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.
