Outline
Two kinds of double-hooked corrugated plate moisture separators with different draining hook structures were numerically investigated, and the gas-liquid two-phase flow model inside the corrugated plates was constructed by using computational fluid dynamics methods. The separation efficiency and pressure drop of the two corrugated plates were comparatively analyzed using the shear stress transport k-ω(SST k-ω) model and the discrete phase model(DPM) under different inlet velocity conditions. The results show that large-size droplets will be separated directly by impacting the separator wall under the effect of inertia, while small-size droplets with smaller inertia force and similar trajectory to the main stream will move with the main stream and are difficult to be captured. The draining hook structure will produce a certain amount of vortex, which will have a certain effect on the local gas flow rate of the flow field, and the main stream gas phase will bring in a portion of the droplets to increase its removal efficiency. When the inlet velocities of the SH-type and N-type corrugated plate are greater than 4 m/s and 6 m/s, respectively, the separation efficiency of the droplets with a particle size larger than 8 μm can reach 100%. When the overall separation efficiency of the two types of corrugated plates reaches 84%, the energy loss of the N-type corrugated plate is about twice as much as that of the SH-type corrugated plate. Comprehensive comparison of the pressure drop and separation efficiency of the two types of corrugated plate moisture separators with double hook, the similarities and differences in their structures, performance advantages and disadvantages were studied and analyzed.
