Embodiment
As shown in Figure 1, a kind of grid-connected load down of the oxygen of air separation plant and conveying transformation device, including the first oxygen space division processed
Tower 1, the second oxygen air separation column 2, the first oxygen compressor 3 and the second oxygen compressor 4 processed, in which: the oxygen making amount of the first oxygen air separation column 1 processed is
20000m3/h, the oxygen making amount of the second oxygen air separation column processed are 6000 m3/h.
The first oxygen air separation column processed is connect by the first conveyance conduit 5 with first oxygen compressor 3, the first oxygen space division processed
The oxygen that tower 1 produces inputs the pressurization of the first oxygen compressor 3 by the first conveyance conduit 5, and the second oxygen air separation column 2 processed passes through second
Conveyance conduit 6 is connect with second oxygen compressor 4, and the second oxygen air separation column 2 processed inputs the second oxygen compressor by the second conveyance conduit 6
4 pressurizations, are connected with helix tube 7 between first conveyance conduit 5 and the second conveyance conduit 6, by helix tube 7 by the first oxygen processed
Air separation column 1 and the low oxygen progress that the second oxygen air separation column 2 processed is produced are grid-connected, and the material of helix tube 7 is carbon steel pipe, model
It is relatively low using helix tube degradation economic cost for DN400.
The helix tube 7 is equipped with control valve 8.The switch and flow of 8 control valve of control valve.Control valve 8 is wafer type
Butterfly valve, the number of the wafer type butterfly valve are 2, and the control valve 8 is located at the both ends of the helix tube 7, close to helix tube 7 and
