Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for supplying one or more types of fluids, particularly two or more types of fluids, to a honeycomb structure in which unit tubes having arbitrary cross-sectional shapes are arranged adjacently. This type of honeycomb structure can be used in various devices such as heat exchangers, mixers, burners, filtration devices, evaporation devices, electrolytic diaphragms, battery diaphragms, and osmotic membranes.

With conventional devices, it has been extremely difficult to continuously supply several types of fluids to each unit tube of this type of honeycomb structure.

In particular, it has not been possible to distribute and supply two or more fluids to adjacent small unit pipes without mixing them with a simple device. The most common conventional method is a type called an orthogonal honeycomb, in which unit tubes are stacked at right angles to each other in each stage, but this honeycomb method allows two or more types of fluid to flow through the unit tubes in each stage. However, if you were to use it in a heat exchanger, for example, heat exchange would only take place through the partition walls between each stage.
The degree of effective utilization of honeycomb partition walls is low. Furthermore, it has been extremely difficult to alternately and freely distribute and supply two or more types of fluids.

The present invention solves these problems and provides a device for distributing and supplying one or more types of fluid to each other in a honeycomb structure in which unit tubes having arbitrary shapes such as triangular, square, hexagonal, etc. are arranged adjacently. This is what we intend to provide.

That is, the present invention has a structure in which fluid introduction pipes that are arranged adjacent to each other and partitioned by a partition plate are brought into close contact with the end openings of honeycomb unit pipes, and an inflow prevention film is placed on the contact plane of the unit pipes to close the unit pipe ports where the fluid is not injected. 1 is a fluid supply device characterized in that:

Some embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the fluid supply device of the present invention, and is a plan view of the surface in contact with a honeycomb. Further, FIG. 2 shows a plan view of a honeycomb corresponding to the device shown in FIG. 1, and FIG. 3 shows a perspective view of an embodiment of the feeding device shown in FIG. 1.

In the fluid supply device of the present invention, a plurality of fluid introduction pipes 2 partitioned by partition plates 5 are arranged adjacent to each other, and inflow prevention films 3 and inflow ports 4 are arranged alternately on the contact surface with the honeycomb. has been done. In use, this feeding device is brought into close contact with the honeycomb shown in FIG. At this time, each point of the supply device, K, L, M, N,
P, Q, R, S, T are each point of the honeycomb,
They overlap correspondingly to K′, L′, M′, N′, P′, Q′, R′, S′, and T′. When fluids A and B are injected into the fluid inlet pipes 2 every other time, the fluids flow through the inlet 4 into the end openings of the adjacent unit pipes 1 of the honeycomb. At this time, due to the arrangement of the inflow prevention membrane 3 and the inlet port 4, fluids A and B are alternately distributed to each unit tube 1 of the honeycomb as shown in FIG.

FIG. 4 shows another embodiment of the feeding device for the honeycomb shown in FIG. 2, and is a plan view of the contact surface of the honeycomb. Each point K, L, of the supply device in Fig. 4,
M, N, P, Q, R, S, T are the points K', L', M', N', P', Q', R', S', T' in Fig. 2 when used.
Fixed accordingly. Fluid introduction pipe 2 as shown in Fig. 4
If fluids A and B are injected into the system, the fluids will be distributed as shown in Figure 2 in exactly the same way as when using the system shown in Figure 1, but the system shown in Figure 4 will be distributed as shown in Figure 1. Therefore, there is an advantage that the inlet 4 becomes larger. In this way, various patterns can be considered for one honeycomb depending on the width and direction of the partition plate 5 of the fluid introduction pipe and the shape and arrangement of the inflow prevention film.

FIG. 5 shows another embodiment of the present invention, which corresponds to the lattice type honeycomb shown in FIG. Points K, L, M, N, P, Q, R, S, and T in Figure 5 are respectively K', L', M', N', P', Q', and Q' in Figure 6 when used.
It is held adjacent to R′, S′, and T′. If the fluids A and B are injected into the fluid introduction tube 2 every other unit as shown in FIG. 5, the two types of fluids A and B are distributed and supplied to every other unit tube of the honeycomb.

FIG. 7 is a plan view of the honeycomb joint surface of another embodiment of the feeding device for the lattice honeycomb shown in FIG. When the fluid is very easy to flow, such as gas, the inlet does not need to match the unit tubes of the honeycomb as long as the position is appropriate, and the inlet may be a hole-shaped inlet 4a shown in FIG. 7. The hole-shaped inlet 4a in FIG. 7 corresponds to the triangular inlet 4 in FIG.

Furthermore, FIG. 8 shows another embodiment of the lattice type honeycomb shown in FIG. K, L, M in Figure 8,
The points N, P, Q, R, S, and T correspond to the points K', L', M', N', P', Q', R', and
If the fluids A and B are held overlapped by S' and T' and fed from the fluid introduction pipe 2 as shown in FIG. 8, A and B will be distributed alternately as shown in FIG.

FIG. 9 shows another embodiment of the lattice-type honeycomb shown in FIG. 6, in which a hole-shaped inlet 4b is arranged at the position of the inlet 4 in FIG. 8.

FIG. 10 shows an embodiment of the feeding device of the present invention for a honeycomb having hexagonal unit tubes shown in FIG. 11. Points K, L, M, N, P in Figure 10,
Q, R, S, and T are respectively the points in Figure 11 when used.
It is installed so as to be in contact with K′, L′, M′, N′, P′, Q′, R′, S′, and T′. In this example, if fluids A, B, and C are passed through the fluid introduction pipe 2 as shown in Fig. 10, each of the fluids A, B, and C is regularly distributed and supplied to the unit pipe 1 of the honeycomb as shown in Fig. 11. be done. Even if the number of fluids increases to four or five, it can be distributed and supplied without confusion. Furthermore, for the honeycomb shown in FIG. 11, the shape and size of the inlet 4 can be changed by shifting the position of the partition plate 5 of the fluid introduction pipe. Note that it is also possible to easily create a countercurrent flow by flowing either fluid in the opposite direction from the other end opening of the unit tube of the honeycomb. Although the inflow prevention membrane 3 is attached to the introduction tube 2, it may be attached to the honeycomb unit tube 1 depending on the structure.

In the present invention, the term "fluid" includes gas, liquid, and any other known fluids, such as molten metals, salts, and other compounds. Furthermore, fluid powders such as pulverized coal can also be considered in the same way.

In addition, the materials of the fluid introduction pipe 2, inflow prevention membrane 3, partition plate 5, etc. of the fluid supply device of the present invention may vary depending on the purpose.
That is, it can be selected depending on the properties of the fluid, temperature, and other conditions.

The advantages of the present invention are as follows. First, the product of the present invention does not have a special shape like an orthogonal honeycomb, but can be applied to any ordinary honeycomb structure having various cross-sectional shapes such as triangular, quadrangular, and hexagonal. Second, it is possible to continuously distribute and supply one or more kinds of fluids, particularly two or more kinds of fluids, to any unit pipe without mixing them. Third, it has a simple structure, is easy to manufacture, is not restricted by materials, and is low in cost. Fourthly, a dramatic increase in the fluid contact area with the partition wall (membrane) per unit volume can be achieved. Due to these advantages, the product of the present invention not only improves the performance of devices using this type of honeycomb structure, but also opens up new applications for honeycomb that have not been previously considered. Some of them are shown below.

(1) Heat exchanger Fluids with different temperatures are used for fluids A and B, and a material with good heat conductivity is used for the honeycomb.

(2) Burner By using combustible gas as the A fluid and air, oxygen, etc. as the B fluid, and merging the two at the fluid outlet and igniting them, a burner with good mixing and complete combustion can be created without the risk of backfire.

(3) Filtration device If the honeycomb is made of a porous water-permeable material and a fluid containing fine particles is passed therethrough as fluid A, filtration is performed on each tube wall, and the filtered fluid flows out from the outlet of fluid B. When cleaning, conversely, the cleaning liquid can be flowed from the B fluid unit pipe and pressure applied. This filter has a wide filtration layer and is compact.

(4) Evaporation device If the evaporated material is placed in a porous honeycomb as fluid A, and hot air is passed through the fluid B side, the evaporated gas becomes B.
It moves to the side and evaporates efficiently in a short time.

(5) Heating/cooling reactor During chemical reactions, phenomena such as exothermic/endothermic events often occur, requiring heating, cooling, etc. Furthermore, there are many cases in which strict temperature control is required to maintain a stable reaction. By filling the unit tubes of this device with a catalyst as necessary, introducing reaction gas, etc., and passing heating and cooling fluids through the surrounding tubes, temperature can be adjusted efficiently and in a short time, making it easy to control the reaction. be able to. In addition, if there is a risk of fire, explosion, or leakage of dangerous components during the reaction, it is necessary to constantly keep digestive fluid, reaction stop solution, neutralizing, absorbing, and leakage prevention agents flowing into this adjacent pipe. It is also possible to prepare for safety in case of an emergency.

As described above, the fluid supply device of the present invention has high performance unimaginable with conventional honeycomb structures and opens up completely new uses, and has industrially useful value.
