Description

gas dissolving device

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

[0002] In general, a solution refers to a liquid 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, in the process of purifying wastewater from livestock farms or for supplying gas 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 liquid using a dissolving device that utilizes the Venturi effect.

[0007] However, conventional dissolution devices have limitations in stably mixing and dissolving liquids and gases by simply utilizing the Venturi effect. Specifically, conventional dissolution devices have problems in that most of the gas dissipates as it rises to the surface, or it is difficult to break the gas into microbubbles or nanobubbles in the liquid 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 up gas into microbubbles or nanobubbles to enable stable dissolution in a liquid.

[0010] The present invention provides a gas dissolving device including a main body pipe having a first flow path through which a fluid moves, a gas flow body part connected to the main body pipe and having a gas flow space, a gas supply pipe arranged on the outside of the main body pipe and having a second flow path communicating with the gas flow space, and a guide part having a guide hole communicating the gas flow space and the first flow path, wherein at least one side of the guide hole protrudes into the gas flow space or the first flow path.

[0011] In addition, the gas flow body part includes a first body member having a first flow space and a second body member having a second flow space communicating with the first flow space, and the guide part can be arranged between the first body member and the second body member.

[0012] In addition, the gas flow body part may be arranged on the inside of the main body tube, and a first flow guide surface having a diameter that gradually decreases in the direction of movement of the fluid may be provided on the inner surface of the first body member, and a second flow guide surface having a diameter that gradually increases in the direction of movement of the fluid may be provided on the inner surface of the second body member.

[0013] Additionally, the minimum diameter of the second flow guide surface may be provided to be larger than the minimum diameter of the first flow guide surface.

[0014] In addition, the inner surface of the second body member may further include an auxiliary flow guide surface that is positioned at the rear end of the second flow guide surface based on the direction of movement of the fluid in the first flow path and whose diameter gradually decreases in the direction of movement of the fluid in the first flow path.

[0015] In addition, the gas flow body part is arranged on the outside of the main body tube, the main body tube includes a first main body tube and a second main body tube in the direction of movement of the fluid, and the guide part can be arranged between the first main body tube and the second main body tube.

[0016] In addition, the guide part includes a guide body having a central hole formed in the center, and the guide holes can be arranged in multiple radial directions centered on the central hole.

[0017] Additionally, the guide hole and the center hole may be connected to each other.

[0018] Additionally, the guide hole and the center hole may be spaced apart from each other.

[0019] Additionally, the guide hole may have a width that gradually increases as it moves away from the center hole.

[0020] Additionally, the above guide body may be provided in multiple numbers.

[0021] In addition, the guide bodies facing each other can have multiple guide holes arranged at the same position based on the direction of movement of the fluid.

[0022] In addition, the guide bodies facing each other may have multiple guide holes arranged at positions that are misaligned with respect to the direction of movement of the fluid.

[0023] A gas dissolving device according to the present invention comprises a gas flow space provided in a gas flow body portion connected to a main body tube to receive gas supplied from the outside, and at least one side of a guide portion is provided to protrude into the gas flow space or a first flow path of the main body tube. Then, when gas received in the gas flow space moves to the first flow path through a guide hole provided in the guide portion, the gas is broken into microbubbles in the guide hole to ensure stable dissolution in the fluid.

[0029] Figures 6 to 8 are cross-sectional views of a gas dissolving device according to another embodiment of the present invention.

[0030] 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.

[0031] Referring to FIGS. 1 to 4, a gas dissolving device according to one embodiment of the present invention may include a main body pipe (100), a gas flow body part (200), a gas supply pipe (300), and a guide part (400).

[0032] The above main body pipe (100) may be provided with a first flow path (110) that guides the movement of fluid in the direction in which the fluid is discharged after being introduced.

[0033] Here, the main body pipe (100) may be formed in the form of a pipe with both sides open so as to guide the fluid introduced through the first flow path (110) and the gas supplied from the gas supply pipe (300) to be described later in the discharge direction. For example, the main body pipe (100) may be formed in the form of a circular pipe with a first flow path (110) having a circular cross-section so that the fluid and gas move evenly through the first flow path (110), but the present invention is not limited thereto.

[0034] One side of the above main body pipe (100) can be connected to a pumping means (not shown) that supplies fluid at a set pressure.

[0035] The above gas flow body part (200) is connected to the main body pipe (100).

[0036] In this case, the gas flow body part (200) may be provided with a gas flow space (210) that receives gas supplied from a gas supply pipe (300) to be described later.

[0037] The above gas flow space (210) provides a space in which one side of the guide part (400) can be placed while receiving gas supplied from the gas supply pipe (300), thereby enabling gas to be delivered to the first flow path (110) of the main body pipe (100) through the guide part (400).

[0038] In one embodiment, the gas flow space (210) is formed in a ring-shaped structure, so that the gas supplied from the gas supply pipe (200) can flow in a ring shape inside the gas flow body (200).

[0039] Here, the gas flow body part (200) may include a first body part (201) and a second body part (202). The first body part (201) and the second body part (202) may be formed in a tube shape open on both sides, and a first flow space (201a) may be provided on the outer surface of the first body part (201), and a second flow space (202a) may be provided on the outer surface of the second body part (202). At this time, the first flow space (201a) and the second flow space (202a) may be arranged to be in communication with each other.

[0040] Here, the first body member (201) and the second body member (202) of the gas flow body part (200) can be connected to the inner surface of the main body tube (100) so as to be arranged in the first flow path (110).

[0041] In this case, the inner surface of the first body member (201) may be provided with a first flow guide surface (203a) whose diameter gradually decreases in the direction of movement of the fluid in the first flow path (110).

[0042] In addition, the inner surface of the second body member (202) may be provided with a second flow guide surface (204a) whose diameter gradually increases in the direction of movement of the fluid in the first flow path (110).

[0043] The first flow guide surface (203a) increases the flow rate of the fluid moving through the first flow path (110) while allowing the gas to be stably introduced into the first flow path (110) through the guide portion (400). In addition, the second flow guide surface (204a) reduces the flow rate of the fluid passing through the guide portion (400) while allowing the microbubbles or nanobubbles generated through the guide portion (400) to slowly move, thereby stably mixing with the fluid.

[0044] Referring to FIG. 6, the minimum diameter 'a' of the second flow guide surface (204a) is provided to be larger than the minimum diameter 'b' of the first flow guide surface (203a), so that when the fluid moving through the first flow path (110) passes through the guide part (400), a vacuum is induced near the inner side of the rear end of the second body member (202) that comes into contact with the guide part (400), thereby enabling the gas to be stably introduced into the first flow path (110) through the guide part (400).

[0045] Referring to FIG. 7, on the inner surface of the second body member (202), an auxiliary flow guide surface (204c) having a diameter that gradually decreases in the direction of movement of the fluid in the first flow path (110) may be provided at the rear end of the second flow guide surface (204a) based on the direction of movement of the fluid in the first flow path (110). When the fluid moving through the first flow path (110) passes through the guide portion (400), a vacuum is induced near the inner side of the rear end of the second body member (202) that comes into contact with the guide portion (400), thereby enabling the gas to stably flow into the first flow path (110) through the guide portion (400).

[0046] The above gas supply pipe (300) is arranged on the outside of the main body pipe (100) and delivers gas supplied from the outside to the gas flow space (210). A second flow path (310) communicating with the gas flow space (210) may be provided in the above gas supply pipe (300).

[0047] Here, the gas supply pipe (300) may be formed in the form of a pipe with both sides open to guide the movement of gas to the gas flow body (200) through the second flow path (310). For example, the gas supply pipe (300) is preferably formed in the form of a circular pipe provided with the second flow path (310), but the present invention is not limited thereto.

[0048] In addition, one side of the gas supply pipe (300) can be connected to a pumping means (not shown) that supplies gas at a set pressure.

[0049] The above guide part (400) may be provided with a guide hole (410) that connects the gas flow space (210) of the gas flow body part (200) and the first flow path (110) of the main body pipe (100). At this time, at least one side of the guide hole (410) may be arranged to protrude into the gas flow space (210) or the first flow path (110).

[0050] In one embodiment, one side of the guide hole (310) may be arranged to protrude into the gas flow space (210), and the other side of the guide hole (310) may be arranged to protrude into the first flow path (110).

[0051] Conventional gas dissolution devices have a path formed on the inner surface of the pipe for introducing and dissolving gas, which causes the introduced gas to dissolve with the fluid moving to the inner upper surface of the pipe, resulting in a problem in which overall dissolution does not occur in the fluid. To solve this problem, the present invention has the effect of increasing gas solubility by protruding the guide hole (410) that guides the movement of gas toward the inner side of the main body pipe (100).

[0052] In this way, the above guide part (400) is arranged between the first body part (201) and the second body part (202) of the gas flow body part (200), and guides the gas contained in the gas flow space (210) of the gas flow body part (200) through the guide hole (410) to move to the inside of the main body pipe (100), more specifically, to the first flow path (110).

[0053] Here, the guide part (400) may be provided with a guide body (400a) having a central hole (420) provided in the center. The guide body (400a) is illustrated as having a circular cross-section, but is not limited thereto and may be varied in various ways depending on the cross-section shape of the first flow path (110). Here, the guide body (400a) is preferably formed of a plate material, but is not limited thereto.

[0054] In one embodiment, the guide portion (400) may have a circular plate structure having the same shape as the circular tube, and may have a diameter smaller than the inner diameter of the main body tube (100) to facilitate insertion between the first body member (201) and the second body member (202).

[0055] The above guide holes (410) may be provided in multiple radial directions on the guide body (400a) centered on the central hole (420).

[0056] In this way, when a plurality of guide holes (410) are radially provided in the guide body (400a), when guiding the gas accommodated in the gas flow space (210) to move to the first flow path (110), the gas accommodated in the gas flow space (210) is moved to the first flow path (110) in an evenly distributed state, thereby stably mixing with the fluid.

[0057] The guide body (400a) of the above guide part (400) allows the fluid moving through the first flow path (110) of the main body pipe (100) to pass stably through the central hole (420).

[0058] In addition, the central hole (420) also serves to increase the flow rate of the fluid moving through the first flow path (110) and to draw the gas contained in the gas flow space (210) through the guide hole (410) into the inside of the main body tube (100).

[0059] In addition, the guide hole (410) guides the gas contained in the gas flow space (210) of the gas flow body part (200) to move to the first flow path (110) of the main body pipe (100), and breaks the gas into microbubbles to ensure stable dissolution in the fluid.

[0060] Here, the plurality of guide holes (410) may be provided to communicate with the central hole (420) so as to guide the gas guided from the gas flow space (210) to move to the central hole (420).

[0061] In addition, as shown in FIG. 5, it is obvious that in another embodiment of the guide portion (400), a plurality of guide holes (410) and the central hole (420) may be provided spaced apart from each other at a certain interval.

[0062] In addition, the guide hole (410) may be provided in a cross-sectional shape in which the width gradually narrows as it approaches the central hole (420). Through this, the gas in the gas flow space (210) can be stably guided to the first flow path (110) through the guide hole (410), and the gas flowing to the first flow path (110) through the guide hole (410) can be broken into microbubbles.

[0063] In addition, when the guide hole (410) and the central hole (420) are connected to each other, the inner edge portion of the guide body (400a) has a free end shape, so that when the fluid and the gas collide, micro-vibrations are generated, which not only shake off the micro-bubbles attached to the surface of the guide body (400a), but also prevent the micro-bubbles from coagulating with each other, and also generate bubbles and vortices in the fluid, so that the gas is stably dissolved in the fluid. In this way, in the structure where the inner edge portion of the guide body (400a) has a free end shape, it is possible to increase the generation of micro-bubbles through micro-vibrations and also increase the melting efficiency of the gas in the fluid.

[0064] At least one of the above guide bodies (400a) can be placed between the first body member (201) and the second body member (202) of the gas flow body part (200).

[0065] When the above guide bodies (400a) are arranged in multiple numbers between the first body member (201) and the second body member (202), the multiple guide bodies (400a) can be arranged sequentially in the direction of movement of the fluid. Here, when the guide bodies (400a) are provided in multiple numbers, the dissolution capacity of the fluid and gas can be increased, and while the generation rate of bubbles in the fluid is increased, the gas can be broken down into microbubbles more stably, thereby allowing the gas to be dissolved in the fluid more stably.

[0066] In addition, when the above guide bodies (400a) are arranged in multiple units, they can be arranged spaced apart from each other. In this case, an additional body member can be arranged between the first body member (201) and the second body member (202).

[0067] And, when the guide body (400a) of the above guide part (400) is arranged in multiple numbers, the guide bodies (400a) arranged to face each other can arrange the plurality of guide holes (410) to be aligned with each other or arranged to be misaligned with each other based on the direction of movement of the fluid.

[0068] As shown in Fig. 8, a gas dissolving device according to another embodiment may include a main body (100b), a gas flow body (200b), a gas supply pipe (300b), and a guide portion (400b). Here, the gas supply pipe (300b) and the guide portion (400b) have the same structure as the gas supply pipe (300) and the guide portion (400) of the previously described embodiment, and thus a detailed description thereof will be omitted. However, the guide portion (400b) may be arranged between the first main body pipe (101b) and the second main body pipe (102b) of the main body (100b).

[0069] Here, the main body (100b) may be provided with a first flow path (110b) that guides the movement of the fluid in the direction in which the fluid is introduced and then discharged.

[0070] Here, the main body pipe (100b) may be formed in the form of a tube with both sides open so as to guide the fluid introduced through the first flow path (110b) and the gas supplied from the gas supply pipe (200b) to be described later in the discharge direction. For example, the main body pipe (100b) may be formed in the form of a circular tube with a first flow path (110b) having a circular cross-section so that the fluid and gas move evenly through the first flow path (110b), but the present invention is not limited thereto.

[0071] One side of the above main body pipe (100b) can be connected to a pumping means (not shown) that supplies fluid at a set pressure.

[0072] The main body tube (100b) may include a first main body tube (101b) and a second main body tube (102b). The first main body tube (101b) and the second main body tube (102b) may be sequentially arranged in the direction of movement of the fluid moving through the first flow path (110b).

[0073] On the inner surface of the main body (100b), a first flow guide surface (not shown) whose diameter gradually decreases in the direction of movement of the fluid in the first flow path (110b) may be provided in at least a portion of the front of the guide portion (400b) based on the guide portion (400b).

[0074] In addition, on the inner surface of the main body (100b), a second flow guide surface (not shown) whose diameter gradually increases in the direction of movement of the fluid in the first flow path (110b) may be provided in at least a portion of the rear of the guide portion (400b) based on the guide portion (400b).

[0075] The above gas flow body part (200b) is connected to the main body pipe (100b).

[0076] The above gas flow body part (200)b) may have a gas flow space (210b) provided in the circumferential direction of the main body pipe (100b).

[0077] In this case, the gas flow body part (200b) may be provided with a gas flow space (210b) that receives gas supplied from a gas supply pipe (300b).

[0078] The above gas flow space (210b) provides a space in which one side of the guide part (300b) can be placed while receiving gas supplied from the gas supply pipe (300b), thereby enabling gas to be delivered to the first flow path (110b) of the main body pipe (100b) through the guide part (400b).

[0079] Here, the gas flow body part (200b) may include a first body member (201b) and a second body member (202b). A first flow space (201c) may be provided in the first body member (201b), and a second flow space (202c) may be provided in the second body member (202b). At this time, the first flow space (202b) and the second flow space (202c) may be arranged to be in communication with each other.

[0080] In addition, the first body member (201b) of the gas flow body part (200b) may be connected along the circumferential direction to the outer surface of the first body tube (101b) of the main body tube (100b), and the second body member (202b) may be connected along the circumferential direction to the outer surface of the second body tube (102b) of the main body tube (100b).

[0081] In this way, the gas dissolution device of one embodiment is provided with a gas flow space (210) for receiving gas supplied from the outside in the gas flow body part (200) connected to the main body pipe (100), and at least one side of the guide part (400) is provided to protrude into the gas flow space (210) or the first flow path (110) of the main body pipe (100). Then, when the gas received in the gas flow space (210) moves to the first flow path (110) through the guide hole (410) provided in the guide part (400), the gas is broken into microbubbles in the guide hole (410) to ensure stable dissolution in the fluid.

[0082] 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.
