Abstract

The invention discloses a microwave chlorination indium-extraction device for a waste liquid crystal display panel. The device comprises a microwave heating device composed of a microwave generator, amicrowave heating cavity, a microwave communication pipe, an electronic control panel and the like, a quartz reaction device composed of a quartz reaction pipe, a material crucible, a quartz sand core layer and a ground glass sealing plug, a condensation recovery device composed of a quartz condensation pipe, a condensation water pipe and a circulation water pump, and a vacuum device composed ofa vacuum pipeline, activated carbon adsorption equipment and a diaphragm vacuum pump. According to the device disclosed by the invention, chlorination recovery is carried out on indium material in thewaste liquid crystal display panel by taking microwave as heating means, so that high energy utilization efficiency and shadow-free effect are achieved, the heating effect is improved, and the recovery cost and difficulty are lowered; and the device disclosed by the invention is simple in structure, and capable of realizing long-time safe and stable running, and has the advantages of resourcefuland harmless treatment.

Description

technical field [0001] The present invention relates to the technical field of recycling waste liquid crystal panels, in particular to a device for heating waste liquid crystal panel powder and other auxiliary materials with microwaves, and chlorinating and recovering indium materials in waste liquid crystal panels. Background technique [0002] Due to its dual nature (resource and hazard), electronic waste has become a hot spot and difficulty in the safe disposal of solid waste. Some of the resources of electronic waste come from common metals and precious rare metals with high added value. With the increase of scrapped electronic products in the country, and the difficulty in handling electronic waste, the recycling rate is not high, and a large number of precious metals are contained. E-waste has not been effectively recycled. [0003] Since the United States released the world's first liquid crystal display device in 1968, the development of liquid crystal display has a...
