  • a static mixing device for mixing a fluid As a static mixing device for mixing a fluid, a static mixer or the like is widely used.

Then, the fluid A is passed through other first through holes 22 that communicate with the above-mentioned first through holes 22, and is further passed through the first through holes 22 that communicate with the above-mentioned other first through holes 22. Finally, the fluid A flows out of the stacked member 2 through the first through holes 22 of the mixing elements 21a and 21b which are open to the outer circumferential surface of the stacked member 2.

  • a plurality of layers of flow paths along which the fluid A flows are provided in the direction in which the mixing elements 21a and 21b are stacked; in the example of Fig. 3(b) , two layers are provided. Since a plurality of flow paths that divide the fluid A in the direction in which the mixing elements 21a and 21b are stacked are provided, when the fluid A passes through the first through holes 22, as shown in Figs. 3(a) and 3(b) , the fluid A is divided in the direction in which the mixing elements 21a and 21b are stacked, and is thereafter combined. In other words, the flow of the fluid A is performed not only two-dimensionally in the radial direction such that the division and combination are performed planarly but also three-dimensionally while extending in the direction in which the mixing elements 21a and 21b are stacked.
  • the fluid A is highly mixed by repeating dispersion, combination, reversal, turbulent flow, eddying flow, collision and the like.
  • first through holes 22 of the mixing elements 21a and 21b are staggered, when the fluid flows from the above-mentioned first through holes 22 to other first through holes 22 on the upper and lower surfaces, the flow is easily divided or easily combined, and thus the fluid is efficiently mixed.
  • the fluid A may be made to flow in through the outer circumferential portion of the stacked member 2 of the mixing elements 21a and 21b and flow out through the inner circumferential portion.

Hence, the flow resistance to the fluid A flowing through the hollow portion 24 is smaller than that of the fluid A flowing within the stacked member 2, and the loss of pressure is also smaller. Therefore, even when a large number of mixing elements 21a and 21b are stacked, the fluid A substantially uniformly reaches the inner circumferential portion of the mixing elements 21a and 21b regardless of the position in the direction in which the mixing elements 21a and 21b are stacked, and substantially uniformly flows within the stacked member 2 from the inner circumferential portion to the outer circumferential portion.
  • the hollow portion 24 is provided, as compared with a case where there is no hollow portion 24, the fluid is more likely to enter the mixing unit 1a and to be passed to the first through holes 22. Likewise, the fluid entering the mixing unit 1a through the outer circumferential side thereof and passing through the first through holes 22 is made to smoothly flow out without being disturbed.
  • first through holes 22 of the mixing elements 21a and 21b whose upper surface and lower surface are in contact with other mixing elements 21a and 21 b within the mixing unit 1a, since the fluid A flows out from the above-mentioned first through holes 22 to the above-mentioned other first through holes 22 on the upper and lower surfaces, the fluid A is dispersed through the above-mentioned other first through holes 22 on the upper and lower surfaces. Moreover, since the fluid A flows in from the above-mentioned other first through holes 22 on the upper and lower surfaces to the above-mentioned first through holes 22, the fluid A from the above-mentioned other first through holes 22 on the upper and lower surfaces is combined. Therefore, significant mixing effects are acquired and the fluid A is highly mixed.
  • the first through holes 22 on both end surfaces in the stacking direction of the stacked member 2 are blocked by the removable first plate 3 and second plate 4, it is possible to separately produce the individual members.
