  FIG. 1 is an explanatory view showing an embodiment of a disaster prevention facility for a hydrogen station according to the present invention.

  In FIG. 1, in the hydrogen station 1 in this embodiment, a gas station 2 is provided adjacently, and a stand office building 3 is further provided. In the hydrogen station 1, a liquid hydrogen tank 4, an evaporator 5, a compressed hydrogen tank 6, and a hydrogen gas filling device 7 are installed.

  Liquid hydrogen carried from the outside is stored in the liquid hydrogen tank 4. The liquid hydrogen is converted into hydrogen gas by the evaporator 5 and stored in the compressed hydrogen tank 6. The hydrogen gas in the compressed hydrogen tank 6 is converted into hydrogen. The gas filling device 7 supplies the fuel cell vehicle and the like. There is also a type in which the compressed hydrogen tank 6 stores liquid hydrogen and fills the fuel cell vehicle with liquid hydrogen. On the other hand, a fueling device 8 is installed on the gas station 2 side.

  As described above, as a disaster prevention facility for the hydrogen station 1 provided along with the gas station 2, a jet liquid tank 9 storing a jet liquid is provided. As the jet liquid tank 9, for example, a water source water tank is used. A suction pipe of a pump 11 driven by a motor 10 is lowered with respect to the spray liquid tank 9.

  The motor 10 is driven by a pump control panel 12. The discharge side of the pump 11 is connected to the injection liquid pipe 14, and the injection liquid pipe 14 is connected to the equipment of the hydrogen station 1 and the equipment of the gas station 2 through a branch pipe.

  In this embodiment, the hydrogen station 1 is divided into two systems, that is, the hydrogen gas filling device 7 side and other equipment, and the injection liquid pipe 14 is branched, and further, the fuel supply device 8 side of the gas station 2 The injection liquid pipe 14 is branched independently. A priming tank 13 is installed on the discharge side of the pump 11.

  An injection head 18 is provided in the injection liquid pipe 14 installed in the hydrogen station 1. Here, the injection liquid pipes 14 for the liquid hydrogen tank 4, the evaporator 5 and the compressed hydrogen tank 6 are piped in a state where they are set up at positions where each equipment is looked down from above, and pipes arranged at this high position. The jet head 18 is installed facing the equipment.

  On the other hand, the hydrogen gas filling device 7 is provided with an injection liquid pipe 14 on the installation surface side, toward the hydrogen gas filling apparatus 7 side and the stop position at the leading end of the rising pipe from the injection liquid pipe 14. An ejection head 18 is installed.

  As for the fueling device 8 and the stop position of the gas station 2, the injection head 18 is installed downward after the injection liquid pipe 14 is raised upward.

  Control valves 15 a, 15 b, and 15 c are provided at the branch portions of the two injection liquid pipes 14 for the hydrogen station 1 and the branch portions for the gas station 2, respectively. The secondary sides of the control valves 15a to 15c are branched to the jet head 18 side, and are branched and connected to the opposite drain pipe side via test valves 16a, 16b, and 16c.

  The control valves 15 a to 15 c are connected to a signal line 28 from the control device 19. A hydrogen detection device 25 installed on the hydrogen station 1 side is connected to a signal line 28 from the control device 19, and a fire detection device 26 installed on the gas station 2 side is further connected. Further, push buttons 27a, 27b, 27c, and 27d installed on the hydrogen station 1 and the gas station 2 side are connected to the signal line 28.

  Here, the signal line 28 is divided into a control signal line for the control valves 15a to 15c and a detection signal line for the hydrogen detection device 25, the fire detection device 26, and the push buttons 27a to 27d.

  Furthermore, a fire receiver 22 is installed in the stand office building 3, and a fire detector 24 is connected to a sensor line 23 drawn from the fire receiver 22. The fire receiver 22 is connected to the control device 19 through a signal line 21 and sends a fire report signal to the control device 19 when a fire detection signal from the fire detector 24 is received. The hydrogen detection device 25 and the fire detection device 26 may be connected to the fire receiver 22, and hydrogen or fire detection signals may be sent to the control device 19 via the fire receiver 22.

  Furthermore, in this embodiment, the stock solution tank 31 and the mixer 32 are provided on the primary side of the control valve 15c provided on the gas station 2 side, and for fire extinguishing mainly composed of a foam fire-extinguishing agent and a synthetic surfactant. The stock solution is stored and mixed with water sent from the jet liquid tank 9 by the pump 11 at a predetermined ratio so that the foam extinguishing agent can be jetted from the jet head 18.

  A pressure tank 29 is provided for the injection liquid pipe 14 between the pump 11 serving as a pressure supply device and the control valves 15a to 15c. The pressure switch is used to compress the air in the tank by introducing pressurized water. The contact of the starting pressure switchgear 30 is opened.

  When the control valves 15a to 15c are controlled to be opened, and the pressure of the pressurized water in the injection liquid pipe 14 is reduced by the injection from the injection head 18, the contact of the activation pressure switch 30 is closed and an activation signal is sent to the pump control panel 12. Start the pump.

  Next, the disaster prevention processing operation in the embodiment of FIG. 1 will be described. For example, if a fire has occurred in or near the stand office building 3, the fire detector 24 near the fire occurrence site is notified, and the fire receiver 22 receives the fire signal from the fire detector 24 and fires. At the same time as alarming, a fire transfer signal is sent to the control device 19.

  The control device 19 that has received the fire transfer signal from the fire receiver 22 sends a control signal to each of the control valves 15a, 15b, and 15c to perform open control. Here, in the normal monitoring state, the control valves 15a, 15b, and 15c are closed and the primary injection liquid pipe 14 is filled with predetermined pressurized water.

  For this reason, when the control valves 15a, 15b and 15c are controlled to open, the internal pressure of the injection liquid pipe 14 from the pump 11 to the control valves 15a to 15c decreases, and the internal pressure of the pressure tank 29 also decreases at the same time. The pressure switch 30 is operated in response to a pressure drop and outputs a pump start signal to the pump control panel 12.

  For this reason, the pump control panel 12 starts the pump 11 by the motor 10, and the water from the jet liquid tank 9 is jetted by being pressurized and supplied to the jet head 18 installed in the hydrogen station 1 and the gas station 2, The liquid hydrogen tank 4, the evaporator 5, the compressed hydrogen tank 6, the hydrogen gas filling device 7, the fueling device 8, and the stop water are sprayed to the hydrogen station 1 and the gas station from the fire heat generated in the stand office building 3. Protect equipment on the two sides.

  The amount of water jetted by the jet head 18 in this case is set so that the amount of water jetted is equal to or greater than the amount of water having the latent heat of vaporization of water equivalent to the heat-receiving heat flow assumed in advance in the device to be protected. Moreover, as a setting of the amount of water jetted from the jet head 18, you may set a water flow rate so that the effect | action which interrupts this with respect to the thermal radiation flow with respect to a protection target apparatus may be implement | achieved.

  Here, a stock solution tank 31 and a mixer 32 are provided on the primary side of the control valve 15 c provided in the system of the gas station 2. For this reason, the effervescent medicine in the stock solution tank 31 is added to the water from the pump 11. The mixture is mixed by the mixer 32 at a ratio, so that the water from the injection liquid tank 9 becomes a foamable aqueous solution, is discharged from the injection head 18, and includes a foam suitable for protection of gasoline handled by the fueling device 8. Is done.

  In order to protect the refueling device 8 from heat from a fire in another place, only water injection may be used. However, when the refueling device itself becomes a source of fire, it is difficult to extinguish only by water injection. Therefore, in this embodiment, the foaming aqueous solution is made by the mixer 32 and ejected from the ejection head 18 to the oil supply device 8.

  FIG. 2 is a flowchart showing the processing operation of the disaster prevention control process by the control device 19 of FIG. In the disaster prevention control processing by the control device 19, the presence or absence of abnormality detection is monitored in step S1, a fire report signal from the fire receiver 22, a hydrogen detection device 25 installed in the hydrogen station 1, gasoline When the detection signal of the fire detection device 26 installed in the stand 2 or any one of the push buttons 27a to 27d is received, the process proceeds to step S2 with an abnormality detected.

  In the process of step S2, the control valve corresponding to the abnormality detection section is basically opened, but in the embodiment of FIG. 1, the three systems provided in the hydrogen station 1 and the gas station 2 are used. The control valves 15a to 15c are controlled to open simultaneously.

  Thus, the operation of the pump 11 is automatically controlled, the injection liquid is pressurized and supplied from the injection liquid tank 9, and is injected from the injection head 18 to the protection target device, and the equipment to be protected is cooled and injected by evaporation of the injection liquid. The heat radiation flow is blocked by the liquid. At this time, the supply of fuel from the hydrogen gas filling device 7 and the fuel supply device 8 is stopped.

  When a fire recovery confirmation signal is obtained in step S3, the process proceeds to step S4, a recovery process for closing the control valve and returning the control device 19 to the initial state is performed, and the series of disaster prevention control processes is completed.

  As the disaster prevention control processing by the control device 19, a switch for automatic operation and manual operation is provided in the control device 19, and it is set to manual when there is an attendant, and automatically switched at night when there is no attendant.

  When the changeover switch of the control device 19 is manually operated, the control processing of the control device 19 is started by manual operation of the push buttons 27a to 27d provided in the hydrogen station 1, the gas station 2 or the stand office building 3. Thus, the ejection liquid is discharged from the ejection head 18.

  In addition, as the spray liquid in the spray liquid tank 9, water-soluble polymer typified by locust bin gum, mannan, starch, carboxymethyl cellulose or the like is mixed in advance, and the viscosity of the spray water is increased. By spraying the protection object from the head 18, the flow-down speed of the spray liquid sprayed to the protection object can be slowed, thereby increasing the efficiency of thermal protection.

  Such a process for increasing the viscosity of the injection liquid is performed on the primary side of the control valves 15a and 15b in the system on the hydrogen station 1 side as well as the raw liquid tank 31 and the mixer 32 provided on the gas station 2 side. Install a tank and a mixer, store the foaming chemical in the stock tank and mix it with the mixer to create a highly viscous stock solution and inject it from the jet head 18 on the hydrogen station 1 side onto the object to be protected. Also good.

  Further, for the hydrogen station 1 installed in a cold region, in order to prevent the spray liquid from freezing, an antifreeze liquid typified by ethylene glycol or the like is put into the stock liquid tank provided for the spray liquid tank 9 or the mixer. You may do it.

  Furthermore, as foaming stock solution mixed with a mixer from a stock solution tank provided on the hydrogen station 1 side, a foam extinguishing agent used in so-called mechanical foam for fire extinguishing, or a fire extinguishing stock solution mainly composed of a synthetic surfactant is used. It can also be used.

  Furthermore, as the ejection head 18 used in the embodiment of FIG. 1, the ejection pattern may be any of a flat type, a full cone type, a holo cone type, etc., or a head with a foaming mechanism such as a net. Furthermore, the installation position is not limited to the upper side or the lower side, and may be an appropriate position at which effective radiation is obtained. Moreover, it is preferable that the abnormality detectors such as the fire detector 24, the hydrogen detector 25, and the fire detector 26, and the electrical equipment such as the controller 19 have an explosion-proof function.

  FIG. 3 is an explanatory view showing another embodiment of the hydrogen station protective equipment according to the present invention, which is intended for a hydrogen station installed alone and is a relatively simple disaster prevention equipment. .

  In FIG. 3, a liquid hydrogen tank 4, an evaporator 5, a compressed hydrogen tank 6, and a hydrogen gas filling device 7 are installed in the hydrogen station 1, and an injection liquid pipe 14 from the injection liquid tank 9 side is provided. The injection liquid pipe 14 is installed on the lower side with respect to the hydrogen gas filling device 7 and the stop position side, is started up at the portion of the hydrogen gas filling device 7, and an injection head 18 is installed there.

  On the other hand, on the liquid hydrogen tank 4, the evaporator 5 and the compressed hydrogen tank 6 side, a water cannon device 34 is installed, and the device to be protected is cooled by the spray from the water cannon 34 a of the water cannon device 34 and the heat generated by water radiation. The radiation flow is cut off.

  Further, a submersible pump 33 is installed in the spray liquid tank 9 as a pressure supply device, and the operation control of the submersible pump 33 is performed by the control device 19. The control device 19 is provided with a seismic device 20, and the signal line 21 from the control device 19 has a hydrogen detector 25 installed at the hydrogen station and a push installed at the stand office building 3 and the hydrogen station 1 side. A button 27 is connected.

  In the embodiment shown in FIG. 3, when a fire occurs in the vicinity of the hydrogen station 1, for example, in the vicinity of the stand office building 3, the control device 19 detects the abnormality by pressing the push button 27 by the attendant. A signal is input, and thereby the submersible pump 33 is operated, and water from the jet liquid tank 9 is pressurized and supplied to the hydrogen station 1 side through the jet liquid pipe 14.

  The pressurized jet liquid is discharged from the jet head 18 on the hydrogen gas filling device 7 side, while water is discharged from the water gun device 34 on the liquid hydrogen tank 4, the evaporator 5 and the compressed hydrogen tank 6 side. The device to be protected is protected from fire by cooling by evaporating line heat by spraying the spray liquid onto the fireproof object against the heat flow received by the fire and blocking the amount of heat radiation by the spray liquid.

  Also in this case, the flow rate of the spray liquid adhering to the sprayed protection object is decreased by mixing water-soluble polymer in the water of the spray liquid tank 9 in advance and increasing the viscosity of the spray water. It is desirable to increase the efficiency of thermal protection.

  Moreover, since the water cannon device 34 can rotate the water cannon and move up and down, the person in charge adjusts the water discharge direction by the water cannon device 34 as necessary, and the protection target corresponding to the fire situation at that time Can be appropriately discharged.

  Further, the submersible pump 33 used as the pressure supply device in this embodiment has a discharge pressure that is not so high as compared with the pump 11 of FIG. 1, but the injection head 18 and the water spray gun device 34 of the hydrogen station 1. Since a building is installed at a level corresponding to the first floor, even if it is the discharge pressure of the submersible pump 33, it is possible to discharge a sufficient amount of jetting liquid.

  Even in the embodiment of FIG. 3, since the seismic device 20 and the hydrogen detection device 25 are provided in the control device 19, leakage of hydrogen gas is detected by a detection signal from the seismic device 20 when an earthquake occurs. The control device 19 automatically controls the operation of the submersible pump 33 with the detection signal from the hydrogen detection device 25, and the radiant liquid is injected from the injection head 18 and the water spray gun device 34.

  FIG. 4 is an explanatory view showing another embodiment of the protection equipment for the hydrogen station according to the present invention. As in the embodiment of FIG. 3, a simple disaster prevention equipment is taken as an example. It is characterized in that tap water is used instead of the spray tank.

  In FIG. 4, the equipment on the hydrogen station 1 side, the jet head 18, and the water spray gun device 34 are the same as those in the embodiment of FIG. 3, but no pressure supply device for the jet liquid pipe 14 is provided. The pipe 14 is connected to the water pipe 35 through the control valve 15 and the dead water prevention joint 36.

  The control valve 15 provided at the connection portion of the jet liquid pipe 14 to the water pipe 35 has a three-way valve structure that drains the secondary side water when closed, so that the stagnant water does not flow back to the water side. The controller 19 controls the opening and closing. The signal line 21 drawn from the control device 19 is connected to a hydrogen detector 25 provided in the hydrogen station 1 and further connected to a push button 27 provided in the hydrogen station 1 and the stand office building 3.

  In this embodiment, for example, when a fire occurs in the stand office building 3 or the like, an abnormality detection signal is given to the control device 19 by the signal line 21 when the attendant presses the push button 27, and the control device 19 19 opens the control valve 15.

  For this reason, the tap water from the water pipe 35 is sent to the hydrogen station 1 side through the jet pipe 14 through the control valve 15 and is jetted from the jet head 18 to the hydrogen gas filling device 7, and at the same time from the water spray gun device 34. The liquid hydrogen tank 4, the evaporator 5 and the compressed hydrogen tank 6 are discharged.

  Of course, in addition to the operation of the push button 27 by a staff member at the time of a fire, the hydrogen detector 25 detects hydrogen and outputs an abnormal signal when hydrogen gas leaks from the hydrogen gas filling device 7 provided in the hydrogen station 1. In this case, similarly, the control device 19 opens the control valve 15 to supply the tap water from the water pipe 35, inject the tap water to the hydrogen station 1, and protect the device by the heat receiving heat flow caused by the fire. The thermal radiation flow is blocked by cooling the water and jetting tap water. At the time of restoration, when the control valve 15 is controlled to be closed, the injection liquid pipe 14 is connected to the drain pipe so that it does not flow backward to the water pipe 35 side.

  The hydrogen station to which the disaster prevention equipment of the present invention is applied is not limited to equipment that stores liquid hydrogen and converts it to liquid hydrogen or hydrogen gas, and supplies it to fuel cell vehicles, etc. In some cases, it may include a facility for generating hydrogen from gasoline or the like, and can be applied as it is to a hydrogen station having an appropriate facility configuration.

Further, the protective equipment of the present invention can take an appropriate configuration as long as it is configured to pressurize and supply the injection liquid and inject it to the device to be protected of the hydrogen station 1.
