At present, with the rapid development of the photovoltaic industry, a large number of photovoltaic panels are constantly being put into use as positive sources. But few people know that photovoltaic panels also have a service life, usually around 25 to 30 years. According to relevant data, it is predicted that by 2030, the cumulative retirement amount of waste photovoltaic panels in China will reach 1 million tons, and it may soar to 55 million tons by 2050. Such a large amount of waste photovoltaic panels, if not properly disposed of, will not only occupy a large amount of land resources, but also contain heavy metals such as lead and cadmium that can pollute soil and water sources, causing incalculable damage to the ecological environment.
However, now an innovative waste photovoltaic panel recycling device has emerged, which is like a magical key that can solve environmental problems and open the door to wealth. This device is carefully crafted by a professional team, with easy operation and fully automated operation, without the need for complex manual intervention.
The workflow of the equipment is clear and efficient. Firstly, the waste photovoltaic panels are fed into an intelligent frame removal machine, where the laser positioning system instantly locks the seam between the aluminum frame and the glass panel. The robotic arm, equipped with a specially made alloy cutting tool, precisely cuts along the sealing adhesive layer. Combined with a vacuum suction cup, the aluminum frame can be completely peeled off, with a recovery rate of over 99%. These recycled aluminum frames, after simple processing, can be reused to manufacture new photovoltaic brackets.
After peeling off the frame, the main body of the photovoltaic panel enters the layering stage. The fully automatic crushing equipment crushes it into particles of 5-10 millimeters, and then uses advanced airflow sorting technology to cleverly separate glass from plastic. After removing impurities through magnetic separation, glass particles can be transformed into photovoltaic module covers or used as building soundproofing materials; EVA film and other plastics are transformed into environmentally friendly recycled plastics through pyrolysis technology, which can be used to make cable protective covers, etc.
The core process of silicon wafer recycling is also very precise in terms of equipment handling. Firstly, dissolve the silver paste electrode on the surface with chemical reagents, and the purity of the recovered silver powder can reach 99.5%; Then, plasma etching technology is used to remove the surface aging part, purifying the native silicon material and returning it to the production of semiconductor grade silicon wafers.
Taking a small recycling plant that processes 10 tons of waste photovoltaic panels per day as an example, based on current market conditions, it can recycle about 6 tons of glass per day, worth 1200 yuan; 0.5 tons of aluminum frame, valued at 75000 yuan; 5 kilograms of silver, worth 250000 yuan; 3 tons of regenerated silicon, valued at 240000 yuan, with a total daily revenue of approximately 570000 yuan. After deducting the cost of board collection, equipment depreciation, labor and electricity fees, the daily net profit can reach 528000 yuan, and the income is quite considerable.
The recycling equipment for waste photovoltaic panels not only conforms to the trend of environmental protection, but also brings abundant economic benefits, making it the best choice for you to start a win-win business of environmental protection and wealth. Don’t hesitate anymore, seize the opportunity, help with environmental protection together, and create wealth for yourself!
