Abstract

Adopting the numerical simulation technology

through varying parameters

such as flue gas flow velocity

blade spacing

number of allocated stages

and diameter of fluid-drop etc.

numerical simulation and calculation of multi-phase flow field in the folded plate type demistor have been carried out

the influence of each parameter upon the dewater efficiency being analysed

and a feasible scheme for enhancing the dewater efficiency being put-forward.The result of simulation basically tallies with practical operation situation in the field

proving the numerical simulation technology can be used for optimized design of the demistor for wet desulfuration.
