Description

[0001] The present invention relates to a system and method for improving turbidity,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for improving turbidity, and more particularly, to a turbidity improvement system capable of eliminating problems caused by turbidity in water as the turbidity of sea water is rapidly improved and re- And methods.

In general, marine structures such as quay walls, caissons, and piers are composed of reinforcing bars and concrete, and the strength of the structure is lowered due to the erosion, and excessive stress is generated in the direction of the vertical axis of the structure due to the gravity of the marine structure itself , Detachment and loss of concrete occur, and corrosion of the reinforcing bars is exposed to water due to detachment of the concrete in the offshore structure.

In order to prevent this, it is necessary to quickly and accurately diagnose the abnormality of the offshore structures and to perform proper repair and reinforcement works to prevent the collapse of the offshore structure due to abrasion and erosion due to flow velocity and vortex. It is necessary.

Meanwhile, as a method for diagnosing an offshore structure, there has been proposed a method for detecting the degree of erosion and damage of the offshore structure by injecting a diver underwater and performing underwater photographing while swimming around the offshore structure. However, The abrasion and erosion sites of the offshore structures can not be accurately displayed on the drawings and there is a cumbersome problem that the divers have to submerge in the water again in order to grasp detailed abnormal positions through the experts.

In order to solve the above problems, various underwater diagnostic devices have been proposed recently. Korean Patent Laid-Open Publication No. 10-2012-80413 discloses an underwater photographing apparatus capable of moving in a vertical direction in water and stably photographing an underwater image without fluctuation in the flow of algae. However, since such an underwater photographing apparatus is configured to be guided only by a guide member provided with a photographing apparatus vertically, it is difficult to obtain a clean image in an underwater environment with high turbidity.

Korean Utility Model Registration No. 20-0364665 discloses a marine structure safety inspection imaging system in which a vertical rail is provided on a structure and the imaging device is guided to the vertical rail. In such a photographing system, since the photographing member is guided to the vertical rail, it is possible to perform close-up photographing, so that the safety inspection of the structure can be performed in a region where visual contamination is severe and visual inspection is impossible.

However, since the photographing system is configured to simply bring the photographing member close to the structure, it is possible to take close-up photographs, but only a part of the photographing has to be taken, so that it takes a lot of time to check the underwater photographing.

Meanwhile, such a conventional proposal provides a photographing system within the category of photographing a specific structure, but the existing system can not be used at all in the case of sinking a ship or searching for a large structure.

Therefore, there is a need for a technique capable of shooting in various environments in addition to a standardized structure in which difficulty in obtaining underwater photographing or underwater operation in water with high turbidity is difficult.

Hereinafter, preferred embodiments of the turbidity improving system and method according to the present invention will be described in detail with reference to the accompanying drawings.

The system and method for turbidity improvement according to the present invention are characterized by comprising a filtration unit for drawing suspended seawater (sea water) or a river having a relatively high turbidity of water contained in the water, A cooling unit for cooling the filtrate filtered by the suspended solids to a low temperature and converting the filtered water to the cooling water, and a supply unit for transmitting the cooling water cooled in the cooling unit to the arbitrary water space through the power of the pump.

A system and method for improving turbidity according to the present invention includes a seawater pump (100) for pumping seawater to a ship, a filtration unit (200) for filtering various types of suspended matters contained in seawater pumped from the seawater pump, A multi-channel cooling unit 300 for rapidly cooling the filtered seawater in the filtration unit, and a supply unit 400 for supplying the cooling water cooled in the cooling unit in water.

BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is an overall configuration diagram of a system and method for turbidity improvement according to the present invention. FIG. The system for improving turbidity according to the present invention mainly includes a seawater pump 100, a filtration unit 200, and a cooling unit located at sea level and includes a supply unit 400 for supplying seawater filtered and cooled in water ).

The seawater pump 100, the filtration unit 200, and the cooling unit 300 are installed on a ship constituting a system for improving turbidity. The system corresponds to a vessel equipped with a system for improving the turbidity, This is a structured ship in which the ship is dispatched to the site to improve the turbidity at the site at high speed.

The seawater pump 100 is a device for pumping seawater having a high turbidity into a ship. The system according to the present invention can be used in a marine environment where marine activities such as underwater shooting, underwater operation, lifesaving, Since it is very difficult to work, it is necessary to improve the turbidity and ensure the visibility.

To this end, the present invention is a system operated to improve turbidity after a turbidity-improving vessel is anchored to the shore. First, the on-site seawater is drawn up through a seawater pump to filter suspended matters contained in seawater in the filtration unit 200. Turbidity is very bad because seawater contains soil, microorganisms, and various floats. Accordingly, various foreign substances contained in the seawater are removed using the filtration unit.

The filtration unit 200 is a filtration apparatus provided with a filtration filter between a seawater inlet and an outlet. Generally, a fibrous system or a filtration body (filtration filter) 210 is applied to allow foreign matter to be caught by the filtration body And it is a matter of course that a variety of known materials can be used as the type of the filter body.

In the filtration unit 200 according to the present invention, foreign matter is filtered through various kinds of suspended matters contained in the seawater pumped by the seawater pump through the filtration unit.

Various kinds of foreign substances mixed in the seawater are cleanly filtered through the seawater pump and the filtration unit, and then rapidly cooled by the cooling unit 300.

The cooling unit 300 separates the seawater from the seawater by the seawater and the temperature of the seawater when the seawater is rapidly cooled to a low temperature and then supplied to the underwater.

The configuration of the cooling unit 300 constructed in accordance with the present invention will be described in detail below.

2 is a detailed view of the cooling section of the system for turbidity improvement according to the present invention. The cooling unit 300 includes a cooling tank 310 having a predetermined size for receiving cooling water, a cooler 320 for keeping the cooling water at a low temperature by being stored in the cooling tank, A cooling micro flow path 330 for rapidly cooling the cooling section, a control section for controlling the cooling section, and a flow rate valve 350 for controlling the cooling temperature according to the supply speed of the seawater.

The cooling unit 300 accommodates cooling water in a cooling tank and a cooling micro flow path 330 for passing the seawater filtered by the filtration unit is continuously arranged in a cooling tank for containing the cooling water. That is, the seawater passing through the cooling micro flow path is rapidly cooled and cooled by the cooling water.

The seawater filtered by the filtration unit is divided into micro flow channels having a bundle structure when the cooling micro flow channel is passed. When the cooling micro flow channels are completely passed through the micro flow channels, the seawater is concentrated into one flow channel again to supply low temperature cooled seawater. Accordingly, the cooling micro flow path 330 having a bundle structure is immersed in cooling water to receive cooling heat to receive cooling heat.

The cooling micro flow path according to the present invention is preferably composed of any one of a copper pipe, a stainless pipe, and a titanium pipe excellent in heat transfer.

In the present invention, the cooling temperature is controlled by controlling the flow rate of the cooling micro flow path by the flow rate valve 350 to control the cooling temperature of the seawater. The cooling water accommodated in the cooling tank maintains the ultra-low temperature state of -50 to -70, so that the sea water passing through the cooling micro flow path may be cooled beyond the low temperature state. Accordingly, in the present invention, when the seawater filtered by the pump is passed through the cooling micro-flow passage, the flow rate and the flow rate are controlled to cool the seawater while being supplied with the cooling heat.

Since the seawater cooled in the cooling unit 300 has a large temperature difference with the temperature of the seawater, when it is supplied into the water, the seawater can be separated by the temperature specific gravity difference to secure the view of the underwater.

Meanwhile, since the cooling unit 300 according to the present invention cools the seawater filtered through the micro flow path from a very low cooling fluid to a low temperature, the flowing sea water in the micro flow path can be frozen, and when the micro flow path is cooled, There arises a problem that it must be separated and checked.

Accordingly, in the present invention, a separate antifreeze supply part 500 is provided to prevent freezing of the microfluidic channel, and the antifreeze supply part supplies a certain amount of antifreeze from the upstream of the microfluidic channel according to the state of the cooling part. When the amount of discharge is smaller than the supply amount, it is perceived that the flow rate due to the freezing of the micro flow channel is not smooth, and a certain amount of antifreeze is supplied to prevent freezing.

At this time, the antifreeze supply part 500 recognizes that the microfluid is blocked by the freezing phenomenon when the discharge amount is sharply reduced considering the supply amount and the discharge amount of the filtration part, and opens the antifreeze valve to supply the antifreeze. Here, the antifreeze feeder may control the amount of the antifreeze supplied by detecting the amount of filtered water discharged.

3 is an overall flowchart of a system for turbidity improvement according to the present invention.

As shown in the figure, the seawater cooled and operated by the ship is quickly supplied to the water by the supply unit 400. The supply unit 400 is connected to the discharge line of the cooling unit and supplies the cooling seawater to the inside of the water. At this time, in order to supply the seawater to the water, a separate blocking wall is provided in the area of the water to supply the cooling seawater to the inside of the blocking wall can do. For example, in order to obtain an image of a pier in the water, the surrounding of the pier is enclosed by a barrier wall, and a supply section is installed in the barrier wall to supply cooling seawater so that a clean field of view can be secured have.

Another example is that in case of underwater shooting in a ship due to a ship accident, the supply part is connected to the inside of the ship without installing a separate blocking wall, and turbidity is improved by supplying the cooling seawater to the ship quickly. At this time, the distribution unit 410 is installed to efficiently supply the cooling seawater supplied by the supply unit.

The distribution unit 410 is installed in the water to uniformly distribute the cooling seawater supplied to the supply unit 400 according to the distribution number. The number of distributions of the distribution part can be designed and configured according to the underwater environment and conditions.

Therefore, the turbidity improvement system according to the present invention is a turbidity improvement system according to the present invention, in which high turbidity seawater is filtered and then a high-speed cooling system is applied so that it is separated from the underwater sea water by the temperature specific gravity, There is an advantage that it can be applied to various aspects.

4 is a flowchart illustrating an operation of the system for improving turbidity according to the present invention.

A method for improving turbidity according to the present invention will be described in detail with reference to FIG. First, after the turbidity improving vessel equipped with the filtration system and the cooling system is dispatched to the site requiring improvement of turbidity, the sea water pump 100 is used to raise the seawater to make the cooling water (S100). At this time, a large-sized tank structure capable of holding seawater may be placed on the ship, or if it is pumped by the seawater pump, it may be designed to be fed directly to the filtration unit 200 to be filtered.

After the seawater is drawn up through the seawater pump, various suspended matters contained in the seawater are primarily filtered through the filtration unit 200 (S200). At this time, the filtration unit can determine the degree of filtration according to need, such as two times of filtration, three times of filtration, and four times of filtration, and the number of times of operation of the filtration unit can be configured by selecting the degree of filtration according to the value of turbidity of the driver. It is possible to constitute a plurality of filtration sections to control the filtration speed and the filtration efficiency to be improved.

The seawater filtered through the filtration unit is transferred to the cooling unit 300 and is cooled. 2, the cooling unit can cool the seawater filtered by the cooling micro flow path at a high speed. The control unit 340 controls the flow rate valve 350 to control the cooling temperature of the seawater and the supply The speed is controlled.

The seawater cooled in the cooling unit 350 is configured to be rapidly supplied to the water through the supply unit 400. The cooled seawater may further include an additive for improving turbidity. In the present invention, when the cooling water cooled by the cooling unit is supplied into the water through the supply unit, it may further include a coagulant or a precipitant for immersing the floating material in the water. Here, the additive is separately stored in a separate tank, and the sea water cooled in the cooling unit is discharged from the additive tank and supplied together when the sea water is supplied to the supply unit.

At this time, since the temperature of the cooling seawater can be raised by the additive, it can be operated in the order that the additives are supplied immediately after being filtered in the filtration unit and then cooled through the cooling unit 300.

In addition, in the present invention, in order to improve the turbidity, turbidity is improved by the difference of the temperature specific gravity of the cooling sea water, additional materials such as sugar, calcium chloride and sodium sulfate are injected into the cooling sea water to separate the sea water As shown in FIG.

There is an advantage that more effective turbidity improvement can be achieved by additionally injecting not only the aforementioned additives but also a material controlling the specific gravity difference.

The cooled seawater containing the filtered seawater and various additives is rapidly supplied into the water through the supply unit 400. As described above, in the case of submerged ships or submerged structures, the cooling sea water supplied from the supply part is distributed by the distribution part and efficiently supplied, thereby providing the turbidity Can be improved.

At this time, a worker enters the inside of the water to select a supply part, a selection of a distribution part, and so on. In addition, a worker selects a supply part position and additionally arranges the distribution part 410 so that cooling water can be supplied efficiently .

The turbidity improving system according to the present invention configured as described above is particularly operated so that the seawater can be rapidly cooled in the seawater under high speed after filtration in the seabed underwater and can be rapidly supplied to the water. The cooling water supplied in the water has turbidity By separating from high water, underwater work can secure visibility in water such as underwater photographing, and there is an advantage that turbidity can be efficiently improved in various conditions of underwater work.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. On the contrary, those skilled in the art will appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims. And all such modifications and changes as fall within the scope of the present invention are therefore to be regarded as being within the scope of the present invention.
