石灰浆液荷电喷雾脱硫流场的数值模拟
Numerical simulation of flow field on desulphurization through electrostatic spraying of lime slurry
摘要
Abstract
In order to investigate the mechanism of lime slurry droplet charging and absorbing SO2 , the e-lectrostatic spraying two-phase flow field of lime slurry was numerically simulated. Geometric model, electrostatic model and two-phase flow model were established based on the characteristics of desulphurization tower and charge electron spray desulphurization. The characteristic of ring-like electrostatic field was obtained by extending commercial Fluent 6. 3 function to achieve the coupled simulation between electrostatic field and two-phase flow field. The two phase flow characteristics and desulphurization effect under the condition of slurry electric charge were analyzed. The results show that the distribution of electric intensity is basically symmetrical about the desulfurization tower axis. The electric intensity decreases rapidly with the increasing of distance away from electrode. The outboard entrainment zone is increased and the velocity is decreased by electron charge in slurry drop, and the zone near electrode effected by jet flow is shortened to strengthen the two phase contact and SO2 absorption. The electrostatic charged desulphurization with same flows direction is better than that with opposite flow direction.关键词
