Study on the Gas Distribution Characters of the Outsize CO_2 Absorber of the Flue Gas in the Coal-fired Power Plant

摘要

In the article the flow field in the twin-tangential annular flow gas distributor was simulated based on the standard k-ε turbulent model with FLUENT software according to various distance L between sleeve and column wall and differing numbers of baffles, after comprehensively analyzing, got the best technological parameters with misdistribution factor and pressure drop. Based on the analysis of the flow field discipline of the twin-tangential annular flow gas distributor and the two-line vane gas distributor, and the systematic comparison of the performance of these two kinds of gas distributors in the flue gas CO_2 absorption column, the research will provide the important theoretical foundation for the choosing and designing of the distributor of the flue gas CO_2 absorber.
