基于CFD的溶催同步臭氧反应器结构优化及流场分析
Structural optimization and flow field analysis of dissolved catalytic synchronous ozone reactor based on CFD
摘要
Abstract
Based on the Euler-Euler multiphase flow model and k-ε turbulence model,numerical simulations and structural optimizations were conducted to investigate the flow characteristics of the dissolved catalytic synchronous ozone reactor.Key parameters including the height-to-diameter ratio H/D of the reaction chamber,draft tube-to-reactor diameter ratio d/D,aperture ratio of the water-gas distribution plate and draft tube height were systematically analyzed.The results demonstrate that optimal flow field distribution and catalyst fluidization efficiency are achieved at H/D=2,d/D=0.65,and an aperture ratio of 0.44％.The optimized configuration establishs distinct upflow/downflow circulation zones,significantly enhancing catalyst-fluid flow interaction.The pressure-enhancing effect within the draft tube promotes ozone dissolution,with operational data showing a 51％increase in ozone dissolution concentration after jet-flow mixing and an 83％ enhancement following the reaction chamber treatment.This multi-stage dissolution system enables flexible process adjustment based on water quality requirements while maintaining robust operational stability.关键词
