Description

Euro plate {FLUID CHANNEL PLATE}

The present disclosure relates to flow path plates, and more particularly to flow path plates of reactors.

A continuous flow reactor used in general chemical processes is a device for producing products by proceeding chemical reactions of fluids. The continuous flow reactor includes a passage through which fluids can move, and induces a chemical reaction by injecting fluids into a passage channel composed of such passages. In particular, the longer the residence time of the injected fluids in the passage channel, the more chemical reactions occur, and thus, the maximum number of products can be obtained. Therefore, the structural design of the passage considering the residence time of the fluids is very important. .

Conventional flow channels use a method of improving the mixing efficiency of mixed fluids and increasing the residence time by placing various obstacles in the flow path. A problem arises in that the flow rate decreases and the mixing efficiency rapidly decreases. In addition, the residence time of the fluids is not long compared to the price of the micro flow channel configured as one set, so product production is inefficient and economic loss occurs.

Therefore, there is a need for research on a method for manufacturing a flow channel having a longer residence time of a mixture and higher mixing efficiency than a conventional flow channel and a flow plate including the flow channel.

However, the present disclosure is not limited to the embodiments disclosed below and may be implemented in a variety of different forms. These embodiments are provided only to make this disclosure complete and to completely inform those skilled in the art of the scope of the disclosure, and the disclosure is only defined by the scope of the claims. . Therefore, the definition should be made based on the contents throughout this specification.

A mixture in this disclosure means a substance composed of one or more fluids. More specifically, a mixture of the present disclosure refers to a material composed of one or more fluids capable of undergoing a chemical reaction due to physical or chemical mixing.

The fluid of the present disclosure may be a material having flowable fluid properties. Specifically, a fluid may be a flowable substance comprising one or more different components or particles. For example, the fluid may be a flowable substance comprising solid particles such as a slurry. The aforementioned slurry is only an example of the fluid, and the fluid of the present disclosure is not limited to the slurry. Also, a fluid may refer to a fluid material having a phase such as liquid and gas. For example, the one or more fluids may include liquid-phase fluids and gaseous-phase fluids. The phases of each of the above-described fluids are only examples, and should not be interpreted as being limited to each phase of the fluids of the present disclosure due to the above-described examples.

The chemical reaction of the present disclosure is a chemical synthesis reaction that produces a product, and may be, for example, a digestion reaction, an oxidation reaction, halogenation, nitration, or a reaction using a toxic gas, but the present disclosure is not limited thereto. Accordingly, the chemical reaction of the mixture of the present disclosure may be a chemical synthesis reaction of fluids constituting the mixture. Also, the product of the present disclosure refers to a material produced through a chemical reaction of a mixture.

Additionally, the chemical reaction of the present disclosure may be a multi-step chemical reaction having two or more steps occurring sequentially. Specifically, in a chemical reaction having two or more successive steps, intermediate and final products are produced through sequential and successive steps. More specifically, in a chemical reaction having two or more steps, intermediate products are produced in each of the steps preceding the final step, and the final product produced in the final step may be produced through a chemical reaction of the intermediate product produced in the previous step. . For example, in a three-step chemical reaction, an intermediate product produced in step one is chemically reacted again in step two to produce another intermediate product. In addition, the final product produced in step 3, which is the final step, may be produced through a chemical reaction of other intermediate products produced in step 2. One step in the chemical reaction of the present disclosure may refer to a case in which two types of materials generate at least one new type of material through a chemical reaction.

A product of this disclosure refers to any material produced through a chemical reaction of a mixture. In addition, the product is not limited to a fluid, and may have a solid, liquid, or gas phase. In a chemical reaction of two or more stages, a product may be an end product, and may also be a reaction intermediate, intermediate or intermediate product. Intermediate products have strong energies in a short time and can refer to incomplete molecules. Accordingly, the intermediate product is not stable due to its high reactivity, and a chemical reaction with another substance or other molecule may quickly occur in order to be converted into a stable final product. That is, in the present disclosure, the final product is in a chemically stable state, and the intermediate product is in an unstable state. The following description of the product may be a description of all products unless separately described as a final product or an intermediate product.

The reactor of the present disclosure may be an apparatus for obtaining a product by causing a chemical reaction of the aforementioned mixture. Specifically, a chemical reaction may be induced through mixing of one or more fluids included in the mixture of the present disclosure. A reactor of the present disclosure may be any device capable of causing mixing of such a mixture to obtain a product. In addition, the reactor of the present disclosure may be a device capable of continuously flowing the mixture to cause uniform mixing of the mixture, and obtaining a product resulting from the mixing.

The reactor of the present disclosure may include one or more flow path plates including flow channel portions through which fluid may flow. Accordingly, when the mixture is injected into the reactor through the passage plate of the reactor, the mixture flows in the passage channel portion of the passage plate, and uniform mixing and chemical reaction of the mixture can occur. Thus, a product can be obtained from the mixture passing through the reactor.

For example, a reactor of the present disclosure may be a chemical reactor, a fluid reactor, a continuous reactor, a micro reactor, a reactor, a micro reactor, a continuous reactor, or a continuous flow reactor, and the like.

In the present disclosure, the residence time of the mixture may be the time required for the entire mixture to pass through the reactor when the mixture is injected into the reactor. Also, the retention time of the mixture may be the time required for the entire mixture to pass through the flow path plate.

For example, when 100 g of the mixture is injected into the reactor, the time taken for the entire 100 g of the mixture to pass through the reactor may be the residence time. Here, 100 g of the mixture passed through the reactor may contain the product as described above, and may have a different weight than 100 g. The weight of the mixture described above is only an example, and the weight of the mixture injected into the reactor or flow path plate of the present disclosure is limited and should not be construed due to the above example.

The flow path plate of the present disclosure is a component of a reactor including a flow path through which fluid can flow, and may have a shape of a plate or a plate defined in general mechanics. That is, one reactor may include one or more flow path plates. Specifically, the flow path plate of the present disclosure may include one or more flow channel portions through which fluid may flow. In addition, the passage channel portion of the present disclosure may be a set of passages, and may be a set configuration of minimum passages capable of obtaining a product from a mixture. Specifically, one example of the flow path plate and flow channel portion of the present disclosure is shown in FIG. 1 .

1 exemplarily illustrates a flow path plate according to an embodiment of the present disclosure.

As shown in FIG. 1 , the flow path plate 2000 of the present disclosure may include one or more flow channel units 1000 . In addition, the flow path plate 2000 may include a first inlet 2100 and a second inlet 2200 into which one or more types of emulsions may be injected. In addition, the flow path plate 2000 may include an outlet 2400 through which products or fluids passing through the flow channel portions 1000 may be discharged.

As shown in FIG. 1 , the flow channel unit 1000 of the present disclosure may include a first main flow path 2310 that is a passage through which fluid flows into the flow channel unit 1000 . In addition, the flow channel unit 1000 may include a second main flow path 2320 that is a passage through which fluid passing through the flow channel unit 1000 can be discharged.

As shown in FIG. 1, at least two of one or more flow channel parts 1000, one or more inlets 2100 and 2200, or one or more outlets 2400 included in a flow path plate 2000 of the present disclosure. may be integrally connected to each other. Specifically, the first main flow path 2310 of the present disclosure may be connected to inlets or may be connected to a second main flow path of another flow channel unit. Also, the second main flow path may be connected to the outlet 2400 .

Referring to FIG. 2, the flow path of the mixture is described. The first fluid injected into the first inlet 2100 and the second fluid injected into the second inlet 2200 of FIG. 1 form a first main flow path 2310. It is possible to move to one flow channel unit 1000 through . Here, the first fluid and the second fluid are mixed in the first main flow path 2310 to form a mixture, and a product may be generated by a part of the mixture. At least a portion of the mixture or at least one of the products passing through one flow channel unit 1000 may be transferred to the first main flow path of another flow channel unit through the second main channel 2320 . At least a portion of the mixture may be a mixture in which no final chemical reaction has occurred. At least a portion of the mixture or at least one of the products passing through all the passage channel portions 1000 included in the passage plate 2000 may be discharged through the outlet 2400 .

1 is only an example of a flow path plate, and due to FIG. 1, one or more flow channel portions, inlets, outlets, or main flow channels included in the flow path plate of the present disclosure should not be construed as being limited as shown in FIG. something to do.

One or more flow path plates included in the reactor of the present disclosure may be connected to each other. Specifically, an outlet of a flow path plate may be connected to an outlet of another flow path plate.

For example, when the reactor of the present disclosure includes three flow path plates, at least a portion of the mixture or at least one of the products passing through the outlet of the first flow path plate may be directly injected into the inlet of the second flow path plate. In addition, at least a portion of the mixture or at least one of the products passing through the outlet of the second flow path plate may be directly injected into the inlet of the third flow path plate. Thus, the product of the mixture can be successively passed through the three flow path plates and finally obtained through the outlet of the third flow path plate.

The number of flow path plates described above is only an example, and flow path plates that may be included in the reactor of the present disclosure should not be construed as being limited due to the above example.

The number of channels of the present disclosure may be the maximum number of flow channel units that may be included in one flow plate. That is, the flow path plate of the present disclosure may include a flow channel portion having a preset number of channels. Accordingly, the number of channels may be set based on at least one of the size of the passage unit unit or the size of the passage plate.

Also, the number of channels may be set based on the residence time of the mixture to produce the product. Specifically, the number of channels may be set based on the maximum residence time for obtaining the maximum amount of product from the mixture. That is, the number of channels of the present disclosure may be set based on at least one of a residence time, a size of a passage unit unit, or a size of a passage plate. Preferably, the number of channels of the present disclosure may be set based on at least one of a maximum residence time, a size of a passage unit unit, or a size of a passage plate.

Residence time in this disclosure may be the length of time a mixture must reside in a reactor to obtain a predetermined minimum amount of product from the mixture. In addition, the maximum residence time of the present disclosure may be the chemical reaction time of the mixture to obtain the maximum product from the mixture, the time for the entire mixture to pass through one flow channel, the time to pass through one flow plate, or one It may be one of the times it passes through the reactor.

For example, if a residence time of 10 hours is required to obtain the theoretically calculated maximum amount of product from the mixture, the passage channels required for each of the passage plates included in one reactor are based on the residence time of 10 hours. A negative number of channels may be calculated.

The foregoing time is only an example, and the sojourn time of the present disclosure should not be construed as being limited due to the foregoing time.

Preset in the present disclosure may mean calculated or determined in the step of designing a plate. In addition, the size of the present disclosure may be a geometric dimension representing the degree of occupancy of space, and may be, for example, volume, cross-sectional area size, or area. More specifically, the size of the present disclosure may be a dimension representing the amount occupied with respect to the total volume of the reactor or the amount occupied with respect to the total area of the flow path plate.

As described above, since the passage channel part is configured to generate a product by inducing a chemical reaction of the mixture, as a large number of passage channel parts are connected, the chemical reaction of the mixture is induced several times, so that maximum products can be obtained from the mixture. . Therefore, in order to obtain the maximum product for the mixture, the flow path plate of the present disclosure may include a maximum number of flow channel portions.

For example, the number of channels may be calculated as 100 for a flow path plate having a cross-sectional area of 100 cm 2 . Here, when 100 g of the first mixture passes through 100 flow channel portions, a much larger amount of product can be obtained than when 100 g of the first mixture passes through only two flow channel portions.

The size of the aforementioned passage plate, the amount of the mixture, and the number of channels are only examples, and the passage plate, mixture, and number of channels of the present disclosure should not be construed as being limited due to the above-described examples.

In addition, the flow channel unit of the present disclosure may include one or more flow unit units arranged according to a preset arrangement rule to increase a mixing rate while minimizing a space occupied by the flow plate. That is, in order to arrange as many flow channel parts as possible on one flow plate, one flow channel unit may be configured by arranging the flow unit units according to a predetermined arrangement rule.

The arrangement rule of the present disclosure may be a predetermined rule for arranging one or more passage unit parts with respect to one passage channel part. The arrangement rule of the present disclosure may be a method capable of maximally including the number of flow channel units and flow unit units in the flow path plate while inducing uniform mixing of the mixture.

Specifically, the arrangement rule of the present disclosure may be a rule for serially and alternately arranging passage unit sets including a preset standard number of passage unit units and a number exceeding the preset reference number of passage unit units. Here, arranging in series means connecting in a line, and may be connecting in a line parallel to or identical to the flow direction of the fluid.

The reference number of the present disclosure may be the number of flow unit units related to an arrangement rule, and may be set in advance based on at least one of the size of a flow path plate or the number of channels. That is, the reference number may be calculated based on at least one of the size of the flow plate and the number of channels. Also, the reference number may be set based on the above-mentioned stay time. That is, the reference number may be set based on at least one of the residence time, the size of the passage plate, and the number of channels. Preferably, the reference number of the present disclosure may be set based on at least one of the maximum residence time, the size of the flow path plate, or the number of channels.

The passage unit set of the present disclosure may be a set of passage unit parts having a number exceeding the predetermined reference number. Also, flow unit units included in the flow unit set of the present disclosure may be connected in parallel. Here, being connected in parallel means being arranged and connected horizontally, and may be connected in a line perpendicular to or different from the flow direction of the fluid.

For example, the reference number may be 1, and accordingly, the arrangement rule may be a rule for alternately arranging passage unit sets including one passage unit part and two passage unit parts connected in parallel in series. The above reference number is only an example, and the reference number or arrangement rule of the present disclosure should not be construed as being limited due to the above example.

Referring to FIG. 2, the passage unit unit and the passage unit set will be described in detail.

2 exemplarily illustrates one flow channel unit 1000 according to an embodiment of the present disclosure.

The flow channel unit 1000 shown in FIG. 2 includes one or more flow unit units 111, wherein the flow unit units 111 are arranged according to a predetermined arrangement rule. The arrangement rule of the passage unit parts 111 shown in FIG. 2 is an arrangement rule in which the reference number is 1. Accordingly, as shown in FIG. 2 , one passage unit unit 111 and the passage unit set 110 may be alternately arranged according to the arrangement rules. Also, as shown in FIG. 2 , the passage unit set 110 may include two passage unit parts 111 connected in parallel.

FIG. 2 is only examples of pay channel units and flow unit units, and should not be construed as limiting the flow unit set, flow unit unit, flow channel unit, standard number or arrangement rule of the present disclosure due to FIG. 2 .

The mixing ratio of the present disclosure may be the degree of uniform mixing of the fluids included in the mixture. Uniform mixing of the present disclosure means that the components included in each of the fluids are uniformly mixed with each other, and may be a mixture that can cause a chemical reaction of the fluids most similar to the theory. That is, uniform mixing may mean that fluids included in the mixture are uniformly mixed, and components included in each of the fluids may be uniformly distributed over the entire mixture. Uniform mixing can be influenced by the flow rate of the branched mixture, and uniform mixing can result in a uniform chemical reaction.

The passage unit unit of the present disclosure may have a passage configuration capable of dividing and flowing the mixture at least once. The passage unit unit may include two or more branch passages branching the mixture. The branch flow path of the flow unit unit of the present disclosure may be a flow path that separates and flows the mixture flowing within the flow unit unit.

In addition, the branching passages included in the passage unit unit may be connected to each other based on a preset joining angle for uniform mixing of the branched mixture. Specifically, the branch passages may be divided based on the impact surface and reconnected according to a joining angle. Here, the impact surface may be at least a part of a passage wall for reducing the flow velocity of the flowing mixture or obstructing the flow. That is, the mixture flowing in the flow passage unit may collide with the impact surface, and may be divided into each of the branch passages, flow, and then merge again. Here, the impact surface may preferably be configured in a concave shape.

Specifically, the passage unit unit and the branch passage of the present disclosure will be described with reference to FIGS. 3 and 4 .

3 illustratively illustrates a portion of a passage channel through which a mixture flows according to an embodiment of the present disclosure.

As shown in FIG. 3 , the mixture flowing in the flow direction A along the main flow path may flow in the direction of the arrow along the branch flow paths of the flow unit units. Specifically, the branch passages of the passage unit unit may be divided left and right while forming the impact surface 10 . Accordingly, the mixture first collides with the impact surface 10, and is divided into branched passages to flow. In addition, the divided and flowed mixture is mixed again at the junction 20 where the branch channels are connected, and the process of being divided and flowed again along the next branch channels and then mixed again is repeated. In this way, the mixture is uniformly mixed while repeating the process of being divided and flowed along the branch passages of the passage channel part based on the impact surface 10 and mixed again at the confluence point 20.

4 illustratively illustrates branch passages of a passage unit unit according to an embodiment of the present disclosure.

As indicated by a dotted line in FIG. 4 , a first branch passage 121 and a second branch passage 122 may be included in one passage unit 111 . The mixture may flow along dotted lines of each of the first branch passage 121 and the second branch passage 122 .

For example, 50g of the 100g mixture may flow through the first branch passage 121 and the remaining 50g may flow through the second branch passage 122 . Alternatively, 30g of the 100g mixture may flow through the first branch passage 121 and the remaining 70g may flow through the second branch passage 122 .

3 and 4 are only examples of flow unit units and branch passages, and flow unit units or branch passages of the present disclosure should not be construed as being limited due to FIGS. 3 and 4 .

The size of the passage unit unit of the present disclosure may be the overall size occupied with respect to the entire area of the passage plate. The size of the passage unit unit may be set based on the confluence angle, and the confluence angle may be set based on physical or chemical properties of each of the fluids.

Here, physical properties and chemical properties are inherent properties of a substance, physical properties are properties that can be measured without changing the essence of a material, and chemical properties appear when the essence of a material changes due to a chemical reaction. may be of a nature.

For example, physical properties may include melting point, viscosity, boiling point, density, and solubility, and chemical properties may include acidity, basicity, gas evolution, flammability, and explosiveness. The above-described physical properties and chemical properties are only examples, and the physical properties and chemical properties of the present disclosure should not be construed as being limited due to the above examples.

The joining angle of the present disclosure may be an angle at which branch flow passages are connected, and may be specifically an angle formed by internal center lines of each of the branch flow passages. Also, the joining angle may be set based on physical or chemical characteristics of each of the fluids.

Specifically, the joining angle may affect the flow rate of the mixture flowing through each of the branch flow passages. Accordingly, the joining angle may be set based on at least one of physical properties or chemical properties of each of the fluids included in the mixture.

For example, a first confluence angle when the physical property of the first mixture has low viscosity may be different from a second confluence angle of the second mixture having high viscosity. For another example, the third confluence angle for the third mixture including fluids subject to explosive reaction may be different from the fourth confluence angle for the fourth mixture including fluids without explosive reaction.

The above-described physical properties and chemical properties are only examples, and the physical properties or chemical properties of the present disclosure should not be construed as being limited due to the above examples.

In addition, the size of the passage unit unit of the present disclosure may be set based on the convergence angle. The size of the passage unit unit according to the present disclosure may be an area occupied by the passage unit unit within the passage channel part, and may be proportional to a horizontal length of the passage unit part. That is, as the convergence angle decreases, the horizontal length of the passage unit unit decreases, and thus the size of the passage unit unit may decrease.

Additionally, an area or shape in which the mixture collides with the aforementioned collision surface may be set based on the convergence angle. Here, the area of the collision surface on which the mixture collides may be the area of the wall of the passage that has an effect on obstructing the flow of the mixture or reducing the flow velocity. In addition, the shape of the impact surface may be a concave shape of the impact surface, and the degree of concaveness of the shape of the impact surface may increase as the convergence angle decreases.

The joining angle of the present disclosure will be described with reference to FIG. 5 as follows. 5 illustratively illustrates a confluence angle according to an embodiment of the present disclosure.

As shown in FIG. 5 , branch passages in the present disclosure may be connected at a confluence angle a′. Here, the area, shape, or horizontal length of the mixture colliding with the above-described collision surface may be set based on the convergence angle a'. Here, the area of the collision surface on which the mixture collides may be the area of the wall of the passage that has an effect on obstructing the flow of the mixture or reducing the flow velocity. Mixtures that are divided and flowed through the branching passages collide at a confluence angle (a') so that they can be mixed again.

When the confluence angle (a′) shown in FIG. 5 is reduced, the horizontal length of the passage unit portion may be reduced and the size of the passage unit portion may be reduced, and accordingly, the overall size of the passage unit portion may be reduced, as shown in FIG. 5 . When the merging angle a' becomes smaller, the area of the impact surface may be reduced or the concave degree of the shape may be increased.

The passage unit parts and the merging angle shown in FIG. 5 are only examples, and the passage unit parts or the merging angle of the present disclosure are limited and should not be construed due to the above-described examples and FIG. 5 .

The 3D molding device of the present disclosure may be a device capable of producing or molding a product using 3D printing technology. For example, the 3D molding machine of the present disclosure may be a 3D printer, but the 3D molding machine of the present disclosure is not limited to the 3D printer.

The 3D printer of the present disclosure is FFF (Fused Filament Fabrication, thermoplastic resin extrusion lamination method), SLA method (Stereo Lithography Apparatus, photocurable resin molding method), DLP method (Digital Light Processing), SLS method (Selective Laser Sintering, selective laser It may be a 3D printer implementing at least one of a sintering method), an inkjet method, or a polyjet method. Preferably, the 3D printer of the present disclosure may manufacture a product using an additive manufacturing method, and the flow channel portion of the present disclosure may be integrally manufactured through the additive manufacturing method of the 3D printer.

Hereinafter, a method of manufacturing a flow path plate according to an embodiment of the present disclosure will be described.

6 is a flowchart of a method of manufacturing a flow path plate included in a reactor according to another embodiment of the present disclosure.

A method of manufacturing a flow path plate of the present disclosure may include setting 710 the number of channels based on a size of the flow path plate. Specifically, the number of channels may be set based on at least one of the size of the passage unit unit or the size of the passage plate. Also, the number of channels may be set based on at least one of the aforementioned residence time, the size of the passage unit unit, or the size of the passage plate. Preferably, the number of channels may be set based on at least one of the aforementioned maximum residence time, the size of the passage unit unit, or the size of the passage plate.

Also, the reference number may be set based on at least one of the size of the flow plate or the number of channels. Here, an arrangement rule may be determined according to the set reference number, and a passage channel part including one or more passage unit parts arranged according to the determined arrangement rule may be determined. Also, the reference number may be set based on at least one of the residence time, the size of the flow path plate, or the number of channels. Preferably, the reference number may be set based on at least one of the maximum residence time, the size of the flow path plate, or the number of channels.

Accordingly, it is possible to configure one flow channel unit by arranging flow unit units according to an arrangement rule set based on a set reference number, and arrange the flow channel units as many as the above-mentioned number of channels for one flow path plate.

The method of manufacturing a flow path plate of the present disclosure may include manufacturing 720 a flow path plate including a flow channel portion having the number of channels using a 3D molding machine.

Specifically, as described above, the reference number may be set, and an arrangement rule of the passage unit unit may be set. Thereafter, the flow channel unit may be configured by arranging the flow unit units based on an arrangement rule, and such a flow channel portion may be manufactured using a 3D molding machine.

In addition, the 3D molding machine may include a 3D printer, and the channel portion may be integrally manufactured through an additive manufacturing method using the 3D molding machine.

For example, the number of channels may be calculated as 10 based on the size of the flow plate, which is 10 cm 2 . Accordingly, the number of channels is set to 10, and the reference number may be set to 1 based on at least one of the number of 10 channels or the size of the flow plate of 10 cm 2 . Accordingly, the arrangement rule may be determined as a rule for alternately arranging passage unit sets including one passage unit part and two passage unit parts connected in parallel.

Thereafter, through an additive manufacturing method using a 3D printer, it may be manufactured as an integrated flow path plate including 10 flow channel portions, which is the number of channels, in one flow path plate. That is, the flow path plate shown in FIG. 1 may be integrally manufactured.

Alternatively, each of the 10 flow channel parts included in one flow path plate may be integrally manufactured through an additive manufacturing method using a 3D printer. That is, the flow channel portion shown in FIG. 2 may be integrally manufactured.

In addition, each of the flow channel units integrally manufactured using a 3D printer may include one or more flow unit units arranged alternately in a flow unit set including two flow unit units connected in parallel with one flow unit unit. .

The size, reference number, arrangement rule, and number of channels of the passage plate of FIGS. 1 and 2 described above are only examples, and due to the above-described examples, the size, reference number, arrangement rule, number of channels, passage It should not be construed as limiting the plate, flow channel portion or flow unit portion.

As described above, the flow path plate of the present invention according to some embodiments of the present disclosure may be a set of flow channel parts including one or more flow unit units arranged in an arrangement rule. The flow path plate of the present disclosure is manufactured to increase the residence time of the mixture compared to plate configurations including existing flow channels, so that the amount of product that can be obtained from the mixture can be increased. That is, one reactor may include one or more flow path plates, wherein the flow path plate including the flow channel portion of the present disclosure may produce more products from the mixture during the same production time than the conventional flow path plate.

Therefore, the flow path plate according to some embodiments of the present disclosure can have a remarkable effect of being economical because the product production efficiency is better than before and the production cost can be reduced.

7 and 8 exemplarily illustrate branch passages of a passage unit unit according to an embodiment of the present disclosure.

According to one embodiment, the shape of the passage unit unit 600 in FIGS. 7 and 8 may have a streamlined shape including a water drop shape. The shape of the passage unit part 600 may include a streamlined shape with a pointed tip or a sharp tip. For example, the water drop shape may include a water drop shape. Hereinafter, for convenience of description, a water drop shape will be described as an example for the flow path unit unit 600 having a streamlined shape.

The water drop shape may have a sharp shape at the top and a gentle shape to a certain point at the bottom. The water drop shape of the present disclosure is formed at an angle close to a straight line from the front end to a specific position in the longitudinal direction of the flow unit unit, and may be formed at an angle close to a circle after the specific position. In another embodiment, the water drop shape has a shape in which the area is relatively rapidly widened from the front end in the longitudinal direction of the flow unit unit to a specific point in the lower part, and from the specific point to the distal end in the longitudinal direction of the channel unit unit. It may have a shape in which the area is relatively gently reduced.

The front end of the water drop shape may have, for example, a divergence angle of 30 degrees or more and less than 90 degrees, and divergent passages 670 , 680 , and 690 may be created by such a divergence angle. The divergence angle according to a preferred embodiment of the present disclosure is 45 degrees or more and less than 90 degrees, which improves the performance of the water drop-shaped passage unit part 660 as injection molding is easier in the case of the divergence angle range. While maintaining it, it is possible to advantageously reduce the manufacturing cost according to the injection of the product. That is, when the divergence angle is less than 45 degrees, since processing of sharp shapes becomes inconvenient and difficult, not only the cost of product molding may increase, but also contamination due to abrasion of the flow of reactants may occur. In addition, when the divergence angle is 90 degrees or less, there is an advantage in that the pressure drop can be reduced by eliminating the flow resistance of the fluid. Therefore, for the reasons described above, a preferred divergence angle will be 45 degrees or more and 90 degrees or less.

In one embodiment of the present disclosure, there may be flow passage units having various shapes and arrangements. The performance of the flow path in the state of liquid and gas mixture was compared for flow design models having flow unit units with various shapes and arrangements. As a result of comparison, the most optimal flow path performance was exhibited in the case of having a water drop shape but having the arrangement rule and the size of the channel portion according to one embodiment of the present disclosure. In the case of a fluid in a liquid-gas mixture, periodicity can be exhibited due to the inherent properties of each liquid and gas. For example, gases are compressible whereas liquids are incompressible substances. Therefore, when liquid and gas are injected together, unlike liquid, gas can be compressed and purified due to its inherent compressibility. In this situation, as the gas is continuously injected, the pressure of the compressed gas gradually increases, and as the pressure increases, this pressure can be used as a driving force to push the liquid.

The pressure of the gas instantaneously pushes the liquid and fills the inside of the passage, and then the pressure of the gas gradually decreases. Then, the phenomenon that the liquid occupies the space again can be repeated. In this way, when a mixed fluid of liquid and gas is drawn into the passage, a periodicity of fluctuations in speed and flow rate of the fluid is obtained due to the inherent properties of the gas and the liquid. In order to reduce the periodicity or fluctuation range of the periodicity, when the water drop-shaped passage unit parts are arranged according to a rule according to an embodiment of the present disclosure and the size of the channel part corresponding to the arrangement is formed, the flow changes according to a specific period. The periodicity was markedly reduced.

In addition, while the gas temporarily stays in a portion having a particularly large cross-sectional area, a phenomenon in which the volume of the gas instantaneously increases in the corresponding portion may occur. In the case of a phenomenon in which gas partially stays in a portion having a large cross-sectional area, it does not have a specific periodicity and may occur variably depending on the shape of the cross-sectional area of the passage. When the water drop-shaped passage unit parts 660 are arranged in a rule according to an embodiment of the present disclosure and the corresponding size of the channel part 1000 is formed, the gas temporarily stays in a specific part of the passage while the gas As the volume of the instantaneous increase, the phenomenon of non-periodic flow changes was significantly reduced.

Since the change in the cross section of the passage unit unit 660 of the present disclosure is not large in the longitudinal direction of the passage, the change in flow velocity is not increased. The channel unit unit 600 of the present disclosure has a streamlined shape as a whole and does not have an element that rapidly changes the flow.

The front end of the flow path unit part 660 of the present disclosure has an angular range of 45 degrees or more and less than 90 degrees, and due to the angular range of the front end, when air bubbles pass through, the gas is separated into sufficiently small bubbles, thereby gathering gases. can be drastically reduced.

According to one embodiment of the present disclosure, the water drop-shaped passage unit unit 600 includes a preset reference number of passage unit portions and a passage unit set in a number exceeding the preset reference number. It can be arranged according to the rule of alternating serially. The foregoing rules may have various embodiments, such as one flow unit and two flow unit units, one and three, two and three, and/or three and five.

According to one embodiment of the present disclosure, as shown in FIGS. 7 and 8 , the flow channel unit 1000 may have an external structure in which convex portions and concave portions are repeated. A first number of water drop-shaped passage unit parts are disposed at locations within the flow channel portion 1000 corresponding to the convex portion, and the water drop is disposed at locations within the flow channel portion 1000 corresponding to the concave portion. A second number of flow path unit parts of the shape are disposed, and wherein the first number may be greater than the second number by one.

As described above, the water drop-shaped passage unit unit is a rule for alternately arranging in series a passage unit set including a preset standard number of passage unit sections and a number of passage unit parts exceeding the preset reference number. can be arranged according to

In this regard, referring to FIG. 8 , the sum of area values A3 of passage cross sections at positions corresponding to the first position 630 is the sum of area values A3 of passage cross sections at positions corresponding to the second position 650 . can be the same as That is, A3 = a31 + a32 + a33 = A5 = a51 + a52 can be established.

In a further embodiment of the present disclosure, the third value A1 indicating the cross-sectional area of the third position 610 of the flow channel portion 1000 into which the fluid is injected may correspond to A3 and A5. That is, A1 = A3 = A5 can be established. In this way, as A1 = A3 = A5 is established, the phenomenon of stagnation of the incoming fluid can be easily eliminated. In particular, in the case of a fluid in which gas and liquid are mixed, fluid stagnation may be more rapidly reduced through the above-described structure.

In a further embodiment of the present disclosure, the flow channel cross-sectional area at the fourth position 640, which is a front position based on the first position 630 or the second position 650 of the flow channel unit 1000 The fourth sum value (A4 = a41 + a42) and the fifth sum value (A2 = a21 + a22) of the cross-sectional area of the passage at the fifth position 620, which is the rear position, are 1.5 compared to A1, A3, or A5. The flow channel unit 1000 may be configured to have a value not exceeding twice. In one embodiment, A2 and A4 may have values corresponding to each other. A2 and A4 each have a value less than 1.5 times that of A1. A2 and A4 each have a value less than 1.5 times that of A3. A2 and A4 each have a value less than 1.5 times that of A5.

In one embodiment, the calculation criterion of the cross-sectional area corresponding to the first to fifth positions is based on a direction perpendicular to a direction in which the fluid enters (ie, a flow direction of the fluid).

In one embodiment of the present disclosure, the sum of the cross-sectional areas of the N flow passages at the location where the N flow passages are formed within the flow channel portion 1000 and the N-1 flow passages within the flow channel portion 1000 The sum of the cross-sectional areas of the N−1 passages at the formed position and the sum of the cross-sectional areas of the N+1 passages in the passage channel portion may be equal to each other.

Referring to FIGS. 7 and 8 , the flow channel unit 1000 is located at position 670 where four flow channels 670a, 670b, 670c, and 670d are formed, and at position 680 where three flow channels 680a, 680b, and 680c are formed. Position 1 and the sum of cross-sectional areas of the passages at position 690 where the two passages 690a and 690b are formed may correspond to each other. That is, the sum of the cross-sectional areas of the four flow passages 670a, 670b, 670c, and 670d, the sum of the cross-sectional areas of the three flow passages 680a, 680b, and 680c, and the cross-sectional area of the two flow passages 690a and 690b The flow unit unit and the flow channel portion 1000 may be arranged and configured so that the sum values are equal to each other.

In a further embodiment of the present disclosure, it is considered that the sum of passage cross sections perpendicular to the flow direction of the fluid (reactant) does not vary greatly depending on the position, and the difference is approximately 1 to 1.5 times the cross section at the position where the reactant enters. It could be.

Alternatively, the sum of passage cross sections for each position of the flow channel unit 1000 may correspond to 1 to 1.5 times the average sum of passage cross sections. That is, the sum of passage cross-sectional areas perpendicular to the flow direction of the fluid may be within a range of 1 to 1.5 times the average sum of passage cross-sections.

As the passage channel portion 1000 is formed in consideration of the correspondence of areas as described above, the non-periodic and/or periodic phenomenon in which the fluid is stagnant when the fluid is introduced along with the characteristics of the water drop-shaped passage unit parts is eliminated. It can be.

Through the shape and arrangement of the flow channel unit 1000 illustrated in FIG. 9 and the internal streamlined flow unit units, the phenomenon of fluid stagnation when fluid is introduced can be eliminated, especially in the case of fluid containing gas. The effect of removing the phenomenon may be more excellent.
