Description

압력용기 연결형 원수분배 장치Pressure vessel connection type raw water distribution device
본 발명은 해수 역삼투 기술공정에 필요한 압력용기용 원수분배장치에 관한 것으로서, 더욱 상세하게는 중앙 주입식 압력용기에 용이하게 연결이 가능하면서 압력을 견딜 수 있는 압력용기 연결형 원수분배 장치에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raw water distributing apparatus for a pressure vessel required for a seawater reverse osmosis technology process, and more particularly, to a raw water distributing apparatus for a pressure vessel connection type that can easily be connected to a central injection type pressure vessel and can withstand pressure.
일반적으로, 해수는 고농도의 무기질 용액상태로 존재하고 있어 상수도로 이용하기에는 여러 가지 제약을 가지고 있다. 이를 해결하기 위하여, 다양한 해수의 담수화 공법이 제안되고 있다. 다양한 해수 담수화 공법 중, 해수 역삼투 공법에서는 수리학적 압력과 반투과성 막을 이용하여 저농도의 생산수를 얻어낸다. 이 과정에서 해수가 가지고 있는 화학적 삼투압 이상의 압력(예를 들면, 25bar 이상)이 사용되며 이를 견딜 수 있는 고압의 압력용기와 파이프라인이 이용된다.In general, seawater is present in a high concentration of inorganic solution, and has various limitations in using it as tap water. To solve this problem, various seawater desalination methods have been proposed. Among various seawater desalination methods, seawater reverse osmosis method uses hydraulic pressure and semi-permeable membrane to obtain low density production. During this process, pressure above the chemical osmotic pressure of seawater (for example, 25 bar or more) is used and high-pressure vessels and pipelines are used to withstand this.
해수담수화 플랜트는 고압의 조건에서 운전을 요하기 때문에 높은 에너지 소요량으로 인해 생산수 단가가 비교적 높다. 따라서 생산수 단가를 낮추기 위한 제막 기술향상으로 현재는 단일 막 면적에 따른 생산수량 증대가 가능한 고 플럭스 막 적용이 필요하다. 그러나 고 플럭스 막의 적용은 에너지 저감이라는 측면에서 장점이 있으나, 비교적 수질 악화 및 파울링 증대라는 단점이 존재한다. The seawater desalination plant requires high-pressure operation and therefore has a relatively high production cost due to high energy requirements. Therefore, it is necessary to apply high flux membrane which can increase the production quantity according to single membrane area. However, the application of the high flux membrane has advantages in terms of energy reduction, but there is a disadvantage of relatively high water loss and fouling increase.
기존의 해수 역 삼투 공법을 이용할 경우에는 다양한 막 성능 감소 문제가 발생한다. 그중 가장 주요한 원인으로 운전 시 발생하는 파울링(Fouling)에 의해서 수 투과도와, 염 제거율이 낮아지는 현상이 발생한다. 이를 해결하기 위해서는 막의 화학적, 물리적 세정작업이 필요하며 이 과정을 통해 비가역적인 막의 변형이 발생한다. 이를 해결하기 위해서는 주기적인 막 모듈의 교체가 필요하며, 소형 플랜트의 경우 유지 보수 관리에 큰 무리가 없지만 대형 플랜트의 경우, 막의 유지관리에 큰 비용이 발생한다.When using the existing seawater osmosis method, various membrane performance problems occur. Among them, the water permeability and the salt removal rate are lowered due to the fouling occurring during operation. In order to solve this problem, chemical and physical cleaning of the membrane is required, and irreversible membrane deformation occurs through this process. In order to solve this problem, it is necessary to replace the membrane module periodically. In the case of a small-sized plant, there is no problem in maintenance management. However, in the case of a large-
이러한 단점을 극복하기 위해 ISD(Initial Stage Design)등의 설계방식이 도입되었으나, 근본적인 해결책이 될 수는 없다.In order to overcome these disadvantages, design methods such as ISD (Initial Stage Design) have been introduced, but it can not be a fundamental solution.
해수 역삼투 공정에서의 생산을 이루는 기본 단위는 트레인으로 명명된다. 트레인은 고압 펌프, 압력용기, 막 모듈, 파이프라인으로 구성되어 있다. 압력용기의 설치는 압력용기 내부에 실제 수 투과가 발생하는 막 모듈로 구성되어 있다.The basic unit of production in the seawater reverse osmosis process is called the train. The train consists of high pressure pump, pressure vessel, membrane module and pipeline. The installation of the pressure vessel consists of a membrane module in which actual water permeation occurs inside the pressure vessel.
현재 사용되고 있는 압력용기의 대부분은 여러 막 모듈 제조사에 의해서 규격화된 원통형 지름 8인치 막 모듈에 적합하게 설계되어 있으며, 시장에 의해 규격화된 압력용기의 경우 모두 단방향의 유체흐름을 가지도록 설계되어 있다. 막 모듈의 유지보수에서는 그 편의성이 다른 무엇보다 중요하다. 8인치 막의 경우 성인남성이 도구를 사용하지 않고 설치 가능하지만, 트레인의 대형화 추세에 따라서 16인 치 막의 경우 막 모듈 교체용 장비가 필요할 만큼 유지보수에 문제점이 존재하고 있다.Most of the pressure vessels currently in use are designed for a cylindrical diameter 8 inch membrane module standardized by several membrane module manufacturers and are designed to have unidirectional fluid flow for all pressure vessels standardized by the market. The convenience of membrane module maintenance is more important than anything else. In the case of 8 inch membranes, it is possible for an adult male to install without using tools. However, due to the trend of increasing the size of the train, there is a maintenance problem in the case of a 16 inch membrane requiring equipment for membrane module replacement.
이를 개선하기 위해서 다양한 방식의 유체흐름을 유도하는 압력용기 설계가 제안되고 있는데, 그 중에 현재 개념적으로 제안되고 있는 중앙주입식 압력용기 설계 방식이 있다. 중앙 주입식 압력용기 설계란, 기존의 말단에서부터 말단으로 단방향의 유체흐름을 가지는 압력용기의 설계방식이 아닌 원수가 중압으로 주입되어 양 끝단 방향으로 진행해 나아가는 형태를 지니고 있다.To improve this, a pressure vessel design that induces fluid flow in various ways has been proposed. Among them, there is a central injection pressure vessel design method which is currently conceptually proposed. The central injection pressure vessel design has a form in which the raw water is injected at intermediate pressure rather than a design method of a pressure vessel having a unidirectional fluid flow from the end to the end, and proceeds in both end directions.
단방향으로 진행되는 고압의 원수의 흐름을 견디며 압력용기의 내부 움직임을 제한하기 위해서 막 모듈의 양 말단에는 고무 오링(O-ring)이 존재하고 있다. 일반적인 형태의 오링(O-ring)의 경우 막 모듈의 압력용기 내부 움직임이 제한되기 때문에 설치가 불가능하게 된다. 따라서 오링이 경사져 있는 형태를 유지하여 단 방향에 대해서는 움직임이 용의하나 반대 방향의 움직임에 대해서는 제한되도록 설계된다. 즉 막 모듈의 설치를 위해서는 단 방향 흐름 반대 방향에서 밀어 넣는 방식으로 설치된다.O-rings are present at both ends of the membrane module to withstand the flow of unidirectional high pressure raw water and to limit the internal movement of the pressure vessel. In the case of a typical O-ring, the movement of the membrane module inside the pressure vessel is restricted, making installation impossible. Thus, the O-ring is designed to be sloped so that it is designed to restrict movement in the single direction but restrict the movement in the opposite direction. In other words, for the installation of the membrane module, it is installed by pushing in the opposite direction of the unidirectional flow.
미국공개특허 US2010/0133183A에는 중앙 주입식 형태의 압력용기 설계방법이 제안되고 있다. 상기 선행 기술에 의하면 중앙 주입식 설계는 기존 설계에 비하여 에너지 소비량을 감소시킬 수 있으며 동시에 트레인에 필요한 실질적인 부지를 감소시킬 수 있다는 장점을 기술하고 있다. 그러나, 상기 선행 기술의 경우 현재 개념적인 특허의 형태로 존재하고 있으며 이를 실질적으로 실행에 옮긴 pilot plant나 실제 적용 사례가 존재하고 있지 않다. 이는 중앙 주입식 압력용기 설계가 가지고 있는 실질적인 플랜트 적용의 기술적 한계점을 가지고 있기 때문이다. U.S. Patent Publication No. US2010 / 0133183A proposes a pressure vessel design method in the form of a central injection type. According to the prior art, central injection type design has the advantage that it can reduce energy consumption compared to existing design and at the same time can reduce substantial site required for train. However, the above prior art exists in the form of a conceptual patent, and there is no pilot plant or practical application actually put into practice. This is because the central injection pressure vessel design has the technical limitations of practical plant applications.
특히, 상술한 바와 같이, 상용화 막 모듈의 O-ring은 경사진 구조로 구성되어 있어 단일 방향으로 막 모듈의 설치가 이루어져야 하는 바, 중앙주입식 설계방법에서는 이러한 단일 방향의 막 모듈의 설치가 적용되기 어렵다는 문제점이 있다. Particularly, as described above, since the O-ring of the commercialized membrane module is composed of a tilted structure, the membrane module should be installed in a single direction. In the central injection type design method, the installation of such a single- There is a problem that it is difficult.
상술한 바와 같이, 중앙 주입식 압력용기를 현실화하여 설치하기 위해서는 막 모듈의 유지보수 관리에 편의성에 문제가 발생하게 된다. 현재의 압력용기 설계를 이용할 경우 막 모듈의 설치는 가능하지만, 유지보수 관리를 위해서 막 모듈을 제거할 수 없는 구조를 가지고 있으며, 따라서 중앙 주입식 압력용기의 제조설치를 위해서는 현재 적용되고 있는 압력용기, 막 모듈의 새로운 설계가 필요하고 현재 상용화된 제품을 이용하여 중앙 주입식 설계가 가능하게 하는 장비가 필요하다.As described above, in order to realize the central injection type pressure vessel as a realization, there arises a problem in convenience for maintenance of the membrane module. The membrane module can be installed by using the current pressure vessel design, but the membrane module can not be removed for maintenance management. Therefore, in order to manufacture and install the central injection pressure vessel, There is a need for a new membrane module design and equipment that enables centralized implant design using currently commercialized products.
또한, 십자 관을 이용할 경우 파이프에 걸리는 높은 고압에 의해서 누수가 발생할 가능성이 높으며 안정성에 있어서 문제가 발생하므로, 중앙 주입식 압력용기를 제조하기 위해서는 압력을 온전하게 견딜 수 있으며 원수를 분배할 수 있는 장치가 중간에 필요하다.In addition, when a crucible is used, there is a high possibility of leaking due to a high pressure applied to the pipe, and there is a problem in stability. Therefore, in order to manufacture a central injection type pressure vessel, In the middle.
본 발명은 상술한 종래기술의 문제점을 해결하고자 하는 것으로서, 본 발명의 목적은 막 모듈의 유지관리가 간편하고, 유지보수 관리를 위하여 막모듈을 용이하게 제거 교체할 수 있는 중앙주입식 압력용기용 원수분배장치를 제공하는 것이다. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the prior art, and it is an object of the present invention to provide a membrane module in which a membrane module can be easily maintained, And to provide a dispensing device.
본 발명의 다른 목적은 고압에서도 안전하게 압력을 견딜 수 있는 중앙주입식 압력용기용 연결형 원수분배장치를 제공하는 것이다. It is another object of the present invention to provide a connection type raw water distribution apparatus for a central injection type pressure vessel which can safely withstand pressure even under high pressure.
상술한 목적을 달성하기 위하여, 본 발명에 의한 압력용기 연결형 원수분배 장치는, 중앙 주입식 압력용기에 연결되는 원수분배장치로서, 양측의 압력용기 사이에 배치되며 중앙부분에 주입되는 원수를 양측의 압력용기에 공급하며 내측에 복수의 막 모듈이 기밀하게 수용되는 본체부와, 상기 본체부의 중앙부분에 설치되어 원수가 주입되는 원수주입부와, 상기 원수주입부에 직교하는 방향에서 상기 본체부의 양측 끝단을 폐쇄하며 상기 본체부에 착탈 가능하게 설치되는 캡과, 상기 캡을 관통하여 설치되며 상기 원수주입부로부터 주입되는 원수를 상기 압력용기에 공급하는 원수공급파이프를 구비하는 것을 특징으로 한다. In order to achieve the above object, the present invention provides a raw water distributing device connected to a central injection type pressure vessel, wherein raw water to be injected into a central portion is disposed between pressure vessels on both sides, A raw water supply portion provided at a central portion of the main body portion to supply raw water, and a plurality of membrane modules provided at both ends of the main body portion in a direction orthogonal to the raw water injection portion, And a raw water supply pipe installed to penetrate through the cap and supplying raw water to the pressure vessel from the raw water injection unit.
상술한 구성을 가지는 본 발명의 원수분배장치에 의하면, 현재 기술로는 실질 적용이 불가한 중앙 주입식 설계를 현재 존재하고 있는 장비를 이용하여 설계 가능하며, 중앙 주입식 설계 방식을 적용할 수 있어서 에너지 소비량과 설치 공간적 차이에 의해서 기존의 재래식 역 삼투 트레인 설계 방식에 비해서 소요 비용을 절감할 수 있다. According to the raw water distribution apparatus of the present invention having the above-described configuration, it is possible to design the central injection type design, which can not be practically applied in the present technology, by using existing equipment, and the central injection type design method can be applied, It is possible to reduce the cost compared to the conventional reverse osmosis train design method.
또한, 경사져 배치되되 본체부 내부에서 일 방향으로의 움직임이 가능한 오링을 적용함으로써, 단일방향의 오링을 적용하면서도 중앙 주입식 설계방식을 이용할 수 있다. Further, by applying an O-ring which is inclined and capable of moving in one direction inside the body portion, a central injection type designing method can be used while applying a single directional O-ring.
또한, 양측의 압력용기로부터 원수분배장치를 용이하게 체결 및 해체할 수 있을 뿐만 아니라, 본체부 내의 막 모듈의 유지관리가 간편하고, 유지보수 관리를 위하여 막모듈을 용이하게 제거 교체할 수 있고, 단순히 십자관을 이용하는 것이 아니라, 원수주입부와 원수공급파이프를 가지는 본체부의 구성에 의해 고압에서도 안전하게 압력을 견딜 수 있다. In addition, it is possible not only to easily fasten and dismantle the raw water distribution device from the pressure vessels on both sides, but also to maintenance of the membrane module in the main body part is easy and the membrane module can be easily removed and replaced for maintenance management, It is possible to withstand the pressure safely even at a high pressure by the structure of the body portion having the raw water injection portion and the raw water supply pipe instead of simply using the crucible tube.
또한, 원수 유입관의 관경이 증가하여 유입간의 손실수두가 줄어들어 에너지 소비량을 줄일 수 있고, 양 단의 장치를 이용하여 유입수의 운전 조건을 달리할 수 있으며, 이를 이용하여 트레인 내에서 다양한 성능의 막 모듈을 적용하여 최적화된 운전을 가능하다.In addition, since the diameter of the raw water inflow pipe is increased to reduce the loss head between inflows, it is possible to reduce the energy consumption, and the operation conditions of the inflow water can be changed by using the apparatus of both ends.

도 1 내지 도 7에 나타낸 바와 같이, 본 발명에 의한 압력용기 연결형 원수분배 장치는 중앙 주입식 압력용기에 연결되는 원수분배장치로서, 상용화되어 이용되고 있는 부품을 이용하여 중앙 주입식 설계의 현실화가 가능할 수 있도록 원수를 분배할 수 있는 장치에 관한 것이다. As shown in Figs. 1 to 7, the raw water distributing device of the present invention is a raw water distributing device connected to a central injection type pressure vessel, and it is possible to realize a central injection type design by using components that are commercially used The present invention relates to a device capable of distributing raw water.
본 발명에 의한 원수분배장치를 제조 및 설계하기 위해서는 크게 3가지의 구체적인 제한사항을 해결할 수 있는 특징을 가지고 있어야 하는데, 이는 역삼투 공정에서 필요한 고압에 대한 내구성과, 각종 내화학성 재질을 이용해야 하며, 탈부착이 용이하며 누수가 발생하지 않는 특징을 가지고 있어야 한다. In order to manufacture and design the raw water dispensing apparatus according to the present invention, three specific limitations must be solved. It is necessary to use the durability against the high pressure required in the reverse osmosis process and various chemical resistant materials , It should be easy to attach and detach and do not leak.
중앙 주입식 압력용기의 설계의 요지는 단일 압력용기에서 원수가 두 흐름으로 나뉘어져 양 말단 방향으로 진행되는데, 이 과정에서 발생하는 공간 부지의 절감 효과와 운영 에너지 소비량이 감소되는 효과를 얻을 수 있다. 그러나, 종래의 중앙 주입식 압력용기는 상업화된 장비를 이용하여 설계할 수 없는 기술적 제한점이 존재하는 바, 본 발명에서는 이러한 문제점을 개선하기 위해서 원수 분배 장치를 두어 기존의 압력용기와 막 모듈을 이용한 중앙 주입식 설계를 하는 것에 그 특징이 있다. The main point of the design of the central injection type pressure vessel is that the raw water is divided into two flows in a single pressure vessel and proceeds in both end directions. In this process, the space and the energy consumption are reduced. However, in the conventional central injection type pressure vessel, there are technical limitations that can not be designed by using commercialized equipment. In order to solve such a problem, in the present invention, a raw water distribution device is provided, It is characterized by the injection type design.
즉 본 발명에 의한 중앙 주입식 설계는 양 단에 각각 독립적인 압력용기가 존재하며 이 사이를 연결하는 원수 분배 장치가 존재하게 되며, 상기 원수 분배장치는 각각의 압력용기를 연결하여 하나의 생산단위로 결합시키게 된다. That is, in the central injection type design according to the present invention, there are independent pressure vessels at both ends, and there is a raw water distributing device for connecting the pressure vessels, and the raw water distributing device connects each pressure vessel to one production unit Respectively.
본 발명에 의한 원수분배장치(1)는 본체부(10)와, 원수주입부(20)와, 캡(30)과, 원수공급파이프(40)를 포함하여 구성된다. The raw water distribution apparatus 1 according to the present invention comprises a main body 10, a raw water injection unit 20, a cap 30, and a raw water supply pipe 40.
상기 본체부(10)는 양측의 2개의 압력용기(2) 사이에 배치된다. 상기 본체부(10)는 대략 원통형 형상으로 형성되며, 중앙부분에는 원수주입부(20)가 연결된다. 상기 본체부(10)는 상기 원수주입부(20)를 통해 주입되는 원수를 양측의 상기 압력용기(2)에 각각 공급하도록 구성된다. 본 실시예에 있어서, 상기 본체부(10)의 몸체(11)는 내화학성, 내식성 성질을 가지고 있는 FRP재질로 형성되는 것을 예로 한다. The main body 10 is disposed between two pressure vessels 2 on both sides. The main body 10 is formed in a substantially cylindrical shape, and a raw water injection part 20 is connected to the center part. The main body 10 is configured to supply the raw water injected through the raw water injection unit 20 to the pressure vessel 2 on both sides. In the present embodiment, the body 11 of the main body 10 is formed of FRP material having chemical resistance and corrosion resistance.
상기 본체부(10)의 내측에는 복수의 막 모듈(50)이 수용된다. 상기 막 모듈(50)은 필요에 따라 복수 개가 상기 본체부의 내측에 수용될 수 있으며, 오링(O-ring; 60)을 통해 상기 본체부의 내면과 상기 막 모듈의 외주면과의 사이가 기밀하게 밀봉된다. A plurality of membrane modules (50) are housed inside the main body (10). A plurality of the membrane modules 50 may be housed inside the body portion if necessary, and an airtight seal is formed between the inner surface of the body portion and the outer peripheral surface of the membrane module through an O-ring 60 .
상기 오링(60)은 상기 막 모듈과 상기 본체부와의 사이에서 움직임이 가능하도록 배치될 수 있다. 도 8에 나타낸 바와 같이, 상기 오링(60)은 상기 본체부에 공급되는 원수의 흐름방향에 대하여 경사져 배치되어 일방향에 대해서는 움직임이 가능하지만 반대방향의 움직임에 대하여는 제한되도록 구성된다. 즉, 상기 오링(60)은 유동하는 상기 원수의 압력에 의해 원수흐름방향에 대하여 직교하도록 거동하여 상기 막모듈과 상기 본체부 사이를 기밀하게 밀봉한다. 경사져 배치되되 본체부 내부에서 일 방향으로의 움직임이 가능한 오링을 적용함으로써, 단일방향의 오링을 적용하면서도 중앙 주입식 설계방식을 이용할 수 있다. The O-ring 60 may be arranged to be movable between the membrane module and the main body. As shown in FIG. 8, the O-ring 60 is disposed obliquely with respect to the flow direction of the raw water supplied to the main body so as to be movable in one direction but restricted in the opposite direction. That is, the O-ring 60 acts to be orthogonal to the flow direction of the raw water by the pressure of the raw water flowing to hermetically seal the membrane module and the main body part. By applying an o-ring that is inclined and capable of moving in one direction inside the body portion, a central injection type designing method can be used while applying a single directional O-ring.

In order to secure the safety of the vertical pressure load generated in this process, the body portion of the portion where the raw water injection portion 20 is formed is thicker than the other portions. That is, the main body 10 is configured to form a reinforcing portion 12 having a diameter larger than the diameter of the body 11 of the main body portion at a portion where the raw water injecting portion 20 passes through the main body.
상기 본체부(10)의 양끝단에는 캡(30)이 설치된다. 상기 캡(30)은 상기 원수주입부에 직교하는 방향에서 상기 본체부의 양측 끝단을 폐쇄하도록 구성되며, 상기 본체부(10)에 착탈 가능하게 설치된다. 착탈가능한 상기 캡과 후술하는 원수공급파이프의 커플러에 의해 양측의 압력용기로부터 원수분배장치를 용이하게 체결 및 해체할 수 있을 뿐만 아니라, 본체부 내의 막 모듈의 유지관리가 간편하고, 유지보수 관리를 위하여 막모듈을 용이하게 제거 교체할 수 있다. At both ends of the main body 10, a cap 30 is installed. The cap 30 is configured to close both ends of the main body unit in a direction orthogonal to the raw water injection unit, and is detachably installed in the main body unit 10. [ It is possible to easily fasten and dismantle the raw water distributing device from the pressure vessels on both sides by the detachable cap and the coupler of the raw water supply pipe which will be described later as well as maintenance of the membrane module in the main body portion is easy, The membrane module can be easily removed and replaced.
