Description

The present invention is a technique related to health promotion and the use of hydrogen gas in the medical field.

In recent years, the efficacy of hydrogen has been attracting attention in the fields of health promotion and medical treatment. In addition to hydrogen water and hydrogen baths for health promotion, hydrogen gas inhalation devices are manufactured and sold, and hydrogen gas inhalation therapy is approved as advanced medical treatment in the medical field. Regarding the production of hydrogen gas in general households and salons, in addition to a relatively simple device that mixes a hydrogen gas generator and water to generate hydrogen gas, a film of hydrogen gas obtained by electrolyzing water is further applied. A device for separating and taking out is also known.
In particular, the latter high-performance hydrogen gas generator (hereinafter referred to as "generator") can generate a large amount of hydrogen gas over a long period of time, and can be easily used for inhalation or the like when necessary. It is a very convenient device. However, many of such high-performance devices have a complicated structure and are expensive, and it is practically difficult to prepare a plurality of such high-performance devices and use them exclusively for each person, especially in ordinary households. In addition, since many devices are larger and heavier than the former easy device, poor portability is also one of the drawbacks.
On the other hand, as a substitute for a high-performance and expensive inhalation device, hydrogen gas generated by mixing water and chemicals in a small container that is easy to carry is used for inhalation, etc., which is simple and inexpensive like the former. Equipment is often used. This is highly portable and convenient, but the time it takes to generate hydrogen gas is limited, and once it is used, it is difficult to adjust the chemical reaction of the drug, and the inhalation of hydrogen gas is interrupted due to a temporary stop. There are problems such as difficulty.
For this reason, the inventor of this device has decided to use a generator and a hydrogen gas filling container (hereinafter referred to as "filling container") in order to make up for the weaknesses of both of these devices and to balance the advantages of each. There is a history of developing the pressure vessel type hydrogen gas storage device of Patent Document 1 which also has a function.

Utility Model Registration No. 3229552

The pressure vessel type hydrogen gas storage device of Patent Document 1 is a filling container that can be connected to another generator and filled with hydrogen gas generated by the device. By using this device, users without specialized knowledge and skills are not subject to legal restrictions on the handling of high-pressure gas, control the internal pressure within the specified range, and safely store hydrogen gas, which is their preference. It is a filling container (cum) suction device that can suck hydrogen gas at any time and place.
In addition, even if it is not connected to an external generator, water and a generator can be put into the inside and mixed, and the hydrogen gas generated by those chemical reactions can be inhaled or stored as it is. It is also an inhalation device.
The configuration and usage of the device of Patent Document 1 are as follows.
This pressure vessel type hydrogen gas storage device includes a pressure vessel equipped with an opening mechanism capable of charging a generator and the like, and hydrogen gas filling device, internal pressure adjusting device, and hydrogen gas discharging device, which are accessories of the pressure vessel. Has. The hydrogen gas filling device is connected to the generator in a timely manner and has a function of filling the generated hydrogen gas into the pressure vessel. The pressure vessel can be filled with hydrogen gas from the generator, and can also store the hydrogen gas generated by the generator charged inside the pressure vessel as it is. The internal pressure adjusting device functions to automatically adjust the internal pressure increased by filling the pressure vessel with hydrogen gas within a specified numerical value. The hydrogen gas discharge device includes a flow rate adjusting mechanism for discharging the hydrogen gas stored in the pressure vessel. Then, the user of this device operates the flow rate adjusting mechanism to release and stop the hydrogen gas, and further adjusts the flow rate while inhaling an inhalation mask, a nasal cannula, etc. from the tube connected to the hydrogen gas release device. Inhale hydrogen gas by means.
However, when trying to fill hydrogen gas into a filling container such as this pressure vessel type hydrogen gas storage device by using a generator that is generally on the market, the generator is used due to the pressure balance between the two. The load applied may be excessive. Therefore, it has been found that there is a risk of causing an unexpected failure in an expensive generator. Therefore, the inventor has continuously improved the convenience of the pressure vessel type hydrogen gas storage device of Patent Document 1 and continuously develops a hydrogen gas filling device that can be used for other filling containers. I have been doing research. Then, we came to the idea that there is a need for a device that enables quick and stable filling of hydrogen gas through the space between the generator and the filling container, and at the same time, can reduce the load on the generator. Is the problem to be solved by the present invention.

The hydrogen gas pressurizing and filling device of the present invention is equipped with an intake pipe, a reservoir, an upstream pressure pipe, a compressor, a downstream pressure pipe, and an exhaust pipe in this order, and produces hydrogen gas generated by a generator outside the device. , This is also a device for filling a filling container outside the device. The filling container also includes the pressure vessel type hydrogen gas storage device of Patent Document 1.
There are a plurality of piping parts in which hydrogen gas flows inside the hollow, but in the description of the present invention, they are classified into four types of parts according to their functions. One end of the intake pipe is connected to an external generator, and the other end is connected to the reservoir of the device. Each of the upstream and downstream pressure tubes is provided with a measuring means for monitoring its own internal pressure. In the following description, the applicant refers to the internal pressure measured in the upstream pressure tube as the upstream pressure, and the internal pressure in the downstream pressure tube as the downstream pressure. Further, each measuring means is referred to as an upstream pressure measuring means and a downstream pressure measuring means. Then, one end of the upstream pressure tube is connected to the reservoir and the other end is connected to the compressor. In the downstream pressure pipe, one end thereof is connected to the compressor and the other end is connected to the exhaust pipe. The other end of the exhaust pipe leading from the downstream pressure pipe is connected to an external filling container.
In addition to these, the main components of this device are the reservoir and compressor.
The reservoir is a container for gas, and an intake pipe is connected to the inflow port of hydrogen gas leading to the inside thereof, and an upstream pressure pipe is connected to an outlet connecting from the inside of the reservoir to the outside. Then, hydrogen gas can be stored in the hollow while suppressing the internal pressure of the reservoir to a predetermined value or less by an internal pressure adjusting means such as a valve mechanism or a pressure gauge. However, the inventor does not think that the role of the reservoir is to store a large amount of hydrogen gas at high pressure for a long time from the original purpose in the development of this device. In consideration of the safety of hydrogen gas, this reservoir performs storage for a short time while suppressing the internal pressure to about 0.5 MPa or less, generally 0.4 MPa or less.
The compressor has an intake port to which an upstream pressure pipe is connected to introduce hydrogen gas into the compressor, and an exhaust port to which a downstream pressure pipe is connected to discharge the pressurized hydrogen gas introduced from the intake port. It is equipped with. Further, this compressor has an internal pressure monitoring means for monitoring the value of the upstream pressure obtained from the upstream pressure measuring means of the upstream pressure tube and the value of the downstream pressure obtained from the downstream pressure measuring means of the downstream pressure tube, and the reference thereof. It operates or suspends by itself depending on the operating conditions based on the value. More specifically, it operates when the upstream pressure is equal to or higher than a predetermined value and the downstream pressure is equal to or lower than a predetermined value, and hydrogen gas in the reservoir is introduced from the upstream pressure pipe to the compressor. Pressurize and discharge to the downstream pressure tube. At the end of the exhaust pipe that continues from the downstream pressure pipe, there is a connecting means with an external filling container, and hydrogen gas is sent out and filled in the hydrogen gas filling container connected by the connecting means.
The device has the role of filling the hydrogen gas filling container with hydrogen gas more efficiently than before, reduces the excessive load on the generator, and includes the generator, this device, and the filling container. It has the role of improving the safety of the entire hydrogen gas path leading to. Therefore, in this device, it is assumed that the reference values of the upstream pressure and the downstream pressure at which the compressor starts operating are set to 0.1 MPa and 0.8 MPa, respectively, as the main operating conditions of the device. However, the inventor appropriately changes the above-mentioned numerical values set for the storage device and the compressor, for example, the downstream pressure can be variably set within the range of 0.7 MPa to 0.8 MPa. I think it's okay to consider it.
When the internal pressure of the filling container and the downstream pressure of the device exceed 0.8 MPa due to the operation of the device, the compressor is stopped to prevent an excessive increase in the internal pressure of the filling container and the device, and the generator. To prevent the occurrence of excessive load in.

The hydrogen gas pressurized filling device of the present invention further improves the ease of use of the pressure vessel type hydrogen gas storage device of Patent Document 1, and has versatility that can be used for other filling containers. Further, it has the effect of reducing the load applied to the generator and preventing the occurrence of an unexpected failure.
In addition, this device improves the efficiency of filling hydrogen gas from the generator to the filling container and completes the filling promptly, so that the connection between the generator and the filling container can be disconnected at an early stage, and their use. It improves efficiency and convenience. For example, when multiple users, such as a family member, share a single generator and inhale hydrogen gas, a high-performance generator immediately generates hydrogen gas, which is then used as a pressure vessel type hydrogen gas storage device. By efficiently filling the gas, the next user can immediately use the vacant generator. Therefore, it is not necessary for one person to exclusively use the expensive generator for a long time, and a plurality of users can share it and each person can freely inhale hydrogen gas at a convenient time and place.
In addition, since the generated hydrogen gas can be temporarily stored in a filling container and used for inhalation later, the user is not limited by the hydrogen gas supply capacity per hour provided by the generator. It is possible to efficiently obtain the required sufficient hydrogen gas.

It is a schematic diagram which shows the downstream side of this apparatus from a compressor to an exhaust pipe. It is a perspective view which shows an example of the appearance (with a housing) of this apparatus. It is a perspective view which shows an example of the appearance (without a housing) of this apparatus.

Hereinafter, the applicant will explain the hydrogen gas pressure filling device 1 according to the present invention with reference to the drawings.
FIG. 1 is an outline of this apparatus composed of a combination of main parts.
In the following description, the side where hydrogen gas is generated is referred to as upstream, and the side where hydrogen gas is discharged to the outside through this apparatus is referred to as downstream according to the direction in which hydrogen gas flows.

The hydrogen gas pressurizing and filling device 1 of the present invention has an intake pipe 2, a reservoir 3, an upstream pressure pipe 4, a compressor 5, a downstream pressure pipe 6, and an exhaust pipe 7, which are components of the device, from upstream to downstream. The devices are combined in this order. Then, as shown in FIG. 1, this device mediates the movement of hydrogen gas from the generator 9 to the filling container 10, and is used by connecting between them.
The applicant uses the names of the upstream pressure tube 4 and the downstream pressure tube 6 to include the meaning of the upstream side or the downstream side of the compressor 5 in between.
Among the parts of this apparatus, the intake pipe 2, the upstream pressure pipe 4, the downstream pressure pipe 6, and the exhaust pipe 7 are piping parts such as tubes and hoses. The intake pipe 2, the upstream pressure pipe 4, and the downstream pressure pipe 6 are connected to the reservoir 3 or the compressor 5, which mainly functions in this apparatus. The upstream side of the intake pipe 2 is connected to an external generator 9. The exhaust pipe 7 is drawn sideways in FIG. The upstream side thereof is connected to the downstream pressure pipe 6, and the downstream side is connected to the filling container 10, which serves as a path for guiding the hydrogen gas discharged from the apparatus from the downstream pressure pipe 6 to the filling container 10 further downstream.

The hydrogen gas generated by the generator 9 is introduced into the apparatus from the upstream side of the reservoir 3. The intake pipe 2 fulfills the function of the connection between the reservoir 3 and the generator 9 and the flow path of hydrogen gas between them. The downstream side of the reservoir 3 is connected to the compressor 5 through the upstream pressure tube 4. The compressor 5 is connected to the reservoir 3 via the upstream pressure pipe 4 on the upstream side thereof, and continues to the downstream pressure pipe 6 on the downstream side. Further, the downstream side of the downstream pressure pipe 6 is connected to the exhaust pipe 7, through which the present apparatus is connected to the filling container 10. Therefore, the most upstream of this device has a connecting means with the generator 9, and the most downstream of the exhaust pipe 7 is provided with a connecting means with the filling container 10. Then, the hydrogen gas flows from the generator 9 through the device and is finally filled in the filling container 10.

The hydrogen gas pressurizing and filling device 1 in FIG. 1 integrates the intake pipe 2, the reservoir 3, the upstream pressure pipe 4, the compressor 5, the downstream pressure pipe 6, and the exhaust pipe 7 to facilitate the handling of the device. It is housed in a housing 8 that protects the main part of the. However, the inventor does not need the housing 8 due to the specifications of this device, and pressurizes hydrogen gas by combining only the intake pipe 2, the reservoir 3, the upstream pressure pipe 4, the compressor 5, the downstream pressure pipe 6, and the exhaust pipe 7. It is considered that the filling device 1 may be used. For example, instead of the housing 8, the user may easily organize each component with something like a rack.
In the specification including the housing 8, the connecting means of the present device and the generating device 9 and the connecting means of the present device and the filling container 10 are installed on the outer surface of the housing 8, respectively, and the user can use general-purpose piping parts. May be used to connect this device to an external generator 9 or a filling container 10.

Next, the applicant will explain in detail the structure of each component and their combinations in order from the upstream side to the downstream side of the hydrogen gas pressure filling device 1. However, they show an example of the hydrogen gas pressure filling device 1 according to the present invention.

FIG. 2 illustrates the side of the reservoir 3 upstream of the compressor 5.
One end on the upstream side of the intake pipe 2 is provided with a connecting means for connecting to the generator 9 or a general-purpose connecting pipe connected to the generator 9. The other end on the downstream side of the intake pipe 2 is connected to the reservoir 3, and the hydrogen gas generated by the generator 9 is sealed in the intake pipe 2 having airtightness except for both ends. It flows to 3. The intake pipe 2 is often made of a material such as metal or plastic from the viewpoint of strength and prevention of hydrogen gas leakage, and an elongated hollow structure pipe, tube, hose or the like is often used from the viewpoint of pipe management.

The means for connecting the intake pipe 2 to the generator 9 may be a specification for directly connecting the intake pipe 2 and the generator 9, but as described above, a general-purpose method is used between the intake pipe 2 and the generator 9. Specifications that interpose a connecting tube, for example, these may be indirectly connected by an extension vinyl tube or the like. That is, as the connecting means on the upstream side of the intake pipe 2, it is also possible to adopt a means for facilitating connection and disconnection with such a general-purpose connecting pipe.
On the other hand, the other end of the intake pipe 2 is connected to the reservoir 3. The connection on the downstream side may be a fixed connection, or may be a detachable connection as in FIG. 2 with respect to the upstream side. As an example of these connecting means, it is easy to adopt a coupler which is a joint used for a fluid piping component or the like and enables quick connection and disconnection.

In this way, the intake pipe 2 connects the reservoir 3 of the present device and the external generator 9. At this time, it is possible to freely connect and disconnect not only the generator 9 side but also the reservoir 3 side on the downstream side as shown in FIG. 2, for example, the present device such as replacement or expansion of the reservoir 3. This will improve the convenience of this device during maintenance and improvement of the device.
Further, it is also effective to appropriately provide a valve, a changeover switch, or the like in the middle of the intake pipe 2 to prevent the backflow of hydrogen gas. Further, it is also meaningful to install a mist separator or a water separator in the intake pipe 2 in order to separate the water contained at the time of generation and dry the hydrogen gas to prevent the water from entering the reservoir 3.

The reservoir 3 is a temporary storage container for gas. In order to withstand the rise in internal pressure, it may be shaped like a cylinder or tank and made of light metal in consideration of strength and weight. However, there is no reason why the material of the reservoir 3 should not necessarily be limited to this.
Further, there are no particular restrictions on the capacity thereof, and there is no problem in using the present device from the viewpoint of portability and the like, and a reservoir 3 having a size in consideration of safety may be appropriately selected. Therefore, in addition to the case where the storage device 3 is a single cylinder or the like, a storage device 3 in which a plurality of them are combined may be used, and these may be used as a removable storage device 3 and added as necessary. It is also expected that the specifications will be possible.

Then, the intake pipe 2 is connected to the inflow port of the hydrogen gas on the upstream side in the reservoir 3, and the upstream pressure pipe 4 is connected to the outflow port of the hydrogen gas on the downstream side. Regarding the connection between the reservoir 3 and the upstream pressure pipe 4, similarly to the connection between the intake pipe 2 and the reservoir 3 in FIG. 2, these are detachably connected by a connecting means such as a coupler to form the present device. Is also possible.
From such a configuration on the upstream side of the present device, the hydrogen gas generated by the generator 9 is sequentially introduced into the inside of the reservoir 3 through the intake pipe 2 and temporarily stored in the reservoir 3. , Moves downstream through the upstream pressure tube 4.

At this time, according to the general specifications of this device, the hydrogen gas generated by the generator 9 is discharged to the device side at a supply pressure of about 0.2 MPa to 0.8 MPa, ideally 0.4 MPa or more. Is assumed. The hydrogen gas discharged from the generator 9 in this way flows into the reservoir 3, and its internal pressure gradually rises. On the other hand, the reservoir 3 is provided with an internal pressure adjusting means such as a pressure gauge and a safety valve for monitoring and suppressing the internal pressure, and the hydrogen gas flowing into the reservoir 3 from the intake pipe 2 is approximately 0.1 MPa. It is stored in a safe state where the pressure is kept low within the range from to 0.4 MPa.
Further, in addition to the internal pressure adjusting means, the inlet and the outlet are brought close to each other and aggregated in the reservoir 3 as shown in FIG. 2, and the inflow of hydrogen gas from the intake pipe 2 and the inflow of hydrogen gas are performed. It is also conceivable to have a mechanism in which the outflow to the upstream pressure tube 4 is automatically switched according to the situation.

The upstream end of the upstream pressure pipe 4 is connected to the outlet of the reservoir 3, and the other end of the upstream side is connected to the intake port of the compressor 5. Since the upstream pressure tube 4 pressurizes the hydrogen gas by the compressor 5, it functions as a path for introducing the hydrogen gas temporarily stored in the reservoir 3 into the compressor 5. The same upstream pressure tube 4 also serves as a pressure measuring tube for measuring the upstream pressure, which is one of the criteria for determining the operation or suspension of the compressor 5.
Since the upstream pressure pipe 4 is a piping component, it often has a hollow and elongated shape like the intake pipe 2. However, it is also possible to integrate these as a component in which the intake pipe 2 and the upstream pressure pipe 4 are integrally combined. For example, the intake pipe 2 and the upstream pressure pipe 4 are integrated via a member in which the pressure gauge shown in the upper part of the reservoir 3 in FIG. 2 is arranged. Such a combinational component is connected to the inlet and outlet of the reservoir 3 by a connecting means, and is automatically connected to the inlet on the intake pipe 2 side and the outlet on the upstream pressure pipe 4 side by the function of a switch or a valve. The valve is opened and closed to switch the flow of hydrogen gas as appropriate.

The hydrogen gas flowing from the reservoir 3 to the upstream pressure tube 4 on the downstream side raises the internal pressure of the upstream pressure tube 4 which is a measuring tube. The numerical value of the internal pressure measured as the upstream pressure in the upstream pressure pipe 4 is acquired by an upstream pressure measuring means such as a pressure gauge or a sensor installed in the upstream pressure pipe 4, and the fluctuation state is monitored by the compressor 5.
A similar downstream pressure measuring means is also installed in the downstream pressure pipe 6 on the downstream side of the compressor 5, measures the downstream pressure as a numerical value indicating the internal pressure thereof, and monitors the fluctuation of the numerical value in the compressor 5. Will be done.

FIG. 3 illustrates the downstream side from the compressor 5.
The compressor 5 is a device that sucks hydrogen gas temporarily stored in the reservoir 3 into its own interior, pressurizes it, and exhausts it to the downstream side according to the fluctuation state of the internal pressure in the upstream and downstream thereof. be. In order to maintain the function of this device, a pressure reducing valve or the like that functions as an air regulator is installed in the upstream pressure tube 4 or the compressor 5 as needed.
The compressor 5 monitors the values of the upstream pressure and the downstream pressure measured by the measuring means provided in the so-called upstream upstream pressure pipe 4 and the downstream downstream pressure pipe 6 by the internal pressure monitoring means linked to these measuring means. , Operates by itself based on the prescribed operating conditions, or suspends by itself.
After the generator 9 and the present device are started, the upstream pressure becomes equal to or higher than the predetermined pressure, so that the pressurization preparation on the upstream side of the present device is ready. In addition, when the downstream pressure is equal to or lower than the predetermined pressure, the filling preparation on the downstream side of the filling container 10 side is ready.
Then, under such operating conditions, the compressor 5 operates, and the hydrogen gas in the reservoir 3 is introduced into itself from the upstream pressure pipe 4 connected to the intake port, and this is pressurized to the downstream connected to the exhaust port. It is sent out to the pressure tube 6.

The purpose of this device is to suppress the pressure rise of hydrogen gas within a predetermined range in the device itself, the generator 9 on the upstream side of the device, and the filling container 10 on the downstream side. The purpose is to enable the safe use of hydrogen gas at homes and salons. Therefore, it is originally assumed that both the upstream pressure and the downstream pressure are set as operating conditions lower than the pressure subject to regulation as high pressure gas, and the maximum pressure of hydrogen gas handled by this device is 1 MPa or more. It has not been.
Then, for example, when the upstream pressure on the reservoir 3 or the upstream pressure tube 4 side is 0.1 MPa or more, and the downstream pressure of the hydrogen gas sent from the compressor 5 to the downstream pressure tube 6 is 0.8 MPa or less. The compressor 5 starts operation. Therefore, even when the hydrogen gas temporarily stored in the reservoir 3 is pressurized by the compressor 5 and filled in the filling container 10, the internal pressure exceeds 0.8 MPa, and further, the safety margin is greatly exceeded. It is used for inhalation and the like in a very safe state without the risk of overfilling by 1 MPa or more.

The downstream pressure pipe 6 is a part of the flow path of hydrogen gas whose upstream side is connected to the discharge port of the compressor 5, the downstream side is connected to the exhaust pipe 7, and is pressurized by the compressor 5 and discharged to the outside of the apparatus. become. The downstream pressure tube 6 serves as a measuring tube for monitoring the downstream pressure, which is the second reference value when determining the operation of the compressor 5.
Since it is a piping component like the intake pipe 2, the upstream pressure pipe 4, and the exhaust pipe 7, it is often hollow and elongated like them. Further, in consideration of convenience during maintenance and use, the connecting means to the compressor 5 and the exhaust pipe 7 may be of a detachable specification using a coupler or the like as shown in FIG.
In this way, the downstream pressure measuring means installed in the downstream pressure pipe 6 monitors the internal pressure even on the downstream side of the present apparatus, and automatically controls the operation and deactivation of the compressor 5. Therefore, adjustments are made so that an excessive pressure rise does not occur not only on the upstream side of the reservoir 3 and the upstream pressure pipe 4 but also on the downstream side of the present device including the filling container 10.

The exhaust pipe 7 is a pipe that extends further downstream from the downstream pressure pipe 6 and is connected to the filling container 10 side, and is detachably connected to the filling container 10 so as not to be inadvertently disconnected. There is a need. Then, the hydrogen gas pressurized by the compressor 5 is filled in the filling container 10 through the exhaust pipe 7.
At this time, a mist separator may be installed in the exhaust pipe 7 to keep the inside of the filling container 10 dry, or an air duster gun type connecting means for facilitating the filling work may be adopted. Conceivable. The latter is a kind of connection means in which a coupler or the like is installed in a pistol-shaped instrument, and hydrogen gas pressurized by a compressor 5 is injected into a filling container 10 appropriately connected to the coupler or the like.
The intake pipe 2 and the upstream pressure pipe 4 sandwich the reservoir 3 from the upstream and the downstream, whereas the downstream pressure pipe 6 and the exhaust pipe 7 are in a series on the downstream side of the compressor 5. It is also easy to make a continuation of parts. Therefore, it is considered that the number of present devices using such parts as the downstream pressure pipe 6 (cum) exhaust pipe 7 will increase.

FIG. 4 illustrates an example of the appearance of the hydrogen gas pressure filling device 1 of FIG.
This is a state in which the main part of the present device is completely housed in the housing 8. Therefore, FIG. 4 is shown as a state in which the inside thereof cannot be visually recognized.
Although the housing 8 is a case made of metal, plastic, or the like, it is adopted as necessary in order to protect the main parts of the present apparatus together and to improve portability and operability. On the outer surface, there is a switch for starting this device, a pressure gauge for visually checking the internal pressure of the reservoir 3, and a flow path for hydrogen gas connected to an external generator 9 and a filling container 10. A means of connecting to a part of general-purpose piping parts, etc. is installed as needed.

FIG. 5 is an example of a hydrogen gas pressure filling device 1 having specifications that are not stored in the housing 8.
The device of this example is illustrated in a rack that facilitates the transport of the reservoir 3 and the compressor 5. Further, on the central upper surface of the compressor 5, in addition to the switch and the pressure gauge, a connecting means for connecting the generator 9 and the filling container 10 is provided. However, the details of the piping members including the intake pipe 2 are omitted and not shown in this figure.

At the end of the description, the applicant will explain the basic usage of this device.
Commercially available generators 9 include high-performance models capable of continuously and efficiently generating a large amount of hydrogen gas by electrolysis of water or the like. This device is connected to such an external generator 9 and a filling container 10, mediates between them, and fills the hydrogen gas continuously generated by the generator 9 while applying an appropriate pressure. Fill the container 10. Therefore, this device is connected to the generator 9 and the filling container 10 each time it is needed.
However, the main purpose of this device is to enable the easy and safe use of hydrogen gas at homes and salons. Therefore, the inventor does not intend to handle or store hydrogen as a high-pressure gas in the use of this device, including the generator 9 on the upstream side and the filling container 10 on the downstream side. Therefore, it is assumed that the upper limit of the internal pressure allowed in this device is generally within the range of 0.7 MPa to 0.8 MPa, and even if this is the maximum, it will be 1.0 MPa or more. Not done.

The user of this device connects the intake pipe 2 and the exhaust pipe 7 of this device to the generator 9 and the filling container 10, and then operates and starts the generator 9 to generate hydrogen gas. Is started. Next, the user turns on the power of the compressor 5. In FIG. 4, it is installed in front of the housing 8, and in FIG. 5, a switch installed on the central upper surface of the compressor 5 is operated to start the apparatus.
The hydrogen gas generation capacity of the generator 9 is preferably a device capable of generating hydrogen gas at a supply pressure of 0.4 MPa or more, but the generator has a capacity of approximately 0.2 MPa to 0.8 MPa. If it is 9, the device can be used. Therefore, it is expected that many generators 9 that are manufactured and sold as devices having a general hydrogen gas generation capacity and are widely used in society will be used.
On the other hand, even when the hydrogen gas generation capacity is lower than this and the supply pressure generator 9 does not reach 0.4 MPa as an example of the recommended pressure, this device can be used. However, the time until the downstream pressure of 0.8 MPa, which is assumed as the reference for the compressor 5 to stop, is reached, that is, from the start of this device to the completion of hydrogen gas filling into the filling container 10. It will take time.
Further, by making it possible to change the internal pressure of the reservoir 3 and the numerical values of the operating conditions of the compressor 5, the present apparatus can easily correspond to a wider variety of generators 9.

In the generator 9 connected to the present device by the connecting means of the intake pipe 2, a large amount of hydrogen gas is generated by electrolysis of water or the like. The continuously generated hydrogen gas passes through the intake pipe 2, flows in from the inlet of the reservoir 3, and is stored inside the intake pipe 2.
The internal pressure of the reservoir 3 in this device is maintained by a regulating valve or the like within a relatively low numerical range of around 0.4 MPa, up to 0.5 MPa at the maximum, in order to avoid high-pressure storage of flammable hydrogen gas. Will be done.

The upstream pressure pipe 4 having one end on the upstream side connected to the outlet of the reservoir 3 is connected to the intake port of the compressor 5 at the other end on the downstream side, and an upstream pressure as an internal pressure is generated inside the upstream pressure pipe 4. There is. On the other hand, a downstream pressure pipe 6 is connected to an exhaust port on the downstream side of the compressor 5. Further, the downstream pressure pipe 6 is connected to the exhaust pipe 7, is connected to the external filling container 10 by the connecting means of the exhaust pipe 7, and a downstream pressure as an internal pressure is generated inside the downstream pressure pipe 6.
Then, the values of the upstream pressure and the downstream pressure are measured by the upstream pressure measuring means and the downstream pressure measuring means installed in each of the upstream pressure pipe 4 and the downstream pressure pipe 6 and connected to the compressor 5, and the compressor linked with these measuring means. The internal pressure monitoring means of No. 5 is in a state where both the fluctuations of the upstream pressure and the downstream pressure can be monitored.

The compressor 5 has, for example, operating conditions in which the upstream pressure on the upstream side obtained from the upstream pressure measuring means is 0.1 MPa or more, and the downstream pressure on the downstream side obtained by the downstream pressure measuring means is 0.8 MPa or less. Inhale, pressurize, and discharge hydrogen gas below.
By the way, in order to avoid high-pressure storage of hydrogen gas, the pressure vessel type filling container of Patent Document 1 adjusts the internal pressure of hydrogen gas within a range such as 0.7 MPa or 0.8 MPa in consideration of a safety margin. It was a device that tried to suppress the pressure. Similarly, this device aims to suppress the internal pressure and use hydrogen gas safely, and the internal pressure of the filling container 10 is in the same range of 0.7 MPa to 0.8 MPa or in the vicinity thereof. It is supposed to be the numerical value of.

Hydrogen gas is sent from the generator 9, the internal pressure of the reservoir 3 increases, and when the upstream pressure measured by the upstream pressure tube 4 reaches 0.1 MPa, the compressor 5 operates and temporarily enters the reservoir 3. The stored hydrogen gas flows to the downstream compressor 5 side. Further, the hydrogen gas sucked by the compressor 5 and pressurized is discharged to the filling container 10 through the downstream pressure pipe 6 and the exhaust pipe 7.
Similar to the pressure vessel type hydrogen gas storage device of Patent Document 1, this device maintains the internal pressure of the other filling container 10 by suppressing it to about 0.8 MPa at the maximum from the viewpoint of safety. It is something that makes you. Then, when the downstream pressure on the downstream side increases to 0.8 MPa due to the hydrogen gas sent out from the compressor 5 and the internal pressure of the filling container 10 becomes equal to this, the compressor 5 automatically stops. .. Therefore, the flow of hydrogen gas toward the downstream pressure pipe 6, the exhaust pipe 7, and the filling container 10 on the downstream side is stopped.

After the filling of the filling container 10 with hydrogen gas is completed, the user turns off the switch of the apparatus and the generator 9 to stop both, and disconnects the generator 9 and the filling container 10 from the apparatus. , Separate these. Then, the pressure vessel type hydrogen gas storage device and the filling container 10 can be freely carried, and can be inhaled according to one's taste and need without being restricted by the place and time, or can be used as a hydrogen bath in the bathroom. It becomes possible to freely use hydrogen gas, such as by providing it.
On the other hand, the next user can also fill the filling container 10 with hydrogen gas by using the generator 9 and the present device, which have been used up earlier, and can freely use the hydrogen gas including inhalation.
Further, the inventor considers that it is very meaningful not only to use the present device having the specifications described so far, but also to use the generator 9 in which the present device is incorporated in advance.
