Gravity Distillation equipment manufacturers packing tower structure principle
Packed tower is tower packings as the gas-liquid contact member between the two phases of mass transfer equipment. The tower is packed column has a vertical cylinder (as shown above), at the bottom with packing support plate, filler huddle or the whole puzzle set in a support plate. Install the packing above the filler plate to avoid being blown updraft. Liquid from the top through the liquid distributor sprayed onto the filler, and flow along the surface of the filler. Gas is fed from the bottom, through the gas distribution system (small diameter column generally no gas distribution device) after the distribution, and continuous countercurrent liquid through the gap filler layer was on the filler surface, in close contact with the two-phase gas-liquid mass transfer . Packed tower belonging continuous contact liquid mass transfer equipment, two phases along the tower height changes continuously under normal operating conditions, the gas phase is a continuous phase, liquid phase to the dispersed phase.
When the liquid flows downward along the filler layer, there is a gradual trend towards centralized tower wall, making the fluid flow near the wall of the tower increases, a phenomenon known as wall flow. Wall liquid two-phase flow effects caused by the uneven distribution of the filler layer, so that the mass transfer efficiency. Thus, when a high packing layer, the need for segmentation, intermediate redistribution device settings. Liquid redistribution device comprises a liquid collector and liquid redistribution of two parts, a top packing shed liquid after the liquid collector to collect, to liquid redistributors, after redistribution sprayed onto the lower filler.
Packed tower having large capacity, high separation efficiency, pressure drop, holding a small amount of liquid, operating flexibility and other advantages.
Packed column, there are some shortcomings, such as packing high cost; when the liquid load is small can not be effectively wetting of the filler surface, so that the mass transfer efficiency is reduced; it can not be directly used for suspended solids or easily polymeric materials; contralateral line feed and the material is not suitable for complex distillation and the like.
