Description
Technical Field
The invention relates to the field of chemical rectification processing, in particular to a plate-type rectifying tower.
Background
The rectifying tower is a tower-type gas-liquid contact device for rectifying. The light component in the liquid phase is transferred to the gas phase, and the heavy component in the gas phase is transferred to the liquid phase 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, so that the aim of separation is fulfilled. The rectifying tower is also a mass and heat transfer device which is widely applied in petrochemical production.
A plate-type rectifying tower is a widely used gas-liquid mass transfer equipment, which is composed of a generally cylindrical shell and a plurality of horizontally arranged plates at certain intervals in the shell.

The plate type rectifying tower is in the rectifying process, three problems occur most often, namely liquid foam entrainment, liquid leakage and flooding, the liquid foam entrainment refers to gas-liquid mixing, a large amount of liquid is entrained between tower plates, the liquid leakage refers to leakage of the liquid from sieve holes in the tower plates due to insufficient air quantity, the flooding refers to overlarge air quantity, the liquid phase on the tower plates on the lower layer is brought to the tower plates on the upper layer, and the traditional plate type rectifying tower can not effectively adjust according to the actual use condition although prevention and aiming are performed on the problems.
