The principle and characteristics of high-efficiency rotary distillation machine
Date: 2024-10-28Read: 5
Efficient rotary distillation machines are widely used in ethanol, methanol, acetone, ethyl acetate, acetonitrile, tetrahydrofuran, dichloromethane DMF、DMSO、 The recovery and product separation and purification of organic solvents such as toluene, isopropanol, and tert butanol have been widely applied in industries such as raw materials, pharmaceutical intermediates, fine chemicals, biodiesel, environmental protection, and liquor production. The materials used for the contact parts between equipment and materials are 304, 316L, spray coating, titanium, etc. according to the user's needs.
The principle of efficient rotary distillation machine:
(1) By using centrifugal force to disperse the liquid and then bringing it into contact with the gas, it is more thorough than directly contacting the liquid with other substances, improving the specific surface area and mass and heat transfer rate and efficiency of gas-liquid phase contact, and greatly reducing the size of the equipment.
(2) A rotor with a specific structure rotates at high speed inside the body. The gas phase enters the machine through the gas inlet and enters the rotor from the outer edge, while the liquid phase enters the center of the rotor through the inlet. The gas-liquid phase forms a gas-liquid interface with a large specific surface area and constantly updates inside the rotor, which has a high mass and heat transfer rate and efficiency. The final gas phase leaves the bed through the outlet and is condensed by the condenser; The liquid phase is collected inside the machine and discharged from the outlet.
The high-efficiency rotary distillation machine has the following advantages:
⑴ High efficiency, low energy consumption (saving 10% to 50%);
⑵ High mass transfer rate and short gas-liquid residence time;
⑶ Small liquid holding capacity and strong anti blocking ability;
⑷ Small footprint, convenient for indoor use, safe and reliable;
⑸ Easy to operate, easy to clean, with a large processing capacity;
⑹ Low cost.
