摘　　要：搭建了低温三效水平管降膜蒸发器实验平台,测试了不同海水喷淋密度、蒸发温度和进料盐度条件下总传热系数、产水量和造水比等。研究结果表明:总传热系数随喷淋密度的增加呈现上升趋势,但随蒸发温度和盐度的升高均呈现下降趋势;实验系统的产水量随着喷淋密度和蒸发温度的增大而增大,对造水比影响较小;产水量和造水比随着盐度的增加而减少。A low temperature three-effect horizontal falling film evaporator was set up to test the total heat transfer coefficient,water yield and water production ratio under different spray density,evaporation temperature and feed salinity.The research results indicate that the overall heat transfer coefficient shows an increasing trend with the increase of spray density,but decreases with the rise in evaporation temperature and salinity.The water production of the experimental system increases with the increase of spray density and evaporation temperature,with a relatively minor impact on the water production ratio.However,both the water production and water production ratio decrease with the increase of salinity.
