System compose
The system is mainly comprise of electrolysis system, storage circulation system, chlorine absorption system, internal circulation system, automatic control system, etc.
Process principle
IT was mainly based on the technology of the direct electrolysis of copper chloride, let the acid etching waste liquid introduced into the electrolysis equipment and divide into positive and negative electrodes for electrolysis. During the electrolysis process, chlorine gas will be produced by anode which will be sealed extraction, dissolution and absorption, and copper plate will be produced by cathode electrolysis. After adjusting ORP, acidity and adding additives, regeneration liquid will be reused in acid etching system.

Recovery and utilization of chlorine
Main features
1.copper extraction from Acid etching, efficient recovery, minimize the pressure of discharge, the rate of copper recovery is more than 99%,it also improve economy greatly value and achieve to energy conservation and emission reduction.
2.The chlorine absorption equipment is designed independently and has highly efficient; the liquid of anion and anode are reused separately, and the reused liquid has high ORP and high acidity, The amount of oxidant and hydrochloric acid which need to be added are greatly reduced so that it can save costs.
3.The design of chlorine tail gas treatments is unique and it is the best scheme to eliminate potential safety hazards.
4.The etching speed of reuse solution is stable, and the change of speed is less than 5% before reuse.
5. The equipment is solid and durable, using high-quality materials, safe and reliable, and have high degree of automation.
