摘　　要：电化学除碳酸钙垢过程中,大量的沉积物覆盖在阴极表面,导致除垢效率降低,应及时对阴极表面进行脱垢处理。本文首先搭建了超声波清洗装置,研究了超声波频率、功率、时间对带垢极板脱垢效果的影响规律。其次,将阴阳极反接,实验研究了不同电流密度、时间下带垢极板的脱垢效果。最后从除垢率和除垢时间综合对比分析了阴阳极反接和超声波除垢的效果,提出了电化学除碳酸钙垢阴极表面脱垢工艺技术,为电化学沉积法去除油田采出液碳酸钙垢的技术推广提供支持。In the process of electrochemical calcium carbonate scaling removal,a large amount of sediment covers the surface of the cathode,resulting in reduced scaling efficiency,and the cathode surface should be treated in time.Firstly,an ultrasonic cleaning device was built,and the influence of ultrasonic frequency,power and time on the descaling effect of the plate was studied.Secondly,the descaling effect of the scale plate with different current density and time was studied experimentally by inversely connecting the anode and cathode.Finally,the effect of anode and cathode reverse connection and ultrasonic descaling is compared from the rate and time of descaling,and the cathode surface descaling technology of electrochemical descaling is proposed,which provides support for the technology promotion of removing calcium carbonate scale from oilfield produced liquid by electrochemical deposition.
