Overview
       Distillation tower is chemical equipment made of rare metal titanium and other materials and its alloy materials.
       It has the characteristics of high strength, great toughness, high temperature resistance, corrosion resistance and light specific gravity.
       Therefore, it is widely used in chemical industry, petrochemical industry, metallurgy, light industry, textile, alkali production, pharmaceuticals, pesticides, electroplating, electronics and other fields.

Classification
       The distillation tower is a tower-type gas-liquid contact device for distillation.
       There are two main types: plate tower and packed tower.
       The comparison between plate towers and packed towers is a complex issue involving many factors. When selecting, the material properties, operating conditions, performance of the tower equipment, and the manufacturing, installation, operation and maintenance of the tower equipment should be considered.

Working principle
       The principle of distillation in a distillation tower is to partially vaporize a liquid mixture, and use the characteristics of different volatilities of each group to achieve separation. The column kettle is liquid, and the gas is distilled from the top of the column.
       The main function is to separate mixed liquids, using the principle of different liquids under different conditions, such as different temperatures and different volatilities (boiling points), to achieve purification effects.
