Therefore a kind of scheme of protecting compressor safe operation is provided, and has been a problem of needing solution badly.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art; the invention provides a kind of synthesic gas compressor high-pressure cylinder synthesis stage and circulation section dividing plate protective system that is simple and easy to enforcement; for the protection of synthesic gas compressor high-pressure cylinder synthesis stage and circulation section dividing plate; prevent that synthesic gas compressor is in operation because dividing plate pressure-bearing distortion is damaged compressor compared with causing greatly.
The object of the present invention is achieved like this:
Synthesic gas compressor high-pressure cylinder synthesis stage and circulation section dividing plate protective system, comprise synthesic gas compressor low pressure (LP) cylinder 1, and synthesic gas compressor low pressure (LP) cylinder 1 connects steam turbine 2, and steam turbine 2 connects synthesic gas compressor high-pressure cylinder 3; Virgin gas inlet line 4 connects synthesic gas compressor low pressure (LP) cylinder 1, and synthesic gas compressor low pressure (LP) cylinder 1 connects synthesic gas compressor high-pressure cylinder 3 synthesis stages by pipeline, and synthesic gas compressor high-pressure cylinder 3 synthesis stages connect virgin gas outlet line 5; Circulating air inlet line 6 connects synthesic gas compressor high-pressure cylinder 3 circulation sections, the 3 circulation section outlets of synthesic gas compressor high-pressure cylinder connect circulating air outlet line 7, it is characterized in that: the virgin gas outlet line 5 that synthesic gas compressor high-pressure cylinder 3 synthesis stages connect is connected with circulating air outlet line 7 by connecting pipeline 8; On connecting pipeline 8, be provided with urgent interlocking and be communicated with modulating valve 9; On synthesic gas compressor synthesis stage virgin gas outlet line 5, be provided with the interlocking atmospheric valve 10 that stops in emergency; Teletransmission pressure reduction instrument 11 is set between synthesis stage virgin gas outlet line 5 and circulating air inlet line 6;
Described teletransmission pressure reduction instrument 11 possesses warning function, and alarming value is lower than the pressure-bearing value of dividing plate between synthesic gas compressor high-pressure cylinder synthesis stage and circulation section.
actively beneficial effect: the present invention is by the time reaching alarming value or synthesic gas compressor and stop in emergency in teletransmission pressure reduction instrument, urgent interlocking is communicated with modulating valve standard-sized sheet, keep virgin gas consistent with circulating air pressure, and from the pressure release of synthesic gas compressor high-pressure cylinder virgin gas outlet parking interlocking atmospheric valve, avoid occurring causing because pressure reduction is excessive dividing plate distortion, damage compressor.
Accompanying drawing explanation
Fig. 1 is system architecture schematic diagram of the present invention;
In figure, be: synthesic gas compressor low pressure (LP) cylinder 1, steam turbine 2, synthesic gas compressor high-pressure cylinder 3, virgin gas inlet line 4, virgin gas outlet line 5, circulating air inlet line 6, circulating air outlet line 7, connecting pipeline 8, urgent interlocking are communicated with modulating valve 9, stop in emergency interlocking atmospheric valve 10, teletransmission pressure reduction instrument 11.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1, synthesic gas compressor high-pressure cylinder synthesis stage and circulation section dividing plate protective system, comprise synthesic gas compressor low pressure (LP) cylinder 1, and synthesic gas compressor low pressure (LP) cylinder 1 connects steam turbine 2, and steam turbine 2 connects synthesic gas compressor high-pressure cylinder 3; Virgin gas inlet line 4 connects synthesic gas compressor low pressure (LP) cylinder 1, and synthesic gas compressor low pressure (LP) cylinder 1 connects synthesic gas compressor high-pressure cylinder 3 synthesis stages by pipeline, and synthesic gas compressor high-pressure cylinder 3 synthesis stages connect virgin gas outlet line 5; Circulating air inlet line 6 connects synthesic gas compressor high-pressure cylinder 3 circulation sections, the 3 circulation section outlets of synthesic gas compressor high-pressure cylinder connect circulating air outlet line 7, and the virgin gas outlet line 5 that synthesic gas compressor high-pressure cylinder 3 synthesis stages connect is connected with circulating air outlet line 7 by connecting pipeline 8; On connecting pipeline 8, be provided with urgent interlocking and be communicated with modulating valve 9; On synthesic gas compressor synthesis stage virgin gas outlet line 5, be provided with the interlocking atmospheric valve 10 that stops in emergency; Teletransmission pressure reduction instrument 11 is set between synthesis stage virgin gas outlet line 5 and circulating air inlet line 6, possesses warning function, and be made into the locking system that stops in emergency.
Described teletransmission pressure reduction instrument 11 possesses warning function, and alarming value is lower than the pressure-bearing value of dividing plate between synthesic gas compressor high-pressure cylinder synthesis stage and circulation section.
As shown in Figure 1, the virgin gas (mixed gas of nitrogen and hydrogen) of synthetic ammonia enters synthesic gas compressor low pressure (LP) cylinder 1 by virgin gas admission line 4 and compresses, gas after two sections of compressions enters synthesic gas compressor high-pressure cylinder 3 synthesis stages and further compresses, and enters synthesis ammonia system after reaching setting pressure by virgin gas outlet line 5; Further compress through the synthesis ammonia system circulation section that hydrogen of synthetic ammonia and nitrogen do not enter synthesic gas compressor high-pressure cylinder 3, then come back to synthesis ammonia system by circulating air outlet line 7 and carry out ammonia synthesis, thereby improve the productive rate of synthetic ammonia; Teletransmission pressure reduction instrument 11 reaches alarming value (alarming value setting is lower than dividing plate pressure-bearing) or synthesic gas compressor while stopping in emergency, urgent interlocking is communicated with modulating valve 9 standard-sized sheets, synthesic gas compressor high-pressure cylinder circulation section is communicated with synthesis stage outlet through connecting pipeline 8, keep virgin gas consistent with circulating air pressure, open the interlocking atmospheric valve 10 that stops in emergency simultaneously, pressurized gas, by interlocking atmospheric valve 10 pressure releases of stopping in emergency, are avoided occurring causing because pressure reduction is excessive dividing plate distortion.
