Description

Technical Field

[0001] The invention relates to the field of fluid processing, in particular to a static mixer. Background Art

[0002] A static mixer is a highly efficient mixing device without moving parts. Its basic working mechanism is to use a mixing unit fixed in a tube to change the flow state of the fluid in the tube, so as to achieve good dispersion and sufficient mixing between different fluids.

[0003] The mixing process of the static mixer is carried out by a series of mixing units of different specifications installed in the hollow pipe. Due to the action of the mixing unit, the fluid sometimes rotates left and sometimes rotates right, constantly changing the flow direction, not only pushing the central liquid flow to the periphery, but also pushing the peripheral fluid to the center, thus creating a good radial mixing effect. At the same time, the rotation of the fluid itself also occurs at the interface where the adjacent components are connected. This perfect radial circulation mixing effect enables the materials to be mixed evenly.

[0004] The current static mixer has high fluid energy consumption, and has many dead corners in the mixing process, which can easily cause pipeline blockage. It is not suitable for miniaturization, which brings inconvenience to subsequent processes. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a static mixer.

[0006] To achieve the above-mentioned purpose and other related purposes, the first aspect of the present invention provides a static mixer, which at least includes: a hollow mixer body, in the length direction of the mixer body, a liquid inlet and a liquid outlet are provided, and between the liquid inlet and the liquid outlet, a plurality of mixing units are sequentially connected and arranged in the mixer body, and the mixing units are hollow prisms.

[0007] The static mixer is used for fluid mixing.

[0008] A second aspect of the present invention provides a method for mixing fluids, which uses the aforementioned static mixer for mixing.

[0009] As described above, the static mixer of the present invention has the following beneficial effects:

[0010] The static mixer of the present invention has low fluid energy consumption, is not likely to cause pipeline blockage, is suitable for miniaturization, and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS
