In order to study the influence of installing double hook plates on performance of the plate demister and the removal rate of droplets with different particle sizes

the low Reynolds SST k-ω model was applied to numerically simulate the flow field inside the demister with double hook plates for the wet flue gas desulfurization system. The effects of the hook plates' structural parameters

gas flow rate and liquid droplet size on demisting efficiency and pressure drop of the demister were investigated. The results show that

compared with the demister with no hook

the one installing double hook plates has higher removal rate on droplets with smaller diameter. The removal rate of droplets with particle diameter of 10 μm increased from 7.99% to 23.14%

and that of the droplets with particle diameter of 20 μm increased from 31.63% to 60.49%. In addition

the removal rate of droplets with particle diameter larger than 30 μm reached up to 90%. The length of the hook piece is the main factor affecting the droplets' removal efficiency

while the width of the hook piece has a very small influence. Within the range of allowable pressure drop

the plate demister installed double hook plates enhances the removal rate of small liquid drops

which provides a theoretical basis for experimental research and design of mist eliminators.
