Condensing structure of rectifying tower

Technical Field

The utility model mainly relates to the field of rectifying towers, in particular to a condensing structure of a rectifying tower.

Background

The rectifying tower is a tower type vapor-liquid contact device for rectification. By utilizing the property that each component in the mixture has different volatility, namely the vapor pressure of each component is different at the same temperature, the light component (low-boiling-point substance) in the liquid phase is transferred into the gas phase, and the heavy component (high-boiling-point substance) in the gas phase is transferred into the liquid phase, thereby realizing the purpose of separation. The general rectifying device consists of a rectifying tower body, a condenser, a reflux tank, a reboiler and other equipment. The boiling residue is condensed and extracted by a condensation structure.
