Pyrolysis device

Abstract

The invention provides a pyrolysis device. The pyrolysis device comprises a conveying system, a preheating box, a high temperature decomposition box, a cooling box and loading devices; the preheatingbox, the high temperature decomposition box and the cooling box communicate in sequence and are all arranged on the conveying system; the conveying system can convey the loading devices to enter the preheating box, the high temperature decomposition box and the cooling box in sequence; the loading devices are used for bearing pyrolyzed pieces; a heating piece is arranged in each of the preheatingbox, the high temperature decomposition box and the cooling box; an openable / closable airtight door is arranged at each of an inlet of the preheating box, the position between the preheating box and the high temperature decomposition box, and an outlet of the cooling box; and the airtight door is used for closing the preheating box, the high temperature decomposition box and the cooling box. Through the scheme, the overflow of gases in various areas is effectively partitioned by matching separated heating areas and the airtight doors; the hazard of the overflow of high temperature toxic exhaust gas is prevented; continuous mass production can be realized; and moreover, the production capacity can be adjusted by adjusting the length of each heating area.

Description

technical field [0001] The invention relates to the field of crystalline silicon photovoltaic modules, in particular to a pyrolysis device. Background technique [0002] Crystalline silicon photovoltaic modules are the mainstream products in the photovoltaic market at present. The service life of photovoltaic modules is generally 20-30 years. At present, the modules put into use around 2000 have begun to enter the retirement period. At the same time, due to various quality and use reasons, there are also quite large quantities. There are obsolete components, and as time goes by, the number of decommissioned components will enter an explosive period. A large number of waste components need to be harmlessly treated and resource recycled. [0003] Crystalline silicon photovoltaic modules are generally composed of crystalline silicon solar cells, ribbons, EVA, backplanes, glass, junction boxes, aluminum frames and other materials and components, the main part of which is compos...
