Abstract

The invention provides a biological reaction device and a biological reaction method, the biological reaction device comprises a shell, a stirring module and a jet flow module located at the bottom ofthe shell are arranged in the shell, the stirring module comprises a stirring shaft extending into the shell, and at least one radial flow paddle and at least one axial flow paddle are arranged on the stirring shaft. The biological reaction method comprises the steps that reactants are injected into the shell, the stirring module is started to perform stirring reaction on the reactants, and gas generated by the reaction enters the jet flow module through a circulating pipeline and is jetted into the shell through the jet flow module. By combining the jet module and the stirring module, mass transfer and heat transfer are better achieved, the reactants are fully mixed and react, the gas circulates in the reaction device through the circulating pipeline, the production efficiency of the biological reaction device can be effectively improved, and the biological reaction device has the advantages of being low in cost, small in occupied area, easy to maintain and the like and can be applied to the fields of food, medicine and the like.

Description

technical field [0001] The invention belongs to the technical field of biological reaction, relates to a biological reaction device, in particular to a biological reaction device and a biological reaction method. Background technique [0002] As an emerging technology, bioreactor technology has shown great economic and social value, for example, anaerobic fermentation treatment of municipal sludge wastewater, production of beer and various antibiotics, and use of fermentation reactors to treat solid waste. Traditional bioreactors have problems such as low equipment yield, large energy consumption, and slow reaction rate. When the stirring is insufficient, it is easy to cause local temperature to be too high, resulting in deterioration of the reactants, or the inability to fully mix the air and the fermentation broth. Ensure the supply of dissolved oxygen required for microbial growth and metabolism. In addition, the manual discharge of existing fermentation tanks is time-co...
