After continuing one section of high temperature, start to be cooled to slightly above intake air temperature, blow it is cold after gas by B tank exhaust valve QF3 through muffler
Discharge；
(4) B tank blow it is cold it is complete after, close valve 17, QF3, open valve QF7, B tank is pressed, B pressure tank is gradually increasing
It is extremely identical as A tank；
(5) A tank and B tank exchange working condition, and A tank is regenerated, and B tank is adsorbed；Compressed air is passed through by air inlet
After fore filter, accurate filter, ultraprecise filter remove liquid grease and solid particle, inhaled into large capacity active carbon
After adnexa removes most of oil vapour, B tank is entered by valve 5 and QF2 and is adsorbed, vapor is adsorbed by B tank adsorbent
Afterwards, dry gas passes through accurate filter, post-filter, is discharged by gas outlet；While the work of B tank, pass through valve QF6
With muffler to A tank carry out pressure release, and repeat step (2)-(4) in heating, blow it is cold, press step.
Compared with prior art, the invention has the following beneficial effects:
Go out filter by fore filter, oil removing, ultraprecise filter eliminates liquid in unstripped gas at a lower temperature
Grease and solid particle；By large capacity active carbon adsorber oil vapour is removed, ensure that low temperature or absolutely oil-free lower with gas
Index, and sorbent life is extended, there is significant save the cost effect.Adsorbed at elevated pressures, low-pressure into
Row parsing carries out decompression regeneration, energy needed for thus greatly reducing adsorbent reactivation to adsorbent.It is carried out using finished product gas
Regeneration blow it is cold, and will blow cold air by muffler exclusion, to ensure that finished product gas dew point without drift.
