Background

The rectifying tower is a tower-type gas-liquid contact device for rectifying. 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 rectifying tower is also a mass and heat transfer device which is widely applied in petrochemical production.

The tray assembly is one of the important assemblies in the rectifying tower. When the existing tower plate component is used, if liquid-phase substances flow into the tower plate too much, the liquid-phase substances are difficult to rapidly pass through the sieve holes on the tower plate, so that part of the liquid-phase substances are retained on the tower plate for a long time, and the rectification process can be seriously influenced by the phenomenon.
