Corrugated packing grid and structured packing assembled from several packing grids

摘要

A corrugated packing grid with consecutively arranged wave crests and wave troughs for a structured packing, which is assembled from several packing grids, for gas-liquid contacting apparatuses, and a packing assembled from the packing grids. The packing grid and the packing have a large mass transfer area and a low pressure drop at the same time and offer a high mechanical strength. This can be achieved in that elements lie in the region of the wave troughs of the packing grid, the elements extending into the wave troughs.

主权项

1. A corrugated packing grid for a structured packing assembled from a plurality of packing grids for gas-liquid contacting apparatus, the corrugated packing grid comprising:
a plurality of wave-like bands arranged in parallel, each wave-like band having wave crests and wave troughs, and spaced apart from adjacent wave-like bands, wherein all of the wave crests and wave troughs of the plurality of wave-like bands are in-phase and form grooves in the packing grid extending in a packing grid plane; and cross struts extending transversely to the bands and forming with the bands an open structure perpendicular to the packing grid plane.
