognition device 1 identifies and separates panels without electrodes. These panels can proceed directly to the next step, heat treatment. The remaining panels are sent to the fully enclosed reaction chamber 4 for chemical treatment. An intelligent imaging device on robotic arm 2 determines the distribution and quantity of electrode metal. After generating relevant data, a big data model calculates the hydrofluoric acid required to dissolve this portion of electrode metal (this example uses hydrofluoric acid dissolution of silver electrodes, a common electrode and dissolving acid in current chemical treatment processes) and the dissolution time. After this calculation, hydrofluoric acid is added to the fully enclosed reaction chamber 4. During this process, the laser disassembly device on robotic arm 2 assists in breaking down any lumps of metal electrode, accelerating the dissolution rate. When the calculated dissolution time is reached, the intelligent imaging device generates a spectrum to determine the dissolution of the electrode metal. If any undissolved metal remains, the intelligent algorithm regenerates the acid dosage and reaction time until the dissolution rate meets the expected level. After the metal electrode is completely dissolved, solid-liquid separation is performed using a solid-liquid separator 5. The solid waste is transported out of the fully enclosed reaction chamber 4 via a lifting partition within the fully enclosed reaction chamber 4 for deacidification and then enters a heat treatment process. The dissolved liquid enters an electrolytic separator 7 for an electrolytic process to dissociate into a silver ion suspension and an acidic waste liquid. The silver ion suspension is separated by electroosmosis and further recovered. The remaining waste liquid undergoes a pH test. If the pH is less than a specific value (usually a pH of 2), the acidic waste liquid enters a waste liquid recovery module, where it is separated by osmotic pressure or a molecular membrane to obtain a certain concentration of hydrofluoric acid, thereby enabling the recovery and reuse of the hydrofluoric acid.

[0036] Optionally, during the hydrofluoric acid recovery process, a low-temperature plasma reactor and an activated carbon adsorption tower are used to treat the waste gas generated during the hydrofluoric acid recovery process.

[0037] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited thereto. Within the technical concept of the present invention, various simple variations of the technical solution of the present invention may be made, including combining the various technical features in any other appropriate manner. These simple variations and combinations should also be regarded as disclosed in the present invention and fall within the scope of protection of the present invention.
