Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module disassembly and separation equipment, and specifically to a photovoltaic module disassembly and separation equipment based on pulsed laser. Background Art

[0002] In the industrial production and application market of photovoltaic modules, crystalline silicon photovoltaic modules (including monocrystalline silicon and polycrystalline silicon photovoltaic modules) are the most common module types, and their market share has always remained at 85% - 90%. The structure of crystalline silicon photovoltaic modules from top to bottom is glass, EVA, solar cells, EVA, and backplane. After each layer of material is laminated in vacuum, components such as aluminum frames and junction boxes are installed and encapsulated into photovoltaic modules. With the booming development of the global photovoltaic industry, as the most critical component in photovoltaic power stations, photovoltaic modules are facing large-scale resource loss and the diffusion of heavy metals in the environment. Recycling the secondary resources contained in waste photovoltaic modules will become an important way to solve environmental pollution problems and promote the sustainable development of the photovoltaic industry. China is the world's largest producer and user of photovoltaic modules, and it is particularly urgent to develop environmentally friendly, efficient, and low-cost disassembly technologies for waste photovoltaic modules.

[0003] The industrialization of retired photovoltaic module recycling essentially transforms environmental costs into economic value through technological innovation, policy coordination, and ecological integration. Enterprises need to build a moat in technology research and development, break the linear thinking in business models, and build a four-dimensional driving system of "policy - technology - capital - market".

[0004] The current recycling and reuse of retired photovoltaic modules mainly rely on heat treatment, while laser disassembly technology is regarded as the next development direction. This phenomenon is mainly based on comprehensive considerations of factors such as technology maturity, economy, environmental protection requirements, and material recycling efficiency.

[0005] I. The advantages of currently using heat treatment technology are as follows:

[0006] 1. High technology maturity

[0007] Heat treatment (such as high-temperature incineration, pyrolysis, etc.) is a widely used separation technology in industry and has formed a standardized process. By decomposing the EVA (ethylene-vinyl acetate) film in photovoltaic modules at high temperature (500 - 600 °C), materials such as glass, silicon wafers, and metals can be quickly separated. This method has a simple process and relatively low equipment cost, and is suitable for large-scale processing.

[0008] 2. Adapt to the existing recycling system

[0009] Currently, the number of retired photovoltaic modules has not reached the stage of "explosive growth", and traditional heat treatment technology can meet the current processing requirements. In addition, many recycling plants are already equipped with facilities such as high-temperature incinerators and can be compatible with photovoltaic module processing without additional investment.

[0010] 3. Higher material separation efficiency

[0011] Heat treatment can effectively decompose organic adhesives (such as EVA), releasing intact glass, aluminum frames, and silicon wafers. For the early market dominated by crystalline silicon modules, heat treatment can recover approximately 80% of the glass and metal, meeting the basic recycling goals.

[0012] 4. Economic advantages

[0013] The initial investment and operating costs are relatively low, and the recycled metals (such as silver and aluminum) can be directly sold, resulting in obvious short-term benefits, making it suitable for the current economy-oriented recycling market.

[0014] II. The advantages of current laser disassembly technology are as follows:

[0015] 1. High precision and material recovery rate

[0016] Laser technology can accurately strip each layer of materials in the module (such as glass, EVA, backsheet, and cells) through non-contact energy focusing, avoiding high-temperature damage to silicon wafers or rare metals (such as silver grid lines);

[0017] 2. Environmental protection advantages

[0018] Laser technology does not require high-temperature combustion, avoiding the emission of toxic gases such as dioxins and fluorides, and meeting future strict environmental protection regulations (such as the EU Waste Framework Directive). At the same time, no chemical solvents are used, reducing the risk of secondary pollution.

[0019] 3. Potential for automation and intelligence

[0020] Laser disassembly can be combined with robots and AI vision systems to achieve fully automated sorting and processing, reducing labor costs and improving efficiency.

[0021] 4. Adaptability to new module structures

[0022] In the future, photovoltaic modules will tend to be more diverse (such as heterojunction, perovskite, and tandem cells), with more complex structures, making it difficult for traditional heat treatment to efficiently separate them.

[0023] 5. Better long-term economy

[0024] Although the initial cost of laser equipment is high (about 2 - 3 times that of heat treatment equipment), its material recovery value is higher (such as the recovery rates of silicon and silver increasing by more than 30%), and the long-term operating costs are lower, meeting the trend of circular economy.

[0025] In the existing photovoltaic module disassembly and separation equipment, the lack of a "heat treatment + laser" hybrid mode makes it difficult to achieve good peeling between EVA and glass during the disassembly process, and it is prone to damage during the peeling process, affecting the recycling of the peeling.

[0058] During use, place the photovoltaic module to be disassembled in the placement cavity 28 within the placement tank body 3 of the device, and push the placement tank body 3 into the furnace chamber 21 so that the sealing door 2 is tightly closed. Through the control system of the device, set the heating temperature of the heating element 22, the monitoring ranges of the air pressure sensor 27, the temperature sensor 33, and the pressure sensor 18. Start the heating element 22 to heat the furnace chamber 21 until the temperature inside the furnace chamber 21 reaches the preset value. At the same time, start the air pump 23, open the first solenoid valve 25 on the first air duct 24, and close the first solenoid valve 25 on the second air duct 26. Fill the furnace chamber 21 with gas through the first air duct 24, making the inside of the furnace chamber 21 in a high-pressure state. During this process, the air pressure sensor 27 monitors the air pressure inside the furnace in real time to ensure that the air pressure inside the furnace remains stable during heating.

After maintaining the high-temperature and high-pressure state inside the furnace chamber 21 for a certain period of time, stop the operation of the heating element 22, open the first solenoid valve 25 on the second air duct 26, so that the gas inside the furnace chamber 21 is quickly discharged into the gas recovery tank 5 to relieve the pressure inside the furnace chamber 21. At the same time, since the third liquid guide pipe 30 is connected to the cold water supply tank through the hose 31, and the fourth liquid guide pipe 32 is connected to the recovery tank through the hose 31, open the second solenoid valve 36, so that the cold water enters the cooling chamber 29 through the third liquid guide pipe 30 to cool the space where the photovoltaic module is located. After the cold water absorbs heat, it is discharged into the recovery tank through the fourth liquid guide pipe 32. By continuously injecting cold water and discharging hot water through the third liquid guide pipe 30 and the fourth liquid guide pipe 32, the photovoltaic module can be quickly cooled down.To achieve the purpose of completely separating EVA from the glass, among which the air pressure sensor 27, the temperature sensor 33 and the pressure sensor 18 all adopt sensors that can withstand high temperatures.
