摘要：NOVELTY - This utility model relates to the chemical area, specifically relates to a material liquid distributing film-forming device. A material liquid distributing forming device used for falling film evaporation device, comprising film forming device main body, film-forming device main body from the upper part and lower part tube composed of tube, lower part of the heat exchange tube inner wall of pipe. Circle face outside lower part of tube from up to down provided with spiral with small and large spiral groove with groove to make the lower part tube out form one double weight guide with groove. Inner part of vertical tube equipped with material liquid storage pipe, a material liquid storage pipe extending to lower part of tube, the lower tube provided with the second vertical hole way, the second way hole is connected material liquid storage pipe. Rotating flow this new utility model solves the problem that the traditional spiral plug and distributing the function limited, when in small flow amount film distribution effect is not good the defect.
