Description

The invention relates to a gas handling unit, a so-called gas handling (GHU) for a system, in particular a vehicle, preferably a tank system of a vehicle with a fluid medium, in particular a gas, with more than 500 bar, in particular more than 700 bar, in particular in the area 700th bar to 1000 bar, to an outlet pressure of less than 50 bar, in particular less than 25 bar, in particular in the range 25 bar to 5 bar pressure.

Today, increasingly gaseous media such as natural gas or hydrogen are used as fuels for driving machines, in particular vehicles. Here, the gaseous medium, after it has been discharged from a gas station in a vehicle tank, during operation of the vehicle continuously to a consumer, such as a motor or a fuel cell, out and consumed there. This results in the problem that the tank of the vehicle when using certain fluid media, such as hydrogen, as a fuel with high pressures greater than 500 bar, in particular more than 700 bar, in particular in the range 700 bar to 1000 bar has. Hydrogen stored under high pressure in the tank is continuously fed to the consumer, e.g. B. the vehicle engine or the fuel cell discharged and under constant pressure, preferably a pressure of less than 50 bar, in particular less than 25 bar, in particular in the range 25 to 5 bar, consumed.

It is therefore necessary to provide a gas handling unit (GHU) available, which can be charged on the input side with a pressure of more than 500 bar from the tank and the output side on the consumer, eg. B. on the engine a constant pressure of less than 50 bar, in particular in the range 25 bar to 5 bar, preferably 15 bar to 9 bar, is available, it should be noted that with continuous consumption under high pressure, the pressure in the container stored fuel decreases steadily. Despite pressure decrease in the fuel tank output side should always be the same pressure on the consumer with the lowest possible pressure tolerance.

A gas handling unit (GHU) according to the prior art consists of many individual parts that are connected to each other -. For example, pipes, valves, regulators. With the number of connections in a system, the risk of failure increases according to the number of components. Also, the error analysis is more complex the more parts are installed. Thus, a functional test, a GHU according to the prior art is time-consuming and requires accurate knowledge of the blueprints and the material properties of the components used.

The object of the invention is to avoid the disadvantages of the prior art and a compact gas handling unit without the abandonment of features such. As delivery rate or pressure resistance to provide.

Furthermore, the gas handling unit (GHU) is characterized by a high reliability and a simple, compact design and provide sufficient flow.

According to the invention this object is achieved by a gas handling unit according to claim 1.

• – eine Überdruckabsicherungseinheit im Niederdruckbereich
• – eine Hochdruckmessvorrichtung
• – eine Niederdruckmessvorrichtung
• – eine Filtervorrichtung

The gas handling unit (GHU) according to the invention comprises:

• - A pressure control device
• - An overpressure protection unit in the low pressure range
• - A high pressure measuring device
• - A low pressure measuring device
• - a filter device

The GHU is at least characterized in that the pressure control device, the overpressure protection unit, the high pressure measuring device, the low pressure measuring device and the filter device form a structural unit, in particular housed in a common housing, wherein the common housing may be formed integrally or in several parts and the gas handling unit in a High pressure part (HT) and a low pressure part (NT) is divided.

In the GHU according to the invention, the system weight and the number of components is reduced, without sacrificing performance. This is achieved by integrating the components into a single component. Components of the GHU are preferably unified and standardized to form a component module. This achieves a processing simplification. If the components are integrated in a single component, the width of the component is preferably less than 100 mm, the height of the component less than 100 mm and the length of the component less than 180 mm. Preferably, the dimensions are less than 70 × 70 × 150 mm (width × height × length). A particularly preferred component has dimensions of 64 × 64 × 145 mm (width × height × length).

The gas handling unit according to the invention is thus characterized by minimal working space with simultaneous optimization of the overall component size and the weight.

Furthermore, the connection and leakage points are minimized and the number of mounting fittings.

It is particularly preferred if the pressure control device in the form of a pressure control valve at least one slide member, a piston and a spring and the pressure control unit is configured such that the input pressure is controlled by the piston via the spring and the slide member continuously to the output pressure.

Preferably, the piston is mounted floating relative to the slide member. As a result, a very quiet high control accuracy can be achieved for a mechanical, single-stage pressure regulator. Furthermore, the floating bearing allows the compensation of high shear forces, which are generated for example by the spring, which has very strong restoring forces at the wide pressure range to be controlled. The floating bearing of the piston allows the piston to oscillate and so the z. B. compensated by the spring-related transverse forces. By the oscillating piston, the wear, which is due in particular to the high, acting on the piston shear forces are greatly reduced, so that the pressure control valve according to the invention is characterized by a long life and in particular a high control accuracy, which also over the life of up to 20 years also has a slight drift in the initial pressure. The control accuracy of the pressure control valve according to the invention is ± 5 bar, in particular ± 2 bar, more preferably ± 0.5 bar for an output pressure on the output side of less than 25 bar, in particular 5 to 15 bar, preferably for example 9 bar. In the present case, control accuracy means that the outlet pressure can be maintained at, for example, 9 ± 0.5 bar, at inlet pressures of up to 900 bar. In the present case, low drift means that the initial pressure drifts only slightly over time, for example in 10 years, in particular 20 years, only by ± 1 bar, preferably ± 0.5 bar, d. H. the outlet pressure has changed in 10 years, especially 20 years, only from 9.0 bar to 9.5 bar, for example due to wear.

In order to set the restoring force in the spring and thus the output pressure on the output side, it is provided that the piston can be moved on the slider member, for example by means of a thread. In order to hold the piston in position, a locking device, which is designed to prevent rotation with locking holes into which a bolt of the floating, stored piston is designed, may be provided.

In order to adjust the pressure, it is provided that the spring of the pressure control unit has a bias and the spring acts on the piston to adjust the output pressure.

The gas handling unit according to the invention is also distinguished by the fact that the gas can flow in a flow-optimized manner from the inlet side to the outlet side. For this purpose, it is provided that the slide member comprises a bore for passing the fluid medium, in particular the gaseous medium, from the inlet side with the inlet pressure to the outlet side with the outlet pressure and / or a pointed portion, wherein the bore and / or the pointed portion preferred designed optimized flow.

Due to the high control accuracy of the pressure control valve, it is possible to form the bore with a relatively large diameter of more than 1.7 mm, in particular more than 2 mm, whereby a mass flow of more than 8 kg of fluid medium, in particular hydrogen, preferably more than 12 kg of fluid medium, in particular hydrogen, per hour at a very low inlet pressure of only 15 bar can be guaranteed. This allows for a shoring in a vehicle sufficient hydrogen supply to a fuel cell with almost empty storage tank, the low input pressures of z. B. 15 bar leads.

A particularly good tightness is achieved if, at the pointed portion of the slide member, the pressure regulating valve has a seal which comes into contact with both the pointed portion of the slider member and the housing wall. Very good tightness and high durability with good wear behavior and high temperature resistance and high resistance can be achieved if the seal in the region of the tip portion as a sealing material made of a hydrogen-resistant material, in particular polyamideimide exists. In contrast to the prior art, the seal is not applied to the tip of the slide member and seals only against metal, but is designed as a sealing ring, and the tapered sides of the tip portion of the slide member abut the sealing ring, whereby a very high tightness is achieved. Furthermore, the wear of the sealing material is low because the sealing surface is remote from the mass flow of the flowing medium, so that particles that can be in the mass flow, the seal can not destroy or attack.

The sealing ring is thus not directly in the flow of the fluid medium, and is thus wear. As a result, a long service life is achieved, which in turn leads to increased control accuracy ie low outlet pressure tolerance and to a low drift in the outlet pressure over the entire lifetime.

The sealing ring itself is in the housing of the pressure regulator, which is preferably made of aluminum, pressed.

The tightness of the pressure control valve inside, ie inside the pressure control unit, z. B. from high pressure to low pressure part is such that the leakage is less than 10 Ncm ³ / h H ₂ .

It is particularly preferred if the leakage to the inside, ie the overflow from the high pressure part in the low pressure part is less than 2 · 10 ^-4 mbar l / s H ₂ , even after 10 years, especially after 20 years.

The tightness of the pressure control valve to the outside, ie in the environment is such that the leakage is less than 10 Ncm ³ / h H ₂ is over all tight spots.

It is particularly preferred if the leakage to the outside is less than 2 · 10 ^-4 mbar l / s H ₂ , even after 10 years, especially after 20 years.

In order to prevent almost completely that particles with the gas flow on the input side get into the pressure control valve and from there, for example, in the engine, the gas treatment unit (GHU) is preferably provided with a filter device. Preferably, the filter device is designed as a fine filter on the input side in the flow direction in front of the slide member, which is preferably without limitation a filter with a mesh size in the range 2 microns to 100 microns, especially 2 microns to 40 microns, is. Such a filter is in the filed for the same applicant but post-published application PCT / EP2012 / 004692 to which reference is made in its entirety. Instead of the filter screen as described above, a sintered filter would be conceivable or a wire wound filter such as in the WO 02 / 00322A1 whose disclosure content is included in full.

In addition to the filter screen, the filter component preferably comprises a base body which forms the support body for the filter screen or filter mesh. By such a configuration, a large filter surface is provided in a small space available. Furthermore, the base body allows a multilayer structure of the filter surface, whereby an optimization of the respective required gas flow is possible. Furthermore, such a constructed filter component also has sufficient resistance to pressure peaks and alternating loads in the range 700 bar to 875 bar.

In order to be able to guide the slider component, the pressure regulating valve or the pressure regulating device has a guide bushing. The guide bush is preferably surrounded by the spring, which acts on the piston. The piston in turn preferably has seals, which are preferably arranged between the piston and the slide member and / or piston and housing wall. With such an arrangement of the pistons, it is possible that a pressureless space between the housing wall and the slider member is formed, in which the spring is arranged. Such a non-pressurized space in the region of the spring may be connected to a venting system, so that the entry of contaminants from the outside is prevented.

In the case of the gas handling unit, the high-pressure measuring device preferably comprises a high-pressure sensor in a housing bore, wherein the housing bore is connected to the high-pressure part of the pressure-regulating device in a fluid-conducting manner, preferably within the housing. Preferably, between the high pressure part of the pressure control device and the housing bore, in which the high pressure sensor is arranged, a filter, in particular a sintered filter with a mesh size of 20 microns and less, preferably 10 microns, provided so that impurities from the housing bore, such , As abrasion or particles, do not penetrate into the high pressure part of the pressure control device. The sintered filter is first preferably pressed into a bush, preferably made of PEEK, and then into the housing bore. It is particularly preferred if the high-pressure sensor is inserted in a tubular body, which in the bore by means of in the WO 2009/100898 described sealing concept for a high pressure fitting, the disclosure of which is incorporated in the present application, is introduced.

In a further developed embodiment, the low-pressure measuring device of the gas treatment unit has a low-pressure sensor in a housing bore, wherein the housing bore is fluid-conducting - preferably within the housing - connected to the low-pressure part of the pressure control device. A filter as in the case of the high pressure measuring device is not required here.

The overpressure protection unit preferably comprises a pressure relief valve which is integrated in the housing of the gas handling unit (GHU), wherein the overpressure valve preferably triggers at pressures of more than 1.5 times to 2 times a nominal output pressure. This ensures that the pressure relief valve does not trip too fast. On the other hand, it is ensured that a triggering takes place before the maximum operating pressure of the low pressure part is reached.

In order to integrate a service connection into the gas handling unit (GHU), an emptying device integrated in the housing, in particular in the form of an emptying nipple, is furthermore provided, the emptying device being connected to the low-pressure part.

In addition to the gas treatment device, the invention also provides a vehicle with a gas handling unit (GHU), the high pressure part of the gas handling unit being fluid-conductively connected to a tank system, in particular a tank container, and the low-pressure part to a consumer, in particular an internal combustion engine of the vehicle or a fuel cell.

The invention will be described below with reference to the figures.

1 shows in section AA according to 2 a gas handling unit (GHU) 1000 with a pressure control valve 1 in the present case, without limitation, in a housing component 3 is integrated. In the present case is the housing 3 without limitation, split into a first housing 3.1 and a second housing 3.2 , First and second housings are as in 2 shown connected to each other by a flange connection. The pressure control valve 1 includes a piston 5 standing on a slider component 10 is floating. The floating bearing requires that the piston can oscillate and in this way lateral forces, which are generated for example by the spring, can be compensated. Furthermore, the pressure regulating valve comprises an input side 20 , which is preferably connected to a vehicle tank (not shown). At the entrance side 20 the pressure control valve is a fluid medium, in particular a gaseous medium at a very high pressure. When hydrogen is used, as used in fuel cell vehicles, the pressure may be more than 500 bar, in particular more than 700 bar, in particular in the range 700 bar to 1000 bar. The fluid under high pressure flows through lines through the pressure regulating valve to the outlet side 30 the pressure control valve, wherein the output side of the pressure regulating valve in the region of the working machine or the fuel cell always an equal pressure of less than 25 bar, in particular for example 9 bar, is applied. The regulator is characterized in that the outlet pressure can be regulated to, for example, 9 bar to preferably 9 ± 5 bar, in particular 9 ± 2 bar, particularly preferably 9 ± 1 bar, particularly preferably 9 ± 0.5 bar.

To regulate the pressure from, for example, 875 bar down to 9 bar is a spring 40 provided so that the input pressure at the input side 20 by means of the piston 5 over the spring 40 and the slider member 10 to the outlet pressure on the outlet side 30 can be downgraded.

The output pressure acts on the outside of the piston 50 of the piston 5 because the gas from the input side 20 over the hole 60 , which is preferably designed flow optimized for a flow in the room 70 at the exit side 30 the pressure valve is passed, the outside of the piston 5 is applied and the spring 40 the necessary counterforce for pressure reduction applies. Due to the high control accuracy of the arrangement according to the invention, the bore can be relatively large, for example with a diameter of more than 1.7 mm, for example 2.0 mm. It is then possible to provide a large mass flow of fluid medium, in particular hydrogen, preferably of more than 8 kg per hour, in particular more than 12 kg per hour at 15 bar inlet pressure. Furthermore, there is a steady transition with changing cross section. Around the floating piston 5 on the slider component 10 to secure or lock, are openings 80 in slide component 10 provided in the bolt 90 passing through the piston 5 be passed through, can intervene. In this way is by means of bolts 90 The piston 5 held in a predetermined position on the slider member against rotation and set the output side pressure. The anti-rotation device prevents the piston from rotating out of the threaded position.

While the rotation of the piston 5 with the help of a bolt 90 can be done, the displacement of the piston 5 be made on the slider member, for example by means of a thread. Other embodiments for displacement of the piston are conceivable.

If several openings 80 are provided along the slide member, the piston be secured at different positions twist and so the output pressure can be set to different values. The piston 5 is both opposite the case 3 by means of a seal 7 sealed as well as a slider member by means of the seal 9 , On the front side 52 of the piston 5 on which the spring 40 acts. on the housing wall of the housing 3 becomes a space 54 trained, which is largely depressurized.

The space 54 is by means of a plug 56 locked. The plug has a membrane that allows pressure to be released from the inside to the outside when in the room 54 , z. B. due to leaks, a pressure is built up. On the other hand, the membrane prevents dirt and moisture from entering the room 54 penetrates. The guide of the slide component 10 on which the piston 5 is floating, is by means of a guide bush 100 guaranteed. By the guide tilting of the slider member is prevented and thus increases the control accuracy of the component according to the invention.

The slider component 10 is opposite the housing in front of the socket with seal 102 sealed. The seal 102 has the purpose of preventing fluid medium, in particular hydrogen, from passing the valve member into the space 54 instead of passing through the hole 60 on the back of the piston 5 ,

The high pressure part HT of the pressure regulating valve is from the low pressure part NT of the pressure regulating valve through the seal 200 separated. The seal 200 , which separates the high-pressure part HT from the low-pressure part NT, is preferably a gasket made of a hydrogen-resistant material, for example polyamideimide, polyimide or PEEK, which has very good tightness values, very good wear behavior, high durability and high temperature resistance and very high resistance.

The slider component 10 has a tip or a tip section 12 with a slant up. By the concern of the slope of the top to seal 200 a very high tightness is achieved. It is particularly preferred if a sealing inward and outward for the entire system of 2 × 10 ^-4 mbar l / s H ₂ or better is achieved, most preferably for 10 years, especially for 20 years, ie over the entire life cycle of the pressure control valve. Due to the slope, a sealing cone is formed, which comes with the seal to the plant. To derive pressure from the low pressure part NT of the pressure regulator and to be able to protect the pressure regulator from overpressure in the low pressure part NT, the gas handling unit comprises 1000 a pressure relief valve 300 , The pressure relief valve can dissipate an impermissibly high pressure in case of malfunction of the pressure regulator. The pressure relief valve according to the invention is integrated in the housing of the gas handling unit.

In order to protect the pressure control valve itself and the subsequent components from particles, is provided in the gas handling unit in the high pressure part as a filter device filter component 310 use. The filter component 310 includes, for example, a main body 312 , which is preferably conical or cylindrical and a filter network 314 that over the main body 312 is stretched with a mesh size of 2 to 100 .mu.m, in particular 2 to 40 microns.

To the tank system, to the high pressure side 20 the pressure control valve may be connected to drain for service purposes, the gas handling unit is on the low pressure side of the pressure regulator NT a drain nipple 400 , which allows easy emptying of the tank system with high external tightness. In particular, this embodiment allows that a correspondingly formed coupling can be connected leak-free under pressure. The emptying nipple can also be integrated into the housing, but it does not have to be. It would also be a separate arrangement possible.

In 2 FIG. 12 is a top view of the gas handling unit shown in FIG 1 is shown in section AA shown. The top view shows the top view of the pressure relief valve 300 as well as the emptying nipple 400 , The entrance page is with 20 marked, the output side with 30 , The section through the pressure regulating valve along the line AA according to 1 is in 2 located. Clearly visible in 2 is the division of the housing 3 a single-stage pressure control valve in two housing parts 3.1 and 3.2 shown. Both in the high pressure part HT as in the low pressure part NT, the gas handling unit 1000 Include connections for pressure sensors. In 3 , Section BB is shown a high-pressure sensor (not shown), which in a connection for a high-pressure sensor, in particular a bore 800 is housed. The hole 800 is via line 820 fluidly connected to the high pressure part, ie line 820 opens high pressure side of the seal 200 , To prevent dirt particles from drilling 800 get into the high pressure part of the pressure control valve is a sintered filter 830 shown with a mesh size of 10 microns. The Sinderfilter 830 is in a socket 840 into the hole 800 used, with which the pressure in the high pressure part can be determined.

High-pressure part HT and low-pressure part NT in the present embodiment are two components which are connected to one another via a flange 900 are tightly flanged.

In 4 is the installation of a gas treatment unit (GHU) according to the invention 1000 shown in a tank system of a vehicle. The different tank reservoirs of the tank system are with 2000.1 . 2000.2 . 2000.3 designated. The individual tanks 2000.1 . 2000.2 . 2000.3 can be refueled via a tank nipple, namely by a reservoir arranged outside the vehicle. Into the fueling string from the tank nipple 2100 over the distribution section 2200 to the respective tanks 2000.1 . 2000.2 . 2000.3 is a check valve 2300 brought in. After the vehicle was refueled through the tank nipple and the individual tanks 2000.1 . 2000.2 . 2000.3 are filled with fluid gas, especially H2, via the distributor 2200 High pressure gas to the high pressure side HT of the gas treatment unit 1000 directed. In the pipe from the tank nipple 2100 to the advantage piece 2000 is a check valve 2300 intended. Since a check valve is usually already provided in the tank nipple, the check valve is used 2300 safety. For example, if the check valve in the tank nipple leaking, so only emptied the distance between the tank nipple 2100 and the additional check valve 2300 , Would that be the extra check valve 2300 not available, the entire pipe system would be emptied. Tank nipple ensures that gaseous fluid only to the high pressure side of the gas treatment unit 1000 arrives. The gas treatment unit 1000 represents on the low pressure side NT a consumer, such as a fuel cell or an internal combustion engine 2500 fluid gas available. In the fluid path from the low pressure side NT to the consumer 2500 is the shut-off valve 2600 introduced and optionally a second pressure regulator.

The shut-off valve 2600 , which is also referred to as Sicherheitsabsperrventil, serves to be able to interrupt the flow of gas to the consumer safely, if there were in the pressure control unit increased internal leakage. The shut-off valve 2600 may in a preferred embodiment in the gas handling unit 1000 be integrated.

Although the above system is described for a vehicle, the use of a gas treatment unit is also possible in a stationary system, i. H. z. B. at a stationary fuel cell. Again, the gas treatment unit ensures that a certain pressure on the low pressure side NT for the consumer, such as the fuel cell, is constantly available.

According to the invention, a pressure sensor (not shown) is also arranged on the low-pressure side, which is in a bore 910 is used. In contrast to the hole for the low pressure sensor no filter is provided here. The bore is fluid-conductively connected to the low-pressure part.

By the high pressure sensor and the low pressure sensor, the input and the output side pressure of the pressure control valve can be constantly monitored. The sensor arranged on the low-pressure side is part of the low-pressure measuring device, which in turn is part of the gas handling unit (GHU) according to the invention. The GHU is designed so that the component has an electrical conductivity.

With the invention, a gas handling unit is first mentioned, which has a small number of components without having to accept losses in performance. This is achieved by integrating the components into a single component. The components of the GHU are preferably unified and standardized to form a component module. This achieves a processing simplification.

The gas handling unit according to the invention distinguishes minimal working space while optimizing the overall component size and the weight.

Furthermore, by the pressure control device in the form of the pressure valve, a pre-pressure of up to 875 bar single stage mechanically with a high control accuracy to 9 bar, for example 9 ± 5 bar, preferably 9 ± 2 bar, more preferably ± 1 bar, most preferably 9 ± 0.5 bar and low drift with a service life of more than 10 years, in particular more than 20 years to less than 25 bar, in particular about 9 bar, are regulated and a high flow can be provided. Furthermore, the gas handling unit is characterized by an individually changeable input adapter 1000 in 1 off, which can be adapted to the respective fuel line. The gas handling unit makes it possible to connect a tank in a vehicle, which is operated with a fluid medium under high pressure, for example a fuel cell vehicle, the tank directly to the consumer, such as the fuel cell. This makes it possible to minimize connection and leakage points, to save weight and space. The inventive oscillating and floating mounting of the piston on the slide member in the pressure control unit makes it possible to compensate for lateral forces of the spring and thus to improve the control accuracy and the wear resistance and the response. Furthermore, the spring force is adjustable, preferably before delivery of the gas handling unit.

The pressure control unit of the gas handling unit with floating piston is characterized by high low wear and very good guides and very high control accuracy and good response.
