Product Description
XXLC Type Vortex Desander
XXLC type vortex desanders are generally used in fine-screen sedimentation tanks (bell-type sedimentation tanks) of wastewater treatment plants to separate larger inorganic particles from wastewater.
Generally, airlift pumps or pumps are used for sand removal.
The vortex desander integrates multiple functions such as sand sedimentation, washing, and discharge. It features low energy consumption, small footprint, cost savings, advanced technology, and easy maintenance, placing it at the forefront of domestic technology and making it a viable alternative to similar foreign products.
Its features:
Reasonable and compact structural design, small footprint, low investment, low failure rate, and convenient maintenance and use;
Sand sedimentation effect is minimally affected by water volume changes;
Good sand-water separation effect, low water content in separated sand, low organic matter content, easy to transport;
The system uses PLC automatic control of sand washing and discharge cycles, ensuring safe and reliable operation;
Convenient operation, simple maintenance, and long service life;
Minimal impact on the surrounding environment and good hygiene conditions.
Working principle
Wastewater enters the vortex desander tangentially at a certain flow rate. Under the action of centrifugal force and gravity, sand particles rotate along the cylindrical wall in a spiral, accelerating downwards. The wastewater, through the rotation of the inclined blade, throws the sand particles towards the wall, which then slide down the inclined wall into the sand collection hopper.
The settled sand in the sand collection area is forcefully washed by an air pump, separating organic matter from the sand particles. The organic matter returns to the wastewater, and the sand particles are lifted by a blower. The discharged sand-water mixture is further separated by a sand-water separator before being discharged, thus separating the sand particles from the wastewater and reducing the sand content in the wastewater.
