Rotary distillation machineIt is a new type of distillation equipment. In the hypergravity rotary distillation machine, the liquid phase undergoes multiple processes of dispersion and aggregation. During this process, the liquid is thrown away from the moving circle in concentric circles as extremely fine droplets. Under the action of centrifugal force, the high-speed moving droplets are collided, sheared, and splashed on specific structures inside the equipment, forming a gas-liquid interface with a large specific surface area and constantly updating. After aggregation, it enters the next cycle.

In the device, the gas-liquid two-phase flow in the rotor is generally in reverse phase, and the gas-liquid contact process between the annular gaps in the internal structure of the equipment can be divided into two steps: the step is when the liquid phase is thrown away from the center and comes into contact with the gas in a cross flow manner; The second step is the process of the liquid phase falling onto a specific structural wall of the device. The gas in the annular gap rotates upward, while the liquid rotates downward under the influence of gas and gravity, resulting in counter current contact. In the second step, the liquid rotates along the wall and collides and squeezes with the constantly ejected liquid, resulting in a very fast surface renewal and a * mass transfer rate. This is similar to a wet wall tower that undergoes a series of extremely fast liquid surface renewals. The gas-liquid inside the equipment passes through an annular gap like passing through a wet wall tower, with higher mass and heat transfer efficiency.

Advantages of rotary distillation technology:
(1) Compared with distillation towers under the same conditions, steam energy consumption is reduced by 25%.
(2) Very high liquid velocity, suitable for processing high viscosity materials;
(3) The degree of micro mixing is high, suitable for processes such as gas lift and blow off;
(4) Very small liquid holding capacity, suitable for handling valuable/toxic materials;
(5) The gas-liquid residence time is extremely short (10-100s), suitable for the separation of thermosensitive systems;
(6) The rotor is self-cleaning and suitable for handling materials containing solid/scaling;
(7) The installation direction is arbitrary, resistant to bumps, and can be installed on moving objects.
(8) The mass transfer efficiency is very high and it is not easy to overflow.

The rotary distillation machine generally only takes about 10 minutes to operate normally. Users can perform intermittent or continuous operations according to the actual situation. In addition to conventional organic solvents, it also has advantages in handling valuable materials, thermosensitive materials, high viscosity materials, or toxic materials. At the same time, maintenance is convenient and does not require filling. Moreover, the replacement of traditional tower equipment with (supergravity) distillation technology equipment can save steel resources for the development of society; For the development of enterprises, it can save resources, reduce energy consumption and emissions, and improve product quality. This technology has broad application prospects in industries such as environmental protection, pharmaceuticals, supergravity desulfurization, chemical engineering, pesticides, biochemistry, materials chemistry, dyes, and pharmaceuticals, and is increasingly being chosen by more and more users.
