Working Principle
The liquid flows through the candle element from outside to inside, where suspended particles are captured on the filter surface. When ΔP reaches the preset value, the explosion-proof pneumatic cylinder activates the backwashing process. Clean liquid flows in the reverse direction to remove trapped impurities, which are discharged automatically, restoring filtration performance without interrupting operation.
1. Filtration Stage
Raw Liquid Inlet → Outside → Inside Flow Through Candle Element → Impurities Trapped → Clean Liquid Outlet
↓
2. △P Detection
Impurity Accumulation → Differential Pressure (△P) Increase → Automatic Cleaning Signal
↓
3. Pneumatic Backwashing
Explosion-Proof Pneumatic Cylinder Activated → Reverse Cleaning Flow Inside → Outside → Candle Element Regenerated
↓
4. Impurity Discharge
Contaminants Removed → Drain Outlet Discharge → Filtration Restored
