Abstract

The invention discloses a debromination device for non-metallic components of waste circuit boards. Crushing is conducted through a planetary-type ball mill in a high-energy ball-milling method, and compared with a traditional ball-milling technology, as for a planetary-type ball-milling method, the motion rate is high, hard materials can also be fully crushed, the crushing efficiency is high, andnano-grade polymer powder can be obtained. According to the debromination device, a resource recovery process, removing of a bromine-containing fire retardant, treatment of gas contaminants and recovery of bromine resources are combined; and compared with a general physical crushing method for recycling non-metallic particles of the waste circuit boards, the defects that a conventional crusher isadopted to treat nonmetal of the waste circuit boards in China, serious secondary pollution is generated, and later using is not facilitated are overcome, and the debromination device has the advantages that the cost is low, the structure is simple, the environment friendliness effect is achieved, and the non-metallic components in the circuit boards can be recycled in a high-value mode.

Description

technical field [0001] The invention relates to a debromination device, in particular to a debromination device for non-metal components of waste circuit boards. Background technique [0002] In recent years, with the rapid development of the economy and the rapid replacement of household appliances and electronic products, the amount of waste electrical and electronic equipment (WEEE) has also increased. Circuit boards are the core components of various electronic and electrical products. With the mass scrapping of electronic appliances and the scraps generated in the production process, the amount of scrapping is also increasing sharply. The recycling of scrapped circuit boards, namely Waste Printed Circuit Boards (WPCBs), is facing major difficulties. Mainland China needs to dispose of more than 500,000 tons of waste printed circuit boards every year. With the implementation of my country's sustainable development strategy, higher requirements are put forward for enviro...
