Abstract
The invention discloses a high-shear mixer utilizing a hole-array micro-sized sleeve to reinforce mixing. The high-shear mixer comprises a cylindrical shell, a rotor, a stator and a main transmissionshaft, wherein a discharging port is formed in the cylindrical shell; a first feeding pipe is arranged in the center of the end wall of one end of the cylindrical shell; the top end of the first feeding pipe is arranged in a closed manner; a discharging hole array is arranged at a high shearing area; and a second feeding pipe, which is coaxial with the first feeding pipe and arranged outside the first feeding pipe in a sleeving manner, penetrates through the end wall. According to the invention, the high-shear mixer has the characteristic of high flux even if annular space size is in a micronscale; and compared with tubular feeding, the high-shear mixer has the advantages that the thickness of a material layer is greatly reduced, the mass transfer distance is reduced, and mixing and dispersing performances are improved. A micropore array enables a dispersed-phase material to be fully dispersed, so the mixing and dispersing performances of the high-shear mixer are improved. A continuous-phase material and the dispersed-phase material directly enter a high-shear stator and rotor area after cross-flow collision, so kinetic energy brought by the materials and energy of the high shearing area are fully utilized.
Description
technical field [0001] The invention belongs to the technical field of reaction equipment, and relates to a high-shear mixer for enhanced mixing with hole array micro-tubes, which is applied to fast chemical reactions. Background technique [0002] Micromixer is a new type of process intensification equipment. Due to the miniaturization of its characteristic size, it has large specific surface area, fast heat transfer and mass transfer rate, high safety, integration and controllability, small amplification effect and low energy consumption. With the advantages of low material consumption, it is widely used in various rapid mixing, emulsification, mass transfer, heat transfer and reaction processes. In the past ten years, the foundation, applied research and process technology development of microchemical technology have developed rapidly, and have become a typical example in the field of process intensification, and gradually formed a new discipline direction - microchemical...
