Abstract

The invention relates to a liquid-liquid heterogeneous mixing-reaction-separation integrated short-contact cyclone reactor, belongs the field of liquid-liquid heterogeneous mixing equipment, and particularly relates to a short-contact cyclone reactor integrating mixed reaction and separation. The reactor is characterized in that a light phase liquid inlet pipe (3) is arranged at one side of an outer barrel (4), a material circulating structure (9) for communicating an inner cavity of an inner barrel (5) with an annular cavity is arranged on the wall of the inner barrel (5); a light phase overflow outlet pipe (1) is arranged on the inner upper part of the inner barrel (5) in a sleeving manner, an annular mixing cavity is formed between the light phase overflow outlet pipe (1) and the inner barrel (5), the upper part of the light phase overflow outlet pipe (1) extends out of the inner barrel (5), and a heavy phase underflow out pipe (7) is fixedly arranged on the lower part of the inner barrel (5) in a sleeving manner by a conical pipe (6). According to the invention, the integrated process of quick mixing, quick reaction and quick separation of heterogeneous liquid is realized, the equipment structure is compact, the handling capacity is large, continuous operation is realized, and the reactor has the advantages of being low in maintenance cost and strong in adaptability.

Description

technical field [0001] The invention relates to a short-contact swirl reactor integrated with liquid-liquid heterogeneous mixing, reaction and separation, which belongs to the field of liquid-liquid heterogeneous mixing equipment, and specifically relates to a short-contact swirl reactor integrating mixing, reaction and separation. Background technique [0002] The liquid-liquid heterogeneous reaction process is widely used in petrochemical, biological reaction, environmental protection and other engineering fields. One of the keys to the liquid-liquid heterogeneous reaction is to achieve efficient mixing and full contact between the liquid and liquid phases, and to achieve complete separation of the two phases. reaction and increase the reaction rate. [0003] Generally speaking, the mixing process is through bulk diffusion, eddy current diffusion, and molecular diffusion under the action of forced convection, and finally achieves uniform mixing at the molecular level.

Problems solved by technology

However, due to the limitations of the reactor equipment, the time scale of mixing is between several minutes or even several hours, and it is often used in reaction systems with slow reaction rates.

[0004] Moreover, for part of the reaction process, with the prolongation of the reaction time and the deepening of the reaction degree, secondary reactions will occur, resulting in non-target products, which seriously reduce the economical efficiency of the system.
