Tubular Electrolytic Cell for Cyclone Electrowinning Technology

​​​​​​​Tubular Electrolytic Cell for Cyclone Electrowinning Technology

In cyclone electrowinning technology, the tubular electrolytic cell enhances mass transfer through a high-speed swirling flow field, enabling efficient electrowinning extraction of metal ions at low concentrations. Our Tubular Electrolytic Cell for Cyclone Electrowinning Technology at Baoji City ShenAo Metal Materials Co., Ltd. is designed specifically for applications in hydrometallurgy, metal recovery, and valuable metal extraction from industrial wastewater. It uses Grade 1 or Grade 2 pure titanium for the cell body and electrode substrates, with an iridium-tantalum mixed metal oxide catalytic coating on the anode surface. The tubular coaxial structure, combined with an optimized flow channel design, creates a high-speed swirling flow between the anode and cathode, effectively reducing the diffusion layer thickness and increasing the limiting current density. The anode coating maintains stable oxygen evolution activity and chemical stability in acidic electrolytes, minimizing the risk of metal ion dissolution. The complete electrolytic cell is suitable for the cyclone electrowinning of copper, nickel, cobalt, silver, and other metals, providing a reliable equipment-level solution for your metal recovery and resource utilization applications.

Why Choose Our Titanium Anodes?

• Cyclone Design for Enhanced Mass Transfer and Deposition Efficiency
  The electrolyte passes through the annular gap of the tubular electrolytic cell at high velocity in a cyclone flow state, creating strong liquid turbulence at the electrode surface. This forced convection significantly reduces the diffusion layer thickness, alleviating concentration polarization under high current density conditions and enabling metal ions to deposit uniformly on the cathode surface at a faster rate. Compared to conventional plate-type electrolytic cells, the cyclone tubular structure demonstrates better mass transfer efficiency and current efficiency when processing low-concentration metal solutions.
• Compact Structure for Reduced Equipment Footprint
  The concentric tubular layout integrates the anode and cathode into a compact, self-contained electrolysis unit, with effective electrode area per unit far exceeding that of plate-type cells occupying the same footprint. Multiple tubular cells can be flexibly combined in series or parallel configurations and rapidly scaled according to production capacity requirements, making them particularly suitable for production line upgrades with limited space and modular new-build projects.
• Enclosed Operation for Improved Workplace Environment
  Cyclone electrowinning takes place within a sealed tubular chamber, allowing acid mist, gases, and heat generated during electrolysis to be collected and treated through centralized piping. This design contributes to improved workshop air quality, reduces acid mist corrosion on surrounding equipment and building structures, and lowers the risk of operator exposure to hazardous gases.
• Modular Design for Easy Maintenance and Expansion
  Each tubular electrolytic cell operates as an independent module that can be individually disassembled, inspected, or replaced without affecting the continuous operation of other units. The anode titanium tube can undergo recoating treatment when the coating reaches the end of its service life, and the cathode base tube can be reused, helping you reduce equipment operation and maintenance costs over the full lifecycle.

Real-World Applications

• Hydrometallurgy and Metal Recovery: Used for the efficient electrowinning of non-ferrous metals such as copper, nickel, cobalt, and zinc from leach solutions, covering mine hydrometallurgy, metal recovery from electroplating waste solutions, and the electrolytic extraction of precious metals from electronic waste.
• Industrial Wastewater Treatment: Used for the electrolytic recovery of heavy metal-containing industrial wastewater, removing heavy metal ions such as copper, nickel, and chromium from wastewater while achieving resource recovery of valuable metals, applicable to wastewater treatment in the electroplating, PCB manufacturing, and metallurgical industries.
• Electroplating and Surface Treatment: Used for online recovery of metal-containing waste liquids such as rinse water and aged plating baths on electroplating lines, reducing metal ions to high-purity metal products through cyclone electrowinning, thereby lowering metal raw material losses and wastewater treatment loads for electroplating production lines.
• Chlor-Alkali and Halogen Chemical Production: Used for deep purification after calcium and magnesium impurity removal in brine refining for the chlor-alkali industry, or for the electrolytic production of halogen chemicals such as chlorates and perchlorates, utilizing the efficient mass transfer characteristics of tubular electrolytic cells to enhance current efficiency.

Frequently Asked Questions

Q: What is the core difference between cyclone tubular electrolytic cells and conventional plate-type cells?
A: The core difference lies in the electrolyte flow pattern and mass transfer efficiency. In conventional plate-type cells, the electrolyte typically flows slowly between electrode plates in a laminar state, resulting in a thicker diffusion layer and noticeable concentration polarization. The cyclone tubular cell creates strong liquid turbulence at the electrode surface through forced cyclone flow, significantly reducing the diffusion layer thickness and thus enabling operation at higher current densities, making it particularly suitable for processing low-concentration metal solutions. Additionally, the tubular structure operates in an enclosed manner, with better acid mist emission control than open plate-type cells.

Q: How do I select the anode coating type based on the process solution?
A: It primarily depends on the acidity, anion type, and oxygen evolution proportion of the solution. Sulfate systems typically use iridium-tantalum coatings, which remain stable under strong acid and high oxygen evolution conditions. Chloride systems can use ruthenium-iridium coatings to balance chlorine and oxygen evolution activity. Solutions containing organics or special additives require coating compatibility assessment. You can provide your solution composition and operating parameters, and our engineers will recommend a matched coating solution.

Q: How can the production capacity of tubular electrolytic cells be scaled?
A: Tubular electrolytic cells adopt a modular design, with each unit operating as an independent electrolysis cell. Capacity expansion is flexible: first, by increasing the number of parallel branches while maintaining constant flow per tube; second, by increasing the number of tubes in series per group to improve single-pass metal recovery; third, through hybrid configurations tailored to site conditions. We can provide a recommended tube arrangement plan and equipment quantity based on your target processing capacity and metal concentration.

Q: How should anode tubes be handled when the coating reaches the end of its service life?
A: The titanium tube substrate remains stable in acidic electrolytes. The old coating can be chemically stripped, and once the substrate passes inspection, it can be recoated. We offer a full-service process including incoming inspection of used anode tubes, coating stripping, substrate treatment, and recoating, restoring performance to new anode tube levels. The cathode base tube can similarly be reused after cleaning and surface treatment.
