Numerical Simulation of Particles Deposition in Hollow Fibre Membrane Tube

The deposition performance of the particles in hollow fiber membrane tube were simulated by calculating fluid dynamic (CFD) with the particles diameter 0.05 mu m similar to 2 mu m. The flue gas and particles were simulated by using Laminar Model and Discrete Phase Model respectively. The result shows that the deposition rate is low in membrane tube, the drag force is the control factor of particle flowing in thin tube. When the membrane tube with small diameter is short and vertical, the deposition rate can decrease, the gravity has no effect on the deposition rate when membrane tube is vertical; Temperature has no effect on it at rang of 15 degrees C similar to 60 degrees C. The conclusions give reference to choice membrane and operation mode in flue gas desulfurization process with hollow fiber membrane.
