Cyclone Desander
The cyclone desander is a modern separation device designed based on the principle of filtering solid particles from fluid through rotational motion within the desander, enhanced by additional filtration measures. It integrates cyclone and filtration. It has significant effects in desanding, turbidity reduction, solid-liquid separation, etc. in the field of water treatment. It is widely used in water treatment, river water, well water desanding, coal washing water, industrial mineral processing, solid-liquid separation, etc.
Working Principle of Cyclone Desander
The working principle of cyclone desander is to separate the solid particles suspended in the liquid by the effect of cyclone. Solid particles settle at the bottom of the equipment and are expelled through the drainage outlet below. Clean water will flow from the middle guide pipe through the outlet to the subsequent pipeline.
When water flows into the desander tangentially from the water inlet under a certain pressure, a strong rotation motion is generated, and the water swirls downward. Due to the different densities of sand and water, the water with low density rises under the action of centrifugal force, centripetal force, buoyancy, and fluid electricity, and is discharged from the outlet. The sand particles with high density fall into the conical hopper at the bottom of the equipment along the cone wall under the action of fluid inertia centrifugal force and their own gravity. When the debris in the hopper reaches a certain level, it can be flushed out with the water flow by opening the manual butterfly valve.
Key Points for Model Selection
- Flow rate: Select the appropriate specification according to the amount of water to be processed.
- Water inlet pressure: The equipment needs a certain pressure to form an effective rotational flow.
- Separation particle size: Understand the particle size range of the target solid particles to ensure that the equipment can effectively separate.
- Material: Select materials with excellent corrosion resistance, such as stainless steel, according to the use environment.

Advantages of Cyclone Desander
- Simple operation, no filter cloth or other filter materials are required, so there will be no clogging problem. It is safe and reliable to use, and almost no maintenance is required.
- It has a large processing capacity. Compared to other desanding equipment, it offers the benefits of compact size, high processing capacity, and efficient use of on-site space.
- The internal structure design is scientific and reasonable, which simplifies the process flow, increases efficiency, reduces labor intensity, and saves manpower.
- The desander has high efficiency and can remove sand particles in the water during uninterrupted water supply, and also avoids the phenomenon of secondary water pollution in other desander methods.
- The pressure loss is stable and will not change with changes in water quality and operation time.
Maintenance and Care Precautions
- Regularly inspect the sand outlet to ensure it remains unobstructed.
- Clean the interior of the equipment based on usage frequency and water quality to avoid excessive sand buildup.
- Check whether the water inlet pressure is within the recommended range to ensure the normal operation of the equipment.
