Problems solved by technology

However, its application has the following problems: H 2 Small density, difficult to liquefy, easy to leak, difficult to store and transport; CO is biologically toxic and has great potential safety hazards
The main feature of this patent is that the gas is broken up and mixed with the liquid when the gas is fed in. There is no requirement for the size and degree of dispersion of the bubbles, and it cannot effectively increase the gas residence time, nor can it fully mix the reaction materials with a relatively high solid concentration. It is only applicable to some Gas-liquid chemical reaction with fast reaction rate

Abstract

The invention discloses an integrated device for gas conveying and material stirring, which comprises a rotating stirring shaft and a motor; The connection between them is sealed; the stirring part of the rotating stirring shaft is equipped with a slanted blade disc turbine agitator, and the bottom end is equipped with a microporous aeration device; the shaft wall of the rotating stirring shaft in the buffer air inlet chamber is provided with ventilation The ventilation channel is arranged in communication with the microporous aeration device through the air inlet chamber provided in the rotating stirring shaft. The invention increases the buffer air intake chamber to reduce the impact on the microorganisms when the air intake velocity fluctuates, and uses a microporous aeration device to increase the contact area between fine air bubbles and microorganisms, and at the same time cooperates with a multi-layer oblique blade disc turbine agitator The material in the bioreactor can be circulated downward from the center and then upward along the inner wall around the main body of the bioreactor to strengthen the biotransformation process of the gas.

Description

technical field [0001] The invention relates to an integrated device for gas conveying and material stirring and a bioreactor comprising the device. Background technique [0002] with H 2 Synthesis gas with CO as the main component comes from a wide range of sources, including biomass pyrolysis gas, artificial gas, coke oven gas, etc. Its output is huge, and it can be used as fuel to relieve energy pressure, and has a good development prospect. However, its application has the following problems: H 2 Small density, difficult to liquefy, easy to leak, difficult to store and transport; CO is biologically toxic and poses a great safety hazard. will be H 2 The methanation of synthetic gas with CO as the main component into natural gas is not only easy to store, transport and use, but also improves safety, which is conducive to its popularization and application. [0003] Syngas methanation methods mainly include chemical, physical and biological methods. Among them, the che...
