Description

High-efficiency vortex generator for water treatment system and water treatment system having the same

The present invention relates to a vortex generator for a water treatment system used in a water treatment system for treating sewage, wastewater, sewage, industrial processing water, etc., and a water treatment system having the same, and more particularly, to a high-efficiency vortex generator for the water treatment system It relates to a device and a water treatment system having the same.

In general, water treatment systems treat sewage, wastewater, sewage, industrial processing water, and the like in various ways. For example, in a water treatment system that treats wastewater using a treatment tank, wastewater is accommodated in the treatment tank, and then aerobic bacteria such as bacteria of the genus Bacillus are proliferated or supplied in the treatment tank to treat the wastewater. In this case, in order to improve the efficiency of water treatment, it is necessary to supply enough oxygen to the treatment tank so that aerobic bacteria propagate and work smoothly.

To this end, the "bubble generator" described in Japanese Patent Office Patent No. 4749961 proposes a device that generates fine bubbles in sewage to propagate aerobic bacteria.

In addition, the “low-energy, water flow diffusion type micro-bubble generator” described in the Korean Intellectual Property Office Registration No. 10-1834183 proposes a device that converts the wastewater in the treatment tank into a vortex state so that the micro-bubbles are smoothly diffused.

In such a water treatment system, in order to improve water treatment efficiency, it is necessary that air supplied from the outside to the treatment tank is sufficiently dispersed into the wastewater in the treatment tank so that oxygen contained in the air is sufficiently supplied to aerobic bacteria in the wastewater. As air passes through a path from the outside to the treatment tank, the flow rate gradually decreases, so that it is difficult to substantially disperse the air sufficiently into the wastewater in the treatment tank.

Therefore, in the water treatment system, the flow rate of air supplied from the outside to the treatment tank is prevented from gradually decreasing as it passes from the outside to the treatment tank, so that the air is sufficiently dispersed in the wastewater in the treatment tank and the oxygen contained in the air is aerobic in the wastewater. There is a need to develop a high-efficiency vortex generator for a water treatment system that can be sufficiently supplied to bacteria to improve water treatment efficiency and a water treatment system equipped with the same.

Furthermore, the high-efficiency vortex generating device 100 for a water treatment system according to the present embodiment may further include a microbubble generating unit 150 and a support unit 160.

The high-efficiency vortex generator 100 for a water treatment system according to the present embodiment is a device that generates vortexes to enable high-efficiency water treatment in a water treatment system that treats sewage or wastewater in the treatment tank 10.

Here, the treatment tank 10 refers to a bath in which sewage or wastewater is introduced from an object that generates sewage or wastewater, is accommodated, and is treated.

Here, the sewage or wastewater refers to sewage or wastewater that can be treated by aerobic bacteria such as bacteria of the genus Bacillus, and such sewage or wastewater includes, for example, sewage, wastewater, sewage, or industrial processing water. can be included Hereinafter, such sewage or wastewater is referred to as sewage.

Here, the vortex means a vortex generated in the treatment tank 10 . The vortex may include a vortex of air containing oxygen supplied from the outside of the treatment tank 10 to the sewage inside the treatment tank 10 and a vortex of sewage generated inside the treatment tank 10 by the air vortex. there is. In the vortex of sewage generated inside the treatment tank 10 by the air vortex, the vortex of the sewage generated inside the vortex generator arranged to be located inside the sewage accommodated inside the treatment tank 10 and the outside of the vortex generator Vortex of sewage generated inside the treatment tank 10 may be included. However, the vortex is not limited thereto and may include other various types of vortex.

The chamber 110 is a device that converts air injected from the outside into a vortex and discharges it to the outside. As a result, a vortex is generated in the sewage inside the chamber 110 and discharged to the outside, and as the sewage inside the chamber 110 is discharged to the outside, the sewage received inside the treatment tank 10 outside the chamber 110 is discharged to the outside of the chamber ( 110) is introduced into the interior, and then the sewage introduced into the chamber 110 is continuously injected into the chamber 110 and converted into a vortex, converted into a vortex by the discharged air, and then discharged to the outside of the chamber 110 . In this process, the sludge accumulated at the bottom of the treatment tank 10 flows, thereby preventing sludge accumulation and preventing anaerobicization of the sludge at the bottom of the treatment tank 10, as well as smooth mixing of air and sewage. As a result, the propagation and activity of aerobic bacteria are greatly increased, and the treatment efficiency of sewage is improved.

The chamber 110 may be composed of various configurations capable of converting air injected from the outside into a vortex and discharging it to the outside. For example, the chamber 110 may include a main body 111, an inlet 112, and an outlet 113, as exemplarily shown in FIG. 2 .

The main body 111 is a part that forms a vortex while passing air along its central axis, as exemplarily shown in FIG. 3 . The main body 111 has an interior through which air can pass through along its central axis to form a vortex. The inside of the main body 111 may be formed in various shapes. For example, as illustrated in FIG. 4 , the inside of the main body 111 is formed in a cylindrical shape so that air can easily form a vortex while penetrating the inside of the main body 111 . However, the inside of the main body 111 is not limited thereto and may be formed in various other shapes such as an oval. The length and cross-sectional area of the main body 111 may be appropriately adjusted to treat sewage in the treatment tank 10 .

The inlet 112 is a part through which sewage in the treatment tank 10 flows into the main body 111 . As the sewage inside the main body 111 is discharged to the outside of the main body 111, the sewage received inside the treatment tank 10 outside the main body 111 flows into the inside of the main body 111. In this way, the inside of the main body 111 The inflowing sewage is introduced through the inlet 112 . The inlet 112 may have various shapes through which sewage in the treatment tank 10 may flow into the main body 111 . For example, the inlet 112, as exemplarily shown in FIG. 4, is formed in the shape of a circular hole at the lower end of the cylindrical body 111 so that sewage inside the body 111 is removed from the upper body As it is discharged to the outside through the discharge part 113 of the main body 111, sewage from the lower outside of the main body 111 can be easily introduced into the inside of the main body 111. In this case, if the inlet 112 is arranged to be separated from the bottom of the treatment tank 10 by a predetermined distance, sewage from the lower exterior of the main body 111 can be smoothly introduced into the main body 111 .

The discharge part 113 is a part through which sewage inside the main body 111 is discharged to the outside of the main body 111 . The sewage introduced into the main body 111 is injected into the main body 111, converted into a vortex, and then converted into a vortex by the air discharged to the outside of the main body 111, and then discharged to the outside of the main body 111. As such, Sewage discharged to the outside of the main body 111 is discharged through the discharge unit 113 . The discharge unit 113 may be formed in various shapes through which sewage inside the main body 111 is discharged to the outside of the main body 111 . For example, the discharge unit 113, as exemplarily shown in FIG. 4, is formed in a circular hole shape at the upper end of the cylindrical body 111 so that it is injected into the body 111 and converted into a vortex, then the body (111) It can be easily discharged to the outside of the main body 111 by the air discharged to the outside. In this case, the discharge unit 111 is arranged so as to be separated from the surface of the sewage received in the treatment tank 10 by a predetermined distance so that the sewage inside the main body 111 passes through the discharge unit 111 to the upper side of the main body 111. It can be smoothly discharged as sewage accommodated in the external treatment tank 10 .

The air introduction part 120 is a part through which air introduced into the treatment tank 10 from the outside of the treatment tank 10 passes. Accordingly, air may be introduced into the vortex generator 100 inside the treatment tank 10 from the outside of the treatment tank 10 . The air inlet 120 is connected to an air supply source located outside the treatment tank 10 to receive air.

The air inlet 120 has a length and cross-sectional area that allows air to be introduced into the vortex generator 100 from an air supply source.

The air inlet 120 may extend from an air supply source to have various shapes. For example, the air inlet 120 is illustratively, as shown in FIGS. 1 to 3, from the central axis of the chamber 110 along the central axis direction of the chamber 110 to the outer surface of the chamber 110. It may include an extension 121 extending to be located within a vertical distance to an adjacent part. As a result, since the volume in the horizontal direction perpendicular to the central axis direction of the chamber 110 of the vortex generator 100 including the air inlet 120 can be miniaturized, the vortex including the air inlet 120 When the generator 100 is installed in the treatment tank 10, the vortex generator 100 can be smoothly operated through the small inlet 11 that can be opened and closed by the door 12 formed on the cover covering the upper part of the treatment tank 10. It can be easily installed in the treatment tank 10 by injection.

The air accelerator 130 is a part that accelerates and discharges air introduced from the air inlet 120 while flowing. Air introduced from the outside of the treatment tank 10 is accelerated at a high speed by the air accelerator 130 and supplied to the inside of the main body 111 of the chamber 110, so that the air is blown inside the main body 111 of the chamber 110 at high speed. It is converted into a vortex having a flow rate of and is discharged to the outside of the main body 111 of the chamber 110. The sewage received inside the main body 111 of the chamber 110 by the air vortex having a high flow rate inside the body 111 of the chamber 110 is converted into a vortex having a high flow rate, and the chamber 110 together with the air vortex ) is discharged at high speed through the discharge unit 113 to the outside of the main body 111. In this process, the air vortex and the sewage vortex prevent the flow velocity of the other side from being reduced by interaction and improve the mixing with the other side by mutual close contact, so that the oxygen contained in the air vortex is smoothly supplied to the sewage vortex. Furthermore, as the sewage accommodated inside the body 111 of the chamber 110 is discharged to the outside of the body 111 at high speed through the discharge unit 113, the sewage received in the treatment tank 10 outside the body 111 flows in. By flowing into the body 111 at high speed through the part 112, the sludge accumulated on the bottom of the treatment tank 10 flows. Therefore, the breeding and activity of aerobic bacteria included in the sewage in the treatment tank 10 is greatly increased, thereby significantly increasing the efficiency of sewage treatment.

The air accelerator 130 may have various shapes in which air introduced from the air inlet 120 is accelerated at a high speed while flowing, and discharged. For example, the air accelerator 130 may include a first end 131 , an accelerator 132 and a second end 133 .

The first end 131 is a portion where the air accelerator 130 is connected to the air inlet 120 and air is introduced from the air inlet 120 . The first end 131 may be integrally connected to the air inlet 120, but is not limited thereto and may be detachably connected to the air inlet 120 as needed.

The accelerator 132 may have various shapes in which air introduced through the first end 131 can be accelerated while flowing. For example, the accelerator 132 extends from the first end 131 and has a cross-sectional area smaller than the cross-sectional area of the air inlet 120, as shown in FIGS. 2 and 3 by way of example. Air introduced from the air inlet 120 having a larger cross-sectional area through the end 131 may increase its flow rate while passing through the accelerator 132 having a smaller cross-sectional area. Furthermore, the accelerator 132 gradually reduces the cross-sectional area from the first end 131 to the second end 132 so that the air inlet 120 has a larger cross-sectional area through the first end 131. The flow rate may be gradually increased while the air introduced from ) passes through the accelerator 132 having a gradually smaller cross-sectional area.

The accelerator part 132 has a length and a cross-sectional area through which air introduced through the first end 131 can be accelerated while flowing.

The accelerator 132 may extend from the air inlet 120 to have various shapes. For example, the accelerator 132 may extend along the central axis of the chamber 110 so as to be adjacent to the outer surface of the main body 111 of the chamber 110, as illustrated in FIGS. 2 and 3 . . As a result, since the volume in the horizontal direction perpendicular to the central axis direction of the chamber 110 of the vortex generator 100 including the accelerator 132 can be miniaturized, the vortex generator including the accelerator 132 In installing the vortex generator 100 in the treatment tank 10, the vortex generating device 100 can be smoothly injected even through a small door formed on the cover covering the upper part of the treatment tank 10 to be easily installed in the treatment tank 10. be able to

The second end 133 is a part that is connected to the air blowing part 140 and discharges the air accelerated by the accelerating part 132 to the air blowing part 140 . The second end 133 may be integrally connected to the air blowing unit 140, but is not limited thereto and may be detachably connected to the air blowing unit 140 as needed.

The air injection unit 140 is supplied with air accelerated from the air acceleration unit 130 through one end connected to the second end 133 of the air acceleration unit 130, inside the main body 111 of the chamber 110 This is a part through which accelerated air is injected so that a swirling vortex is generated along the inner surface of the main body 111 of the chamber 110 into the inside of the main body 111 of the chamber 110 through the other end connected to.

Accelerated air is injected into the main body 111 of the chamber 110 by the air blowing unit 140 so that a swirling vortex is generated along the inner surface of the main body 111 of the chamber 110, so that the air is blown into the chamber 110. It is converted into a vortex having a high flow rate inside the body 111 of the chamber 110 and discharged to the outside of the body 111 of the chamber 110. The sewage received inside the main body 111 of the chamber 110 by the air vortex having a high flow rate inside the body 111 of the chamber 110 is converted into a vortex having a high flow rate, and the chamber 110 together with the air vortex ) Is discharged to the outside of the main body 111. In this process, the air vortex and the sewage vortex prevent the flow velocity of the other side from being reduced by interaction and improve the mixing with the other side by mutual close contact, so that the oxygen contained in the air vortex is smoothly supplied to the sewage vortex.

The air injection unit 140 has various shapes for injecting accelerated air so that a swirling vortex is generated along the inner surface of the main body 111 of the chamber 110 by the accelerated air introduced from the air accelerator 130. can For example, the air injection unit 140, as illustratively shown in FIG. 4, the air to be injected is injected along a direction crossing the central axis of the chamber 110 and tangential to the inner surface of the main body 111. It may be arranged so that As a result, the accelerated air injected along the tangential direction to the inner surface of the main body 111 minimizes deceleration due to collision with the inner surface of the main body 111 so that it can smoothly turn at high speed along the inner surface of the main body 111. do.

Furthermore, the air blowing unit 140 may further accelerate the accelerated air introduced from the air accelerating unit 130 by having a cross sectional area smaller than that of the air accelerating unit 130 . As a result, the air accelerated to have a flow rate greater than that of the air accelerated by the air accelerator 130 is sprayed into the body 111 of the chamber 110, so that the air moves inside the body 111 of the chamber 110. It is converted into a vortex with a higher velocity and discharged to the outside of the main body 111 of the chamber 110. The sewage received inside the main body 111 of the chamber 110 is converted into a vortex having a higher high-speed flow rate by the air vortex having a higher speed flow rate inside the main body 111 of the chamber 110 and Together, the main body 111 of the chamber 110 is discharged at a higher speed through the discharge unit 113. In this process, the air vortex and the sewage vortex prevent the flow velocity of the other side from being reduced by a larger interaction and further improve the mixing with the other side by a larger mutual contact, so that the oxygen contained in the air vortex is more concentrated in the sewage vortex. supplied smoothly. Furthermore, as the sewage received inside the main body 111 of the chamber 110 is discharged to the outside of the main body 111 at a higher speed through the discharge part 113, the inside of the main body 111 is further passed through the inlet part 112. As the sewage accommodated in the treatment tank 10 outside the main body 111 flows in at high speed, the sewage contained in the treatment tank 10 is more smoothly converted into a vortex flow, and the sludge accumulated at the bottom of the treatment tank 10 flows more It becomes. Therefore, the breeding and activity of aerobic bacteria included in the sewage in the treatment tank 10 are further greatly increased, thereby further significantly increasing the efficiency of sewage treatment.

Furthermore, the air blowing unit 140 gradually reduces the cross-sectional area from the end connected to the air accelerating unit 130 to the end blowing air into the main body 111 of the chamber 110, thereby reducing the amount of air injected. The flow rate can be increased gradually.

The air spraying unit 140 generates a swirling vortex along the inner surface of the main body 111 of the chamber 110 as the air introduced from the air accelerating unit 130 is sprayed into the main body 111 of the chamber 110. It has an acceptable length and cross-sectional area.

The air blowing unit 140 may extend from the air accelerating unit 130 to have various shapes. For example, the air blowing unit 140 may be bent from the air accelerating unit 130 and extend toward the inside of the main body 111 of the chamber 110, as illustrated in FIGS. 2 and 3 . Here, the direction in which the air blowing part 140 extends toward the inside of the main body 111 of the chamber 110 is the direction in which the air injected into the main body 111 crosses the central axis of the chamber 110, and the main body 111 ) may be a direction such that it is sprayed along a direction tangential to the inner surface.

The air blowing part 140 may protrude into the body 111 of the chamber 110 by penetrating the outer surface of the chamber 110 so that an air blowing end may protrude into the chamber 110 . However, the air blowing end of the air blowing unit 140 is not limited thereto and may coincide with a hole formed on a side surface of the main body 111 without protruding into the inside of the main body 111 of the chamber 110 . The air blowing end of the air blowing unit 140 is a predetermined distance from the inlet 112 of the main body 111 of the chamber 110 toward at least the central part of the main body 111, for example, the injected air is blown into the inlet ( 112), it is preferable to be spaced apart by a distance enough to move toward the center of the main body 111 without leaking.

The micro-bubble generator 150 is a part that generates micro-bubbles from air vortexes swirling along the inner surface of the main body 111 of the chamber 110. As a result, the fine bubbles generated from the air vortex turning along the inner surface of the main body 111 of the chamber 110 are converted into vortexes inside the main body 111 as well as the sewage accommodated inside the main body 111 of the chamber 110 Oxygen contained in the air can be smoothly transferred to the sewage by moving in close contact with the sewage, and accordingly, the propagation and activity of aerobic bacteria contained in the sewage are greatly increased, thereby greatly increasing the efficiency of sewage treatment.

The micro-bubble generator 150 may have various configurations that generate micro-bubbles from air vortexes turning along the inner surface of the main body 111 of the chamber 110 . For example, as illustrated in FIGS. 3 and 4, the microbubble generating unit 150 includes a plurality of protrusions protruding from the inner surface of the main body 111 toward the central axis of the main body 111 of the chamber 110. can be made with Here, it is preferable that the plurality of protrusions are arranged on the path along which the air vortex turns along the inner surface of the main body 111 of the chamber 110 . Here, the degree of protrusion of the plurality of protrusions may be made in various ways. For example, as shown in FIG. Protrusions arranged on the same and different cross sections may have different degrees of protrusion.

The support part 160 is a part that supports the chamber 110 so that the chamber 110 is separated from the bottom of the treatment tank 10 by a predetermined distance. As a result, the vortex generator 100 including the chamber 110 can be stably installed in the treatment tank 10, through the inlet 112 formed at the lower end of the body 111 of the chamber 110. Sewage can be smoothly introduced into the main body 111 from the lower outside of the main body 111 .

The support part 160 may have various configurations capable of supporting the chamber 110 so that the chamber 110 is separated from the bottom of the treatment tank 10 by a predetermined distance. For example, as shown in FIGS. 1 to 3, the upper portion of the support portion 160 is coupled to the lower outer surface of the main body 111 of the chamber 110 and the lower portion is the main body of the chamber 110. (111) may be formed of a plurality of support bars extending downward from the bottom of the outer side surface.

The operation of the high-efficiency vortex generator 100 for a water treatment system according to this embodiment will be described.

First, the high-efficiency vortex generator 100 for a water treatment system is injected into the sewage through the surface of the sewage accommodated in the treatment tank 10, and the support part 160 is supported on the bottom of the treatment tank 10, so that the treatment tank 10 installed If the upper part of the treatment tank 10 is covered with a cover, as exemplarily shown in FIG. The sewage water received in the treatment tank 10 is injected into the sewage through the water surface and installed on the bottom of the treatment tank 10 . At this time, the high-efficiency vortex generator 100 for a water treatment system installed at the bottom of the treatment tank 10 is installed by fixing the air inlet 120 connected to the outside of the treatment tank 10 to a predetermined location outside the treatment tank 10. It can be stably fixed in place. Therefore, the high-efficiency vortex generator 100 for a water treatment system according to the present embodiment can be easily installed or replaced without the need to remove the sewage while the sewage is accommodated in the treatment tank 10.

When the high-efficiency vortex generator 100 for the water treatment system is installed in the treatment tank 10, air is introduced into the air inlet 120 from an air supply source outside the treatment tank 10. Subsequently, the air introduced into the air accelerator 130 from the air inlet 120 passes through the air accelerator 130 having a smaller cross-sectional area than the air inlet 120, and the flow rate increases.

After the air introduced from the outside of the treatment tank 10 is accelerated at high speed by the air accelerator 130 , it is injected into the main body 111 of the chamber 110 at high speed through the air sprayer 140 . The air injected at high speed into the main body 111 of the chamber 110 is converted into a vortex having a high speed flow that turns along the inner surface of the main body 111 of the chamber 110, and the main body 111 of the chamber 110 It is discharged to the outside at high speed. At this time, the sewage received inside the body 111 of the chamber 110 by the air vortex having a high flow rate inside the main body 111 of the chamber 110 is converted into a sewage vortex having a high flow rate, and the air vortex and the chamber It is discharged at high speed through the discharge part 113 to the outside of the body 111 of the body 110.

In this process, the high-speed air vortex and the high-speed sewage vortex prevent the flow velocity of the other side from being reduced by interaction and improve the mixing with the other side by mutual close contact, so that the oxygen contained in the air vortex flows smoothly into the sewage vortex. will be supplied Furthermore, as the sewage received inside the body 111 of the chamber 110 is discharged to the outside of the body 111 at high speed through the discharge unit 113, the body 111 enters the body 111 at high speed through the inlet unit 112. (111) Sewage contained in the external treatment tank 10 flows in, and as this process is repeated, the sewage contained in the treatment tank 10 is converted into a vortex passing through the inside of the main body 111 of the chamber 110. At this time, sludge accumulated on the bottom of the treatment tank 10 flows while sewage received in the treatment tank 10 outside the main body 111 flows into the main body 111 at high speed through the inlet 112 . Therefore, the breeding and activity of aerobic bacteria included in the sewage in the treatment tank 10 is greatly increased, thereby significantly increasing the efficiency of sewage treatment.

A high-efficiency vortex generator 200 for a water treatment system according to another embodiment of the present invention, as exemplarily shown in FIGS. 5 and 6, the chamber 210, the air inlet 220, the first It includes an air accelerator 230 , a first air ejector 240 , a second air accelerator 250 and a second air ejector 260 . Furthermore, the high-efficiency vortex generating device 200 for a water treatment system according to the present embodiment may further include a microbubble generating unit 270 and a support unit 280.

The high-efficiency vortex generator 200 for a water treatment system according to the present embodiment is a device that generates vortexes to enable high-efficiency water treatment in a water treatment system for treating sewage or wastewater in the treatment tank 10 .

Here, the treatment tank 10 refers to a tank in which sewage or wastewater is received from an object that generates sewage or wastewater, is received, and is treated.

Here, the sewage or wastewater refers to sewage or wastewater that can be treated by aerobic bacteria such as bacteria of the genus Bacillus, and such sewage or wastewater may include, for example, sewage, wastewater, sewage, or industrial processing water. there is. Hereinafter, such sewage or wastewater is referred to as sewage.

Here, the vortex means a vortex generated in the treatment tank 10 . In these vortices, two vortices of air containing oxygen supplied from the outside of the treatment tank 10 to the sewage inside the treatment tank 10 and two vortices of air generated inside the treatment tank 10 by these two air vortexes Eddy currents of effluent may be included. In the two vortexes of sewage generated inside the treatment tank 10 by the two air vortices, the two vortexes of sewage generated inside the vortex generator arranged to be located inside the sewage accommodated in the treatment tank 10 And, two vortexes of sewage generated inside the treatment tank 10 outside the vortex generator may be included. However, the vortex is not limited thereto and may include other various types of vortex.

The chamber 210 is a device that converts two air jets injected from the outside into two vortexes and discharges them to the outside. As a result, two vortices are generated in the sewage inside the chamber 210 and discharged to the outside, and as the sewage inside the chamber 210 is discharged to the outside, the sewage accommodated in the treatment tank 10 outside the chamber 210 The sewage introduced into the chamber 210, and then the sewage introduced into the chamber 210 is continuously injected into the chamber 210 and converted into vortexes, and then converted into two vortexes by the two air discharged into the chamber ( 210) is discharged to the outside. In this process, the sludge accumulated at the bottom of the treatment tank 10 flows, thereby preventing sludge accumulation and preventing anaerobicization of the sludge at the bottom of the treatment tank 10, as well as doubling the mixing of air and sewage. By making it very smooth, the propagation and activity of aerobic bacteria are greatly increased, such as doubling, and the treatment efficiency of sewage is greatly improved, such as doubling.

The chamber 210 may be configured in various configurations capable of converting two air jets injected from the outside into two vortexes and discharging them to the outside. For example, the chamber 210 may include a body 211, an inlet 212, and an outlet 213, as shown in FIG. 5 as an example.

The main body 211 is a part that forms two vortices while passing two airs along its central axis. The body 211 has an interior capable of forming two vortices while passing two airs along its central axis. The inside of the main body 211 may be formed in various shapes. For example, since the inside of the main body 211 is formed in a cylindrical shape, two air streams can easily form two vortexes while penetrating the inside of the main body 211 . However, the inside of the main body 211 is not limited thereto and may be formed in various other shapes such as an oval shape. The length and cross-sectional area of the main body 211 may be appropriately adjusted to treat the sewage in the treatment tank 10.

The inlet 212 is a part through which sewage in the treatment tank 10 flows into the main body 211 . As the sewage inside the main body 211 is discharged to the outside of the main body 211, the sewage received inside the treatment tank 10 outside the main body 211 flows into the inside of the main body 211. In this way, the inside of the main body 211 The inflowing sewage is introduced through the inlet 212 . The inlet 212 may have various shapes through which sewage in the treatment tank 10 may flow into the main body 211 . For example, the inlet 212 is formed in the shape of a circular hole at the lower end of the cylindrical body 211, as shown in FIGS. 6 and 7, so that sewage inside the body 211 is removed from the body ( 211) As sewage is discharged to the outside through the upper discharge part 213, sewage from the lower outside of the main body 211 can be easily introduced into the main body 211. In this case, if the inlet 212 is arranged to be separated from the bottom of the treatment tank 10 by a predetermined distance, sewage from the lower exterior of the main body 211 can be smoothly introduced into the main body 211 .

The discharge part 213 is a part through which sewage inside the main body 211 is discharged to the outside of the main body 211 . The sewage introduced into the main body 211 is injected into the main body 211 and converted into two vortexes, and then converted into two vortexes by the two air discharged to the outside of the main body 211. The sewage discharged to the outside of the main body 211 is discharged through the discharge unit 213. The discharge unit 213 may be formed in various shapes through which sewage inside the main body 211 may be discharged to the outside of the main body 211 . For example, the discharge unit 213 is formed in a circular hole shape at the upper end of the cylindrical body 211, as illustratively shown in FIG. 7, so that it is injected into the body 211 in two to form two vortexes. After being converted, it can be easily discharged to the outside of the main body 211 by the air discharged to the outside of the main body 211 . In this case, the discharge unit 211 is arranged so as to be separated from the surface of the sewage received in the treatment tank 10 by a predetermined distance so that the sewage inside the main body 211 passes through the discharge unit 211 to the upper side of the main body 211. It can be smoothly discharged as sewage accommodated in the external treatment tank 10 .

The air inlet 220 is a part through which air introduced into the treatment tank 10 from the outside of the treatment tank 10 passes. Accordingly, air may be introduced into the vortex generator 200 inside the treatment tank 10 from the outside of the treatment tank 10 . The air inlet 220 is connected to an air supply source located outside the treatment tank 10 to receive air.

The air inlet 220 has a length and cross-sectional area that allows air to be introduced into the vortex generator 200 from an air supply source.

The air inlet 220 may extend from the air supply source to have various shapes. For example, the air inlet 220 is an extension extending to be located on the central axis of the chamber 210 along the central axis direction of the chamber 210, as exemplarily shown in FIGS. 5 and 6 ( 221) may be included. As a result, since the volume in the horizontal direction perpendicular to the central axis direction of the chamber 210 of the vortex generator 200 including the air inlet 220 can be miniaturized, the vortex including the air inlet 220 When the generator 200 is installed in the treatment tank 10, the vortex generator 200 is smoothly injected into the treatment tank 10 even through a small injection hole formed in the cover covering the upper part of the treatment tank 10. be able to install it.

The air inlet 220 has a branching part 222 through which air introduced through the extension part 221 is branched into the first air accelerating part 230 and the second air accelerating part 240 . The branching part 222 may be configured in various configurations such that air introduced through the extension part 221 is branched into the first air accelerating part 230 and the second air accelerating part 240 . For example, the branch 222 of the air inlet 220 may have a smaller cross-sectional area than the extension 221 of the air inlet 220, as exemplarily shown in FIGS. 5 and 6 . there is. When the air flowing through the extension part 221 of the air inlet 220 is branched into the first air accelerator part 230 and the second air accelerator part 240 via the branch part 222, the flow of air As the direction is changed, the flow rate of air can be reduced. The branching portion 222 having such a configuration can prevent the flow rate of air from being reduced. That is, since the branching part 222 has a smaller cross-sectional area than the flowing part 221, the flow rate of the air introduced from the flowing part 221 is increased while passing through the branching part 222, so that the first air accelerating part 230 ) and the second air accelerator 240, it is possible to prevent or reduce the flow rate of the air introduced from the flow unit 221 from being reduced.

The first air accelerator 230 is a part that accelerates and discharges the air branched from the air inlet 220 while flowing. The air branched from the air inlet 220 by the first air accelerator 230 and introduced is accelerated at high speed and supplied to the inside of the main body 211 of the chamber 210, thereby supplying air to the main body 211 of the chamber 210. ) is converted into a vortex having a high flow rate inside and discharged to the outside of the main body 211 of the chamber 210. The sewage received inside the main body 211 of the chamber 210 by the first air vortex having a high flow rate inside the main body 211 of the chamber 210 is converted into a first sewage vortex having a high flow rate, The air is discharged to the outside of the main body 211 of the chamber 210 through the discharge unit 213 at a high speed along with the air vortex. In this process, the first air vortex and the first sewage vortex prevent the flow velocity of the other side from being reduced by interaction and improve mixing with the other side by mutual close contact, so that the oxygen contained in the first air vortex flows into the first sewage It is smoothly supplied to the vortex. Furthermore, as the sewage accommodated inside the body 211 of the chamber 210 is discharged to the outside of the body 211 at high speed through the discharge unit 213, the sewage received in the treatment tank 10 outside the body 211 flows in. By flowing into the body 211 at high speed through the part 212, the sludge accumulated on the bottom of the treatment tank 10 flows. Therefore, the breeding and activity of aerobic bacteria included in the sewage in the treatment tank 10 is greatly increased, thereby significantly increasing the efficiency of sewage treatment.

The first air accelerating unit 230 may have various shapes in which the air diverted from the air inlet 220 is accelerated at a high speed while flowing and discharged. For example, the first air accelerator 230 may include a first end 231 , an accelerator 232 and a second end 233 .

The first end 231 is a portion where the first air accelerator 230 is connected to the air inlet 220 and air diverged from the air inlet 220 is introduced. The first end 231 may be integrally connected to the air inlet 220, but is not limited thereto and may be detachably connected to the air inlet 220 as needed.

The accelerator 232 is a part that accelerates the air introduced through the first end 231 while flowing. The accelerator 232 may be configured in various configurations to accelerate the air introduced through the first end 231 while flowing. For example, the accelerator 232 extends from the first end 231 and has a cross-sectional area smaller than the cross-sectional area of the air inlet 220, as shown in FIGS. Through the end portion 231, air diverted from the air inlet 220 having a larger cross-sectional area may increase the flow rate while passing through the accelerator 232 having a smaller cross-sectional area. Furthermore, the accelerator 232 gradually reduces the cross-sectional area from the first end 231 to the second end 232 so that the air inlet 220 has a larger cross-sectional area through the first end 231. The flow rate may be gradually increased while the air introduced from ) passes through the accelerator 232 having a gradually smaller cross-sectional area.

The accelerator 232 has a length and a cross-sectional area through which air introduced through the first end 231 can be accelerated while flowing.

As illustrated in FIGS. 5 and 6, the accelerator 132 is refracted from the air inlet 220 and extends in a direction crossing the central axis of the chamber 210 (232a). ), and a second accelerator 232b that is refracted from the first accelerator 232a and extends in a direction parallel to the central axis of the chamber 210 .

The first accelerator 232a is refracted from the air inlet 220 and extends in a direction crossing the central axis of the chamber 210, for example, in a first radial direction, and has a cross-sectional area of the air inlet 220. It may have a smaller cross-sectional area. Accordingly, the air branched from the air inlet 220 and introduced into the first accelerator 232a through the first end 231 and flowing in a radial direction with respect to the central axis of the chamber 210 has a smaller cross-sectional area. It is possible to increase the flow rate while passing through a passage having Furthermore, the first accelerator 232a has a cross-sectional area that gradually decreases as it extends from the first end 231, so that the flow rate of air introduced from the air inlet 220 through the first end 231 gradually decreases. can be made to increase.

The second acceleration unit 232b is refracted from the first acceleration unit 232a and extends in a direction along the central axis of the chamber 210, and has a cross-sectional area equal to or smaller than that of the first acceleration unit 232a. can be provided. As a result, the air that is refracted from the first accelerator 232a and flows into the second accelerator 232b and flows in the direction of the central axis of the chamber 210 passes through a passage having the same or smaller cross-sectional area, and the flow rate increases. can be maintained or increased. Furthermore, the cross-sectional area of the second accelerator 232b gradually decreases as it extends from the first accelerator 232a, thereby gradually increasing the flow rate of the air introduced from the first accelerator 232a. .

The second accelerator 232b may extend along the central axis of the chamber 210 to be adjacent to the outer surface of the main body 211 of the chamber 210 . As a result, since the volume in the horizontal direction perpendicular to the central axis direction of the chamber 210 of the vortex generator 200 including the second accelerator 232b can be miniaturized, the second accelerator 232b is included. When the vortex generator 200 is installed in the treatment tank 10, the vortex generator 200 is smoothly injected through the small injection hole formed in the cover covering the upper part of the treatment tank 10 to treat the treatment tank 10 It can be easily installed inside.

The second end 233 is a part that is connected to the first air blowing part 240 and discharges the air accelerated by the accelerating part 232 to the first air blowing part 240 . The second end 233 may be integrally connected to the first air blowing part 240, but is not limited thereto and may be detachably connected to the first air blowing part 240 as needed.

Air accelerated from the first air accelerator 230 is introduced into the first air injection unit 240 through one end connected to the second end 233 of the first air accelerator 230, and the chamber 210 Accelerated air is injected so that a first vortex turning along the inner surface of the body 211 of the chamber 210 is generated into the body 211 of the chamber 210 through the other end connected to the inside of the body 211 of the Part.

Accelerated air is injected into the body 211 of the chamber 210 by the first air blowing unit 240 so that a swirling vortex is generated along the inner surface of the body 211 of the chamber 210, so that the air is blown into the chamber ( Inside the main body 211 of the chamber 210, it is converted into a first air vortex having a high flow rate and discharged to the outside of the main body 211 of the chamber 210. The sewage received inside the main body 211 of the chamber 210 by the first air vortex having a high flow rate inside the main body 211 of the chamber 210 is converted into a first sewage vortex having a high flow rate, It is discharged to the outside of the main body 211 of the chamber 210 together with the air vortex. In this process, the first air vortex and the first sewage vortex prevent the flow velocity of the other side from being reduced by interaction and improve mixing with the other side by mutual close contact, so that the oxygen contained in the first air vortex flows into the first sewage It is smoothly supplied to the vortex.

The first air blowing unit 240 ejects accelerated air so that a swirling vortex is generated along the inner surface of the body 211 of the chamber 210 by the accelerated air introduced from the first air accelerating unit 230. It can have various shapes. For example, as illustrated in FIG. 7 , the first air blowing unit 240 directs the air to be injected in a direction crossing the central axis of the chamber 210 and tangential to the inner surface of the main body 211. It may be arranged to be sprayed along. As a result, the accelerated air injected along the tangential direction to the inner surface of the main body 211 minimizes deceleration due to collision with the inner surface of the main body 211 so that it can smoothly turn at high speed along the inner surface of the main body 211. do.

Furthermore, the first air blowing unit 240 may further accelerate the accelerated air introduced from the first air accelerating unit 230 by having a smaller cross-sectional area than that of the first air accelerating unit 230. there is. As a result, the air accelerated to have a higher flow rate than the air accelerated by the first air accelerator 230 is injected into the body 211 of the chamber 210, so that the air moves through the body 211 of the chamber 210. It is converted into a vortex having a higher velocity inside and discharged to the outside of the main body 211 of the chamber 210. The sewage received inside the main body 211 of the chamber 210 by the first air vortex having a higher flow rate inside the main body 211 of the chamber 210 is transferred to the first sewage vortex having a higher high speed flow rate. It is converted and discharged to the outside of the body 211 of the chamber 210 at a higher speed through the discharge part 213 together with the air vortex. In this process, the first air vortex and the first sewage vortex prevent the flow velocity of the other side from being reduced by a greater interaction and further improve mixing with the other side by a greater close contact with each other, so that the first air vortex included in the first air vortex Oxygen is more smoothly supplied to the first sewage vortex. Furthermore, as the sewage received inside the main body 211 of the chamber 210 is discharged to the outside of the main body 211 at a higher speed through the discharge part 213, the inside of the main body 211 is further passed through the inlet part 212. As the sewage accommodated in the treatment tank 10 outside the main body 211 flows in at high speed, the sewage contained in the treatment tank 10 is more smoothly converted into a vortex flow, and the sludge accumulated at the bottom of the treatment tank 10 flows more It becomes. Therefore, the breeding and activity of aerobic bacteria included in the sewage in the treatment tank 10 are further greatly increased, thereby further significantly increasing the efficiency of sewage treatment.

Furthermore, the cross-sectional area of the first air blowing unit 240 gradually decreases from the end connected to the first air accelerating unit 230 to the end blowing air into the main body 211 of the chamber 210. The flow rate of the injected air may be gradually increased.

The first air blowing unit 240 rotates along the inner surface of the main body 211 of the chamber 210 as the air introduced from the first air accelerating unit 230 is sprayed into the main body 211 of the chamber 210. It has a length and cross-sectional area at which vortices can be generated.

The first air blowing unit 240 may extend from the first air accelerating unit 230 to have various shapes. For example, the first air blowing part 240 is bent from the first air accelerating part 230 and extends toward the inside of the main body 211 of the chamber 210, as shown in FIGS. 5 and 6 by way of example. it could be Here, the direction in which the first air blowing part 240 extends toward the inside of the main body 211 of the chamber 210 is the direction in which the air injected into the main body 211 crosses the central axis of the chamber 210 and the main body. (211) may be a direction such that it is sprayed along a direction tangential to the inner surface.

The first air blowing part 240 penetrates the outer surface of the chamber 210 so that an air blowing end may protrude into the main body 211 of the chamber 210 . However, the air blowing end of the first air blowing unit 240 is not limited thereto and may not protrude into the main body 211 of the chamber 210 and may coincide with a hole formed on a side surface of the main body 211 . The air blowing end of the first air jetting unit 240 is a predetermined distance from the inlet 212 of the main body 211 of the chamber 210 toward at least the center of the main body 211, for example, the jetted air flows in. It is preferable to be spaced apart by a distance enough to move toward the central portion of the main body 211 without leaking into the portion 212 .

The second air accelerator 250 is a part that accelerates and discharges air branched from the air inlet 220 in a direction different from that of the first air accelerator 230 while flowing. Air branched from the air inlet 220 by the second air accelerator 250 and introduced is accelerated at high speed and supplied into the main body 211 of the chamber 210, thereby supplying air to the main body 211 of the chamber 210. ) is converted into a second air vortex having a high flow rate inside and discharged to the outside of the main body 211 of the chamber 210. The sewage received inside the main body 211 of the chamber 210 is converted into a second sewage vortex having a high flow rate by the second air vortex having a high flow rate inside the main body 211 of the chamber 210. The air is discharged to the outside of the main body 211 of the chamber 210 through the discharge unit 213 at a high speed along with the air vortex. In this process, the second air vortex and the second sewage vortex prevent the flow velocity of the other side from being reduced by interaction and improve mixing with the other side by mutual close contact, so that the oxygen contained in the second air vortex flows into the second sewage It is smoothly supplied to the vortex. Furthermore, as the sewage accommodated inside the body 211 of the chamber 210 is discharged to the outside of the body 211 at high speed through the discharge unit 213, the sewage received in the treatment tank 10 outside the body 211 flows in. By flowing into the body 211 at high speed through the part 212, the sludge accumulated on the bottom of the treatment tank 10 flows. Therefore, the breeding and activity of aerobic bacteria included in the sewage in the treatment tank 10 is greatly increased, thereby significantly increasing the efficiency of sewage treatment.

The second air accelerator 250 may have various shapes in which the air diverted from the air inlet 220 is accelerated at a high speed while flowing and discharged. For example, the second air accelerator 250 may include a first end 251 , an accelerator 252 and a second end 253 .

The first end 251 is a portion where the second air accelerator 250 is connected to the air inlet 220 and air diverged from the air inlet 220 is introduced. The first end 251 may be integrally connected to the air inlet 220, but is not limited thereto and may be detachably connected to the air inlet 220 as needed.

The accelerator 252 is a part that accelerates the air introduced through the first end 251 while flowing. The accelerator 252 may be configured in various configurations to accelerate the air introduced through the first end 251 while flowing. For example, the accelerator 252 extends from the first end 251 and has a cross-sectional area smaller than the cross-sectional area of the air inlet 220, as shown in FIGS. Through the end portion 251, air diverted from the air inlet 220 having a larger cross-sectional area may increase the flow rate while passing through the accelerator 252 having a smaller cross-sectional area. Furthermore, the accelerator 252 gradually reduces the cross-sectional area from the first end 251 to the second end 252, so that the air inlet 220 has a larger cross-sectional area through the first end 251. The flow rate may be gradually increased while the air introduced from ) passes through the accelerator 252 having a gradually smaller cross-sectional area.

The acceleration unit 252 has a length and a cross-sectional area through which air introduced through the first end 251 can be accelerated while flowing.

As illustrated in FIGS. 5 and 6 , the accelerator 252 is refracted from the air inlet 220 and extends in a direction crossing the central axis of the chamber 210 ( 252a ). ), and a second accelerator 252b that is refracted from the first accelerator 252a and extends in a direction parallel to the central axis of the chamber 210 .

The first accelerator 252a is refracted from the air inlet 220 and intersects the central axis of the chamber 210, for example, the first accelerator 232a of the first air accelerator 230 and It extends in the opposite second radial direction and may have a smaller cross-sectional area than the cross-sectional area of the air inlet 220 . Accordingly, the air branched from the air inlet 220 and introduced into the first accelerator 252a through the first end 231 and flowing in a radial direction with respect to the central axis of the chamber 210 has a smaller cross-sectional area. It is possible to increase the flow rate while passing through a passage having Furthermore, the first accelerator 252a has a cross-sectional area that gradually decreases as it extends from the first end 251, so that the flow rate of air introduced from the air inlet 220 through the first end 251 gradually decreases. can be made to increase.

Meanwhile, the sum of the cross-sectional area of the first accelerator 232a of the first air accelerator 230 and the cross-sectional area of the first accelerator 252a of the second air accelerator 250 is the air inlet 220 may be smaller than the cross-sectional area of Accordingly, the flow rate of the air flowing through the cross section of the first accelerator 232a of the first air accelerator 230 and the air flowing through the cross section of the first accelerator 252a of the second air accelerator 250 The flow rate of may be greater than the flow rate of air flowing through the cross section of the air inlet 220, respectively.

The second acceleration unit 252b is refracted from the first acceleration unit 252a and extends in a direction along the central axis of the chamber 210, and has a cross-sectional area equal to or smaller than that of the first acceleration unit 252a. can be provided. As a result, the air that is refracted from the first acceleration unit 252a and flows into the second acceleration unit 252b and flows in the direction of the central axis of the chamber 210 passes through a passage having the same or smaller cross-sectional area, and the flow rate increases. can be maintained or increased. Furthermore, the cross-sectional area of the second accelerator 252b gradually decreases as it extends from the first accelerator 252a, thereby gradually increasing the flow rate of the air introduced from the first accelerator 252a. .

The second accelerator 252b may extend along the central axis of the chamber 210 to be adjacent to the outer surface of the main body 211 of the chamber 210 . As a result, since the volume in the horizontal direction perpendicular to the central axis direction of the chamber 210 of the vortex generator 200 including the second accelerator 252b can be miniaturized, the second accelerator 252b is included. In installing the vortex generator 200 in the treatment tank 10, the vortex generator 200 can be opened and closed by the door 12 formed on the cover covering the upper part of the treatment tank 10. ) can be smoothly injected and can be easily installed in the treatment tank 10.

Meanwhile, the sum of the cross-sectional area of the second accelerator 232b of the first air accelerator 230 and the cross-sectional area of the second accelerator 252b of the second air accelerator 250 is the air inlet 220 may be smaller than the cross-sectional area of Accordingly, the flow velocity of air flowing through the cross section of the second accelerator part 232b of the first air accelerator part 230 and the air flowing through the cross section of the second accelerator part 252b of the second air accelerator part 250 The flow rate of may be greater than the flow rate of air flowing through the cross section of the air inlet 220, respectively.

The second end 253 is a part that is connected to the second air blowing part 260 and discharges the air accelerated by the accelerating part 252 to the second air blowing part 260 . The second end 253 may be integrally connected to the second air blowing part 260, but is not limited thereto and may be detachably connected to the second air blowing part 260 as needed.

The second air injection unit 260 introduces accelerated air from the second air acceleration unit 250 through one end connected to the second end 253 of the second air acceleration unit 250, and the chamber 210 Accelerated air is injected to generate a second vortex turning along the inner surface of the body 211 of the chamber 210 into the body 211 of the chamber 210 through the other end connected to the inside of the body 211 of the Part.

Accelerated air is injected into the main body 211 of the chamber 210 by the second air blowing unit 260 so that a swirling vortex is generated along the inner surface of the main body 211 of the chamber 210, so that the air is blown into the chamber ( Inside the body 211 of the chamber 210, it is converted into a second air vortex having a high flow rate and discharged to the outside of the body 211 of the chamber 210. The sewage received inside the main body 211 of the chamber 210 is converted into a second sewage vortex having a high flow rate by the second air vortex having a high flow rate inside the main body 211 of the chamber 210. It is discharged to the outside of the main body 211 of the chamber 210 together with the air vortex. In this process, the second air vortex and the second sewage vortex prevent the flow velocity of the other side from being reduced by interaction and improve mixing with the other side by mutual close contact, so that the oxygen contained in the second air vortex flows into the second sewage It is smoothly supplied to the vortex.

The second air blowing unit 260 sprays accelerated air so that a swirling vortex is generated along the inner surface of the main body 211 of the chamber 210 by the accelerated air introduced from the second air accelerating unit 250. It can have various shapes. For example, the second air blowing unit 260, as illustratively shown in FIG. 7, the direction in which the air to be injected crosses the central axis of the chamber 210 and is tangential to the inner surface of the main body 211 It may be arranged to be sprayed along. As a result, the accelerated air injected along the tangential direction to the inner surface of the main body 211 minimizes deceleration due to collision with the inner surface of the main body 211 so that it can smoothly turn at high speed along the inner surface of the main body 211. do.

Furthermore, the second air blowing unit 260 may further accelerate the accelerated air introduced from the second air accelerating unit 250 by having a smaller cross-sectional area than that of the second air accelerating unit 250. there is. As a result, the air accelerated to have a higher flow rate than the air accelerated by the second air accelerator 250 is injected into the main body 211 of the chamber 210, so that the air flows through the main body 211 of the chamber 210. It is converted into a vortex having a higher velocity inside and discharged to the outside of the main body 211 of the chamber 210. The sewage received inside the body 211 of the chamber 210 by the second air vortex having a higher speed flow rate inside the main body 211 of the chamber 210 is transferred to the second sewage vortex having a higher speed flow rate It is converted and discharged to the outside of the body 211 of the chamber 210 at a higher speed through the discharge part 213 together with the air vortex. In this process, the second air vortex and the second sewage vortex prevent the flow velocity of the other side from being reduced by a larger interaction and further improve mixing with the other side by a greater close contact with each other. Oxygen is more smoothly supplied to the second sewage vortex. Furthermore, as the sewage received inside the main body 211 of the chamber 210 is discharged to the outside of the main body 211 at a higher speed through the discharge part 213, the inside of the main body 211 is further passed through the inlet part 212. As the sewage accommodated in the treatment tank 10 outside the main body 211 flows in at high speed, the sewage contained in the treatment tank 10 is more smoothly converted into a vortex flow, and the sludge accumulated at the bottom of the treatment tank 10 flows more It becomes. Therefore, the breeding and activity of aerobic bacteria included in the sewage in the treatment tank 10 are further greatly increased, thereby further significantly increasing the efficiency of sewage treatment.

Furthermore, the second air blowing unit 260 gradually reduces its cross-sectional area from the end connected to the second air accelerating unit 250 to the end blowing air into the main body 211 of the chamber 210. The flow rate of the injected air may be gradually increased.

Meanwhile, the sum of the cross-sectional area of the first air blowing part 240 and the cross-sectional area of the second air blowing part 260 may be smaller than the cross-sectional area of the air inlet 220 . Accordingly, the flow rate of the air flowing through the cross section of the first air blowing part 240 and the flow rate of the air flowing through the cross section of the second air blowing part 260 are respectively the air flowing through the cross section of the air inlet 220. can be greater than the flow rate of

The second air blowing unit 260 rotates along the inner surface of the main body 211 of the chamber 210 as the air introduced from the second air accelerating unit 250 is injected into the main body 211 of the chamber 210. It has a length and cross-sectional area at which vortices can be generated.

The second air blowing unit 260 may extend from the second air accelerating unit 250 to have various shapes. For example, the second air blowing unit 260 is bent from the second air accelerating unit 250 and extends toward the inside of the main body 211 of the chamber 210, as shown in FIGS. 5 and 6 by way of example. it could be Here, the direction in which the second air blowing unit 260 extends toward the inside of the main body 211 of the chamber 210 is the direction in which the air injected into the main body 211 crosses the central axis of the chamber 210 and the main body. (211) may be a direction such that it is sprayed along a direction tangential to the inner surface.

The second air blowing unit 260 penetrates the outer surface of the chamber 210 so that an air blowing end may protrude into the main body 211 of the chamber 210 . However, the air blowing end of the second air blowing unit 260 is not limited thereto and may not protrude into the main body 211 of the chamber 210 and may coincide with a hole formed on a side surface of the main body 211 . The air blowing end of the second air jetting unit 260 is a predetermined distance from the inlet 212 of the main body 211 of the chamber 210 toward at least the center of the main body 211, for example, the jetted air flows in. It is preferable to be spaced apart by a distance enough to move toward the central portion of the main body 211 without leaking into the portion 212 .

The microbubble generating unit 270 is a part that generates microbubbles from the first air vortex and the second air vortex turning along the inner surface of the main body 211 of the chamber 210 . As a result, the first microbubbles and the second microbubbles generated from the first air vortex and the second air vortex turning along the inner surface of the main body 211 of the chamber 210 are inside the main body 211 of the chamber 210 Oxygen contained in the air of the first microbubbles and the second microbubbles can be smoothly transferred to the sewage by moving in close contact with the received sewage as well as the sewage converted into vortex inside the main body 211, and thus to the sewage The propagation and activity of aerobic bacteria contained in the wastewater treatment efficiency is greatly increased.

The microbubble generating unit 270 may be configured in various configurations to generate microbubbles from air vortexes turning along the inner surface of the main body 211 of the chamber 210 . For example, as illustrated in FIGS. 6 and 7 , the microbubble generator 270 includes a plurality of protrusions protruding from the inner surface of the main body 211 toward the central axis of the main body 211 of the chamber 210. can be made with Here, it is preferable that the plurality of protrusions are arranged on a path along which the first air vortex and the second air vortex turn along the inner surface of the main body 211 of the chamber 210 . Here, the degree of protrusion of the plurality of protrusions can be made in various ways. For example, as shown in FIG. Protrusions arranged on the same and different cross sections may have different degrees of protrusion.

The support part 280 supports the chamber 210 so that the chamber 210 is separated from the bottom of the treatment tank 10 by a predetermined distance. As a result, the vortex generator 200 including the chamber 210 can be stably installed in the treatment tank 10, and through the inlet 212 formed at the lower end of the main body 211 of the chamber 210 Sewage may be smoothly introduced into the body 211 from the lower outside of the body 211 .

The support part 280 may have various configurations capable of supporting the chamber 210 so that the chamber 210 is separated from the bottom of the treatment tank 10 by a predetermined distance. For example, as shown in FIGS. 5 and 6, the upper part of the support part 280 is coupled to the lower outer surface of the main body 211 of the chamber 210 and the lower part is the main body of the chamber 210. (211) may be formed of a plurality of support bars extending downward from the lower end of the upper side surface.

It can be stably fixed in place. Therefore, the high-efficiency vortex generator 200 for a water treatment system according to the present embodiment can be easily installed or replaced without the need to remove the sewage while the sewage is accommodated in the treatment tank 10.

At this time, the sewage received inside the main body 211 of the chamber 210 by the second air vortex having a high flow rate inside the main body 211 of the chamber 210 is converted into a second sewage vortex having a high flow rate, 2 is discharged to the outside of the body 211 of the chamber 210 at high speed through the discharge unit 213 together with the air vortex.

In this process, the high-speed first air vortex and the second air vortex and the high-speed first sewage vortex and the second sewage vortex interact to prevent the flow velocity of the other party from being reduced and to be mixed with the other party by mutual close contact. By improving it, the oxygen contained in the air vortex is smoothly supplied to the sewage vortex. Furthermore, as the sewage received inside the main body 211 of the chamber 210 is discharged to the outside of the main body 211 at high speed through the discharge part 213, the main body 211 enters the main body 211 at high speed through the inlet part 212. (211) Sewage contained in the external treatment tank 10 flows in, and as this process is repeated, the sewage contained in the treatment tank 10 is converted into a vortex passing through the inside of the main body 211 of the chamber 210. At this time, sludge accumulated on the bottom of the treatment tank 10 flows while the sewage received in the treatment tank 10 outside the main body 211 flows into the main body 211 at high speed through the inlet 212 . Therefore, the breeding and activity of aerobic bacteria included in the sewage in the treatment tank 10 is greatly increased, thereby significantly increasing the efficiency of sewage treatment.
