Bio-fermentation industry is the use of biological life activities of the enzyme, enzyme processing of inorganic or organic raw materials, industrial products production technology. In recent years, the rapid development of fermentation industry, however, the treatment of fermentation wastewater is difficult. Therefore, the low cost of biological fermentation wastewater treatment has become one of the main factors in fermentation industry development.For the waste problem of the Lysine fermentation difficult to deal with, This topic researched Lysine fermentation waste near-zero emissions by drying and granulation of large continuous fluid bed,which is applied on drying of Lysine fermentation waste, it can directly and continuously get dense spherical particulate produce from liquid material by spraying, granulation, drying and cooling in the fluidized bed, and simultaneously solve the problem of environmental pollution, waste of resources and high production cost,caused by fermentation waste. achieving near-zero emissions of fermentation waste, achieving the cleaner production of lysine fermentation industry.This article consists of four parts, The first part gives Summary about the current handling of lysine fermentation waste and fluid bed granulation drying techniques; the second part provides theoretical support for continuous large-scale industrialization through balance accountancy of heat and mass; the third part provides practical basis and foundation for industrial applications by small scale experimental study; The fourth part improves some key structures and new technology for the production and manipulation of the whole system, and the application of the DCS integrated control further improves the automation and better continuous control of the system, In addition, the comparison of key parts of the system had been done between this system and abroad, this part analyzed its economic and social benefits finally.This technology of Lysine fermentation liquid near zero emissions of large continuous fluidized bed granulation and drying has reached even better than foreign technology, it has break the foreign monopoly and blockade on the drying technology and equipment of lysine fermentation, even promote industrialization process of clean production of the domestic lysine fermentation industry. |
