Rectifying column

Abstract

The invention provides a rectifying column, which comprises a barrel, a material feeding pipe component and a heating component, wherein the barrel comprises a barrel top oval end socket, a barrel bottom oval end socket and a plurality of middle connection sections; the barrel top oval end socket, the plurality of middle connection sections and the barrel bottom oval end socket are fixedly connected in sequence; the material specifications of the barrel top oval end socket and the barrel bottom oval end socket are higher than the material specification of the middle connection sections; the material feeding pipe component and the heating component are arranged on the lower end position in sequence along the vertical direction from the barrel top to the barrel bottom in the barrel; the barrel top oval end socket is provided with a column top gaseous phase outlet for outputting a gaseous phase matter after added materials are separated. Compared with prior art that the rectifying column wastes existing mineral resources, the rectifying column disclosed by the invention is characterized in that the material specification of the part of which the barrel strength is greatly weakened is high, the specifications of other parts of which the strength is slightly weakened are low, the own safety of the rectifying column is guaranteed, and meanwhile, the existing mineral resource used by the barrel is saved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a rectification tower. Background technique [0002] With economic development and social progress, energy conservation has become an inevitable and social consensus. As a developing country, China is facing the dual tasks of economic growth and environmental growth. At the same time, these two major tasks have negative effects on the development of mineral resources. . In order to protect the environment and achieve sustainable economic growth, changing the direction of energy development and saving this non-renewable mineral resource has become a virtue of every Chinese enterprise and every Chinese person. [0003] The rectification tower is a tower-type vapor-liquid contact device for rectification, and the above-mentioned mineral resources are needed in the production process. At present, in the production of chemical distillation towers, the cylinder part of the rectif...

AI Technical Summary

Problems solved by technology

At present, in the production of chemical distillation towers, the cylinder part of the rectification (stripping) tower equipment is designed according to the maximum amount of material in the tower, which is one size larger than the normal design of the steel plate or frame, so that Although it can guarantee the safety of equipment, it is a great waste of existing mineral resources, which runs counter to the policy of energy saving and consumption reduction advocated by our country.

[0004] The inventor found in the research that the rectification tower in the prior art has at least the following problems: the cylinder part of the whole rectification tower is designed with a steel plate or frame that is one size larger than the normal design, and there is a problem of waste of resources
