Embodiment
In the drawings, after gas compressed by compressor (1), pressure gauge (3) and pressure transmitter (2) can directly embody the gas pressure after the compression, and thermometer (4) and temperature transmitter (5) can directly embody the gas temperature after the compression.Gas pressurized is after safety check (6) prevents its backflow, [annotate: by air-cooled aftercooler (7) cooled gas again because the viscosity of liquid generally reduces with the increase of temperature, help its conveying so be heated to certain temperature to liquid, yet the viscosity of gas generally reduces with the reduction of temperature, therefore the overheated gas after the cooled compressed helps its line transportation], enter knock out drum (9) after removing impurity in the gas by oil removal filter (8), flow through ball valve (10) and prepare to enter main line.
After gas compressed by compressor (11), pressure gauge (13) and pressure transmitter (12) can directly embody the gas pressure after the compression, and thermometer (14) and temperature transmitter (15) can directly embody the gas temperature after the compression.Gas pressurized is after safety check (16) prevents its backflow, again by air-cooled aftercooler (17) cooled gas, enters knock out drum (19) after removing impurity in the gas by oil removal filter (18), flows through ball valve (20) and prepares to enter main line.
Two compressors (1) and (11) can in parallel be used, and also can one work independently.
Pressurized gas is by behind the ball valve (21), through filter (22) and by direct flow through the pressure difference before and after the filter (22) of measurement gas of differential pressure indicator (23), this moment is by flowmeter (24) metering gas flow, after flowing through mortor operated valve (25), pressure gauge (27) and pressure transmitter (26) can directly be read and enter the preceding gas pressure of simulation pipeline, thermometer (28) and temperature transmitter (29) can directly be read and enter the gas temperature of simulation before the pipeline, and gas enters the simulative tube road the superiors after by ball valve (30).
After the circuit the superiors carry, flow into second layer pipeline by ball valve (31).
After second layer line transportation; enter the 3rd layer of pipeline by ball valve (32); gas enters measuring room at the 3rd layer of pipe end; close ball valve (51) this moment; temperature transmitter (33) and thermometer (34) can directly be read gas temperature this moment; pressure gauge (35) and pressure transmitter (36) can directly be read the gas pressure of this moment; after flowing through ball valve (37); through flow through after filter (38) filtration and differential pressure indicator (39) test pressure differential ball valve (40) and flowmeter (41); behind the metered flow; measure its pressure with pressure gauge (42); safety cut-off valve through having protective function (43) and pressure governor (44) carry out pressure regulation again; flow through mortor operated valve (46) after measuring its pressure once more with pressure gauge (45), by pressure transmitter (47); pressure gauge (48); thermometer (49) and temperature transmitter (50) are measured each parameter of this moment.Be divided into two branch lines behind each parametric measurement of gas, can simulate pipe end gas storage and peak-shaving technology and gas holder gas storage and peak-shaving technology respectively.
Pipe end gas storage and peak-shaving technology:
When gas consumption descended and is lower than air demand, the gas reserves in the pipeline increased, and density increases, and manifold pressure is risen; During when the gas consumption rising and greater than air demand, the rock gas storage in the pipeline reduces, and density reduces, and pipeline pressure is descended.Therefore, long distance pipeline has certain gas storage and peak-shaving ability.
Close ball valve (52) and (64); gas storage during simulation gas consumption ebb; compressor this moment (1) and (11) works on; the simulation gas transmission is joined the station constantly to user's transport gas; gas pressure constantly increases in the pipeline; observe and write down the pressure tabular value of each diverse location; when pressure reaches setting value; open ball valve (64); gas flows into gas holder (68); ventilate to the user during simulation gas consumption peak, read its force value by pressure gauge (65) and pressure transmitter (66) this moment, and by safety valve (67) protection of being responsible for releasing.According to the different regions of being simulated, the uneven factor of monthly consumption value of different cities is adjusted corresponding pressure set points, thereby the pipe end gas storage and peak-shaving technology of this area or this city supply and demand amount is satisfied in simulation.
Gas holder gas storage and peak-shaving technology:
Though the gas pipeline gas storage and peak-shaving is economy but also convenient not only, piping volume is limited after all, so in order to satisfy the equilibrium of supply and demand, when most of and gas holder gas storage and peak-shaving technology common application.
Close ball valve (64); open ball valve (52) and (53); gas constantly flows in the gas holder (54); gas holder (54) internal pressure constantly raises; the gas storage of simulated high-pressure gas holder; measure gas holder interior gas pressure by pressure gauge (55) and pressure transmitter (56) this moment, safety valve (57) protection of being responsible for releasing.When gas pressure reaches setting value in the gas holder (54); close ball valve (53); shut down compressor (1) and (11); after treating that gas holder (54) internal pressure is stable; slowly open ball valve (58) and (59), pressurized gas flow in the gas holder (60), ventilate to the user during simulation gas consumption peak; this moment, pressure gauge (61) and pressure transmitter (62) were measured the interior force value of gas holder (60), safety valve (63) protection of being responsible for releasing.
Can realize the gas transmission state of different needs by the switch of unit and valve group.
For example: according to the size of displacement, can start compressor (1) or compressor (11) separately, realize unit group small flow working state, when two compressors are worked simultaneously, can realize big flow working state; Close ball valve (64) and (58), open ball valve (52) and (53), carry out the gas holder high-pressure gas, when gas pressure reaches setting value in the jar, close ball valve (52), at this moment compressor bank works on, and gas pressure reaches setting value in pipeline, open ball valve (64) and (52) this moment, and gas holder (68) is realized pipe end gas storage and peak-shaving technology and gas holder gas storage and peak-shaving technology simultaneously; Equally, close ball valve (52), open ball valve (64), when gas pressure reaches setting value in gas holder (68) and the pipeline, open ball valve (52) and (53), gas holder (54) is realized pipe end gas storage and peak-shaving technology and gas holder gas storage and peak-shaving technology simultaneously, when gas holder (54) when internal pressure reaches setting value, also can open ball valve (58) and (59), thereby realize single source of the gas multi-user feed status.
