Structured packing suitable for mosaic rotating packed bed and application thereof

Abstract

The invention discloses a structured packing suitable for a mosaic rotating packed bed and application thereof. The packingconsists of a structuredsilkscreen structure and a fin structure; the packingis in an annular shape and mainly consists of the structuredsilkscreen structure, and the fin structure is arranged on the outer side; according to the spatial configuration of the structuredsilkscreen structure, a plurality of layers of silk screens tangential to each other are arranged in the radical direction, each layer of the silk screen is a circle enclosed by a plurality of cubes, the diagonals of the faces and the diagonals of the bodies of the cubes are connected witheach other to form a triangle in a three-dimensional space, the utilization rate of the packing is increased bya regular gas-liquid passage, uniform dispersion of the gas and liquidis promoted, and resistanceis reduced; according to the fin structure,the silk screens or curved pieces formed by sheet-like bendingare assembled on the outer edge of the silk screen structure and are shaped like fan blades,and thebendingdirection of the fin structure is opposite to the rotating direction of a rotor. According to thestructured packing suitable for the mosaic rotating packed bed and the application thereof,a solid packing is constructed by 3D printing technology, the structured packingis composed of the structuredsilkscreen structure and the fin structure, and spoiling and dispersing ofthe gas and liquid are advantageous.

Description

technical field [0001] The invention relates to a structured packing suitable for a mosaic rotary packed bed and its application, belonging to the field of chemical mass transfer and reaction equipment. Background technique [0002] Hypergravity technology is a breakthrough technology developed in the 1980s to strengthen the multiphase transfer and reaction process. In a gravity environment, the liquid is sheared and atomized by the filler, the contact area between the phases increases, and the rapid renewal of the surface leads to a great enhancement of the mass transfer, heat transfer and reaction process controlled by the liquid phase, but there is little improvement in the mass transfer coefficient of the gas phase . [0003] Since the high-speed rotating packed rotor is the main place for the gas-liquid contact reaction, the main factor affecting the mass transfer coefficient of the gas phase is the packing structure of the rotating packed bed. Different packing struct...

Problems solved by technology

These kinds of fillers are all for the purpose of increasing the dispersion atomization and residence time of the liquid, thereby increasing the liquid phase mass transfer coefficient, but the strengthening effect on the gas phase mass transfer coefficient is not obvious.
