Problems solved by technology

One of the inventors of this patent once applied for Chinese patent 200520005452.5, which proposed a stepped saddle ring particle packing, which has a 10-20% improvement in processing capacity compared with the traditional saddle ring, but the mass transfer efficiency is improved. Not significant, there is still room for improvement and improvement in terms of handling capacity and mass transfer efficiency

Embodiment 1

[0039] Embodiment one: the diameter is The filler has a height of 35mm, a width of 24mm, an aspect ratio of 0.68, a maximum length of the tongue piece of 10mm, and two curved wavy arc pieces inside the filler.

[0040] The filler is suitable for separation towers with small diameters (such as less than φ1500mm).

[0041] Using this filler, the kerosene-water system was used to carry out the extraction hydraulics test, and the gas-liquid two-phase flow rate comparison at the time of flooding is as follows: image 3 As shown, the flooding flux of this packing is significantly higher than that of Pall Ring and IMTP packings. Under the same liquid flux, the gas flooding velocity increases by 15% to 35%. Ring and IMTP decreased by 13% to 40%, and the mass transfer performance was also greatly improved, such as Figure 4 shown. In addition, the pressure drop of multi-ring packing is also lower than that of Pall Ring and IMTP, such as Figure 5 shown.

Embodiment 2

[0042] Embodiment two: the diameter is The packing height is 46mm, the width is 26mm, the aspect ratio is 0.56, and the maximum length of the tongue is 15mm.

[0043] The packing is suitable for medium-sized separation towers (such as φ1500-2500mm).

Embodiment 3

[0044] Embodiment three: the diameter is The packing height is 70mm, the width is 30mm, the height-to-diameter ratio is 0.43, and the maximum length of the tongue is 20mm.

[0045] The filler is suitable for separation towers with large diameters (such as greater than φ2500mm).

Abstract

The invention relates to a high-efficiency random filler, and in particular relates to a multi-ring filler which is formed by stamping and bending a rectangular thin metal sheet; four inward-bending or outward-bending circular arcs are formed along the direction of the length of the metal sheet, two inward-bending or outward-bending circular arcs are respectively formed on two sides of the direction of the length of the metal sheet, and two circular arcs on the same side are opposite in direction. Each circular arc is provided with a rectangular window, window leaves are bent inward to form tongue pieces, and the middle of the metal sheet is bent inward or outward to form two or more curved wave arcs which are opposite to each other in the direction. Both ends of the metal sheet are provided with zigzag shapes, and the metal sheet is provided with fine lines, and according to the width of the circular arcs and the wave arcs, five or more slits are sequentially cut in the middle of themetal sheet. The filler has simple manufacture, large processing capacity, high mass transfer efficiency, low pressure reduction and high mechanical strength, and is especially suitable for vapor-liquid and liquid-liquid mass transfer separation processes in the fields of chemical industry, petrochemical industry and environmental protection.

Description

technical field [0001] The invention relates to a packing in a chemical separation packing tower, which is a high-efficiency random packing made of sheet metal stamping, and belongs to the technical field of chemical separation and mass transfer equipment. Background technique [0002] Packed tower is a mass transfer and reaction equipment with vapor-liquid or liquid-liquid two-phase contact. It is widely used in chemical separation process in chemical industry, light industry, environmental protection and other fields. The packing performance directly affects the processing capacity and mass transfer efficiency of the packed tower. . The saddle ring random packing is a kind of random packing researched and developed by Norton Corporation of the United States. It is the most widely used random packing at present, but it is reflected in the actual application that the packing has the advantages of processing capacity, mass transfer efficiency, pressure drop, etc. There is ro...
