Abstract
Description
[Technical field]
[0001] The invention relates to a mixing unit, in particular to a mixing unit for enhancing mass transfer and heat transfer. [Background technology]
[0002] Mixing is the process of mass and heat transfer of the mixed medium. In situations where various types of media need to be mixed, a mixer is a commonly used mixing unit device. According to the principle, it can be divided into static mixers and dynamic mixers. Compared with stirring type dynamic mixing equipment, static mixers have no moving parts and do not rely on rotating stirring mechanical movement to mix the fluid. Instead, they use the mixing unit set inside the equipment to make the mixed fluid continuously guided by the mixing element during the flow process, and then produce or self-rotation, or shear separation, or motion collision, etc., to achieve the mixing effect. Therefore, the performance of the static mixer is mainly determined by the performance of the mixing unit inside it, and the existing static mixer mixing units, such as SV, SK, SX, SL, SH and other mixing units listed in JB / T7660, all have the following main problems: 1. The mixing process is mostly laminar flow, that is, the fluid in a certain area is still in this area after passing through the mixing unit; 2. The mixing effect is poor, that is, the fluid and the area are not evenly mixed; 3. The mixing pressure drop is large. Due to the structure of the mixing unit, the medium needs to consume a large amount of kinetic energy to achieve the mixing effect when flowing through the mixing unit, which means a large mixing pressure drop. Therefore, in order to solve the above problems, providing a mixing unit that can achieve better mass transfer and heat transfer effects is a long-term technical demand of those skilled in the art. [Summary of the invention]
[0003] In order to overcome the shortcomings of the background technology, the present invention provides a mixing unit for enhancing mass transfer and heat transfer. By designing a special flow-guiding structure, the effect of fully mixing the upstream fluid medium is achieved. While achieving sufficient mixing, the mass transfer and heat transfer of the mixed medium are enhanced.
[0004] In order to achieve the above-mentioned purpose of the invention, the present invention adopts the following technical solution:
[0005] A mixing unit for enhancing mass transfer and heat transfer comprises an inner guide plate, an intermediate guide plate and an outer guide plate. Each mixing unit is composed of four inner guide plates, four intermediate guide plates and four outer guide plates connected to each other. The formed mixing unit forms four independent flow channels. The peripheral flow of the upstream fluid is guided to the center after passing through the mixing unit, and the center flow of the upstream fluid is guided to the periphery after passing through the mixing unit, so as to fully enhance the mass transfer and heat transfer.
[0006] The inner guide plate is a plate or board structure with four edges.
[0007] The preferred shape of the inner guide plate is a diamond shape.
[0008] The middle guide plate is a plate or board structure with three sides.
[0009] The preferred shape of the intermediate guide vane is a triangle or a quarter cone with three sides.
[0010] The outer guide plate is a plate or a board structure with four sides.
[0011] The outer guide plate preferably has a shape of three straight sides and one arc side or a quarter-circular table shape with four sides.
[0012] The inner guide plate, the middle guide plate and the outer guide plate are connected to each other by welding or bonding.
[0013] By adopting the above technical solution, the present invention has the following advantages:
[0014] By designing a special flow-guiding structure, the peripheral flow of the upstream fluid is guided to the center, and the central flow of the upstream fluid is guided to the periphery, so as to achieve the effect of efficient mixing in the shortest mixing process, that is, to strengthen the mass transfer and heat transfer effect of the mixed medium. At the same time, the present invention also has the advantages of simple structure, easy processing and manufacturing, low production cost, good use effect, and is suitable for large-scale promotion and application.

[0023] Combined with Figure 1 and attached Figure 2 The mixing unit for enhancing mass transfer and heat transfer comprises an inner guide plate 01, an intermediate guide plate 02 and an outer guide plate 03. Each mixing unit of the mixing unit is composed of 4 inner guide plates 01, 4 intermediate guide plates 02 and 4 outer guide plates 03 connected to each other. The formed mixing unit forms 4 independent flow channels, which guide the peripheral flow 12 of the upstream fluid to the center after passing through the mixing unit, and guide the central flow 11 of the upstream fluid to the periphery after passing through the mixing unit, so as to fully enhance the mass transfer and heat transfer.
[0024] The inner guide plate 01 is a plate or a board structure with four edges.
[0025] The preferred shape of the inner guide plate 01 is a diamond shape.
[0026] The middle guide plate 02 is a plate or a board structure with three sides.
[0027] The preferred shape of the intermediate guide plate 02 is a triangle or a quarter cone with three sides.
[0028] The outer guide plate 03 is a plate or a board structure with four sides.
[0029] The preferred shape of the outer guide plate 03 is a shape with three straight sides and one arc side or a quarter-circular table shape with four sides.

When the mixed medium fluid from the upstream enters the mixing unit, it is divided into a central flow 11 and a peripheral flow 12 with reference to the center line of the pipeline end surface. When flowing through the mixing unit, after being guided by the formed flow channel, the peripheral flow 12 is located at the center of the pipeline when leaving the mixing unit, and the central flow 11 is located at the periphery of the pipeline when leaving the mixing unit, that is, the central fluid and the peripheral fluid of the mixed medium fluid are exchanged, that is, the mixing effect is achieved, and in this mixing process, the effect of fully enhancing mass transfer and heat transfer is achieved.
