Truss beam of tower appts.

Abstract

A support beam of truss in tower used for chemical industry is prepared as connecting truss main beam with truss sub beam by support structural unit, connecting two ends of truss main beam to support base and connecting it with wall of tower by debber, hanging two ends of truss sub beam in the air.

Description

technical field [0001] The invention mainly relates to a tower internal part in a chemical tower, in particular to a truss support beam for a large tower. Background technique [0002] In the departments of oil refining, petrochemical, fine chemical, food, medicine and environmental protection, towers are important unit equipment with a large volume and 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 unit operations such as distillation, absorption, extraction, washing, and heat transfer. Therefore, the research on towers has always been an important issue that scholars at home and abroad have generally 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 towers has continued to increase, and the requirements for t...

Problems solved by technology

Traditional support beams are mostly I-beam structures. In small towers, this I-beam structure is simple, takes up little space, and is easy to install. It has been widely favored for a long time. The disadvantages of using I-steel 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-steel beams are doubled , causing the beam to be too heavy and occupy a large space, seriously affecting the flow state and mass transfer effect of the gas-liquid two-phase in the tower
