Liquid distribution structure of a distillation equipment

Abstract

A liquid distribution structure for distillation equipment. The invention relates to the technical field of distillation equipment. The upper end of the top connecting pipe is connected through the lower wall of the steam pipe, and the upper and lower ends of the inclined pipe are integrally formed with threaded connection ends. The upper and lower ends of the connecting pipe are integrally formed with connecting internal threads on the inner ring walls, and the connecting internal threads are threadedly connected with the adjacent threaded connection ends, and a sealing ring is sleeved on the threaded connection ends of the connection; several inclined pipes and several The transfer pipes are arranged alternately and connected from head to tail; the upper end of the uppermost inclined pipe is connected to the lower end of the top connecting pipe, the lower end of the lowermost inclined pipe is connected to the upper end of the bottom connecting pipe, and the lower end of the bottom connecting pipe is connected to the discharge pipe The upper side wall is through-connected. When maintenance is required, the damaged part can be removed and replaced to save maintenance costs, and the direction of the pipeline can be adjusted to adapt to the installation of different distillation equipment shells, increasing the applicability of installation.

Description

technical field [0001] The invention relates to the technical field of distillation equipment, in particular to a liquid distribution structure of distillation equipment. Background technique [0002] Distillation is a thermodynamic separation process. It utilizes the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense them to separate the entire components. There are two types of evaporation and condensation. A union of unit operations. Compared with other separation methods, such as extraction, filtration and crystallization, its advantage is that it does not need to use other solvents other than the system components, so as to ensure that no new impurities will be introduced. [0003] The steam condensing pipes in the current distillation equipment are all in the form of an integral spiral disk inside the housing of the distillation equipment. Once a part of the pipeline is damage...

Problems solved by technology

[0003] The steam condensing pipes in the current distillation equipment are all in the form of an integral spiral disk inside the housing of the distillation equipment. Once a part of the pipeline is damaged, the entire pipeline needs to be replaced, which wastes resources and costs a lot for maintenance. Urgent improvement
