摘　　要：风力致热海水淡化是将风能直接转换成热能,再蒸发海水制取淡水的技术。文章论述了风力致热型海水淡化装置的结构和工作原理,介绍了S型垂直轴风力机、搅拌液体致热装置和海水蒸发室的特性。通过力矩的匹配计算,建立搅拌器直径的相关数学模型,并依据最优匹配数学模型计算搅拌液体致热装置的参数。根据搅拌液体致热装置的尺寸设计出海水蒸发室,并通过理论计算预估其在额定风速下的产水量约为239.1g/h,表明了风力致热海水淡化技术的可行性。Wind-powered seawater desalination is a way to firstly convert wind energy into thermal energy,and then use thermal energy to evaporate seawater for fresh water generation.A kind of windpowered seawater desalination device is introduced in this paper about its structure and working principle.The characteristics of S type vertical axis wind turbine,liquid-stirring heater and seawater evaporation chamber are described.Mathematical calculation of agitator diameter and other parameters of the liquid-stirring heater are carried out according to the driving torque of wind turbine.Evaporating chamber capacity for seawater is determined according to the size of liquid-stirring heater and the generated fresh water from the seawater desalination device under rated wind speed is estimated at 239.1 g/h,which verify the feasibility of this kind of wind-powered seawater desalination device.
