Abstract

Abstract

In order to accurately obtain the gas-liquid two-phase reaction characteristics of the two-stage series tower desulfurization system, the gas-liquid two-phase flow and heat transfer process in the spray section of the double tower series wet desulfurization tower in a power plant were numerically simulated by using the step-by-step method and the self-developed tray model. A new system evaluation index was used to evaluate the desulfurization system, and the desulfurization system was optimized and evaluated by numerical simulation. The calculation results showed that no matter the pre washing tower or the absorption tower, the design of adding tray and efficiency ring reasonably could obtain better performance on the basis of opening less spray layer, which was conducive to reaching the higher standard of desulfurization, and reducing the amount of circulating slurry as well as reducing the pressure drop of the whole system of desulfurization tower and the power consumption.
