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 figure 2 As shown (the dotted line in the figure shows the U-shaped upper bottom of the crest and trough when the filler is actually manufactured), the height of the crest is h, the width of the upper bottom of the trapezoidal crest (or trough) is a, and the peak (or trough) The width of the lower bottom of ) is a+2b, the angle between the ex...

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 consists of a series of corrugated sheets placed vertically and parallel to each other. The structural parameters of the corrugated sheets are as follows: figure 1 As shown in the figure, there are jagged peaks and troughs on each corrugated sheet in the figure, the corrugated addendum angle θ is 90°, the height of the crest is h, the wave distance is 2b, and the inclined side of the crest (or trough) is s. ...
