Additional features of the present invention describes the middle with reference to the accompanying drawings embodiment who describes.Accompanying drawing is:
Description has the structural drawing of the intermediate storage mean that flows through clean gas of the high-pressure storage of the low-voltage memory of two parallel connections and two parallel connections,
People can identify gas distribution ducts 1 in diagram is described, so-called clean gas that generated by the device of a gasification of coal that does not occur in the accompanying drawings and that purified in the purifier 2 that connects has thereafter passed through and should conduct to the firing chamber of a gas turbine and other user 4 by pipe 1,5, ethanol synthesizer for example.The intermediate storage device 6 that flows through clean gas that is connected on this gas distribution ducts 1 has two low-voltage memories 7 in an embodiment, 8 and two high-pressure storages 9,10, two low-voltage memories 7 of one side, 8 two high-pressure storages 9 on the other hand parallel with one another, 10 is parallel with one another, and low-voltage memory and high-pressure storage are coupled to each other by a total connecting conduit 11.This connecting conduit has been equipped two intermediate compressor 12,13 of series connection mutually in an embodiment.All there is an interstage cooler directly to be connected in thereafter for each intermediate compressor.The rebound valve 16 of also having packed on this external connecting conduit 11.
In these two low-voltage memories 7,8 each is isolated air inlet duct 17,18 through one and is connected to that gas distribution ducts 1 gets on again.In this air inlet duct, both load onto 19,20, air inlet adjustment valve 21,22 of a butterfly gate, also loaded onto a rebound valve 23,24.It is joining with each pressure transducer 25,26 that is contained on the gas distribution ducts that valve is adjusted in two air inlets, the maximum allowble pressure of this gas distribution ducts of can adjusting at the pressure transducer place.These air inlets are adjusted valve 21,22 or are correspondingly also had the butterfly gate 19 of packing on the air inlet duct 17,18 in addition, 20 another pressure transducers 27,28 that are connected on the low-voltage memory 7,8 of process link up, this pressure transducer can be adjusted on the maximum allowable pressure in low-voltage memory 7,8.In low-voltage memory in order to limit the storage temperature corresponding cooler 29,30 of having packed into.In low-voltage memory 7,8 air inlet ducts 17,18, can consider to have at least an auxiliary cooler 31,32 to be used to cool off the clean gas of inflow at last.
At the low-voltage memory 7 that links with connecting conduit 11, in 8 the outtake tube 33,34, remove a butterfly gate 35,36 and rebound valve 37, outside 38, also has low pressure blocking-valve 39,40 of giving vent to anger, it is subjected to one and is connected on the low-voltage memory, and the adjusting of the pressure transducer of adjusting according to the maximum allowble pressure in the low-voltage memory 7,8 41,42.
On the outtake tube 43,44 of each in two high-pressure storages 9,10, remove one and block that mechanism 45,46 and rebound valve 47,48 are outer to also have so-called high pressure modulating valve 49,50 of giving vent to anger.These modulating valve of giving vent to anger can be regulated by being connected on the gas distribution ducts 1 and with the pressure transducer 51,52 that its minimum authorized pressure is adjusted.It or not the high pressure modulating valve 49 of giving vent to anger, 50, be exactly correspondingly at high-pressure storage 9, two outtake tubes 43 of 10, the obstruction mechanism 45 that introduces on any in 44, in 46 each is subjected to and is joining with high-pressure storage, and the adjusting of the pressure transducer of being adjusted by minimum pressure that high-pressure storage allows 53,54.High-pressure storage 9,10 removes by one and blocks outside mechanism 55,56 and the rebound valve 57,58, also links by a corresponding air inlet blocking-valve 59,60 and connecting conduit 11.Each air inlet blocking-valve 59,60 is via being connected on the high-pressure storage 9,10, and regulates with the pressure transducer 61,62 that its pressure maximum is adjusted.
In an embodiment with these two high-pressure storage 9,10 parallel connections a high pressure bypass air inlet duct 64 with single booster compressor 63, it also is furnished with and blocks mechanism 65, rebound valve 66 and motor control valve 67.Back at the middle booster compressor 63 of high pressure bypass air inlet duct 64 has connected a heat exchanger 68.Also show a low pressure bypass air inlet duct 69 that adopts corresponding to high pressure bypass air inlet duct 64 in an embodiment.It links up the low voltage side of gas distribution ducts 1 and connecting conduit 11.In this low pressure bypass air inlet duct 69, be provided with a motor modulating valve 70, it and obstruction mechanism 71, rebound valve 72 is in series.Also introduced an auxiliary cooler 73 that is used to cool off clean gas in an embodiment here.
If reduction along with clean gas consumption, the for example decline of combustion turbine power, pressure in the gas distribution ducts 1 has risen, be contained in the pressure transducer 25 on the gas distribution ducts so, 26 when surpassing it and give the pressure maximum of adjusting at low-voltage memory 7, air inlet adjustment valve 21,22 on 8 suction tude 17,18 is regulated.This air inlet adjustment valve 21,22 also through a selector switch (not shown on accompanying drawing) interlocking reciprocally in the following manner: promptly only can only have one to be regulated by affiliated pressure transducer at every turn, or close for another or the maintenance always always of a plurality of air inlet duct each time.In the low-voltage memory under superfluous now clean gas flows into via air inlet duct that is conditioned and dress auxiliary cooler thereon.Its meaning is here: the pressure in the low-voltage memory is on the numerical value that is lower than the minimum pressure in the gas distribution ducts constantly.This low-voltage memory 7 or 8 has been drawn superfluous clean gas on the working position with respect to the air inlet adjustment valve of being regulated by sensor 25,26 21 or 22 now, has consequently kept minimum pressure in the gas distribution ducts.When if this low-voltage memory reaches its maximum allowable pressure by this way, the pressure transducer 27,28 that is contained in so on the low-voltage memory 7,8 just regulates the air inlet adjustment valve to cutting out, and has passed through selector switch and has regulated another air inlet adjustment valve and open.The pressure transducer 25 or 26 that will lead in another conduit now under it is regulated corresponding to air feed in the gas distribution ducts 1 or gas pressure.In an embodiment the adjusting conduit of the pressure transducer 27,28 on the low-voltage memory 7,8 each link with air inlet adjustment valve 21,22 respectively.At this, with being connected on that sensor on the low pressure storage is not controlled suction valve and the butterfly gate 19,20 of controlling serial connection also is possible.
As long as in the low-voltage memory 7,8 one reaches its pressure maximum that gives adjusting and during with 1 blocking-up of gas distribution ducts, will regulate the low pressure blocking-valve 39,40 of giving vent to anger by switching logic device and another pressure transducer that connects with low-voltage memory 41,42
*, then begin the intermediate compressor 12,13 in connecting conduit and regulate the air inlet blocking-valve 59,60 of high-pressure storage.To be pumped emptyly again with this low-voltage memory of having been filled with of the method, and in the high-pressure storage one will charge into by pump and take out the clean gas that comes.
The pressure transducer 61,62 of sensing maximum allowble pressure is housed on each in the high-pressure storage 9,10.Be closed when this high-pressure storage has reached its pressure maximum by these affiliated air inlet blocking-valves that pressure transducer 61,62 makes and connecting conduit 11 links, and another air inlet blocking-valve is opened.
If when the gas pressure in gas distribution ducts 1 drops to minimum, this high pressure modulating valve 49 of giving vent to anger, 50 will be by pressure transducer 51,52 are adjusted to unlatching according to the minimum pressure of adjusting of giving in the gas distribution ducts, necessary to remain in the gas distribution ducts, give the minimum pressure of adjusting.
In order to reduce to influence the unstable state of degree of regulation, only allow to have in two high-pressure storages parallel with one another a gas wherein to be evacuated simultaneously.If when the pressure in high-pressure storage is reduced to the minimum pressure values of being adjusted, so will by means of with the joining pressure transducer 53 of this high-pressure storage, 54, or control is by the affiliated high pressure modulating valve 49 of giving vent to anger, 50, or control is closed by the obstruction mechanism 45,46 that is arranged in same outtake tube.By means of one on accompanying drawing unshowned switching logic device will side by side make give vent to anger modulating valve or block mechanism and handled or be adjusted to unlatching of the high pressure of the high pressure storage device that another remains to be inflated.The give vent to anger working position of modulating valve of this high pressure will be decided by affiliated pressure transducer 51,52.Therefore at this moment the task of continuing the clean gas of conveying in gas distribution ducts 1 will be born by another high-pressure storage.Interlocking by corresponding single valve has just guaranteed safety, makes any high-pressure storage side by side both not inflated by intermediate compressor 12,13 and carries out air feed to gas distribution ducts 1.Therefore blocking mechanism 45,46 when opening and the high pressure on the same outtake tube 43,44 give vent to anger modulating valve 49,50 when opening, always side by side make the air inlet blocking-valve 59,60 of same high-pressure storage close by means of affiliated manipulation logic device (not shown in the accompanying drawing).
And the valve of two-way low-voltage memory 7,8 also utilizes similar form to interlock mutually.Consequently when the clean gas that comes out from gas distribution ducts 1 via air inlet duct 17, during 18 in these low-voltage memories one inflation, the neither one low-voltage memory can meanwhile be evacuated gas by the intermediate compressor of introducing 12,13 on connecting conduit.Therefore when an air inlet adjustment valve is opened, utilize the manipulation logic device side by side to close low pressure on the same low-voltage memory blocking-valve of giving vent to anger.Similarly, if need not before chat way, also can be imposed on as above adjusting with butterfly gate 19,20 with respect to the low pressure blocking-valve 39,40 of giving vent to anger.Reduced the unstable state that the adjusting rugosity to air inlet adjustment valve 21,22 has a negative impact by means of the reciprocal interlocking of the air inlet duct of the reciprocal interlocking of the air inlet of each low-voltage memory itself and outtake tube and two storages parallel with one another and outtake tube.
In order to be equilibrated at gas surplus more in the gas distribution ducts, can be put into operation at this high pressure bypass air inlet duct 64 that flows through in the intermediate storage device 6 of clean gas, the motor modulating valve 67 under will opening from a monitoring station simultaneously also puts booster compressor 63 into operation.More whereby gas interference can directly be stored up in the middle of into high-pressure storage 9,10 one, this gas by high pressure bypass air inlet duct draw can by one in the low-voltage memory alternatively or affix ground realize.In addition, in order to address this problem, the also available following more gas surplus of method intercepting: as what describe in an embodiment, consider to realize with a low pressure bypass air inlet duct 69, adjustment by the motor modulating valve 70 of packing at there, on the gas flow volume of surplus is pumped into one in the high-pressure storage 9,10 via connecting conduit 11 with respect to definite pump power of intermediate compressor 12,13 time.When the absorption of more gas excess quantity, operation high pressure bypass air inlet duct 64 or low pressure bypass air inlet duct 69 is both economical practices, because be the higher pressure reference from the gas distribution ducts, rather than lower pressure reference sets out to decide and must carry out pressurized gas from low-voltage memory 7,8.
Because regulation technology, 67,70 o'clock be the butterfly gate 19,20 of side by side closing on the air inlet duct 17,18 of low-voltage memory always opening the motor modulating valve.By means of at single compressor 12; Interstage coolers 14,15 that 13 backs connect and at air inlet duct 17,18 are connected in the auxiliary cooler of its front in 69, can make that the gas temperature in the single storage in 7 to 10 is limited in the maximum numerical value that allows.Storage volume in these storages just obtains improving whereby.Allowing the temperature of itself to remain on one at the cooler of packing on the low-voltage memory gives on the fixed temperature reference.
