Background
In the current production of petroleum, fine chemical industry, biopharmaceuticals and other products, high-viscosity materials are gradually increased, and many high-molecular polymers and microbial polysaccharides all show high viscosity, and most materials are non-Newtonian fluids. In many polymer production processes, the viscosity of the material also changes, and therefore the stirring requirements are higher, and stirring is required to be able to adapt to each process of viscosity change. When the viscosity of the material is gradually increased, the flow is in a laminar flow state due to the influence of viscous force, the stirring action range is gradually reduced, and the high-viscosity liquid is still or flows slowly at the place away from the impeller, so that the solution is difficult to form integral circulation flow in the kettle. There are weak areas or dead areas in the kettle, which are very disadvantageous for mixing, dispersing, heat transfer and reaction of the materials. For normal stirring, the effect is very small only by increasing the stirring speed, because too high a speed can also form channeling inside the high mucus, and the liquid still remains stationary where it leaves the stirring paddles. In the process of fermenting the corresponding high-viscosity microorganisms, the microorganisms need to be introduced with air, and after the air is introduced, a cavity phenomenon is formed in the tank. In order to increase the stirring range, a helical ribbon type stirring paddle, a screw type stirring paddle or a universal stirring paddle is generally adopted for the working condition of high-viscosity liquid, but the problems of insufficient stirring effect, excessively high energy consumption and the like still exist.
The main problem faced by the stirring equipment of the existing high-viscosity material system is how to meet the process requirement and improve the efficiency, namely, the stirring equipment needs to minimize the consumed electric energy under the condition of fluid mixing and mass transfer which can meet the process requirement.
