3D printing method for structured packing for supergravity rotation bed with constant channels

Abstract

The invention discloses a 3D printing method for structured packing for a supergravity rotation bed with constant channels. According to the specific method, firstly, three-dimensional modeling software is utilized for constructing a circumferential silk screen structure with center symmetry, and an integral packing silk screen structure is constructed at equal intervals in the radial direction; supporting units with center symmetry are formed by using three interference structures in the radial direction, all the units are staggered by a certain angle to be sequentially arranged in the axialdirection, and accordingly an integral supporting structure is formed; finally, the supporting structure and the silk screen structure are assembled together, and a three-dimensional model for the structured packing for the supergravity rotation bed with center symmetry and the constant liquid and gas channels is formed; and finally, the 3D printing technology is utilized for manufacturing a solidmodel. According to the provided packing, gas and liquid mixing is very sufficient, the packing mass transfer effect is enhanced, and the equipment separation capability is improved; and the packinghas axial symmetry, dynamic balance is guaranteed, and the constant channels are achieved for the liquid phase and the gas phase.
