The methanation compressor dry gas seals system of the present invention has the advantages that
One, former recirculated water enters water cooler water after circulating water as cooling medium, dry gas seals gas
Cooler tube side there will be incrustation scale blocking heat exchange pipeline, has a strong impact on heat transfer effect, and finally resulting in the moisture in gas can not be fine
Separation, eventually enter into dry gas seals system, by changing recirculated water into desalted water, can effectively prevent water cooler fouling, seal
Gas can well separate water into by water separator, effectively prevent water enter dry gas seals system ensure dry gas seals not by
Damage.
Two, original water separator inferior separating effect, add original water cooler for recirculated water, cooling effect is poor,
By original water separator is replaced by new water cooler, the water that water cooler cools down can be efficiently separated, effectively prevent water
Enter dry gas seals system and ensure that dry gas seals is not damaged by.Original blanket gas pipeline is increased steam jacket heat tracing, effectively
Ensure that blanket gas temperature does not declines, after being down to dew point at a temperature of preventing, water occurs, finally enter dry gas seals system.
Three, when normally producing, by controlling self-adjusting valve aperture, compressor dry gas seals pressure reduction can be effectively improved, anti-
Only cause because dry gas seals pressure reduction is low compressor to jump car, thus meet device 100% load operation.
