Concept cyclone is a common separation and classification device, which works by centrifugal sedimentation. When the two-phase (or three-phase) mixture is introduced into the cyclone separator tangentially from the periphery of the cyclone separator under a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Due to the difference of particle size (or density difference) between coarse particles (or heavy phase) and fine particles (or light phase), they are affected by centrifugal force, centripetal buoyancy and fluid resistance, and undergo centrifugal sedimentation. Some coarse particles (or dense phase) pass through Hydrocyclone Most of the fine particles (or light phase) are discharged through the overflow pipe to achieve the purpose of separation and classification.
How it works Hydrocyclone Under the action of centrifugal force, the liquid-liquid, liquid-solid and liquid-gas mixtures can be separated into a certain density difference. Under a certain pressure, the mixture is introduced tangentially into the cyclone separator to generate a high-speed rotating flow field in a cylindrical chamber. The component moves down the inner wall of the vortex and moves down the inner wall of the vortex to form a separation along the bottom of the inner wall of the vortex.
Operation mode. Before starting the test, make sure that all connection points of the cyclone unit are tightened and all residues in the pipe and unit cabinet are removed to avoid leakage and blockage after driving. Ensure that the swirl valve put into operation is fully opened.
2. The valve can be fully opened (e.g. operating Hydrocyclone )Or completely closed (e.g. stand-by cyclone), but not allowed to be in a half open state (i.e., the valve cannot be used to control flow).
3. If possible, please test with water first. The feed of cyclone separator can be supplied by pump or high tank. If the pump matches the cyclone throughput, the meter shows a constant reading. To ensure that the pressure gauge reading does not fluctuate, check the cause for obvious fluctuations. The equipment needs to work under the pressure not higher than 0.3MPa.
4. When the equipment runs smoothly under normal pressure, check the connection point for leakage and take remedial measures if necessary.
5. Check that debris enters the cyclone Hydrocyclone Caused by the blockage. The flow of sand and gravel will be reduced Hydrocyclone The sand clogging will reduce or even close the gravel flow, sometimes causing serious vibration. In case of blockage, the cyclone feed valve should be closed in time to prevent blockage. In order to prevent blockage, equipment (such as chip screen) can be added into the feeding bowl of hydrocyclone group to prevent coarse material and debris. When parking, the feeding pool should be emptied in time to avoid rainfall. Drive again. Too high concentration can lead to blockage accident.
