What is the design of 500kg/h solar panel processing line? How to achieve high-value recycling of materials? YUSHUNXIN Tecnologia di pirolisi fotovoltaica provides a solution for the core process of this production line. It not only boosts material recovery rates to over 98%, but also achieves zero pollution emissions throughout the production process.

What is the design concept for the entire line?

The 500kg/h solar panel recycling production line centers on a continuous pyrolysis reaction system, and the design aims to achieve stable, continuous feedstock inflow and outflow. Through the integration of modules such as automatic feeding, pyrolysis reaction, condensation recovery, and metal separation, it can maintain production balance at a processing capacity of 500 kg/h, which avoids energy loss and efficiency fluctuations caused by manual intervention.

IL Soluzione di progetto di pirolisi del pannello solare operates on the principle of energy self-circulation. The system can recover and utilizes the combustible gases generated during pyrolysis as heating fuel or for energy supply. This energy recovery design significantly reduces power consumption, and improves the overall energy utilization rate of the line to over 85%.

YUSHUNXIN prioritizes exhaust gas purification and safe tail gas treatment in its design, incorporating multi-stage condensation and adsorption systems to ensure emissions meet EU environmental standards. Nel frattempo, it is equipped with an intelligent control safety module featuring functions such as gas leakage monitoring, automatic flameout protection, and abnormal alarm systems, which ensures the stability and safety of the system during long-term operation.

To accommodate varying production capacity requirements across different stages of enterprise development, the 500kg/h production line employs a modular configuration. If you require to expand production capacity, you can quickly scale up to a 1t/h capacity through parallel expansion.

What are the core process steps?

Intelligent Frame Removal and Junction Box Disassembly

Step 1: Intelligent Frame Removal and Junction Box Disassembly

The modules first enter the fully automatic frame removal machine. Robotic arms locate the aluminum frame positions, and the hydraulic cutting system completes separation of all four sides within 10 seconds. The aluminum frame recycling purity reaches 99%. Successivamente, infrared thermal imaging locates the junction box positions, and the robot performs non-destructive removal, ensuring a junction box reusability rate exceeding 90%.

Step 2: Laminate Crushing and Preliminary Sorting

Laminates removed from the frame enter the low-temperature crushing system. IL trituratore di rifiuti elettronici crushes the materials, which initially separates the glass, celle solari, e backsheet. After crushing, the material passes through a vibrating screen. Material larger than 5mm returns to the crusher for reprocessing, while the mixture smaller than 5mm proceeds to the next process.

Pyrolysis Separation

Step 3: Pyrolysis Separation

The mixed material enters a sealed low-temperature pyrolysis furnace. At 450°C under an oxygen-free environment, EVA and backsheet polymers decompose into condensable oil, gas and carbon black. Dopo la pirolisi, wafer di silicio, metalli, and glass in the material are thoroughly loosened, which creates ideal conditions for subsequent sorting.

Step 4: Ordinamento a più stadi

Dopo la pirolisi, the material enters an eddy current separator to extract copper-welded strips and alluminio particles, achieving a purity of 98%. Prossimo, the high-voltage electrostatic separator separates silicon particles from glass powder, achieving a 95% separation efficiency based on differences in electrical conductivity. Poi, the air separator further purifies the silicon material, and removes residual plastic fragments.

Dust Control and Exhaust Gas Treatment

Step 5: Dust Control and Exhaust Gas Treatment

IL gestione del riciclo dei pannelli solari features a centralized dust collection system with negative pressure collection. Exhaust gases undergo secondary combustion, rapid cooling, and activated carbon adsorption treatment throughout the process, which reduces the risk of dioxin emissions exceeding standards by 99%.
