Abstract

The invention relates to liquid continuous impact flow heterogeneous reaction and aerobic fermentation technical equipment comprising a vertical drum 1 with a pot-shaped or cone-shaped bottom, upper and lower guiding cylinders 2, upper and lower propellers 3 and 4 with opposite spiral directions and a gas distribution ring tube 12 with a porous wall, wherein the center of the bottom of the vertical drum 1 is provided with a discharging tube 6; the upper and lower guiding cylinders 2 are vertically and coaxially installed in a reaction volume region of the drum 1; the upper and lower propellers 3 and 4 with opposite spiral directions are respectively and coaxially installed in the two guiding cylinders 2; and the gas distribution ring tube 12 with the porous wall is installed below the lower guiding cylinder 2 and connected with an air inlet tube 13. The liquid continuous impact flow heterogeneous reaction and aerobic fermentation technical equipment is suitable for various biomass aerobic fermentation and gas-liquid phase and gas-liquid-solid three-phase reaction processes taking liquid as a continuous phase, and has the remarkable advantages of excellent mixing contact among different substances, secondary diffusion of bubble impact flow, increased gas-liquid phase interface area, prolonged gas residence time, very low power consumption, energy saving and the like.

Description

[0001] Invention name: [0002] Liquid continuous impingement flow heterogeneous reaction and aerobic fermentation technology equipment. Technical field: [0003] It belongs to chemical and biochemical process equipment. It is suitable for various biomass aerobic fermentation, gas-liquid phase reaction and gas-liquid-solid three-phase reaction process with liquid as the continuous phase. Background technique: [0004] In food, light industry, medicine and other industries, there are many products such as monosodium glutamate, penicillin, etc., which are produced through the method of biomass aerobic fermentation. Aerobic fermentation is a gas-liquid-solid three-phase biochemical reaction process. In addition, in various process industries such as chemical industry, petrochemical industry, light industry, and medicine, many products are produced by gas-liquid phase reaction or gas-liquid-solid three-phase reaction with liquid as the continuous phase. These types of reactio...

AI Technical Summary

Problems solved by technology

Although widely used at present, the bubbling stirred reactor has the following disadvantages: (1) the mixing state, especially the liquid phase microscopic mixing state, is poor, and the reaction efficiency is not high; (2) the gas-liquid phase contact area is small, and the transfer speed is not fast. The speed of chemical or biochemical reactions is limited; (3) the power consumption of the stirring paddle is large, and the energy consumption is high; (4) the residence time in the gas reactor is short, and the gas consumption is too large
