Device and Method for Hydrolysis of Plant Hemicellulose by Fermentation of Citric Acid Wastewater with Shell and Tube Heat Exchanger
With the continuous breakthrough and innovation of production technology and modern science and technology
in China, it is of great significance to strengthen the research on functional and applicable production equipment.
Heat exchangers are used in many fields such as chemical production, mechanical pharmacy, etc. Among them,
shell-and-tube heat exchangers are important heat exchange equipment widely used in many industrial fields
such as petroleum, chemical industry, power, etc. Reasonable design of shell-and-tube heat exchangers can not
only improve heat exchanger performance, improve industrial production efficiency and economic benefits, but
also reduce energy consumption and save metal resource loss. Therefore, the purpose of this paper is to explore
the device and method for hydrolyzing plant hemicellulose with citric acid wastewater on the basis of studying
the working principle of shell-and-tube heat exchanger, analyze the application and modification of wastewater
treatment technology, and explore the advantages and disadvantages in the process of use. This article will use
the research method of specific analysis of specific problems to make data comparison and draw a conclusion.
Through theoretical innovation and exploration, we can find a suitable mode to promote the development of
hydrolyzed plant hemicellulose. The research results show that hemicellulose can be hydrolyzed by 42% by 1.4%
dilute sulfuric acid reaction in a fixed hydrolysis solution, thus effectively improving the use effect of citric acid
wastewater. Therefore, combined with the characteristics of citric acid wastewater, such as high pollutant
concentration, high temperature and good biodegradability of wastewater, the design method of shell-and-tube
heat exchanger is used to judge the influence of pre-hydrolysis time and pre-hydrolysis temperature on
hemicellulose in plant raw materials, analyze different application difficulties and explore development
prospects, thus proposing the implementation path of improving the method of hydrolyzing plant hemicellulose.
These theories are used to guide innovation and integration, providing valuable experience for the wide
application of nanotechnology
