Embodiment Construction

[0033] The present invention is further illustrated by the following examples, but not limited to the following examples.

[0034] Figure 1 to Figure 6 It is the specific process of using 3D software to construct the packing model.

[0035] Such as Figure 1 to Figure 6 As shown, the packing model is constructed using 3D software. The basic unit 1 is arrayed in a ring to form a ring unit 2. The ring units 2 are staggered and nested from inside to outside to form a disc-shaped body 4 under the premise of ensuring dynamic balance. The disc-shaped body 4 In the radial direction, each layer is staggered and superimposed by 0~10° to form a packing body 5 with a regular perturbation structure in the axial direction and an interlaced axial wire mesh. Finally, the packing entity 6 is printed by 3D printing technology.

[0036] The invention provides a method for 3D printing structured packing for a high-gravity rotating bed, using three-dimensional modeling software to build a mode...

Abstract

The invention discloses a packing structuring method for a 3D printing supergravity rotating bed. The method comprises the specific steps that three-dimensional modeling software is utilized for constructing a model, the model is formed by stacking units composed of lead screw structures according to a certain regular, and therefore a grid structure with a regular disturbing structure in the axialdirection and with a dense staggered structure in the radial direction is formed; and finally a solid model is manufactured through the 3D printing technology. A special setup manner is adopted by novel packing, through combination with the advantages of the grid structure, a reasonably-distributed gas-liquid channel is constructed, high porosity is guaranteed, blocking is reduced, and meanwhilefluid can collide with the packing repeatedly in the process of penetrating through the pacing, the direction is changed constantly, the packing is dispersed and gathered, and the motion form is closeto irregular motion; pressure drop is reduced, meanwhile, the time of retention reacting and the flowing direction in the packing are obviously prolonged, gas and liquid are mixed more sufficiently,and the mass transfer effect of the packing is strengthened; and the operation stability of a supergravity device is increased by the structured packing.

Description

technical field [0001] The invention relates to a method for 3D printing a structured packing for a high-gravity rotating bed, and belongs to the field of mass transfer reaction equipment. Background technique [0002] Supergravity technology is a new technology to strengthen multiphase flow transmission and reaction process. Since the advent of the supergravity machine in the last century, it has been widely valued at home and abroad. Because of its wide applicability and its small size, The advantages of light weight, low energy consumption, easy operation, easy maintenance, safety, reliability, flexibility, and better adaptability to the environment make supergravity technology have broad commercial application prospects in environmental protection, material biochemical and other industrial fields. However, the current high-gravity technology is still mainly in the application and development stage, which is concentrated in two aspects: the super-gravity gas-solid fluidiz...
