Description

  The present invention relates to a gas supply device provided in a hydrogen supply station or the like for supplying hydrogen gas as fuel to a fuel cell vehicle or the like, and a gas supply method using the gas supply device. More specifically, the present invention relates to a gas supply device and a gas supply method for storing compressed gas in a storage tank and supplying the compressed gas with a dispenser.

  For example, a hydrogen supply station for supplying hydrogen gas to a fuel cell vehicle has a hydrogen production apparatus for producing hydrogen from city gas and the like, and a gas supply apparatus for supplying the produced hydrogen. Yes. The gas supply device includes a gas storage device for compressing and storing the hydrogen produced by the hydrogen production device, and a tank (vehicle tank) in which the gas stored in the gas storage device is mounted on a fuel cell vehicle or the like And a dispenser for supplying to the device. In general, hydrogen produced by a hydrogen production apparatus is pressurized to a predetermined pressure or higher (for example, 40 MPaG) by a compressor and temporarily stored in a gas storage device. The on-vehicle tank of the fuel cell automobile is filled with hydrogen by a dispenser until a predetermined pressure (for example, 35 MPaG) is reached.

  Generally, when filling a container with high-pressure gas, it can be considered that adiabatic compression of the gas occurs in the container, so that the gas temperature in the container rises. A similar phenomenon occurs when filling an on-vehicle tank of a fuel cell vehicle with the hydrogen gas, so that the gas temperature in the on-vehicle tank rises and the temperature of the on-vehicle tank itself rises accordingly. On the other hand, in-vehicle tanks may be partially made of a material with slightly low heat resistance such as resin, and therefore the temperature range allowed for in-vehicle tanks is set to, for example, -40 to 82 ° C. ing.

  Conventionally, when hydrogen gas is filled in an on-vehicle tank of a fuel cell vehicle, the flow control valve in the dispenser is automatically controlled. For example, the control method is as follows. First, the flow control valve is opened to a predetermined opening at a predetermined speed, and filling is continued while maintaining the opening. Then, the flow control valve is closed when the in-vehicle tank approaches a full tank state and reaches the set supply amount or set pressure. However, when the valve opening is increased and hydrogen is rapidly filled, the temperature of the on-vehicle tank may become higher than the allowable range due to the increase in gas temperature. Therefore, in the conventional gas supply device, the temperature rise is suppressed by limiting the flow rate or pressure of hydrogen filling the on-vehicle tank to a certain extent.

On the other hand, a filling method is proposed in which filling is started at a sufficiently low initial speed and the gas flow rate is gradually increased (see, for example, Patent Document 1). According to the filling method of this document, when an empty container is filled, gas is slowly introduced to prevent excessive heating of the gas container. Further, after the gas flow rate is increased, when the filling amount approaches the predetermined amount, the gas flow rate is gradually decreased to accurately fill the predetermined gas amount.
Japanese Patent Laid-Open No. 10-318496

  However, the conventional gas supply method described above has the following problems. First, the method of limiting the flow rate of the gas to be filled is not preferable because it takes a long time to fill the on-vehicle tank of the automobile. In addition, if the gas pressure is limited, the ultimate gas pressure in the on-vehicle tank is lowered, and the amount of gas that can be filled is reduced. Further, in the method of changing the gas flow rate as in Patent Document 1, the gas flow rate is constantly changing, so that measurement and control are difficult. In addition, unlike gas cylinders that always start filling from an empty state, in-vehicle tanks for fuel cell vehicles may start filling from a state where some gas remains, so it is difficult to accurately control the filling speed. There was a problem that there was.

  The present invention has been made to solve the problems of the conventional gas supply apparatus described above. That is, an object of the present invention is to provide a gas supply device and a gas supply method capable of filling a gas in a short time while suppressing the maximum temperature reached by the in-vehicle tank.

  The gas supply device of the present invention made for the purpose of solving this problem is a gas supply device having a gas storage container and a dispenser for supplying the gas stored in the gas storage container to a supply destination container. And an opening control unit for controlling the opening of the opening adjustment valve. The opening control unit is opened at the initial stage of supply to the supply destination container. The degree adjustment valve is set to the first opening to perform low-speed supply, and then the opening adjustment valve is switched to the larger second opening to perform rapid supply.

  According to the gas supply device of the present invention, when the gas stored in the gas storage container is supplied to the supply destination container, the gas flow rate is adjusted by the opening of the opening adjustment valve. The opening of the opening adjusting valve is adjusted by the opening control unit, and is supplied at a low speed with the first opening at the initial stage of supply, so even if the supply destination container is nearly empty, the gas temperature The rise is suppressed. Thereafter, since the gas is supplied rapidly at the second opening, gas can be charged in a short time.

  Here, the relationship between the gas flow rate supplied to the supply destination container and the gas temperature is as follows. In the low gas flow rate region, the lower the gas flow rate, the lower the gas temperature increase rate. In the high gas flow rate region, the gas temperature increase rate is almost constant regardless of the gas flow rate. Further, during the process of supplying the gas to the supply destination container, the temperature rise of the gas does not continue, but the temperature of the previously supplied gas is lowered by the heat radiation to the surroundings. For this reason, heat is dissipated by taking a long supply time at a small flow rate at the beginning of the supply process, and a short supply time at a large flow rate at the latter stage of the supply process. Thereby, since the increase range of gas temperature can be suppressed small as a whole of a supply process, the highest ultimate temperature of a supply destination container is suppressed. Therefore, the gas supply device is capable of filling the gas within a certain time while suppressing the maximum temperature reached by the on-vehicle tank.

Furthermore, in the present invention, there is a remaining amount acquisition means for acquiring information relating to the gas amount of the supply destination container, and the opening degree control unit is low speed only when the gas amount of the supply destination container before the start of supply is lower than a predetermined level. It is desirable to supply. Furthermore, it is desirable to switch to rapid supply when the amount of gas in the supply destination container reaches a predetermined level during low-speed supply.
In a case where the supply destination container is an in-vehicle tank or the like, it is not always in an almost empty state when the gas supply device receives gas supply. In this way, when the remaining amount of gas in the supply destination container is large to some extent, the gas is supplied rapidly from the beginning, and the gas can be filled in a shorter time. Further, if the minimum amount of gas that does not cause a problem even if rapidly supplied is set to a predetermined level, the gas can be charged in a short time while suppressing the maximum temperature reached in the supply destination container.

  The present invention also provides a gas supply method for supplying gas stored in a gas storage container to a supply destination container via a dispenser, wherein an opening degree adjusting valve is provided in a gas flow path in the dispenser, and the supply destination In the gas supply method, the opening adjustment valve is set to the first opening at the initial stage of supply to the container to perform low-speed supply, and then the opening adjustment valve is switched to a larger second opening to perform rapid supply. It also extends.

  Furthermore, in the present invention, there is provided a remaining amount acquisition means for acquiring information related to the gas amount in the supply destination container, and the low-speed supply is performed only when the gas amount in the supply destination container before the start of supply is lower than a predetermined level. It is desirable to switch to the rapid supply when the gas amount in the supply destination container reaches a predetermined level during the supply.

  According to the gas supply device and the gas supply method of the present invention, it is possible to fill the gas in a short time while suppressing the maximum temperature reached by the vehicle-mounted tank.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the best mode for embodying the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, the present invention is applied to a gas supply device used in a hydrogen supply station for supplying hydrogen gas to a fuel cell vehicle.

  As shown in FIG. 1, the gas supply device 1 of the present embodiment is connected to a hydrogen production device 2 of a hydrogen supply station to receive supply of hydrogen gas, and supply hydrogen gas to an in-vehicle tank 4 of a fuel cell vehicle 3. It is for supply. The hydrogen gas produced by the hydrogen production device 2 is compressed by the compressor 5 and stored in the gas supply device 1.

  As shown in FIG. 1, the gas supply device 1 includes a gas storage device 11 and a dispenser 12. The gas accumulator 11 has a plurality of gas tanks 21, 22, and inflow and outflow on-off valves 23, 24, 25, 26 and pressure gauges 27, 28 are connected to each of them. In this figure, two gas tanks 21 and 22 are shown, but a larger number may be provided. These gas tanks 21 and 22 have the same configuration, but are used separately in use.

  The dispenser 12 is connected to the on-off valve 31, the mass flow meter 32, the flow rate control valve 33, and the pressure gauge 34 in the flow path, and can be connected to the vehicle-mounted tank 4 by a filling hose 35. Further, the dispenser 12 is provided with a control device 36, which receives the detection results of the pressure gauges 27, 28, 34 and the mass flow meter 32, and has the on-off valves 23-25, 31 and the flow rate control valve 33. Control.

  The hydrogen gas produced by the hydrogen production apparatus 2 is compressed to about 40 MPaG by the compressor 5, the on-off valve 23 or 25 is opened, and is temporarily stored in the gas tank 21 or 22 of the gas storage device 11. When the fuel cell vehicle 3 that wishes to fill with hydrogen gas arrives at this hydrogen station, a filling hose 35 is connected to the in-vehicle tank 4, and the in-vehicle tank 4 is filled with hydrogen gas from one of the gas tanks 21 and 22. The gas pressures in the gas tanks 21 and 22 are detected by pressure gauges 27 and 28, and after the fuel cell vehicle 3 is filled with hydrogen gas, the hydrogen gas is introduced from the hydrogen production apparatus 2 and controlled to an appropriate pressure.

  Here, the vehicle-mounted tank 4 at the start of filling is not necessarily in a nearly empty state, and for example, filling may be started from a state in which about half remains. In our experiments, it was found that the lower the residual pressure in the tank, the greater the temperature rise due to filling. It was also found that the higher the gas flow rate during filling, the greater the temperature rise.

  Therefore, the control device 36 of the gas supply device 1 of the present embodiment first detects the amount of gas remaining in the in-vehicle tank 4 of the fuel cell vehicle 3 that has visited for filling. For this purpose, the filling hose 35 is connected to the vehicle tank 4 with all the valves closed, the valve of the vehicle tank 4 is opened, and the residual gas pressure in the vehicle tank 4 is detected by the pressure gauge 34. At the same time, the total capacity of the in-vehicle tank 4 is acquired by receiving inputs such as the type of the fuel cell vehicle 3 and the type of the in-vehicle tank 4. Alternatively, the capacity of the vehicle-mounted tank 4 may be the capacity of the standard vehicle-mounted tank of that class upon receiving the input of the vehicle class. And the amount of residual gas is calculated | required from the capacity | capacitance of the vehicle-mounted tank 4, and residual gas pressure.

  As a result, when the residual gas amount is large, as shown in FIG. In this case, a relatively large amount of gas remains in the tank, and the temperature rise is not so great even if it is quickly filled quickly. On the other hand, when the remaining gas amount is small, as shown in FIG. 3, the gas flow rate is reduced and filling is started, and the filling speed is increased when the filling has progressed to some extent. In this case, sudden rapid filling is not preferable because the temperature rises very much. Therefore, it is possible to fill in a short time while preventing an excessive rise in the gas temperature by slowly filling until a predetermined filling amount is reached and then rapidly filling.

  The gas supply method by this gas supply apparatus 1 is demonstrated based on the flowchart of FIG. When the fuel cell vehicle 3 that receives gas filling arrives, the control device 36 starts this gas filling process. When this process is started, first, the capacity of the in-vehicle tank 4 is acquired. Moreover, the pressure of the vehicle-mounted tank 4 is acquired from the detection result of the pressure gauge 34 (S101). Subsequently, the amount of gas remaining in the in-vehicle tank 4 is obtained from the result of S101 (S102). And it is judged whether the gas amount calculated | required by S102 is more than predetermined amount (S103).

  If the remaining gas amount is equal to or greater than the predetermined amount (S103: Yes), there is no problem even if it is rapidly filled as it is. Therefore, the on-off valves 24 and 31 are opened, and the flow control valve 33 is opened to the rapid filling opening degree (S104). This stage corresponds to the period from time 0 to t1 in FIG. In FIG. 2, the valve is opened to the quick filling valve opening p1 at time t1. In this state, hydrogen gas is charged into the on-vehicle tank 4 (S105). This stage corresponds to the period from time t1 to t2 in FIG.

  Next, the internal pressure of the in-vehicle tank 4 is detected, and it is determined whether or not a predetermined pressure corresponding to completion of filling has been reached (S106). If the filling is not completed (S106: No), the valve opening is kept at p1 and the filling is continued (S105). When the filling is completed (S106: Yes), the flow control valve 33 and the on-off valves 24 and 31 are closed (S107). This stage corresponds to the period from time t2 to t3 in FIG. This completes the filling when the amount of residual gas in the in-vehicle tank 4 is large.

  Next, processing when the amount of residual gas in the in-vehicle tank 4 is small will be described. That is, it is a case where it is determined No in S103. In this case, if the gas is rapidly filled, the gas temperature will rise too much, which is not preferable. Therefore, the on-off valves 24 and 31 are opened, and the flow rate control valve 33 is opened to the low-speed filling valve opening (S108). This stage corresponds to the period from time 0 to t4 in FIG. In FIG. 3, the valve is opened to the low speed filling valve opening p2 at time t4. This low-speed filling valve opening p2 is a valve opening smaller than the rapid filling valve opening p1.

  The valve opening p2 is charged for a while (S109). This stage corresponds to the period from time t4 to t5 in FIG. Then, it is determined whether or not the amount of filled hydrogen gas has reached a predetermined amount (S110). This predetermined amount may be substantially the same as the determination criterion of S103, or may be adjusted in consideration of the gas temperature at that time. If the filling of the gas up to the predetermined amount is not completed (S110: No), the filling at the valve opening p2 is further continued (S109).

  Next, when it is determined that the gas has been filled up to a predetermined amount (S110: Yes), the flow rate control valve 33 is controlled to open to the rapid filling valve opening (S104). In FIG. 3, the valve is opened from the valve opening degree p2 to the valve opening degree p3 from time t5 to t6. The valve opening p3 may be the same as the valve opening p1 in FIG. The rapid filling valve opening p3 is a valve opening larger than the low-speed filling valve opening p2.

  In this state, hydrogen gas is charged into the on-vehicle tank 4 (S105). This stage corresponds to the period from time t6 to t7 in FIG. Further, the internal pressure of the in-vehicle tank 4 is detected, and it is determined whether or not a predetermined pressure corresponding to completion of filling has been reached (S106). The valve opening is kept at p3 until the filling is completed, and further filling is continued (S105). When the filling is completed (S106: Yes), the flow control valve 33 and the open / close valves 24, 31 are closed (S107). This stage corresponds to the period from time t7 to time t8 in FIG. This completes the filling when the amount of residual gas in the in-vehicle tank 4 is small. Above, description of this gas filling process is complete | finished.

  Here, it has been described that the gas filling to the in-vehicle tank 4 is performed only from the gas tank 21. However, due to the relationship between the residual gas pressure in the gas tank 21 and the gas pressure in the in-vehicle tank 4, the gas tank 21 alone may not complete the filling. In that case, the on-off valve 24 is closed and the on-off valve 26 is opened, and then the gas tank 22 is filled. This is called bank switching. Even when the bank is switched during the filling process, the valve opening degree of the flow control valve 33 may be maintained as it is.

  As described above in detail, according to the gas supply apparatus and gas supply method of the present embodiment, the amount of residual gas in the in-vehicle tank 4 is detected in advance, and when the amount of residual gas is large to some extent, it is rapidly filled. This is because if the amount of residual gas is large, the temperature rise of the gas is not so much even if it is rapidly filled, and if it is quickly filled, the filling can be completed in a short time. On the other hand, when the amount of residual gas is small, it is first charged to a predetermined amount at a low speed and then rapidly. If the amount of residual gas is small and the tank is rapidly filled, the temperature of the in-vehicle tank 4 may increase too much. Therefore, it fills at low speed until it is filled to some extent, and then fills rapidly. In this way, it is possible to fill the gas within a certain time while suppressing the maximum temperature reached by the in-vehicle tank 4. Furthermore, since the control of the valve opening degree of the flow rate control valve 33 may be performed in two or three stages, complicated control is not required and it can be easily performed.

Note that this embodiment is merely an example, and does not limit the present invention. Therefore, the present invention can naturally be improved and modified in various ways without departing from the gist thereof.
For example, in the above embodiment, the determination is made based on the amount of gas in the in-vehicle tank 4 in S103 or S110 of FIG. However, the criterion for this determination is not limited to this, and the determination can also be made based on the ratio of the residual gas amount in the tank capacity, the gas pressure in the in-vehicle tank 4, and the like.
Further, for example, the control device 36 is not limited to being provided in the dispenser 12 but may be provided in the gas storage device 11, or may be provided separately from the dispenser 12 and the gas storage device 11.
Further, for example, in the above-described embodiment, the present invention is applied to a hydrogen gas supply station that supplies hydrogen gas to a fuel cell vehicle. However, the present invention is not limited to hydrogen gas, but is applied to an apparatus that supplies other gas such as compressed natural gas. Is also applicable.
