What are the structural characteristics of the vertical shell and tube heat exchanger?

The structural characteristics of the vertical shell and tube heat exchanger are reflected in the orthogonal heat transfer path design of the tube side and shell side fluids. The cylindrical pressure vessel is bounded by the tube sheet to form a dual-medium isolation cavity. The tube bundle array is arranged in a straight line in the direction of gravity. The corrugated surface of the baffle guides the shell side fluid to form turbulence to enhance convective heat transfer. The sealing structure of the tube box and the shell flange connection adopts an asymmetric wedge-shaped gasket to form a composite sealing mechanism of axial preload and radial constraint....

The industrial dmf distillation columns or towers will continue to be upgraded and improved

Recently, DMF (dimethylformamide) distillation towers or columns in the industrial field have become a hot topic of discussion. DMF is a commonly used organic synthesis solvent and chemical reaction solvent, but it presents certain challenges in terms of purity, stability, and safety. In order to improve the purity and safety of DMF, many enterprises have begun to adopt DMF distillation technology. The DMF distillation tower is a device that uses the principle of fractionation to separate impurities and DMF. These towers and columns play a crucial role in chemical production, ensuring the purity and safety of the processing flow. There are currently various forms and sizes of DMF distillation towers or columns on the market. According to different production and process requirements, towers and columns of different sizes and process parameters can be selected. For example, some companies can choose distillation towers with packing, while others choose to install plate towers. The use of DMF distillation equipment can not only improve production efficiency and product quality, but also help reduce harm to the environment and personnel. At the same time, it also meets the national requirements for chemical production safety and environmental protection. In the future, the market demand for DMF dis...
