Description

복수탈염시스템 및 방법 {Condensate Polishing System and Method}Condensate Polishing System and Method

본 발명은 복수 중에 포함된 이온성분들을 제거하는 복수탈염시스템에 관한 것으로, 보다 상세하게는 유입되는 복수 중 소량의 복수가 항상 복수탈염장치를 통과하면서 처리됨과 동시에 복수의 전도도 및 불순물의 농도에 따라 정상운전과 우회운전이 자동적으로 교체되어 시행되도록 된 복수탈염시스템 및 방법에 관한 것이다.
The present invention relates to a plural desalination system for removing ionic components contained in plural, and more particularly, a small amount of plural plural plural plural plural plural inflows are processed while passing through the plural desalination apparatus and at the same time according to the plurality of conductivity and concentration of impurities. The present invention relates to a multiple desalination system and method in which normal operation and bypass operation are automatically replaced and implemented.

일반적으로, 원자력발전소나 화력발전소 등에서 스팀을 생산하는 계통수 내의 나트륨이온이나 염소이온의 증가는 응축기의 냉각수로 사용하는 바닷물이 누수 되어 유입되는 경우 발생한다.
In general, an increase in sodium ions or chlorine ions in the system water producing steam in a nuclear power plant or a thermal power plant occurs when the seawater used as the cooling water of the condenser leaks.

한편, 계통수 내의 불순물은 순환계통 배관의 산화에 의해 발생되는 산화철분이 대부분이다. 이러한 산화철분은 매우 작은 입자로 대부분 복수탈염장치의 이온교환수지층에서 제거된다. 이러한 이유로, 이온교환수지를 사용하는 종래의 복수탈염시스템은 유입수의 질에 상관없이 유입수를 모두 복수탈염장치를 통과시켜 복수 중의 이온성분과 입자성분을 제거한다.On the other hand, most of the impurities in the system water is iron oxide powder generated by oxidation of the circulation system piping. These iron oxide powders are very small particles and are mostly removed from the ion exchange resin layer of the multiple desalination apparatus. For this reason, the conventional multiple desalination system using ion exchange resin removes the ionic component and the particle component in the plurality of inflow water through the multiple desalination apparatus, regardless of the quality of the influent.

그러나 종래의 복수탈염장치는 이온교환수지로 복수와 함께 유입되는 산화철 입자들을 완벽하게 제거하지 못하기 때문에, 이온교환수지층에서 여과 제거되지 않은 입자들이 계통수를 통해 증기발생기로 유입되고 누적되어 증기발생기 튜브를 부식시켜 발전소 운전에 많은 문제를 초래한다.
However, since the conventional desalination apparatus does not completely remove iron oxide particles introduced with the plurality into the ion exchange resin, the particles not filtered out from the ion exchange resin layer flow into the steam generator through the system water and accumulate. Corrosion of the tubes causes many problems in plant operation.

특히, 유입되는 철분들이 산소와 반응하여 강력한 산화성 물질을 생성하여 양이온교환수지와 음이온교환수지를 산화시켜서 SO4?이온과 Cl?이온을 증가시켜 부식비율이 높아지게 된다. 이러한 누적된 철분 슬러지를 제거하기 위하여 약품세정을 하며 이로 인하여 다량의 세정폐액이 발생되는 악순환이 초래된다.
In particular, the incoming iron reacts with oxygen to produce a strong oxidizing substance, oxidizes cation exchange resins and anion exchange resins to increase SO4? And Cl? Ions, thereby increasing the corrosion rate. Chemical cleaning is performed to remove the accumulated iron sludge, which causes a vicious cycle in which a large amount of cleaning waste is generated.

또, 종래의 이온교환수지를 이용한 복수탈염장치는 정지시에 이온교환수지층에서 교환된 이온들이 누출되고 다시 가동시에는 누출된 이온을 포함한 물을 버리고 운전해야한다. 따라서 응축기에서 해수 누수에 따른 불순물이나 이온성분들이 갑작스럽게 유입되는 경우 즉시 대처하기가 어렵게 된다.
In addition, a conventional desalination apparatus using an ion exchange resin has to be operated by discharging ions exchanged from the ion exchange resin layer when stopped and discarding the water containing the leaked ions upon operation. Therefore, it is difficult to immediately deal with impurities or ions caused by sea water leakage in the condenser.

또한, 종래의 복수탈염장치는 해수의 누수가 없어 Na이온과 Cl이온의 증가가 거의 없는 등 유입수의 이온성분이 기준치 이하인 경우에도 복수탈염장치를 가동시켜 유입수를 통과시키므로 불필요한 가동을 하게 된다.
In addition, the conventional desalination apparatus does not need operation because the desalination apparatus is operated by passing the inflow water even when the ionic component of the inflow water is less than the reference value such as there is little leakage of sea water and there is little increase in Na ions and Cl ions.

이러한 복수탈염장치의 불필요한 가동으로 인하여 장치 내부의 부식을 억제하기 위하여 주입되어 있는 에탄올아민(ETA)이나 암모니아, 하이드라진과 같은 약품이 이온교환수지층에서 불필요하게 제거되어 복수탈염 이후에 다시 주입해야 한다. 이와 같은 불필요한 가동과 약품의 투여로 가동비용이 상승하게 된다.
Due to the unnecessary operation of the desalination system, ethanolamine (ETA), ammonia and hydrazine, which are injected in order to suppress corrosion inside the apparatus, are unnecessarily removed from the ion exchange resin layer and must be re-injected after desalination. . This unnecessary operation and administration of the drug will increase the operating cost.

본 발명은 위와 같은 문제점을 해결하기 위하여, 응축기에서 해수 누수에 따른 불순물이나 이온성분들이 갑작스럽게 유입되는 경우에도 즉시 대처가 가능하고, 유입되는 복수의 전도도 및 불순물의 농도에 따라 정상운전과 우회운전이 자동적으로 교체되어 시행되는 복수탈염시스템 및 방법을 제공하는 데에 그 목적이 있다.
In order to solve the above problems, the present invention can immediately cope with impurities or ionic components due to sea water leakage from the condenser, and the normal operation and the bypass operation according to the concentration of the plurality of conductivity and impurities introduced The purpose is to provide a multiple desalination system and method that is automatically replaced and implemented.

본 발명은 위와 같은 목적을 달성하기 위하여, 복수탈염장치(80), 유입수밸브(11)를 구비한 유입수관로(1) 및 처리수밸브(21)를 구비한 처리수관로(2)로 구성되는 복수탈염시스템에 있어서, 상기 유입수관로(1) 상에 정밀여과기(60)와 분석장치(70)를 설치하고, 제1우회수밸브(31)를 구비하고 상기 분석장치(70) 이후의 유입수관로(1)와 처리수관로(2)를 연결하는 제1우회수관로(3)설치하며, 제2우회수밸브(41)를 구비하고 상기 분석장치(70) 이후의 유입수관로(1)와 상기 유입수밸브(11) 이후의 유입수관로(1)를 연결하는 제2우회수관로(3)를 설치하고, 처리수우회밸브(51)를 구비하고 상기 처리수관로(2)의 처리수밸브(21) 전후의 처리수관로(2)를 연결하는 처리수우회관로(5)를 설치한 복수탈염시스템과 상기 복수탈염시스템을 이용하는 복수탈염방법을 특징으로 한다.
In order to achieve the above object, the present invention comprises a plurality of desalination apparatus (80), an influent water pipe (1) having an inlet water valve (11), and a treated water pipe (2) having a treatment water valve (21). In the multiple desalination system, a precision filter 60 and an analyzer 70 are installed on the inlet pipe 1, and a first bypass valve 31 is provided and the inlet pipe after the analyzer 70 is installed. (1) and the first bypass pipe (3) is installed to connect the treated water pipe (2), provided with a second bypass valve 41 and the inlet water pipe (1) and the after the analysis device 70 A second bypass water pipe (3) is provided to connect the inflow water pipe (1) after the inflow water valve (11), and includes a treatment water bypass valve (51) and a treatment water valve (21) of the treatment water pipe (2). A plurality of desalination systems in which the treatment water pipe passage 5 connecting the front and rear treatment water pipe passages 2 and the plurality of desalination systems are used.

본 발명은 유입되는 복수의 전도도 및 불순물의 농도에 따라 정상운전과 우회운전이 자동적으로 교체되어 시행되므로 복수탈염장치의 가동이 최소화되고 재생약품이 절감되며, 재생폐액의 발생도 적게 되어 가동비용이 절감되는 효과가 있다.
According to the present invention, since the normal operation and the bypass operation are automatically replaced according to the conductivity of the plural conductivity and the impurity concentration, the operation of the plural desalination apparatus is minimized, the regeneration chemical is reduced, and the amount of the regeneration waste liquid is reduced, thereby reducing the operating cost. There is a saving effect.

또, 본 발명은 복수탈염장치에 대한 부하가 줄게 되어 복수탈염장치의 가동에 따른 신뢰성이 증대될 뿐만 아니라, 이온교환수지의 재생 횟수가 크게 줄게 되고 재생과정에서의 교차오염에 의한 이온의 누출이 차단되어 부식이 최소화되는 효과가 있다.
In addition, the present invention reduces the load on the plurality of desalination apparatuses, thereby increasing the reliability of the operation of the plurality of desalination apparatuses, greatly reducing the number of regeneration of the ion exchange resins, and reducing the leakage of ions due to cross-contamination during the regeneration process. Blocking has the effect of minimizing corrosion.

또, 본 발명은 정밀여과기를 통과하는 복수 중 소량의 복수가 항상 복수탈염장치를 통과하면서 처리되고 있어 복수탈염장치의 이온교환수지층에서 교환된 이온들이 누출되어 누출된 이온을 포함한 물을 버리고 운전해야 하는 일이 발생하지 아니하므로, 응축기에서 해수가 누수되어 복수의 전도도가 급격하게 올라가 오염된 복수가 복수탈염장치로 유입되더라도 긴급처리가 가능하여 계통수의 오염을 방지할 수 있는 효과가 있다.
In addition, the present invention is processed while a small amount of the plurality of the plurality passing through the precision filter is always passed through the plurality of desalination apparatus, the ions exchanged in the ion exchange resin layer of the plurality of desalination apparatus leaks and discards the water containing the leaked ions Since there is no need to occur, even if the contaminated water is leaked from the condenser, a plurality of conductivity is rapidly increased, even if the contaminated plurality is introduced into the plural desalination apparatus, there is an effect that can prevent the contamination of the system water.

또한, 본 발명은 정밀여과기 등 새로운 기기를 추가하고 운전방법만을 변경하면 기존에 사용하고 있는 복수탈염장치에도 쉽게 적용할 수 있는 효과가 있다.
In addition, the present invention has an effect that can be easily applied to the existing multiple desalination apparatus by adding a new device such as a precision filter and only changing the operation method.

다음에 이와 같은 본 발명 복수탈염시스템의 작용에 대하여 설명한다. 본 발명 복수탈염시스템을 가동하면, 먼저 상기 제2유입수우회밸브(41)와 처리수우회밸브(51)가 열려 상기 정밀여과기(60)를 통과하는 복수 중 약 5% 정도의 소량의 복수가 수질과 상관없이 항사 복수탈염장치(80)를 통과하면서 처리된다.
Next, the operation of the multiple desalination system of the present invention will be described. When the multiple desalination system of the present invention is operated, first, the second inflow bypass valve 41 and the treated water bypass valve 51 are opened, and a plurality of small quantities of about 5% of the plurality passing through the precision filter 60 are water quality. Irrespective of the process, it is processed while passing through the constant multiple desalination apparatus (80).

이어서 상기 분석장치(70)가 상기 정밀여과기(60)에 의해 여과된 복수의 성분을 측정하고 기준치와 비교 분석하여, 측정치가 기준치 이하인 경우에는 제1우회수밸브(31)를 열고 유입수밸브(11)와 처리수밸브(21)를 닫아서, 정밀여과기(60)를 통과하는 대부분의 복수가 상기 복수탈염장치(80)를 거치지 않고 제1우회수관로(3)로 우회하여 상기 처리수관로(2)를 통하여 발전계통 또는 증기발생기로 공급된다.
Subsequently, the analysis device 70 measures a plurality of components filtered by the precision filter 60 and compares the result with a reference value. When the measured value is equal to or less than the reference value, the first bypass valve 31 is opened to open the inlet valve 11. ) And the treated water valve 21 to bypass most of the plurality passing through the microfiltration unit 60 to the first bypass water pipe (3) without passing through the plurality of desalination apparatus (80). It is supplied to the power generation system or steam generator through).

한편, 이러한 본 발명 복수탈염시스템을 일정기간 우회운전하면, 이전에 주입되어 있던 약품 특히, 하이드라진 등이 높은 열에 의해 분해되어 암모니아로 변하고, 이것이 복수의 전도도를 상승시켜 기준치보다 높아지게 된다.
On the other hand, when the dehydration system of the present invention is detoured for a certain period of time, the previously injected medicine, in particular, hydrazine, is decomposed by high heat to turn into ammonia, which raises a plurality of conductivity and becomes higher than the reference value.

이렇게 복수의 전도도가 상승하여 기준치보다 높아지면, 상기 분석장치(70)는 제1우회수밸브(31)를 닫고 유입수밸브(11)와 처리수밸브(21)를 열어서 정밀여과기(60)를 통해 유입되는 복수가 복수탈염장치(80)를 통과하도록 한다. 이에 따라 복수 중의 암모니아가 제거되어 전도도가 기준치 이하로 낮아지게 된다.
When the plurality of conductivity is increased and higher than the reference value, the analysis device 70 closes the first bypass water valve 31 and opens the inlet valve 11 and the treated water valve 21 through the precision filter 60. Inflow of the plurality of passes through the plurality of desalination unit (80). As a result, the ammonia in the plurality is removed and the conductivity is lowered below the reference value.

이와 같이, 복수탈염시스템의 우회운전이 정지되고 복수탈염장치(80)를 통해 복수가 처리되면서 이온교환수지에 의해 제거된 하이드라진과 에탄올아민 등과 같은 약품들을 복수탈염장치(80)의 후단에서 보충하여 계통수의 수질이 정적하도록 관리한다. 또, 우회운전 중에도 복수탈염장치(80)를 통과하는 약 5%의 복수에 포함되어 이온교환수지에의해 제거된 에탄올아민 등과 같은 약품들도 복수탈염장치의 후단에서 보충된다.
In this way, while the bypass operation of the multiple desalination system is stopped and the plurality is processed through the multiple desalination apparatus 80, chemicals such as hydrazine and ethanolamine removed by ion exchange resin are replenished at the rear end of the multiple desalination apparatus 80. Manage the water quality of the plant water to be static. In addition, chemicals such as ethanolamine and the like, which are contained in the plurality of about 5% passing through the plurality of desalination apparatus 80 and removed by the ion exchange resin, are also replenished at the rear end of the plurality of desalination apparatus even during the bypass operation.

위와 같이, 본 발명에서 유입되는 복수의 수질에 상관없이 항상 복수탈염장치를 통과하여 처리되는 복수의 량은 약 5%로, 이렇게 처리되는 복수의 유속은 3-10m/h 로 하는 것이 바람직하다. 복수탈염장치를 통과하는 유속이 너무 느리면 이온교환수지에 교환된 이온들이 역으로 배출되어 처리수를 악화시킨다.
As described above, irrespective of the plurality of water inflows in the present invention, the plurality of amounts processed through the plurality of desalination apparatuses is always about 5%, and the plurality of flow rates thus treated is preferably 3-10 m / h. If the flow rate through the desalination apparatus is too slow, the ions exchanged in the ion exchange resin are discharged back, worsening the treated water.

한편, 통과유속이 빨라지면 통과유량이 많아지고, 약품 사용량이 많아지며, 이온교환수지의 재생이 빈번하게 되고, 빈번한 재생으로 폐수량도 증가하게 되며, 복수탈염장치 후단에서 주입하는 에탄올아민, 하이드라진과 같은 약품량도 증가하게 되어 운전비용이 증가하게 된다.
On the other hand, the faster the flow rate, the higher the flow rate, the more the amount of chemicals used, the more frequently the regeneration of the ion exchange resin, the more the waste water volume increases due to the frequent regeneration, and the ethanolamine, hydrazine and The same drug volume will also increase, increasing operating costs.

위에서 설명한 바와 같이, 본 발명은 제2유입수우회밸브(41)와 처리수우회밸브(51)가 항상 열려 있도록 하여 분석장치에 의한 운전절차에 우선하여 정밀여과기(60)를 통과하는 복수 중 약 5%의 소량의 복수가 항상 복수탈염장치(80)를 통과하면서 처리되도록 되어 있다.

따라서 복수탈염장치의 이온교환수지층에서 교환된 이온들이 누출되어 누출된 이온을 포함한 물을 버리고 운전해야 하는 일이 발생하지 아니하므로, 응축기에서 해수가 누수되어 복수의 전도도가 긴급하게 올라가 제1우회밸브(31)가 잠기고, 유입수밸브(11)와 처리수밸브(21)가 급격하게 열려 오염된 복수가 복수탈염장치로 유입되더라도 긴급 처리가 가능하여 계통수의 오염을 방지할 수 있다.
Therefore, since the exchanged ions leak out of the ion exchange resin layer of the multiple desalination device, it is not necessary to throw away the water containing the leaked ions and operate. Therefore, seawater leaks from the condenser and the plurality of conductivity is urgently raised to bypass the first.
