Abstract

The invention discloses a device for recovering metals and energy gas from waste and old solar panels. The device comprises a multi-temperature zone vacuum heating device, a corundum tube, an assembled crucible, a vacuum pump and a gas collecting bottle. The corundum tube is arranged in the multi-temperature zone vacuum heating device. The assembled crucible is arranged in the corundum tube. The assembled crucible is composed of a plurality of assembled crucible bases. All the crucible bases are arranged corresponding to different heating temperature zone positions of the multi-temperature zone vacuum heating device. An inlet of the corundum tube is provided with a sealing cover A. The sealing cover A is provided with a venting valve and a venting pipe. An outlet of the corundum tube is provided with a sealing cover B. The sealing cover B is provided with a gas guiding tube connected to the vacuum pump. The gas guiding tube is provided with a vacuum pump valve. A gas outlet of the vacuum pump is connected to the gas collecting bottle through a conveying pipe. A vent pipe, a vent valve and a gas cylinder valve are arranged in the conveying pipe. The device realizes efficient and accurate recovery of metals, organic matters and silicon raw materials in waste and old solar panels and has the characteristics of simple structure, high efficiency recovery and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of solid waste recycling, in particular to a device for recovering metal and energy gas from waste solar panels. Background technique [0002] Solar energy is recognized as the cleanest and most abundant energy in the 21st century. In recent years, due to the deepening of the energy crisis, solar panels have been promoted for production and application. The lifespan of solar panels is generally 15 to 20 years. The annual production of solar panels in China is expanding rapidly, reaching 28.14% in 2016. Although the amount of solid waste related to solar technology is relatively small compared with that generated by traditional energy sources, the In the next 5 to 10 years, there will be a large number of waste solar panels to be disposed of urgently. Therefore, there is an urgent need for related technologies and equipment for solar panel processing to deal with the waste problem that will be faced. From t...
