Waste solar panel treatment plant

Products obtained from pyrolysis of solar panels

Silicon wafers, as the core components of solar panels, play a crucial role in photovoltaic technology. When solar panels have been used for a certain period of time or need to be discarded for other reasons, the silicon wafers and other materials inside them face the problem of recycling and disposal. The pyrolysis of solar panels is one of the key steps in achieving resource reuse and environmental protection.

The pyrolysis products of solar panels mainly include organic matter, inorganic matter, and rare metals. Through advanced pyrolysis technology, these materials can be effectively separated and recovered. Organic matter can be transformed into fuel or chemical raw materials through pyrolysis treatment, achieving energy reuse. Materials such as silicon and glass in inorganic materials, after purification and treatment, can be used to manufacture new solar panels or other related products, continuing their application value.

In addition, solar panels also contain some rare metal elements, such as silver and copper. Although these metals are not used in large quantities in the production process of solar panels, their value is very high. Through pyrolysis technology, these rare metals can be effectively recycled and utilized, not only avoiding resource waste but also reducing potential environmental hazards.

It is worth noting that the treatment of thermal decomposition products from solar panels requires professional technical and equipment support. During the pyrolysis process, it is necessary to strictly control parameters such as temperature and pressure to ensure the quality and safety of the products. At the same time, effective treatment is also needed for the generated pollutants such as exhaust gas and wastewater to prevent secondary pollution to the environment.

In summary, the treatment of pyrolysis products from solar panels is an important means to achieve resource reuse and environmental protection. With the continuous development of photovoltaic technology and the expansion of application scale, the treatment and recycling of discarded solar panels will become increasingly important. In the future, through technological innovation and industrial upgrading, we are expected to achieve more efficient and environmentally friendly treatment and utilization of solar panel pyrolysis products.

The necessity of solar panel recycling and processing:

1. Resource protection: Solar panels are made from rare metals and other limited resources. Recycling and processing waste solar panels can effectively recover these resources, reduce the exploitation and consumption of natural resources, and contribute to the sustainable utilization of resources.

2. Environmental protection: Waste solar panels may contain harmful substances such as lead, cadmium, and other heavy metals. If these waste solar panels are discarded or mishandled, they may cause pollution to the soil and groundwater, posing a threat to the ecological environment and human health. Recycling and processing waste solar panels can safely dispose of these harmful substances and reduce their negative impact on the environment.

3. Energy utilization: Waste solar panels still contain reusable solar cells. By recycling these battery cells, the energy inside can be reused, reducing the manufacturing cost of batteries and their dependence on natural energy.

4. Economic benefits: The solar panel industry is increasingly developing, and the recycling and treatment of waste solar panels has become a potential economic industry. Recycling waste solar panels can create job opportunities and promote economic development.

Process principle of processing equipment:

Its pyrolysis process does not require fine treatment of impurities such as sediment, water, copper wire, etc. in the raw materials. It can directly load the waste solar panels containing organic waste after physical and mechanical treatment into the thermal pyrolysis processor. A small amount of glass, silicon and other substances can be separated from EV glue. EV glue can distill a mixture of oil and steam, which is condensed into fuel oil through a multi-stage separator and a cooling system. The solid substances are retained in the pyrolysis furnace. The exhaust gas smoke and dust from the carbonization pyrolysis processor are treated by the atomization smoke and dust device and discharged to meet the standard; A portion of low-carbon non condensable gas enters the combustible gas recovery system through water sealing and is used as fuel for combustion in the pyrolysis furnace. After carbonization, the solid material is cooled out of the furnace and then subjected to physical and mechanical screening to obtain metal materials such as silicon, copper, silver, and glass.
