Definitions

  • lnterfacial surface generating means which have, an inlet end adapted to receive fluid, and outlet end adapted to discharge fluid, and a plurality of separate passage ways connecting the inlet end and outlet end, the passage ways opening l on the inlet end essentially along a first line lying approximately through the center of the inlet end and (2) on the outlet end essentially along a second line lying approximately through the center of the outlet end the second line being essentially normal to the first line.
  • a plurality of the generating means can be used in series to make an interfacial surface generator which will produce man within a stream.
  • An interfacial surface generator is a static device which mixes fluids. Such mixing is obtained by division of a fluid stream into a plurality of substreams, recombination of the substreams into a main stream and subsequent division, repositioning and recombination until the desired degree of mixing is obtained.
  • Interfacial surface generators are known in the art and are disclosed, for example, in the following U.S. Pat. Nos: 3,015,452, 3,0l5,453, 3,182,965, 3,l95,865, 3,394,924, 3,404,869, and 3,406,947. They are further discussed in Harder, Challenges in Mixing Viscous Systems, Symposium 2e, 65th National Meeting of A.I.Ch.E. (I969); Pattison, Chemical Engineering, page 94 et seq. (May I9, 1969); and French Pat. No. 735,033.
  • the present interfacial surface generators are easily constructed from materials such as steel or plastic.
  • the generators are solid bodies having (i) an inlet end adapted to receive fluid, (ii) an outlet end adapted to discharge fluid, and (iii) a plurality of separate passage ways through the body connecting the inlet end and outlet end, the passage ways opening l) on the inlet end essentially along a first line lying approximately through the center of the inlet end and (2) on the outlet end essentially along a second line lying approximately through the center of the outlet end the second line being essentially normal to the first line.
  • FIG. 1 is a three-dimensional view of a single generating means.
  • FIG. la shows a side view from the left-hand side of the generating means of FIG. 1.
  • FIG. lb shows a side view from the right-hand side of the generating means of FIG. 1.
  • FIG. 2 is a three-dimensional view of another generating means.
  • FIG. 2a shows a side view from the left-hand side of the generating means of the generating means of FIG. 2.
  • FIG. 2b shows a side view from the right-hand side of the generating means of FIG. 2.
  • FIG. 3 is a partial cross section of generating means having securing means in the form of threads.
  • FIG. 4 shows an interfacial surface generator comprising two generating means confined with a pipe.
  • FIG. 5 is a front view of a preferred interfacial surface generator.
  • FIG. 6 shows the bottom view of the generator of FIG. 5.
  • FIG. 7 shows the top view of the generator ofFIG. 5.
  • FIG. 8 shows the left-hand view of the generator of FIG. 5.
  • FIG. 1 there is depicted a single generating means which is a solid body 1 in the form ofa cylinder having an inlet end 2 an outlet end 3, and four passage ways, 4, 5, 6, 7 through body 1.
  • the passage ways open on inlet end 2 essentially along line A-A (shown in FIG. 1a) which lies approximately through the center of the inlet end.
  • the passage ways open on the outlet end essentially along line B-B (shown in FIG. lb) which lies approximately through the center of the outlet end and which is essentially normal to line A-A.
  • the generating means used in this invention must contain at least two separate passage ways.
  • the generating means may have two, three, four or more separate passage ways. When the generating means contain four passage ways, as shown in FIGS.
  • the passage ways can connect the inlet end (FIG. Ia) to the outlet end (FIG. lb) via channels connecting inlet holes a, b, c, and d (FIG. la) to outlet holes a,, b,, c,, and 11, (FIG. lb) respectively.
  • inlet holes a, b, c, and :1 may be connected via a passage way to outlet holes a,, d,, b,, and 0,, respectively.
  • FIG. 2 shows an interfacial surface generating means 8 having an inlet end 9, an outlet end 10, and four passage ways ll, 12, 13, and 14 through generating means 8.
  • the passage ways open on inlet end 9 in a staggered manner essentially along line C-C (shown in FIG. 2a) which lies approximately through the center of the inlet end.
  • the passage ways open on the outlet end in a staggered manner essentially along line D-D (shown in FIG. 2b) which lies approximately through the center of the outlet end and which is essentially normal to line C-C.
  • the passage ways shown in FIGS. 2, 2a, and 2b connect inlet holes e,f, g, and h (FIG. 2a) to outlet holes e,,f,, g, and h, (FIG. 2b) respectively.
  • line AA and line C-C be exactly normal, i.e., to lines 8-8 and D-D, respectively.
  • the generating means shown in FIGS. I and 2 are cylinders. It should be recognized that other convenient shapes, such as cubes, can be used to make interfacial surface generators in accordance with this invention. Likewise it should be noted that while in the drawings, the cross section of the passage ways is circular, there is no reason why the cross section can not be any other convenient shape, such as square or triangular.
  • FIG. 3 is a partial sectional side view of a cylindrical interfacial surface generator means (dotted lines showing passage ways have been omitted) showing an inlet end 11 and an out let end 12.
  • Male threads 13 and female threads 14 are integral parts of the generator and serve to connect one generator to another and thereby form a series of generators. Such an arrangement provides an easy method for securing one generating means to another.
  • FIG. 4 Another interfacial surface generator is shown in FIG. 4 wherein two single generating means l5, 16 are securely held within pipe 17. A space must be provided between generating means 15 and 16 to permit flow of fluid. The optimum shape of such a space is a tetrahedral configuration because this shape minimizes the region in which material can hang-up." Such a configuration may be obtained by using a plurality of generating means such as that shown in FIGS. 5-8 (in which dotted lines have been eliminated in FIGS. 6 and 7).
  • FIG. 5 is a front view of a generating means.
  • FIG. 8 is a left-hand side view of the generating means.
  • FIGS. 6 and 7 show the bottom and top view of the generator in FIG. 5.
  • FIG. 4 operates in a manner similar to the apparatus shown in the above-identified U.S. patents. Two layers of fluid flowing downward become eight layers as the fluid flows through generating means 15 and eight layers of fluid leaving generator 15 increase to 32 layers upon flowing through generator 16. The size, configuration, and number of generating means used in a given situation will depend upon the particular circumstances.
