Abstract

Abstract

In this paper, aiming at the problem of the decrease of periodic water production volume of the spherical high-speed mixed bed in the power plants, a three-dimensional model of a typical spherical high-speed mixed bed water distribution device was established, and the dome, wave baffle and self-developed spiral diversion were studied using CFD and fluid-solid coupling methods. The performance and difference of the water distribution device in terms of the distribution of condensed water, the flow characteristics, and the changes in the mechanical properties of the structure under the action of the flow load were determined. The speed standard deviation was used as the fluid flow uniformity index, and the maximum deformation of the porous plate was used as the anti-deformation index. The calculation results showed that, at a flow rate of 200~700 t/h, compared with the dome-shaped baffle and corrugated plate structure, the water distribution uniformity of the self-developed spiral deflector water distribution device was increased by 47.3%~59.3%. And then the maximum deformation decreased by 12.2%~27.2%, and the water distribution effect was improved significantly.
