本发明的一种太阳光导海水淡化装置的工作流程：真空泵16将淡化釜1抽成真空；海水泵4吸入海水后分为两路，一路作为冷却介质进入冷却管排2，吸收热量后排出系统，另一路作为淡化水源进入回热管排3，吸收淡化釜1内部水蒸气凝结热，温度升高后进入节能器9的壳程，吸收管程盐水热量继续升温后进入供液调节阀8；供液调节阀8根据釜内真空传感器7所测真空度调节进入淡化釜1的淡化海水量；采光架15平面正对太阳光，集光器14将投射到其表面的阳光汇聚后射入与其连接的光导管13内部，由于光导管内壁涂敷有高反射率涂层，光线几乎无损耗地传向末端，进入与之相连的光热转换管12，由于光热转换管内壁涂敷有高吸收率涂层，光能几乎全部转换为热能后透过管壁传入淡化釜1底部的海水之中，海水升温汽化后进入上部，经冷却管排2和回热管排3冷却降温形成凝结水（淡水）落入淡水槽17内，淡水液位传感器5检测到液位高限时便打开淡水泵6将淡水抽出，淡水液位传感器5检测到液位低限时关闭淡水泵6；海水蒸发浓缩后变成盐水，由盐水泵11抽出送入节能器9的管程，将热量传感壳程海水后排出系统，海水液位传感器10检测到液位高限时便打开海水泵11，海水液位传感器10检测到液位低限时关闭海水泵11。The working process of a solar photoconductive seawater desalination device of the present invention: the vacuum pump 16 pumps the desalination tank 1 into a vacuum; the seawater pump 4 sucks seawater and divides it into two paths, one path enters the cooling pipe row 2 as a cooling medium, and discharges the system after absorbing heat , and the other way is used as a desalinated water source and enters the heat recovery pipe row 3 to absorb the condensation heat of water vapor inside the desalination kettle 1, and enter the shell side of the economizer 9 after the temperature rises, and enter the liquid supply regulating valve 8 after the heat of the brine in the absorption tube side continues to rise; The liquid regulating valve 8 adjusts the amount of desalinated seawater entering the desalination tank 1 according to the vacuum degree measured by the vacuum sensor 7 in the tank; Inside the light pipe 13, because the inner wall of the light pipe is coated with a high-reflectivity coating, the light passes to the end almost without loss, and enters the light-to-heat conversion tube 12 connected thereto. High-efficiency coating, almost all the light energy is converted into heat energy and then passes through the pipe wall into the seawater at the bottom of the desalination tank 1.
