본 발명은 담수를 순환시키는 염도차 발전 장치에 관한 것으로, 보다 상세하게는 발전 효율을 향상시키고 환경 오염을 방지하며 설치 장소의 제약을 완화할 수 있는 염도차 발전 장치에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a salinity difference generator for circulating fresh water, and more particularly, to a salinity difference generator capable of improving power generation efficiency, preventing environmental pollution, and alleviating restrictions on installation sites.

염도차 발전기술은 삼투막으로 분리된 모듈에 가압된 염수와 담수를 각각 주입하고, 삼투현상에 의해 증가된 기수로 터빈을 회전시켜 전력을 생산하는 발전기술이다. 보통 고농도 용액으로 해수를 이용하며, 전처리 과정을 거친 담수가 삼투압 차에 의해 삼투막을 통하여 해수로 투과되고, 이때 증가한 유량에 의해 형성된 수압으로 터빈을 회전시켜 에너지를 생산한다. 여기서 3.5% 해수는 15기압, 7% 농축수는 25∼30 기압이 최적조건이고, 담수측 압력은 염수측 압력의 1/2이 효과적이다. 염도차 발전기술의 상업화를 위해서 해결되어야 과제로 막면적당 동력 밀도 향상, 막 가격의 하락, 에너지 소비율 향상이 있다.The salinity power generation technology is a power generation technology that injects pressurized brine and fresh water into a module separated by an osmosis membrane, and rotates the turbine with an increased nose by osmosis. Usually, seawater is used as a high concentration solution, and the pretreated fresh water is permeated to the seawater through the osmotic membrane by osmotic pressure, and the turbine is rotated by the water pressure formed by the increased flow to produce energy. Here, 3.5% seawater is 15 atmospheric pressure, 7% concentrated water is 25 ~ 30 atmospheric pressure, and freshwater pressure is 1/2 of brine pressure. As a commercialization of salinity generation technology, there are problems to be solved, such as improvement of power density per membrane, reduction of membrane price, and improvement of energy consumption rate.

또한 상기와 같은 염도차 발전을 위해서는 염수와 담수가 계속적으로 공급되어야 하므로 염도차 발전 시설의 설치 장소는 해수와 담수를 동시에 확보할 수 있는 지리적 장소로 제약된다는 문제가 있으며, 염수와 담수가 섞여서 만들어지는 기수가 터빈을 통과한 뒤 외부로 배출되므로 환경에 미치는 악영향이 있을 수 있다는 우려가 있다.
In addition, since salinity and fresh water must be continuously supplied for the above-mentioned salinity difference generation, there is a problem that the installation place of the salinity difference generation facility is limited to a geographical place where seawater and fresh water can be secured at the same time. There is a concern that there may be an adverse effect on the environment because the nose nose is discharged to the outside after passing through the turbine.

In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

도 1은 본 발명의 일 실시예에 따른 담수를 순환시키는 염도차 발전 장치의 개략적인 구성도이다. 도 1에 도시된 바와 같이 본 발명의 담수를 순환시키는 염도차 발전 장치는 염수조(100), 담수조(200), 삼투막(300), 역삼투부(400), 터빈(600)을 포함하여 이루어질 수 있다.1 is a schematic block diagram of a salinity difference generator for circulating fresh water according to an embodiment of the present invention. As shown in FIG. 1, the salinity generating device for circulating fresh water according to the present invention includes a salt water tank 100, a water tank 200, an osmosis membrane 300, a reverse osmosis unit 400, and a turbine 600 .

담수조(200)는 담수를 저장한다. 염수조(100)는 염수를 저장하고 삼투막(300)을 사이에 두고 담수조(200)에 접하며, 삼투막(300)을 통과하여 침투하는 담수에 의하여 발생하는 삼투압에 의하여, 저장된 염수를 기수로 변화시켜 분사한다.The water tank 200 stores fresh water. The brine tank 100 stores brine and contacts the fresh water tank 200 through the osmosis membrane 300. By the osmotic pressure generated by the permeating water passing through the osmosis membrane 300, Change and spray.

이 때 염수는 해수 뿐 아니라, 염화나트륨 용액 및 탄산수소나트륨 용액 등 담수와의 염도차에 의하여 삼투압을 발생시킬 수 있는 다양한 용액일 수 있다.In this case, the brine may be various solutions capable of generating osmotic pressure by the difference in salinity between fresh water and sodium chloride solution and sodium bicarbonate solution as well as seawater.

역삼투부(400)는 분사된 기수를 역삼투막(500)에 통과시켜 통과한 담수를 담수조(200)로, 통과하지 못한 염수를 염수조(100)로 각각 순환시킨다. 이 때 삼투막(300)이 발생시키는 삼투압이 역삼투막(500)에 의하여 발생하는 역삼투압보다 높아야 분사된 기수가 역삼투막(500)에서 담수와 염수로 분리되어 각각 순환될 수 있다.The reverse osmosis part (400) circulates the jetted water through the reverse osmosis membrane (500) to the fresh water tank (200) and the brine that has not passed through the salt water bath (100). At this time, if the osmotic pressure generated by the osmotic membrane 300 is higher than the reverse osmosis pressure generated by the reverse osmosis membrane 500, the injected nuclides may be separated from the reverse osmosis membrane 500 into fresh water and salt water and circulated.

일반적으로 염도차 발전기에서는 염수가 끊임없이 공급되어 삼투막에 의하여 담수로 섞여들어감으로써 발생하는 삼투압에 의하여 터빈(600)을 작동시키며 결과적으로 발생한 기수는 외부로 배출되게 된다. 따라서 염도차 발전기에서는 염수와 담수가 계속적으로 공급되어야 하므로 염수와 담수를 동시에 확보할 수 있는 장소로 발전 설비의 설치 위치가 제약된다. 또한 염수와 담수가 섞인 기수가 외부로 배출됨으로써 발생할 수 있는 환경에의 악영향이 우려되고 있다.Generally, in the salinity generator, salt water is continuously supplied and mixed with fresh water by an osmosis membrane, thereby operating the turbine 600 by the osmotic pressure generated and the resulting nose is discharged to the outside. Therefore, saltwater and fresh water must be continuously supplied to the salinity generators, and therefore, installation sites of the power generation facilities are restricted because they can secure both brine and fresh water. In addition, there is a concern about the adverse effect on the environment that may occur due to the discharge of the water containing the brine and the fresh water.

반면, 본 발명에 의하면 기수가 역삼투부(400)에 의하여 담수와 염수로 다시 분리되어 각각 순환되므로, 외부로부터 공급되어야 하는 담수와 염수의 양이 감소하므로, 같은 양의 염수 및 담수에 의하여 발전할 수 있는 효율이 향상되며, 또한 담수와 염수를 계속적으로 공급하여야 할 필요도 감소하므로, 담수와 염수를 주기적으로 공급하는 등의 수단으로 발전 설비의 설치 위치상의 제약을 감소시킬 수 있다.On the other hand, according to the present invention, since the nodal water is separately separated into fresh water and brine by the reverse osmosis part (400) and circulated separately, the amount of fresh water and brine to be supplied from outside is reduced, And the need to continuously supply fresh water and brine is also reduced. Therefore, restrictions on the installation position of the power generation facility can be reduced by means such as supplying fresh water and brine periodically.

터빈(600)은 역삼투부(400)가 역삼투막(500)에 통과시켜 순환시키는 담수에 의하여 동작하여 전력을 발전한다. 이 때, 염수조(100)는 외부에서 염수를 공급받을 수 있고, 담수조(200)는 외부에서 담수를 공급받을 수 있으며, 역삼투부(400)는 기수를 외부로 배출할 수 있다.The turbine 600 is operated by fresh water circulated through the reverse osmosis membrane (500) by the reverse osmosis part (400) to generate electric power. At this time, the brine tank 100 can receive the brine from the outside, the fresh water tank 200 can receive the fresh water from the outside, and the reverse osmosis part 400 can discharge the nose to the outside.

또한 담수조(200)는 수직 방향으로 기수를 분사하고, 역삼투부(400)는 역삼투막(500)을 통과한 담수 및 역삼투막(500)을 통과하지 않은 염수 중 적어도 하나를 담수조(200)로 낙하시키며, 터빈(600)은 담수조(200)로 낙하하는 담수 및 염수 중 적어도 하나에 의하여 동작할 수 있다. 즉, 역삼투부(400)가 도 1에 도시된 바와 같이 염수조(100)의 상부에 위치할 수 있으며, 삼투막(300)을 담수가 통과하여 발생한 삼투압으로 기수를 수직 방향으로 분사시켜 역삼투부(400)에 도달하게 할 수 있다.The reverse osmosis membrane 400 drops at least one of the fresh water that has passed through the reverse osmosis membrane 500 and the salt water that has not passed through the reverse osmosis membrane 500 into the water tank 200, The turbine 600 may be operated by at least one of fresh water and salt water falling into the water tank 200. That is, the reverse osmosis part 400 may be positioned above the saltwater bath 100 as shown in FIG. 1, and the osmosis membrane 300 may be sprayed in the vertical direction by the osmotic pressure generated by the fresh water passing through the osmosis membrane 300, (400).

또한 본 발명의 일 실시예에 따른 염도차 발전 장치의 담수조, 염수조 및 삼투막을 도시한 도면인 도 2를 참조하면, 염수조(100)는 원통형을 취하고, 담수조(200)는 염수조(100)를 둘러싸는 형태로 담수를 저장할 수 있으며, 담수조(200)와 염수조(100)가 서로 접하는 원통형 경계 전체가 삼투막(300)을 형성할 수 있다.2, which is a view showing a fresh water tank, a salt water tank and an osmosis membrane of a salinity difference generator according to an embodiment of the present invention, a salt water tank 100 takes a cylindrical shape, a water tank 200 has a salt water tank 100 And the entirety of the cylindrical boundary where the water tank 200 and the salt water tank 100 are in contact with each other can form the osmosis membrane 300.

이 경우, 발전 설비의 설치 공간에 비하여 가장 넓은 면적의 삼투막(300)을 형성할 수 있으므로, 같은 발전 효율을 갖는 발전 장치를 설치하기 위하여 필요한 공간을 절감할 수 있다.In this case, since the osmosis membrane 300 having the widest area compared to the installation space of the power generation facility can be formed, a space required for installing the power generation device having the same power generation efficiency can be saved.

또한 이 때, 수직 방향으로 기수를 분사하여, 분사된 기수 및 기수로부터 역삼투막(500)을 통과한 담수에 저장되는 위치에너지를 이용하여 담수를 담수조(200)로 낙하시키면서 터빈을 동작시킴으로써, 대형의 염수조(100) 및 담수조(200)를 사용하여야 하는 염도차 발전기에 있어서, 터빈이 설치되는 위치를 수직으로 배치하여 발전 시설이 설치되는 데에 필요한 공간을 절감할 수 있으며, 이에 따라 발전 장치의 설치 장소의 제약을 완화할 수 있다.At this time, by driving the turbine while jetting radial water in the vertical direction and dropping the fresh water into the water tank 200 using the potential energy stored in the fresh water passing through the reverse osmosis membrane 500 from the radiated water and the radiated water, In the salinity generator for which the salt water tank 100 and the water tank 200 are to be used, the space required for installing the power generation facility can be reduced by vertically arranging the turbine installation position, The restriction of the installation place can be relaxed.

도 3은 본 발명의 다른 실시예에 따른 염도차 발전 장치의 개략적인 구성도이다. 도 3에 도시된 바와 같이, 담수조(200)의 바닥은 염수조(100)와 접하는 면을 향하여 하강하도록 경사질 수 있다.3 is a schematic configuration diagram of a salinity difference generation device according to another embodiment of the present invention. As shown in FIG. 3, the bottom of the water tank 200 may be inclined so as to descend toward the side in contact with the salt water tank 100.

이렇게 담수조(200)의 바닥을 경사지게 구성함으로써 담수조(200)로부터 삼투막(300)을 통과하여 염수조(100)로 가해지는 삼투압에 담수조(200)에 저장된 담수의 무게에 의해서 가해지는 압력을 더하여 염수조(100)가 분사하는 기수의 압력을 증가시킬 수 있다. The bottom of the water tank 200 is inclined so that the pressure applied by the weight of the fresh water stored in the water tank 200 is added to the osmotic pressure applied to the salt water tank 100 through the osmotic membrane 300 from the water tank 200 The pressure of the radiant water sprayed by the salt water tank 100 can be increased.

따라서, 역삼투부(400)가 염수 및 기수를 터빈(600)을 향하여 순환시킬 때, 염수 및 기수에 가해지는 압력 역시 증가할 수 있으므로 발전 효율이 더욱 향상될 수 있다.Therefore, when the reverse osmosis part 400 circulates the brine and the nose toward the turbine 600, the pressure applied to the brine and the nose can also increase, so that the power generation efficiency can be further improved.

이상 살펴본 바와 같이 본 발명에 따르면, 담수를 삼투막에 통과시켜 압력을 발생시키고 염수와 담수와 섞여 생성된 기수를 다시 역삼투막을 통과시켜 담수를 제거함으로써, 염수 및 담수를 순환시켜 재사용할 수 있으므로, 염수의 공급을 절감하고 담수와 섞인 염수의 발생을 방지하여 환경 오염을 방지할 수 있고, 같은 양의 염수로 발전할 경우 발전 효율을 향상시킬 수 있으며, 삼투막을 통과하여 발생하는 압력을 수직 방향으로 전달함으로써 발전 장치의 설치 장소의 제약을 완화할 수 있다. As described above, according to the present invention, fresh water is passed through an osmosis membrane to generate pressure, and the generated water mixed with brine and fresh water is again passed through a reverse osmosis membrane to remove fresh water, so that salt water and fresh water can be circulated and reused. It is possible to reduce the supply of salt water and prevent the occurrence of salt water mixed with fresh water, thereby preventing environmental pollution, and it is possible to improve the power generation efficiency when the salt water is generated by the same amount of salt, It is possible to relax the restriction on the installation place of the power generation device.
