Title: Double walled heat exchange jacket for reactors - made up of prefabricated elements joined up in situ.
IPC: B01J19/00
Filed: 1974-10-07
Abstract: Prefabricated elements which go together to form a double walled heat exchange jacket comprise a thick wall and a thin wall. The thick wall has on one face a series of parallel ribs separated by grooveS, the ribs being formed by machining grooves into the thick plate or by welding by diffusion a series of little bars on to the thick plate. A thin wall is then welded to the upper faces of the ribs by continuous diffusion produced by means of a conductor roller pressing down on the thin plate and passing over the faces of the ribs. After the thin plate is attached the element is cut to size and bent or pressed into shape according to the position it must take in the assembly. In position the elements are joined by welding the edges of adjacent elements to each other. The grooves can run in a direction parallel or perpendicular to the axis of revolution of the cylindrical shape that the assembly of elements forms. Each element can be made so that the grooves open out at each end to a collection header so that the elements when mounted in the assembly are supplied in parallel with the heating fluid. Alternatively each element can be connected in series so taht the inlet and outlet connection are coupled to the outlet and inlet connections respectively of the elements adjacent to it. Elements are suitable for vessels that a subject to heat exchanges by passing a heat carrying fluid along the wall, e.g. polymerisation reactors that first must be heated then cooled during the reaction. Provides a robust heat exchange jacket which has an efficient heat exchange system.
