Abstract

The invention discloses an impinging stream high-shear reactor for liquid-liquid quick mixing and reaction, which comprises a cylindrical reactor shell, a rotor, a stator and a main drive shaft, wherein the center of an end wall at one end of the reactor shell is provided with a first feed pipe; the end of the first feed pipe, which is positioned in the reactor shell, is a dead end; a discharge port of the feed pipe is arranged near the dead end; a second feed pipe is arranged around the first feed pipe; the discharge port of the second feed pipe is positioned in the reactor shell and opposite to the discharge port of the first feed pipe; the dead end of the first feed pipe is movably connected with the main drive shaft through a bearing; the main drive shaft is provided with a rotor base connected with the rotor; the stator is arranged on the internal surface of the reactor shell or arranged on the internal surface of the reactor shell through the stator base; the stator meshes with the rotor; and a discharge port of the reactor is arranged on the other end of the reactor shell. The reactor of the invention has the advantages of favorable mixing effect, low equipment investment and convenient heat exchange, and can not easily produce blocking.

Description

technical field [0001] The present invention relates to an impingement flow high shear reactor, in particular to an impingement flow high shear reactor which can be used for rapid mixing and reaction of two-component or multi-component liquid-liquid. Background technique [0002] Liquid-liquid mixing is an important chemical process, and its effect is particularly important for fast liquid-liquid reaction systems. For example, in the process of preparing ultra-fine powder by liquid-liquid two-phase precipitation reaction, the effect of liquid-liquid mixing directly affects the particle size and distribution of particles; the liquid-phase reaction system conducts complex rapid parallel competition reactions or serial reactions. During the competitive reaction, the effect of rapid liquid-liquid mixing greatly affects the yield and quality of the target product, and may have an impact on the design, optimization and operation of the entire production process.
