Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a reboiler with reasonable structure, safe and efficient operation, which can solve the problem of vibration failure of the tube bundle of the reboiler, and has high heat exchange efficiency and small flow resistance.
The reboiler has both the best heat transfer characteristics and the minimum flow-induced vibration, which overcomes the shortcomings of the existing reboilers, especially large reboilers, which cannot take into account the tube bundle vibration and heat transfer characteristics

Abstract

The invention discloses a mixed baffling stream type reboiler. The mixed baffling stream reboiler comprises a shell body and a support which is arranged at the lower part of the shell body and is used for supporting the shell body, shell side in-out ports are correspondingly arranged at two ends of the shell body, multiple groups of tube bundles are arranged at intervals in the axial direction of the shell body in the shell body, baffling stream plates and baffling stream fences are arranged in the radial direction of the tube bundles in the shell body, and the baffling stream plates and the baffling stream fences are used for supporting the tube bundles and conducting stream guidance on shell side fluid. The mixed baffling stream type reboiler is reasonable in structure and safe and efficient in work, and combines an optimal heat transfer property and a minimum flow-induced vibration property.

Description

【Technical Field】 [0001] The invention belongs to the technical field of process equipment in the petrochemical and energy industries, and specifically relates to a hybrid baffle reboiler, which is used for large-scale heat exchange equipment required for production in the petroleum, chemical, energy and other industries. 【Background technique】 [0002] As an important large-scale heat exchange equipment, the reboiler has a wide range of applications in petroleum, chemical, energy and other industries. In the petrochemical industry, its role is to heat and vaporize the liquid phase components at the bottom of the rectification tower to provide a suitable process medium for high-purity distillation and separation. In the design of the reboiler, it is not only necessary to meet the heat transfer characteristics required by the process, but also to consider the impact of tube bundle vibration on the long-term safe operation of the reboiler. Especially in the design of large-scale r...
