Definitions
- the invention relates to a device for the permanent supply of a consumer with gas, with a first extraction line connected to a first compressed gas reservoir and a second extraction line connected to a second compressed gas reservoir, which open into a common delivery line, and with one equipped with pressure measuring devices and shut-off devices in the extraction lines Switching device which is set up so that when the pressure value at the shut-off device in the first extraction line falls below a predetermined inflow-side pressure value, the shut-off device closes and the shut-off device in the second extraction line opens.
- Pressurized gas cylinders should be understood here as pressurized gas storage tanks with a filling volume between 101 and 2001 with a filling pressure between 150 bar and 300 bar, in which a gas, for example nitrogen, oxygen, carbon dioxide, a noble gas or a gas mixture, in particular a welding gas mixture or a for Food applications specific gas mixture that is stored under pressure in a gaseous state.
- a gas for example nitrogen, oxygen, carbon dioxide, a noble gas or a gas mixture, in particular a welding gas mixture or a for Food applications specific gas mixture that is stored under pressure in a gaseous state.
- a “compressed gas cylinder bundle”, hereinafter also referred to as a “cylinder bundle”, is to be understood as an arrangement in which a number, for example four to twelve, compressed gas cylinders with a filling volume of between 50I and 200I with a filling pressure between 150 bar and 300 bar in one built up from frame elements, mostly open or partially open, transportable by a forklift frame are installed and connected to a common extraction line.
- Pressurized gas cylinders, cylinder bundles and groups of coupled pressurized gas cylinders or cylinder bundles are also summarized below under the term "pressurized gas storage”.
- pressurized gas accumulators of the type mentioned the problem arises that the amount of gas available is limited, with the result that an operator is in front of it, particularly in the case of pressurized gas accumulators from which gas has already been taken At the beginning of an activity, it is always necessary to check whether the amount of gas available is sufficient for the intended task. If necessary, a pressurized gas container that still has a considerable amount of residual filling must be exchanged for a full pressurized gas container, which incurs costs.
- Such a battery consists, for example, of two bundles of bottles or two groups of bundles of bottles that are coupled to one another, each of which is equipped with an extraction line, the extraction lines of the two bundles of bottles (or of the two groups of bundles of bottles) opening into a common delivery line at a connection point.
- a switching device is provided upstream or at the connection point - this is usually designed as two shut-off devices or as a three- or four-way valve - which is used to switch from one extraction line to the other extraction line.
- the switching device switches to the second extraction line and thus to the second bundle of cylinders.
- the residual or pre-pressure of the emptied discharge side or the desired supply pressure can be used as the determining switchover parameter.
- the switchover can be done manually or automatically.
- the supply then takes place from the second bundle of bottles, while the first bundle of bottles can be decoupled from the system and exchanged for a full bundle of bottles.
- a permanent gas supply is possible by alternately exchanging the two bundles of cylinders for full bundles of cylinders.
- Bottle batteries of the aforementioned type are known, for example, from DE 1 501 703 A1 or DE 102006002271 A1.
- DE 1960448 A describes a similar arrangement of two gas cylinders, particularly suitable for camping purposes, each equipped with pressure regulators that are set to different withdrawal pressures.
- the technology of bottle batteries has seen constant improvement over time.
- non-return gas valves as described for example in DE 102007051 927 A1, it is possible to prevent gas from penetrating from the pressurized gas store at a higher pressure into the pressurized gas store at a lower pressure.
- the invention is therefore based on the object of creating a gas supply system which allows a permanent gas supply and which overcomes the disadvantages of the prior art.
- the switchover device is set up in such a way that, when there is a pressure value on the upstream side of the shut-off device in the first extraction line, which is above the upstream pressure at the shut-off device in the second extraction line is, a flow connection to the second pressurized gas storage is established.
- the device according to the invention thus has two extraction lines to each of which a pressurized gas reservoir can be connected.
- the switching device comprises shut-off devices in both extraction lines and pressure measuring devices installed at least on the upstream side in front of the shut-off devices, as well as a control by means of which the shut-off devices are automatically actuated depending on the pressures measured in the extraction lines. If both pressurized gas containers are connected and filled, only the shut-off device in the first extraction line is open - in a manner known per se - and gas is extracted only from the first pressurized gas reservoir.
- the shut-off device in the first extraction line preferably closes automatically and the shut-off device in the second extraction line opens; the gas supply now takes place exclusively from the second pressurized gas store and the first pressurized gas store can now be separated from the first extraction line and exchanged for a full pressurized gas store.
- the upstream pressure at the shut-off device in the first extraction line exceeds the upstream pressure at the shut-off device in the second extraction line.
- the “inflow side” is to be understood here as the side on the shut-off valve which is opposite the opening of the corresponding extraction line into the common discharge line. Due to the device according to the invention of the switching device, a flow connection is now established from the first to the second pressurized gas reservoir. This takes place, for example, in that the shut-off device in the first extraction line and the shut-off device in the second extraction line open simultaneously.
- the second pressurized gas store is now filled from the first pressurized gas store by overflowing it until a pressure equalization between the pressurized gas stores or at least a predetermined pressure value is reached in the second pressurized gas store.
- the shut-off device in the second extraction line is then closed and only opened when the pressure value in the first compressed gas reservoir falls below the specified pressure value again in the course of supplying the consumer.
- the common delivery line is preferably open, i.e. there is a permanent supply of gas to the consumer.
- the second compressed gas reservoir it is therefore not necessary to separate the second compressed gas reservoir from the second extraction line after use and to replace it with a full compressed gas reservoir. Only the first pressurized gas reservoir needs to be replaced for permanent supply to the consumer; the second Pressurized gas storage remains at the customer's location. This reduces the effort involved in monitoring and logistics.
- a gas non-return valve can be provided which prevents an undesired passage of gas from the filled compressed gas reservoir into the emptied compressed gas reservoir.
- a gas return valve can also be installed in the second extraction line, for example in the event that the second compressed gas reservoir is only refilled to a filling pressure which is lower than the maximum filling pressure in the first compressed gas reservoir.
- the shut-off device in the second extraction line comprises a separate line (bypass line), which enables the filling of the second pressurized gas reservoir and which is equipped with a control valve that ensures an even and not too violent filling process.
- This bypass line is closed by means of a valve as soon as the filling process has ended and / or it is in turn equipped with a non-return valve that prevents gas from flowing back after the filling process has ended.
- the switching device is preferably set up in such a way that the flow connection from the first to the second pressurized gas storage tank closes when the upstream pressure at the shut-off device in the second extraction line exceeds a predetermined value that is selected so that the amount of gas present in the second pressurized gas storage tank is sufficient to Ensure supply of the consumer for a certain time, for example between 15 min and 120 min.
- the flow connection to the second pressurized gas reservoir should be closed when there is at least approximately a pressure equalization between the two pressurized gas reservoirs, measured by the upstream pressure at the shut-off device in the first extraction line and the upstream pressure at the shut-off device in the second extraction line.
- a container or a plurality of containers is expediently provided as the first pressurized gas reservoir, which containers are easy to transport and easy to replace.
- this is a pressurized gas cylinder, a bundle of cylinders or a plurality of pressurized gas cylinders or bundles of cylinders.
- the volume of the second compressed gas reservoir can be selected to be much smaller than that of the first compressed gas reservoir.
- the second pressurized gas reservoir has at most one tenth, preferably at most one twentieth, of the volume of the first pressurized gas reservoir.
- the second pressurized gas reservoir functioning as a buffer tank is preferably a pressurized gas cylinder or a comparable pressure vessel with a volume of, for example, between 101 and 501.
- the second pressurized gas store expediently remains permanently, that is, during and after an exchange of the first pressurized gas store on site and with the second extraction line connected.
- FIG. 1 shows schematically the structure of a device according to the invention.
- the device 1 comprises, as a first pressurized gas storage device, a cylinder bundle 2 of, for example, six, eight, nine, twelve, sixteen or eighteen pressurized gas cylinders 3, which is accommodated within a frame 4.
- the bottles 3 are connected to a removal line 8 by means of pipe or hose connections 6 via a connection distributor 7.
- the frame 4 is preferably an open welded construction made of steel profiles and comprises in a conventional manner a floor 9 and a transport section 10 arranged below the floor, which is intended in particular for the engagement of forklift forks.
- the removal line 8 extending transversely through the frame 4 is equipped with a connecting piece 11, for example a flange or a thread, on which the bundle of bottles 2 can be separated from the rest of the device 1 in a simple manner.
- a locking valve 12 is arranged in the extraction line 8. In a manner not shown here, more can also be added to the extraction line 8 Be connected to the cylinder bundle, which together with the cylinder bundle 2 form the first pressurized gas storage device within the meaning of the present invention.
- the device 1 has a conventional compressed gas cylinder 14 as the second compressed gas storage device.
- the pressurized gas cylinder 14 is equipped with a withdrawal valve 15 to which a withdrawal line 16 is connected.
- the extraction lines 8, 16 open into a common discharge line 17, which establishes a flow connection with a consumer 18.
- the device 1 has a switchover device 20 which, in addition to a control unit 19, which, moreover, can also be implemented in a remote control center, has several shut-off devices 21, 22, 23 and pressure measuring devices 24, 25, such as manometers, in the delivery line 17 (Shut-off device 21), in the extraction line 8 (shut-off device 22 and pressure measuring device 24) and in the extraction line 16 (shut-off device 23 and pressure measuring device 25).
- the switching device 20 can include further devices, not shown here, such as sensors, transmitters, etc., with which further physical or chemical parameters, such as the ambient temperature, are taken into account in the control unit 19, or wireless information transmission to or from the control unit 19 can be produced.
- the withdrawal of gas from the compressed gas reservoirs 2, 14 is automatically regulated in the manner described below as a function of pressures that are measured at the pressure measuring devices 24, 25.
- the shut-off device 22 is opened and the shut-off device 23 is closed.
- the consumer 18 is supplied with gas from the cylinder bundle 2, a pressure holding device 26 ensuring that a predetermined pressure is maintained in the delivery line 17.
- the pressure measured at the pressure measuring device 24 in the cylinder bundle 2 falls below a predetermined value, for example a minimum pressure required to supply the consumer 18. If the pressure in the bundle of bottles 2 falls below this value, the shut-off device 22 is closed and the shut-off device 23 is opened.
- the consumer 18 is now supplied from the compressed gas cylinder 14.
- shut-off valve 12 is closed, the bundle of cylinders 2 at the connecting piece 11 is decoupled from the rest of the device 1, and instead a full bundle of bottles is connected to the connecting piece 11.
- the pressure on the pressure measuring device 24 is now greater than the pressure on the pressure measuring device 25, which at the same time corresponds to the pressure in the compressed gas cylinder 14.
- shut-off device 22 is now opened, the shut-off device 23 remains open (or a flow connection opens via a bypass line not shown here) and the gas flows from the exchanged cylinder bundle 2 both to the consumer 18 and into the pressurized gas cylinder 14.
- the shut-off device 23 is closed and the gas again flows exclusively from the cylinder bundle 2 to the consumer 18.
