Description

本発明は、内部蒸発器を有する流体タンクに関し、より詳細には、タンク本体の内部に貯蔵された液相流体をタンク本体の内部に備えられる蒸発器などの変換手段により気相流体に変換し、変換した気相流体を送り出し手段により使用先に送り出すことができ、空間活用性に優れるだけでなく、超低温脆性の引き起こしを防止することができる内部蒸発器を有する流体タンクに関する。 The present invention relates to a fluid tank having an internal evaporator, and more specifically, the liquid phase fluid stored inside the tank body is converted into a gas phase fluid by a conversion means such as an evaporator provided inside the tank body. The present invention relates to a fluid tank having an internal evaporator, which can send the converted vapor phase fluid to a destination by a sending means, which is not only excellent in space utilization but also can prevent the occurrence of ultra-low temperature brittleness.

図１は従来の流体タンク１０を示す図である。 FIG. 1 is a diagram showing a conventional fluid tank 10.

図１を参照すると、従来の流体タンク１０は、液化天然ガスなどの液相流体が貯蔵されるタンク本体１１を含む。 Referring to FIG. 1, the conventional fluid tank 10 includes a tank body 11 in which a liquid phase fluid such as liquefied natural gas is stored.

この際、天然ガスなどの気相流体を使用先に供給するためには、タンク本体１１の内部に貯蔵された液相流体を送り出すことができる送り出し手段１３を備え、これにより、液相流体を外部に送り出す。外部に送り出された液相流体をタンク本体１１の外部に備えられる蒸発器１２により加熱して気相流体に変換させることで、気相流体を使用先に供給することができる。 At this time, in order to supply a gas phase fluid such as natural gas to the destination, a delivery means 13 capable of delivering the liquid phase fluid stored inside the tank body 11 is provided, whereby the liquid phase fluid is supplied. Send to the outside. By heating the liquid phase fluid sent out to the outside by the evaporator 12 provided outside the tank body 11 and converting it into the gas phase fluid, the vapor phase fluid can be supplied to the destination.

この際、使用先に気相流体を供給しないように動作を止めるためには、蒸発器１２前後のバルブ１５、１６を閉める。この際、残存する液相流体は、蒸発器減圧弁１８−１または蒸発器安全弁１８−２を含む蒸発器制御弁１８の制御により、排出部に排出しなければならない。 At this time, in order to stop the operation so as not to supply the vapor phase fluid to the usage destination, the valves 15 and 16 before and after the evaporator 12 are closed. At this time, the remaining liquid phase fluid must be discharged to the discharge section under the control of the evaporator control valve 18 including the evaporator pressure reducing valve 18-1 or the evaporator safety valve 18-2.

なお、液相流体がタンク本体１１の外部に流動し、蒸発器１２により気相流体に変換されるため、これは、超低温の液相流体の超低温脆性を引き起こす恐れがあるだけでなく、気相流体に変換するために蒸発器１２を備えることに伴って別の空間を要するという問題が発生する。 Since the liquid phase fluid flows to the outside of the tank body 11 and is converted into the gas phase fluid by the evaporator 12, this not only may cause the ultra-low temperature brittleness of the ultra-low temperature liquid phase fluid, but also the gas phase. There arises a problem that another space is required due to the provision of the evaporator 12 for converting into a fluid.

図２に図示されている流体タンク２０は、図１に図示されている流体タンク１０の問題点を解消するために導き出されたものであって、蒸発器２２をタンク本体２１の内部に備え、蒸発器２２により変換した気相流体は、圧縮器２２−１などにより気相流体の使用先に送り出す構成である。 The fluid tank 20 shown in FIG. 2 was derived in order to solve the problem of the fluid tank 10 shown in FIG. 1, and has an evaporator 22 inside the tank body 21. The vapor phase fluid converted by the evaporator 22 is sent out to the destination of use of the vapor phase fluid by a compressor 22-1 or the like.

しかし、図２に図示されている流体タンク２０の場合、蒸発器２２によりタンク本体２１の内部の液相流体の全体を加熱しなければならないため、気相流体に変換するためのエネルギーが多量消費されるという問題がある。また、運転の中断時に圧縮器２２−１前後のバルブ２５、２６を閉めることになり、残存する液相流体は、蒸発器減圧弁２８−１または蒸発器安全弁２８−２を含む蒸発器制御弁２８の制御により排出部に排出しなければならない。 However, in the case of the fluid tank 20 shown in FIG. 2, since the entire liquid phase fluid inside the tank body 21 must be heated by the evaporator 22, a large amount of energy for converting to the vapor phase fluid is consumed. There is a problem of being done. Further, when the operation is interrupted, the valves 25 and 26 before and after the compressor 22-1 are closed, and the remaining liquid phase fluid is an evaporator control valve including an evaporator pressure reducing valve 28-1 or an evaporator safety valve 28-2. It must be discharged to the discharge section under the control of 28.

なお、タンク本体２１の内部で変換された気相流体を使用先に送り出すための圧縮器２２−１を別に備えなければならないため、圧縮器２２−１を備えるための別の空間を要するだけでなく、圧縮器２２−１の頻繁な故障によってメンテナンス費用が増大するという問題がある。 Since the compressor 22-1 for sending the gas-phase fluid converted inside the tank body 21 to the destination must be separately provided, only another space for providing the compressor 22-1 is required. However, there is a problem that the maintenance cost increases due to the frequent failure of the compressor 22-1.

図１、図２に図示されている１７−１、１７−２、２７−１、２７−２は、タンク本体１１、２１の圧力制御のためのタンク減圧弁１７−１、２７−１およびタンク安全弁１７−２、２７−２を含むタンク制御弁１７、２７である。 17-1, 17-2, 27-1, 27-2 shown in FIGS. 1 and 2 are the tank pressure reducing valves 17-1, 27-1 and the tank for pressure control of the tank bodies 11 and 21. The tank control valves 17 and 27 including the safety valves 17-2 and 27-2.

本発明は、上述のような問題点を解決するために導き出されたものであって、本発明は、タンク本体の内部に貯蔵された液化天然ガスなどの液相流体をタンク本体の内部に備えられる蒸発器などの変換手段により天然ガスなどの気相流体に変換し、変換した気相流体を送り出し手段により使用先に送り出すことで、液化天然ガスの超低温脆性の引き起こしを防止することができる内部蒸発器を有する流体タンクを提供することを目的とする。 The present invention has been derived in order to solve the above-mentioned problems, and the present invention provides a liquid phase fluid such as liquefied natural gas stored inside the tank body inside the tank body. It is possible to prevent the liquefied natural gas from causing ultra-low temperature brittleness by converting it into a gas phase fluid such as natural gas by a conversion means such as an evaporator and sending the converted gas phase fluid to the destination by a delivery means. It is an object of the present invention to provide a fluid tank having an evaporator.

また、本発明は、液相流体を排出または制御するための制御手段が必要でないことから、空間活用性に優れるだけでなく、製造費用および製造時間を減少させることができる内部蒸発器を有する流体タンクを提供することを目的とする。 Further, the present invention does not require a control means for discharging or controlling the liquid phase fluid, so that the fluid has an internal evaporator which is not only excellent in space utilization but also can reduce the manufacturing cost and the manufacturing time. The purpose is to provide a tank.

FIG. 7 is a diagram showing a fluid tank having an internal evaporator according to a third embodiment of the present invention, and FIG. 8 is another diagram showing a fluid tank having an internal evaporator according to a third embodiment of the present invention.

図７と図８を参照すると、本発明の第３実施形態による内部蒸発器を有する流体タンク１０００の変換手段２００は、高温加熱媒体配管２２０に外部の気体を流入させることができる排出気体配管２６０をさらに含む。 Referring to FIGS. 7 and 8, the conversion means 200 of the fluid tank 1000 having the internal evaporator according to the third embodiment of the present invention is a discharge gas pipe 260 capable of inflowing an external gas into the high temperature heating medium pipe 220. Including further.

すなわち、使用先に気相流体を送り出せずに流体タンクの動作を止める場合、変換手段２００には加熱媒体が残存するため、タンク本体１００の内部に貯蔵された液相流体への影響を最小化するためには加熱媒体を除去しなければならない。 That is, when the operation of the fluid tank is stopped without sending the gas phase fluid to the destination, the heating medium remains in the conversion means 200, so that the influence on the liquid phase fluid stored inside the tank body 100 is minimized. The heating medium must be removed in order to do so.

このために、本発明の第３実施形態による内部蒸発器を有する流体タンク１０００の変換手段２００は、外部の気体を高温加熱媒体配管２２０に供給することができる排出気体配管２６０を含むことで、外部から供給される気体により加熱媒体を低温加熱媒体配管２３０により外部に排出させることで、加熱媒体による液相流体への影響を最小化することができる。 For this purpose, the conversion means 200 of the fluid tank 1000 having the internal evaporator according to the third embodiment of the present invention includes the exhaust gas pipe 260 capable of supplying the external gas to the high temperature heating medium pipe 220. By discharging the heating medium to the outside through the low temperature heating medium pipe 230 by the gas supplied from the outside, the influence of the heating medium on the liquid phase fluid can be minimized.

なお、排出気体配管２６０は、高温加熱媒体配管２２０に流入する外部の気体を制御することができる排出気体制御弁２６１をさらに含む。 The exhaust gas pipe 260 further includes an exhaust gas control valve 261 capable of controlling the external gas flowing into the high temperature heating medium pipe 220.

すなわち、本発明の第３実施形態による内部蒸発器を有する流体タンク１０００は、動作時には排出気体制御弁２６１を閉めて外部の気体が高温加熱媒体配管２２０に流入することを防止し、流体タンク１０００の動作が止めると、外部の気体を高温加熱媒体配管２２０に流動させて低温加熱媒体配管２３０により加熱媒体とともに排出されるようにすることで、変換手段本体２１０の内部に残存する加熱媒体を迅速に除去し、液相流体への影響を最小化することができる。 That is, the fluid tank 1000 having the internal evaporator according to the third embodiment of the present invention closes the exhaust gas control valve 261 during operation to prevent external gas from flowing into the high temperature heating medium pipe 220, and the fluid tank 1000. When the operation of the above is stopped, the external gas is allowed to flow in the high temperature heating medium pipe 220 so that it is discharged together with the heating medium by the low temperature heating medium pipe 230, so that the heating medium remaining inside the conversion means main body 210 can be quickly removed. Can be removed to minimize the effect on the liquid phase fluid.
