Fin flow guiding regular packing for distillation operation of rotary packed bed

Abstract

The present invention relates to a filler for rotary filling bed, in particular to the pin-guided normal filling for the rectification of the rotary filling bed, which solves the poor gas-liquid reverse contact effect existing in the filling rectification of the rotary filling bed. The present invention comprises an upper disc and a lower disc; the upper disc is provided with a plurality of cylindrical upper guide plates with different diameters; the lower disc is provided with a plurality of cylindrical lower guide plates with different diameters; the upper guide plate and the lower guide plate are staggeredly arranged; a fluid channel is arranged between the upper guide plate and the lower disc and between the lower guide plate and the upper disc; the upper guide plate is provided with a plurality of downward-inclined fins and the lower guide plate is provided with a plurality of upward-inclined fins. The present invention expands the phase contact area, strengthens the turbulence degree of gas and liquid in filling, extends the flowing distance and contact time of the fluid in the filling, intensifies the mass transfer effect of the filling and further improves the separation ability of the equipment.

Description

technical field [0001] The invention relates to a filler for a rotary packed bed, in particular to a finned diversion structured packing for rectification operation of a rotary packed bed. Background technique [0002] The rectification process is actually a mass transfer and heat transfer process in which vapor and liquid are in countercurrent contact, and fillers play a vital role in this process. Scientific and technological workers have done a lot of work in the research and development of packing. Reasonable packing design can effectively increase the contact area of ​​vapor and liquid and prolong the contact time of vapor and liquid, so as to strengthen the microscopic contact and mixing effect of vapor and liquid. This improves the separation capability of the device. [0003] The rotating packed bed can greatly enhance the vapor-liquid contact effect in the rectification process. In addition to the supergravity effect formed under high-speed rotation, it is very im...
