Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides mixing of fluid and granular material,
The present invention also relates to a novel fluid passage structure for efficiently bringing a fluid into contact with the surface of a structure.

BACKGROUND ART Conventionally, when mixing or reacting gases, liquids, granular materials, etc., it is well known to supply these fluids into a container filled with a honeycomb structure or granular filler.

However, the former method using a honeycomb structure has the disadvantage that it is troublesome to make the force-force structure.

In the latter method using granular fillers, although the structure of the device itself is not so complicated, the passage resistance of the fluid is large. The wavy bodies are superimposed so as to intersect, and at the same time, a partition plate is interposed between the wavy bodies to mutually block the fluid flowing through the fluid passages of each wavy body, and a branch body is interposed between the wavy bodies to merge and divide the fluid. We proposed a "fluid passage structure".

In this structure, in addition to branching bodies that merge and divide fluids, a partition plate is provided in the fluid passageway to cut off fluid from above and below, so fluid can partially pass through this partition plate. The upper and lower layers are separated without contacting each other.

Therefore, since the fluid is mainly treated in laminar flow, it is preferably used in applications requiring laminar flow treatment.

□ ′・ However, the flow resistance due to the contact between the partition plate ′ and the fluid is large, and the number of abnormal stagnation areas increases, so there is a problem in terms of mixing efficiency of the fluid, powder, etc.

The object of the present invention is to improve the above-mentioned deficiencies of the prior art, and to excavate and mix the fluid in the same manner by repeatedly dividing the fluid in the fluid passage and then overlapping the divided parts. 'The contact interface between fluids and the contact interface between the fluid and the surface of the structure is updated, and diffusion and dispersion between the fluids: mass transfer such as absorption, heat transfer, reaction, and reaction by the catalyst present between the fluid and the surface of the structure. The aim is to provide a new cicada formation passage structure that can effectively perform functions such as promotion.

In order to achieve the above object, the present invention has the following basic configuration.

That is, (a) a plurality of corrugated bodies are stacked in such a way that the fluid passages of adjacent corrugated bodies intersect with each other; The branch bodies are arranged in a forest at intervals in the intersecting direction, and (c) the fluid passages of the wavy body between the forest of branch bodies are completely opened, and the respective fluid passages are completely mutually connected. A fluid passage structure characterized by being in a conductive state.

The present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of the structure according to the present invention, in which corrugated bodies 1 and 1' are laminated, and branch bodies 2 are arranged at strategic points between the corrugated bodies 1 and 1'. It is set up.

The relationship between the wavy body 1 and the branch body 2 is such that the branch body 2 is fixed to the surface thereof as shown in FIGS. 2-1 and 2-2.

The branch body 2 preferably has a triangular shape as shown in FIG. 3-1.

Further, the branch body 2, the wavy lines 3 at the peaks, and the wavy lines 4 at the valleys of the wavy body are arranged so as to intersect at an angle θ.

The difference between the wavy bodies 1 and 1' is that when they are stacked, the wavy lines intersect with each other, as is clear from Figures 2-1 and 4-1.

This is the point where it becomes obvious.

The relationship between the wavy body 1' and the branched body 2 is shown in Figures 4-1 and 4-2.
As is clear from the figure, the relationship is almost the same as that between the wavy body 1 and the branched body 2.

The flow of fluid within this structure will be explained with reference to FIGS. 5-1 and 5-2.

5-1 and 5-2, the fluid A flowing into the opening 5 formed by the corrugated body 1.11 is connected to the branch body 2.
', A''.

Fluid A// flows into the upper left passage formed by the corrugated body 1 because the corrugated body 1' and the branch body 2 are close to each other or come into contact with each other and block the passage! It flows into the branch body 2''.

On the other hand, the fluid portion flowing in from the opening 5' is also divided into fluids B/ and B// in the branch body 2', and B' is divided into the fluids B/ and B// in the wavy body 1'.
The water flows into the lower flow path formed by the water and reaches the branch body 2''.

Fluids A// and B/ are respectively fluid A/// at the branch body 2''.
, A////, fluid Byt, B////, and further, fluids A''' and B''' are combined into the upper layer and the lower layer, and in the upper passage formed by the corrugated body 1, fluid A// // .

B10 is combined with the upper layer and the lower layer and flows through the lower passage formed by the corrugated body 1'.

In this way, the fluid that has flowed into the corrugated body is divided by the branching body, and the fluids are mixed together, dispersed left and right, up and down, and moved downstream while being mixed.

Even if the wavy lines 3 and 4 of the wavy body are extended as shown in Fig. 3-2, the flow of fluid and its effect will hardly change.

Furthermore, the wavy lines do not necessarily have to be continuous; even if they are partially interrupted, this may be more effective, especially in the case of turbulent flow.

Furthermore, it is clear from the explanation of the fluid flow that the spacing and arrangement of the branch bodies need not be regular as shown in FIGS. 2-1 and 4-1.

The angle θ between the wave starting line and the trough line and the branching body is preferably 15° to 80° in order to improve the mixing state.

Further, the intersection angle between the wavy lines 3 and 4 of the wavy body 1 and the wavy line 3°4 of the wavy body 1' can be set to various values depending on the allowable pressure loss and the required flow dispersion state, but in general, 3
It is often used in the range of 0° to 120°.

FIG. 6 is a sectional view of a device showing another embodiment of the invention, in which corrugated bodies 1 are stacked and branch bodies 2 and 2' are arranged between the corrugated bodies.

The positional relationship between the wavy body 1 and the branch bodies 2, 2' is shown in Figure 7-1.
As shown in FIG. 7-2, the wave output line 3, trough line 4, and branch body 2 are arranged so as to intersect at an angle θ.

The branch body 2 is arranged on the upper surface of the corrugated body, and the branch body 2' is arranged on the lower surface of the corrugated body.

Figures 8-1 and 8-2 show the flow of fluid inside this structure.
This will be explained using the figure.

In FIGS. 8-1 and 8-2, fluid A flowing into the upper opening 6 formed by the corrugated body is divided by the branching body 2 into fluids A' and A'', where A'' flows toward the lower left and A'' flows toward the lower left. ' flows to the right.

On the other hand, the fluid B flowing into the lower opening 6' is converted into fluid B' by the branch body 2a.

It is divided into B//, with B' flowing to the upper left and B// flowing to the right.

Fluids A' and B' overlap vertically and flow through the upper passage formed by the corrugated body 1 to reach the branch body 2'b, where they are divided into two fluids and at the same time further overlap with the fluid flowing in from the other passage. They meet, intermingle, disperse to the left, right, up and down, and move downstream.

The wavy lines of the wavy body do not necessarily have to be continuous and may be partially interrupted, which may be more effective especially in the case of turbulent flow.

Furthermore, it is clear from the description of the fluid flow that the spacing and arrangement of the branch bodies need not be regular as shown in FIG. 7-1.

The angle θ formed by the branch line 3 and trough line 4 of the wave and the branch body 2 is preferably 15° to 1200° in order to improve the mixing and dispersion state.

FIG. 9 is also a diagram showing another embodiment of the present invention, in which the corrugated body 1
are laminated, and branch bodies 2 and 2' are arranged between the wavy bodies.

The difference from the embodiment shown in FIG. 6 is that the angle θ between the wavy lines 3 and 4 of the wavy body and the dispersion body is 90° in FIG. 9 as shown in FIG. The difference is the relative position of 2'.

The flow condition is as shown in Figures 11-1 and 11-2.
This is similar to Figure-1 and Figure 8-2.

FIG. 12 also shows another embodiment of the present invention, and the difference from FIG. 6 is that in FIG. In addition, as shown in FIG. 13, the branch bodies 2, 2'
The difference is the relative position of

The flow inside this structure is also shown in Figure 14-1 and Figure 14-2.When one flow is divided into two by the branch body and flows horizontally and vertically, it overlaps vertically with other fluids. 1
This same operation is repeated to mix and disperse the flows.

FIG. 15 also shows another embodiment of the invention, in which the corrugated body 2.2'
The relative positions of and the flow inside the structure are shown in Fig. 16, Fig. 17-1, and Fig. 17-2, respectively.

The shape of the wavy body used in the present invention may be a triangular wave, a sine wave, a trapezoidal wave, or a modified wave thereof, and in short, any shape may be used as long as it causes a fluid flow in accordance with the gist of the present invention. For example, Figure 18-1,
As shown in Figure 8-2, if partition plates are installed in parallel on both sides of one flat plate 7, it can be used instead of the wavy bodies shown in Figures 6, 9, 12, and 15. Can be used.

In the case of metal materials, the corrugated body is formed by processing the thin plate or wire mesh by press molding, pultrusion molding, bending molding, etc.

In the case of plastic materials, their thin plates or nets can be processed by press molding, vacuum forming, or injection molding.

Also, in the case of ceramic materials, they are processed by press molding, extrusion molding, etc.

The wavy body and the branched body may be integrally molded, or they may be molded separately and then assembled by adhesion or welding.

In the case of integral molding, plastic materials can be easily processed by vacuum forming, injection molding, etc.

An example of implementing the detailed fluid passage structure into an actual device will be described.

When used as a catalyst carrier, an aluminum oxide film is formed on a part or the entire surface of the corrugated body or branched body, and then a catalyst metal is supported on this surface according to a known method.

When the surface material of the corrugated body or the branched body is aluminum, the aluminum oxide film treatment method is carried out by a method such as anodic oxidation.

In addition, in the case of metal materials other than aluminum, the surface is plated with aluminum and then coated with the above method, ceramic spraying, adhesive, etc.
Apply powdered aluminum oxide using paint, etc.

In addition, if one or both of the corrugated body and the branched body are formed with a mesh material such as a perforated plate or fabric, and the surface is treated with the above-mentioned oxide film, the surface area increases, the flow on the surface is renewed, and the turbulence of the surface flow is improved. The effect of this structure is synergistic with that of the present structure, making it possible to obtain an excellent catalyst carrier.

However, when using a mesh material such as a perforated plate or fabric, depending on the size of the openings, the amount of fluid leaking through the corrugated material or branched material may increase, as detailed in the structural example. No fluid flow is formed, and satisfactory functions and effects cannot be achieved.

Therefore, the mesh size of perforated plates, textiles, etc. is 0.5.
It is preferable that it is less than or equal to mi IJ.

A catalytic metal is supported on the ceramic surface and used to form a catalytic body.

Fluids containing organic and inorganic gases and oxidizing gases in this catalyst body,
Alternatively, when a reducing gas is passed through, these gases are renewed (repeated) on the fluid surface by the action of the corrugated plates and branching bodies, and the fluid comes into uniform contact with the catalyst layer.

It has been revealed that due to this effect, the catalyst layer becomes significantly smaller than the conventional granular catalyst body when the pressure loss of the fluid is the same.

Next, if two or more types of fluids, that is, liquid and liquid, liquid and gas, and gas and gas, are supplied to the structure of the present invention, the action of the corrugated body and the branched body, that is, the renewal of the fluid interface,
By repeating the superposition of the fluids that have undergone the interface renewal, contact between the fluids can be made evenly and closely, so mass transfer operations such as extraction, absorption, distillation, evaporation, gas cleaning, heat exchange, etc., and heat transfer operations can be performed. can be done efficiently.

In gas-liquid contact such as distillation, absorption, and evaporation, please refer to Section 5-1.
Figure, Figure 5-2, Figure 8-1, Figure 8-2, Figure 11-1
Figure, Figure 11-2, Figure 14-1, Figure 14-2, Figure 1
In addition to the cases where the fluid flows in one direction as shown in Figures 7-1 and 17-2, liquid and gas often come into contact with each other in countercurrent or crosscurrent flow.

At this time, the gas is
1, 14-2, 17-1, and 17-2, it is preferable that the fluid flows countercurrently or crosswise to the fluid flows shown in FIGS. 1, 14-2, 17-1, and 17-2.

The liquid flows while the surface of the structure bends, and the gas repeatedly renews and overlaps the interface, thereby effectively transferring mass to come into contact with the liquid.

In addition, the surface of either or both of the wavy body and the branched body may not only be surface treated to simply support the catalyst as described above, but also have a structure in which irregularities are actively imparted.

The surface irregularities not only increase the surface area of the structure surface, but also impart turbulence to the fluid in contact with the surface, thereby improving the mixing and contact effects.

It has been confirmed through experiments that the ratio a/L is preferably in the range of 0.05 to 0.2, where a is the height of the surface unevenness and L is the peak of the waves of the wavy body. There is.

In addition to the above-mentioned devices, the fluid passage structure of the present invention can be used in heat exchangers, water sprinkler beds, chemical reactors, general fluid mixers, and the like.

The fluid passage structure of the present invention has a simple structure in which only branch bodies are provided in the corrugated body, so the pressure loss of the fluid at the open part forming the fluid passage can be small, and it can prevent abnormal accumulation. There are few opportunities.

Therefore, the fluid passage structure of the present invention has good mixing efficiency of fluid and powder, and is suitable for mixing highly viscous fluids, for example.

In addition, since the fluid in the upper and lower layers contacts and intersects the upper and lower layer fluid passages, which do not pass through a partition member that blocks the fluid passages from above and below, turbulent flow occurs at the contact interface. Therefore, not only can it be effectively used for mixing where turbulence effects are expected, but also various operations such as mass transfer, heat transfer, and general mixing can be performed extremely effectively, making it possible to miniaturize the equipment. , energy saving, and manufacturing cost reduction.
