Description

The method that oxygen reduces system and reduces system for operating oxygen
System is reduced the present invention relates to oxygen and the method for operating this system.
Such oxygen according to the present invention reduces system and is used in particular in the air for controllably reducing closed area Oxygen content.For this purpose, it includes the admixture of gas or indifferent gas for providing oxygen reduction respectively that oxygen, which reduces system, The gas separation system of body and the pipe-line system that fluidly connects or can fluidly connect with gas separation system and closed area, At least part of the admixture of gas provided by gas separation system or gas to be supplied to closed area as needed.
According to the method for the present invention or corresponding system is for example for reducing the fire risk in protected room to be monitored And stamp out a fire, it thus in order to prevent or stamps out a fire, closed room can also or can be constantly to different relatively low water It is flat that inertia is presented.
Basic principle for fireproof inerting techniques be based on such a understanding, i.e., only by human or animal once in a while It, can be by by phase in the closed room of entrance, and comprising being exposed to the equipment sensitively to react when water in closed room Answer the oxygen concentration in region that the value of such as about 15 volume % is reduced to cut down fire risk.In this (reduction) oxygen Under concentration, most of combustible materials cannot refire.Therefore, this main application fields for fireproof inerting techniques It is the storage region of the regions EDP, electric switch and switchgear house, closed installation and the economic goods with special high value.
The flameproof effect that this method generates is the principle based on replacement of oxygen.Known normal environment air is by 21 volume % Oxygen, other gases composition of the nitrogen of 78 volume % and 1 volume %.For purpose of preventing fires, by introduce such as nitrogen it Oxygen content in room atmosphere of the drive carrier of oxygen of class to reduce closed room.Oxygen content one is less than normal environment air Oxygen content, flameproof effect are begun to.According to the combustible in protected room, it may be necessary to further drop oxygen content As low as such as 12 volume %.
It is that oxygen content has subtracted wherein that oxygen according to the present invention, which reduces system or another application example of method, Hypoxic training condition is provided in few closed room.Such room can instruct under the high altitude condition of manual simulation Practice, also referred to as " normal pressure low oxygen training ".
Further application example is that article, especially food are stored in so-called " controlled atmosphere (CA) ", preferably Pomaceous fruit, in addition, wherein adjusting the proportionality percentage of aerial oxygen to slow down the ageing process for acting on perishable commodity.
The oxygen of the above-mentioned type reduces well known in the art on system principle.For example, printed publication DE19811851A1 describes a kind of inert system, is designed to the oxygen content in closed room being reduced to specifically Substantially inertization is horizontal, and event of fire, and oxygen content is further reduced rapidly to specific completely inertization water It is flat.
Term " substantially inertization is horizontal " used herein is interpreted as subtracting compared with the oxygen content of normal environment air Few oxygen content, although the oxygen content of this reduction will not cause danger to human or animal so that they still can be into Enter and-at least briefly-enters permanent deactivation region without any problem；That is not special safety precaution, such as Oxygen mask.Basic oxygen content of the inerting level for example corresponding to 15-17 volumes % in closed area.
On the other hand, term " completely inertization horizontal " be interpreted as compared with the oxygen content of substantially inertization level into The oxygen content that one step reduces, the combustibility of wherein most material have already decreased to the degree that they cannot be refired.Depend on In the fire load in relevant range, the horizontal common oxygen concentration of completely inertization is about 12-14% volumes.
System is reduced in order to be equipped with oxygen to closed area, it is necessary first to corresponding inert gas source is provided, so as to Admixture of gas or inert gas that oxygen in closed room to be introduced reduces are provided respectively.The output energy of inert gas source Power, i.e., the amount for the inert gas that can be provided per unit time by inert gas source, is consequently adapted to the property of closed area, especially The spatial volume and/or air-tightness of closed area.
If reducing system using oxygen is used as (preventative) fire control measure, event of fire should be especially ensured The inert gas of sufficient amount can be introduced into the room atmosphere of closed area in the shortest time so that extinguishing effect is as far as possible Start soon.
Although admixture of gas/inert gas that the oxygen for being introduced as needed within closed area reduces can be stored in one group Gas cylinder or similar compressed gas reservoir in, but by inert gas source provide oxygen reduce admixture of gas At least part of " produced on-site " received, especially because inert gas is stored in one group of gas cylinder or similar pressure Special structural measure is needed in contracting gas reservoir.
The admixture of gas of the oxygen reduction provided by inert gas source in order to live " production " or inert gas At least partially, inert gas source generally includes the gas in addition to one group of gas cylinder or similar compressed gas reservoir point From system, go out wherein being fed at least part oxygen separation contained in the initial gas mixture of gas separation system Come, to provide the admixture of gas that oxygen reduces in the exit of gas separation system.
Term " initial gas mixture " used herein is it is generally understood that for the gas mixing other than oxygen components Object, the admixture of gas especially also contain nitrogen, and also contain the gas of such as inert gas in the appropriate case.One kind can The initial gas mixture of energy is for example normal surrounding air；I.e. by 21 volume % oxygen and 78 volume % nitrogen and 1 body The admixture of gas of product % other gases compositions.However, it is also possible to expect using some the space air for including in closed area As initial gas mixture, thus fresh air is preferably also added into the space air content in room.
Gas separation system is used in particular for keeping the oxygen of the reduction of respective horizontal to contain in the room atmosphere of closed room Amount.Therefore, the fan-out capability of gas separation system, you can with the oxygen provided per unit time in the exit of gas separation system The amount for the admixture of gas that gas reduces, the leakproofness of the space shell particularly suitable for closed area, so as to pass through gas Piece-rate system realizes corresponding continuous flooding.
On the other hand, for system design, it is advantageous that do not use or not only preliminary using gas separation system The oxygen content in the room atmosphere of closed area is reduced, because preliminary reduce needs relatively great amount of indifferent gas per unit time The gas that body or oxygen reduce.In order to only realize that this point, gas separation system must have by gas separation system There is corresponding big construction, this is typically infeasible in terms of cost of investment.
Therefore, other than gas separation system, conventional oxygen reduces system and is usually provided with compressed gas reservoir, The admixture of gas or inert gas that wherein oxygen reduces are stored therein in a compressed format.It is separately stored in compressed gas storage Admixture of gas or inert gas in storage are used in particular for reducing rapidly the oxygen content in corresponding closed area, to send out Oxygen concentration is reduced rapidly when calamity of lighting a fire.But it is also possible to imagine using the gas mixing being stored in compressed gas reservoir Object/inert gas tentatively reduces the oxygen content in corresponding closed area, i.e., specific for oxygen content to be tentatively reduced to Deactivation it is horizontal.
The present invention is based on the problem of proposed after system has been activated is reduced in traditional oxygen, i.e., when in compressed gas Admixture of gas/inert gas that the oxygen that is stored in a compressed format in body reservoir reduces have been incorporated into closed room with When for quick or preliminary reduction, then in order to ensure oxygen reduction system can also be according to pre-determined sequence of events slightly Being realized in time at point afterwards another time quickly reduces, and the compression for having been cleared or partly emptying is replaced with full compressed gas reservoir Gas reservoir is inevitable.
However, in many cases, since the compressed gas reservoir that oxygen reduces system generally can not be in order to freely It obtains and is handled, so can only be by more making great efforts to realize replacement or replacing compressed gas reservoir.Except this it Outside, such case also typically result in operation oxygen reduce system continue the cost is relatively high.
Based on this problem, starting the oxygen of cited type the present invention is based on further development reduces the task of system, To further decrease operating cost when operating oxygen and reducing system the effect or efficiency of system are reduced without damaging oxygen.
The task according to the oxygen of independent claims 1 by reducing system and according to claim 51 for operating oxygen Gas reduces the method for system to solve, and thus indicates that the oxygen of the present invention reduces system respectively in corresponding independent claims The advantageous further development of the method for system or the present invention.
Therefore, a kind of oxygen especially set out reduces system comprising at least one gas separation system, for according to need The admixture of gas that oxygen reduces is provided in the exit of the gas separation system, and for storing oxygen in a compressed format The compressed gas reservoir of admixture of gas or inert gas that gas reduces.Compressed gas reservoir is connected by pipe-line system fluid At least one closed area is connect or can be fluidly connected to, the institute in the compressed gas reservoir will be stored in when needed At least part for stating admixture of gas or corresponding inert gas is supplied at least one closed area.On the other hand, Fluidly connect to the egress selection of the gas separation system or can selectively be fluidly coupled to the compressed gas storage The entrance of storage is fluidly coupled at least one closed area, with when needed by going out in the gas separation system The admixture of gas provided at mouthful is supplied to the compressed gas reservoir and/or at least one closed area.
It can be achieved the advantage that obviously using the solution of the present invention.Pass through the outlet of gas separation system Can selectively be fluidly connected to compressed gas reservoir entrance and/or the present invention oxygen reduction system at least one A closed room, gas separation system have dual function.On the one hand, gas separation system is for mixing the gas that oxygen reduces The room atmosphere for closing object supply closed area, in the room atmosphere to reduce closed area oxygen concentration (=quickly or just Step reduces), or oxygen concentration is maintained at decreased level.On the other hand, gas separation system is used for when needed again Fill at least one compressed gas gas cylinder of compressed gas reservoir.For example, working as in compressed gas reservoir in a compressed format At least part of admixture of gas or inert gas that the oxygen of storage reduces is introduced into the room atmosphere of closed area in advance When middle, such as when so that oxygen concentration therein being reduced rapidly to specific inerting level, this is necessary.By by oxygen In admixture of gas/inert gas " injection " to the space environment of closed room of reduction, this rapid decrease becomes necessary to, Especially when the oxygen concentration in closed room in the event of a fire needs to be decreased as quickly as possible, or in order to first Walk the purpose reduced.
Since at least one gas cylinder of compressed gas reservoir or compressed gas reservoir is able to then pass through gas Piece-rate system refills the admixture of gas of oxygen reduction, therefore no longer needs replacing compressed gas reservoir or compressed gas storage At least one compressed gas cylinder of storage, or compressed gas reservoir is even refilled by external system.Therefore, this programme The closed area that could enter when especially suitable for for example only having any problem, such as the closed area positioned at remote districts.
In principle, the pressurization-gas cascade of compressed gas reservoir or compressed gas reservoir now even can be in sky It is transported and is positioned respectively under state, which greatly simplifies transports and installation.Before initial scene starts, gas segregative line The pressurization-gas cascade for admixture of gas filling compressed gas reservoir/compressed gas reservoir that system is reduced with oxygen first.
In order to optimize the performance of gas separation system, i.e., the gas that the oxygen being capable of providing per unit time reduces is mixed The amount of object is closed, and adapts it to corresponding purposes, it is advantageous that there are compressor assemblies for gas separation system upstream, by this Compressor assembly can correspondingly compress the initial gas mixture that supply to gas separation system.According to operation mode (VPSA or PSA), therefore respectively 1 to 2 bar or 8 to 10 bars of the degree of initial gas mixture compression.But other compressions are worked as So it is also conceivable that.
Gas separation system is specifically designed to isolate at least some oxygen contained in initial gas mixture.
Advantageously, gas separation system is designed to selectively operate with VPSA operation modes or PSA operation modes.
As described above, term " initial gas mixture " used herein is it is generally understood that be special other than oxygen components The admixture of gas of the additional gas of such as inert gas is not contained also containing nitrogen and in the appropriate case also.A kind of possibility Initial gas mixture be for example normal surrounding air；I.e. by 21 volume % oxygen, 78 volume % nitrogen and 1 volume % its The admixture of gas of his gas composition.However, it is also possible to expect using some the space air for including in closed area as just Beginning admixture of gas, thus fresh air be preferably also added into the space air content.
It is the system for providing nitrogen-rich air, basis to be generally understood the gas separation system operated under VPSA patterns The principle of Vacuum Pressure Swing Adsorption (VPSA) works.According to the present invention, such VPSA system is preferably used as in oxygen reduction system Gas separation system, but can be operated when needed with PSA patterns." PSA " acronym represents " pressure-variable adsorption ", leads to Often indicate pressure swing adsorption.
In order to which the operation mode of gas separation system is switched to PSA from VPSA, further development of the invention carries The compression degree of the corresponding initial gas mixture for increasing and being influenced by the compressor assembly of gas separation system upstream is supplied.Especially It is the compression when needing to increase the amount for the admixture of gas that the oxygen that gas separation system exit provides per unit time reduces Degree be increased, depend on the admixture of gas that the oxygen that provides per unit time reduces in particular for increased value Amount.
Especially when fire occurs, i.e., for example when detecting fire characteristic in the room atmosphere in closed area, or Person is due to certain other reasons, compared with earlier set or the oxygen content of maintenance, the oxygen in the room atmosphere of closed area When content further will be reduced quickly, the compression for the initial gas mixture realized by compressor assembly increases.On the other hand, when Such as the compressed gas cylinder of compressed gas reservoir or compressed gas reservoir is respectively necessary for refilling the gas mixing of oxygen reduction When object, the compression increase realized by compressor assembly can also occur.

In a preferred implementation of the oxygen reduction system of the present invention comprising there is the first valve gear, the second valve to fill Set the valve system with third valve gear.Therefore, the first valve gear is configured to going out for foundation as needed/disconnection gas separation system Fluidly connecting between mouth and the entrance of compressed gas reservoir.Second valve gear of valve system be configured to as needed establish/ Fluidly connecting between the outlet of compressed gas reservoir and at least one closed area is disconnected, and third valve gear is configured to root According to need foundation/disconnection gas separation system outlet at least one closed area between fluidly connecting.
Therefore it is preferably provided in a manner of being particularly easy to realize, and the entrance of compressed gas reservoir and compressed gas storage The outlet of storage is by being preferably inside that common connection is connected to compressed gas reservoir, especially with T-piece or wye piece Form.
The oxygen of the present invention reduces the control device for the independent valve gear that system is preferably included for coordinating to activate valve system. Control device is specially constructed to the individual valve gear of actuating valve system so that the outlet when the compressed gas reservoir and institute State between at least one closed area that there is no fluidly connect and/or when the outlet of the gas separation system and at least one envelope There is no when fluidly connecting between closed region, the outlet of the gas separation system is only fluidly coupled to the compressed gas storage The outlet of the entrance of device or the gas separation system is only fluidly coupled at least one compressed gas of compressed gas reservoir The entrance of body container.Certainly, in this case, set different priority it is also conceivable that.
In some embodiments, two or even three individual control devices can also be set：One for distinguishing At least one compressed gas of the outlet of foundation/disconnection gas separation system and compressed gas reservoir or compressed gas reservoir Connection (refilling control) between container, and one or two other is for establishing/disconnecting compressed gas reservoir Export going out for the connection (control is preliminary or quickly reduces and completely inertization) and gas separation system between closed room Connection (maintenance for controlling substantially inertization or oxygen concentration in closed room respectively) between mouth and closed room.

In the oxygen of the present invention reduces a preferred form of system, at least one gas separation system and/or upstream Compressor assembly have first operator scheme and second operator scheme, for as needed by oxygen reduce admixture of gas It supplies at least one pressurization-gas cascade and/or at least one enclosed area of compressed gas reservoir or compressed gas reservoir Domain.For each operation mode, preferably it is also contemplated that separate gas separation system.Therefore, first operator scheme and Second operator scheme can be realized separately or concurrently by independent gas separation system.Gas separation system or at least as a result, The operation mode of one gas separation system and/or the compressor assembly of upstream can preferably (be especially certainly by control device Dynamic ground) control.In this regard it is to be noted that at least one compressed gas of compressed gas reservoir or compressed gas reservoir is held Device is normally filled with the admixture of gas of oxygen reduction, and the nitrogen gas concn for the admixture of gas which reduces extremely is sealed higher than supply The nitrogen gas concn needed for admixture of gas that the oxygen of closed region reduces.
In this way, the oxygen with higher nitrogen gas concn generated in the first operator scheme of gas separation system can be used The admixture of gas (nitrogen gas concn is preferably 99.5 volume %) that gas reduces refills compressed gas reservoir.In gas segregative line The admixture of gas that this oxygen generated in the first operator scheme of system reduces can be incited somebody to action optionally for as needed simultaneously The admixture of gas that oxygen reduces is supplied to closed area, can be equally diluted to it for this, it is therefore an objective to reach enough Nitrogen gas concn, the especially nitrogen gas concn of 95 volume %.In addition, control device provides operating gas point in the second mode of operation Chance from system, wherein providing the gas that the oxygen with enough nitrogen gas concns (nitrogen gas concn is preferably 95 volume %) reduces Mixture, for supplying to closed area.
Thus it is envisioned that when refilling compressed gas reservoir with high nitrogen gas concn, the part of oxygen of generation drops Low admixture of gas is supplied to closed area via bypass.For example, between the outlet and closed area of gas separation system Therefore bypass can be used as together with third valve gear by fluidly connecting.Bypass preferably includes baffle appropriate as a result, will supply The nitrogen gas concn for the admixture of gas that oxygen to closed area reduces is reduced to level appropriate, for example, by by its with it is initial Gas mixing.The beneficial control of gas separation system, is preferably automatically controlled by control device, enabling effectively operate gas Body piece-rate system and the admixture of gas reduced using oxygen according to the effect optimization of the concentration provided.
In addition, in first operator scheme, can again be filled out using a gas separation system using two gas separation systems It fills compression gas reservoir and can use another gas separation system especially concurrently will in second operator scheme The admixture of gas that the oxygen of appropriate nitrogen gas concn reduces is supplied to closed area.Within the meaning of the present invention, it is possible thereby to root According to the compressor assembly for needing to provide public or corresponding individual upstream for multiple gas separation systems.

The present invention is based on traditional oxygen reduce system be activated after the problem of, i.e., when in compressed gas reservoir with The admixture of gas or inert gas that the oxygen of compressed format storage reduces have been transported to closed room with quick or preliminary drop When low, it is often necessary to replace the compressed gas reservoir of consumption.However, in many cases, since oxygen reduces the pressure of system Contracting gas reservoir generally can not be obtained freely, so can only be by more making great efforts to realize replacement or replacing compressed gas Reservoir.In addition to this, the continuous service cost that such case also causes oxygen to reduce system is usually relatively high.In addition, such as Fruit does not lay in compressed gas reservoir, then cannot ensure when replacing compressed gas reservoir or cannot ensure to prevent fires completely.
In view of these problems, the task of the present invention is a kind of oxygen reduction system is proposed, wherein its lasting fortune can be reduced The validity that row cost and oxygen reduce system is unaffected.
Therefore a kind of oxygen reduction system is proposed comprising：At least one gas separation system is used for as needed The admixture of gas that oxygen reduces is provided in the exit of the gas separation system；With a compressed gas reservoir, especially It is one or more pressurization-gas cascades, is used to store the admixture of gas or inert gas of oxygen reduction in a compressed format. Compressed gas reservoir is fluidly connected or be may be connected at least one closed area by pipe-line system, will be stored with as needed At least part of the admixture of gas/inert gas in the compressed gas reservoir is supplied to described at least one Closed area.It thus provides, the outlet of gas separation system fluidly connects or optionally connecting fluid is arrived and/or needed The entrance of compressed gas reservoir and/or at least one closed area are fluidly connected to when wanting, with as needed will be in the gas The admixture of gas that the oxygen that the exit of body piece-rate system provides reduces is supplied to compressed gas reservoir and/or at least one Closed area.
According to the embodiment of hydrogen reduction system, at least one control device is provided at least partly automatically and especially Ground selectively automatically sets up the outlet of gas separation system and the entrance of compressed gas reservoir and/or at least one closing Fluidly connecting between region.
At least one control device is preferably the hardware/software mechanism combined.Such as measurement value sensor or user The input signal of configuration input etc can be handled by least one control device and by means of control software,
Such asTo calculate.Control device may include programmable logic controller (PLC) (PLC), Such as the S7 types that can be obtained from the Siemens AG in Munich, or obtained from the bright WAGO Kontakttechnik GmbH stepped on 750 types obtained.
Oxygen according to the present invention reduces the embodiment of system, and at least one control device is configured as receiving sensor Data, for example to provide information by showing or distributing state or detector data, to actuating compression machine/compressor assembly And gas separation system, and activate valve gear associated with oxygen reduction system.

The another aspect of system is reduced according to oxygen, sensor unit is assigned to control device.Sensor unit is preferred Ground includes at least one pressure sensor and/or at least one temperature sensor.Particularly, pressure sensor and/or temperature pass Sensor measures the state of compressed gas reservoir, especially its fill level or filling extent.It is mixed in the gas reduced with oxygen During conjunction object refills compressed gas reservoir, the temperature in compressed gas reservoir may increase, this causes compressed gas to be stored up Storage not exclusively refills and subsequent pressure is therefore also caused to decline.
It preferably, can be by being more particularly set on compressed gas with the relevant pressure condition of temperature in compressed gas reservoir At least one pressure sensor and/or at least one temperature sensor in body reservoir and/or above is detected, and is passed The admixture of gas for sending to control device, therefore being reduced with oxygen ensures it is basis and temperature to refilling for compressed gas reservoir Spend relevant pressure condition.In this regard, it is also contemplated that control device increases in response to the relevant pressure of temperature and controls or adjust The admixture of gas reduced from compressed gas reservoir release oxygen is saved, and therefore prevents damage compressed gas reservoir.
In the embodiment that oxygen reduces system, at least one gas separation system and/or it is arranged in gas point Compressor assembly from system upstream has first operator scheme and second operator scheme, the gas mixing for reducing oxygen Object is supplied to compressed gas reservoir and/or at least one closed area.Preferably, each operation mode and independent gas point It is associated from system.By doing so, first operator scheme and second operator scheme can pass through independent gas separation system It is operated individually or simultaneously.For this purpose, gas separation system or at least one gas separation system and/or being arranged in gas separation system The operation mode of the compressor assembly of upstream is automatically controlled by control device.In this respect it is noted that It is that the admixture of gas reduced with oxygen refills compressed gas reservoir usually than supply to the nitrogen needed for closed area It is carried out under the higher nitrogen gas concn of concentration.
In this way, when needing to refill compressed gas reservoir, can use in the higher first gas of nitrogen gas concn point From the admixture of gas that the oxygen generated in system operation modes reduces, preferably nitrogen gas concn is 99.5 volume %.In the first gas The admixture of gas generated under body piece-rate system operation mode can also use optionally together, to provide oxygen to closed area Thus then the admixture of gas that oxygen reduces is diluted to the nitrogen gas concn of such as 95 volume % by the admixture of gas of reduction.
Control device provides the further chance of operating gas piece-rate system in the second mode of operation, and mould is operated second Being there is provided in formula has effective nitrogen gas concn, then the admixture of gas that the oxygen that preferably nitrogen gas concn is 95 volume % reduces may be used With supply to closed area.
Therefore for example it is envisioned that when refilling compressed gas reservoir with high nitrogen gas concn, a part of oxygen of generation The admixture of gas that gas reduces is supplied to closed area via bypass.For example, the outlet of gas separation system and closed area it Between fluidly connect therefore can together with third valve gear be used as bypass.For this purpose, bypass preferably includes applicable baffle, it is used for The nitrogen gas concn for being fed to the admixture of gas of the oxygen reduction of closed area or such as mixing chamber is reduced to effective level, The admixture of gas that oxygen reduces in mixing chamber is mixed with initial gas mixture.Advantageously, preferably by control device from Gas separation system is controlled dynamicly to make it possible to effectively operating gas piece-rate system and used according to the concentration optimization provided The admixture of gas that oxygen reduces.
In addition, use two gas separation systems that one gas separation system is operated in the first mode of operation with Refill compressed gas reservoir, and another gas separation system preferably in the second mode of operation parallel work-flow to be envelope Closed region provides the admixture of gas of the reduction of the oxygen under effective nitrogen gas concn.Each gas separation system is imagined as to provide Common or individual upstream compressor system.
The another aspect that system is reduced according to oxygen, provides a kind of system, wherein compressed gas reservoir includes multiple Pressurization-gas cascade, the pressurization-gas cascade is connected in parallel to each other and preferably each pressurization-gas cascade has at least one appearance Device valve.Additionally, it is provided the first collecting and the second collecting.
Therefore, the outlet of gas separation system is connected or connectable to the first collecting via valve, it is therefore preferable to more Each pressurization-gas cascade in a pressurization-gas cascade provides the first pipeline portions, and cell therefor valve is via first pipe Road segment fluid flow is connected to the first collecting.It is preferred that each pressurization-gas cascade in the multiple pressurization-gas cascade The container value is also connected to second collecting via the second pipeline portions.Second pipeline portions itself are special by valve It is not that face valve fluid connects or can be fluidly connected at least one closed area.
In this embodiment, the valve forms aforementioned first valve gear, and the outlet of gas separation system connects via the valve Connect or can be connected to the first collecting.On the other hand, described if oxygen reduction system is associated with multiple closed areas Valve is a part for the second valve gear, the second collecting be connected to via the valve fluid or can be fluidly coupled to it is described at least One closed area.However, if oxygen reduction system is only distributed to single closed area, the valve forms the second valve dress It sets, the second collecting is connected to via the valve fluid or can be fluidly coupled at least one closed area.
The example embodiment of the present invention is described below with reference to attached drawing.
Describe in Fig. 1 the present invention oxygen reduce system 100 the first illustrative embodiments feature particularly in Including gas separation system 102 and other compressed gas reservoir 105.Gas separation system 102 and compressed gas reservoir 105 form oxygen together reduces " inert gas source " of system 100.
Compressor assembly 101 is arranged in the upstream of gas separation system 102, and gas point will be supplied to correspondingly to compress Initial gas mixture from system 102.By suitably changing supply to the initial gas mixture of gas separation system 102 Pressure and volume flow, gas separation system 102 can be adjusted to as defined in the gas that reduces of nitrogen gas concn and required oxygen Body volume.
However, in this regard it is emphasized that corresponding compressor assembly 101 may not be connected to gas separation system 102 upstream.
The outlet of gas separation system 102, the i.e. outlet-of gas separation system 102 provide oxygen in the exit The admixture of gas of reduction or admixture of gas-rich in nitrogen are fluidly connected by the first pipe-line system or can be fluidly connected It is connected or connectable to above-mentioned compressed gas reservoir 105 to closed room 107, and by the second other pipe-line system.For This, in the second pipe-line system (pipe-line system that the outlet of gas separation system 102 is connected to compressed gas reservoir 105) The first valve gear 104 of middle setting.Another valve gear 109 is set in pipe-line system, by the outlet of gas separation system 102 It is fluidly connected with closed room 107.Another valve gear 106 is arranged in one and compressed gas reservoir 105 is connected to closing In the pipe-line system in region 107.This is done so that compressed gas reservoirs 105 can be fluidly connected to closed area when needed 107。
Control device 10, which preferably distributes to oxygen according to the present invention, reduces system 100, so as to the side of coordination Formula controls each valve gear 104,106 and 109.Thus control device 10 is further assigned sensor unit, the sensor list Member has at least one pressure sensor being particularly provided in compressed gas reservoir and/or above compressed gas reservoir And/or at least one temperature sensor.For the sake of clarity, sensor unit is not shown in Fig. 1 to 4.
Specifically, discribed illustrative embodiments, which provide control device 10, is designed to control each valve gear 104,106 and 109 so that when there is no fluids between the outlet and at least one closed area 107 of compressed gas reservoir 105 Connection, i.e., when third valve gear 106 is closed, the outlet of gas separation system 102 is preferably only fluidly connected or can be fluidly connected To the entrance of compressed gas reservoir 105.In addition, control device 10 is designed so that as the outlet of compressed gas reservoir 102 It is not present and fluidly connects between closed area 107, i.e., when the second valve gear 109 is closed, the outlet of gas separation system 102 Compressed gas reservoir 105 is only fluidly connected or can be fluidly coupled to via the first valve gear 104.
Or, it is possible that providing the oxygen of the present invention reduces system 100, especially control device 10 so that gas point Outlet from system 102 can be fluidly connected to compressed gas reservoir 105 via the first valve gear 104 simultaneously when needed Entrance is simultaneously connected to closed area 107 via the second valve gear 109.
In the oxygen of the present invention of Fig. 1 schematic descriptions reduces the illustrative embodiments of system 100, provide another A compressor assembly 103 is arranged in the pipeline system that the outlet of gas separation system 102 is connected to pressurization-gas cascade 105 In system.The other compressor assembly 103 is so that the gas that the oxygen provided in the exit of gas separation system 102 reduces mixes Closing object can be further compressed as needed, so as to be stored in pressurization-gas cascade with desired compressed format In 105.If using compressed gas cylinder or one group of gas cylinder as pressurization-gas cascade, advantageously, other compressor assembly 103 by the oxygen provided in the exit of gas separation system 102 reduce admixture of gas compression up to 300 bars.
The oxygen of schematic depiction reduces the difference of the embodiment of schematic depiction in system 100 and Fig. 1 in Fig. 2 It is, the oxygen of the middle embodiment described reduces system 100 and is not only assigned to single closed area 107 instead of according to fig. 2, Distribute to multiple closed area 107a, 107b.Oxygen reduces system 100 and is therefore implemented as so-called multizone system.
With Fig. 1 illustrated embodiments another difference is that, the oxygen that is schematically shown in Fig. 2 reduces system 100 Compressed gas reservoir 105 includes multiple the pressurization-gas cascade 105a, 105b, 105c, 105d being spatially separating being connected in parallel. These pressurization-gas cascades are, for example, commercially available gas cylinder (300 bars of gas cylinders).
Individual pressurization-gas cascade 105a to 105d is connected in parallel with each other, so as to needing to be as quickly as possible will The admixture of gas stored in a compressed format in these pressurization-gas cascades 105a to 105d is supplied to closed area 107a, 107b。
First collecting 110 and the second collecting 111 are for implementing of being schematically shown in Fig. 2 during which is Pressurization-gas cascade 105a's to 105d is connected in parallel.First collecting 110 can be fluidly connected via the first valve gear 104 To the outlet of gas separation system 102.
As equally in Fig. 1 in the embodiment example of schematic depiction, oxygen shown in Fig. 2 reduces system 100 and uses The outlet of gas separation system 102 is as needed connected to the first closed area 107a and/or the second envelope by another valve gear Closed region 107b.However, compared with the embodiment example schematically shown in Fig. 1, which includes two valve 109a in total And 109b, each valve is designed as face valve and distributes to corresponding closed area 107a, one of in 107b.

Fig. 6 shows the flow chart for the exemplary control sequence that system is reduced for control example oxygen as shown in Figure 1.
The left branch of Fig. 6 shows closed area 107a, tentatively reduces and/or keep oxygen to reduce the sequence of concentration in 107b It arranges (" substantially inertization " pattern).The right branch of Fig. 6 shows for detection, fire extinguishing (" completely inertization " pattern) and compresses The sequence of gas container 105a to 105d refilled.
Two sequences are shown for the example of closed area 107a.Closed area 107b can certainly expect such Sequence.Two sequences as shown in the left and right side branch of Fig. 6 can individually or concurrently occur.
The left branch (" substantially inertization " pattern) being related in Fig. 6 is described below：
Closed area 107a, the oxygen concentration in 107b are continuously measured during the operation that oxygen reduces system, and will be surveyed Amount data are supplied to control device 10.When reaching preset maximum oxygen concentration, control device 10 is opened valve 109a and is opened The compressor assembly 101 of dynamic upstream, the i.e. upstream of gas separation system 102 and gas separation system 102, so as to by oxygen The admixture of gas of reduction is supplied to closed area 107a.Once reaching preset minimum oxygen concentration, control device 10 just stops Only the compressor assembly 101 and gas separation system 102 of upstream and close valve 109a.
Due to closed area 107a, the leakage of 107b causes oxygen concentration to rise naturally, therefore is finally reached maximum concentration, And thus the restarting of the compressor assembly 101 and gas separation system 102 of triggering upstream.
Cmin and maximum concentration can be individually defined and stored in control device 10.Cmin can be in example It is 17.0 volume %, and maximum concentration can be 17.4 volume % in example, typical substantially inertization model will be corresponded to It encloses.
Further example includes the lower limiting value and upper limit value of 14.0 volume % and 14.4 volume %, this will correspond to typical case Completely inertization range.In order to improve fire protection efficiency, Cmin and maximum concentration can also changeably be defined as daytime and Night mode, wherein day mode indicate the time with high flow of the people in closed area, need higher oxygen concentration, and And wherein night mode indicates the time for only having little or no people to enter closed area, this so that oxygen concentration is lower.
The right branch for being related to Fig. 6 is described below, fills out it illustrates detection, fire extinguishing (" completely inertization " pattern) and again Interaction between filling：
Detection can be realized by aspirated smoke detector, so as to realize very useful, reliable and tool There is the fire alarm system of visual attraction.If detecting fire in the 107a of closed area, detection signal is controlled from fire alarm Panel 121 is sent to control device 10.Therefore control device 10 opens valve 106a and starts pressurization-gas cascade 105a to 105d, With via collection circuit 111 and valve 106a discharges so that the oxygen being stored in pressurization-gas cascade 105a to 105d reduced Admixture of gas quickly enters closed area 107a, to put out a fire.
Once the oxygen concentration in the 107a of closed area reaches minimum value, extinguishes or inerting pattern completely is just by closing valve 106a and terminate.With the startup of the compressor assembly 103 of the opening and downstream of valve 104, automatic or manual refills beginning.
It is continuous to measure container pressure and measurement data is conveyed to control device 10.Pressurization-gas cascade 105a is to 105d quilts It refills until pressure reaches preset maximum value.In a preferred embodiment, pressure measuring value is subjected to temperature-compensating.This is logical It crosses and measures pressure and temperature in pressurization-gas cascade 105a to 105d and by according to Thermodynamics Formulas normalized pressure Power is completed.Minimum and maximum pressure can be individually defined and stored in control device 10.
Stop the compressor assembly 103 in downstream by control device 10 and closes valve 104 to complete to refill.Then system It is restored to such a pattern, system is for about closed area 107a, the fire alarm that 107b is provided is sensitive in this mode Ground reacts, hence into stand-by state, further quickly to be reduced in resume combustion or another fire or completely inert Change.
The present invention is not limited to the embodiments that the oxygen of schematic depiction in attached drawing reduces system 100, but are examined from synthesis Consider all features disclosed herein and generates.
In this case especially it is conceivable, that another buffer is set up directly on the outlet of gas separation system Place, the admixture of gas that the oxygen that the exit to be stored temporarily in gas separation system provides reduces.
The preferential realization that system 100 is reduced according to oxygen, provides and utilizes gas separation system (nitrogen gas generator), the gas Piece-rate system (gas generator) is kept fixed with required other downstream high pressure compressor (compressor assembly 103), equally It is kept fixed or is arranged to moveable.
However, if not needing additional structure investment (high pressure fills pipeline, valve etc.) for specifically application, then it is complete Complete moveable variant (gas separation system 102, two compressor assemblies 101,103) is advantageous.
In an alternative solution, stationary gas piece-rate system can be supported by mobile gas piece-rate system, otherwise The size by stationary gas piece-rate system is just needed to be set to bigger to carry out possible refill to generate necessary confession It should export.It is likewise contemplated that providing two stationary gas piece-rate systems, (one is used for continuous flooding, and one is used in principle Refill) possibility.
If (only) providing one, especially stationary gas piece-rate system, then advantageously allow hand in gas point Nitrogen gas concn from the admixture of gas that the available oxygen in the exit of system reduces.It is put into the best supply condition in room For prove, nitrogen gas concn is about 95 volume %, however, in order to optimize the quantity of gas pressure vessel, be preferably filled with to Few 98 volume %, preferably at least 99 volume %.
Other than the gas pressure (storage pressure) being stored in compressed gas reservoir, compressed gas reservoir is monitored Temperature (gas cylinder temperature) be advantageous.This is not only respectively used to the pressure measurement or filling of temperature-compensating, but also is used for Filling is terminated when more than maximum temperature, to protect container value.Temperature can be surveyed for example, by the magnetic thermal element on gas cylinder outer wall Amount.Preferential measuring temperature, i.e. most cold spot and hottest point at least at two points of compressed gas reservoir.Most cold spot and hottest point It can be determined, or can be estimated according to ambient enviroment by testing in advance, for example, in nice and cool metope or radiator On the basis of.Temperature at most cold spot is subsequently used for pressure measurement/filling of temperature-compensating, and the measurement at hottest point is intended to prevent More than the maximum temperature that may damage container value.
It is also advantageous that the remnant oxygen content in monitoring gas separation system exit, the air reduced so as to nitrogen is not It can be imported into compressed gas reservoir, but external or closed area is transferred in the low nitrogen gas concn not allowed, To ensure required purity.
