Abstract
Кожухотрубный теплообменник, содержащий кожух и размещенные в нем два пучка U-образных теплообменных труб, подключенных к цилиндрическому коллектору, разделенному перегородкой на входную и выходную секции, и компенсаторы температурных расширений, расположенные в зоне соединения коллектора с кожухом, отличающийся тем, что, с целью интенсификации теплообмена и повышения эксплуатационной надежности, перегородка установлена поперек коллектора и U-образные трубы в каждом пучке расположены симметрично относительно ее плоскости, коллектор снаружи заключен с образованием буферной зоны в полый обтекатель в виде шестигранной призмы, два противолежащие ребра которой размещены в осевой плоскости кожуха, а боковые параллельные грани имеют ширину, равную глубине пучков, каждая секция коллектора снабжена вогнутыми перфорированными пластинами, примыкающими к торцам труб обоих пучков и имеющими отверстия ступенчато возрастающего от центра пучков к их периферии диаметра, причем компенсаторы выполнены в виде параллельно расположенных кольцевых мембран.A shell-and-tube heat exchanger comprising a shell and two beams of U-shaped heat-exchange tubes placed in it, connected to a cylindrical collector divided by a partition into the inlet and outlet sections, and expansion joints located in the zone of the collector-to-shell connection, characterized in that intensification of heat exchange and increase operational reliability, the partition is installed across the collector and the U-shaped tubes in each beam are located symmetrically relative to its plane, the collector the outside is enclosed with the formation of a buffer zone in a hollow fairing in the form of a hexagonal prism, two opposite edges of which are placed in the axial plane of the casing, and the side parallel faces have a width equal to the depth of the beams, each section of the collector is equipped with concave perforated plates adjacent to the pipe ends of both beams and having openings of a stepwise increasing diameter from the center of the beams to their periphery, and the compensators are made in the form of parallel-arranged annular membranes.
