Description

대형 배관이 구비된 역삼투압 담수화처리장치{Reverse osmosis freshwater treatment apparatus with big diameter pipe}Reverse osmosis freshwater treatment apparatus with big diameter pipe}

본 고안은 흡입배관이 구비된 역삼투압 담수화처리장치에 관한 것으로, 더욱 상세하게는 1차멤브레인과 2차멤브레인 사이에 대형 배관을 설치하여 물의 오염을 방지할 수 있도록 한 것이다.The present invention relates to a reverse osmosis desalination treatment apparatus equipped with a suction pipe, and more particularly, to install a large pipe between the primary membrane and the secondary membrane to prevent contamination of water.

일반적으로, 고농도염이 함유된 바닷물을 담수화하여 식수화시키는 방법으로서, 상변화가 일어나는 다단증발법, 다중효용법, 증기압축법, 투과기화법과 같은 증발법 및 냉동법, 가스수화물법과 같은 결정법이 이용되거나 또는 상변화가 일어나지 않는 역삼투압법, 전기투석법과 같은 막법이나 용매추출법 및 이온교환수지법 등의 다양한 방법이 이용되고 있다.In general, as a method of desalination and drinking water containing high concentration salts, evaporation methods such as multi-stage evaporation method, multiple utility method, vapor compression method, pervaporation method, etc., in which a phase change occurs, or crystallization methods such as freezing method and gas hydrate method are used. Alternatively, various methods such as a membrane method such as reverse osmosis and electrodialysis, a solvent extraction method, and an ion exchange resin method in which a phase change does not occur are used.

이러한 담수화방법중 종래의 일반적인 역삼투압법을 수행하기 위한 시스템에대하여 설명하면(2단계 역삼투압 설비의 경우), 첨부된 예시도면 도 1에 도시된 바와 같이, 해수펌프(2)를 거쳐 전처리 및 카트리지 필터부(4)를 통과한 해수는 배관라인(4A)를 거쳐 1차고압펌프(6)를 통해 1차 멤브레인(8)으로 공급되고, 1개 배관라인(8A)은 중간탱크(Intermediate tank)(10)를 거치게되고, 다른 1개 배관라인(8B)은 곧바로 2차 탱크인 탈염수 탱크(12)로 공급된다.Referring to the system for performing a conventional general reverse osmosis method of such a desalination method (in the case of a two-stage reverse osmosis equipment), as shown in the accompanying drawings, Figure 1, through the sea water pump (2) pretreatment and The seawater passing through the cartridge filter part 4 is supplied to the primary membrane 8 through the primary high pressure pump 6 via the piping line 4A, and one piping line 8A is an intermediate tank. 10), the other pipe line 8B is directly supplied to the desalted water tank 12, which is a secondary tank.

그리고, 상기 1차 멤브레인(8)으로 분기된 1개의 배관(8C) 라인은 고농도 상태의 브라인(brine)을 다시 바다로 방출하도록 구성된다. 또한, 상기 중간탱크(10)로부터 플러싱펌프(Flushing Pump)(14)를 통해 카트리지필터(4)와 고압펌프(6)를 연결해주는 배관라인(4A)상에 연결되어 1차고압펌프(6) 및 1차 멤브레인(8)을 순환하면서 씻어주도록 되어있다.In addition, one pipe 8C line branched to the primary membrane 8 is configured to discharge high concentration brine back to the sea. In addition, the primary high pressure pump 6 is connected to a pipe line 4A connecting the cartridge filter 4 and the high pressure pump 6 through a flushing pump 14 from the intermediate tank 10. And rinsing while circulating the primary membrane (8).

또한, 상기 중간탱크(10)의 일측에는 2차 고압펌프(16)가 갖추어져 2차멤브레인(18)를 거쳐 탈염수탱크(12)와 연결된다.In addition, one side of the intermediate tank 10 is provided with a secondary high pressure pump 16 is connected to the desalination tank 12 via the secondary membrane 18.

도면중 19는 에너지회수용 터빈이다.19 is an energy recovery turbine.

이러한 종래의 역삼투압 시스템에서 해수를 이용할 때 담수의 수질을 맞추기 위해 2단계의 1,2차 멤브레인(8)(18)을 통과하는데, 만일 예기치않게 전원공급이 차단되어 펌프의 작동이 정지하게되면, 삼투압현상에 의해 중간탱크(10)안에 있어 유체인 물이 거꾸로 배관라인(8A)를 통해 딸려올라가게 되는 현상(흡입배압)(suck back pressure)이 발생하기도 한다.When using seawater in such a conventional reverse osmosis system, it passes through two stages of the first and second membranes (8) and (18) to adjust the fresh water quality. If the power supply is unexpectedly interrupted and the pump stops working, In the intermediate tank 10 due to osmotic pressure, a phenomenon in which water, which is a fluid, rises upside down through the pipe line 8A (suck back pressure) may occur.

그런데, 여기서, 종래에는 중간탱크(10)안에 채류하고 있던 물이 2차 멤브레인(18)을 거쳐 탈염수탱크(12)로 흐르기 때문에, 중간탱크(10)안의 물은 소독되지않은 상태이면서 일정시간동안 채류하므로 박테리아가 생성될 우려가 높고, 탱크내부에서의 온도상승으로 인해 2차멤브레인(18)의 성능에 악영향을 주는 문제점이 있었다.By the way, since the water collected in the intermediate tank 10 flows to the desalination tank 12 through the secondary membrane 18 conventionally, the water in the intermediate tank 10 is not disinfected and is for a predetermined time. Since there is a high risk of bacteria generated by the extraction, there is a problem that adversely affects the performance of the secondary membrane 18 due to the temperature rise in the tank.

이에 본 고안은 상기와 같은 종래의 문제점을 해결하기위한 것으로, 배관을 설치하여 종래의 중간탱크 대신에 1차 멤브레인과 2차 멤브레인과의 사이에 대형배관을 구비하여 중간탱크안에서의 체류에 따른 물의 오염이 발생하지 않고 흐르도록 한 역삼투압 담수화처리장치를 제공함에 그 목적이 있다.The present invention is to solve the above-mentioned problems, the installation of a pipe provided with a large pipe between the primary membrane and the secondary membrane instead of the conventional intermediate tank of the water according to the retention in the intermediate tank It is an object of the present invention to provide a reverse osmosis desalination treatment device that allows pollution to flow without generation.

본 고안은 도 2에 도시된 바와 같이, 통상의 역삼투압방식의 해수의 담수화처리장치에 있어서, 1차 멤브레인(8)과 2차멤브레인(18)의 사이에 대형배관(20)이설치된 구조이다.The present invention, as shown in Figure 2, in the conventional desalination treatment of seawater of the reverse osmosis method, a large pipe 20 is installed between the primary membrane (8) and the secondary membrane (18). .

이와 같이 구성된 본 고안은 배관(20)만으로 형성되어 있으므로, 물의 연속해서 흐르게된다. 따라서, 물의 일시체류현상이 없게되어 박테리아등의 생성현상이 방지된다.The present invention configured as described above is formed of only the pipe 20, so that water flows continuously. Therefore, there is no temporary retention of water, and production of bacteria and the like is prevented.

또한, 상기 대형배관(20)은 어느정도 큰 직경을 가진 배관을 의미한다. 이 대형배관(20)의 사이즈로 인해 유사시의 흡입배압현상이 발생하더라도 이를 수용할 수 있으므로, 역류로 인한 1차멤브레인(8)의 손상을 방지할 수 있다.In addition, the large pipe 20 means a pipe having a somewhat larger diameter. Due to the size of the large pipe 20 can be accommodated even if the suction back pressure phenomenon occurs in case of emergency, it is possible to prevent damage to the primary membrane (8) due to backflow.

이와 같이 본 고안에 의하면, 1차멤브레인과 2차멤브레인의 사이에 큰 직경의 배관을 설치하여 물이 흐르도록 되어 있어 채류시간이 없어 종래와 같이 탱크안에 있게되어 오염되는 현상을 방지할 수 있는 효과가 있다.As such, according to the present invention, a large diameter pipe is installed between the primary membrane and the secondary membrane so that water flows, and thus, there is no holding time, thereby preventing contamination by being in the tank as in the prior art. There is.
