磁场和促垢剂对CaCO3垢成核诱导期的协同机理
Synergistic mechanism of magnetic field and scale promoter on the nucleation induction period of CaCO3 scale
摘要
Abstract
The fouling accumulation and removal device has the advantages of fixed-point fouling and descaling and alleviating the fouling problem of subsequent process pipelines.However,due to the fact that the residence time of the fluid in the device is too short,the overall descaling efficiency is relatively low.In order to shorten the fouling time and increase the growth rate of CaCO3 crystallization fouling,the influence mechanism of magnetic field intensity,the type and concentration of scale promoters and their synergistic effect on the nucleation induction period of CaCO3 scale was explored through an experimental system.The results showed that the scale promoter can significantly increase the heterogeneous nucleation speed of calcium carbonate scale.The action of the magnetic field enhanced the collision probability of the scale-forming particles and effectively promoted the formation of crystal nuclei.Their synergy not only promoted the transformation of calcite-type calcium carbonate to aragonite-type calcium carbonate,making the surface of the scale layer uneven,but also reduced the electrostatic repulsion between particles.Compared with the control group,the nucleation induction period after the synergistic effect of the two was shortened by 13min.关键词
