Separating device and recovery method of crystalline silicon photovoltaic module

Abstract

The invention discloses a separating device. The separating device is used for separating mixed particles of a smashed and screened photovoltaic module; the separating device comprises a collecting box, a blower device and a storage hopper, wherein the collecting box is provided with an unenclosed end, the blower device is arranged at the unenclosed end of the collecting box, and the storage hopper is arranged at the upper end of the blower device; the blower device is used for producing airflow towards a direction in which the collecting box is arranged, so that the mixed particles in the storage hopper are separated and fall in the different positions of the collection box in the falling process through the airflow of the blower device. The invention further discloses a method for separating the mixed particles of the photovoltaic module by using the separating device. According to the separating device and a recovery method of the crystalline silicon photovoltaic module, the separating device is simple in structure and easy to operate; main materials in the smashed photovoltaic module can be effectively separated; the technical problem that powder is hard to recover by adoptinga physical separating method is solved; the recovery rate of the photovoltaic module is effectively increased; and energy consumption is low, and secondary pollution to the environment cannot be caused.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module recycling, in particular to a separation device and a method for recycling crystalline silicon photovoltaic modules. Background technique [0002] Photovoltaic modules are devices that convert solar energy into electrical energy. The working environment is an exposed outdoor environment. The use of photovoltaic modules has a certain life span, and the general requirement is 25 years. Most of the valuable resources such as silicon, silver, and glass in photovoltaic modules can be recycled and reused through recycling, reducing the exploitation of primary resources and reducing the energy consumption of resource extraction, thereby reducing the impact and damage of the ecological environment. With the increasing installed capacity of photovoltaic power plants around the world, the recycling of photovoltaic modules after failure has become an important issue. [0003] The cohesive force ...

AI Technical Summary

Problems solved by technology

[0007] Each part of the component crushed by the physical method can produce some large broken particles and powders. The large particles can be directly distinguished after being sieved, but it is difficult to separate the powder after sieving, and may be directly discarded, resulting in The waste of resources, therefore, how to separate the sieved powder has become the key point in the physical separation method, and also the key point to achieve low energy consumption, no pollution, and high recovery
