Manifold for a shell-and-tube heat exchanger for large product pressures, fabrication methods for a shell and tube heat exchanger having such a manifold, and use of a shell-and-tube heat exchanger for high product pressures with such a manifold in an atomization dryer

摘要

The invention relates to a circular cross-section manifold (1) with a deflection angle of 180 degrees for a high product pressure shell and tube heat exchanger (100) having first and second flanges (2; 3) at each inlet (E) and outlet (A ) of the manifold (1) and a manufacturing method for one and a shell and tube heat exchanger (100) having such a manifold (1), and the use of a high product pressure shell and tube heat exchanger (100) with such a manifold (1) in a spray drying plant. It is an object of the present invention to provide a manifold for a tube bundle heat exchanger for large product pressures, which has the necessary strength and sustainable dimensional stability and can be optimized in terms of flow during its production, so that the manifold losses and the tendency to product deposits are minimized and a good cleanability is given in the flow. This is achieved for a manifold (1) inter alia by: • that the manifold (1) consists of two, each integral manifold halves (1.1, 1.2), • that each manifold half (1.1, 1.2) at its the flange (2, 3 ) facing away from a junction (V), • that the manifold halves (1.1, 1.2) at the associated connection point (V) are materially interconnected, • that the course of the passage cross sections of each manifold half (1.1, 1.2) is formed by rotationally symmetric passages, of which at least one on the one hand from the flange (2, 3) and at least one on the other hand from the associated connection point (V) in each case coaxial arrangement on axes of rotation (X1.1, Y1.1, X1.2, Y1.2) extend, and • that the first and the second axis of rotation (X1.1, Y1.1) of the passages of the first manifold half ...
