Problems solved by technology

The traditional air supply device is a simple air pipe, which cannot discharge the air evenly and efficiently into the reaction solution
[0005] At the same time, when the reaction tank and the oxidation tank are performing a large amount of reaction recovery, a large amount of residue will be deposited on the bottom of the reaction tank and the oxidation tank, which cannot be eliminated.

Description

technical field [0001] The invention relates to the field of recycling waste copper clad laminates, in particular to a reaction recovery system for waste copper clad laminates. Background technique [0002] Copper-clad laminate is an electronic circuit board, which is made of copper substrate and insulating board. With the rapid development of the electronics industry, waste copper-clad laminates have become a large amount of industrial waste, and these waste copper-clad laminates are usually crushed or burned to remove the insulating board and recover copper. Combustion treatment will cause serious pollution to the environment. However, the crushing treatment method not only cannot effectively recycle the waste copper-clad laminates, but also requires a lot of cost. Therefore, there is a production method of utilizing waste copper clad laminates to regenerate copper sulfate. The production method solves the problem of dealing with a wide range of waste copper clad lamina...
