Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a composite unit for fluid treatment, a heat exchange member and a membrane separation member using the unit, and a method for transmitting high temperature through a heat exchanger plate incorporating these members. The present invention relates to a membrane separation device that transfers components from a fluid containing a desired separation component to a fluid for separating the components via a cross-flow heat exchanger that transfers heat from a fluid to a low-temperature fluid and a functional separation membrane.

Conventional technology As fluid processing equipment, heat exchangers that utilize the transfer of heat from high-temperature fluids to low-temperature fluids, and membrane separation equipment such as dialysis such as artificial dialysis and filtration applications such as ultrafiltration are widely used. There is. For example, heat exchangers are generally classified into parallel flow type, reverse flow type, and cross flow type, depending on the flow of high temperature fluid and low temperature fluid. Among these, cross flow type is constructed by stacking many plates. It is widely used because it requires relatively little installation space.

Problems to be Solved by the Invention In such a conventional heat exchanger in which plates are stacked one on top of the other, in order to maintain a constant gap between each plate,
Each plate is pre-embossed with a certain height of unevenness, which increases the overall height of the stacked plates, and also makes it impossible to narrow the gap between the plates even when the flow rate is low. There are disadvantages,
Moreover, due to the structure, it is difficult to reduce the floor space that the heat exchanger should have.

The present invention overcomes the drawbacks of the conventional plate-type fluid treatment device, has a simple structure, has excellent fluid treatment efficiency per unit volume, and can appropriately expand or contract the flow path space depending on the flow rate, etc. The object of the present invention is to provide a fluid processing composite unit, a heat exchange member, a heat exchanger, a membrane separation member, and a membrane separation device using the same.

Means for Solving the Problems The present inventor has conducted various studies in order to develop a fluid processing composite unit having the above-mentioned preferable characteristics, and a heat exchange member, membrane separation member, heat exchanger, and membrane separation device using the same. As a result of overlapping the rectangular thin plates, spacers are mainly arranged between the rectangular thin plates, and at least the rectangular thin plates are fused together or The sealed parts formed by joining should be disposed alternately and perpendicularly, and the spacers should be disposed so that at least the space between the rectangular thin plates forms a flow path from one end to the other. It was discovered that the object could be achieved by constructing it with a woven mesh board, and based on this knowledge, the present invention was created.

That is, the present invention stacks rectangular thin plates and spacers alternately, and fuses or joins the rectangular thin plates to each other along one set of parallel two sides of each rectangular thin plate surface or along the edge of another set. The formed sealing portions are arranged alternately and perpendicularly, and the spacers are arranged so that the space between the rectangular thin plates becomes a flow path from one end to the other, and the whole is constructed integrally. It consists of a fluid processing composite unit, a rectangular thin plate, an outermost outer plate, and a spacer arranged between the rectangular thin plates or between the rectangular thin plates and between the rectangular thin plate and the outer plate, and the surfaces of each rectangular thin plate are parallel to each other. The arrival parts formed by fusing or joining the rectangular thin plates and the rectangular thin plates and the outer plate are arranged so as to be alternately perpendicular to each other along the edges of one set of two sides or another set of edges, and A fluid treatment composite unit that is constructed as a whole by arranging spacers so that the space between the rectangular thin plates or between the rectangular thin plates or between the rectangular thin plates and the outer plate becomes a flow path from one end to the other end. It provides:

The rectangular thin plate used in the present invention is a square or rectangular thin plate made of metal, plastic, ceramics, composite materials thereof, etc., and a suitable one can be used depending on the field of use and purpose of use. It will be done. For example, for heat exchange, there are aluminum-deposited resin films, and for membrane separation, there are common dialysis membranes, lotus permeation membranes, ultrafiltration membranes, semipermeable membranes, dynamic membranes, etc. I can do it.

The outer plate used in the present invention is located on the outermost side and serves as a cover to protect the composite unit, and is usually the same shape as the rectangular thin plate but thicker than the rectangular thin plate, and is made of metal or plastic. There is.

The spacer used in the present invention is interposed between the rectangular thin plates or between the rectangular thin plates and between the rectangular thin plates and the outermost outer plate to ensure the required gap or spacing, and the space between the respective plates is from one end to the other. There is no particular restriction as long as it can be used as a flow path for the air, and examples of such items include nets and mesh plates, corrugated plates with triangular waves or circular arcs, and many circular pipes. Examples include a continuous tubular body made by connecting and integrating rectangular pipes (triangular pipes, rectangular pipes, etc.), and porous plates.

The material is usually metal or plastic, and may be elastic or flexible.

Particularly advantageously, it is formed of metal or synthetic resin filaments, such as a net plate formed by finely weaving or knitting the filaments, or press-molding the filaments into a net shape, and optionally forming a predetermined shape. A structure in which filaments are joined at intervals by spot welding or the like is used.

In addition, the rectangular thin plates or the rectangular thin plates and the outer plate are fused or joined along one set of parallel two sides of each rectangular thin plate surface or along the edges of another set to form a sealed part. The sealing portions are arranged so as to be alternately orthogonal to each other. For plastics, this fusion is done by heat sealing.
Bonding is performed, for example, via a sealing material such as an adhesive. /
One member may be provided on a rectangular thin plate or an outer plate, or may be provided on both ends of a spacer such as a mesh plate.

As a preferable example of the composite unit of the present invention, a large number of thin plates each formed by pasting strip-shaped edge plates along one set of two sides parallel to the upper surface of a rectangular thin plate are formed. The above-mentioned edge plates are stacked with alternating phases so that they are perpendicular to each other, and the upper surface of each edge plate is pasted and sealed on the lower surface of the corresponding upper thin plate, and a spacer is inserted between the thin plates. One example is one that is constructed in one piece.

The present invention also provides a heat exchange member made of the above-mentioned composite unit and in which the rectangular thin plate is heat conductive; a cross-flow type heat exchanger consisting of a membrane separation member comprising the composite unit and having a rectangular thin plate having membrane separation ability; It also includes membrane separation devices housed in casings that are opened orthogonally to each other.

Embodiment of the Invention An example of the heat exchanger of the present invention will be explained with reference to the drawings. FIG. 1 is a side sectional view, and FIG. 2 is a plan sectional view. A heat exchange member B in the form of a rectangular thick plate is housed in a casing A in which two sets of flow passages, a fluid inlet 1.3 and a fluid outlet 2.4, are arranged orthogonally.

As is clear from FIG. 1, the heat exchange member B consists of a thin plate 5 made of a metal foil such as aluminum foil cut into rectangles or a plastic film coated with aluminum evaporation, and a thin plate 5 made of a plastic filament or a plastic film. The fine mesh plates 6 formed by weaving metal wires vertically and horizontally are stacked alternately, and the periphery of the upper and lower thin plates 5.5 that sandwich the mesh plates 6 is edged, leaving one set of two parallel sides. Sealing is performed by joining plates 7 and 8,
The sealing edges are alternately orthogonal, and the sealing edges and open edges alternate at one end of the heat exchange member.

Figure 3 specifically shows the order in which this layering is carried out, that is, a band-like layer is placed on the top surface of the metal foil cut into a rectangle (square in the figure) along one set of two parallel sides. A thin plate 5 is placed above the thin plate 5a to which the edge plates 7a and 8a are attached.
b is its edge plate 7b.

8b is positioned with a different phase so as to be orthogonal to the edge plates 7a and 8a, and also below the thin plate 5a! = is edge plate 7c, 8
Thin plate 5c so that c is in the same direction as that of thin plate 5b.
These edge plates 7a, 8a, 7b,
8b, 7c, and 8c are respectively pasted on the lower surface of the upper thin plate, that is, 7a.

8a on the bottom surface of the thin plate 5b, and 7c and 8c on the thin plate 5a.

5c... On top are mesh plates 6a and 5b cut in advance to a size that fits between the opposing edge plates.

6c, or after pasting, insert and position them individually.

In this way, a large number of thin plates are stacked one on top of the other with mesh plates interposed between them, and the portion between the parallel edge plates of each thin plate becomes a flow path. In this case, in FIG.
... is shown as a square one, but each thin plate 5...
Of course, it is also possible to make it rectangular so that the area required for heat exchange differs depending on the fluid.

Functions and Effects of the Invention The fluid processing composite unit of the present invention has a simple structure and excellent fluid processing efficiency per unit volume, and can replace the interposed spacer with one of an appropriate size depending on the flow rate, etc. By using an elastic material to absorb an increase in fluid pressure due to an increase in flow rate by elongation due to elastic expansion and contraction of the spacer, a remarkable effect is achieved in that the flow path space can be increased or decreased as appropriate. For example, in the heat exchanger, the heat exchange member is composed of thin metal foil plates 5 and fine mesh plates 6, so the overall height can be made extremely low, and the heat exchanger Since the amount of heat transfer can be greatly increased, the heat transfer area of the entire device can be increased to 5 to 8 times that of conventional devices. In particular, if the mesh plate 6 is used as a spacer, the gap can be reduced to the conventional 115~]/8, and the fluid can flow freely between the meshes of the mesh plate, and the vertical and horizontal lines can be Further, since the upper and lower surfaces of the net plate 6 are horizontal planes as a whole, the thin plate 6...
