Abstract

PURPOSE: A tub for accumulating thermal medium oil is provided to prevent an overheat of a circulation pump and to increase the endurance by introducing thermal medium oil into the circulation pump through a spiral pipe. CONSTITUTION: Thermal medium oil stored in a heat accumulating tub(1) is heated by using an electric heater(70), so thermal medium oil stored in the heat accumulating tub(1) is expanded. When a predetermined pressure is formed in the heat accumulating tub(1), thermal medium oil is introduced into a complement tank(10) through a conveying pipe(11). When a heat exchange of thermal medium oil is carried out, pressure of the heat accumulating tub(1) is lowered so that thermal medium oil introduced into the complement tank(10) is circulated into the heat accumulating tub(1) through the conveying pipe(11). Since the complement tank(10) is positioned between the heat accumulating tub(1) and a water reservoir(2), thermal medium oil stored in the heat accumulating tub(1) is insulated.

Description

열매체유 축열조 { The gathering heat tank of heat medium oil }Thermal oil storage tank {The gathering heat tank of heat medium oil}

본 발명은 열매체유 축열조에 관한 것이며 전기히터를 이용하여 비열이 낮은 열매체유를 가열시켜 축열조에 축열할때 열매체유가 팽창되면 보충탱크로 이송하고, 냉각되면 보충탱크의 열매체유가 다시 축열조로 유입되게 하고 축열조의 열매체유를 수조로 순환시켜 열교환을 할때 고온의 열매체유가 1차 수조를 거쳐 순환펌프로 유입되고 다시 수조를 거쳐 열매체유조로 유입되도록 하여 열매체유의 순환시에 순환펌프의 과열을 예방할 수 있도록 한 것이다.The present invention relates to a heat storage oil heat storage tank and heats the heat medium oil having a low specific heat by using an electric heater to transfer the heat transfer oil to the replenishment tank when the heat storage fluid is expanded, and when cooled, the heat transfer oil of the replenishment tank is introduced again into the heat storage tank. When heat-exchanging the heat storage oil of the heat storage tank through a water tank, the high temperature heat medium oil flows into the circulation pump through the first water tank and then into the heat medium oil tank through the water tank to prevent overheating of the circulation pump during the circulation of the heat medium oil. It is.

심야 전기를 이용하여 축열소재(열매체유와 석재 또는 금속)등을 축열시켰다가 이를 물과 열교환하여 사용되는 축열보일러는 유휴전력의 효율적 사용과 고유가에 대한 대안으로 점차 이용이 증가되고 있다.Heat storage boilers, which are used for heat storage of heat storage materials (heat medium oil, stone or metal) and heat-exchanging with water, are increasingly being used as an alternative to efficient use of idle power and high oil prices.

이와 같은 축열보일러에서 고체의 경우 산화와 부식이 빠르게 진행되어 사용수명이 짧고 축열과정에서 열의 손실이 많아 효율이 떨어지는 결점이 있고 물의 경우에는 비열(단위중량의 물체온도를 1℃ 높이는데 소요되는 열량)이 높아 축열효율이 떨어지고 열팽창계수가 높아 탱크의 용량이 대형화 되는 폐단이 있으며 또 열매체유의 경우에는 축열온도가 320℃에 이르고 비열이 낮아 축열효율이 높아 널리 이용되고 있으나 이 또한 축열되면서 320℃에 이르면 체적이 20% 팽창이 이루어져 팽창상태를 고려하여 축열조에 열매체유의 장입량을 조절해야 하는 결점과 고온으로 축열되고 열매체유를 순환시켜 열교환할때 열매체유의 고온이 순환펌프에 그대로 전달되므로서 순환펌프는 고온(320℃)에 노출되므로 작동에 변형이 없는 소재로 구성되어야 내구성이 유지되므로 이에 사용되는 순환펌프는 고가이고 내구연한이 짧아 잦은 교체가 요구되므로 경제성이 떨어지는 폐단이 있어 왔다.In such heat storage boilers, solids undergo rapid oxidation and corrosion, resulting in short service life and high loss of heat in the heat storage process, resulting in inefficient efficiency. In the case of water, the specific heat (heat amount required to increase the object temperature of unit weight by 1 ℃). High heat storage efficiency, low thermal expansion coefficient, large capacity of tank, and large capacity of tank. Also, in case of thermal oil, heat storage temperature reaches 320 ℃ and specific heat is low, so heat storage efficiency is widely used. As early as 20% of the volume is expanded, the heat storage oil is transferred to the circulation pump because the high temperature of the heat medium oil is transferred to the circulation pump as it is accumulated at the high temperature and heat-reduced and heat exchanged through the heat oil in consideration of the expansion state. Because it is exposed to high temperature (320 ℃), it should be made of material without deformation in durability Since it is maintained, the circulation pump used for this is expensive and its durability is short, so that frequent replacement has been required, resulting in inferior economic feasibility.

이에 본 발명은 열매체유를 이용하는 축열조에서 고온으로 축열되어 팽창된 열매체유는 수조와 축열조 사이의 보충탱크로 이송되고 열매체유가 냉각되면서 수축되면 열매체유조로 유입되게 하고, 축열조의 열매체유를 순환시켜 열교환할때 수조상부의 나선형 파이프를 거쳐 순환펌프로 유입되고 수조하방의 나선형 파이프를 거쳐 축열조로 유입되도록 하여 순환펌프의 과열을 예방하고 내구성을 증대시킬 수 있도록 한 축열조를 제공함에 목적이 있다.Accordingly, the present invention is thermally expanded by heat storage in the heat storage tank using the heat medium oil is expanded to the replenishment tank between the water tank and the heat storage tank, and when the heat medium oil is cooled and contracted to enter the heat medium oil tank, the heat medium of the heat storage tank circulating heat exchange The purpose of the present invention is to provide a heat storage tank to prevent the overheating of the circulation pump and increase durability by introducing the circulation pump through the spiral pipe at the top of the tank and entering the heat storage tank via the spiral pipe below the tank.

축열조(1) 외곽에는 수조(2)를 형성하고 축열조(1)의 열매체유를 순환펌프(4)로 수조(2)의 나선형으로 설치되는 열교환파이프(3)로 순환되도록한 통상의 축열조에 있어서 축열조(1)와 수조(2) 사이에 보충탱크(10)를 형성하여 열매체유의 팽창시에는 보충탱크(10)로 유입되고 수축시에는 보충탱크(10)의 열매체유가 축열조(1)로 다시 유입되도록 이송관(11)을 형성하며 축열조(1)의 열매체유는 나선형으로 순환되는 열교환파이프(3)를 상하 2단으로 하여 상부파이프(20)의 하부출구를 순환펌프(4)의 유입구에, 순환펌프(4)의 출구는 하부파이프(30)의 하부유입구에, 하부파이프(30)의 출구는 축열조에(1)에 연결하여 순환하게 한 구성이다.In a conventional heat storage tank in which a water tank 2 is formed outside the heat storage tank 1 and the heat medium oil of the heat storage tank 1 is circulated to a heat exchange pipe 3 installed in a spiral of the water tank 2 by a circulation pump 4. A replenishment tank 10 is formed between the heat storage tank 1 and the water tank 2 so that the thermal oil flows into the replenishment tank 10 when the thermal fluid expands, and when shrinked, the heat medium oil of the replenishment tank 10 flows back into the heat storage tank 1. The heat transfer oil of the heat storage tank 1 is formed into a heat exchange pipe 3 helically circulated in two stages up and down so that the lower outlet of the upper pipe 20 is connected to the inlet of the circulation pump 4. The outlet of the circulation pump 4 is connected to the lower inlet of the lower pipe 30 and the outlet of the lower pipe 30 is connected to the heat storage tank 1 to circulate.

이와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

전기히터(70)를 가열시켜 축열조(1)의 열매체유를 가열시키게 되면 축열조(1)의 열매체유가 축열되면서 팽창하게 되고 축열조(1)에 일정 압력이 형성되면 열매체유는 이송관(11)을 통하여 보충탱크(10)로 유입이 이루어지고, 열매체유의 열교환으로 냉각이 되면 축열조(1)의 압력이 떨어져 보충탱크(10)로 유입된 열매체유는 이송관(11)을 통하여 축열조(1)로 다시 유입되는 과정으로 반복하게 된다.When the electric heater 70 is heated to heat the heat medium oil of the heat storage tank 1, the heat medium oil of the heat storage tank 1 expands as it heats up, and when a predetermined pressure is formed in the heat storage tank 1, the heat medium oil opens the transfer pipe 11. Inflow to the replenishment tank (10) is made through, and when the heat exchange of the heat medium oil is cooled, the pressure of the heat storage tank (1) is dropped, the heat medium oil introduced into the replenishment tank (10) to the heat storage tank (1) through the transfer pipe (11) The process is repeated as it is introduced again.

이 때 축열조(1)의 팽창된 열매체유를 유입하는 보충탱크(10)는 축열조(1)와 수조(2) 사이에 위치되므로 축열조(1)의 축열된 열매체유는 단열이 유지되어 열의 손실이 해소되고 안전하게 된다.At this time, the replenishment tank 10 for introducing the expanded heat medium oil of the heat storage tank 1 is located between the heat storage tank 1 and the water tank 2, so that the heat storage oil of the heat storage tank 1 is thermally insulated and heat loss is maintained. Resolved and secured.

또 축열조(1)에 축열된 열매체유는 순환펌프(4)의 동작으로 나선형 열교환 파이프(3)를 순환하면서 열교환이 이루어지게 된다.In addition, the heat medium oil accumulated in the heat storage tank 1 circulates through the helical heat exchange pipe 3 by the operation of the circulation pump 4, thereby performing heat exchange.

즉, 순환펌프(4)가 동작되면 축열조(1)의 열매체유는 열교환파이프(3)를 구성하는 상부파이프(20)를 통하여 수조(2)의 물에서 열교환이 이루어지면서 순환펌프(4)의 유입구로 유입이 이루어지고 순환펌프(4)의 유입구에 도달한 열매체유는 냉각되어 온도가 떨어진 상태가 되고 동열매체유는 순환펌프(4)의 출구를 통하여 하부파이프(30)로 압송되어 수조(2)의 물에서 2차 열교환이 이루어지면서 축열조(1)로 유입이 이루어지게 되며 축열조(1)의 열매체유는 수조(2)의 상부파이프(20)에서 1차 열교환이 이루어져 1차 냉각된 열매체유가 순환펌프(4)에 전달되므로 순환펌프(4)의 과열을 예방할 수 있게 되고 또 순환펌프(4)를 거친 열매체유는 수조(2)의 하부파이프(30)에서 2차 열교환되면서 축열조(1)로 유입되므로 열교환의 효율이 증대되는 것이다.That is, when the circulating pump 4 is operated, the heat medium oil of the heat storage tank 1 undergoes heat exchange in the water of the water tank 2 through the upper pipe 20 constituting the heat exchange pipe 3, Inflow is made to the inlet and the heat medium oil which reaches the inlet of the circulation pump 4 is cooled and the temperature is dropped, and the copper heat medium oil is pumped to the lower pipe 30 through the outlet of the circulation pump 4 to receive a water tank ( The secondary heat exchange in the water of 2) is introduced into the heat storage tank (1) and the heat medium oil of the heat storage tank (1) is the first heat exchange in the upper pipe (20) of the water tank (2) to the first cooling medium Since the oil is delivered to the circulation pump 4, it is possible to prevent overheating of the circulation pump 4, and the heat medium oil having passed through the circulation pump 4 is heat-exchanged in the lower pipe 30 of the water tank 2 as the heat storage tank 1. ), So the efficiency of heat exchange is increased.

또 본 고안은 열교환파이프(3)를 한쌍으로 하여 도3과 같이 중첩되도록 결합하고 상부파이프(20)는 순환펌프(4)의 유입구에 순환펌프(4)의 출구는 하부파이프(30)의 하방유입구에, 하부파이프(30)의 출구는 축열조(1)에 유입되도록 연결하여 순환되도록 구성하여 사용할수도 있다.In addition, the present invention combines the heat exchange pipe (3) as a pair to overlap as shown in Figure 3 and the upper pipe 20 is the inlet of the circulation pump 4, the outlet of the circulation pump 4 is lower than the lower pipe 30 At the inlet, the outlet of the lower pipe 30 may be configured to be circulated by being connected to the heat storage tank (1).

이와같이 열매체유를 이용하는 축열조는 축열조(1)와 수조(2) 사이에 열매체유의 팽창시 유입되는 보충탱크(10)를 구비하고 수조(2)에 설치되는 열교환파이프(3)는 상하 2단으로 하여 상부파이프(20)를 통과한 열매체유가 순환펌프(4)에 전달되고 순환펌프(4)를 거친 열매체유는 하부파이프(30)를 통과하면서 2차 열교환이 이루어지면서 축열조(1)로 유입되므로 축열조의 열효율이 증대되고 순환펌프의 과열을 예방하게 되므로서 순환펌프의 내구성을 증대시킬 수 있게 되는 것이다.Thus, the heat storage tank using the heat medium oil is provided between the heat storage tank (1) and the water tank (2) with a supplemental tank (10) flowing in when the heat medium oil is expanded, and the heat exchange pipe (3) installed in the water tank (2) has two stages up and down The heat medium oil passing through the upper pipe 20 is transferred to the circulation pump 4, and the heat medium oil passing through the circulation pump 4 flows into the heat storage tank 1 while undergoing secondary heat exchange while passing through the lower pipe 30. Since the thermal efficiency of the circulation pump is prevented from being overheated, the durability of the circulation pump can be increased.

따라서 이상과 같은 본 발명은 축열조의 열매체유가 축열로 팽창되면 축열조와 수조사이의 보충탱크에 유입되고, 냉각시에는 축열조로 다시 유입되며, 축열조의 열매체유를 이용하며 열교환시에는 열교환파이프의 상부파이프에서 1차 열교환을 거친 다음 순환펌프로 유입되고 하부파이프에서 2차열교환이 이루어지게 하므로서 순환펌프의 과열을 예방하고 내구성을 증대시켜 장구히 사용할 수 있게 되고 축열조에 축열된 열매체유는 열교환효율을 증대시킬 수 있는 유용한 발명이다.Therefore, in the present invention as described above, when the heat medium of the heat storage tank is expanded to the heat storage, it is introduced into the replenishment tank of the heat storage tank and the irradiated water, and when it is cooled, it flows back into the heat storage tank. After undergoing the first heat exchange in the circulating pump and the second heat exchange in the lower pipe, it prevents overheating of the circulating pump and increases its durability so that it can be used for a long time. It is a useful invention that can be made.
