Stirring device for gas-liquid mixing reactor with uniform mixing

Abstract

The invention discloses a stirring device for a gas-liquid mixing reactor with uniform mixing. The stirring device comprises a supporting seat, wherein the supporting seat is provided with a stirring paddle and a motor for driving the stirring paddle; the stirring paddle comprises a hollow shaft, a belt wheel, a pipeline rotating joint and a plurality of radial support pipes, wherein the hollow shaft is rotatably arranged on the supporting seat and is provided with a plurality of gas outlet holes; the belt wheel is fixed at the top of the hollow shaft and is linked with the motor; the pipeline rotating joint is arranged at the top end of the hollow shaft and is communicated with the inner part of the hollow shaft; the plurality of radial support pipes are fixed on the outer wall of the hollow shaft and are communicated with the inner part of the hollow shaft; and all the radial support pipes are respectively provided with one gas outlet hole. The stirring device disclosed by the invention has the advantages that in stirring, the stirring paddle can exhaust gas outwards and generates bubbles in surrounding liquid, the large bubbles under the flapping of stirring fins are crushed into small bubbles, the small bubbles stay in the liquid easily to facilitate gas-liquid mixing, and under the action of the stirring fins and the radial support pipes, the small bubbles can be easily diffused to all the parts.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a stirring device for a uniformly mixed gas-liquid mixing reactor. Background technique [0002] When performing material reactions in the chemical industry, material mixing is often involved. Usually, the materials are fully mixed by stirring to form a highly uniform mixture. [0003] In the prior art, the conventional raw material premixing process is mostly carried out by using a static mixer. However, since the static mixer usually has a fluid stagnation zone at the outlet, the flow velocity distribution of the material is uneven and the disturbance effect is poor, resulting in an unsatisfactory mixing effect. [0004] At present, a stirred tank mixer with a relatively complex structure is usually used as a raw material premixer. Among them, under the action of the stirring paddle, the degree of turbulence of the material increases, resulting in enhanced mixing effect. Ho...

AI Technical Summary

Problems solved by technology

However, when some gases are difficult to dissolve in the liquid, a large number of bubbles rise to the surface of the liquid before mixing, and the gas-liquid mixing effect is poor.
