2. raw air water removal is an important ring in flow, generally use cooling driers, but nitrogen dew point can only achieve-
20℃.Effectively to reduce the dew point of raw air, generally use air dryer, conventional drier is temp.-changing adsorption (TSA),
Its flow is complicated and increases energy consumption.Proposed in the A of Publication No. CN 105080288 Chinese invention patent application using three layers
Bed pressure swing adsorber, wherein in addition to using the nitrogen oxygen separating bed of one layer of carbon molecular sieve, add two layers of molecular sieve up and down and do
Drying prescription bed is dried, and nitrogen dew point is reached -60 DEG C.But although molecular sieve desiccant water absorbing capacity in PSA beds
By force, but circulating-heating must be used to regenerate, i.e. TSA " temp.-changing adsorption " flow could normally be used continuously, therefore be separated in oxygen, nitrogen
(PSA) pressure-variable adsorption under the conditions of be unable to alternating temperature, can not thoroughly regenerate makes drying effect substantially reduce；
3. in order to obtain High Purity Nitrogen, nitrogen processed is generally also adsorbed using stage variable pressure, uses two level individual layer bed pressure-variable adsorption more
Group series connection, twice separation absorption improve purity.Its flow complicates, and pipeline and valve are multiplied；Due to multistage purification and suction
It is attached, therefore its nitrogen making machine floor space is big, cost is larger, is not easy to skid and miniaturization.
