Description

TECHNICAL FIELD

[0001] The utility model relates to desulfurization magnesium sulfite slurry cyclone separation technical field especially relates to a kind of desulfurization magnesium sulfite slurry cyclone. BACKGROUND

[0002] Cyclone is a common separation and classification equipment, centrifugal sedimentation principle is often used. When the two-phase mixture to be separated enters cyclone tangentially from the periphery of cyclone at a certain pressure, strong three-dimensional elliptical type strong rotating shear turbulent flow motion is generated. Due to the size difference between coarse particles and fine particles, the centrifugal force, centripetal buoyancy, fluid drag and other sizes are different, affected by centrifugal sedimentation, most of the coarse particles are discharged through the underflow port of cyclone, and most of the fine particles are discharged through the overflow pipe, so as to achieve the purpose of separation and classification.

[0003] The working principle of cyclone is based on the principle of centrifugal sedimentation. When the mixture enters the device tangentially from the cyclone at a certain pressure, a strong rotating flow field is formed inside the cyclone. Under the action of centrifugal force, different components in the mixture will separate according to the difference in density and particle size. The components with higher density move outward under the action of centrifugal force, move downward along the wall, and are discharged through the underflow port. The components with lower density form upward vortex in the central area, and are discharged through the overflow port.
