Description

gas dissolving device

[0001] The present invention relates to a gas dissolving device for dissolving a gas in a fluid.

[0002] In general, a solution refers to a fluid in which a certain gas is dissolved.

[0003] Recently, solutions with high dissolved gas content have been manufactured, and in particular, the dissolved gas can exist as micro- or nano-bubbles of micro or nano size within the solution.

[0004] In this way, solutions with high dissolved gas content are used in various fields. For example, they are used in the process of purifying wastewater from livestock farms or to supply oxygen (O2) to fish in aquaculture farms.

[0005] In addition, solutions with high dissolved gas content are quickly absorbed into the body when consumed by animals or humans, have many effects such as activating metabolism and making them resistant to various pests and diseases, and are therefore widely used in water purifiers not only in livestock farms but also in general homes and companies.

[0006] These solutions are manufactured by mixing and dissolving gas in a fluid using a dissolving device that utilizes the Venturi effect.

[0007] However, conventional dissolution devices have limitations in stably mixing and dissolving fluids and gases by simply utilizing the Venturi effect. Specifically, conventional dissolution devices often dissipate gas as it rises to the surface, or they struggle to break the gas into microbubbles or nanobubbles in the fluid phase, hindering stable dissolution.

[0008] The related technology for such a melting device is presented in Korean Patent Publication No. 10-2023-0107094 (July 14, 2023).

[0009] The purpose of the present invention is to provide a gas dissolving device that breaks gas into nanobubbles and enables stable dissolution in a fluid.

[0010] The present invention provides a gas dissolution device comprising a gas dissolution tube having a flow path through which a fluid moves, and an impact disk portion having a plurality of impact blades arranged radially, at least one of which is arranged inside the gas dissolution tube, wherein the impact disk portion is connected to the inside of the gas dissolution tube and has a hollow connecting portion, and the plurality of impact blades are connected in a free end form to the inner surface of the connecting portion.

[0011] In addition, the gas dissolution tube is provided with an inlet through which fluid flows in and an outlet through which fluid flows out, and the diameter of the inlet may be provided to be larger than the diameter of the outlet.

[0012] In addition, when a plurality of collision disks are arranged in the above gas melting tube, the collision disks may be arranged at a constant interval from each other in the direction of movement of the fluid within the path.

[0013] In addition, the inner surface of the gas dissolution tube may be provided with a first flow guide surface whose diameter decreases as it goes in the direction of movement of the fluid in the passage, and a second flow guide surface whose diameter increases as it goes from the rear side of the first flow guide surface in the direction of movement of the fluid in the passage.

[0014] Additionally, the collision disk portion may be disposed between the first flow guide surface and the second flow guide surface.

[0015] Additionally, the collision disk section may be further arranged on the front side of the first flow guide surface and the rear side of the second flow guide surface.

[0016] In addition, the system may further include a fluid supply unit that is connected to the gas dissolution tube and supplies a fluid including gas to the gas dissolution tube in a swirling flow state.

[0017] In addition, the fluid supply unit may include a cylindrical fluid supply body having an internal space, a fluid inlet arranged tangentially to the outer surface of the fluid supply body and through which a fluid including gas flows in, and a fluid outlet provided in the fluid supply body and through which the fluid flowing into the fluid supply body is discharged.

[0018] In addition, the fluid supply body may further include a gas inlet port through which gas is introduced, and a gas supply unit connected to the gas inlet port and supplying gas into the interior of the fluid supply body.

[0019] In addition, the gas supply unit may include a gas supply line communicating with the gas inlet, and a gas supply valve disposed on the gas supply line and controlling the amount of gas supplied to the gas inlet.

[0020] The gas dissolving device according to the present invention moves by colliding with a plurality of collision blades radially arranged in a collision disk section when a fluid mixed with gas moves through a flow path of a gas dissolving tube. At this time, the plurality of collision blades are arranged in a free end form, so that when they collide with the fluid and gas, they break the gas into microbubbles, and also shake off the microbubbles attached to the surface of the collision blades and the surface of the collision disk section, thereby preventing the coagulation of the microbubbles and causing a vortex flow of the fluid, so that the gas can be stably dissolved in the fluid.

[0026] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Prior to this, it should be noted that the terms and words used in this specification and claims should not be construed as limited to their conventional or dictionary meanings. Based on the principle that the inventor can appropriately define the concepts of terms to best explain his or her invention, they should be interpreted in a way that conforms to the technical spirit of the present invention.

[0027] Referring to FIGS. 1 to 8, a gas dissolving device according to one embodiment of the present invention may include a gas dissolving tube (100) and a collision disk unit (200).

[0028] The above gas dissolution tube (100) may be provided with a flow path (110) that guides the movement of the fluid in the direction in which the fluid containing gas is introduced and then discharged.

[0029] Here, the gas dissolution tube (100) may be formed in the form of a tube with both sides open to guide the flow in the direction in which the fluid introduced through the flow path (110) is to be discharged. For example, the gas dissolution tube (100) may be formed in the form of a circular tube with a flow path (110) having a circular cross-section so that the fluid and gas are evenly moved through the flow path (110), but the present invention is not limited thereto.

[0030] The above gas dissolution tube (100) may be provided with an inlet (111) through which fluid flows in and an outlet (112) through which fluid flows out.

[0031] Referring to FIG. 2, the diameter of the outlet (112) may be provided to be smaller than the diameter of the inlet (111) so as to increase the pressure of the fluid flowing into the interior of the gas dissolution tube (100).

[0032] As shown in Fig. 3, the gas dissolution tube (100) may be provided with a fluid supply unit (120) that supplies a fluid mixed with gas in a swirling flow state.

[0033] The above fluid supply unit (120) can be connected to the gas dissolution tube (100) so as to communicate with the inlet (111).

[0034] Here, the fluid supply unit (120) may include a fluid supply body (121), a fluid inlet (122), and a fluid outlet (123).

[0035] The fluid supply body (121) may be formed in a cylindrical shape having an internal space. In one embodiment, the fluid supply body (121) may be formed of a pair of double-sided portions facing each other in a disc shape and a ring-shaped connecting portion connecting the double-sided portions. In this case, the pair of double-sided portions may be provided to have the same diameter.

[0036] The above fluid inlet (122) is connected to a pumping means (not shown) that supplies a fluid containing gas at a set pressure, thereby introducing the fluid into the internal space of the fluid supply body (121). Here, the fluid inlet (122) is arranged tangentially to the outer surface of the fluid supply body (121), so that the fluid introduced into the internal space of the fluid supply body (121) is in a swirling flow state.

[0037] The above fluid discharge port (123) is arranged at the center of one of the two sides of the fluid supply body (121) to discharge the fluid introduced into the fluid supply body (121) to the outside of the fluid supply body (121). Here, the fluid discharge port (123) can be connected to the inlet port (111) of the gas dissolution tube (100).

[0038] Additionally, the fluid supply body (121) may be provided with a gas inlet (124) through which gas is introduced. In addition, a gas supply unit (125) connected to the gas inlet (124) and supplying gas into the interior of the fluid supply body (121) may be arranged.

[0039] Here, the gas supply unit (125) may include a gas supply line (126) and a gas supply valve (127).

[0040] The above gas supply line (126) is a pipe member that connects a gas tank (not shown) storing gas and a fluid supply body (121). One longitudinal side of the gas supply line (126) is connected to a gas inlet (124), and the other longitudinal side of the gas supply line (126) can be connected to a gas tank.

[0041] The above gas supply valve (127) is placed on the gas supply line (126) so as to be connected to the gas supply line (126), and controls the amount of gas supplied into the internal space of the fluid supply body (121) through the gas inlet (124).

[0042] Here, the fluid outlet (123), gas inlet (124) and gas dissolution tube (100) of the fluid supply body (121) are arranged on the same center line, so that a stable flow can be ensured when the fluid and gas introduced into the interior of the fluid supply body (121) move to the gas dissolution tube (100) through the fluid outlet (123).

[0043] Referring to FIGS. 4 and 5, the inner surface of the gas dissolution tube (100) may be provided with a first flow guide surface (130) whose diameter becomes smaller as it moves in the direction of movement of the fluid in the flow path (110).

[0044] In addition, the inner surface of the gas dissolution tube (100) may be provided with a second flow guide surface (140) whose diameter increases from the rear side of the first flow guide surface (130) toward the direction of movement of the fluid within the flow path (110) based on the direction of movement of the fluid within the flow path (110).

[0045] Here, the inside of the gas dissolution tube (100) is configured with at least one first tube body (100a) and a second tube body (100b) in a detachable connection structure, and the first tube body (100a) and the second tube body (100b) can be sequentially arranged in the direction of movement of the fluid.

[0046] In addition, a first flow guide surface (130) may be arranged on the inner surface of the first pipe body (100a), and a second flow guide surface (140) may be arranged on the inner surface of the second pipe body (100b).

[0047] When the first pipe body (100a) and the second pipe body (100b) are arranged in multiples, the first pipe body (100a) and the second pipe body (100b) can be arranged sequentially and alternately in the direction of movement of the fluid.

[0048] This first flow guide surface (130) increases the flow rate of the fluid moving through the flow path (110), and causes the collision blade (210) to vibrate when the fluid and gas collide in the collision disk section (200) to be described later, thereby allowing microbubbles to be stably generated in the fluid.

[0049] In addition, the second flow guide surface (140) slows down the flow rate of the fluid moving through the path (110), and allows the microbubbles generated while passing through the collision disk section (200) to move slowly, thereby ensuring stable mixing with the fluid.

[0050] At least one of the above collision disk units (200) can be placed inside the gas melting tube (100).

[0051] Referring to FIG. 4, in one embodiment, when the first flow guide surface (130) and the second flow guide surface (140) are provided on the inner surface of the gas dissolution tube (100), the collision disk unit (200) may be arranged between the first flow guide surface (130) and the second flow guide surface (140) of the gas dissolution tube (100), more specifically, between the rear side of the first flow guide surface (130) and the front side of the second flow guide surface (140).

[0052] When the above collision disk units (200) are arranged in multiple numbers inside the gas dissolution tube (100), they can be arranged at regular intervals from each other inside the gas dissolution tube (100) based on the flow direction of the fluid moving through the path (110).

[0053]

[0054] *Referring to FIG. 5, in one embodiment, when the first flow guide surface (130) and the second flow guide surface (130) are provided on the inner surface of the gas dissolution tube (100), the collision disk unit (200) may be arranged between the first flow guide surface (130) and the second flow guide surface (140) of the gas dissolution tube (100), as well as on the front side of the first flow guide surface (130) and the rear side of the second flow guide surface (140).

[0055] Here, when the above collision disk units (200) are arranged in multiple numbers at regular intervals within the gas dissolution tube (100) based on the flow direction of the fluid moving through the path (110), the dissolution capacity of the fluid and the gas can be increased, and the rate of bubble generation in the fluid can be increased, while the gas can be broken down into microbubbles more stably, so that the dissolution of the gas in the fluid can be more stably achieved.

[0056] In this way, the above collision disk unit (200) finely breaks up the gas in the fluid moving through the flow path (110) of the gas dissolution tube (100) and creates micro bubbles in the fluid, thereby enabling the gas to be stably dissolved in the fluid.

[0057] Referring to FIGS. 6 and 7, the collision disk portion (200) is connected to the inner surface of the gas dissolution tube (100), and a connection portion (200a) having a hollow portion (200b) may be provided.

[0058] In addition, a plurality of collision wings (210) connected in a free end form on the inner surface of the above-mentioned connecting portion (200a) may be arranged. At this time, the plurality of collision wings (210) may be arranged radially with the hollow (200b) as the center.

[0059] In this way, the plurality of collision blades (210) can be provided with a cross-sectional shape that becomes narrower as they get closer to the hollow portion of the connecting portion (200a). This allows for a stable fluid flow to be maintained through the flow path (110) of the gas dissolution tube (100) while the gas passing through the gap between the adjacent collision blades (210) to be broken into fine bubbles.

[0060] In addition, since the plurality of collision wings (210) are each arranged in a free-end form, micro-vibrations are generated when the fluid and the gas collide, thereby removing micro-bubbles attached to the surface of the collision wing (210) and the surface of the connecting portion (200a) and preventing the micro-bubbles from coagulating with each other, and generating bubbles and vortices in the fluid, thereby allowing the gas to be stably dissolved in the fluid.

[0061] In this way, the above collision wings (210) are arranged in a structure having a free end shape on the inner surface of the connecting portion (200a), thereby increasing the generation of microbubbles through microvibrations and also increasing the solubility of gas in the fluid.

[0062] Referring to Fig. 8, the collision disk unit (201) of another embodiment is connected to the inner surface of the gas melting tube (100), and a connection unit (201b) having a central hole (201a) may be provided. In addition, the collision disk unit (201) may have a plurality of guide holes (202a) arranged radially based on the central hole (201a), and each guide hole (202a) and the central hole (201a) may be structured so that they are not connected to each other.

[0063] Here, the guide hole (202a) may be provided in a cross-sectional shape that becomes narrower as it approaches the central hole (201a). This allows the gas within the fluid flowing through the guide hole (202a) to be broken into microbubbles.

[0064] And, when the above collision disk units (200) are arranged in multiples, the collision disk units (200, 201) arranged to face each other can have multiple collision wings (210) arranged to be aligned with each other or arranged to be misaligned with each other based on the direction of movement of the fluid. When applying the collision disk unit (201) of another embodiment, multiple guide holes (202a) can be arranged to be aligned with each other or arranged to be misaligned with each other.

[0065] In this way, the gas dissolution device of one embodiment moves while colliding with a plurality of collision blades (210) arranged radially in the collision disk unit (200) as the fluid mixed with gas moves through the flow path (110) of the gas dissolution tube (100). At this time, the plurality of collision blades (210) are arranged in a free end form, so that when the fluid and the gas collide, the gas is broken into microbubbles, and the microbubbles attached to the surface of the collision blades (210) and the surface of the collision disk unit (200) are also shaken off, thereby preventing the coagulation of the microbubbles and causing a vortex flow of the fluid, so that the gas can be stably dissolved in the fluid.

[0066] While the present invention has been described with reference to the embodiments illustrated in the drawings, these are merely exemplary, and those skilled in the art will appreciate that various modifications and equivalent alternative embodiments are possible. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the appended claims.
