Abstract

The invention discloses pyrolysis equipment and a battery pack heat treatment method. The pyrolysis equipment and the battery pack heat treatment method are used for carrying out pyrolysis treatment on a packaging material of a battery pack. The pyrolysis equipment comprises a pyrolysis furnace, a conveying device, a heating device and a plurality of air interchangers. The conveying device includes a conveying belt for conveying the battery pack, and the conveying belt extends from an inlet of the pyrolysis furnace to an outlet of the pyrolysis furnace; the heating device comprises a heating pipe and a heating cover, wherein the heating pipe is used for heating the battery pack on the conveying belt, and the heating cover covers the side, away from the conveying belt, of the heating pipe;and the air interchangers are arranged at intervals along the conveying direction of the conveying belt, each air interchanger is arranged to be capable of introducing nitrogen or air to the battery pack so as to generate a pyrolysis reaction with the packaging material of the battery pack, and leading out exhaust gas generated by the pyrolysis reaction of the packaging material in the heating cover. According to the technical scheme, the packaging material of the battery pack is removed in a pyrolysis mode, the time consumption is short, and the recovery processing efficiency is high.

Description

technical field [0001] The invention belongs to the field of environmental protection technology for recycling waste materials, and in particular relates to a pyrolysis device and a heat treatment method for battery components. Background technique [0002] EVA (copolymer of ethylene and vinyl acetate) is currently the most commonly used material in the solar cell encapsulation process, mainly by adding various UV absorbers, UV stabilizers, antioxidants and crosslinking agents to the EVA base material. Made with additives. According to the different crosslinking agents added, EVA is divided into two types: conventional type and fast curing type (also known as fast curing type). The main difference is that the time required for curing is different. EVA will undergo a cross-linking reaction during the curing process to form a Lanwei network structure, which plays a good role in sealing the solar cell. [0003] However, there are few studies on how to remove EVA in the recycl...
