Circuit board wire crushing and cracking process

Abstract

The invention discloses a circuit board wire crushing and cracking process. The circuit board wire crushing and cracking process comprises the following steps that a waste circuit board wire is crushed, heated for detinning to discharge molten tin and generate waste gas, and the rest is taken as waste materials; the waste gas and the waste materials are fed into an anaerobic cracking furnace to be cracked and gasified to generate products including combustible gas, carbon, metal and glass fibers, then the combustible gas is subjected to heat preservation, dust is filtered out, the combustible gas is fed into a combustible gas pressurization supply system and enters a combustion system to be combusted, and the rest is taken as cracked waste materials; the cracked waste materials are cooled, smashed and fed into a material collector, raised dust is collected through a dust collector, then carbon powder in the material collector is screened out through a wind power screening method, the carbon powder and the raised dust collected by the dust collector are combined, and then magnetic waste materials, non-magnetic metal waste materials and glass fiber waste materials are separated out from the cracked waste materials after the carbon powder is screened out through magnetic separation and winnowing. According to the circuit board wire crushing and cracking process, defects in the prior art are overcome, and smoke dust and toxic gas are not generated in the treatment process.

Description

technical field [0001] The invention relates to the technical field of circuit board electric wire crushing and cracking, in particular to the circuit board electric wire crushing and cracking process. Background technique [0002] With the popularization of electronic equipment and the continuous expansion of the number of people using electrical equipment, electronic equipment can be seen everywhere in our lives, and has gradually become an inseparable item for people. However, with the rapid development of software and hardware technology, electronic equipment It is also being updated rapidly, making discarded electronic equipment an important part of people's domestic waste today. However, due to the small and numerous parts of electronic equipment, they cannot be treated like conventional large-scale electronic waste, especially the interior of electronic equipment. Due to the large number of electronic components and materials that make up the circuit boards and circui...
