축열조 루프 시공방법{Heat storaging tank roof form of construction work}[0001] The present invention relates to a heat storage tank roof construction method,

본 발명은 축열조에 관한 것으로서, 좀더 상세하게는 축열조를 이루는 측벽으로부터 상부에 시공되는 루프의 시공방법을 개선하여 축열조 내부의 측벽과 루프의 경계지점(Edge part)에서 주로 부식성 가스에 의해 진행될 수 있는 산화부식을 최대한 방지시켜 축열조의 운영에 따른 수명을 대폭 연장할 수 있도록 한 축열조 루프 시공방법에 관한 것이다.
[0001] The present invention relates to a heat storage tank, and more particularly, to a method of constructing a loop constructed from a sidewall forming a heat storage tank and improving the construction method of the loop, which can be carried out mainly by a corrosive gas at an edge part of a sidewall and a loop inside the heat storage tank The present invention relates to a method of constructing a thermal storage tank loop that can greatly prevent oxidation corrosion and thereby prolong the service life of a thermal storage tank.

일반적으로 축열조는 냉난방 장치로부터 생산되는 냉,온열을 저장하고 그 저장된 냉,온열을 상기 냉난방 장소에 공급하게 하는 역할을 한다.Generally, the heat storage tank stores the cold and warm produced by the heating and cooling apparatus and supplies the stored cold and warm heat to the cooling and heating place.

냉온열 축열조는 필요에 따라 사용되지만 냉난방 장치로부터의 냉,온열을 상기 냉난방 장소에 중단없이 지속적으로 공급할 수 있는 장점과 심야전기를 를 이용 경제적인 냉,난방이 가능하므로 인해 근래에는 축열조가 냉난방 장치의 한 구성요소로 사용되고 있는 실정이다. Although the cold / hot heat storage tank is used as needed, it is advantageous in that the cooling / heating from the cooling / heating unit can be continuously supplied to the cooling / heating place without interruption, and the cooling / And the like.

이와 같은 냉,온열 축열조는 내부에 상기 냉난방 장치로부터 생산된 냉,온열을 저장하고, 그 저장된 냉,온열을 상기 냉난방 장소에 공급하게 하는 순환매체를 수용하고, 또한 상기 냉난방 장치와 연결되는 열교환부가 내부에 시설되어 있기 때문에, 상기 순환 매체가 상기 열교환부를 통해 그 열교환부를 순환하는 상기 냉난방 장치로부터의 냉,온열을 갖는 순환매체와의 열교환으로 냉,온열을 축열하도록 되어 있는바, 이와 같이 냉,온열을 축열한 순환매체는 냉난방 장소를 순환하며 그 축열한 냉,온열을 방출하여 상기 냉난방 장소에 대한 냉난방을 수행하게 되는 것이다.The cold / hot thermal storage tank stores therein the cold / hot heat generated from the cooling / heating unit, and receives the circulating medium for supplying the stored cold / hot heat to the cooling / heating place, and the heat / The circulating medium is arranged to heat the coolant and the heat by the heat exchange with the circulating medium having the coolant and the heat from the cooling and heating apparatus circulating the heat exchanger through the heat exchanger, The circulating medium storing the heat circulates the cooling and heating place, discharges the stored heat and cold, and performs the cooling and heating for the heating and cooling place.

상기와 같은 축열조는 대형 원통형으로 시공되며, 이는 각각의 철판을 이용하여 내부탱크(이하, '내벽'이라 함) 및 철판 또는 콘크리트로서 시공되는 외부탱크(이하, '외벽'이라 함)를 제작하고, 내부탱크와 외부탱크 사이에 발포 폴리에틸렌 또는 가교 폴리에틸렌으로 형성된 단열재를 삽입하거나 발포시켜 충전시키는 단열구조로 되어 있다.The above-mentioned thermal storage tank is constructed in a large cylindrical shape, and each steel plate is used to manufacture an inner tank (hereinafter referred to as "inner wall") and an outer tank (hereinafter referred to as "outer wall" , And a heat insulating structure formed by inserting foamed polyethylene or crosslinked polyethylene or inserting foaming between the inner tank and the outer tank.

한편, 상기와 같은 종래의 축열조(100)는 첨부된 도 1에서와 같이 스틸로 이루어진 측벽(110)의 내벽(112) 및 내벽 상부에 스틸로 이루어진 루프(120)의 천장용 패널(122)이 용접되고, 그 외측에는 단열재인 폴리우레탄 폼(P)이 미도시된 거푸집 작업으로서 충전되고, 상기 폴리우레탄 폼(P)의 외측면에는 스틸로 이루어진 외장재(S)가 커버되는 형태로 시공이 이루어진다.1, a ceiling panel 122 of a roof 120 made of steel is provided on an inner wall 112 of a sidewall 110 and an inner wall of a steel sidewall 110, A polyurethane foam P which is a heat insulating material is filled as a molding work not shown and the outer surface of the polyurethane foam P is covered with a covering material S made of steel .

그러나, 상기와 같은 종래의 축열조는 온수가 채워지면 열 성층화에 의해 루프와 쉘의 상단으로 전달되어 고온의 온도상승은 물론, 온도상승은 공기 중의 질소와 산소의 화합으로 일산화탄소가 발생하고 이러한 일산화탄소는 축열조 내부의 상층부로 몰리며, 축열조의 상층부 구조물의 산화를 점차 진행시키게 된다.However, when the hot water is filled, the conventional thermal storage tank is transferred to the upper end of the loop and the shell by thermal stratification, so that not only the temperature of the hot water is raised but also the temperature is raised by the combination of nitrogen and oxygen in the air. It is pumped into the upper part of the inside of the heat storage tank, and the oxidation of the upper layer structure of the heat storage tank is gradually advanced.

대형 축열조의 경우 상기와 같은 점을 감안하여 축열조의 내벽은 스테인레스 스틸판을 50mm 두께로 제작되지만 부식성 가스에는 취약하기 때문에 특히 측벽으로부터의 루프가 시설된 상층부의 경계지점에서 부분 산화가 진행되어 심지어는 누수가 발생하는 2차 산화를 촉진한다.In the case of a large-scale heat storage tank, considering the above points, the inner wall of the heat storage tank is made of stainless steel plate to have a thickness of 50 mm, but is vulnerable to corrosive gas. Particular oxidation progresses at the boundary of the upper- It promotes secondary oxidation where leakage occurs.

상기와 같이 구조물의 산화가 이루어지게 됨은 특히 측벽을 이루는 셀의 상부와 루프가 연결되는 경계지점(A)에서 주로 산화가 이루어지며, 이러한 산화는 첨부된 도 1에서 발췌한 부분과 같이 진행되어 열손실이 발생하고, 한번 산화가 이루어진 축열조의 특정부위의 축열조가동의 운영특성상 운행정지가 어렵기 때문에 실질적으로 해당부분에 내구성을 보강하기 위한 차원에서 막대한 보수비와 함께 상당한 시간과 노력이 소요되는 문제점이 있다.
The oxidation of the structure is performed mainly at the boundary point A where the upper part of the cell forming the side wall and the loop are connected to each other. The oxidation progresses as shown in the attached part of FIG. 1, Because it is difficult to stop the operation due to the operation characteristics of the heat storage tank operation in the specific region of the heat storage tank where the oxidation occurs, it takes a considerable amount of time and effort in order to substantially enhance the durability of the relevant portion have.

본 발명은 상기와 같이 제반되는 종래의 문제점을 해결하기 위하여 발명한 것으로서, 그 목적은 축열조를 이루는 측벽으로부터 상부에 시공되는 루프의 시공방법을 개선하여 축열조 내부의 측벽과 루프의 경계지점에서 주로 부식성 가스에 의해 진행될 수 있는 산화부식을 최대한 방지시켜 축열조의 운영에 따른 수명을 대폭 연장할 수 있도록 한 축열조 루프 시공방법을 제공함에 있다.

이하, 본 발명을 첨부된 도 2 내지 도 7을 참조하여 더욱 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to FIGS. 2 to 7. FIG.

본 발명은, 원통형의 측벽(110) 상부를 막음 처리하는 축열조(100)의 루프(120) 시공방법은, 첨부된 도 3에서와 같이 스틸 소재의 내벽(112)을 이루는 측벽(110) 상부에 스틸 소재의 천장용 패널(122)을 용접한다.The method of constructing the loop 120 of the thermal storage tank 100 for clogging the upper portion of the cylindrical side wall 110 comprises the steps of forming a loop 120 on the upper side wall 110 of the steel material inner wall 112, The ceiling panel 122 of the steel material is welded.

상기와 같은 상태에서 측벽(110) 상면 가장자리에 띠 형태로 천장용 패널(122) 가장자리에는 일정간격을 두고 마감턱(130)을 용접한다.In this state, the edge 130 is welded to the edge of the ceiling panel 122 at a predetermined interval in the form of a strip at the upper edge of the side wall 110.

상기 마감턱(130)의 용접으로서 천장용 패널(122)의 가장자리로 공간부(101)가 형성된다.As the welding of the finishing jaw 130, the space portion 101 is formed at the edge of the ceiling panel 122.

또한, 상기 마감턱(130)의 내측면과 측벽(110)의 상면에 지지봉(132)을 등간격지게 용접하여 측벽(110)으로부터의 마감턱(130)의 용접부분을 보강하도록 한다.A support bar 132 is welded equally to the inner surface of the fin 130 and the upper surface of the side wall 110 to reinforce the welded portion of the fin 130 from the side wall 110.

상기와 같이 천장용 패널(122)의 상부로부터는 첨무된 도 4에서 도시한 바와 같이 폴리우레탄 폼(P1)을 발포하여 마감턱(130)의 상면까지 채워 1차 단열층을 형성시켜 준다.As shown in FIG. 4, the polyurethane foam P1 is foamed from the upper portion of the ceiling panel 122 to fill the upper surface of the finisher 130 to form a primary heat insulating layer.

상기 천장용 패널의 상부는 둥근 형태로 이루어져 있고, 마감턱의 형성으로서 1차 단열층을 이루는 폴리우레탄 폼은 상기 전창용 내벽의 둥근 형태와 같이 시공이 이루어진다.The upper part of the ceiling panel is formed in a round shape, and the polyurethane foam forming the primary heat insulating layer as the finishing step is formed like the round shape of the inner wall for the front window.

상기 마감턱(130)의 외측둘레로부터 폴리우레탄 폼(P1)의 가장자리를 포함하도록 도 5에서 도시한 바와 같이 알루미늄 소재의 플래싱(140)을 띠 형태로 덧대어 용접한다.As shown in FIG. 5, a flashing 140 made of an aluminum material is padded in a strip shape so as to include the edge of the polyurethane foam P1 from the outer periphery of the finishing step 130.

상기 플래싱(140)은 일정각도 절곡 형성한 것으로서 마감턱(130)의 외측면과 1차 단열층을 이루는 폴리우레탄 폼(P1)의 가장자리를 한번 더 보강하는 효과를 갖게 한다.The flashing 140 is bent at a predetermined angle and has the effect of reinforcing the edges of the polyurethane foam P1 forming the primary insulation layer and the outer surface of the finishing step 130 once more.

상기와 같이 1차 단열층 작업공정과 플래싱(140)의 부착작업이 이루어진 상태에서 폴리우레탄 폼(P1)과 플래싱(140) 외곽으로 덧씌우는 형태가 되도록 첨부된 도 6에서 도시한 바와 같이 폴리우레탄 폼(P2)을 발포하여 2차 단열층을 형성한다. 이때의 폴리우레탄 폼(P2)의 가장자리는 상기 마감턱(130)의 외측을 커버하는 형태로 덧씌워지게 발포 성형이 이루어진다.As shown in FIG. 6, the polyurethane foam P1 and the flashing 140 are covered with the polyurethane foam P1 and the flashing 140 in a state where the primary heat insulating layer working process and the flashing process 140 are performed. (P2) is foamed to form a secondary heat insulating layer. At this time, the edge of the polyurethane foam P2 is foam-molded so as to cover the outer side of the finishing step 130.

상기와 같이 2차 단열층이 형성된 폴리우레탄 폼(P2)의 상부에는 첨부된 도 7에서와 같이 내열성과 강도를 갖는 폴리우레아(150)를 분사, 경화하여 루프(120)의 상부 표면을 마감한다.7, the upper surface of the loop 120 is closed by spraying and curing the polyurea 150 having heat resistance and strength, as shown in FIG. 7, to the upper portion of the polyurethane foam P2 on which the secondary insulation layer is formed.

참고로, 상기 폴리우레아(150)는 인장 강도와 경도가 뛰어난 특성으로, 그 용제는 폴리이소시아네트 프리폴리머(Polyisocyana teprepolymer)와 경화제인 폴리아민(Polyamine)을 1:1로 혼합한 것으로 고압 분사장치를 통해 15℃ 이상에서 1800psi ~ 3500psi의 토출 조건으로 직접 성형된 폴리우레탄 폼(P2) 상부에 두께 층을 갖도록 고르게 분사시킨 다음, 상온에서 경화시키는 작업으로 축열조(100)의 루프(120)를 완성한다.For reference, the polyurea 150 is excellent in tensile strength and hardness, and its solvent is a mixture of polyisocyanate prepolymer and polyamine, which is a curing agent, in a ratio of 1: 1. The polyolefin foam P2 is directly sprayed at a temperature of 15 DEG C or higher and a discharge condition of 1800 psi to 3500 psi to form a thick layer on the polyurethane foam P2 and is then uniformly cured at room temperature to complete the loop 120 of the heat storage tank 100. [

상기와 같이 시공된 축열조(100)의 루프(120)는 축열조 내부에서 발생하는 일산화탄소와 같은 부식성 가스로 인해 측벽(110) 상면측과 용접된 루프(120)의 천장용 패널(122)을 이어붙인 경계지점에서 산화가 진행하더라도, 1차 단열층인 폴리우레탄 폼(P1)과 마감턱(130)에 의해 가스와 함께 수증기를 차단하여 산화와 수증기 누출을 방지할 수 있게 한다.The roof 120 of the thermal storage tank 100 constructed as described above is connected to the ceiling panel 122 of the welded loop 120 by the upper surface of the side wall 110 due to corrosive gas such as carbon monoxide generated in the heat storage tank Even if the oxidation progresses at the boundary point, the polyurethane foam P1 and the finishing jaw 130, which are the primary insulating layers, block the water vapor together with the gas, thereby preventing oxidation and vapor leakage.

또한 상기 마감턱(130)의 외측 가장자리와 폴리우레탄 폼(P1)의 외곽에 덧대어진 알루미늄 소재인 플래싱(140)은 더욱이 수증기 및 가스 누출을 차단하고, 이는 2차 단열층을 갖는 폴리우레탄 폼(P2) 및 그 외표면에 분사, 경화 처리된 폴리우레아(150)에 의해 산화의 진행을 최대한 방지시켜 축열조(100)의 측벽(110)과 루프(120) 외벽으로 부식에 의해 배출되는 가스, 수증기로 인한 외부 부식과 오염을 방지할 수 있게 된다.
Further, the flashing 140, which is an aluminum material padded on the outer edge of the finishing jaw 130 and on the outer periphery of the polyurethane foam P1, further blocks water vapor and gas leakage, which is a polyurethane foam having a secondary heat insulating layer P2 And the polyurea 150 sprayed and hardened on the outer surface of the roof 120 to prevent the oxidation from proceeding as much as possible so that the gas discharged from the side wall 110 of the thermal storage tank 100 and the outer wall of the roof 120 by corrosion, It is possible to prevent external corrosion and contamination.
