cyanide degradation rate ≥99.9% (with oxidant)
Reaction time: 2-4h (adjusted according to concentration)
5. Safety and environmental
protection explosion-proof level: Ex dⅡ BT4 (optional)
Waste gas
treatment: The top exhaust port is connected to the alkali liquid absorption tower (to treat HCN)
Protection level: IP65 (outdoor dust and water proof)
6. Equipment size and weight
| parameter | value |
| Overall height | ≈ 8500mm (including motor) |
| diameter | 6500mm |
| weight | 18-25t |
7. Selection recommendations
1. Highly corrosive conditions (such as cyanide-containing wastewater): choose titanium alloy stirring system + PTFE lining.
2. High temperature detoxification (≥80℃): need to be equipped with high temperature resistant seal and cooling jacket.
3.Maintenance points:
Check the seal and stirring shaft vibration every week
and calibrate the monitoring instrument every quarter
.(Note: The actual selection requires the medium composition, concentration and treatment scale and other parameters.)
