206, the 7th pneumatic operated valve 217 and the second pneumatic operated valve 204 are in the open state, remaining valve is closed.Compressed air is from total air inlet
Pipe 201, the second tracheae branch 205, left air inlet pipe 214 enter left adsorption tower 215, moisture and carbon dioxide in compressed air
It is preferentially adsorbed, then oxygen is also adsorbed, and nitrogen then seldom adsorbs.Nitrogen is enriched in the gas phase, and from left adsorption tower
215 tops are discharged and flow to device rear from total escape pipe 222, this process thus referred to as " is adsorbed ".In right adsorption tower 219,
Exhaust emissions is carried out, the oxygen of the absorption in Dissociative adsorption agent regenerates adsorbent.The higher tail gas of oxygen-rich concentration, stream
Enter to oxygen-enriched recyclable device 300.When the absorption of left adsorption tower 215 tends to saturation, the 4th pneumatic operated valve 207,221 and of the 8th pneumatic operated valve
First pneumatic operated valve 203 is in the open state, remaining valve is closed.Compressed air is from total inlet pipe 201, the second tracheae branch
205, right air inlet pipe 218 enters right adsorption tower 219, and nitrogen is discharged from right 219 top of adsorption tower and flows to from total escape pipe 222
Device rear；The tail gas of left adsorption tower 215 is flowed into oxygen-enriched recyclable device 300.
When left adsorption tower 215 is absorption, right adsorption tower 219 is parsed, and opens the first cut-off on the 5th tracheae branch 212
5th pneumatic operated valve 209 of valve 213, third tracheae branch 208, the nitrogen of high-purity is from the top and middle and lower part of left adsorption tower 215
Enter right adsorption tower 219.The nitrogen of high-purity in right adsorption tower 219 spreads from the top down or spreads from bottom to top, so that
Adsorbent nitrogen content in tower is uniform, stable gas pressure.Pressing most important purpose is two: first is that keeping two pressure towers consistent, being subtracted
Impact of the small molecular sieve in adsorption tower in switching；Second is that the adsorption tower that a part of object gas has just terminated from work is shifted
To in the raw tower just terminated, capacity is reduced, to improve the rate of recovery.
The oxygen-enriched recyclable device 300 includes the first recycling branch 301 and the second recycling branch 307；First recycling
The entrance of the entrance of branch 301 and the second recycling branch 307 is all connected with tail gas recycle pipe 224；On the first recycling branch 301

Oxygen purity reaches 28% or more, pressure 0.15-0.2MPa) when, the first recycling branch 301 is access, and the second recycling branch 307 is
It is closed circuit, after oxygen-enriched air is filtered by the buffering of oxygen-enriched surge tank 302 and oxygen-enriched dust fine filter 303, flow to postposition
Equipment, such as oxygen-enriched storage tank.When oxygen content in air lower (oxygen-enriched purity is lower than 28%, pressure 0.15-0.2MPa), first
Recycle branch 301 be it is closed circuit, second recycling branch 307 be access, the lower air of oxygen content pass through 308 outlet of muffler.When
Pressure is lower than 0.15MPa or is higher than 0.2MPa, and the second recycling branch 307 is access, and air passes through 308 outlet of muffler.Therefore,
The oxygen concentration and flow that this oxygen-enriched recyclable device 300 is collected into are relatively stable, have saved operating cost.
