A static mixer for liquid-liquid mixed emulsification and its working method

Abstract

The invention discloses a static mixer for liquid-liquid mixing and emulsification and a working method, comprising a mixer body, one end of the mixer body is provided with at least two liquid inlets, and the other end of the mixer body is provided with The liquid outlet is provided with a corrugated plate between the liquid inlet and the liquid outlet, and the corrugated inclination directions between adjacent corrugated plates are different, and grooves are distributed on the wall surface of the corrugated plate. The present invention arranges grooves on the wall of the corrugated plate of the static mixing unit, which can make the net drag reduction reach 8%; the existence of the micro grooves in the present invention changes the interface contact between the fluid and the mixer corrugated plate surface, increases The contact angle of the fluid on the surface of the material is improved, thereby changing the hydrophobicity of the surface of the corrugated plate; in addition, the micro-groove structure can reduce the convergence of small eddies in the boundary layer, delay the separation of the boundary layer, and reduce the energy loss of wall turbulence.

Description

technical field [0001] The invention relates to a static mixer, in particular to a static mixer for liquid-liquid mixing and emulsification and its working method, which is mainly used in liquid-liquid mixing in the production processes of petrochemical, daily chemical and energy. In the chemical process of homogeneous mixing and emulsification, etc. Background technique [0002] Homogenization is a technology often used in the production of food or chemical industry. Homogenization in food processing means that the material liquid of the material is refined under the triple action of extrusion, strong impact and pressure loss expansion, so that the materials can be mixed more evenly. For example, a homogenizer is used in dairy product processing. Make the fat in the milk more finely broken, so that the whole product system is more stable. Milk will look whiter. Homogenization is mainly carried out by a homogenizer. It is an important processing equipment in the food, da...

Problems solved by technology

However, the disadvantage of this kind of mixer is that the resistance is relatively large during the mixing process.

[0008] In addition, in the current general chemical process applications, most of the mechanical mixing and static mixers are connected in series. The mechanical mixing equipment consumes a lot of power, the work process is discontinuous, the working medium is not closed, and the failure rate of the mechanical mixing equipment is high. In some special processes In the process, the occurrence of faults directly leads to the danger of chemical production
