Description

本発明は、自動車の燃料として実用化されつつある水素ガス、天然ガス（ＣＮＧ）等の高圧ガスを充填する高圧ガス充填装置に関する。   The present invention relates to a high-pressure gas filling apparatus that fills high-pressure gas such as hydrogen gas and natural gas (CNG) that is being put into practical use as fuel for automobiles.

石油の枯渇及び環境問題から、天然ガスを燃料とする内燃機関で駆動される自動車が普及しつつある。また、内燃機関に代わって、水素ガスを燃料とする燃料電池で発電された電力で駆動される自動車の期待が高まりつつある。そして、これらのガスを自動車へ充填する高圧ガス充填装置の普及が望まれている。   Due to the depletion of oil and environmental problems, automobiles driven by internal combustion engines using natural gas as fuel are becoming popular. Further, instead of an internal combustion engine, the expectation of an automobile driven by electric power generated by a fuel cell using hydrogen gas as fuel is increasing. And the spread of the high-pressure gas filling apparatus which fills these gases to a motor vehicle is desired.

水素ガス及び天然ガスは、高圧（例えば水素ガスは７０ＭＰａ）で充填されるために、機器の少しの破損でも大量にガスが洩れ出す虞がある。そして、これらのガスは空気より軽く、ハウジングの上部内に溜まりやすく、引火し易いために爆発事故を起こす危険性が高い。   Since hydrogen gas and natural gas are filled at a high pressure (for example, hydrogen gas is 70 MPa), there is a possibility that a large amount of gas leaks even if the equipment is slightly damaged. These gases are lighter than air, tend to accumulate in the upper part of the housing, and easily ignite, so there is a high risk of causing an explosion accident.

そこで本出願人は、ハウジングの上部に通気用のスリットを開け、ハウジング内にガスが溜まらないようにした高圧ガス充填装置を提案している（特許文献１）。この提案は有効であるが、ガスをハウジングから大気中へ直接放出するので、ガスに引火して爆発事故を起こす危険性がある。
特開２００４−１９７９４号 In view of this, the present applicant has proposed a high-pressure gas filling device in which a ventilation slit is formed in the upper portion of the housing so that gas does not accumulate in the housing (Patent Document 1). Although this proposal is effective, since the gas is released directly from the housing into the atmosphere, there is a risk of igniting the gas and causing an explosion.
JP 2004-19794

本発明は上記に鑑みてなされたもので、機器が破損してガスが洩れた場合に、ガスを安全な場所へ強制的に排出し、爆発事故等が未然に防止できる高圧ガス充填装置を提供することを目的としている。   The present invention has been made in view of the above, and provides a high-pressure gas filling device capable of forcibly discharging gas to a safe place and preventing an explosion accident or the like when an instrument breaks and gas leaks. The purpose is to do.

本発明によれば、引火し易い高圧ガスを充填するためにハウジング（１２）内に導入した充填管（１１）に流量計（１３）を介装し、ハウジング（１２）外へ導出した充填管（１１）に充填ホース（１５）を介して充填ノズル（１６）を設け、流量計（１３）で計量された充填量を表示する表示器（３１）を設けた高圧ガス充填装置において、ハウジング（１２）の上部に接続した排気管（７）を非危険場所に開口した放出管（８）に接続し、そして前記ハウジング（１２）にガスセンサ（４２）及び感震センサ（４３）を設け、前記排気管（７）に換気手段（３５）を設け、前記ハウジング（１２）内へ導入した充填管（１１）に遮断弁（４）を設け、ガスセンサ（４２）又は感震センサ（４３）の信号を受けて換気手段（３５）を駆動し、遮断弁（４）を閉じる制御装置（４４）を設けている。   According to the present invention, the filling pipe (11) introduced into the housing (12) in order to fill the flammable high-pressure gas is provided with the flow meter (13), and the filling pipe led out of the housing (12). In the high-pressure gas filling apparatus provided with a filling nozzle (16) through a filling hose (15) in (11) and provided with an indicator (31) for displaying the filling amount measured by the flow meter (13), 12) An exhaust pipe (7) connected to the upper part of 12) is connected to a discharge pipe (8) opened in a non-hazardous area, and a gas sensor (42) and a seismic sensor (43) are provided in the housing (12), A ventilation means (35) is provided in the exhaust pipe (7), a shutoff valve (4) is provided in the filling pipe (11) introduced into the housing (12), and a signal from the gas sensor (42) or the seismic sensor (43) is provided. To drive the ventilation means (35) Close the shutoff valve (4) the control device (44) is provided.

ここで非危険場所とは法令で定められている安全な場所であり、例えばガス洩れにより点火や着火しない離れた位置を云い、その安全な場所で大気開放するようになっている。   Here, the non-hazardous place is a safe place stipulated by laws and ordinances. For example, a non-hazardous place is a remote location where no ignition or ignition occurs due to gas leakage, and the atmosphere is opened to the safe place.

また、前記排気管７に不活性ガス供給手段３６を設け、前記制御装置４４で不活性ガス供給手段３６の供給を制御している。   Further, an inert gas supply means 36 is provided in the exhaust pipe 7, and the supply of the inert gas supply means 36 is controlled by the control device 44.

（１） ガスをハウジングから大気中へ直接放出することなく、安全な場所に開口した放出管から放出しているので、引火の危険性がなく安全である。
（２） 非常時にはハウジング内を強制的に排気しているので、洩れたガスを確実に排気できて安全である。
（３） 充填管に設けた遮断弁を閉じるので、ガス洩れを最小限に押さえることができる。
（４） 不活性ガスで希薄して排気しているので、大気中へ放出されるガスが引火爆発する危険が少なくなるので安全である。 (1) Since the gas is discharged from the discharge pipe opened in a safe place without directly releasing the gas from the housing into the atmosphere, there is no risk of ignition and it is safe.
(2) Since the inside of the housing is forcibly exhausted in an emergency, the leaked gas can be surely exhausted and it is safe.
(3) Since the shutoff valve provided in the filling pipe is closed, gas leakage can be minimized.
(4) Since the exhaust gas is diluted with an inert gas and exhausted, the risk of flammable explosion of the gas released into the atmosphere is reduced.

次に、本発明の高圧ガス充填装置５によるガス充填の態様を説明する。
蓄圧器３内には、圧縮機２で８０ＭＰａ程度の高圧に加圧されたガスが蓄圧されている。自動車へ高圧ガスを充填するには、ノズル掛け１７から外した充填ノズル１６を自動車の燃料タンクへ接続しておこなう。 Next, an aspect of gas filling by the high-pressure gas filling device 5 of the present invention will be described.
In the pressure accumulator 3, the gas pressurized to a high pressure of about 80 MPa by the compressor 2 is accumulated. In order to fill the automobile with high-pressure gas, the filling nozzle 16 removed from the nozzle hook 17 is connected to the fuel tank of the automobile.

ノズル掛け１７から充填ノズル１６を外すと、ノズルスイッチ１８から制御装置３０へ信号が伝わり、制御装置３０は表示器３１に表示されていた前回の充填量を帰零し、遮断弁４、１４を開く。   When the filling nozzle 16 is removed from the nozzle hook 17, a signal is transmitted from the nozzle switch 18 to the control device 30, the control device 30 returns the previous filling amount displayed on the display 31, and the shutoff valves 4 and 14 are turned on. open.

遮断弁４、１４が開くことにより、蓄圧機３内の高圧ガスは遮断弁４、流量計１３、遮断弁１４、及び充填ホース１５を介して充填ノズル１６から自動車の燃料タンクへ充填される。そして、制御装置３０は、流量計１３の信号から充填量を演算し、充填量を表示器３１に表示する。   When the shut-off valves 4 and 14 are opened, the high-pressure gas in the pressure accumulator 3 is filled into the automobile fuel tank from the filling nozzle 16 via the shut-off valve 4, the flow meter 13, the shut-off valve 14, and the filling hose 15. Then, the control device 30 calculates the filling amount from the signal of the flow meter 13 and displays the filling amount on the display 31.

充填が終わり、停止スイッチ４５からの終了信号を受けて制御装置３０は遮断弁４、１４を閉じる。そして、脱圧弁２５を開き、チェック弁２６を押し開き、脱圧管２４及びガス抜き管６を介して放出管８ａから圧力を放出する。さらに、表示器３１に表示された充填量に基づいてガス充填の精算が行なわれる。   When the filling is finished, the control device 30 receives the end signal from the stop switch 45 and closes the shut-off valves 4 and 14. Then, the pressure release valve 25 is opened, the check valve 26 is pushed open, and the pressure is released from the discharge pipe 8 a through the pressure release pipe 24 and the gas vent pipe 6. Further, the gas filling is settled based on the filling amount displayed on the display 31.

機器の異常又は待機中の気温上昇等で充填管１１内が異常高圧になった場合は、安全弁２８が開き、チェック弁２９が押し開かれ、脱圧管２７及びガス抜き管６を介して放出管８ａから圧力が放出される。   When the inside of the filling pipe 11 becomes abnormally high due to an abnormality in the equipment or a rise in temperature during standby, the safety valve 28 is opened, the check valve 29 is pushed open, and the discharge pipe is connected via the pressure reducing pipe 27 and the gas vent pipe 6. Pressure is released from 8a.

流量計１３が損傷してガス洩れが生じた場合は、密閉室１９内が高圧になって破裂板２１が壊れ、チェック弁２２が押し開かれ、密閉室１９内のガスは脱圧管２０及びガス抜き管６を介して放出管８ａから放出される。   When the gas meter 13 is damaged due to damage to the flow meter 13, the inside of the sealed chamber 19 becomes high pressure, the rupture plate 21 is broken, the check valve 22 is pushed open, and the gas in the sealed chamber 19 is depressurized pipe 20 and gas. It is discharged from the discharge pipe 8a through the extraction pipe 6.

同時に、破裂センサ２３から制御装置３０へ信号が伝わり、制御装置３０は遮断弁４、１４を閉じてガス洩れを最小限に押さえ、制御装置４４へ異常信号を出力し、報知器３２を作動して異常を知らせる。   At the same time, a signal is transmitted from the burst sensor 23 to the control device 30, and the control device 30 closes the shut-off valves 4 and 14 to minimize gas leakage, outputs an abnormal signal to the control device 44, and activates the alarm 32. To inform you of any abnormalities.

次に、機器の破損によりガスが洩れてガスセンサ４２が検知した場合、及び地震又は事故の衝撃等で感震センサ４３が検知した場合の制御の態様を、図３のフロー図に基づいて説明する。   Next, the control mode when gas sensor leaks due to equipment breakage and gas sensor 42 detects it, and when seismic sensor 43 detects it due to the impact of an earthquake or accident, etc., will be described based on the flow diagram of FIG. .

ガスセンサ４２又は感震センサ４３から危険信号が制御装置４４に伝わり、制御装置４４が危険状態と判断すると報知器３２を作動し（ＳＴ１）、制御装置４４は制御装置３０へ異常信号を送り、制御装置３０は遮断弁４、１４を閉じる（ＳＴ２）。   A danger signal is transmitted from the gas sensor 42 or the seismic sensor 43 to the control device 44, and when the control device 44 determines that it is in a dangerous state, the alarm device 32 is activated (ST1), and the control device 44 sends an abnormal signal to the control device 30 for control. The device 30 closes the shut-off valves 4 and 14 (ST2).

遮断弁４、１４が閉じることにより充填不能状態となり、安全弁２８が開くことにより充填管１１内のガスが放出管８ａから放出され、報知器３２が作動して安全が確保される。   When the shut-off valves 4 and 14 are closed, the filling becomes impossible, and when the safety valve 28 is opened, the gas in the filling pipe 11 is released from the discharge pipe 8a, and the alarm 32 is activated to ensure safety.

同時に制御装置４４は、換気手段３５を駆動して遮断弁３８を開く（ＳＴ３）。換気手段３５が駆動されることによりハウジング１２内は強制的に排気され、遮断弁３８が開くことにより不活性ガス供給手段３６の不活性ガスが排気管７内に供給され、不活性ガスで希薄されて安全となったガスが放出管８ｂから放出される。   At the same time, the controller 44 drives the ventilation means 35 to open the shutoff valve 38 (ST3). When the ventilation means 35 is driven, the inside of the housing 12 is forcibly evacuated, and when the shut-off valve 38 is opened, the inert gas of the inert gas supply means 36 is supplied into the exhaust pipe 7 and is diluted with the inert gas. The gas that has been made safe is discharged from the discharge pipe 8b.

なお、圧縮機２の駆動も停止し、充填所の安全を確保する。
ガス濃度が正常に戻ったら（ＳＴ４）、作業員は安全を確認して停止スイッチ４５を押すと（ＳＴ５）、排気管７内の残留ガスが放出管８ｂから完全に放出されるであろう一定時間、例えば２分後に（ＳＴ６）、換気手段３５が停止し、遮断弁３８が閉じる（ＳＴ７）。 The driving of the compressor 2 is also stopped to ensure the safety of the filling station.
When the gas concentration returns to normal (ST4), when the worker confirms safety and presses the stop switch 45 (ST5), the residual gas in the exhaust pipe 7 will be completely discharged from the discharge pipe 8b. After a time, for example, 2 minutes (ST6), the ventilation means 35 is stopped and the shutoff valve 38 is closed (ST7).

そして、高圧ガスの充填所の各機器の安全を点検し、全てが安全であることを確認した後に、営業を再開する。   And after checking the safety of each apparatus of the high-pressure gas filling station and confirming that everything is safe, the business is resumed.

なお、高圧ガス充填装置５で使用されている各機器は、危険ガス中でも安全に使用できる防爆タイプのものが用いられている。   The devices used in the high-pressure gas filling device 5 are explosion-proof types that can be used safely even in hazardous gases.

地震及び事故等の非常時の安全を確保した高圧ガス充填装置が提供でき、高圧ガス充填装置の普及が促進され、高圧ガスで走行する自動車の普及が促進されるようになる。   A high-pressure gas filling device that ensures safety in an emergency such as an earthquake or an accident can be provided, and the spread of the high-pressure gas filling device is promoted, and the spread of automobiles that run on high-pressure gas is promoted.
