Stainless Steel Sand Separator

Hydrocyclone Sand Separator Working Principle

The Cyclone Sand Separator operates using the principle of centrifugal separation to remove sand. Due to the inlet pipe being installed at an eccentric position within the cylinder, as water passes through the inlet pipe of the separator, it first forms an oblique downward peripheral flow along the cylinder's peripheral tangent. The water rotates downward, and upon reaching a certain part of the cone, it changes direction to rotate upward along the cylinder's axis and is discharged through the outlet pipe. Impurities, under the influence of the centrifugal force of the fluid's inertia and its own gravity, fall along the cone wall into the lower conical sedimentation basin of the equipment. A component at the lower part of the cone prevents the rise of debris. When the accumulated debris in the sedimentation basin reaches a certain level, simply by opening the manual butterfly valve, the debris can be flushed out of the Cyclone Sand Separator by the water flow.

The Cyclone Sand Separator operates based on the principles of centrifugal sedimentation and density differences. As water flows tangentially into the unit through the sand removal inlet under certain pressure, it generates a strong rotational motion. Due to the different densities of sand and water, under the combined effects of centrifugal force, centripetal force, buoyancy, and fluid drag, the less dense water rises and is discharged through the outlet, while the denser sand particles are discharged through the bottom drain of the unit, thereby achieving the sand removal goal.

Hydrocyclone Sand Separator Working Principle

When water flows tangentially into the equipment at a certain pressure from the sand removal inlet, it generates a strong rotational movement. Due to the different densities of sand and water, the low-density water rises and is discharged through the outlet, while the high-density sand particles are discharged through the bottom waste outlet of the equipment, achieving the sand removal purpose. It features high sand removal rate, space-saving installation, low leakage rate for individual small solids, and stable working conditions.

The Cyclone Sand Separator operates based on the principles of centrifugal sedimentation and density difference. When water flows tangentially into the equipment through the sand removal inlet under certain pressure, it generates a strong rotational motion. Due to the difference in density between sand and water, the combined actions of centrifugal force, centripetal force, buoyancy, and fluid drag cause the lower-density water to rise and exit through the outlet, while the higher-density sand particles are discharged from the bottom waste outlet of the equipment, thereby achieving the sand removal purpose.

Under certain scope and conditions, the higher the water pressure of the desander, the higher the desanding rate, and it can be used in parallel with multiple units.

Process Flow: Raw Water - Cyclone Sand Removal - Filtration - Storage Pond - User. The cyclone sand removal unit operates based on the principles of centrifugal sedimentation and density difference. When water flows into the unit tangentially at a certain pressure through the sand removal inlet, it generates a strong rotational motion. Due to the difference in density between sand and water, the low-density clear water rises under the action of centrifugal force, centripetal buoyancy, and fluid drag, and is discharged through the overflow outlet. The high-density sand is discharged from the bottom sand outlet, thereby achieving the sand removal purpose. Within a certain range and under certain conditions, the higher the water pressure entering the sand removal unit, the higher the sand removal rate, and multiple units can be used in parallel.

Vortex Sand Separator Features

1. Simple structure, easy operation, and safe and reliable use; almost no maintenance required.

2. Compared to sand removal equipment such as expanded pipes and buffer boxes, it offers advantages such as a smaller size, higher processing capacity, and space-saving on-site.

3. Removes sand particles from water during continuous water supply.

4. Eliminates the issue of secondary water pollution that occurs with other sand removal methods, featuring high sand removal efficiency.

Selection Notice

Selecting a vortex de-sander requires consideration of factors such as water volume to be treated, external pipe diameter, pipeline working pressure, raw water quality, and the required water quality after treatment. Generally, when choosing a vortex de-sander, it is recommended to opt for a larger model device, provided the flow rate is met, and to use multiple devices in parallel within the system to achieve better solid-liquid separation.

Centrifugal sand separator installation注意事项

1. The swirl sand separators should be installed on the main pipeline of the water supply network and securely mounted on a base. A bypass should be added between the inlet and outlet pipes.

2. To ensure a smooth water flow into the equipment, a straight-through pipe of the same diameter as the inlet should be installed before the water inlet, with a length of 10-15 times the diameter of the inlet.

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

4. During normal operation, the inlet and outlet valves must be open, while the drain valve and bypass valve should be closed.

5. Regularly drain and remove silt and impurities based on the sand content of the source water. Open the drain valve during discharge until clear water flows out, as the drainage process will not affect the normal water supply of the system.

6. After waste discharge is complete, close the discharge valve.

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