Specific implementation mode
As shown in Figure 1, in the preferred embodiment of the present invention, air separator of oxygenerator includes exhaust gas pretreatment system
System, waste gas adsorption system, exhaust gas desorption system, adsorbent bed cooling and drying system, desorption gas condenser system and control system, control
System controls for PLC program, is carried out automatically controlling to entire air separator of oxygenerator.Height boiling may be contained in organic exhaust gas
The organic matter of point, these high boiling organic matters can be blocked carbon fiber adsorption and catalytic combustion after the absorption of sorbing material activated carbon fibre
Micropore leads to the failure of sorbing material.Therefore, before organic exhaust gas enters waste gas adsorption system, first organic exhaust gas is allowed to pass through
Exhaust gas pretreatment system carries out coarse filtration pretreatment.There are 2 adsorption boxes in waste gas adsorption system, constitutes secondary absorption, organic waste
Gas is introduced into 1 adsorption box and carries out primary adsorption, enters back into another adsorption box later and carries out secondary absorption, to reach discharge
Standard.At least one absorber is designed in each adsorption box, absorber is equipped with sorbing material activated carbon fibre, organic exhaust gas
In organic solvent adsorbed by high performance active carbon fibrous material, purified clean gas emits.What is adsorbed is organic
(desorption) is desorbed by exhaust gas desorption system again in solvent, is desorbed from sorbing material by organic solvent by water vapour,
The mixed gas of the organic solvent and water vapour that desorb then is condensed into desorption gas condenser system, and gas condensed system is desorbed
System includes secondary condenser, wherein first order condenser is pipe bundle condenser, and second level condenser is spiral plate condenser, cold
Solvent after solidifying is recycled, and on-condensible gas therein returns again to waste gas adsorption system and adsorbed again.In exhaust gas desorption system
In, due to also remaining a large amount of moisture after each desorption in activated carbon fiber core, the presence of these moisture is not only occupied greatly
Amount of activated Carbon fibe micropore, and adsorption efficiency of the activated carbon fibre to organic molecule is seriously affected, cause balance saturation to be inhaled
Attached amount declines；In addition the suction of activated carbon fibre will be seriously affected generally at 100 DEG C or more by desorption or activated carbon fibre temperature
Attached efficiency, therefore after desorption, cooling is dried to activated carbon fibre with adsorbent bed cooling and drying system again in profit, it is ensured that
When next cycle adsorbs organic exhaust gas, adsorption bed temperature can be down to 40 DEG C hereinafter, ensureing its adsorption efficiency in a short time.
