摘　　要：介绍了一种载金炭高效常压溶剂蒸汽解吸-电解新装置及其控制系统。该装置率先将解吸与电解采用各自的专用设备,断开分成为两个工序进行,消除了安全隐患,并实现了安全、高效生产。其控制系统采用5路温度检测、2路PID温度调节与1路液位控制组成了对溶剂蒸汽解吸与贵液电解的有效控制,具有简捷、可靠、方便、实用的特色。推广应用表明,采用本工艺技术,所需解吸时间仅为10～11 h、解吸率高达97%～99%、所需解吸液体积<1 m3/t炭、解吸后贵液的含金浓度为5 000～8 000 g/m3、电解回收率>99%、解吸-电解总回收率达到97%～98%,而且能耗低、无污染,具有良好的经济效益与社会效益。A new kind of gold loaded carbon＇ s high efficient atmospheric pressure solvent desorption with steam-electrolysis device and its control system is introduced in this paper. This device take the lead in disconnecting desorption and electrolysis into two working procedures with each one＇ s special equipment, thereby hidden danger is eliminated and the safe, high efficiency production is realized. Its control system is composed by 5 way temperature detection, 2 way PID temperature regulation and 1 way liquid level control, which can effectively control the solvent steam desorption and pregnant solution electrolysis, which has the simple, stable, convenient and practical feaures. Popularization and application shows, if this process technology is adopted, the needed desorption time is only 10 -11 hours, and the desorption rate reaches up to 97 % -99%, the needed desorption solution volume 〈 1 m^3 per ton of carbon, the gold bearing concentration of pregnant solution after desorption is 5 000- 8 000 g/m^3 ; the electrolysis recovery rate 〉 99%, the total recovery rate of desorptionelectrolysis is 97%-98% ; it has low energy consumption and has no pollution, it has the good economic benefits and social benefit.
