Structured packing for gas-liquid mass transfer unit

摘要

In existing structured packing, performance depends on effective contacting area. Performance decreases in cases having high surface tensions such mixtures containing a lot of water. Such mixtures are difficult to wet the packing surface. The present invention prevents liquid from intersecting the crease of the corrugation and from falling into a free space. Further, liquid flowing into the slot makes frequent liquid and vapor interfacial update resulting in positive utilization of the wetted area. The most important point of this invention is taking a positive utilization of the wetted area. The most important point of this invention is taking a large value of 3.5 or more of P/H (pitch/height of the crimp) and providing the horizontal slot on the crease, resulting in adding the flow reversal mechanism and frequent interfacial update.

主权项

1. A packing system comprising:
a plurality of sheets, each sheet of the plurality of sheets comprising a first bend and an opposite parallel second bend, the first bend and the opposite parallel second bend defining a waved surface; a plurality of slots, each slot of the plurality of slots disposed across at least one of the first bend and the opposite parallel second bend; a tab associated with each slot of the plurality of slots, the tab being joined to opposite edges of the slot and being deflected inwardly with respect to the first bend and the opposite parallel second bend; and wherein each sheet of the plurality of sheets is arranged in a cross-wise fashion relative to a vertically-adjacent sheet.
