Truss supporting beam for plate tower

Abstract

The invention relates to a truss supporting beam applied to a large-sized plate tower. The truss supporting beam applied to the large-sized plate tower comprises section steel beams, web pull rods, connecting plates, fixing rib plates and supporting components, wherein three section steel beams are connected with one another through the web pull rods; the web pull rods are connected with the connecting plates; the connecting plates are welded or connected onto the section steel beams through bolts respectively; the web pull rods are orderly arranged in a triangular form in sequence along the direction of the beams through the connecting plates and the section steel beams; the two ends of the section steel beam at a bottommost end are connected onto supports; meanwhile, the rest two section steel beams are connected with tower wall through the fixing rib plates. By using the truss supporting beam for the plate tower, which is provided by the invention, a supporting role is guaranteed; a headspace provided for overhaul and mounting can be greatly reduced while a horizontalness requirement is ensured; the height of the tower is lowered; the self weight of the supporting beam is lightened; moreover, by using the novel truss supporting beam, circulation areas of gas and liquid in the tower can be guaranteed; the transverse mixing of the gas and the liquid in the tower is increased; the flow resistance of a gas phase is reduced; the pressure drop in the tower is decreased.

Description

technical field [0001] The invention mainly relates to a tower inner in a chemical plate tower, in particular to a truss support beam applied to a large plate tower. Background technique [0002] In oil refining, petrochemical, fine chemical, food, medicine and environmental protection sectors, towers are important unit equipment with a large volume and a wide range, and their investment generally accounts for about 20% of the total investment, and some even as high as 50%. Columns are widely used in distillation, absorption, extraction, washing, heat transfer and other unit operations. Therefore, the research on towers has always been an important topic that scholars at home and abroad have paid attention to. [0003] In recent years, with the continuous development of tower technology, especially the continuous improvement of large-scale tower technology, the diameter of the tower has continued to increase, and the requirements for the technology of tower internals have b...

Problems solved by technology

Traditional support beams are mostly I-beam structures. In small towers, this kind of I-beam has a simple structure, takes up little space, and is easy to install. It has been widely favored for a long time. However, with the continuous increase of tower diameter Large, the disadvantages of using I-beams are becoming more and more prominent, especially in large towers over 7 meters, in order to ensure the requirements of levelness and deflection, the height and width of I-beams are doubled, The beam is too heavy and takes up a lot of space, which seriously affects the flow state and mass transfer effect of the gas-liquid two-phase in the tower
