Supergravity-fractal impact bed reactor

Abstract

The invention discloses a supergravity-fractal impact bed reactor. The supergravity-fractal impact bed reactor mainly comprises a cylindrical outer shell and a rotary cylinder assembled by a pluralityof fractal circular ring pieces; a tray is arranged under the rotating cylinder; and the tray is connected with an external centrifugal machine. The supergravity-fractal impact bed reactor is characterized in that a feeding hole is formed in the center of the rotary cylinder; the cylindrical shell is provided with a fluid outlet pipe; the fractal circular ring pieces are internally provided withfractal channels which are through stage by stage in the radial direction; the fractal stage n of the fractal channels inside the fractal circular ring pieces is smaller than or equal to 15 and largerthan or equal to 3, and the diameters of the fractal channels are in a range from 1 micron to 0.5 meter; the diameter of the fractal channel of n-1 stage is 1.2-2 times of the diameter of the fractalchannel of n stage, so that the distribution force of the inner side channels is prevented from being insufficient; and the flow of a fluid in the channels can be adjusted by adjusting the rotating speed of the cylinder. A centrifugal force is adopted as power to drive the reactor, ordered and repeated instant impact mixing and dispersion among fluids in a supergravity field are realized, and disorder mixing among the fluids in filler of a supergravity device is greatly improved.

Description

Technical field: [0001] The invention belongs to the technical field of chemical equipment, and relates to a reaction device suitable for mixing and reacting multiphase flows such as liquid-liquid and liquid-solid, which can satisfy the rapid reaction process controlled by microscopic mixing and the interaction between two (multiple) components. Various unit operations such as mass transfer and heat transfer, especially a reaction device that can realize forced mixing of solid-phase materials or high-viscosity materials. Background technique: [0002] Multiphase flow mixing and reaction is a common chemical process in many fields such as chemical industry, energy, environment, biochemistry, etc. Good uniform and rapid mixing performance is an important indicator to determine the performance of the reactor, which directly affects the production intensity, conversion rate and product quality. Traditional multiphase flow mixing often uses mechanical stirring, fluid atomization,...

AI Technical Summary

Problems solved by technology

However, these reaction devices with fractal structures inevitably have narrow flow channels, which make industrial scale-up difficult, and it is difficult to handle systems with high-viscosity materials and solid-phase materials; pressure is used as the driving force, and small-diameter flow channels are easily blocked by equipment. damage
