Ripple filling material with multiple layers of gas/liquid runners

Abstract

The invention discloses a ripple filling material with multiple layers of gas / liquid runners. The filling material is novel structured packing used in a packed tower. The filling material is composed of a plurality of filling blocks. Each filling block is prepared by laminating multiple ripple plate units. Each ripple plate unit is prepared by pressing a thin steel plate, a plate-flower net, a silk screen, and a non-metal belt together, and comprises two external ripple plates and one internal ripple plate. The internal ripple plate is arranged in the middle part of the ripple plate unit, and two external ripple plates are arranged on two sides of the middle part of the ripple plate unit. The gas / liquid runners of the external ripple plates and internal ripple plate are parallel to each other. The ripple filling material has the advantages of large flux, small resistance, high efficiency, and strong obstruction resistant performance, and can be used in the fields such as chemical engineering, oil refining, petrochemical industry, ethylene industry, pharmacy, natural gas industry, and the like.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a plate corrugated packing with multi-layer gas-liquid flow channels, which belongs to the innovation of the regular corrugated packing in the tower. Background technique [0002] Existing corrugated packing, such as Image 6 , Figure 7 , Figure 8 As shown, it is made on a thin steel strip (which can also be non-metallic) with several parallel corrugated flow channels with a triangular cross-section and a straight line at 30-45 degrees to the tower axis. The corrugated runners on the adjacent corrugated sheets are corrugated packing discs or blocks composed of several corrugated sheets arranged vertically to each other. This plate corrugated packing has been used for many years. The application of production practice has proved that it has the characteristics of high mass transfer efficiency, small pressure drop and wide operating flexibility. After reaching a c...

Problems solved by technology

This plate corrugated packing has been used for many years. The application of production practice has proved that it has the characteristics of high mass transfer efficiency, small pressure drop and wide operating flexibility. After reaching a certain value, continue to increase the specific surface area (such as 750m2 / m3 or more), which not only increases the resistance but also decreases the separation efficiency, and loses the original advantage of small pressure drop and high efficiency.
