Introduction to fermentation broth wastewater treatment project:
The fermentation industry is a processing industry that uses grain and agricultural by-products as its main raw materials, mainly including citric acid, lactic acid, monosodium glutamate, liquor, starch sugar and other industries, and plays an important role in many industries. However, the wastewater pollution from the fermentation industry restricts the sustainable development of the fermentation industry. The wastewater mainly contains a large amount of organic substances such as lactic acid, citric acid, sugars, proteins, etc., and has characteristics of high concentration, high viscosity, difficulty in degradation, and strong acidity. Therefore, it is very necessary to develop efficient and energy-saving fermentation liquid wastewater treatment processes and equipment.
Fermentation wastewater treatment process:
Equipment centrifugal extractor working principle:
Mixed mass transfer process: light and heavy two-phase solution enters the lower mixing chamber in a certain proportion, and is mixed and dispersed from the wheel center inlet by the wheel agitating slurry and the dispersion slurry. At this time, the two-phase liquid is thoroughly mixed to make the solute from one phase. The liquid is transferred to another phase liquid to complete the mixed mass transfer process.
Separation process:
The mixed liquid is driven by the ribs in the lower rotating drum to rotate synchronously with the rotating drum, and enters the upper rotating drum via the annular baffle by the centrifugal suction of the upper rotating drum. In the drum, the mixture continues to drive the synchronous liquid to rotate synchronously. Under the centrifugal force field, the two phases are separated from each other. The heavy phase liquid of the specific gravity gradually moves away from the center of the drum toward the drum wall in the upward flow process; The phase liquid gradually moves away from the drum wall toward the center. Finally, the two-phase liquid enters the collection chamber through the respective seesaws and is taken out of the machine by the lead pipe to complete the two-phase separation process.
