working principle
Gas-Liquid Emulsification Technology: Some new neutralization tanks use circulating pumps and liquid-gas jet pumps to form microbubble mixing, improving oxygen utilization and accelerating the dissolution process (e.g., copper dissolution speed can be increased by 4-7 times).
Automatic Control: The pH value is monitored in real time through a computer system, and a feedforward-feedback composite control strategy (such as segmented variable gain PID) is adopted to ensure reaction stability and accuracy.
Application Areas
Electroplating and Metal Treatment
Used to neutralize residual acidic substances after pickling and passivation to prevent equipment corrosion.
Hydrometallurgy
In ore slurry treatment, neutralizing and acidifying the slurry helps recover metals, and controlling pH levels to prevent environmental pollution.
Chemical Industry and Environmental Protection
Treating industrial wastewater (such as electroplating wastewater and pharmaceutical wastewater) to achieve harmless discharge; dissolving copper materials in copper sulfate production to improve production efficiency.
Semiconductor and Pharmaceutical Industries
High-precision pH control in cleaning systems ensures process purity.
