Intelligent: tank liquid life > 12 months (with EDI regeneration system), support IoT remote monitoring
2. Selection and use points
Industry adaptation: Automotive industry: fully enclosed tank + automatic conveying system for driving
Hardware: choose compact tank (minimum capacity 5m³) + Manual hanger
Supporting requirements: Pure water system: water resistivity ≥ 15MΩ·cm (RO+EDI device required)
Power configuration: Three-phase 380V±10%, independent grounding system recommended
Maintenance recommendations: Check tank parameters (solid content/ash content/MEQ value) monthly
Replace ultrafiltration membrane every six months, and acid wash and regenerate anode plates every year
Note: It is recommended to add an online membrane thickness detector (±1μm accuracy) and a tank automatic balance system (to reduce manual intervention)
Main structures and components:
1. Core structure
1. Main tank system
Material: 316L stainless steel or PP lining (acid and alkali resistant, electrochemical corrosion resistant)
Capacity: customized according to workpiece size (typical capacity 10-50m³), including overflow weir design (liquid level fluctuation ≤±2mm)
Insulation design: The insulation resistance between the tank and the ground is ≥10MΩ to prevent leakage risk
2. Circulation filtration system
Main circulation pump: magnetic drive non-leakage pump (flow rate 50-300m³/h, head 15-30m)
Filter unit: two-stage bag filter (precision 20μm) + ultrafiltration membrane system (molecular weight cutoff 5000Da)
Temperature control module: titanium tube heat exchanger (temperature control accuracy ±1℃) + Cooling tower linkage
3. Electrode system
Cathode: Workpiece hanger (DC voltage 100-400V adjustable, current density 1-3A/dm²)
Anode: 316L stainless steel plate or titanium-based mixed metal oxide (MMO) coating
Gap adjustment: Servo motor drive, dynamic adjustment of plate spacing (accuracy ±3mm)
