liquid distribution units forming thin films; chemical industry for evaporation of corrosive active liquids, hydrogen fluoride in particular. SUBSTANCE: liquid distribution unit is made in form of hollow cylinder located in circular space between vertical cylindrical heating surfaces whose upper end is secured in tube sheet and provided with circular pocket in upper portion; holes of similar diameter are made over circumference of part of cylinder and pocket at the same height; these holes are used for draining starting liquid over both surfaces of cylinder. EFFECT: intensification of evaporation process due to use of entire surface of evaporator; reduced corrosion due to avoidance of direct contact of liquid with heating surfaces. 1 dwg, 1 ex |
