Structure and Working Principle
The cyclone grit chamber features a conical-bottom circular tank equipped with a rotating paddle separator. Wastewater enters tangentially and follows a 270-degree rotational path (clockwise from top view) before exiting through the discharge channel.
The tangential inflow creates a swirling motion along the inner wall, enhanced by the paddle agitation. This generates an axial vortex that accelerates the settling of sand particles while effectively separating organic matter. The flow velocity increases toward the center, guiding settled sand in a spiral trajectory to the central hopper. Organic materials rise centrally and are discharged with the effluent. Sand collected at the bottom is extracted via a lifting mechanism (airlift or pump) and directed to a sand-water separator, with separated wastewater returning to the screen channel.
Key Features
Stable Performance: Consistent desanding efficiency despite flow variations. Compact design with easy operation and maintenance.
Flexible Sand Extraction: Optional airlift (better treatment effect) or pump lift (lower cost).
High Efficiency: Removes >85% of particles ≥0.2mm.
Material Options: Steel construction for Q <1080 m³/h; concrete structure for higher capacities.
Automated Control: PLC-controlled sand washing and discharge cycles for reliable operation.
Ease of Operation: Local and remote control capabilities for user convenience.
