Abstract

The invention relates to an air-lift type anaerobic bioreactor, and belongs to the technical field of bioelectronics equipment. The reactor comprises a reaction tank, a gas inlet pipe, a gas ejector pipe, a separator and a nitrogen tank. The separator is located at the bottom inside the reaction tank. The bottom of the reaction tank is provided with a sewage discharge outlet. The gas inlet pipe penetrates through the top of the reaction tank to extent to the bottom of the reaction tank. The gas ejector pipe is connected with the bottom end of the gas inlet pipe. The gas ejector pipe is horizontally arranged at the bottom of the reaction tank. A plurality of gas nozzles are uniformly formed in the gas ejector pipe. The middle of the top of the reaction tank is provided with an exhaust opening. A plurality of staggered baffles are further arranged inside the reaction tank. One edges of the baffles are fixedly connected to the reaction tank. According to the air-lift type anaerobic bioreactor, the staggered baffles are adopted for limiting the gas flowing direction, so that a solution inside the tank is stirred, and the stirring effect is generated; meanwhile, due to the staggered baffles, the gas speed is lowered, and liquid with the high viscosity can be sufficiently stirred.

Description

technical field [0001] The invention relates to an air-lift anaerobic bioreactor, which belongs to the technical field of bioelectronic equipment. Background technique [0002] Anaerobic bioreactors are generally used for reactions such as fermentation. The airlift bioreactor uses a gas-driven solution to replace the traditional mechanical agitation, which can effectively reduce the impact of the shear force of the agitation on the organism. However, the existing air-lift bioreactors all adopt direct ventilation, and the gas drives the liquid circulation through the diversion structure. When cultured at high density, the viscosity of the liquid increases and the circulation is slow, so the degree of mixing will be relatively poor. Contents of the invention [0003] The technical problems to be solved by the present invention are: to overcome the shortcomings of the above-mentioned technologies; to propose a non-circulating air-lift anaerobic bioreactor. [0004] In orde...
