摘　　要：针对新疆沙漠油田地下水水质差,现场作业人员饮水困难问题,研制了一套沙漠油田板式蒸馏淡化装置。该装置采用8效蒸发器加1效冷凝器结构,热源为槽式太阳能集热器或燃气发电机组配套余热锅炉提供的热水,额定产水量为1 m^3/h。通过理论分析,建立了传热传质数学模型,并对预处理系统、进料水系统、产品水系统、浓盐水系统、抽真空系统、加热水系统和清洗系统的设计,以及装置关键部件的研发做了分析说明。该装置在现场通过了全流程稳定性测试,应用结果表明,能够满足新疆沙漠油田现场作业人员饮用水要求,具有较好的推广应用前景。According to the problems of the poor water quality in Xinjiang desert oil field and the lack of drinking water for the field staff, a set of multi-effect plate distillation device for underground brackish water desalination is developed. The device consists of eight-effect evaporators and one-effect condenser. The heating source is hot water provided by trough solar collectors or waste heat boiler of gas generator. The device produces freshwater at a rated output of 1 m^3/h. The relative mathematical model about heat and mass transfer is established on the basis of the theoretical analysis. All the items including the pretreatment unit, feed water unit, product water unit, brine system, vacuum unit, heating unit, cleaning unit and the key components of the device are analyzed and explained in detail. The test of operation stability indicates that the device can meet the drinking water requirements for the staff in Xinjiang desert oil field. So it has good promotion and application prospect.
