Description

本発明は、請求項１のおいて書きに記載の、ガスエンジンのための燃料供給・洗浄装置に関する。さらに本発明は、当該燃料供給・洗浄装置のバルブユニットと、当該燃料供給・洗浄装置を有するガスエンジンと、に関する。   The present invention relates to a fuel supply / cleaning device for a gas engine as described in claim 1. The present invention further relates to a valve unit of the fuel supply / cleaning apparatus and a gas engine having the fuel supply / cleaning apparatus.

燃料として気体の媒体が準備される内燃機関は、実践から充分に知られており、ガスエンジンとも呼ばれる。そのようなガスエンジンのシリンダ内で、ガス管を介してガスエンジンのシリンダに供給され得る気体燃料が燃焼される。ガスエンジン内で気体燃料が燃焼されないのであれば、ガスエンジンに至るガス管を洗浄しなくてはならず、実践に従えば、洗浄剤として典型的に気体の窒素が使用される。気体洗浄剤は、洗浄剤導管を介してガス管に導入され、ガス管と洗浄剤導管とはバルブユニットを介して連結されていて、ガスエンジンのシリンダ内で気体燃料が燃焼される第１駆動状態においては、バルブユニットは、ガス管と洗浄剤導管とを互いに分離するが、他方、ガスエンジンのシリンダ内で気体燃料が燃焼されない第２駆動状態においては、バルブユニットは、洗浄剤導管をガス管に連結させるようになっている。第１駆動状態においてガス管と洗浄剤導管とを互いに分離し、第２駆動状態においてガス管と洗浄剤導管とを互いに連結させる燃料供給・洗浄装置のバルブユニットには、典型的には漏れがあり、実践から知られているガスエンジンには、この漏れは確定的には排出され得ないという問題がある。それゆえ、そのバルブユニットの領域において生じる漏れを確実に操作できる、ガスエンジンのための燃料供給・洗浄装置が必要である。   Internal combustion engines in which a gaseous medium is prepared as fuel are well known from practice and are also called gas engines. In such a gas engine cylinder, gaseous fuel that can be supplied to the cylinder of the gas engine via a gas pipe is combusted. If the gaseous fuel is not burned in the gas engine, the gas tube leading to the gas engine must be cleaned, and according to practice, gaseous nitrogen is typically used as a cleaning agent. The gas cleaning agent is introduced into the gas pipe through the cleaning agent conduit, and the gas pipe and the cleaning agent conduit are connected to each other through the valve unit so that the gaseous fuel is combusted in the cylinder of the gas engine. In the state, the valve unit separates the gas pipe and the cleaning agent conduit from each other, whereas in the second drive state, where the gaseous fuel is not burned in the cylinder of the gas engine, the valve unit gasses the cleaning agent conduit. It is designed to be connected to a tube. The valve unit of the fuel supply / cleaning apparatus that separates the gas pipe and the cleaning agent conduit from each other in the first driving state and connects the gas pipe and the cleaning agent conduit to each other in the second driving state typically has leakage. There is a problem with gas engines known from practice that this leak cannot be exhausted deterministically. Therefore, there is a need for a fuel supply and cleaning device for gas engines that can reliably operate leaks that occur in the area of the valve unit.

ここから本発明は、ガスエンジンのための新式の燃料供給・洗浄装置と、当該燃料供給・洗浄装置のバルブユニットと、当該燃料供給・洗浄装置を有するガスエンジンと、を提供することを課題とする。   Accordingly, it is an object of the present invention to provide a new fuel supply / cleaning device for a gas engine, a valve unit of the fuel supply / cleaning device, and a gas engine having the fuel supply / cleaning device. To do.

この課題は、請求項１に記載の燃料供給・洗浄装置によって解決される。本発明に従えば、ガス管は、主流室と副流室とを有する二重壁のガス管として形成されている。バルブユニットは、第１安全バルブを備え、当該第１安全バルブは、ガス管の主流室と洗浄剤導管との間に配置されていて、当該第１安全バルブは、第１駆動状態において、ガス管の主流室と洗浄剤導管とを互いに分離し、第２駆動状態において、ガス管の主流室と洗浄剤導管とを互いに接続するようになっている。バルブユニットは、さらに第２安全バルブを備え、当該第２安全バルブは、ガス管の副流室と洗浄剤導管との間に配置されていて、当該第２安全バルブは、第１駆動状態において、洗浄剤導管とガス管の副流室とを互いに接続し、第２駆動状態において、洗浄剤導管とガス管の副流室とを互いに分離するようになっている。バルブユニットが２つの安全バルブを備える本発明に係る燃料供給・洗浄装置は、漏れの確実な操作を可能にする。   This problem is solved by the fuel supply / cleaning apparatus according to claim 1. According to the invention, the gas pipe is formed as a double-walled gas pipe having a main flow chamber and a subflow chamber. The valve unit includes a first safety valve, and the first safety valve is disposed between the main flow chamber of the gas pipe and the detergent conduit, and the first safety valve is a gas in the first driving state. The main flow chamber of the pipe and the cleaning agent conduit are separated from each other, and in the second driving state, the main flow chamber of the gas pipe and the cleaning agent conduit are connected to each other. The valve unit further includes a second safety valve, the second safety valve being disposed between the sub-flow chamber of the gas pipe and the cleaning agent conduit, wherein the second safety valve is in the first driving state. The cleaning agent conduit and the gas pipe sub-flow chamber are connected to each other, and in the second driving state, the cleaning agent conduit and the gas pipe sub-flow chamber are separated from each other. The fuel supply / cleaning apparatus according to the present invention in which the valve unit includes two safety valves enables reliable operation of leakage.

好適には第２安全バルブは第１駆動状態において、第１安全バルブの燃料漏れを、洗浄剤導管からガス管の副流室に誘導する。これによって、燃料漏れは、特に有利に排出され得る。   Preferably, the second safety valve directs fuel leakage of the first safety valve from the cleaning agent conduit to the secondary flow chamber of the gas pipe in the first drive state. Thereby, fuel leaks can be discharged particularly advantageously.

当該燃料供給・洗浄装置のための洗浄装置は、請求項８に定義されている。   A cleaning device for the fuel supply and cleaning device is defined in claim 8.

燃料供給・洗浄装置を有するガスエンジンは、請求項１０に定義されている。   A gas engine having a fuel supply and cleaning device is defined in claim 10.

本発明の好ましい様態は、従属請求項と後続の記述とからもたらされる。本発明の実施例は、図に基づいてより詳しく説明されるが、これに限定されるものではない。図に示されるのは以下である。   Preferred embodiments of the invention result from the dependent claims and the subsequent description. Embodiments of the present invention will be described in more detail with reference to the drawings, but are not limited thereto. The following is shown in the figure.

第１駆動状態における、本発明に係る燃料供給・洗浄装置の原理図である。It is a principle figure of the fuel supply and washing device concerning the present invention in the 1st drive state. 第２駆動状態における、本発明に係る燃料供給・洗浄装置である。It is a fuel supply and washing | cleaning apparatus which concerns on this invention in a 2nd drive state. 燃料供給・洗浄装置の好ましい実施例の詳細図である。1 is a detailed view of a preferred embodiment of a fuel supply and cleaning device.

本件の発明は、ガスエンジンのための燃料供給・洗浄装置および当該燃料供給・洗浄装置を有するガスエンジンに関する。図１および図２は、異なる駆動状態における、ガスエンジンのための本発明に係る燃料供給・洗浄装置１０の、非常に概略化された原理図を示している。   The present invention relates to a fuel supply / cleaning device for a gas engine and a gas engine having the fuel supply / cleaning device. 1 and 2 show a very schematic diagram of the principle of a fuel supply and cleaning device 10 according to the invention for a gas engine in different driving conditions.

燃料供給・洗浄装置１０は、第１駆動状態において気体燃料１２（図１参照）をガスエンジンのシリンダに供給できるガス管１１を備える。さらに燃料供給・洗浄装置１０は、気体洗浄剤１４の調達に使われる洗浄剤導管１３を備え、ガス管１１と洗浄剤導管１３とは、バルブユニット１５を介して連結されている。第２駆動状態において（図２参照）、洗浄剤１４は、ガス管１１を介して供給される。   The fuel supply / cleaning apparatus 10 includes a gas pipe 11 that can supply gaseous fuel 12 (see FIG. 1) to a cylinder of a gas engine in the first driving state. Further, the fuel supply / cleaning apparatus 10 includes a cleaning agent conduit 13 used for procurement of the gaseous cleaning agent 14, and the gas pipe 11 and the cleaning agent conduit 13 are connected via a valve unit 15. In the second driving state (see FIG. 2), the cleaning agent 14 is supplied via the gas pipe 11.

ガスエンジンのシリンダ内で気体燃料１２が燃焼される、燃料供給・洗浄装置１０の第１駆動状態において（図１参照）、ガス管１１は、気体燃料１２をガスエンジンの方向に供給するのに使われ、バルブユニット１５は、ガス管１１と洗浄剤導管１３とを互いに分離することになっている。これに対して、ガスエンジンのシリンダ内で気体燃料が燃焼されず、ガスエンジンに至るガス管１１が気体洗浄剤１４を使って洗浄されるべき第２駆動状態において（図２参照）、バルブユニット１５が洗浄剤導管１３をガス管１１に連結させるので、洗浄剤導管１３から用意される気体洗浄剤１４をガスエンジンに至るガス管１１の洗浄に利用できる。   In the first driving state of the fuel supply / cleaning apparatus 10 in which the gaseous fuel 12 is combusted in the cylinder of the gas engine (see FIG. 1), the gas pipe 11 supplies the gaseous fuel 12 in the direction of the gas engine. Used, the valve unit 15 is to separate the gas pipe 11 and the cleaning agent conduit 13 from each other. On the other hand, in the second driving state in which the gas fuel 11 is not burned in the cylinder of the gas engine and the gas pipe 11 reaching the gas engine is to be cleaned using the gas cleaning agent 14 (see FIG. 2), the valve unit. Since 15 connects the cleaning agent conduit 13 to the gas pipe 11, the gas cleaning agent 14 prepared from the cleaning agent conduit 13 can be used for cleaning the gas pipe 11 leading to the gas engine.

ガス管１１は、半径方向内側の主流室１６と半径方向外側の副流室１７とを備える、二重壁のガス管として実施されている。洗浄剤導管１３は一重壁の導管として実施されており、それに従って１つの流室しか備えていない。   The gas pipe 11 is implemented as a double-walled gas pipe comprising a radially inner main flow chamber 16 and a radially outer subflow chamber 17. The cleaning agent conduit 13 is implemented as a single wall conduit and accordingly has only one flow chamber.

燃料供給・洗浄装置１０のバルブユニット１５は、第１安全バルブ１８を備え、当該第１安全バルブ１８は、二重壁のガス管１１の主流室１６と洗浄剤導管１３との間に配置されていて、当該第１安全バルブ１８は、ガスエンジン内で気体燃料が燃焼される第１駆動状態において（図１参照）、ガス管１１の主流室１６を洗浄剤導管１３から分離するようになっているので、それに従って、気体燃料は、二重壁のガス管１１の主流室１６を通ってガスエンジンのシリンダに供給され得る。これに対して、第２駆動状態において（図２参照）、第１安全バルブ１８は、二重壁のガス管１１の主流室１６と洗浄剤導管１３とを互いに接続しているので、この第１安全バルブ１８を介して、洗浄剤導管１３から用意される気体洗浄剤１４を、ガス管１１の主流室１６を洗浄するために、この主流室１６に誘導できる。   The valve unit 15 of the fuel supply / cleaning apparatus 10 includes a first safety valve 18, which is disposed between the main flow chamber 16 of the double-walled gas pipe 11 and the cleaning agent conduit 13. Thus, the first safety valve 18 separates the main flow chamber 16 of the gas pipe 11 from the cleaning agent conduit 13 in the first driving state in which the gaseous fuel is combusted in the gas engine (see FIG. 1). Thus, according to this, gaseous fuel can be supplied to the cylinder of the gas engine through the main flow chamber 16 of the double-walled gas pipe 11. In contrast, in the second driving state (see FIG. 2), the first safety valve 18 connects the main flow chamber 16 of the double-walled gas pipe 11 and the cleaning agent conduit 13 to each other. Via a safety valve 18, the gas cleaning agent 14 provided from the cleaning agent conduit 13 can be guided to this main flow chamber 16 in order to clean the main flow chamber 16 of the gas pipe 11.

第１安全バルブ１８に加えて、燃料供給・洗浄装置１０のバルブユニット１５は、第２安全バルブ１９を備える。この第２安全バルブ１９は、二重壁のガス管１１の副流室１７と洗浄剤導管１３との間に配置されていて、当該第２安全バルブ１９は、ガス管１１の主流室１６を介して気体燃料がガスエンジンのシリンダに供給される第１駆動状態において（図１参照）、洗浄剤導管１３とガス管１１の副流室１７とを互いに接続するようになっているので、第２安全バルブ１９、は第１駆動状態において、ガス管１１の主流室１６から洗浄剤導管１３に達する第１安全バルブ１８の燃料漏れを、漏れ蓄積室２７を介して二重壁のガス管１１の副流室１７に誘導する。図１は、選択的に排水口２１を介して吸出されてよい第１駆動状態における燃料漏れ２０を、破線で明示している。ガスエンジンのシリンダ内で燃料が燃焼されず、二重壁のガス管１１の主流室１６が気体洗浄剤１４で洗浄されるべき第２駆動状態において（図２参照）、第２安全バルブ１９は、洗浄剤導管１３をガス管１１の副流室１７から分離する。   In addition to the first safety valve 18, the valve unit 15 of the fuel supply / cleaning apparatus 10 includes a second safety valve 19. The second safety valve 19 is disposed between the side flow chamber 17 of the double-walled gas pipe 11 and the cleaning agent conduit 13, and the second safety valve 19 passes through the main flow chamber 16 of the gas pipe 11. In the first driving state in which the gaseous fuel is supplied to the cylinder of the gas engine (see FIG. 1), the cleaning agent conduit 13 and the subflow chamber 17 of the gas pipe 11 are connected to each other. In the first driving state, the two safety valve 19 causes the fuel leakage of the first safety valve 18 reaching the cleaning agent conduit 13 from the main flow chamber 16 of the gas pipe 11, and the double-walled gas pipe 11 through the leak accumulation chamber 27. To the secondary flow chamber 17. FIG. 1 clearly shows a fuel leak 20 in a first driving state that may be selectively sucked out through the drain 21 by a broken line. In the second driving state where the fuel is not burned in the cylinder of the gas engine and the main flow chamber 16 of the double-walled gas pipe 11 is to be cleaned with the gas cleaner 14 (see FIG. 2), the second safety valve 19 is The cleaning agent conduit 13 is separated from the side flow chamber 17 of the gas pipe 11.

それに従って、気体燃料１２がガス管１１の主流室１６を介してガスエンジンのシリンダに運ばれるべき第１駆動状態において（図１参照）、ガス管１１の主流室１６内の圧力は、洗浄剤導管１３内の圧力よりも大きく、この圧力差によって、第１安全バルブ１８は、自動的に閉じ、ガス管１１の主流室１６を洗浄剤導管１３から自動的に分離する。第１駆動状態において、洗浄剤導管１３内の圧力は、比較的小さく、それによって、第２安全バルブ１９が自動的に開き、ガス管１１の副流室１７を自動的に洗浄剤導管１３と接続する。これは、図１で示されているので、それに従って、第１駆動状態において、第１安全バルブ１８の燃料漏れ２０は、第２安全バルブ１９を介して確定的に、ガス管１１の副流室１７に誘導され得る。   Accordingly, in the first driving state in which the gaseous fuel 12 is to be carried to the cylinder of the gas engine via the main flow chamber 16 of the gas pipe 11 (see FIG. 1), the pressure in the main flow chamber 16 of the gas pipe 11 Due to this pressure difference being greater than the pressure in the conduit 13, the first safety valve 18 is automatically closed and the main flow chamber 16 of the gas pipe 11 is automatically separated from the cleaning agent conduit 13. In the first drive state, the pressure in the cleaning agent conduit 13 is relatively small, so that the second safety valve 19 is automatically opened and the sub-flow chamber 17 of the gas pipe 11 is automatically connected to the cleaning agent conduit 13. Connecting. This is shown in FIG. 1, and accordingly, in the first drive state, the fuel leak 20 of the first safety valve 18 is deterministically via the second safety valve 19, and the secondary flow of the gas pipe 11. Can be directed to chamber 17.

第２駆動状態において（図２参照）、洗浄剤導管１３内の圧力は、上昇しており、それによって、第１安全バルブ１８は、自動的に開き、ガス管１１の主流室１６を自動的に洗浄剤導管１３と接続する。第２駆動状態における洗浄剤導管１３内のこの圧力上昇によって、第２安全バルブ１９は、自動的に閉じ、第２安全バルブ１９は、ガス管１１の副流室１７を洗浄剤導管１３から自動的に分離する。   In the second drive state (see FIG. 2), the pressure in the cleaning agent conduit 13 is rising, whereby the first safety valve 18 is automatically opened and the main flow chamber 16 of the gas pipe 11 is automatically opened. To the cleaning agent conduit 13. Due to this pressure increase in the cleaning agent conduit 13 in the second drive state, the second safety valve 19 is automatically closed, and the second safety valve 19 automatically opens the secondary flow chamber 17 of the gas pipe 11 from the cleaning agent conduit 13. Separate.

第１駆動状態において、つまりガスエンジンのシリンダ内で気体燃料が燃焼される場合において、バルブユニット１５は、洗浄剤導管１３に対するガス管１１の閉鎖を保証する。この駆動状態において、第１安全バルブ１８を介して流れる漏れは、第２安全バルブ１９を介して確定的に排出され得る。第１安全バルブ１８は、ガス逆止バルブとも呼ばれてよく、第２安全バルブ１９はパイプ破損防止バルブとも呼ばれてよい。第１駆動状態において、第１安全バルブ１８を介して流れ得る燃料の漏れ流２０は、確定的に排出され、それに従って、制御されることなく周囲に漏れ出得ない。燃料漏れ２０が確定的に排出されるので、この燃料漏れ２０は、示されていないセンサを使って検知され得、燃料漏れ２０が増加した際には第１安全バルブ１８の故障を推論できる。   In the first drive state, i.e. when gaseous fuel is combusted in the cylinder of the gas engine, the valve unit 15 ensures the closure of the gas pipe 11 with respect to the detergent conduit 13. In this drive state, leaks flowing through the first safety valve 18 can be definitely discharged through the second safety valve 19. The first safety valve 18 may be called a gas check valve, and the second safety valve 19 may be called a pipe breakage prevention valve. In the first drive state, the fuel leakage flow 20 that can flow through the first safety valve 18 is definitely discharged and accordingly cannot leak out to the surroundings without being controlled. Since the fuel leak 20 is definitely discharged, the fuel leak 20 can be detected using a sensor not shown, and when the fuel leak 20 increases, a failure of the first safety valve 18 can be inferred.

ガス管１１が好適には気体の窒素で洗浄される第２駆動状態において、洗浄剤導管１３内の圧力上昇の結果、第１安全バルブ１８は、自動的に開き、他方第２安全バルブ１９は、自動的に閉じる。これによって、気体洗浄剤１４を第２駆動状態において確定的に運ぶことができ、当該気体洗浄剤１４が制御されることなく周囲に流出するのを回避できる。   In the second drive state, where the gas pipe 11 is preferably flushed with gaseous nitrogen, the first safety valve 18 opens automatically as a result of the pressure increase in the cleaning agent conduit 13 while the second safety valve 19 , Close automatically. Accordingly, the gas cleaning agent 14 can be definitely transported in the second driving state, and the gas cleaning agent 14 can be prevented from flowing out without being controlled.

図３は、ガスエンジンのための本発明に係る燃料供給・洗浄装置１０の具体的な実施例を示している。左側には、主流室１６と副流室１７とを定義する二重壁のガス管１１が示されている。右側には、一重壁の洗浄剤導管１３が示されている。バルブユニット１５は、ガス管１１と洗浄剤導管１３との間に配置されており、ガス管１１のフランジ２３とバルブユニット１５のフランジ２４との間に設けられている中間フランジ２２を介してガス管１１に作用する。   FIG. 3 shows a specific embodiment of a fuel supply and cleaning device 10 according to the invention for a gas engine. On the left side, a double-walled gas pipe 11 defining a main flow chamber 16 and a subflow chamber 17 is shown. On the right, a single wall detergent conduit 13 is shown. The valve unit 15 is disposed between the gas pipe 11 and the cleaning agent conduit 13, and gas is supplied via an intermediate flange 22 provided between the flange 23 of the gas pipe 11 and the flange 24 of the valve unit 15. Acts on the tube 11.
