| 摘 要： | 在污垢热阻动态监测装置上,进行了高压静电抗垢强化传热实验研究．结果表明,成垢溶液经过高压静电处理以后在换热表面结垢减轻,污垢热阻明显减小,阻垢率可达到56．5％．对污垢晶体的扫描电镜观察表明,高压静电处理后污垢晶体形态发生了改变,由结构致密型的霰石改变为结构松散的不定形体,从而不易在换热表面结垢。

| Abstract: | The anti-fouling experiments using high voltage electrostatic field for heat transfer enhancement were carried out with the dynamic fouling test facility. The results indicated that, for the case of treatment with high voltage electrostatic field, the deposits on the heat transfer surface mitigated, and the fouling thermal resistance decreased extraordinarily with a scale inhibition rate of 56.5%. SEM showed that the crystal shape of the CaCO3 changed from a compact aragonite structure for no treatment case to a incompact indefinite structure for treatment case. And thus, it was difficult for the scale to form on the heat transfer surface. |
