Problems solved by technology
[0007] The present invention aims to provide a 3D printing method of gas-compensated fan-shaped structured packing for a high-gravity rotary bed, aiming at the uneven distribution of packing, poor dynamic balance, easy blockage, difficult maintenance and replacement, and poor structure of the existing high-gravity rotary bed. For delicate problems, the new 3D structured packing designed by this method has the advantages of high mass transfer rate, small gas phase pressure drop, good dynamic balance performance, large flux, and convenient installation and maintenance.

Embodiment 1
[0041] Such as Figure 1~7 As shown, the model is constructed using three-dimensional modeling software. The model is composed of two parts: a fan-shaped structure and a wire mesh structure distributed in a ring. The fan-shaped structure and the wire mesh structure are nested with each other and support each other to form the main body of the filler; and then manufactured by 3D printing technology. Out of fan-shaped structured packing. The filler main body has a stable structure and at the same time plays the roles of large-scale fluid shear dispersion and small-scale fluid capture and dispersion.
[0042] The screen structure is a cylindrical structure composed of regular triangles, and multiple screen structures are superimposed in the radial direction to form a disturbance screen structure, which is a part of the main body of the filler.
[0043] The basic unit of the fan-shaped structure is a structure formed by fan blades arranged in sequence along the ring, the fan-shap...

The invention discloses a 3D printing method of gas compensation fan-shaped regular fillers for a supergravity rotating bed. The method comprises the following specific steps: three-dimensional modeling software is used for building a model, wherein the model mainly consists of fan blade structures and a silk screen structure with axial symmetry, so that the dynamic balance of the whole structureof fillers is guaranteed; a certain gap is formed between two adjacent layers of the fan blade structures to realize multiple times of acceleration and deceleration of gas in the fillers so as to prevent blockage of the fillers; the silk screen structure consists of regular triangles to achieve the effects of large-scale liquid shearing dispersion and small-scale fluid collection; and after the model is built, a 3D printing technology is used for manufacturing a solid model. In the regular fillers, when the fan-shaped structures guarantee the gas stop time, the fillers achieve a gas flow guideeffect, so that a fan can be saved; and due to the characteristics of the silk screen structure and special building mode thereof, the gas-liquid mixing is more sufficient, the mass transfer effect is further improved, and the equipment separation and microscopic mixing capacity is greatly improved.
Description
technical field [0001] The invention relates to a 3D printing method of a gas-compensated fan-shaped structured packing for a high-gravity rotating bed, and belongs to the technical field of mass transfer reactions. 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, and it is concentrated in the aspects of high-...
