Description

연근해 해양플랜트용 냉각탑 기반의 냉각시스템 {Cooling System based on Cooling Water Tower for Nearshore Floating Plan}Cooling System based on Cooling Water Tower for Nearshore Floating Plan}

본 발명은 해양플랜트의 냉각에 관한 것으로서, 보다 구체적으로는 연근해에 설치되는 부유식 플랜트에서 공랭식 냉각기(Air Cooler)를 대신하여 수냉식 냉각탑을 적용하는 연근해 해양플랜트용 냉각탑 기반의 냉각시스템에 관한 것이다.The present invention relates to cooling of an offshore plant, and more particularly, to a cooling tower-based cooling system for an offshore offshore plant in which a water-cooled cooling tower is applied instead of an air cooler in a floating plant installed in the offshore.

부유식 생산 설비 플랜트(Floating Plant)는 생산 과정 중 발생되는 열처리를 위해 대량의 냉각수를 필요로 하며, 이는 해수를 이용한 열 교환 과정을 거쳐 냉각 및 가열된 해수는 선외 배출된다.Floating production plant (Floating Plant) requires a large amount of cooling water for heat treatment generated during the production process, which goes through a heat exchange process using seawater, and the cooled and heated seawater is discharged overboard.

연근해(Nearshore)에 설치되는 부유식 생산 설비의 경우, 아래와 같은 문제로 해수를 이용한 냉각시스템의 설치가 불가능한 경우가 있다.In the case of floating production facilities installed in nearshore, it is sometimes impossible to install a cooling system using seawater due to the following problems.

일 예로, 설치된 지역의 수심이 얕은 경우다. 이 경우, 대량의 해수를 흡입하는 과정에서 토사 및 이물질의 유입 등으로 인한 냉각계통 고장의 문제와 더불어 냉각 해수 품질의 문제를 유발하여 해수를 이용한 수냉이 불가하다.For example, the water depth of the installed area is shallow. In this case, water cooling using seawater is impossible as it causes a problem of cooling system failure due to the inflow of soil and foreign substances in the process of sucking a large amount of seawater, as well as a problem of the quality of the cooling seawater.

다른 예로서, 해당 설치 지역의 환경 규범에 따라 배출 해수 온도 상승이 엄격히 규제되거나 해수의 배출이 허용되지 않는 경우다. 이 경우, 그 어떤 조건에도 해수를 사용한 냉각 시스템을 구축하는 것이 불가하다.Another example is when the temperature rise of the discharged seawater is strictly regulated or the discharge of seawater is not permitted according to the environmental norms of the installation area. In this case, it is impossible to construct a cooling system using seawater under any conditions.

상기와 같은 사유로 연근해에 설치되는 부유식 생산설비는 공랭식 핀튜브 냉각탑(Air Cooler 또는 Dry Cooling Tower)를 적용하는 경우가 많은데, 공랭식 냉각탑은 수냉식 대비 낮은 열 전달효율로 인해 필요한 전열면적이 매우 커서 많은 수량의 공랭형 냉각탑을 설치하므로 단가 상승의 주된 요인이 된다. 또한 전열 면적만큼 넓은 설치 면적을 필요로 하여 한정된 설치 면적이라는 해상 플랜트의 조건상 배치가 매우 어려워 대개의 경우 플랜트 최상부 면적의 대부분에 추가 층을 개설하는 방식으로 공랭형 냉각탑 설치에 할애하게 된다.For the above reasons, floating production facilities installed in coastal waters often use an air-cooled fin tube cooling tower (Air Cooler or Dry Cooling Tower). Since a large number of air-cooled cooling towers are installed, it is a major factor in unit price increase. In addition, it is very difficult to arrange an offshore plant due to the limited installation area as it requires a large installation area as large as the heat transfer area, so in most cases, an additional layer is opened in most of the top area of the plant to install an air-cooled cooling tower.

이에, 수냉식 냉각 방식을 적용하기 위해 참조할 수 있는 선행기술문헌을 살피면 하기의 한국 공개특허공보 제2011-0054546호, 한국 등록특허공보 제0375689호 등의 선행특허가 발견된다.Accordingly, when looking at the prior art literature that can be referred to in order to apply the water-cooled cooling method, prior patents such as the following Korean Patent Publication No. 2011-0054546 and Korean Patent No. 0375689 are found.

그러나, 전자의 선행특허는 연근해 부유식 생산 설비에 적용하기 적합하지 않고, 후자의 선행특허는 연근해 부유식 생산 설비에 적용하기 위한 구조 개선을 필요로 한다.However, the former prior patent is not suitable for application to offshore floating production equipment, and the latter prior patent requires structural improvement for application to offshore floating production equipment.

이하, 첨부된 도면에 의거하여 본 발명의 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail based on the accompanying drawings.

본 발명은 연근해 해양플랜트의 생산모듈(10)을 냉각하는 시스템에 관하여 제안한다. 도 1은 에어쿨러(15)를 사용한 해양플랜트용 냉각시스템으로서 생산모듈(10)의 상측으로 상당히 넓은 공간이 요구된다. 도 2는 습식 냉각탑을 적용한 육상플랜트용 냉각시스템이고, 도 3은 밀폐형 냉각탑을 사용한 육상플랜트용 냉각시스템이다. 상기 어느 경우에나 전술한 이유로 연근해(Nearshore)에 설치되는 부유식 생산 설비에 탑재된 생산모듈(10)의 냉각에 적용하기 적합하지 않다. The present invention proposes with respect to a system for cooling the production module 10 of the offshore offshore plant. 1 shows a cooling system for an offshore plant using an air cooler 15, which requires a fairly large space above the production module 10. As shown in FIG. 2 is a cooling system for an onshore plant to which a wet cooling tower is applied, and FIG. 3 is a cooling system for an onshore plant using a closed cooling tower. In either case, it is not suitable for cooling the production module 10 mounted on a floating production facility installed in a nearshore for the above-mentioned reasons.

본 발명에 따른 냉각탑(20)은 분배기(24)와 집수조(26)를 구비하는 구조이다. 냉각탑(20)은 선폭의 중앙에 파이프랙을 이용하여 고정되고, 내부에 분배기(24)와 집수조(26)를 상하로 이격하여 수용한다. 냉각탑(20)의 기본적인 구성은 도 2 및 도 3에 나타내는 것처럼, 분배기(24), 집수조(26) 외에 고온관(21), 저온관(22), 순환수관(23), 송풍기(27) 등을 선택적으로 포함할 수 있다.The cooling tower 20 according to the present invention has a structure including a distributor 24 and a water collecting tank 26 . The cooling tower 20 is fixed using a pipe rack in the center of the line width, and the distributor 24 and the water collecting tank 26 are vertically spaced apart and accommodated therein. The basic configuration of the cooling tower 20 is, as shown in FIGS. 2 and 3, a high-temperature pipe 21, a low-temperature pipe 22, a circulation water pipe 23, a blower 27, etc. in addition to the distributor 24 and the water collecting tank 26. may optionally be included.

또한, 본 발명에 따르면 냉각수 공급수단(30)이 상기 생산모듈(10) 또는 냉각탑(20)에 냉각수 저장조(34)를 연결하여 생산모듈(10)의 냉각을 유발한다. 해양구조물인 해양플랜트도 습식 냉각탑 (Open Circuit Cooling Tower) 또는 밀폐형 냉각탑 (Closed Circuit Cooling Tower)을 기반으로 하는 냉각시스템을 적용하여 생산모듈(10)의 냉각을 유발할 수 있다. 다만 냉각시스템 및 냉각 매질로 해수를 사용 불가한 경우가 많으므로 구조적 개량이 수반되어야 한다.In addition, according to the present invention, the cooling water supply means 30 connects the cooling water storage tank 34 to the production module 10 or the cooling tower 20 to cause cooling of the production module 10 . An offshore plant, which is an offshore structure, may also cause cooling of the production module 10 by applying a cooling system based on a wet cooling tower (Open Circuit Cooling Tower) or a closed circuit cooling tower (Closed Circuit Cooling Tower). However, as there are many cases where seawater cannot be used as a cooling system and cooling medium, structural improvement must be accompanied.

본 발명의 냉각시스템에 적용되는 냉각수 저장조(34)는 중력 낙하 또는 펌프 이송된 냉각수를 저장하고 생산모듈(10) 또는 냉각탑(20)으로 토출하는 하는 선내 저장부 기능을 수행한다.The cooling water storage tank 34 applied to the cooling system of the present invention performs a function of an inboard storage unit for storing cooling water that has been dropped or pumped by gravity and discharged to the production module 10 or the cooling tower 20 .

본 발명의 제1실시예로서, 상기 냉각수 저장조(34)는 집수조(26)에서 분배기(24)에 이르는 순환경로에 설치되고, 순환경로에 연결된 생산모듈(10)을 거쳐 분배기(24)로 냉각수를 공급하는 것을 특징으로 한다. 도 4의 습식 냉각탑(20)은 냉각수와 공기가 직접 접촉하여 대기의 습구 온도에 따른 냉각수의 증발 잠열을 이용하여 열교환하는 형태이다. 냉각탑(20), 냉각수 저장조(34), 생산모듈(10)이 하나의 냉각사이클로 이루어진다. 냉각수 저장조(34)에서 생산모듈(10)에 이르는 급수관(31) 상에는 펌프(36)를 설치하는 것이 좋다. 다수의 생산모듈(10)은 냉각탑(20)에 병렬적 배관으로 연결될 수 있다.As a first embodiment of the present invention, the cooling water storage tank 34 is installed in a circulation path from the water collecting tank 26 to the distributor 24, and the cooling water is supplied to the distributor 24 through the production module 10 connected to the circulation path. It is characterized by supplying The wet cooling tower 20 of FIG. 4 has a form in which cooling water and air directly contact and exchange heat using latent heat of evaporation of the cooling water according to the wet-bulb temperature of the atmosphere. The cooling tower 20, the cooling water storage tank 34, and the production module 10 consist of one cooling cycle. It is preferable to install the pump 36 on the water supply pipe 31 from the cooling water storage tank 34 to the production module 10 . A plurality of production modules 10 may be connected to the cooling tower 20 by a parallel pipe.

미설명 부호 28은 필러로서 분배기(24)에서 집수조(26)로 낙하되는 냉각수 및 송풍기(27)에 의한 냉각공기 간의 열교환을 촉진한다.Reference numeral 28, as a filler, promotes heat exchange between the cooling water falling from the distributor 24 to the water collecting tank 26 and the cooling air by the blower 27 .

본 발명의 제2실시예로서, 상기 냉각수 저장조(34)는 집수조(26)에서 분배기(24)에 이르는 순환경로에 설치되고, 상기 생산모듈(10)은 냉각탑(20)에 수용되는 열교환기(25)에 연결되는 것을 특징으로 한다. 도 5의 밀폐형 냉각탑은 폐쇄회로를 순환하는 냉각수에 살포수를 뿌려 냉각하고 가열된 살포수는 공기와 직접 접촉시켜 열교환하는 형태이다. 냉각탑(20)과 냉각수 저장조(34)가 일측 냉각사이클로 이루어지고, 생산모듈(10)과 열교환기(25)가 타측 냉각사이클로 이루어진다. 다수의 생산모듈(10)은 열교환기(25)에 병렬적 배관으로 연결된다. 냉각수 저장조(34)에서 생산모듈(10)에 이르는 급수관(31) 상에는 펌프(36)가 설치된다.As a second embodiment of the present invention, the cooling water storage tank 34 is installed in a circulation path from the water collecting tank 26 to the distributor 24, and the production module 10 is a heat exchanger accommodated in the cooling tower 20 ( 25) is connected. In the closed cooling tower of FIG. 5, spray water is sprayed on cooling water circulating in a closed circuit for cooling, and the heated spray water is in direct contact with air to exchange heat. The cooling tower 20 and the cooling water storage tank 34 consist of a cooling cycle on one side, and the production module 10 and the heat exchanger 25 consist of a cooling cycle on the other side. A plurality of production modules (10) are connected to the heat exchanger (25) in parallel piping. A pump 36 is installed on the water supply pipe 31 from the cooling water storage tank 34 to the production module 10 .

이러한 습식 또는 밀폐형 냉각탑(20)을 적용한 냉각시스템을 기반으로 하면 습구온도를 통한방열로 건구온도를 통해 방열하는 공랭형 냉각탑보다 열 전달효율이 매우 우수하며, 그에 따라 초기 투자 비용(설치 면적 포함)과 운전 비용이 많게는 1/6 로 절약된다.Based on the cooling system to which such a wet or sealed cooling tower 20 is applied, heat transfer efficiency is much better than that of an air-cooled cooling tower that dissipates heat through dry-bulb temperature by dissipating heat through wet-bulb temperature, and accordingly, initial investment cost (including installation area) and operating costs are saved by as much as 1/6.

본 발명의 세부 구성으로서, 상기 냉각수 저장조(34)는 냉각탑(20)의 하측에 단열 구조로 형성되어 냉각수 또는 살포수를 저장하는 것을 특징으로 한다. 냉각탑(20)과 냉각수 저장조(34)를 연결하는 회수관(32)은 상대적으로 직경이 크면서 짧은 경로로 배치되는 것이 좋다. 냉각수 저장조(34)는 해상 조건을 고려하여 타공판 배치 및 배수구 처리한 구조로 형성되고 습식 또는 밀폐형 냉각탑(20)과 긴밀하게 연계된다. 냉각수 저장조(34)는 습식 냉각탑이 적용된 경우 냉각수를 생산모듈(10)로 토출하고 밀폐형 냉각탑이 적용된 경우 살포수를 냉각탑(20)으로 토출하는 관로와 펌프를 포함한다.As a detailed configuration of the present invention, the cooling water storage tank 34 is formed in a heat insulating structure on the lower side of the cooling tower 20 to store cooling water or spray water. It is preferable that the recovery pipe 32 connecting the cooling tower 20 and the cooling water storage tank 34 has a relatively large diameter and is arranged in a short path. The cooling water storage tank 34 is formed in a structure in which a perforated plate is disposed and a drainage hole is processed in consideration of sea conditions, and is closely connected with the wet or sealed cooling tower 20 . The cooling water storage tank 34 includes a pipe and a pump for discharging cooling water to the production module 10 when a wet cooling tower is applied and for discharging spray water to the cooling tower 20 when a closed cooling tower is applied.

한편, 도시에는 생략하나 냉각수 저장조(34)는 단열재로 감싸서 냉각수 또는 살포수의 온도 상승에 의한 냉각 효율 저하를 방지한다.On the other hand, although omitted in the drawings, the cooling water storage tank 34 is wrapped with an insulating material to prevent a decrease in cooling efficiency due to a temperature increase of the cooling water or the spraying water.

또한, 본 발명에 따르면 냉각수 보충수단이 상기 냉각수 공급수단(30)에 냉각수를 보충하도록 연결된다. 냉각수 보충수단은 제한된 구역 내 효율적으로 장비를 배치해야 하는 동시에 생산설비의 중량 증가를 최소화해야 하는 해양플랜트의 특성에 부합되어야 한다.In addition, according to the present invention, the cooling water replenishing means is connected to replenish the cooling water to the cooling water supply means (30). The cooling water replenishment means must conform to the characteristics of the offshore plant, which must efficiently arrange the equipment within a limited area and minimize the increase in the weight of the production facility.

본 발명의 세부 구성으로서, 상기 냉각수 보충수단은 조수기(40)에 의하여 생산된 청수로 냉각수 저장조(34)의 설정된 수위를 유지하는 것을 특징으로 한다. 냉각수 보충수단은 상황에 따라 육상에서 공급된 청수를 사용할 수 있으나 연근해의 상황 변화를 고려할 때 조수기(40)를 기본으로 하는 것이 바람직하다. 조수기(40)는 해수관(42)으로 유입된 해수를 청수로 전환하고, 청수관(44)을 통하여 청수를 냉각수 저장조(34)로 보내며, 처리 후의 해수는 배수관(46)을 통하여 선외로 배출한다. 청수를 해양플랜트에서 자체 공급하는 경우 역삼투 또는 저압증발식을 적용하되 저압증발식의 경우 해양플랜트의 폐열회수장치를 포함할 수 있다.As a detailed configuration of the present invention, the cooling water replenishment means maintains a set water level in the cooling water storage tank 34 with fresh water produced by the fresh water generator 40 . Fresh water supplied from the land may be used as the cooling water replenishment means depending on the situation, but it is preferable to use the fresh water generator 40 as a basis in consideration of the change in the situation in the coastal waters. The fresh water generator 40 converts the seawater introduced into the seawater pipe 42 into fresh water, sends the fresh water to the cooling water storage tank 34 through the fresh water pipe 44, and the seawater after treatment is discharged overboard through the drain pipe 46. discharge When fresh water is supplied by the offshore plant itself, reverse osmosis or low-pressure evaporation is applied, but in the case of low-pressure evaporation, the waste heat recovery device of the offshore plant may be included.

이때, 도시에는 생략하나 냉각수 저장조(34)에 수위센서를 설치하고 냉각수 보충수단을 제어하여 충분한 냉각수량이 유지되도록 한다.At this time, although not shown, a water level sensor is installed in the cooling water storage tank 34 and a cooling water replenishment means is controlled to maintain a sufficient amount of cooling water.

이에, 해양플랜트에 적용된 사례가 없고 육상의 플랜트에만 적용되었던 습식 또는 밀폐형 냉각탑을 해양 플랜트에 적용하여 배치 효율성 증대와 초기 투자 비용 감소를 도모할 수 있다.Accordingly, it is possible to increase the deployment efficiency and reduce the initial investment cost by applying the wet or sealed cooling tower, which has not been applied to an offshore plant and has been applied only to an onshore plant, to an offshore plant.
