Embodiment Construction

[0018] The trapezoidal corrugated structured packing proposed by the present invention is described in detail as follows in conjunction with the accompanying drawings and examples:

[0019] The trapezoidal corrugated structured packing of the present invention is composed of a plurality of corrugated sheets, each corrugated sheet has crests and troughs, each corrugated sheet is placed parallel to each other vertically, the corrugated direction has an inclination angle with the vertical direction, and the corrugated inclination angle of adjacent corrugated sheets is Equal and opposite in direction; the shape of each corrugated sheet is as shown in Figure 2 (the dotted line in the figure shows that the crest and trough are U-shaped upper bottom when the packing is actually manufactured), the height of the crest is h, and the trapezoidal crest ( The width of the upper bottom of the crest (or trough) is a, the width of the lower bottom of the crest (or trough) is a+2b, the angle be...

Abstract

A trapezoidally corrugated filler for increasing the gas-liquid contacting area and mass transfer efficiency is composed of multiple trapezoidally corrugated sheets.

Description

technical field [0001] The invention belongs to the technical field of packing in the field of chemical separation engineering, in particular to the structural improvement of corrugated structured packing. Background technique [0002] Due to the symmetry of its geometric structure, the corrugated structured packing provides a uniform and regular gas-liquid flow path, reduces wall flow and channel flow, and presents good performance of low pressure drop, large flux and high efficiency. It has been widely used in chemical and environmental fields. The corrugated packing is composed of a series of corrugated sheets placed vertically and parallel to each other. The structural parameters of the corrugated sheets are shown in Figure 1. In the figure, each corrugated sheet has a jagged crest and trough, and the angle θ of the corrugated tooth tip is 90°. The height of is h, the wave distance is 2b, and the slope of the crest (or trough) is s. The corrugation direction has an inc...
