摘　　要：本文提出一种在板式自由流降膜蒸发器中使用的梯形加热元件 ,可使得加热元件上、下端的液膜厚度保持一致 ,避免了壁面的干涸现象 ,极具实用价值。A trapezoid heating element used in plate film evaporator was presented in this article. When the heating element was used, the thickness of the liquid film was well-distributed at the top and bottom end of the plate so that the element is valuable to avoid the dry wall.
