Basicity Etching direct electrolytic recycling system

System diagram: 

PRINCIPLE:

The principle of alkaline etching by direct electrolysis. Through direct electrolysis technology, the copper ions in the waste liquid are precipitated on the cathode plate. After electrolysis, the regeneration liquid is returned to the production line by supplementing ammonia and etched salt and then returned to the production line for recycling, so as to realize the recycling of alkaline etched waste liquid and the recovery of copper.

Process characteristics:

1. The etching process does not need to purchase the new etching liquid, and the etching waste liquid can be completely recycled, saving material consumption and reducing the production cost;
2. The recovery rate of etching waste liquid copper is> 99%, the purity of the output copper is over 99.9%, and the price is high;
3. The equipment process is simple and easy to operate;
4. The installation equipment site covers a small area;
5. Realize clean production, energy saving, and emission reduction, basically zero emissions, and reduce the environmental protection pressure in factories.
