본 발명은 담수화설비의 기자재 또는 배관에서 샘플을 채취하는 장치에 관한 것으로서, 특히 진공상태인 기자재 또는 배관으로부터 담수 또는 담수화중인 샘플을 채취하기 위한 밸브(Valve)의 사용개수를 줄일 수 있을 뿐만 아니라, 샘플을 용 이하게 채취할 수 있는 담수화설비의 기자재 또는 배관에서 샘플을 채취하는 장치에 관한 것이다. The present invention relates to a device for collecting a sample from the equipment or pipe of the desalination plant, and in particular, it is possible to reduce the number of use of the valve (Valve) for taking a sample of fresh water or desalination from the equipment or pipe in a vacuum state, The present invention relates to a device for collecting a sample from equipment or pipe of a desalination plant that can easily collect a sample.

담수화설비는 생활용수나 공업용수로 직접 사용할 수 없는 물, 예컨대 바닷물, 짠 지하수, 오수 등을 사용가능한 물, 즉 담수로 만드는 설비를 말한다. The desalination plant refers to a facility that makes water available for living or industrial water, such as seawater, salty groundwater, sewage, etc., that is, freshwater.

담수화설비를 이용한 담수화 방법은 크게 증발법과 막여과법으로 대별할 수 있다. 증발법에는 다단 플래쉬법(Multiple Stage Flash, MSF), 다중 효용법(Multiple Effect Distillation, MED), 증발압축법(Vapor Compression, VC) 등의 방법이 있다. 또한, 막여과법에는 압력을 이용하는 역삼투압법(Reverse Osmosis, RO), 전기를 이용하는 전기투석막법(Electro Dialysis, ED) 등의 방법이 있다. 그 외에, 냉열법(Freezing Process), 이온교환수지법(Ion Exchange) 등의 방법도 사용되고 있으며, 또한 상기한 방법을 둘 이상 혼합한 하이브리드 타입(Hybrid Type)의 방법도 사용되고 있다. Desalination using desalination facilities can be roughly classified into evaporation and membrane filtration. Examples of the evaporation method include a multiple stage flash (MSF) method, a multiple effect distillation method (MED), and a vapor compression method (Vapor Compression, VC). In addition, membrane filtration includes reverse osmosis (RO) using pressure, electrodialysis (ED) using electricity, and the like. In addition, methods such as a freezing process and an ion exchange method are also used, and a hybrid type method in which two or more of the above methods are mixed is also used.

상기한 바와 같은 여러 가지 방법들 중에서 상업적으로 성공한 방법은 증발법으로 다단 플래쉬법과 다중 효용법이다. Among the various methods described above, the commercially successful method is the multi-stage flash method and the multi-utility method as the evaporation method.

다단 플래쉬법은, 현재 대용량 담수화장치에 가장 널리 사용되는 담수화기술로서, 해수를 가열하면 수증기가 되고, 이 수증기를 다시 응축시켜 담수를 얻는 방법인데, 이 때 응축되는 수증기는 관내로 흐르는 해수를 가열하는 열원으로 사용된다. 이러한 과정이 이루어지는 1개의 단위를 단(Stage)이라 하며, 단을 여러 개 연결하여 담수생산 과정을 여러 번 반복하도록 만든 것이 다단 플래쉬법이다. 이 다단 플래쉬은, 낮은 온도와 압력의 증기를 열원으로 사용하는 프로세스를 가지고 있 으므로, 발전소의 폐열을 이용한 담수생산에 적합하다. 다단 플래쉬법이, 후술하는 다단 효용법과 다른 점은, 다단 효용법이 증발과 내에서 증발이 일어나는데 비해, 상대적으로 고압의 열교환기 내에서 가열된 해수가 오리피스를 통해 저압의 격실로 분출되면서 증발이 일어나게 된다. 이 때, 전체의 열에너지는 동일한 상태로 각 격실에서 외부로부터의 열공급이 없으므로, 원수의 잉여 에너지에 해당하는 부분만의 잠열로 변환되기 때문에 각 격실에서의 증발량은 수% 이내이다. 다단플래쉬방식의 일반적인 계통은 점차 진공도가 높은 격실이 직렬로 이어진 형태를 가진다.The multi-stage flash method is the most widely used desalination technology in large-capacity desalination systems, and when seawater is heated, it becomes water vapor and condenses this water vapor to obtain fresh water. At this time, the condensed water vapor heats the seawater flowing into the pipe. It is used as a heat source. One unit of the process is called a stage (stage), it is a multi-stage flash method to make the fresh water production process repeated several times by connecting multiple stages. This multi-stage flash has a process using low temperature and pressure steam as the heat source, making it suitable for freshwater production using waste heat from power plants. The multi-stage flash method differs from the multi-stage utility method described later in that the multi-stage utility method evaporates within the evaporation zone, whereas the evaporation is generated when the seawater heated in the relatively high pressure heat exchanger is ejected through the orifice into the low pressure compartment. Get up. At this time, since the heat energy of the whole is the same state and there is no heat supply from the outside in each compartment, since it is converted into the latent heat of only the part corresponding to surplus energy of raw water, the amount of evaporation in each compartment is within several%. The general system of the multi-stage flash system has a form in which a vacuum chamber with a high degree of vacuum is gradually connected in series.

또한, 다중 효용법은, 단순 증류기를 시리즈로 배열한 형태로, 첫 번째의 증발기에 보일러에서 발생된 증기로 열을 가하여 해수를 증발시키면, 발생된 증기는 다음 효용(Effect)의 증발기에서 응축되어 담수가 되고, 동시에 가열원으로 작용하여 증발기 내부의 해수를 증발시킨다. 또한, 이 때 발생된 증기는 다시 다음 효용의 증발기에서 가열원으로 작용한다. 이 때, 각 효용 증발기 내의 압력을 차례로 낮게 유지하여 효용이 진행됨에 따라, 더 낮은 온도에서 비등이 일어나도록 해주어야 한다. 또한, 각 효용에서 생산된 담수의 온도가 상온보다 높기 때문에 유입되는 해수와 상호 열교환시켜 생산담수의 현열을 회수하는 방법도 널리 채택되고 있다. 이러한 과정은 금속관 외부가 진공상태에서 진행되므로, 분무되는 해수가 낮은 온도에서도 끓어오르게 된다. 다단증발법과 크게 다른 것은 60~70℃의 낮은 온도에서 운전되므로, 비교적 중/소형이지만 열효율이 높고, 전력소모량이 생산량에 비해 적은 장점이 있다. In addition, in the multi-utilization method, a series of simple distillers are arranged. When the first evaporator is heated with steam generated in a boiler to evaporate seawater, the generated steam is condensed in the next effective evaporator. It becomes fresh water and at the same time serves as a heating source to evaporate the seawater inside the evaporator. In addition, the steam generated at this time serves as a heating source in the next useful evaporator. At this time, the pressure in each utility evaporator must be kept low in order to allow boiling to occur at a lower temperature as the utility progresses. In addition, since the temperature of fresh water produced in each utility is higher than room temperature, a method of recovering sensible heat of freshwater produced by mutual heat exchange with incoming seawater is also widely adopted. This process is carried out in a vacuum state outside the metal tube, so that the seawater to be sprayed boils even at low temperatures. Significantly different from the multi-stage evaporation method is that it is operated at a low temperature of 60 ~ 70 ℃, it is relatively medium / small, but the thermal efficiency is high, the power consumption is less than the output.

상기한 바와 같은 각종 방식의 담수화설비에는 각종 기자재 또는 배관이 설 치되어 있는데, 이것들 중에서 일부는 대기압보다 훨씬 낮은 진공 상태에 놓이게 되며, 필요에 의해서 기자재 또는 배관 내부의 샘플을 채취하고 싶을 때에는, 기자재 또는 배관 내부의 진공 상태가 샘플 채취시 영향을 받지 않도록 기술적인 사항들을 검토하여야 한다. Various desalination facilities as described above are equipped with various equipments or pipes, some of which are placed in a vacuum much lower than atmospheric pressure. Alternatively, technical details should be reviewed to ensure that the vacuum inside the pipe is not affected by sampling.

도 1에는, 대략 0.2bara 정도의 진공상태인 기자재 또는 배관(10)에서 샘플을 채취하는 종래 장치가 도시되어 있는데, 기자재 또는 배관(10)에 노즐(Nozzle, 12)을 설치되고, 상기 노즐(12)에 연결되는 관로(30)에 2개의 밸브(20, 22)가 설치되어 있다. 밸브 1개 사용시 밸브를 열면 외부의 압력이 높으므로 외부의 공기가 유입된다. In Fig. 1, a conventional apparatus for collecting a sample from equipment or pipe 10 in a vacuum state of about 0.2 bara is shown. A nozzle 12 is installed in the equipment or pipe 10, and the nozzle ( Two valves 20 and 22 are provided in the pipeline 30 connected to 12). When using one valve, open the valve, the outside pressure is high, so the outside air flows in.

기자재 또는 배관(10)으로부터 샘플을 채취할 경우에는, 우선 제1밸브(20)를 열어 유체가 제2밸브(22) 앞에까지 차도록 한 다음, 제1밸브(20)를 잠그고 제2밸브(22)를 열어 용기(40)에 샘플(S)을 받는다. When taking a sample from the equipment or pipe 10, first open the first valve 20 to fill the fluid up to the second valve 22, then lock the first valve 20, the second valve (22) ) To receive the sample (S) in the container (40).

그러나, 상기한 바와 같은 종래 샘플 채취 장치에 있어서는, 2개의 밸브(20, 22)가 필요하고 2개의 밸브(20, 22)를 조작하여야 하므로, 비경제적일 뿐만 아니라, 샘플(S)을 채취하는 작업도 번거로운 문제점이 있다. However, in the conventional sampling apparatus as described above, since two valves 20 and 22 are required and two valves 20 and 22 must be operated, it is not only economical, but also the sample S Work also has troublesome problems.

본 발명은 상기한 종래 문제점을 고려하여 이루어진 것으로서, 진공상태인 기자재 또는 배관으로부터 담수 또는 담수화중인 샘플을 채취하기 위한 밸브의 사용개수를 줄일 수 있을 뿐만 아니라, 샘플을 용이하게 채취할 수 있도록 하는 것을 목적으로 한다.
The present invention has been made in consideration of the above-described conventional problems, and it is possible to reduce the number of valves used for collecting fresh or desalted samples from vacuum equipment or pipes, and to easily collect samples. The purpose.

상기 목적을 달성하기 위하여, 본 발명에 따른 담수화설비의 기자재 또는 배관에서 샘플을 채취하는 장치는, 담수화설비의 진공상태인 기자재 또는 배관에, 그 내부의 샘플을 배출시킬 수 있도록 설치되는 노즐과; 상기 노즐에 관로에 의하여 연결되는 밸브와; 그리고, 상기 밸브의 개방동작시 상기 노즐, 밸브 및 관로를 통하여 배출되는 샘플을 수용할 수 있도록, 상기 관로의 출구에 착탈가능하게 연결되는 샘플채취용기;를 포함하여 이루어지는 것을 특징으로 한다. In order to achieve the above object, the apparatus for taking a sample from the equipment or pipe of the desalination plant according to the present invention, the nozzle or the equipment installed in the vacuum equipment of the desalination plant or the pipe is installed to discharge the sample; A valve connected to the nozzle by a conduit; And a sampling container detachably connected to the outlet of the pipe so as to accommodate the sample discharged through the nozzle, the valve, and the pipe during the opening operation of the valve.

본 발명의 특징 및 이점들은 첨부도면에 의거한 다음의 상세한 설명으로 더욱 명백해질 것이다. 이에 앞서, 본 명세서 및 청구범위에 사용된 용어나 단어는, 발명자가 그 자신의 발명을 가장 최선의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의할 수 있다는 원칙에 입각하여 본 발명의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다. The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are based on the principle that the inventor can appropriately define the concept of terms in order to explain the invention in the best way. It should be interpreted as meanings and concepts corresponding to

도 2에는, 본 발명에 따른 담수화설비의 기자재 또는 배관에서 샘플을 채취하는 장치가 도시되어 있다. 2 shows an apparatus for collecting a sample from equipment or piping of a desalination plant according to the present invention.

참조부호 100은, 담수화설비를 구성하는 기자재 또는 배관을 나타내는 것으로서, 그 내부압력은 대략 0.2bara 정도의 진공상태가 유지된다. 상기 기자재 또는 배관(100)에는 담수 또는 담수화중인 유체가 저장 또는 유동하게 된다. Reference numeral 100 denotes a material or a pipe constituting the desalination plant, and its internal pressure is maintained at about 0.2 bara in vacuum. Fresh water or desalination fluid is stored or flowed into the equipment or pipe 100.

본 발명에 따르면, 상기 진공상태인 기자재 또는 배관(100) 내부의 유체를 샘플로 채취하기 위하여, 상기 기자재 또는 배관(100)의 외주면 일측에는 노즐(102)이 설치되고, 상기 노즐(102)에는 관로(130)에 의하여 밸브(120)가 연결된다. 따라서, 상기 밸브(120)의 폐쇄동작시에는 노즐(102)과 연결된 관로(130)가 폐쇄되므로, 기자재 또는 배관(100) 내부의 유체가 관로(130)를 통하여 배출될 수 없는 상태에 놓이고, 상기 밸브(120)의 개방동작시에는 노즐(102)과 연결된 관로(130)가 개방되므로, 기자재 또는 배관(100) 내부의 유체가 관로(130)를 통하여 배출될 수 있는 상태에 놓인다. According to the present invention, in order to sample the fluid inside the vacuum equipment or the pipe 100 as a sample, a nozzle 102 is installed on one side of the outer peripheral surface of the equipment or pipe 100, and the nozzle 102 The valve 120 is connected by the conduit 130. Therefore, in the closing operation of the valve 120, the pipeline 130 connected to the nozzle 102 is closed, so that the fluid inside the equipment or the pipe 100 cannot be discharged through the pipeline 130. In the opening operation of the valve 120, the conduit 130 connected to the nozzle 102 is opened, and thus the fluid inside the equipment or the pipe 100 may be discharged through the conduit 130.

상기한 바와 같은 밸브(120)의 개방동작시 관로(130)를 통해 배출되는 유체를 샘플로 받기 위하여, 상기 관로(130)의 출구에는 샘플채취용기(140)가 착탈가능하게 연결된다. In order to receive the fluid discharged through the conduit 130 as a sample during the opening operation of the valve 120 as described above, the sampling container 140 is detachably connected to the outlet of the conduit 130.

다음에, 상기한 바와 같이 구성된 본 발명에 따른 담수화설비의 기자재 또는 배관에서 샘플을 채취하는 장치의 작용에 대하여 설명한다. Next, a description will be given of the operation of the apparatus for collecting a sample from the equipment or pipe of the desalination plant according to the present invention configured as described above.

필요에 따라 샘플을 채취하고자 할 경우, 밸브(120)가 폐쇄동작중인 상태에서, 관로(130)의 출구에 샘플채취용기(140)를 연결한다. 다음에, 밸브(120)를 개방동작시킨다. 따라서, 상기 밸브(120)의 개방동작에 의하여 관로(130)는 개방되므로, 샘플채취용기(140)의 내부와 기자재 또는 배관(100)의 내부가 서로 통하는 상태에 놓이게 된다. 이 상태가 되면 샘플채취용기(140)의 내부와 기자재 또는 배관(100)의 내부가 하나의 닫힌 계를 형성하게 되므로, 유체의 평형 원리에 따라 양자의 압력이 동일하게 된다. 즉, 압력이 높은 곳에서 낮은 곳으로 이동하는 공기(유체)의 특성상 샘플채취용기(140) 내부의 공기가 진공상태인 기자재 또는 배관(100) 측으로 이동하여 양 용기의 압력이 동일하게 변화되는 것이다. 이때, 기자재 또는 배관(100)의 용량이 샘플채취용기(140)의 용량에 비해 매우 크기 때문에 기자재 또는 배관(100) 측의 압력은 거의 변화되지 않는다.
그리고, 상기 샘플채취용기(140)의 내부의 공기가 기자재 또는 배관(100) 측으로 이동함에 따라 발생하는 빈자리에 기자재 또는 배관(100) 측의 유체가 유입된다. 즉, 상기 샘플채취용기(140)가 기자재 또는 배관(100)의 하부에 위치하므로, 기자재 또는 배관(100)과 샘플채취용기(140)의 내부 압력이 동일한 상태에서는 기자재 또는 배관(100)의 유체가 중력에 의해 자연스럽게 샘플채취용기(100)로 이동되는 것이다.When the sample is to be taken as needed, in the state in which the valve 120 is closed, the sampling container 140 is connected to the outlet of the conduit 130. Next, the valve 120 is opened. Therefore, since the pipe line 130 is opened by the opening operation of the valve 120, the inside of the sample container 140 and the inside of the equipment or the pipe 100 are in a state of communicating with each other. In this state, since the inside of the sampling container 140 and the inside of the equipment or the pipe 100 form one closed system, the pressures of the two are the same according to the equilibrium principle of the fluid. That is, due to the characteristics of air (fluid) moving from a high pressure to a low place, the air inside the sampling container 140 moves to the equipment or the pipe 100 in a vacuum state so that the pressure of both containers is changed in the same manner. . At this time, since the capacity of the equipment or pipe 100 is very large compared to the capacity of the sampling container 140, the pressure of the equipment or pipe 100 is hardly changed.
Then, the fluid of the equipment or pipe 100 is introduced into the empty space generated as the air in the sample container 140 moves to the equipment or pipe 100 side. That is, since the sample container 140 is located below the equipment or pipe 100, the fluid of the equipment or pipe 100 may be in a state where the internal pressure of the equipment or pipe 100 and the sample container 140 are the same. Is naturally moved to the sample container 100 by gravity.

샘플채취용기(140)에 유체 샘플이 필요한 양만큼 수용되면, 밸브(120)를 다시 폐쇄동작시키고, 관로(130)로부터 샘플채취용기(140)를 분리시킨다. When the fluid sample is accommodated in the sampling container 140 in the required amount, the valve 120 is closed again, and the sampling container 140 is separated from the conduit 130.

상기한 바와 같이 구성된 본 발명에 따른 담수화설비의 기자재 또는 배관에서 샘플을 채취하는 장치에 의하면, 하나의 밸브(120)만 사용하여 샘플을 채취할 수 있으므로, 경제적이다. According to the apparatus for collecting a sample from the equipment or pipe of the desalination plant according to the present invention configured as described above, it is economical because the sample can be taken using only one valve 120.
