Medium-sized high-mass-transfer circulating type ventilation fermentation tank

Abstract

The invention discloses a medium-sized high-mass-transfer circulating type ventilation fermentation tank, and relates to the technical field of biological fermentation. The medium-sized high-mass-transfer circulating type ventilation fermentation tank comprises a fermentation tank body, wherein a cooling injection pipe is arranged in the fermentation tank body; a circulating barrel is also fixedlyarranged in the fermentation tank body; openings are respectively formed in the top and the bottom of the circulating barrel; the bottom of the circulating barrel is also connected with a ventilationpipe; a first end of the ventilation pipe is arranged on the bottom of the inside of the circulating barrel; a second end of the ventilation pipe extends out of the fermentation tank body; the opening of the first end of the ventilation pipe is downward, and is connected with an air distribution head; the top of the air distribution head communicates with the first end of the ventilation pipe; the bottom of the air distribution head is closed; a side wall of the air distribution head is connected with a three-phase mixing rotator through a gas branch pipe; a feeding opening of the three-phasemixing rotator communicates with the gas branch pipe; and a discharging opening of the three-phase mixing rotator is positioned outside the circulating barrel. The medium-sized high-mass-transfer circulating type ventilation fermentation tank aims at providing good engineering conditions for ventilation biological reaction, completely removing mechanical stirring and improving the energy-saving effect in a fermentation process.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a medium-sized high-mass-transfer circulating ventilated fermenter. Background technique [0002] Almost all domestic fermentation industries such as antibiotics, vitamins, amino acids, and organic acids use general-purpose ventilated stirring reactor technology for industrial production. For decades, no major breakthroughs have been seen in fermentation equipment, and there have always been high energy consumption and ventilation in the fermentation process. The status quo of low oxygen utilization; [0003] In the fermentation industry, energy consumption (air oxygen supply, steam disinfection, stirring power consumption, circulating water cooling) accounts for 20% to 30% of the total product cost, and the stirring for fermentation accounts for 20% to 40% of the total energy consumption; The state of the fermentation process is analyzed in terms of fluid mechan...
