Water vapor liquefying device

Abstract

The invention relates to a water vapor liquefying device. A plurality of tubular shells are arranged in a large-sized tubular shell; a first middle-sized tubular shell is horizontally arranged at a position, close to an edge part, of one end of the large-sized tubular shell; a first small-sized tubular shell arranged slantways is connected to one end of the first middle-sized tubular shell througha pipeline; a second middle-sized tubular shell arranged horizontally is connected to one end of the first small-sized tubular shell through a pipeline; a second small-sized tubular shell arranged slantways is connected to one end of the second middle-sized tubular shell through a pipeline; a vertical type tubular shell arranged vertically is connected to one end of the second small-sized tubularshell through a pipeline, and is close to an other end edge of the large-sized tubular shell. The water vapor liquefying device provided by the invention is simple in structure, achieves the aim of fully liquefying through maximum-area contact of water vapor and condensed water, prevents the vapor from entering a workshop or atmosphere, and further avoids the occurrence of a local high-temperature high-humidity environment.

Description

technical field [0001] The invention relates to the technical field of fermentation engineering, in particular to a steam liquefaction device. Background technique [0002] Fermentation engineering refers to a modern biotechnology method that uses microbial growth or metabolic activities to produce a large number of products needed by humans under good conditions. It is also called microbiological engineering. the result of. It mainly includes the selection of strains, the preparation of culture medium, the expansion of strains and the optimization of fermentation conditions. The industry has almost become a part closely related to people's daily life, and has more or less impact on the improvement and promotion of people's quality of life. It can be seen that fermentation engineering, as an indispensable biotechnology means , will play an increasingly important role in various industries in the future, and the impact will become more and more far-reaching.

Problems solved by technology

[0003] However, in the fermentation process, it is essential to eliminate the empty and actual sterilization of important parts of the tank such as the fermenter and the sterilizing filter. If any part of the fermenter is not sterilized thoroughly before fermentation, It means that in the subsequent fermentation, it is very likely that the feed liquid will be infected with miscellaneous bacteria, which will affect the level and quality of the entire fermentation, making it difficult for the final fermentation result to meet the expected requirements. It is also a crucial process

However, in the actual fermentation production, the process of empty sterilization and solid elimination will inevitably be accompanied by the use of a large amount of steam, and fermentation factories generally pass the steam directly through the pipe without liquefaction due to factors such as high processing costs and other factors. Because water vapor is a high-temperature and high-humidity gas, the consequence of direct discharge will often cause the workshop to be filled with fog, which to a certain extent interferes with the sight of the staff and affects their work enthusiasm and efficiency. At the same time, it will cause a large area of ​​water on the ground, equipment and products, and a large amount of water droplets on the doors and windows. If the discharge is not done properly, it will cause serious harm to the surrounding residents and workshop staff, and may even threaten their lives. Safety, in view of this, the development of a simple steam cooling device will have extremely important positive significance for the solution of this problem in terms of safety, economy, and environmental protection.
