High-Efficiency Rotary Distillation Unit

The equipment operates on the following principles:
(1) Utilizing centrifugal force to disperse the liquid before it contacts the gas, ensuring more thorough interaction than direct liquid-gas contact. This significantly increases the gas-liquid interfacial contact area and enhances mass/heat transfer rates and efficiency, thereby drastically reducing the equipment size.
(2) A rotor with a specially designed structure rotates at high speed within the housing. The gas phase enters the equipment through the gas inlet, flows from the rotor’s outer edge into its interior, while the liquid phase enters the rotor’s center via the liquid inlet. Inside the rotor, the two phases form an extremely high-specific-surface-area gas-liquid interface that continuously renews itself, achieving high-efficiency mass and heat transfer. Ultimately, the gas phase exits the housing through the gas outlet and is condensed in a condenser, while the liquid phase is collected within the housing and discharged through the liquid outlet.

	← Gas phase
	→ Liquid phase
	By replacing the gravitational field with a centrifugal force field, the gas-liquid contact and transfer processes are intensified, thus significantly reducing equipment volume.
