Distillation tower manufacturer: The principle of rectification is to partially vaporize and partially condense the liquid mixture many times, and use the characteristics of different volatility of each component to achieve a unit operation for the purpose of separation.
The vapor inlet of the rectification tower is usually placed at the bottom of the tower. The vapor phase evaporated from the tower is in countercurrent contact with the descending liquid. During the two-phase contact, the volatile (low boiling point) components in the descending liquid continuously transfer to the gas phase. The hard-to-volatile (high boiling point) components in the liquid are continuously transferred to the descending liquid. The closer the gas phase is to the top of the tower, the higher the concentration of its volatile components, and the closer the descending liquid is to the bottom of the tower, the more concentrated its hard-to-volatile components. , So as to achieve the purpose of component separation.
The gas phase rising from the top of the tower enters the condenser at the top of the rectification tower, part of the condensed liquid returns to the top of the tower as reflux and enters the rectification tower, and the rest is taken out as distillate.
Part of the liquid flowing out of the bottom of the rectification tower enters the reboiler, is heated and evaporated into a gas phase and returns to the rectification tower, and the other part of the liquid is discharged as the bottom of the kettle.
