Cyclone Separator

Overview

The cyclone separator is a high-efficiency gas-solid-liquid separation equipment developed on the basis of cyclone separators. It is widely applicable for high-efficiency separation of gas-liquid and gas-solid-liquid mixtures.

Working Principle

The cyclone separator organically integrates technologies such as centrifugal separation and filtration separation, avoiding liquid film shearing, re-atomization, liquid entrainment, entrainment, suction and secondary fragmentation. During separation, gas enters the cyclone under a certain pressure, rotates and flows axially downward. Under centrifugal force, most liquid and solid particles are thrown toward the wall at the lower part of the cylinder. As gas flows out of the cyclone, the flow cross-section gradually expands and the flow velocity decreases. Liquids and solids are discharged along the vessel wall to realize gas-liquid or gas-solid separation.

After separation, the gas flows into the outlet pipe and passes through a mist eliminator for secondary separation. Small entrained liquid droplets in the gas coalesce into large droplets, which fall by gravity and flow through the guide pipe into the liquid accumulation chamber. Finally, separated solid particles and liquid are discharged via the drain port, and the treated gas exits through the gas outlet.

Features of Cyclone Separator

(1) High separation efficiency for liquid and solid particles. Through numerical shaping of the flow channel, the cyclone separator achieves more regular fluid flow inside the separation elements, reaching an optimal state for gas-liquid and gas-solid separation. The shaping of fluid flow in separation elements eliminates adverse effects such as liquid entrainment, shear fragmentation, gas flow atomization and re-entrainment, ensuring stable separation efficiency of the equipment.

(2) High flexibility with a flow fluctuation range of 40–120%, adapting to particle distribution conditions of inlet gas. Adopting special separation elements, the cyclone separator maintains highly regular fluid flow and favorable flow patterns even under low gas flow rates and low gas velocities, securing high separation efficiency across a wide flow range.

(3) Low pressure drop and large processing capacity. Optimized with preferred curved profiles for separation elements, the core components can be customized for different flow rates and working conditions. This ensures the cyclone separator features low pressure drop (5–30 kPa) and large throughput.
