Description

WATER TREATING APPARATUS OF RESERVOIR WATER IN THE RIVER}

TECHNICAL FIELD The present invention relates to a water storage apparatus in a river.

In the case of reservoirs with low or no flow rates, the proliferation of algae and the lack of dissolved oxygen due to the influx of nutrients are particularly problematic. For example, appeals to reservoirs, lakes, ponds, swamps, wetlands, etc., unlike rivers with high flow rates, cause overcrowding of algae and consequent eutrophication due to stagnation of reservoirs.

Eutrophication is a phenomenon that occurs when nutrients such as nitrogen (N) and phosphorus (P) accumulate in reservoirs (lakes, reservoirs, etc.). As these nutrients continue to enter the appeal and the appeal loses its self-cleaning ability, water pollution gradually occurs, which is further facilitated by the stratification of the reservoir. As a result, various algae will multiply in the appeal, and the degradation products of these algae will repeat the vicious cycle of nutrients of other algae.

3 is a schematic perspective view of a micro bubble generator (MBG) 100 according to one embodiment.

Referring to FIG. 3, the MBG 100 may be installed in the conduit 18, and may include an air injection tube 400, a blade unit 120, a chamber 130, and a driver 140.

The air injection pipe 400 is a circular pipe for injecting air to the chamber 130 side by an air compressor. In the illustrated embodiment, the air injection pipe 400 is in the shape of a hollow circular pipe and is installed to penetrate the chamber 130 and the connection portion 121. A bearing 111 is interposed between the air injection pipe 400 and the connection part 121, so that the rotation operation of the connection part 12 does not affect the air injection pipe 400.

In the present embodiment, the central axis of the air injection pipe 400 and the protrusion 131 of the chamber are aligned with each other.

The air injection pipe 400 has a shape of a pipe through which air provided from an air compressor flows, and the air flowing in the air injection pipe 400 is pressurized to move in the direction of the chamber 130.

The blade unit 120 is coupled to surround the outside of the air injection pipe 400 and is a member that rotates independently of the air injection pipe 400. The blade part 120 may include a connection part 121 and a plurality of blades 122. The connection part 121 is a cylindrical member surrounding the outside of the air injection pipe 400, and a plurality of blades 122 are connected to the connection part 122, which is a cylindrical member, along a side surface of the connection part 122 in a radial direction at regular intervals. Attached.

Each blade 122 extends in the radial direction at the connecting portion 121 and the blade 129 is suspended, so that the blade 122 rotates when the blade 129 is rotated by the flow rate.

One end of the blade 122 is attached to the connecting portion 121 and extends substantially horizontally in a radially outward direction therefrom, and is bent downward so that the other end thereof faces vertically downward.

Specifically, the blade 122 is a horizontal extension portion extending horizontally in the radial direction from the connecting portion 121 surrounding the air injection pipe 400, and bent downward at the end of the extension portion is directed vertically downward It includes a vertical downward portion, wherein the horizontal extension portion is positioned in parallel with a predetermined distance spaced apart from the upper surface of the chamber 130 to be described later, the vertical downward portion is positioned parallel to the side surface of the chamber 130.

The chamber 130 is a member rotatably coupled to the lower end of the air injection pipe 400, and may include a protrusion 131, a main body 132, and a filter 133.

The main body 132 of the chamber is hollow, and is a cylindrical member composed of an upper surface, a side surface, and a lower surface. The diameter of the chamber 130 is slightly smaller than the diameter of the blade portion 120. That is, when the chamber 130 is coupled to the rotational axis P1, a portion of the blade 122 facing downward is spaced apart from the side surface of the chamber 130 by a predetermined distance.

At the center of the upper surface of the chamber 130, the protrusion 131 is formed to protrude from the upper surface. The protrusion 131 has a vertical through hole formed therein, and the air injection pipe 400 penetrates the protrusion 131. A bearing is interposed between the air injection pipe 400 and the protrusion 131, so that the chamber 130 rotates around the air injection pipe 400.

A plurality of openings are formed in the side surface of the chamber 130 at predetermined intervals, and a filter 133 is attached to each opening. In a preferred embodiment, the filter 133 may be a porous sintered filter, and thus may become microbubbles when air passes through one side of the filter 133 to be discharged from the other side of the filter 133. The filter 133 may be made of a material (eg, stainless steel or resin) including a fine path through which air may pass.

The driving unit 140 is disposed below the chamber 130. The driving unit 140 includes a motor 142 and a drive shaft 141. One end of the drive shaft 141 is connected to the rotation shaft of the motor 142 and the other end is coupled to the center of the lower surface of the chamber 130. Thus, the chamber 130 is rotated by the motor 142.

4 is a cross-sectional view of a connection unit according to an embodiment of the present invention.

As shown in FIG. 4, a bearing 111 is interposed between the gas injection pipe 400 and the connection part 121 such that the rotation of the connection part 12 does not affect the gas injection pipe 400.

5 is a cross-sectional view of the chamber 130 according to one embodiment. Referring to FIG. 5, the protrusion 131 of the chamber 130 is coupled to the lower end of the air injection pipe 400 through a bearing 134. Since the chamber 130 is rotatably coupled with the air injection tube 400, the chamber 130 may rotate based on the air injection tube 400 by receiving the driving force from the drive shaft 141.

Meanwhile, air supplied from the air compressor is discharged from the lower end of the air injection pipe 400 to fill the inside of the main body 132 of the chamber 130. When the pressure of the air is higher than a predetermined level, the air is discharged to the outside (water in the river) through the filter 133. At this time, the air passing through the filter 133 is discharged into the water in the form of micro bubbles. Furthermore, since the chamber 130 is rotated in the direction opposite to the rotation direction of the blade, micro bubbles can be easily generated.

6 is a schematic side view of a state in which the above-described MBG 100 is disposed in the conduit 18 according to one embodiment.

Referring to FIG. 6, it can be seen that the air injection pipe 400 penetrates the connection part 121 and is connected to the chamber 130. The blade portion 120 is coupled to the connection portion 121, and the chamber 130 is rotatably coupled to the air injection pipe 400 below. The chamber 130 is driven by the motor 142 and may rotate independently of the rotational direction of the blade 122 (preferably in the opposite direction). In FIG. 6, for convenience of description, the blade 139 in FIG. 3 is omitted. As shown in FIG. 6, each blade 122 is positioned close to the filter 133 so that the bubbles exiting through the filter 133 may be generated by the blade 122 into further finer bubbles. will be.

7 is an enlarged view of a portion A in FIG. 6.

In the preferred embodiment, while the chamber 130 is rotated by the drive unit 140, the air in the chamber 130 is rotated under the pressure of the continuous air supply from the air inlet tube 400, and thus the filter 133. ) Is discharged into the water in the form of micro bubbles (MB). At this time, since the chamber 130 is being rotated, the microbubble may be broken by the flow of water around the moment it is discharged through the filter 133, so that the microbubbles may be decomposed into smaller sizes.

Since the side of the main body 132 of the chamber 130 and the vertically downward portion of the blade 122 are located adjacent to each other, the microbubble hits the blade 122 immediately after being discharged into water, Can be cut back. In this case, the larger the relative rotational speed of the chamber 130 and the blade 122, the finer the microbubble will be cut. That is, according to one embodiment, the relative rotation speed can be increased by rotating the chamber 130 in the opposite direction to the rotation direction of the blade 122.

The wing 129 is rotated by the flow of water, thereby causing the blade 122 to rotate. Referring to FIG. 3, the shape of the blade 129 is configured in a ladle shape (with recesses) such that the blade 122 is rotated in a specific direction (counterclockwise (ccw)). In this case, the power supply 7 of FIG. 1 controls the direction of the motor 142 so that the chamber 130 rotates clockwise (cw). That is, the power supply unit 7 of FIG. 1 controls the motor 142 so that the rotational direction of the chamber 130 is opposite to the rotational direction of the blade 122.
