Description

Dissolving device {DEVICE FOR DISSOLVING GAS INTO LIQUID}

The present invention relates to a dissolving apparatus configured to dissolve a gas in a liquid, and more particularly, to a dissolving apparatus using a venturi apparatus to dissolve a gas in a liquid.

In general, the dissolved solution means a liquid in which a predetermined gas is dissolved. The dissolved gas may exist in the solution in a very small size, for example, on a micro or nano scale, ie as micro bubbles or nano bubbles. Such a solution may have various new properties depending on the type and properties of the liquid as the solvent and the gas as the solute, and thus is used in various industrial fields such as agriculture, industry and medicine. For example, water is typically used as a liquid solvent in the solution, and air, oxygen, and carbon dioxide may be used as a gaseous solute.

The dissolving solution is usually prepared by a dissolving device, and the dissolving device is configured to mix and dissolve a gas in a liquid to produce a dissolving solution. Various devices can be applied for mixing and dissolving these gases, and among them, the venturi device capable of achieving high solubility is mainly applied to the dissolving device.

The duct 100 may include a flow path 100a configured to flow these liquids and solutions for transporting them. The flow path 100a is formed inside the duct 100 and may extend along the duct 100 . The duct 100 may include one end (or an upstream part) connected to the liquid supply source and the other end (or a downstream part) connected to a predetermined external device. For example, the other end (or downstream part) of the duct 100 may be connected to another device using the solution or a storage container for storing the solution. The duct 100 receives a liquid from an external source through the flow path 100a and supplies the liquid to the venturi device 1 connected in the middle of the duct 100, and the solution generated from the venturi device 1 again.

Accordingly, the dissolved solution generated and discharged from the venturi device 1 may flow through the second auxiliary duct 102 and the suction port 102a and be supplied to the duct 100, precisely the flow path 100a thereof. The supplied solution may flow along the flow path 100a of the duct 100 and be provided to a designated external device. That is, the liquid may bypass the flow path 100a of the duct 100 by the auxiliary ducts 101 and 102 and be converted into a solution in the venturi device 1 to be returned to the flow path 100a again.

Such duct and auxiliary ducts (100, 101, 102) may be a dedicated pipe for the dissolving device when the dissolving device is an independent device, that is, a separate device configured to form only a solution, and the dissolving device is a processing system using the generated solution may be part of such processing system piping.

Further, the venturi apparatus 1 may be connected to the duct 100 and configured to produce a solution, as described above. The venturi apparatus 1 may be configured to receive a liquid from the duct 100 to generate a dissolved solution, and to supply the generated solution to the duct 100 again.

Referring to FIGS. 3-6 in addition to FIGS. 1 and 2 referenced above, the venturi device 1 according to an embodiment of the present invention includes a housing 10, an injector unit 20, a valve member 30, It may include a stopper member 40 and a gas supply member 50 .

The housing 10 is a member provided in the shape of a rectangular box with an empty interior, and a flow pipe 11 in which at least one of a liquid and a gas dissolved liquid (ie, a solution) selectively flows in the housing 10 . and a bypass pipe 12 communicating with the flow pipe 11 to selectively bypass at least one of a liquid and a solution flowing through the flow pipe 11 .

The flow tube 11 may be a tube member provided to flow at least one of a liquid and a solution. This flow pipe 11 may be formed to extend in one direction. More specifically, the flow pipe 11 is provided at a position opposite to the supply end 11a and the supply end 11a, which are open to selectively supply liquid, and the discharge end 11b, which is open so that the solution can be discharged. ) and provided between the supply end 11a and the discharge end 11b, and may include a flow pipe passage portion 11c through which at least one of a liquid and a dissolved solution selectively flows. 2, the first auxiliary duct 101 is connected to such a supply end 11a, and the liquid from the duct 100 flows through the first auxiliary duct 101 and the supply end 11a. It may be supplied to the flow pipe 11 . In addition, the second auxiliary duct 102 is connected to the discharge end 11b, and the generated solution is discharged from the flow pipe 11, precisely the flow path 11c, to the discharge end 11b and the second auxiliary duct 102. It may be supplied to the duct 100 through the.

Meanwhile, as shown in FIGS. 4 and 5 , the diameter D1 of the supply end 11a may be substantially the same as the diameter D2 of the discharge end 11b. The injector unit 20 may be inserted through the supply end 11a. Meanwhile, in order to prevent the injector unit 20 inserted through the supply end 11a from being separated to the discharge end 11b, a step 11d may be provided in the flow tube passage portion 11c. Such a step 11d may be formed by protruding at least a portion of the inner surface of the flow tube portion 11c. At this time, the step 11d is in contact with the end of the injector unit 20 inserted through the supply end 11a to prevent the injector unit 20 from being separated to the discharge end 11b, as well as the injector unit 20 ) can also be prevented from being inserted through the discharge end (11b).

The bypass pipe 12 may be a pipe member provided to bypass the liquid flowing through the flow pipe 11 . In this case, the bypass pipe 12 may be connected to communicate with the flow pipe 11 through at least one connection part, and may be spaced apart from each other by a predetermined distance in a direction perpendicular to the extending direction of the flow pipe 11 .

Specifically, the bypass pipe 12 has an insertion end 12a that is open so that the valve member 30 is inserted, a closed end 12b that is closed while provided at a position opposite to the insertion end 12a, and an insertion end 12a ) and the closed end 12b, provided between the bypass tube portion 12c through which the liquid selectively flows may be included.

At this time, when the valve member 30 is completely inserted into the insertion end 12a, the inlet of the bypass pipe 12 is closed and the liquid in the flow path 11c of the flow pipe 11 flows into the flow path of the bypass pipe 12 . When the valve member 30 is separated from the insertion end 12a to such an extent that the valve member 30 fully inserted into the insertion end 12a is not completely separated from the insertion end 12a, it cannot be bypassed into the portion 12c. , while the inlet of the bypass pipe 12 is opened, at least a portion of the fluid of the flow path 11c may be diverted to the flow path 12c of the bypass pipe. Due to this detour, the flow rate of the liquid supplied to the injector unit 20 is changed, and the flow rate change causes a pressure change in the injector unit 20 . Accordingly, as the pressure of the gas injected from the plurality of injection members 23 of the injector unit 20 to be described later changes, the amount of gas injected also changes, and the amount of gas dissolved in the liquid in the injector unit 20 , that is, the dissolved solution gas concentration can be changed. That is, the bypass pipe 12 adjusts the gas pressure and the amount of gas supplied by adjusting the liquid amount and liquid pressure supplied to the injector unit 20 by the bypass of the fluid, and by this adjustment, the gas concentration in the dissolved solution (ie, solubility) can be controlled.

The injector unit 20 may mix a liquid and a gas to dissolve the gas in the liquid. To this end, the injector unit 20 may be detachably inserted into the flow pipe 11 of the housing 10 . Such an injector unit 20 will be described in more detail below with reference to the related drawings in addition to the previously referenced FIGS. 2 to 6 . 7 is a perspective view showing the injector unit of the venturi apparatus included in the dissolving apparatus of FIGS. 1 and 2 , and FIG. 8 is a cross-sectional view of the injector unit obtained along the line D-D of FIG. 7 .

7 and 8 , the injector unit 20 forms an exterior, a body 21 that is replaceably inserted into the flow pipe 11 , is provided inside the body 21 , and gas and liquid are mixed A venturi member 22 having a venturi flow path 221 that can be flowed and one end connected to the body 21, the other end connected to the venturi member 22, the circumferential direction of the venturi member 22 It may include a plurality of injection members 23 spaced apart along the arrangement.

The main body 21 may include an O-ring insertion part 211 in which at least a portion of the outer surface protrudes inwardly in the radial direction of the main body 21 . The O-ring insertion part 211 may extend along the circumferential direction of the body 21 and may be provided in plurality. In addition, the plurality of O-ring insertion parts 211 may be spaced apart from each other at predetermined intervals along the longitudinal direction of the body 21 . At this time, the O-ring member 213 may be inserted into the O-ring insertion part 211 , and airtightness between the flow pipe 11 of the housing 10 and the body 21 may be maintained by the O-ring member 213 . . Here, when the term for the direction is defined, the radially inner side of the main body 21 means a direction from the inner surface of the main body 21 toward the center of the main body 21, and the circumferential direction of the main body 21 is the main body ( 21) refers to a direction of rotation along the outer circumferential surface, and the longitudinal direction of the body 21 refers to the x-axis direction of FIG. 1 . At this time, the circumferential direction of the main body 21 may be any one of a clockwise direction and a counterclockwise direction when viewed from the side of the main body 21, and unless otherwise specified, the directions are both positive and negative directions. encompasses

Meanwhile, the main body 21 may include a protrusion 212 in which at least a portion of the outer surface protrudes inwardly in the radial direction of the main body 21 . Here, the extent to which the protrusion 212 protrudes inward in the radial direction of the body 21 may be greater than the extent to which the O-ring insertion part 211 protrudes inward in the radial direction of the body 21 . In this case, the protrusion 212 may extend along the circumferential direction of the body 21 , and may be provided between two O-ring insertion parts 211 adjacent in the longitudinal direction of the body 21 .

On the other hand, the other end of the injection member 23 may be connected to the inner surface of the protrusion 212 in communication. As the protrusion 212 protrudes inward in the radial direction of the main body 21, a space is formed between the outer surface of the protrusion 212 and the inner surface of the flow tube passage 11c to form a predetermined space 212a. can be (see FIG. 2). The space portion 212a may be used as a space through which the gas supplied from the gas supply member 50 flows, and the gas flowing through the space portion 212a is connected to the injection member 23 connected to the inner surface of the protrusion portion 212 . ) may be supplied to the venturi member 22 through the other end.

The venturi member 22 may serve to form a vortex of the liquid supplied from the outside using the venturi effect. To this end, the venturi member 22 may include a venturi flow path 221 in which gas and liquid are mixed and flowed.

Specifically, the venturi member 22 includes a first downwardly inclined portion 222 that is inclined downward from one end to the other end, a second downward inclined portion 223 that is inclined downward from the other end to one end, and a first downward inclined portion. A neck portion 224 connected between the portion 222 and the second downwardly inclined portion 223 may be included. Here, the cross-sectional area of the first downward slope 222 may decrease from one end to the other end, and the cross-sectional area of the second downward slope 223 may also decrease from the other end to one end. At this time, one end of the injection member 23 may be connected to the neck 224 in communication. As described above, the injection member 23 is connected to the neck 224 at which the flow rate is increased, so that the liquid and the gas can be smoothly mixed in the venturi flow path 221 . As an example, the liquid is introduced through the first downward slope 222 , is mixed with the gas at the neck 224 , and is generated as a dissolved solution, and the generated solution is venturi through the second downward slope 223 . The member 22 may be discharged to the outside.

Meanwhile, a flow rate passing through the venturi channel 221 of the venturi member 22 may be determined according to diameters of one end and the other end of the venturi member 22 . Since the conventional venturi member is coupled to the inside of the pipe, only the flow rate according to the preset diameter of the venturi member is digested, but the venturi member 22 according to an embodiment of the present invention is coupled to the inside of the body 21, As the main body 21 is detachably coupled to the flow pipe 11, if it is necessary to respond to a change in flow rate, select the body 21 to which the venturi member 22 having a diameter suitable for the changed flow rate is selected, and then By combining with (11), it is possible to respond to flow rate changes differently from the prior art. That is, the amount of solution produced by the venturi device 1, ie, the capacity, can be adjusted by this replaceable venturi member 22 .

The plurality of injection members 23 may transmit the gas provided from the gas supply member 50 to the venturi member 22 . In addition, the plurality of ejection members 23 may increase a contact area between the liquid flowing through the venturi member 22 and the gas provided from the gas supply member 50 .

To this end, one end of the spraying member 23 is connected in communication with the protrusion 212 of the main body 21 , and the other end of the spraying bonsai 23 is connected in communication with the neck 224 of the venturi member 22 . can In addition, the plurality of injection members 23 are spaced apart along the circumferential direction of the venturi member 22 so that the gas provided from the gas supply member 50 is radially inside the venturi flow path 221 of the venturi member 22, That is, it can be sprayed toward the radially inner side of the neck 224 . Accordingly, as the liquid forming a vortex in the venturi flow path 221 and the gas injected toward the radially inner side of the venturi flow path 221 collide with each other, the gas may be efficiently dissolved in the liquid.

The valve member 30 may adjust the concentration at which the gas is dissolved in the liquid in the injector unit 20 . To this end, the valve member 30 may be inserted into the bypass pipe 12 of the housing 10 . Accordingly, the valve member 30 can selectively flow the liquid to the bypass pipe 12 of the housing 10 .

On the other hand, the valve member 30 may be inserted into the insertion end 12a of the bypass pipe 12 of the housing 10 , and depending on the degree to which the valve member 30 is inserted into the insertion end 12a, the liquid enters the housing 10 . It may flow additionally to the flow pipe 11 in the bypass pipe 12 . For example, the valve member 30 may be provided as a plug valve, but this is only an example, and the spirit of the present invention is not limited thereto.

In this case, referring to FIG. 2 , the valve member 30 may include an O-ring insertion part 31 in which at least a portion of an outer surface of the valve member 30 protrudes inward in a radial direction. The O-ring insertion part 31 may be formed to extend along the circumferential direction of the valve member 30 . At this time, the O-ring member 32 may be inserted into the O-ring insertion part 31 , and airtightness between the bypass pipe 12 of the housing 10 and the valve member 30 is maintained by the O-ring member 32 . can be

On the other hand, in this embodiment, the valve member 30 has been described as an example that is coupled in a way that is fitted to the insertion end (12a) of the bypass pipe (12), but this is for convenience of description, and this The idea of the invention is not limited. For example, a male thread is formed on at least a portion of an outer surface of the valve member 30 , and a female thread is formed on at least a portion of an inner surface of the insertion end 12a so that the valve member 30 and the insertion end 12a are formed. It is also possible to be screwed together.

As shown in FIGS. 2 and 3 , the stopper member 40 is separated from the injector unit 20 inserted through the supply end 11a of the flow pipe 11 through the supply end 11a of the flow pipe 11 . can be prevented from becoming

To this end, the stopper member 40 may be selectively inserted into the housing 10 . At this time, at least a portion of the stopper member 40 may be inserted into the stopper member insertion hole 14 formed in the housing 10 .

In this case, the stopper member 40 may be provided, for example, in the shape of a column extending in one direction. For example, the stopper member 40 may be inserted into the stopper member insertion hole 14 after the injector unit 20 is inserted through the supply end 11a of the flow pipe 11 . On the other hand, when replacement of the injector unit 20 is required, as the stopper member 40 inserted into the stopper member insertion hole 14 is first separated from the stopper member insertion hole 14, it is inserted into the supply end 11a. The injector unit 20 can be separated from the supply end 11a.

On the other hand, in the present embodiment, the case where the stopper member 40 is coupled to the stopper member insertion hole 14 of the housing 10 in a way that it is fitted as an example has been described as an example, but the spirit of the present invention is not limited thereto . For example, a male thread is formed on at least a portion of an outer surface of the stopper member 40 , and a female thread is formed on at least a portion of an inner surface of the stopper member insertion hole 14 , so that the stopper member 40 is inserted into the stopper member insertion hole. It may be coupled to (14) by a screw coupling method.

The gas supply member 50 may selectively supply gas to the injector unit 20 from the outside. To this end, the gas supply member 50 may be provided to be connectable to the housing 10 . At this time, referring to FIGS. 3 and 6 , the end of the gas supply member 50 is provided in the housing 10 . It may be inserted into the gas supply member insertion hole 13 .

In addition, as shown in FIG. 2 , the gas supply member 50 may be connected in communication with the injection member 23 of the injector unit 20 . The external gas provided through the gas supply member 50 flows in the space portion 212a formed to be spaced apart between the inner surface of the flow tube passage portion 11c and the outer surface of the protrusion 212, and the space portion 212a. The gas flowing in the venturi may be supplied to the plurality of injection members 23 and injected into the venturi member 22 .

On the other hand, in addition to the venturi device 1 as described above, as shown in FIG. 2 , the duct 100 may also be modified in various forms or include various additional devices, and by these modifications and devices, more A high quality solution can be produced. Such a deformable structure and additional devices of the duct 100 will be described in more detail below.

First, the duct 100 may include a nozzle 110 disposed in the flow path 100a thereof. The nozzle 110 may include a body made of a hollow tube extending to a predetermined length, and suction and discharge ports 111 and 112 provided at both ends of the body, respectively. The outlet 112 has a smaller size than the inlet 111 and, accordingly, the liquid introduced into the inlet 111 and discharged to the outlet 112 has an increased flow rate. The nozzle 110, precisely its body, has a diameter (or inner diameter) that gradually decreases from the inlet 111 to the outlet 112, so that the liquid smoothly flows without substantial resistance to the inlet 111 of the nozzle 110. It can flow out through the outlet 112 from the.

Such a nozzle 110, that is, its body is extended and oriented along the flow path 100a within the flow path 100a of the duct 100, as shown in FIG. 2, its inlet 111 and its outlet ( 112 is also arranged and oriented along the flow path 100a, ie, its flow direction. Accordingly, the nozzle 110 causes the liquid to flow in the same direction as the flow direction of the flow path 100a, and is configured to accelerate the liquid during the flow. That is, the suction port 111 of the nozzle 110 sucks the liquid in the same direction as the flow direction in the flow path 100a, and the discharge port 112 discharges the liquid in the same direction as the flow direction. Accordingly, the nozzle 110 can be configured to accelerate the fluid in the flow path 100a in the same flow direction without any loss.

In addition, the duct 100 may include a chamber 120 of a predetermined size provided in the flow path 100a thereof. The chamber 120 may be disposed at the outlet 112 of the nozzle 110 to receive the liquid discharged from the nozzle 110 . More specifically, the chamber 120 is disposed in the duct 100 to communicate with the flow path 110a, and may be located downstream of the nozzle 110 . In addition, the chamber 120 communicates with at least the outlet 112 of the nozzle 110 , and accordingly, the liquid discharged to the exposure 110 may be immediately accommodated in the chamber 120 . Furthermore, in order to stably receive the discharged liquid, the chamber 120 partially accommodates therein the end of the nozzle 110 including the outlet 112 , and thus the outlet 112 is also the chamber 120 . can be accommodated in That is, the end including the outlet 112 of the nozzle 110 may be partially inserted into the chamber 120 .

More specifically, the chamber 120 is connected to the suction port 121 connected to the flow path 100a to introduce the liquid therein and the flow path 100a to discharge the introduced liquid into the flow path 100a. It may include an outlet 122 that is. The inlet 121 and the outlet 122 of the chamber 121 are disposed and oriented along the flow path 100a, that is, the flow direction thereof. Therefore, the chamber 120 is formed as a part of the flow path 100a, basically configured to allow the liquid to flow in the same direction as the flow direction of the flow path 100a so as not to obstruct the flow of the liquid like the nozzle 110. do. As shown, the nozzle 110 is actually tightly fitted into the inlet 121 of the chamber 121 and may be partially inserted into the inner space of the chamber 120 through the inlet 121 . Accordingly, as mentioned above, the outlet 112 of the nozzle 110 is disposed in the chamber 121 to directly discharge the liquid into the chamber 121 .

In addition, the chamber 120 may include an auxiliary suction port 123 configured to communicate with the venturi device 1 and introduce the generated solution into the chamber 120 . In more detail, the auxiliary suction port 123 is directly connected to the suction port 102a of the duct 100 , and thus may communicate with the second auxiliary duct 102 . Accordingly, the chamber 120 can be directly connected to the venturi apparatus 1, precisely the discharge end 11b thereof, through the auxiliary inlet 123, the inlet 102a and the second auxiliary duct 102. For this reason, the chamber 120 may receive the generated solution from the venturi apparatus 1 . That is, the venturi device 1 may be configured to discharge the generated solution to the chamber 120 .

As described above, since the liquid accelerated by the nozzle 110 is primarily discharged into the chamber 120, a relatively low pressure state, that is, the negative pressure in the chamber 120 due to the high flow rate of the discharged liquid. environment can be created. Therefore, the solution generated in the venturi device 1 due to this negative pressure environment can be more smoothly sucked into the chamber 120 through the second auxiliary duct 102 , the suction port 102a and the auxiliary suction port 123 . . In practice, the flow rate of the lysate can be substantially increased by the negative pressure environment during such inhalation. The accelerated solution collides with the liquid accelerated by the nozzle 110 in the chamber 120 as well, and the gas in the solution may be split into smaller sizes by this collision. In addition, a vortex is largely generated by such collision, and the gas decomposed by the generated vortex can be better dissolved in the liquid. Therefore, by the configuration of the duct 100 described above, that is, the chamber 120 for mixing the liquid supplied from the nozzle 110 and the dissolved liquid supplied from the venturi apparatus 1, not only a smaller size of gas bubbles but also more A high quality solution with a large amount of dissolved gas (ie, increased solubility or gas concentration) can be produced. The solution additionally treated in this way may be supplied to an intended external device along the flow path 100a through the outlet 122 of the chamber 120 .

Further, to further improve the quality of the solution, the venturi device 1 may be configured to discharge the solution to the side of the nozzle 110 , as well shown in FIG. 2 . When the solution is discharged to the side of the nozzle 110, the solution collides with the side of the nozzle 110 in addition to collision with the sprayed liquid. In addition, the collided solution naturally forms a rotational flow or vortex while turning along the side of the nozzle 110 . Such additional collisions and vortices further promote the formation of small gas bubbles and an increase in solubility or gas concentration for the same reasons as described above, and the quality of the dissolved solution can be further improved. As shown in FIG. 2 , the auxiliary suction port 123 of the chamber 120 may be disposed to face the side of the nozzle 110 to discharge the solution to the side of the nozzle 110 in this way. Also, for the same purpose, the nozzle 110 may be extended to the inside of the chamber 120 so that the discharge port 112 of the nozzle may be disposed beyond the auxiliary suction port 123 . Such a configuration allows the solution to be discharged to the side of the nozzle 110, and can ensure the aforementioned effect.

In addition, as shown in FIG. 2 , the pipe 100 may include an expansion pipe 130 provided in the flow path 100a. The expansion tube 130 may be formed as a part of the flow path 100a and may be disposed downstream of the chamber 120 to communicate with the chamber 120 . In more detail, the pipe expansion unit 130 discharges the inlet 131 connected to the chamber 120 to introduce the dissolved water in the chamber 120 to the inside and the introduced dissolved water to the flow path 100a. It may include an outlet 132 connected to the flow path (100a) to do so. The inlet 131 and the outlet 132 of the expansion tube 130 are arranged and oriented along the flow path 100a, that is, the flow direction thereof. Therefore, the expansion tube 130 also basically flows the dissolved solution processed in the chamber 120 in the same direction as the flow direction of the flow path 100a so as not to interfere with the flow of the liquid like the nozzle 110 and the chamber 120 . It is designed to allow

In addition, the inlet 131 of the expansion tube 130 is directly connected to the outlet 122 of the chamber 120, and is configured to communicate with the outlet 112 of the nozzle 110 in the chamber 120 at the same time. More specifically, the inlet 131 of the expansion tube 130 may be aligned with the outlet 112 of the nozzle 110 and the outlet 122 of the chamber 120 . Furthermore, the inlet 131 of the expansion tube 130 may be arranged concentrically with the outlet 112 of the nozzle 110 and the outlet 122 of the chamber 120 , that is, on a common central axis. Due to this arrangement, the solution in the chamber 120 can smoothly flow into the flow path 100a directly through the expansion tube 130 without substantial resistance, that is, without loss. In addition, due to the gradually expanding structure, the flow rate of the dissolved solution in the expansion tube 130 is lowered, and thus the gas may have sufficient time to be dissolved in the liquid additionally. Therefore, such an expansion part 130 can further improve the quality of the generated solution.

Furthermore, due to the configuration described above, the nozzle 110 and the expansion tube 130 are fluidly connected to each other and can substantially form an additional venturi structure, and dissolution of additional gas can be performed using this. . More specifically, the pipe 100 is disposed adjacent to the outlet 112 of the nozzle 110, and may include an injection pipe 140 configured to discharge gas to the outlet 112 of the nozzle 110. can A supply pipe 141 may be connected to the pipe 100 to supply gas to the injection pipe 140 . For practically stable gas injection, the injection pipe 140 is disposed at the outlet 122 of the chamber 120 and/or the inlet 131 of the expansion pipe 130 corresponding to the neck of the formed venturi structure. gas can be sprayed. Gas may be additionally dissolved in the solution by the injected gas, and solubility and gas concentration of the solution may be substantially improved.

In addition, the duct 100 may additionally include a stirrer 150 configured to form a vortex in the liquid of the flow path (100a). The agitator 150 is provided in the flow path 100a and may be disposed at the suction port 111 of the nozzle 110 . The agitator 150 may be implemented according to various mechanisms for forming a vortex, and may be formed of, for example, a blade, an impeller, or a spiral flow path. A vortex is already formed in the liquid supplied to the nozzle 110 by the agitator 150 , and such a vortex can be formed when discharged. Accordingly, the liquid in the chamber 120 can be mixed with the solution more smoothly.

On the other hand, the dissolution device may further include an additional device to improve the quality of the solution in addition to the configuration of the duct 100 described above. As an example, as shown in FIG. 2 , the dissolving device may further include a magnetizing device 200 installed in the duct 100 to magnetize the liquid in the duct 100 . When a liquid is magnetized, radicals are formed therein, and the radicals can impart several additional useful properties to the liquid. Such a magnetization device 200 will be described in more detail below with reference to FIG. 2 and additionally related drawings.

9 is an exploded perspective view and a partial cross-sectional view showing the magnetization device included in the melting apparatus of FIG. 1, and FIG. 10 is a cross-sectional view showing examples of cross-sections of the holder of FIG.

Referring to FIGS. 9 and 10 in addition to FIG. 2 , the magnetization device 200 is provided on the outer periphery of the duct 100 and may include a mounter 210 configured to surround the duct 100 . have. The mounter 210 functions as a platform for mounting other components of the magnetization device 200 to be described later to the duct 100 . More specifically, the mounter 210 may include a sleeve 210a mounted thereon while surrounding the duct 100 and flanges 210b provided at both ends of the sleeve 210a. The flange 210b may extend a predetermined length in a radial direction from both ends of the sleeve 210a.

In addition, the magnetization device 200 is installed on the mounter 210 and may include a plurality of holders 220 arranged at predetermined intervals along the circumferential direction of the mounter 210 . The holders 220 may be formed of a member in the form of a rod extending long, and may be actually installed on the flange 210b of the mounter 210a. More specifically, the flange 210b includes a plurality of seats 210c, and these seat portions 210c may be formed of a recess or a through hole. Accordingly, both ends of the holder 220 are fitted to the seat portion 210c of the flange 210b, and thus the holder 220 may be mounted on the mounter 210 .

Furthermore, the magnetization device 200 may include a permanent magnet 230 disposed in each holder 220 . The permanent magnet 230 actually forms a magnetic field to magnetize the liquid in the duct 100 . If the permanent magnet 230 protrudes to the outside of the holder 220, the volume of the magnetizing device 200 increases, making installation and maintenance difficult. For this reason, the permanent magnets 230 may be embedded in each of the holders so as not to protrude to the outside. As an example, the holder 220 may include through-holes 220a formed in a radial direction or a width direction, and may be embedded in the through-holes 220a so that the permanent magnet 230 does not protrude. In addition, the holder 220 may also be made of a strong magnetic material, and thus a stronger magnetic field may be formed.

In this case, generally, as shown in FIG. 10( a ), the magnetic material holder 220 may have a smooth outer surface. However, when the holder 220 has a polygonal cross section, as shown in FIGS. For this reason, the holder 220 preferably has a polygonal cross section as shown in FIGS. 10(b) and (c). As an example, FIG. 10( b ) shows a holder 220 having a pentagonal cross-section with five surfaces from which lines of magnetic force are emitted. In addition, FIG. 10( c ) shows the holder 220 of a cross-section of a serration shape, and includes more surfaces than FIG. 10( c ), which is advantageous for the formation of a stronger magnetic field.

Such a magnetization device 200 may be provided not only in the duct 100 but also in the first and second auxiliary ducts 101 and 102, and in this case, a higher quality solution may be generated.

Hereinafter, with reference to FIGS. 11 and 12, the action and effect of the dissolving device having the configuration as described above will be described as follows.

Referring to FIG. 11 , the injector unit 20 is inserted through the supply end 11a of the flow pipe 11 provided in the housing 10 . When the insertion of the injector unit 20 is completed, the stopper member 40 is inserted into the stopper member insertion hole 14 pre-installed in the housing 10 so that the injector unit 20 is not separated from the flow pipe 11 , thereby making the housing The installation of the injector unit 20 for (10) is completed. Next, the gas supply member 50 is connected to the gas supply member insertion hole 13 previously installed in the housing 10 . Finally, the duct 100 is connected to the housing 10 , that is, the venturi device 1 using the auxiliary ducts 101 and 102 , ready to generate a solution.

Thereafter, the liquid is supplied to the venturi apparatus 1 using the duct 100 from the outside through the supply end 11a of the flow pipe 11 . At this time, since the valve member 30 is completely inserted into the insertion end 12a of the bypass pipe 12 provided inside the housing 10 , the liquid supplied from the outside is not diverted to the bypass pipe 12 . Instead, it may be supplied only to the flow pipe 11 .

Meanwhile, the supplied liquid flows along the venturi flow path 221 provided in the venturi member 22 of the injector unit 20 to form a vortex. At this time, the gas provided from the gas supply member 50 is supplied to the venturi flow path 221 through the plurality of ejection members 23 and is dissolved in the liquid while colliding with the vortex of the liquid. The dissolved liquid in the liquid in which the gas is dissolved may pass through the venturi flow path 221 and be discharged through the discharge end 11b of the flow pipe 11 .

On the other hand, referring to FIG. 12 , as the degree of insertion of the valve member 30 inserted into the insertion end 12a of the bypass pipe 12 is adjusted, the inlet of the bypass pipe 12 may be opened, , at least a portion of the liquid supplied from the outside may be diverted to the bypass pipe (12). Due to this bypass, the flow rate of the liquid supplied to the injector unit 20 is reduced, and the reduced flow rate also brings about a decrease in the pressure inside the injector unit 20 . Accordingly, as the pressure of the gas injected from the plurality of injection members 23 of the injector unit 20 is relatively increased due to the decrease in internal pressure, the amount of the injected gas may also increase. Accordingly, the amount of gas dissolved in the liquid in the injector unit 20 , that is, the gas concentration of the dissolved liquid may be increased. That is, as the amount of fluid and fluid pressure supplied to the injector unit 20 is reduced by the bypass of the fluid through the bypass pipe 12, the gas pressure and the amount of gas supplied are increased, and a higher gas concentration ( That is, a solution having solubility) may be produced.
