Products Detail
Waste PV panel recycling can be done through a combination of dismantling, pyrolysis and crushing and sorting processes, which can quickly pyrolyse solar PV panels. From refining fuel oil. And extract from it: silicon, silver, glass, copper and other valuable metal materials. The recovered materials can be reused again. It can be re-surplus photovoltaic panel production or other products. So as to achieve the recycling of resources.
Waste solar photovoltaic panel pyrolysis is mainly based on physical, chemical and thermodynamic principles. Through high temperature pyrolysis furnace for cracking and incineration. The waste photovoltaic panels will be finely recycled. The high-temperature environment can prompt the transformation of the materials of the photovoltaic panels. Thus, the separation and recycling of materials can be achieved.
Raw Materials
Solar photovoltaic panels, monocrystalline silicon photovoltaic panels, polycrystalline silicon photovoltaic panels, single-glass and double-glass photovoltaic panels, etc.
Advantageous
1. High resource recovery rate, which can effectively separate multiple materials in PV panels and maximise resources.
2. Pyrolysis technology reduces the emission of hazardous substances and reduces environmental pollution.
3. The recovered materials can be reused in the production of PV panels, thus reducing production costs.
4. the gas and electricity consumption of pyrolysis furnace is more than 10% lower than that of traditional pyrolysis furnace.
5. the equipment adopts more intelligent design concept, low failure rate, convenient maintenance, less down time.
6. Equipped with automated PLC control system, real-time monitoring can be realised.
Technological Process
Workers load the pre-disassembled waste PV panels into the solar PV panel pyrolysis furnace by forklift or automatic feeding machine after processing the modules. Start the fuel oil heating machine (1 pyrolysis equipment supporting 4 sets of fuel oil heating machine) to heat the pyrolysis furnace, this heating method is indirect heating. The heating temperature is controlled at 350℃ and the heating time is 5 hours.
Process principle: the main component of EVA in PV module is ethylene vinyl acetate, and the main components of TPT backsheet are polyvinyl fluoride (PVF) and polyester film (PET). Using EVA, PVF, PET and other substances with low pyrolysis temperature, EVA, PET, PVF pyrolysis occurs during the heating process. This process generates noise and exhaust gases. Thermal treatment refers to the pyrolysis of EVA, PVF, PET and other substances under anaerobic or anoxic conditions and appropriate temperatures.EVA pyrolysis products are small molecules. EVA pyrolysis products are small molecules, mainly carbon dioxide, methane, ethylene, ethane and other alkanes and olefins below C4.PET under heating conditions, ester bond breaking occurs. The products are carbon dioxide, carbon monoxide, acetaldehyde and aromatic compounds, etc. The pyrolysis products of PVF are mainly hydrogen fluoride, hydrofluorocarbons, alkanes, olefins, etc. After condensing the pyrolysis gas, fuel is obtained. Fuel oil is obtained after condensing the pyrolysis gas, and the non-condensable gas is burned in the combustion chamber (no other fuel is needed). After combustion, the flue gas is treated and discharged through a 15-metre chimney.
