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 equipment used in the rectification process is called rectification tower, and can be divided into ① plate type towers, the gas phase and liquid phase are in countercurrent contact for many times, the gas phase and liquid phase on each layer of the tower are in cross flow, ② packed tower, the gas phase and liquid phase are in continuous countercurrent contact.
The tower body of the packed tower is a vertical cylinder, and the bottom of the packed tower is provided with a supporting plate. The packing is placed on the support plate in a random or monolithic manner. A packing press plate is installed above the packing to restrict the movement of the packing with the updraft. The liquid phase is added from the top of the tower, sprayed onto the filler through a liquid phase distributor and flows down along the surface of the filler. The gas is fed from the bottom of the tower, distributed by a gas distribution device (the small-diameter tower is not provided with the gas distribution device generally), and continuously passes through the gaps of the packing layer in a counter-current manner with the liquid phase. The gas phase and the liquid phase are closely contacted on the surface of the filler for mass transfer. The packed tower belongs to continuous contact type gas-liquid mass transfer equipment, the composition of two phases continuously changes along the height of the tower, and under the normal operation state, a gas phase is a continuous phase, and a liquid phase is a dispersed phase.
When the packing layer is higher, the liquid phase flows downwards along the packing layer, and tends to be gradually concentrated towards the tower wall, so that the liquid flow near the tower wall is gradually increased, the phenomenon is called wall flow, and the wall flow effect causes the gas phase and the liquid phase to be unevenly distributed in the packing layer, so that the mass transfer efficiency is reduced. Improvements are therefore needed.
