Overview
All kinds of towers are chemical equipment made of rare metal titanium and other materials and alloy materials.
It has the characteristics of high strength, high toughness, high temperature resistance, corrosion resistance and light specific gravity.
Therefore, it is widely used in the fields of chemical industry, petrochemical industry, metallurgy, light industry, textile, alkali making, pharmacy, pesticide, electroplating, electronics and so on.

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

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