The distillation tower is a tower steam-liquid contact device for distillation. The distillation uses the components of the mixture with different volatilization, that is, the vapor pressure of each component at the same temperature, so that the light component in the liquid phase (low boiling) is transferred to the gas phase, and the recombination in the gas phase (high boiling) is transferred to the liquid phase, so as to achieve the purpose of separation
