Description

The present invention relates to a generation device and a generation method.

In recent years, metal-organic frameworks (MOFs) have been attracting attention as one type of substance adsorbent. Organometallic complexes are also called organometallic structures, metal-organic structures, and porous coordination polymers (PCP), and are porous structures that can be produced from metal salts and organic compounds as raw materials. It is the material. Organometallic complexes have a lattice structure with highly regular nanometer-order lattice spacing formed by metal ions and organic ligands, and have functions such as storage, separation, and catalytic reactions of substances. It has been known. Organometallic complexes have a much larger surface area than other conventionally known porous materials, such as activated carbon, which is a graphite-based carbon material, and zeolite, which is mainly composed of silicon and aluminum. It has a unique substance adsorption ability that allows the design of a chemical environment.

For example, solvothermal methods and autoclave methods have been studied as methods for producing organometallic complexes. The solvothermal method and the autoclave method are batch-type synthesis methods in which a plurality of liquid materials are heated to a predetermined temperature and pressure and reacted in a pressurized container. Using the solvothermal method or autoclave method, a liquid material containing a metal salt and a liquid material containing an organic compound are heated to a predetermined temperature and pressure and reacted in a pressurized container to generate an organometallic complex. can do. For example, Patent Document 1 discloses a method for synthesizing zinc-based metal organic frameworks (Zn-MOFs) by a solvothermal method.

As in the technology described in Patent Document 1, it is possible to produce organometallic complexes on a large scale by proceeding the reaction in a relatively large container using a batch synthesis method such as the solvothermal method. , productivity can be improved. However, if the batch-type synthesis method described in Patent Document 1 is performed in a container with a large reaction space for solution synthesis, the concentration of the liquid material supplied into the container may be uneven, and the temperature and pressure inside the container may become uneven. unevenness is likely to occur. As a result, it is thought that there is a possibility that variations in the size (particle diameter) of the produced organometallic complexes tend to occur. Such problems are thought to occur not only when producing organometallic complexes, but also generally when producing reaction products through reactions between liquid materials.

(Reaction product generation device)
Hereinafter, a reaction product generation apparatus 100 according to an embodiment of the present disclosure will be described. In the following, a case will be described in which an organometallic complex (Metal-Organic Framework (MOF)) is generated as a reaction product by reacting a metal salt and an organic compound using the reaction product generation apparatus 100. This will be explained using an example.

FIG. 1 is a front view showing a schematic configuration of a generation device 100 according to an embodiment of the present disclosure. As shown in FIG. 1, the generation device 100 includes a plurality of material supply sections 110, a plurality of pumps 120, a recovery section 130, and an air injection section 140.

The plurality of material supply units 110 supply a liquid material toward one reaction space. The material supply section 110 includes a first material supply section 110a and a second material supply section 110b. The first material supply section 110a supplies the first liquid material 152a toward the reaction space M1. The second material supply unit 110b supplies the second liquid material 152b toward the reaction space M1. In the generation device 100 according to the present embodiment, the first material supply section 110a includes a first nozzle 112a configured to inject a first liquid material 152a, and the second material supply section 110b includes a second nozzle 112a configured to inject a first liquid material 152a. A second nozzle 112b is configured to spray material 152b. In addition, in this embodiment, the reaction space M1 receives the first liquid material 152a supplied from the first nozzle 112a of the first material supply section 110a and the second liquid material 152a supplied from the second nozzle 112b of the second material supply section 110b. This space includes a merging point where the two liquid materials 152b meet, and includes the intersection between the central axis of the flow path in the first nozzle 112a and the central axis of the flow path in the second nozzle 112b, which will be described later. It is an area.

The plurality of pumps 120 include a first pump 120a and a second pump 120b. The first pump 120a is connected to the first liquid material storage section 150a via a first supply pipe 160a. The first pump 120a sends out the first liquid material 152a stored in the first liquid material storage section 150a to the first material supply section 110a. The second pump 120b is connected to the second liquid material storage section 150b via a second supply pipe 160b. The second pump 120b sends out the second liquid material 152b stored in the second liquid material storage section 150b to the second material supply section 110b. As the first pump 120a and the second pump 120b, non-pulsating (non-pulsating flow) pumps may be used. By using non-pulsating pumps as the first pump 120a and the second pump 120b, the first liquid material 152a and the second liquid material 152b can be supplied at a constant flow rate. , and the second liquid material 152b can react with each other in just the right amount. As the pulsationless pump, for example, a Mono pump may be used. Alternatively, as a non-pulsating pump, a pump with pulsating flow improved to a non-pulsating flow can also be used. Moreover, as the first pump 120a and the second pump 120b, it is also possible to use a pump with pulsation (pulsating flow), and for example, a plunger pump or a gear pump with pulsating flow can also be used.

The recovery unit 130 collects liquids generated by a reaction between the liquid materials (first liquid material 152a and second liquid material 152b) supplied from the respective material supply units 110 (first material supply unit 110a and second material supply unit 110b). The reaction product 190 is recovered.

The air injection section 140 blows off the reaction product 190 generated in the reaction space M1 toward the recovery section 130 by injecting air toward the reaction space M1. In the generation device 100 according to the present embodiment, the air injection unit 140 includes an air injection nozzle 142 configured to inject air vertically downward (ie, in the −Z direction). Further, as shown in FIG. 1, the reaction space M1 is located outside the injection opening 118a of the first nozzle 112a of the first material supply section 110a and the injection opening 118b of the second nozzle 112b of the second material supply section 110b. The air injection nozzle 142, which is the air injection unit 140, is located downstream of the air injection nozzle 142 in the air injection direction (-Z direction).

In the generation device 100 according to this embodiment, the first material supply section 110a, the second material supply section 110b, and the air injection section 140 are provided on the support member 170. The generation device 100 according to the present embodiment also includes a heating section 180 (see FIG. 3) and the like. The heating section 180 will be described later.

The structure of the material supply section 110 and the air injection section 140 of the generation device 100 will be described below with reference to FIGS. 2 to 4. 2, 3, and 4 are a perspective view of the support member 170, a front view viewed from the +Y direction, and a bottom view viewed from the −Z direction, respectively.

The support member 170 supports the first material supply section 110a, the second material supply section 110b, and the air injection section 140, and has a rectangular parallelepiped outer shape as shown in FIG. As shown in FIGS. 2, 3, and 4, the support member 170 has a side surface in the +X direction (YZ plane), a side surface in the -X direction (YZ plane), and an upper surface in the +Z direction (XY plane). Installation sections 172a, 172b, and 172c are provided for installing the first material supply section 110a, the second material supply section 110b, and the air injection section 140, respectively. The installation part 172a and the installation part 172b are provided so as to face each other in the X direction at the same height when viewed in the Z direction. The first material supply section 110a is arranged with respect to the installation section 172a such that the injection opening 118a of the first nozzle 112a faces in the -X direction. Further, the second material supply section 110b is arranged so that the injection opening 118b of the second nozzle 112b faces the +X direction with respect to the installation section 172b. Therefore, the first material supply section 110a and the second material supply section 110b are arranged to face each other in the X direction. More specifically, in the first material supply section 110a and the second material supply section 110b, the straight line connecting the center of the opening 118a (the center in the cross section perpendicular to the X direction) and the center of the opening 118b is It is arranged so that it is parallel to the direction. In addition, although the case where the straight line connecting the center of the opening 118a and the center of the opening 118b is arranged parallel to the X direction has been described as an example, the present invention is not limited to this. The central axis of the flow path of the supply section 110a (the axis perpendicular to the opening 118a) and the central axis of the flow path of the second material supply section 110b (the axis perpendicular to the opening 118a) are inclined with respect to the X direction. It may be placed in For example, the central axis of the first material supply section 110a and the central axis of the second material supply section 110b may be inclined by ±10° with respect to the X axis (axis extending in the X direction).

Further, a mixing space 174 is provided on the lower surface side of the support member 170 in the −Z direction. The mixing space 174 is a space where the first material 152a supplied from the first material supply section 110a and the second material 152b supplied from the second material supply section 110b react. The mixing space 174 is provided so as to open below the support member 170 (in the -Z direction). As shown in FIG. 3, the upper surface (+Z-direction surface) of the mixing space 174 has a substantially semicircular shape that is convex upward in cross-sectional view (cross-section perpendicular to the Y direction (XZ plane)). Therefore, the upper (+Z direction) inner surface of the mixing space 174 has a hemispherical surface that is convex upward. As shown in FIG. 4, the opening 174a of the mixing space 174 is circular.

FIG. 5 schematically shows the reaction that progresses inside the support member 170. As shown in FIG. 5, the first liquid material 152a sent out in the -X direction from the first material supply section 110a and the second liquid material 152b sent out in the +X direction from the second material supply section 110b are connected to the supporting member. The first liquid material 152a and the second liquid material 152b in the mixing space 174 of 170 collide in the reaction space M1 including a merging point where they meet. In this embodiment, the first liquid material 152a contains a metal salt, the second liquid material 152b contains an organic compound, and the collision between the first liquid material 152a and the second liquid material 152b causes the first liquid material to The metal salt in the second liquid material 152a reacts with the organic compound in the second liquid material 152b, and a substance that becomes the core of the organometallic complex is produced as a reaction product. In the generation device 100 according to the present embodiment, at this time, the air injection unit 140 injects air into the reaction space M1 within the mixing space 174 in the −Z direction. Therefore, the substance that forms the core of the organometallic complex generated by the collision between the first liquid material 152a and the second liquid material 152b is blown away in the −Z direction. The substance that forms the core of the organometallic complex is discharged from the opening 174a of the mixing space 174 to the outside of the support member 170 in the -Z direction. The discharged reaction product, which is the core substance of the organometallic complex, is recovered by the recovery section 130 provided in the -Z direction of the support member 170.

Hereinafter, the effects of the generation device 100 according to this embodiment will be explained.

Conventionally, various methods have been used to produce reaction products. For example, when a metal salt and an organic compound are reacted to produce an organometallic complex as a reaction product, a solvothermal method, an autoclave method, etc. have been used. Using a solvothermal method or an autoclave method, a batch-type synthesis method involves reacting a liquid material containing a metal salt with a liquid material containing an organic compound in a pressurized container heated to a predetermined temperature and pressure. Metal complexes can be produced. Since the solvothermal method and the autoclave method are batch processes, mass production is possible if the reaction is allowed to proceed in a relatively large space. However, at this time, since the mixing space in which the solution synthesis reaction is performed is large, unevenness in the concentration of the liquid material supplied into the container and unevenness in temperature and pressure within the container tend to occur. As a result, the size (particle diameter) of the produced organometallic complex tends to vary. Therefore, depending on the batch-type production method, it may be difficult to control the particle size.

In the generation device 100 according to this embodiment, the plurality of material supply units 110a and 110b supply liquid materials 152a and 152b toward one reaction space M1, and the air injection unit 140 supplies air toward the reaction space M1. Make it spray. As a result of extensive studies, the present inventors have determined that by injecting air from the air injection unit 140 into the reaction space M1 where the liquid material 152a and the liquid material 152b collide, a reaction product having a more uniform size can be generated. I was able to do that. When a reaction is carried out by a batch method such as a solvothermal method or an autoclave method, the substances that form the core of the organometallic complex, which is a reaction product generated by the collision of the liquid material 152a and the liquid material 152b, are , may further stick to each other and become larger. However, in the generation device 100 according to the present embodiment, the reaction products are Since it is possible to suppress adhesion between the two, a reaction product having a more uniform size can be obtained.

Furthermore, in the generation device 100 according to the present embodiment, the first pump 120a and the second pump 120b can continuously supply the first liquid material 152a and the second liquid material 152b, respectively, so that reaction generation Continuous production of objects is also possible. For example, in the above-mentioned solvothermal method and autoclave method, although it is possible to produce a relatively large amount of reaction products at one time, continuous production is not possible because they are batch methods. Due to the above-described configuration, the generation device 100 according to the present embodiment is capable of continuous generation while improving productivity compared to conventional methods. It is also possible to suppress variations in the size of the reaction products produced.

In the generation device 100 according to the present embodiment, the first pump 150a is configured such that the first nozzle 112a of the first material supply section 110a injects the first liquid material 152a at a first flow rate that is a constant flow rate. may be done. Similarly, the second pump 150b may be configured such that the second nozzle 112b of the second material supply section 110b injects the second liquid material 152b at a second flow rate that is a constant flow rate. The first flow rate and the second flow rate may be, for example, predetermined flow rates. At this time, the first liquid material 152a and the second liquid material 152b are supplied at a constant flow rate, so that they can react with each other in just the right amount. The first flow rate and the second flow rate are, for example, both 200 ml/5 min (40 ml per minute). In other embodiments, the flow rate may not be constant. For example, it may be configured to dynamically change the flow rate.

In this embodiment, the injection pressure at which the first liquid material 152a is injected from the first nozzle 112a and the injection pressure at which the second liquid material 152b is injected from the second nozzle 112b are both controlled by the air ejecting unit 140 The injection pressure is set to be higher than the injection pressure for injecting. This can prevent the first liquid material 152a and the second liquid material 152b from being blown away by the air jetted by the air jetting section 140 before they collide with each other and react. Note that the injection pressure at which the first liquid material 152a is injected and the injection pressure at which the second liquid material 152b is injected may be controlled by the first pump 150a and the second pump 152b, respectively.

In the generation device 100 according to the present embodiment, the injection opening 118a of the first nozzle 112a of the first material supply section 110a and the injection opening 118b of the second nozzle 112b of the second material supply section 110b are disposed between them. They are separated from each other by a distance of 0.05 mm or more and 1.0 mm or less (distance D1 shown in FIG. 6). Note that FIG. 6 is a schematic cross-sectional view for explaining the relationship between the air injection section 140, the first material supply section 110a, and the second material supply section 110b. The distance D1 is the distance between the injection opening 118a and the injection opening 118b on a straight line connecting the central axis of the flow path in the nozzle 112a and the central axis of the flow path in the nozzle 112b. That is, as shown in FIG. 6, the distance D1 is the distance between the center of the injection opening 118a and the center of the injection opening 118b. The injection opening 118a and the injection opening 118b are, for example, circular. Therefore, the center of the injection opening 118a is the center of the circle of the cross section perpendicular to the X direction of the injection opening 118a, and the center of the injection opening 118b is the center of the circle of the cross section of the injection opening 118b perpendicular to the X direction. It is central.

When the distance D1 between the injection opening 118a and the injection opening 118b is less than 0.05 mm, the liquid material 152a and/or the liquid material 152b to be injected or the liquid material generated by the reaction between the liquid material 152a and the liquid material 152b. The reaction product may scatter and adhere to the injection opening 118a and/or the injection opening 118b, causing clogging of the first nozzle 112a and/or the second nozzle 112b. By setting the distance between the injection opening 118a and the injection opening 118b to 0.05 mm or more, nozzles (first nozzle 112a and second nozzle 112b) caused by scattered liquid materials 152a, 152b, reaction products, etc. The occurrence of clogging can be suppressed. Further, by setting the distance between the first material supply section 110a and the second material supply section 110b to 1.0 mm or less, the first liquid material 152a and the second liquid material 152b can react more reliably. Therefore, the productivity of producing reaction products can be improved.

Furthermore, in the generation device 100 according to the present embodiment, the injection opening 148 of the air injection nozzle 142 of the air injection section 140 is connected to the injection opening 118a of the first nozzle 112a of the first material supply section 110a, and the injection opening 118a of the first nozzle 112a of the first material supply section 110a. The distance (distance D2 shown in FIG. 6) from the straight line (straight line L1 shown in FIG. 6) connecting the injection opening 118b of the second nozzle 112b of the supply part 110b is 0.1 mm or more and 10.0 mm or less. They may be separated.

In this embodiment, by merging the liquid materials 152 (the first liquid material 152a and the second liquid material 152b) in a relatively fine space, a reaction product (for example, an organometallic complex) is generated. By reducing the number of nuclei and blowing them away with an air jet, further crystal growth and mutual adhesion can be suppressed. This makes it possible to produce reaction products of relatively uniform size. Note that, for example, if the need to reduce the number of nuclei is relatively small, the space in which the liquid materials 152 join each other does not need to be a minute space.

In addition, in the generation device 100 according to the present embodiment, the air injection unit 140 injects the injection opening 118a of the first nozzle 112a of the first material supply unit 110a and the second nozzle 112b of the second material supply unit 110b. The air injection unit 140 is arranged in a direction (+Z direction) perpendicular to the straight line (straight line L1 shown in FIG. 6) connecting the opening 118b, and the injection direction of the air injection unit 140 is the −Z direction. Therefore, in FIG. 6, the angle θa between the injection direction of the injection opening 148 and the straight line L1 is 90°, but the arrangement of the air injection part 140 is not limited to this. The air injection unit 140, for example, directs air to a straight line L1 connecting the injection opening 118a of the first nozzle 112a of the first material supply unit 110a and the injection opening 118b of the second nozzle 112b of the second material supply unit 110b. The angle θa of the injection direction may be greater than or equal to 45° and less than or equal to 135°.

Furthermore, in the generation device 100 according to the present embodiment, the diameters of the injection opening 118a of the first nozzle 112a of the first material supply section 110a and the injection opening 118b of the second nozzle 112b of the second material supply section 110b are, for example, , 0.1 mm or more and 1.0 mm or less. Further, the discharge pressure of the first liquid material 152a and the discharge pressure of the second liquid material 152b of the first nozzle 112a of the first material supply section 110a and the second nozzle 112b of the second material supply section 110b are, for example, 0.05 MPa. The pressure may be 1.00 MPa or higher.

Note that the distances, arrangement angles, etc. between the structures described above are merely examples, and other sizes may be used. Further, it can be changed as appropriate depending on the liquid material used, the environment in which it is used, the particle size of the reaction product produced, etc. For example, the injection pressure of the air injection unit 140 may be changed depending on the target particle size of the reaction product or the target variation in particle size.

In the generation device 100 according to this embodiment, the heating section 180 may be further provided as described above. As shown in FIG. 3, the heating section 180 may include a heating wire coil, for example, a coil-shaped heating section 180a provided around the first material supply section 110a, and a second material supply section. 110b, and a coiled heating section 180c provided around the air injection section 140.

For example, the first liquid material 152a injected from the first nozzle 112a of the first material supply section 110a and the second liquid material 152b injected from the second nozzle 112b of the second material supply section 110b are each supplied to the heating section 180a. And after being heated by the heating part 180b, it may be injected toward the reaction space M1. Furthermore, the air injected from the air injection section 140 may be heated by the heating section 180c and then injected toward the reaction space M1.

As illustrated in FIG. 3, the heating section 180 may be provided individually for each of the first material supply section 110a, the second material supply section 110b, and the air injection section 140, but is not limited thereto. Alternatively, the heating section 180 may be provided for two or all of the air injection section 140, the first material supply section 110a, and the second material supply section 110b. The heating unit 180 may be provided, for example, to heat the entire support member 170, or may heat, for example, the first supply pipe 160a and the second supply pipe 160b before each fluid is supplied to the support member 170. It may be provided to do so. The heating unit 180 may be configured using, for example, a heating wire or the like. The degree to which the liquid material 152 injected by the material supply unit 110 and the air injected by the air injection unit 140 are heated may be appropriately set, for example, depending on the materials to be reacted, the production amount, etc.

The nozzles (first nozzle 112a and second nozzle 112b) used in the air injection section 140, the first material supply section 110a, and the second material supply section 110b are not particularly limited, and conventionally known nozzles can be used. can do. As the nozzles used in the air injection section 140, the first material supply section 110a, and the second material supply section 110b, for example, a straight nozzle or a conical nozzle can be used.

The injection port nozzle 142 of the air injection unit 140 is a nozzle in which the shape of the air to be injected (the shape in a cross section perpendicular to the injection direction (the shape in a cross section parallel to the XY plane in FIG. 1)) is a rectangle. Good too. Such a nozzle is also called a slit type air nozzle. Further, the injection port nozzle 142 of the air injection unit 140 may be a nozzle in which the shape of the air to be injected (the shape in a cross section parallel to the XY plane) is circular. At this time, the air injected becomes cylindrical or conical straight air. In any nozzle, the size of the injection port and the injection pressure can be appropriately set based on the reaction product to be generated, the reaction rate, and the like.

(Modified example)
A modification of the reaction product generation apparatus of this embodiment will be described with reference to FIGS. 7 to 9. The reaction product generation apparatus 100 described above has been described as an example in which it includes two material supply sections 110 (the first material supply section 110a and the second material supply section 110b), but the number of material supply sections 110 is It is not limited to this. For example, when producing a reaction product using three or more liquid materials, three or more material supply sections 110 may be provided.

FIG. 7 is an enlarged top view schematically showing the vicinity of the reaction space M1 of the material supply section 110A of the modified example. That is, FIG. 7 shows a top view of a modified material supply section 110A viewed from the +Z direction. As shown in FIG. 7, the material supply section 110A includes three material supply sections 110a1, 110a2, and 110a3. 110 A of material supply parts are used when making three types of liquid materials 152 react. As shown in FIG. 7, the material supply section 110a1, the material supply section 110a2, and the material supply section 110a3 of the material supply section 110A are arranged, for example, at an angle of 120 degrees with each other. Therefore, the material supply section 110a1, the material supply section 110a2, and the material supply section 110a3 are arranged at equal intervals when viewed in the circumferential direction of a circle centered around the reaction space M1. By distributing the material supply section 110a1, the material supply section 110a2, and the material supply section 110a3 equally in this way, in the instruction member 170 including the material supply section 110A, three types of liquid materials can be supplied to each other at the same time. They can be caused to collide and react under certain conditions.

In the case of reacting three types of liquid materials, for example, in the same configuration as the generation device 100 according to the present embodiment including the two material supply parts 110a and 110b described with reference to FIG. It is also conceivable that the synthesized solution is injected from the first nozzle 112a, and the remaining one solution is injected from the second nozzle 112b for reaction. However, in that case, before the solution obtained by synthesizing the two liquid materials and the remaining one solution collide, the solid product produced by the reaction between the two solutions in the first nozzle, A problem may occur in that the crystals grow inside the first nozzle 112a and become crystals, causing the solution in the first nozzle 112a to become suspended and cause clogging. On the other hand, by using three material supply sections 110a1, 110a2, and 110a3 when reacting three types of liquid materials, as in the material supply section 110A of the modified example, it is necessary to synthesize two types of solutions in advance. Therefore, the occurrence of clogging inside the material supply section 110 can be suppressed. Therefore, the productivity of reaction products using three types of solutions can be improved.

Similarly to the material supply section 110A shown in FIG. 7, even when four or more types of liquid materials are used for reaction, the angle between the material supply sections 110 may be adjusted depending on the number of material supply sections 110. For example, a plurality of material supply units 110 may be equally distributed so as to form an angle calculated by 360°/number of nozzles (number of material supply units 110).

FIG. 8 is a top view schematically showing another modification of the material supply section 110B when viewed from the +Z direction. The material supply unit 110B is used when reacting four types of liquid materials 152. As shown in FIG. 8, the material supply section 110B includes four material supply sections 110b1, 110b2, 110b3, and 110b4. For example, the supply section 110b3 and the material supply section 110b4 are equally spaced so as to form an angle of 90 degrees with each other.

FIG. 9 schematically shows a material supply section 110C of still another modification. The material supply unit 110C is used when reacting six types of liquid materials 152. As shown in FIG. 9, the material supply section 110C includes six material supply sections 110c1, 110c2, 110c3, 110c4, 110c5, and 110c6. The supply section 110c1, the material supply section 110c2, the material supply section 110c3, the material supply section 110c4, the material supply section 110c5, and the material supply section 110c6 are equally spaced so as to form an angle of 60 degrees with each other, for example.

As another modification, for example, when reacting five types of liquid materials 152, five material supply units 110 are arranged so as to form an angle of 72°, which is an angle calculated by 360°/number of nozzles (5). may be equally distributed.

Even when reacting using three or more types of liquid materials, the air injection unit 140 injects air in the -Z direction toward the reaction space M1, as in the case where two types of liquid materials are used. It becomes possible to control the particle size of the reaction product and improve productivity. When two types of liquid materials are used, as described above, the air injection section 140 in which the cross-sectional shape of the ejected air flow is rectangular or circular may be used. In addition, when three or more material supply units 110 are used, the air injection unit 140 has a circular cross-sectional shape (that is, the air injection unit 140 has a cylindrical (or conical) shape of the air to be injected). It is preferable to use Liquid is supplied to the reaction space M1 using the air injection unit 140 having a circular cross-sectional shape, for example, so that the center of the circle that is the cross-sectional shape of the air flow to be injected is near the center of the reaction space M1. By injecting air to the material 152, it is possible to inject air at a relatively uniform injection pressure to the liquid material 152 supplied from each material supply section 110. Therefore, the reaction between the liquid materials 152 can proceed relatively uniformly.

With reference to FIGS. 10 and 11, an example of a generation device that can accommodate a plurality of different numbers of material supply units 110 will be described. FIG. 10 is a schematic top view (a top view parallel to the XY plane) of a support member 170G of a generation device according to another embodiment of this case, and FIG. It is a sectional view (a sectional view parallel to the XZ plane) seen from the direction.

As shown in FIG. 10, the support member 170G includes six nozzle installation parts 172g1, 172g2, 172g3, 172g4, 172g5, and 172g6 (hereinafter, the six nozzle installation parts are also collectively referred to as the nozzle installation part 172g). ). The nozzles of the material supply sections 110g1, 110g2, 110g3, 110g4, 110g5, and 110g6 are arranged in the nozzle installation sections 172g1, 172g2, 172g3, 172g4, 172g5, and 172g6, respectively. The outer shape of the support member 170G is cylindrical. Therefore, as shown in FIG. 10, the outer shape of the support member 170G is circular in a top view, and as shown in FIG. 11, the outer shape of the support member 170G is rectangular (for example, rectangular) in a cross section parallel to the XZ plane. be.

In the support member 170G, material supply parts 110g1, 110g2, 110g3, 110g4, 110g5, and 110g6 are configured to be detachable. In the case shown in FIG. 10, six material supply sections 110g1, 110g2, 110g3, 110g4, 110g5, and 110g6 are arranged in all six nozzle installation sections 172g1, 172g2, 172g3, 172g4, 172g5, and 172g6, respectively. The reaction using six types of liquid materials 152 is allowed to proceed. In the support member 170G, the nozzle installation parts 172g1, 172g2, 172g3, 172g4, 172g5, and 172g6 have the same size and shape, and the material supply parts 110g1, 110g2, 110g3, 110g4, 110g5, and 110g6 also have the same size and shape. They are the same size and shape.

For example, in the case where the reaction proceeds with the two types of liquid materials 152 described with reference to FIG. and 172g4, two material supply sections 110g1 and 110g4 can be installed and used, respectively. At this time, it is preferable to close the unused nozzle installation parts 172g2, 172g3, 172g5, and 172g6 because it is possible to suppress the adhesion of splashing liquid material and generated reaction products.

In addition, in the case of causing a reaction using the three types of liquid materials 152 described with reference to FIG. By doing so, it can be used as a generation device that reacts three types of liquid materials and generates a reaction product. In this case as well, it is preferable to close the unused nozzle installation portions 172g2, 172g4, and 172g6.

As explained with reference to FIGS. 7 to 9, when three or more types of liquid materials are caused to collide and react, the number of nozzles 112 in the material supply section 110 increases. The support member 170 will be processed. Like the support member 170G shown in FIGS. 10 and 11, by making the nozzle installation part 172g the same size and shape and making the material supply part 110 the same size and shape, the material supply part 110 can be formed into a unit. Depending on the type of liquid material 152 to be reacted, the nozzle 112 of the material supply section 110 that is necessary can be inserted into the nozzle installation section 172g. can do. At this time, by making the entire outer shape cylindrical like the support member 170G, each nozzle installation portion 172g and the material Each nozzle 112 of the supply section 110g can be arranged symmetrically.

The support member 170G described with reference to FIGS. 10 and 11 has six nozzle installation parts 172g, so it is particularly preferable when two, three, and six types of liquid materials 152 are reacted. For example, as a modified example of It can be used when mixing and reacting liquid materials 152. The number of nozzle installation parts 172 is not limited to six or eight, and the nozzle installation parts 172 may be provided as appropriate for the indicating member 170 depending on the number of liquid materials that may be jetted at the same time. Of the nozzle installation sections 172 provided, the nozzles 112 of the material supply section 110 may be arranged in the nozzle installation section 172 according to the number of liquid materials to be reacted, and used to generate reaction products.
