Description

[0001] MULTI PIPE FLOW MIXING DEVICE [0002]

The present invention relates to a pipe mixing apparatus for enhancing the mixing effect of two fluids in a confluent pipe when different pipes merge.

A piping mixer is a device that mixes two fluids in a confluent pipeline where two fluids of different temperature, composition, or concentration meet and enter, and can be divided into a mechanical mixer and a static mixer. Mechanical mixers are made by mixing using dynamic components, and static mixers are made by mixing by flow design without dynamic components.

 Cracks due to thermal stress may occur in a Y- or T-shaped mixing tee in which fluids of different temperatures are mixed and crossed.

A low temperature fluid having a large flow rate and a low temperature can be introduced into the first pipe 11. The first fluid 1 shown in FIG. 2 flows from one side (left in the figure) to the other (right in the drawing) along the first straight pipe 11 as a low temperature fluid.

The second pipe 12 is a pipe into which the second fluid 2 flows. A high temperature fluid having a low flow rate and a high temperature can be introduced into the second pipe 12. The second fluid 2 shown in Fig. 2 flows from one side (upper side in the drawing) to the other side (lower side in the drawing) along the second straight pipe 12 as a hot fluid.

The third pipe 13 is a pipe through which the third fluid 3 flows. The third fluid 3 means a fluid in which the fluids of the first pipe 11 and the second pipe 12 are combined and mixed. At this time, the first fluid (1) and the third fluid (3) can flow in the same direction.

The first pipe 11 and the second pipe 12 meet at the mixing structure 100 and the third pipe 13 at the downstream side of the mixing structure 100 extends to the same diameter as the first pipe 11 . 2 to 4 are merely examples in which the first pipe 11 and the third pipe 13 extend by the same diameter, and the same diameter is not necessarily applied.

The second pipe 12 is arranged in a direction intersecting with the first pipe 11. The first pipe 11 shown in FIG. 2A is arranged in the horizontal direction, the second pipe 12 is arranged in the vertical direction, and the third pipe 13 is arranged in the same straight line as the first pipe 11 , And the mixed structure 100 may have a T shape. 2 or 4 is merely an example in which the first pipe 11 and the second pipe 12 form a T-shape, and it is not necessary to apply the T-shape, and various other shapes As shown in FIG.

The mixing structure 100 includes an intermediate structure 110 and may further include an outer tube 115. The mixing structure 100 shown in FIG. 2 includes an outer tube 115 and an intermediate structure 110.

The intermediate structure 110 is in the form of a tube having the same diameter as the first pipe 11 and the third pipe 13 and one side of the intermediate structure 110 is in communication with the downstream side end of the first pipe 11 , And the other side of the intermediate structure 110 can communicate with the upstream end of the third pipe 13. The intermediate structure 110 can communicate the first pipe 11 and the third pipe 13 so that the first fluid 1 can flow from the first pipe 11 to the third pipe 13.

A plurality of injection openings 113a may be formed in the intermediate structure 110 along the circumferential direction. Each of the plurality of ejection openings 113a may be formed in a narrow and long microchannel shape. The injection port 113a shown in FIG. 2B is a hole extending in a linear shape in the radial direction with respect to the circumferential surface of the intermediate structure 110, and is formed by subdividing the second fluid 2 to be mixed with the first fluid 1 The two fluids (2) are injected into the first fluid (1).

The outer tube 115 is provided to communicate with the other side (lower end portion) of the second pipe 12 and is provided outside the intermediate structure 110 to connect the second pipe 12 and the intermediate structure 110. The outer tube 115 has a cylindrical shape and a communicating hole communicating with the second pipe 12 at one side thereof and is formed to be larger than the diameter of the intermediate structure 110 and to surround the outer side of the intermediate structure 110. An annular space 114 may be formed between the outer cylinder 115 and the intermediate structure 110. The annular space 114 is a cylindrical space for distributing the second fluid 2 introduced from the second pipe 12 to the plurality of ejection openings 113a. However, the shape of the annular space 114 is not limited to a cylindrical shape.

The plurality of injection openings 113a allow the annular space 114 of the outer cylinder 115 to communicate with the interior of the intermediate structure 110. In addition, the plurality of jetting ports 113a induce a jet flow of the second fluid 2. 2a and 2b, the first fluid 1 flows from the first pipe 11 into the interior of the intermediate structure 110 and the second fluid 2 introduced from the second pipe 12 flows into the annular The divided fluid is divided into a plurality of injection ports 113a and the divided second fluid 2 is subdivided through the plurality of injection ports 113a to flow through the first fluid 1). The second fluid 2 is subdivided through a plurality of radially distributed injection orifices 113a and is injected into the first fluid 1 flowing inside the intermediate structure 110 and the high temperature (second fluid 2) The low-temperature flow (first fluid 1) is structurally alternately formed in the intermediate structure 110, thereby greatly increasing the contact area between the first fluid 1 and the second fluid 2 to improve the mixing efficiency .

FIG. 3A is a conceptual diagram showing a second embodiment in which a shape of a Y-shaped tube is sprayed in a linear flow form, and FIG. 3B is a sectional view taken along line III-III of FIG.

3, the second pipe 22 extends obliquely at an angle with respect to the first pipe 11, and the first pipe 11, the second pipe 22, the intermediate structure 110, The third pipe 13 may form a Y-shaped pipe. Other components are the same as or similar to the embodiment of FIG. 2, and a duplicate description will be omitted.

FIG. 4A is a conceptual view showing a third embodiment in which a shape of a T-shaped tube is sprayed in the form of a rotating current, and FIG. 4B is a sectional view taken along line IV-IV of FIG.

In the embodiment of FIG. 4, each of the plurality of injection openings 113b is different from the embodiment of FIG. 2 in that the injection openings 113b are formed to be inclined at a constant angle along the circumferential direction with respect to the radial direction of the intermediate structure 110. According to this configuration, the second fluid 2 is subdivided through the plurality of ejection openings 113b and forms a rotational flow at the same time. Each of the plurality of injection openings 113b may induce a flow of the second fluid 2 in a vortex shape to further increase the contact area between the first fluid 1 and the second fluid 2. [

Therefore, by applying the shape in which the second fluid 2 is injected in the form of a rotating current, uniform fluid mixing can be achieved at a shorter distance. Other components are the same as or similar to the embodiment of FIG. 2, and a duplicate description will be omitted.

5A is a conceptual view showing a fourth embodiment in which a shape in which a fluid of a Y-axis tube is injected in a linear flow shape is applied, and FIG. 5B is a V-V cross-sectional view of FIG.

In the embodiment of FIG. 5, the intermediate structure 110 is further provided with an expansion portion 112, which enlarges the size of the intermediate structure 110. The outer tube 115 may be formed using a part of the third pipe 13. The upstream end of the third pipe 13 may extend to surround the intermediate structure 110 and serve as the outer cylinder 115. [

More specifically, the third pipe 13 is larger in diameter than the first pipe 11, and the downstream end of the second pipe 12 is connected to be communicated with the upstream end of the third pipe 13 . The intermediate structure 110 includes a straight pipe portion 111 having one side connected to the first pipe 11 so as to communicate with the first pipe 11 and a second pipe portion 11 having a diameter gradually increasing from the straight pipe portion 111 to the upstream side end portion of the third pipe 13 And an extending tube portion 112. [ The upstream end of the third pipe 13 forms an annular space 114 which surrounds the straight pipe section 111 and the outside of the pipe tube section 112.

A plurality of injection openings 113a are formed in the straight pipe portion 111 and the expansion portion 112 of the intermediate structure 110. [ The plurality of injection openings 113a are formed in the straight pipe portion 111 and the pipe expanding portion 112 in a radial direction so that the annular space 114, the straight pipe portion 111, and the pipe expanding portion 112 communicate with each other.

The second fluid 2 flowing from the second pipe 12 rotates along the annular space 114 and is distributed to the plurality of ejection openings 113a and the divided second fluid 2 passes through the plurality of ejection openings 113a, And is injected into the first fluid 1 flowing through the straight pipe portion 111 of the intermediate structure 110 and the expanded portion 112. The third fluid 3 as the mixed fluid of the first and second fluids 1 and 2 mixed in the intermediate structure 110 gradually increases in flow area as it flows along the expanded portion 112, And the second fluid 2 injected through the injection port 113a of the second fluid 2 is mixed again.

With this configuration, the flow area of the expanded portion 112 gradually increases, and the low-temperature flow of the subdivided first fluid 1 and the high-temperature flow of the second fluid 2 alternate in the circumferential direction, It is possible to further enlarge the contact area of the contact surface. Therefore, it is possible to solve the stratification of heat and the like within a short period of time at a shorter distance from the junction of the fluids having different temperatures. Other components are the same as or similar to the embodiment of FIG. 2, and redundant description is omitted.

FIG. 6A is a conceptual view showing a fifth embodiment in which a shape in which a fluid of a Y-axis tube is injected in a linear flow form is applied, and FIG. 6B is a VI-VI sectional view of FIG. 6A.

6 is different from the embodiment of Fig. 2 in that the outer tube is not provided and the shape of the intermediate structure 120 is different.

More specifically, the intermediate structure 120 may be accommodated within at least one of the first pipe 11 and the third pipe 13. In the embodiment of FIG. 6A, the first and third pipes 11 and 13 are accommodated.

The intermediate structure 120 may be formed in a cylindrical shape having a smaller diameter than the first and third pipes 11 and 13 and a constant diameter. At this time, the front end portion and the rear end portion of the intermediate structure 120 may be formed in a spherical shape, a polygonal shape, a streamline shape, or the like to minimize the flow resistance. A plurality of jetting ports 123a may be formed in the middle structure 120 in a circumferential direction and spaced from each other in a narrow and long microchannel shape.

The second pipe 12 passes through at least one of the first pipe 11 and the third pipe 13 and communicates with the intermediate structure 120. An extension 12a extending from the second pipe 12 to the intermediate structure 120 is passed through at least one of the first pipe 11 and the second pipe 13 to form the intermediate structure 120, . A communication hole is formed at one side of the intermediate structure 120, and the extended portion 12a is connected to communicate with the communication hole.

According to this configuration, the second fluid 2 flows into the intermediate structure 120 from the second pipe 12 through the extended portion 12a. An annular space 114 surrounding the outer side of the intermediate structure 120 is formed in the first and third pipes 11 and 13 and the first fluid 1 flows in the annular space 114. The second fluid 2 is subdivided in the interior of the intermediate structure 120 through a plurality of injection ports 123a and is radiated to the outer first fluid 1. Therefore, the mixing efficiency of the first and second fluids (1, 2) can be improved by radiating the second fluid (2) to the central portion of the first fluid (1) while reducing the flow path resistance of the second fluid .

In FIGS. 2, 3, 5 and 6, the lines drawn horizontally inside the third pipe 13 indicate the linear flow of the first and second fluids 1 and 2, and the third pipe 13, The lines drawn diagonally inside indicate the rotational flow of the first and second fluids (1,2).

II. The structure in which the main flow is injected toward the branch flow

FIGS. 7 to 11 are conceptual diagrams showing a structure in which a main flow according to the pipe mixing apparatus of the present invention is injected toward a branch pipe flow.

Particularly, FIG. 7A is a conceptual view showing a sixth embodiment in which a shape in which a main fluid is injected in a linear flow form is applied, and FIG. 7B is a sectional view taken along the line VII-VII in FIG. 7A.

The mixing structure 200 includes an intermediate structure 210 disposed between the first pipe 11 and the third pipe 13 and having a plurality of injection ports 213a for subdividing the first fluid 1 , The first fluid 1 may be injected into the second fluid 2 through the plurality of injection ports 213a.

The second pipe 12 is disposed perpendicularly to the first pipe 11 and is brought into contact with the first pipe 11.

The intermediate structure 210 may be provided in a merging region where the first pipe 11 and the second pipe 12 meet with each other. One side of the intermediate structure 210 is connected to the downstream end of the first pipe 11 and opened to communicate with the first pipe 11 so that the first fluid 1 can be introduced into the intermediate structure 210 . The other side of the intermediate structure 210 may be formed into a conical shape in which the diameter gradually decreases toward the third pipe 13 from the rear end of the first pipe 11 and is inclined at an angle to narrow the area. However, since the shape may be formed in various shapes such as hemispherical shape in addition to the conical shape, it does not mean only the conical shape.

The upstream end of the third pipe (13) forms an annular space surrounding the intermediate structure (210). Since the annular space is formed by using a part of the third pipe 13, the outer cylinder 215 is not required. The downstream end of the second pipe 12 is communicatively connected to the annular space so that the second fluid 2 flows into the annular space. The annular space distributes the second fluid (2) to the injection port (213a) of the intermediate structure (210) to meet the first fluid (1).

The intermediate structure 210 has a plurality of injection ports 213a for injecting the first fluid 1 into the second fluid 2. [ The plurality of injection ports 213a are holes spaced along the circumferential direction and communicate the annular space with the interior of the intermediate structure 210. The jetting ports 213a may be formed in a narrow and long microchannel shape. The plurality of injection ports 213a extend linearly in the radial direction of the intermediate structure 210.

According to this configuration, the first fluid 1 flows into the intermediate structure 210 from the first pipe 11. The first fluid 1 is subdivided through the injection port 213a of the intermediate structure 210 and is radially ejected. The second fluid 2 introduced from the second pipe 12 is distributed to the injection port 213a of the intermediate structure 210 while rotating along the annular space and is discharged through the plurality of injection ports 213a, The first fluid 1 and the second fluid 2 are alternately brought into contact with each other along the circumferential direction, whereby the contact area between the two fluids can be greatly increased to effectively mix the fluid.

FIG. 8A is a conceptual view showing a seventh embodiment in which a shape in which a main fluid is injected in a linear flow form is applied, and FIG. 8B is a sectional view taken along line VIII-VIII in FIG. 8A.

In the embodiment of FIG. 8, the mixing structure 200 further comprises a cylindrical outer tube 215. The outer tube 215 is connected to the downstream end of the second tube 12 so that the second fluid 2 flows into the outer tube 215 from the second tube 12. The outer tube 215 may be formed in a cylindrical shape connecting the first pipe 11 and the third pipe 13. The outer tube 215 is larger in diameter than the first and third tubes 11 and 13 and the length of the outer tube 215 is longer than the diameter of the second tube 12. The outer cylinder 215 forms an annular space surrounding the intermediate structure 210. By forming the annular space, the flow rate of the second fluid 2 can be more uniformly distributed in the circumferential direction.

The intermediate structure 210 is composed of a straight pipe portion 211 having a constant diameter extending from the downstream end of the first pipe 11 to the inside of the outer cylinder 215 and a conical portion 212 having a gradually decreasing diameter. The end of the conical portion 212 can be received within the third pipe 13. A plurality of injection openings 213a are provided in the straight pipe portion 211 and the conical portion 212 of the intermediate structure 210. [ The plurality of injection ports 213a are formed in a linear shape in the radial direction of the straight pipe portion 211 and the conical portion 212.
