Process and equipment for recovering photovoltaic component through thermal high-speed centrifugal decomposition

Abstract

The invention discloses a process for recovering a photovoltaic component through thermal high-speed centrifugal decomposition. The steps of heating, centrifugal separation and classified recovery are sequentially performed, each material component in the photovoltaic component is gradually melted at high temperature in the whole treatment process, and burning operation is not needed, so that poisonous gas generated by burning related rubber and plastic material components is avoided, the influence of the decomposition recovery process of the photovoltaic component on ambient environment is reduced, and the treatment process is more environment-friendly. Meanwhile, the melted components made of different materials are respectively recovered in a centrifugal separation mode, so that the purity of the recovered single material is improved; and the chemical properties of the materials are not obviously changed, so that the materials are easier to recover, the condition that the materials are wasted because the chemical properties of the materials are changed and the materials cannot be reused is avoided, and the utilization rate of the materials is obviously improved. The invention also discloses equipment for recovering the photovoltaic component through thermal high-speed centrifugal decomposition, which is used for the process for recovering the photovoltaic component through thermal high-speed centrifugal decomposition.

Problems solved by technology

[0004] However, although the above-mentioned treatment methods can meet the basic needs of decomposition and recycling of photovoltaic modules, due to the incineration of rubber and plastic components such as EVA and PVB, and components supported by combustible materials such as backplanes, a large amount of toxic gases will be generated, causing damage to the surrounding environment. The atmospheric environment has caused serious damage, and the chemical properties of the combustible materials after incineration have undergone fundamental changes, which cannot be reused, resulting in waste of materials; the chemical properties of various crystalline silicon materials, metal materials and glass materials have also changed during the incineration process. It will cause denaturation or damage, which will increase the difficulty of subsequent related recycling work

[0005] Therefore, how to make the decomposition and recycling process of photovoltaic modules more environmentally friendly and avoid material waste in the decomposition and recycling process is an important technical problem that those skilled in the art need to solve at present.
