撞击流吸收器中铁系脱硫剂运动特性的CFD研究
The CFD study of ferrite desulfurization movement characteristics in impinging-streams desulphurization absorber
摘要
Abstract
A 3-D numerical simulation of movement characteristics of iron particles in Impin-ging-Streams (IS) desulphurization absorber was made with software FLUENT.Renor- malization Group Model(RNG k-e model)and Discrete Phase Model (DPM) was adopted for calculation of continuous phase and discrete phase, respectively. Calculation results show that the iron particles forced by inert and friction penetrate to and from in the impingement zone between accelerate tubes, and the movement {ield o{ iron particles is also symmetrical to the impingement plane like air flow, that meets well with IS theory. Iron particles' aver- age residence time increases with increment of air inlet velocity and decreases with incre- ment of particle diameter and accelerate tube distance, the trend are basically in agreement with available experimental data. As a result, the study provides valuable basic data and theoretical bases.关键词
