Photovoltaic panel treatment equipment is a kind of equipment aimed at and applied to waste photovoltaic panels, and its working principle is mainly through a series of physical and chemical methods to separate and extract useful materials in waste photovoltaic panels to achieve resource recycling.
The whole process of photovoltaic panel** processing equipment includes the following steps:
First of all, the waste photovoltaic panels are put into the silo of the ** processing equipment, and the photovoltaic panels are transported to the dismantling link through the conveying device. In the dismantling process, the dismantling robot will disassemble the outer frame of the photovoltaic panel, and then separate the junction box. Once the dismantling is complete, the PV panels are transported to the next process.
Next up is crushing and sorting. In this process, the photovoltaic panels are broken into small pieces, and then the metal and non-metal parts of the crushed photovoltaic panels are separated by a magnetic separator. In this process, materials such as glass, adhesive film, and backsheet are separated, and metals such as copper and aluminum are extracted.
This is followed by chemical treatment. In this process, the silicon wafers in the photovoltaic panels are chemically treated with a mixture of hydrofluoric acid and nitric acid to dissolve the impurities on the surface of the silicon wafers and purify the silicon wafers. After chemical treatment, the purity of the silicon wafer is significantly improved.
Resources** link. In this process, through various separation and purification techniques, various useful materials in photovoltaic panels will be extracted, and valuable resources such as copper, silicon, and silver with high purity will be obtained. These resources can be reused, thus enabling the recycling of resources.
Different from the traditional wind turbine blade manufacturing process, the process of photovoltaic panel processing equipment pays more attention to environmental protection and resource recycling. In this process, all waste photovoltaic panels can be reused, thereby reducing the waste of resources and pollution to the environment. At the same time, with the continuous advancement of new energy policies, the application prospects of photovoltaic panel processing equipment will also be broader.
In the future, with the continuous expansion of the photovoltaic market and the continuous advancement of new energy policies, the demand for photovoltaic panel processing equipment will be increasing. It is believed that in the near future, photovoltaic panel processing equipment will play a more important role in the field of new energy and make greater contributions to the development of China's new energy industry.
