Specific implementation mode
In order to better understand the present invention, the present invention is further retouched with reference to specific embodiments and the drawings
It states.
As shown in Figure 1, the present invention provides a kind of pressure charging system of gas-steam combined unit, the gas-steam combined
The pressure charging system of unit includes multigroup pressure piping 300 being arranged in parallel, and every group of pressure piping 300 is both provided with pressure regulation unit
200 and be set to 200 downstream of pressure regulation unit, and with 200 concatenated compress cell 100 of the pressure regulation unit.
The regulative mode that the present invention is combined using compress cell and pressure regulation unit so that this pressure charging system adapts to combustion gas completely
The various pressure limits of pipe network.
Further, as shown in Fig. 2, the compress cell 100 includes compressor 101, the compressor 101 enters tracheae
It is disposed with sucking isolating valve 103 on road 102 and sucks control valve 104, on the outlet pipe 107 of the compress cell 100
It is disposed with outlet bleed valve 108 and outlet isolating valve 109.
Natural gas enters air pipe 102 and enters the compressor 101 described in passing through, by the compressor 101 by natural air lift
The pressure value needed for combustion engine is risen to, the effect of the sucking control valve 104 is to adjust the natural gas for entering the compressor 101
Pressure value keeps it in setting value, to ensure 11 stable operation of the compressor.
Further, the arrival end of the compressor 101 and outlet end are connected with cooling for reflux pipeline 110, the cooling
Reflux cooler 114 and return valve 111 are provided on return line 110.When the return valve 111 is opened, part is natural
Gas is carried out by returning to the inlet of the compressor 101 after the reflux cooler 114 by the compressor 101 again
Boosting.
As shown in figure 3, Fig. 3 is the schematic diagram of the performance atlas of the compressor 101.By the performance of the compressor 101
Shown in collection of illustrative plates, the working region of the compressor 101 is divided into stable and unstable region, surge and appears in unstable region.For
Prevent surge, compressor 101 of the invention is equipped with return valve 111.When operating point enters unstable region, i.e., will breathe heavily
When shaking, by opening the return valve 111, the flow of medium in the compressor 101 can be improved, operating point is made to return to stabilization
In region.For this purpose, on the right side of surge line, it is parallel with surge line to be equipped with a control line.Meanwhile in surge line and control
One safety line is set between line.The task of the return valve 111 is that operating point is made to be maintained at stability region.
Further, it is additionally provided with nitrogen charging pipeline 105 between the sucking isolating valve 103 and the sucking control valve 104,
It is provided with nitrogen fill valve 106 on the nitrogen charging pipeline 105.
Further, frequency converter, the driving electricity of the frequency converter and the compressor are additionally provided on the compressor 101
Machine connects.
The compress cell 100 first has to carry out nitrogen charging to system, so that the dry gas to the compressor is close before work
Envelope system is for nitrogen.
During nitrogen charging, the inlet isolation valve 103, the outlet bleed valve 108 and the outlet isolating valve 109 are equal
It is closed, the nitrogen fill valve 106, the inlet control valve 104 and the return valve 111 are in open state.
It is the pressure that source nitrogen with certain volume flow and pressure during nitrogen charging, which passes through the nitrogen charging pipeline 105,
Contracting machine 101 is carried out for nitrogen.
It needs to pressurize to system with fuel gas after nitrogen charging.In this process, the outlet bleed valve 108 and outlet
Isolating valve 109 is still within closed state, and the inlet isolation valve 103 and return valve 111 are in open state, and to close
Close the inlet control valve 104.It is closed in the inlet control valve 104 and then opens its part, fuel gas supplies at leisure
To the increasing compressor 101, when 101 internal pressure of the compressor and equal supply gas pressure, the inlet control valve 104 closes
It closes, while the outlet bleed valve 108 is opened so that nitrogen/fuel gas gaseous mixture in the compressor 101 goes out described in
Mouth bleed valve 108 is discharged.During discharge, 111 inductive switch of the return valve alternately, until the compressor 101
Internal nitrogen gas component is reduced within the scope of permissible value.Then, the outlet bleed valve 108 must shut off, at this point, the compression
Fuel gas is had been filled in machine 101.
Further, need to start the compressor 101, at this point, the inlet isolation valve 103, inlet control valve 104,
Return valve 111 and the outlet isolating valve 109 are in open state, and the outlet bleed valve 108 is closed.This process
In, the fuel gas flows to downstream from the compressor 101.
Further, frequency converter, the driving electricity of the frequency converter and the compressor are additionally provided on the compressor 101
Machine connects.The compressor 101 is set to switch under power frequency and variable mode.
It is tieed up by adjusting the speed of the valve position and driving motor of the return valve 111 and the inlet control valve 104
Hold the pressure value of system.
The present invention realizes the continuous change of compressor using the control mode of suction control valve, return valve and frequency converter
Frequency modulation section and Anti-surge Control extend the operating condition range of compressor so that compressor can be according to combustion engine operating status
The most matched operating condition of selection, substantially increases adaptability of the compressor to air supply pressure fluctuation, while improving compression
The energy-saving effect of machine.
Fig. 3 and Fig. 4 is the suction control valve of the present invention, the control mode of return valve and frequency converter and traditional air-breathing control
The control mode speed adjustable range comparison diagram of valve processed, adjustable vane, return valve and frequency converter.In the present invention, due to being no longer arranged
Adjustable vane so that compressor can the continuous stepless frequency conversion adjusting of (figure dash area) progress.And due to can in traditional scheme
Adjust the presence of guide vane so that compressor forms many places interval of resonance in frequency converter adjustable extent, to avoid resonating, pressure
Contracting machine can only work under specific several groups of rotating speeds, and power shows the relation property of multiple-rank control with discharge characteristic, thus
Bring that unit control characteristic is poor, the relatively low problem of energy-saving effect, as products different Fig. 4 can actually be divided into 5~8 grades of adjustings
Differ.
Further, the pressure regulation unit 200 includes a pressure regulation pipeline 201, and the pressure regulation pipeline 201 is single with the supercharging
Member 100 enters the connection of air pipe 102, and pressure regulator valve 202 is provided on the pressure regulation pipeline 201.
The present invention is provided with compress cell 100 and pressure regulation unit 200, using 200 groups of compress cell 100 and pressure regulation unit
Regulative mode is closed, adapts to the various pressure limits of gas ductwork completely.When ductwork pressure is in 2.5~3.6MPa with compress cell
Based on 100 adjustings, supplemented by the adjusting of pressure regulation unit 200, the pressure regulation unit 200 is merely responsible for the amendment of pressure oscillation, under guarantee
Swim pressure stability；Ductwork pressure>When 3.6MPa, the regulating valve of pressure regulation unit 200 is responsible for controlling pressure and stablizing in 3.6MPa
Below so that 100 guarantee of run steady downstream pressure of compress cell is stablized；When ductwork pressure is increased to combustion engine safe operating conditions
When, the compressor stopping is spare, and the control of pipeline atmospheric pressure in 112 future is got in touch with about in 4.3MPa by described second.
Further, as shown in figure 5, the discharge chambe 1011 of compressor 101 is connected with sealing room 400, the sealing room 400
