  • Purification system having pipelines arranged at different levels in height direction
    Patent number: 11426693
    Abstract: A purification system having pipelines arranged at different levels in a height direction is disclosed. The purification system can include: a first purifier and a second purifier disposed side by side symmetrically; an air input pipeline, an air output pipeline and a waste nitrogen input pipeline, wherein the air input pipeline, the air output pipeline and the waste nitrogen input pipeline are disposed at different heights, the gap between pairs of pipelines being determined so as to facilitate overhaul of three-stem valves, a value W being smaller than a value W when the air input pipeline, the air output pipeline and the waste nitrogen input pipeline are arranged in parallel on the ground, and the purification system further comprises: a three-stem valve platform formed by a framework structure in a number of levels, to facilitate overhaul of the three-stem valves.
