Abstract

The invention relates to an air-liquid dual injection type airlift loop reactor comprising a fermentation tank. The air-liquid dual injection type airlift loop reactor is characterized in that guide cylinders are arranged in the fermentation tank, a liquid ascending area is arranged inside each guide cylinder, a liquid descending area is arranged among the guide cylinders and the fermentation tank, an annular distribution pipe is mounted on the lower portion of the liquid ascending area and provided with a plurality of spray holes, one or more static spiral cutting devices are mounted at the bottom of the fermentation tank, and each static spiral cutting device is provided with an air-liquid mixture outlet, a fermentation liquid input inlet and a compressed air input inlet, wherein the compressed air input inlet is connected with an air source, the air-liquid mixture outlet is connected with the distribution pipe, and the fermentation liquid input inlet is connected with a circular liquid outlet in the bottom of the fermentation tank through a pipeline. The air-liquid dual injection type airlift loop reactor has the advantages that difficulties in mixed air-liquid delivery and air-liquid coupling of an airlift biological fermentation system are overcome, biological treatment capability of the airlift loop reactor can be given to full play maximally, treatment efficiency is improved and energy consumption is reduced.

Description

technical field [0001] The invention relates to a gas-liquid double-jet airlift loop reactor, in particular to a gas-liquid double-jet airlift loop reactor based on gas-liquid micro-nano cutting and refining technology. Background technique [0002] The airlift loop reactor (ALR for short) is a reactor that uses a gas source as power to make liquids mix and circulate. It is the most widely used biological reaction equipment at present. Its working principle is to inject sterile air into the fermentation liquid through nozzles or spray holes, and the air bubbles are divided into fine pieces by the turbulent flow of the gas-liquid mixture, and at the same time, due to the decrease in the density of the formed gas-liquid mixture, it moves upward, and the gas holdup The small fermented liquid sinks to form a circular flow to realize mixing and mass transfer of dissolved oxygen. This type of reactor has the advantages of simple structure, low energy consumption, small shear str...
