| discharge cleaning | Rotating spray ball (CIP cleaning) |
| system level monitoring | Radar level gauge (± 1mm accuracy) |
5.Special design
Anti-crystallization measures:
Tank electric heating (50W/m, maintained at 40-60℃)
Side wall vibrator (to prevent NCN crystal deposition)
Anti-corrosion reinforcement: Weld pickling passivation treatment Cathodic protection
(optional)
6.Environmental adaptation
Explosion-proof level: Ex dⅡ BT4 (overall explosion-proof design)
Seismic level: Level 8 (GB 50011-2010)
Protection level: IP65(outdoor type)
7.Selection recommendations
1. High concentration cyanide (≥30%): PTFE lining + nitrogen blanketing system must be selected
2. Mobile storage tank:
Must comply with GB 18564.1 standard and be equipped with wave-proof plates
3.Maintenance cycle:
Monthly: Leakage test
Annual: Wall thickness ultrasonic test
(Note: The actual selection requires the specific composition, concentration and ambient temperature
