The key equipment of the impurity such as moisture, carbon dioxide and hydrocarbon.Molecular sieve equipment utilizes two absorber cycle alternation works
Make, the normal cryogenic absorption purification of an absorber, the another regeneration of high temperature parsing simultaneously, to achieve the purpose that continuing purge air.
When absorber is in normal cryogenic absorption or blows the cold stage, the pipeline work that is connected is in 5 ~ 10 DEG C of normal worst cold cases；When absorber is cut
When changing to high-temperature heating and parsing regeneration, pipe operations temperature can rise to 180 ~ 200 DEG C.Molecular sieve adsorber switch operating,
Realize loop cycle, therefore the state of hot and cold alternation is also presented in the pipe operations temperature in system.
When absorber high temperature parses, pipeline need to be arranged heat preservation heat insulating construction and reduce heat waste and anti-scald protection；Normal low temperature is inhaled
Attached and when blowing cold, cold insulation heat insulating construction, which need to be arranged, in pipeline prevents outer surface from condensing.Since the hydrophobicity performance of inorganic heat insulation material is poor,
If single setting insulating layer, it be easy to cause in use process thermal insulation material water suction softening or swollen splits destruction.Similarly, hard is organic
The heat-resistant stable of material is poor, can not be 100 DEG C or more of the single setting organic material Cold-keeping Layer in workplace.
Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of cold and hot pipe insulations
Structure is not only able to satisfy heat preservation thermal protection and requires but also be able to satisfy cold insulation anti-condensation requirement, and the technology to solve existing adiabatic scheme is asked
