Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, atmospheric valve, 2, the return line modulating valve, 3, air inlet pipeline cut-offs valve.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below through embodiment, and combine its accompanying drawing, the utility model is set forth in detail.
By shown in Figure 1, be provided with first pressure-detecting device, press, second pressure-detecting device, compensator or trimmer pressure jar, air inlet pipeline successively at the air inlet pipeline upper edge inflammable gas direct of travel that is connected with the suction port of gas turbine generator and cut-off valve 3.On the air inlet pipeline before first pressure-detecting device and be connected to an atmospheric valve 1.Air inlet pipeline before first pressure-detecting device and an end of return line also connect, and the other end of return line is attempted by second pressure-detecting device and air inlet pipeline cut-offs on the air inlet pipeline between the valve 3, on return line, is provided with return line modulating valve 2.Atmospheric valve 1, first pressure-detecting device, second pressure-detecting device, air inlet pipeline cut-off valve 3, return line modulating valve 2 and are connected with control gear through lead respectively; Press is connected with frequency variator through lead, and frequency variator is connected with control gear through lead.First pressure-detecting device and second pressure-detecting device can be pressure transducer, and atmospheric valve 1 can be pneumatic atmospheric valve.
Wherein, the air inlet pipeline before the press is a low pressure area, and the air inlet pipeline between the suction port of press and gas turbine generator is middle nip.First pressure-detecting device and second pressure-detecting device are respectively control gear required air inlet pipeline low pressure area barometric information of Regulation Control and middle nip barometric information are provided, and control gear is handled these data and controlled the relevant device action afterwards.The compensator or trimmer pressure jar is that gas flow changes the excessive device of nip gas pressure change in the pipeline that causes when slowing down because of the gas turbine generator increasing and decreasing load; It can make the pressure of the inflammable gas that gets into gas turbine generator more stable, with guarantee gas turbine generator steadily, operation efficiently.
During work; Inflammable gas cut-offs valve 3 through first pressure-detecting device, press, second pressure-detecting device, compensator or trimmer pressure jar, air inlet pipeline and gets into gas turbine generator; Low pressure combustible gas body before the press becomes the middle pressure inflammable gas that can supply gas turbine generator to use after the press supercharging; Control gear can be according to the gas pressure value in first pressure-detecting device and the detected pipeline of second pressure-detecting device; Through the Frequency Converter Control press, the gas pressure in regulating in the nip air inlet pipeline makes it keep stable.When the middle nip barometric information that second pressure-detecting device feeds back to control gear reaches predefined value; Control gear transmission instruction is cut-off valve 3 to air inlet pipeline opens it; Guaranteed that like this gas pressure that gets into the gas turbine generator suction port keeps stable, prevents that gas turbine generator is because of insufficient tempering of burning.After control gear is handled the pressure data of first pressure-detecting device and second pressure-detecting device feedback; Show that nip air pressure raises in the air inlet pipeline; When surpassing the security value (s) of setting; Control gear sends instruction and gives frequency variator, controls the outlet pressure of press through the frequency of regulating frequency variator output.When frequency variator was out of control, control gear sent instruction and makes its outlet pressure of regulating press for return line modulating valve 2, and nip gas flows to low pressure area through return line in making, and gas pressure reduces in the middle nip air inlet pipeline, to guarantee pipeline safety.After control gear is handled the pressure data of first pressure-detecting device and second pressure-detecting device feedback; Show that air inlet pipeline low pressure area air pressure raises; When surpassing the security value (s) of setting; Control gear sends instruction and it is opened for atmospheric valve 1, discharges the gas in the air inlet pipeline, to guarantee pipeline safety.
