Description

내부 증발기를 가진 유체탱크{Fluid Tank Having Internal Vaporizers}Fluid Tank Having Internal Vaporizers

본 발명은 내부 증발기를 가진 유체탱크에 관한 것으로서, 더욱 상세하게는 탱크본체 내부에 저장된 액상유체를 탱크본체 내부에 구비되는 증발기 등의 변환수단을 통해 기상유체로 변환하고, 변환된 기상유체를 송출수단을 통해 사용처로 송출할 수 있어 공간 활용성이 뛰어날 뿐만 아니라, 초저온취성의 유발을 방지할 수 있는 내부 증발기를 가진 유체탱크에 관한 것이다.The present invention relates to a fluid tank having an internal evaporator, and more specifically, to convert the liquid fluid stored in the tank body into a gaseous fluid through a conversion means such as an evaporator provided in the tank body, and transmit the converted gaseous fluid It relates to a fluid tank having an internal evaporator that can be sent to a place of use through a means, and thus has excellent space utilization and can prevent the occurrence of ultra-low temperature embrittlement.

도 1은 종래의 유체탱크(10)를 나타낸 도면이다.1 is a view showing a conventional fluid tank 10.

도 1을 참조하면, 종래의 유체탱크(10)는 액화천연가스 등의 액상유체가 저장되는 탱크본체(11)를 포함한다.Referring to FIG. 1, the conventional fluid tank 10 includes a tank body 11 in which liquid fluid such as liquefied natural gas is stored.

이때, 사용처로 천연가스 등의 기상유체를 사용처로 공급하기 위해서는 탱크본체(11) 내부에 저장된 액상유체를 송출할 수 있는 송출수단(13)을 통해 외부로 송출하고, 외부로 송출된 액상유체는 탱크본체(11) 외부에 구비되는 증발기(12)를 통해 가열하여 기상유체로 변환시킴으로써, 기상유체를 사용처로 공급할 수 있다.At this time, in order to supply a gaseous fluid such as natural gas to the user to the user, the liquid fluid stored in the tank body 11 is sent out through the sending means 13 capable of sending out, and the liquid fluid sent out is By heating through the evaporator 12 provided outside the tank body 11 to convert it into a gaseous fluid, the gaseous fluid can be supplied to a user.

그러나 사용처로 기상유체를 공급하지 않도록 동작을 멈추기 위해서는 증발기(12)의 전후의 밸브(15, 16)를 잠그게 되는데, 이때 잔존하는 액상유체는 증발기 감압밸브(18-1) 또는 증발기 안전밸브(18-2)를 포함하는 증발기제어밸브(18)의 제어를 통해 배출부로 배출시켜야 한다.However, in order to stop the operation so as not to supply the gaseous fluid to the place of use, the valves 15 and 16 before and after the evaporator 12 are closed. At this time, the remaining liquid fluid is the evaporator decompression valve 18-1 or the evaporator safety valve ( 18-2) should be discharged to the discharge through the control of the evaporator control valve 18, including.

아울러, 액상유체가 탱크본체(11) 외부로 유동하여 증발기(12)를 통해 기상유체로 변환되므로, 초저온의 액상유체의 초저온취성을 유발할 위험이 존재할 뿐만 아니라, 기상유체로 변환시키기 위한 증발기(12)의 구비에 따른 별도의 공간을 필요로 하는 문제점이 있다.In addition, since the liquid fluid flows out of the tank body 11 and is converted into a gaseous fluid through the evaporator 12, there is a risk of causing ultra-low temperature embrittlement of the cryogenic liquid fluid, as well as an evaporator 12 for converting it into a gaseous fluid. ), there is a problem that requires a separate space.

도 2에 도시된 유체탱크(20)는 도 1에 도시된 유체탱크(10)의 문제점을 해소하기 위하여 안출된 것으로, 증발기(22)를 탱크본체(21) 내부에 구비하고, 증발기(22)를 통해 변환된 기상유체는 압축기(22-1) 등을 통해 기상유체 사용처로 송출하는 유체탱크(20)이다.The fluid tank 20 shown in FIG. 2 was devised to solve the problem of the fluid tank 10 shown in FIG. 1, and provided with an evaporator 22 inside the tank body 21, the evaporator 22 The gaseous fluid converted through is a fluid tank 20 that is sent to a gaseous fluid use place through a compressor 22-1 or the like.

그러나 도 2에 도시된 유체탱크(20)의 경우, 증발기(22)를 통해 탱크본체(21) 내부의 액상유체 전체를 가열해야 하므로, 기상유체로 변환시키기 위한 에너지가 많이 소모되는 문제점이 있으며, 운전 중단 시 압축기(22-1) 전후의 밸브(25, 26)를 잠그게 되고, 잔존하는 액상유체는 증발기 감압밸브(28-1) 또는 증발기 안전밸브(28-2)를 포함하는 증발기제어밸브(28)의 제어를 통해 배출부로 배출시켜야 한다.However, in the case of the fluid tank 20 shown in FIG. 2, since the entire liquid fluid inside the tank body 21 must be heated through the evaporator 22, energy for converting it into a gaseous fluid is consumed. When the operation is stopped, the valves 25 and 26 before and after the compressor 22-1 are closed, and the remaining liquid fluid is an evaporator control valve including an evaporator decompression valve 28-1 or an evaporator safety valve 28-2. It should be discharged to the discharge section through the control of (28).

아울러, 탱크본체(21) 내부에서 변환된 기상유체를 사용처로 송출하기 위한 압축기(22-1)를 별도로 구비해야 하므로, 압축기(22-1)를 구비하기 위한 별도의 공간을 필요로 하며, 압축기(22-1)의 잦은 고장으로 인해 유지보수 비용이 증대되는 문제점이 있다.In addition, since the compressor 22-1 for transmitting the gaseous fluid converted from the inside of the tank body 21 to the user must be provided separately, a separate space for providing the compressor 22-1 is required, and the compressor Due to the frequent failure of (22-1), there is a problem that the maintenance cost is increased.

도 1, 도 2에 도시된 17-1, 17-2, 27-1, 27-2는 탱크본체(11, 21)의 압력 제어를 위한 탱크감압밸브(17-1, 27-1) 및 탱크안전밸브(17-2, 27-2)를 포함하는 탱크제어밸브(17, 27)이다.17-1, 17-2, 27-1, and 27-2 shown in FIGS. 1 and 2 are tank pressure reducing valves 17-1, 27-1 and tanks for controlling the pressure of the tank bodies 11, 21 It is a tank control valve (17, 27) including the safety valve (17-2, 27-2).
