The Application Principle of Cyclone Desander and its Application Advantages in Water Desandering and Separation

The cyclone desander is based on the principle of centrifugal sedimentation and density difference. When the water flow enters the equipment tangentially from the inlet of the desander under a certain pressure, it will produce strong rotational motion. Due to the different densities of sand and water, under the centrifugal force , centripetal buoyancy, and fluid drag due to different forces, the low-density clean water rises and is discharged from the overflow port, and the high-density sand is discharged from the bottom sand discharge port, thereby achieving the purpose of sand removal. Within a certain range and conditions, the greater the water inlet pressure of the desander, the higher the sand removal rate, and multiple units can be used in parallel.

Features of Cyclone Desander

1. Simple structure, low cost, easy to install and operate, safe and reliable to use, and requires almost no maintenance.

2. Compared with other equipment, it has small size, large processing capacity and saves on-site space.

3. It has high decontamination efficiency, small resistance coefficient, large flow rate, convenient decontamination and reliable operation.

4. The dirt can be cleaned during operation, that is, there is no need to shut down the water pump.

The cyclone desander is made based on the screening principle of solid particles in the fluid rotating in the desander. It integrates cyclone and filtration to achieve sand removal, turbidity reduction, solid-liquid separation and other effects in the field of water treatment. Significantly. Widely used in water source heat pumps, water treatment, food, medicine and other industrial sectors. Sand removal from river water and well water, coal washing water, industrial mineral processing, solid-liquid separation, liquid degassing and separation of immiscible liquids.

1. The cyclone desander should be installed on the main pipe of the water supply network and fixed on the base. A bypass should be added between the inlet and outlet pipes.

2. In order to ensure a stable water flow, a straight pipe with the same diameter as the water inlet should be installed in front of the equipment's water inlet. The length is equivalent to 10-15 times the diameter of the water inlet.

3. Sufficient maintenance space should be reserved around the equipment during installation.

4. During normal operation, the inlet and outlet valves need to be opened, and the drain valve and bypass valve need to be closed.

5. Regularly discharge sand and decontamination according to the sand content of the source water. When discharging sewage, open the sewage valve until clean water flows out. The sewage discharge process will not affect the normal water use of the system.

6. After the sewage discharge is completed, close the sewage valve.

7. If the sand discharge pressure is insufficient, close the valve at the water outlet.
