Embodiment Construction

[0017] The implementation of the present invention will be described below in conjunction with the accompanying drawings, but they do not constitute a limitation of the present invention, and are only examples. At the same time, the advantages of the present invention will become clearer and easier to understand.

[0018] refer to Figure 1-4 As shown: vertical hole multifaceted corrugated packing of the present invention, the vertical hole mesh plate 1 is composed of a bottom plate 1.1 and a channel 1.2, and the described channel 1.2 is evenly spaced up and down with the bottom plate 1.1 as the axis; the vertical hole mesh plate 1 has a plate thickness of 0.1 -0.5 mm, the height is 10-500 mm, the opening rate of the upper and lower areas is 35%-95%, the height of the upper area is 1-9 mm, the height of the lower area is 1-9 mm, and the opening rate of the central main area is 70%-95%; the corrugated sheet 2 processed by the vertical hole screen 1 has a peak height of 1-9 mm,...

Abstract

The invention discloses vertical hole polyhedral corrugated packing and structured packing. A vertical hole screen (1) is composed of a bottom plate (1.1) and channels (1.2), wherein the channels (1.2) are uniformly formed at intervals from top to bottom by taking the bottom plate (1.1) as an axis; the thickness of the vertical hole screen (1) is 0.1-0.5mm, the height of the screen is 10-500mm, the aperture ratio of the upper and lower end area is 35-95 percent, the height of the upper end area is 1-9mm, the height of the lower end area is 1-9mm, and the aperture ratio of a middle main area is 70-95 percent; and according to a corrugated plate (2) processed by the vertical hole screen (1), the crest height is 1-9mm, the included angle between two corrugations is 30-60 degrees, and the distance between the two corrugations is 7-40mm. The defects such as short liquid retention time and low aperture ratio in the prior art are overcome, and the packing has the advantage of reducing liquid resistance.

Description

technical field [0001] The invention relates to the technical field of packing, in particular to a vertical hole multifaceted corrugated packing, and also relates to a structured packing composed of the vertical hole multifaceted corrugated packing. Background technique [0002] Since the structured packing was proposed in the 1970s, after more than 30 years of development, it has been widely used in petrochemical, chemical fertilizer industry, natural gas purification, air separation and other fields. At present, the typical structured packing is corrugated metal plate structured packing. When this packing is used for gas-liquid mass transfer operations such as rectification or absorption, the gas-liquid two phases in the packing are generally in countercurrent contact mass transfer or heat transfer, and the liquid phase is along the The surface of the filler flows downward in a film shape. When the liquid film is flowing, one side is the gas-liquid contact surface, and the...
