Described PLC electrically connects with described gas recovery system, described gas outlet control valve, For controlling the duty of described gas recovery system, and the unlatching of described gas outlet control valve And closedown.
The efficient molecular sieve oxygenerator that this utility model embodiment provides can releasing oxygen continuously, The most quickly;The purity of the oxygen of purity analysis instrument detection simultaneously, when the purity of oxygen is less than specific During value, purity analysis instrument transmission low level is to PLC, and PLC is according to receiving Low level control gas outlet control valve close, oxygenerator now the most outwards carries oxygen, and And PLC controls gas recovery system and reclaims impure oxygen, by underproof for purity oxygen Gas is recycled in adsorption tower purify, and owing to the most outwards supplying, oxygenerator is in underload shape State, sheaf space very high purity on adsorption tower, reach 99.995% through experiment measurement, molecular sieve is inhaled Attached very capable, therefore return to the defective oxygen in adsorption tower by Fast Purification, come back to Surge tank neutralization buffer tank in recovery system remains defective oxygen mix, to improve oxygen Total purity, typically can recover supply through 2-3 cycle, and a cycle time is 150 Second, stop waste and the shortcoming of original system recovery service life length caused due to oxygen emptying, Save resource and improve efficiency;When the purity of oxygen is more than or equal to particular value, purity Analyser transmission high level is to PLC, and PLC is according to the low level control received Make QI KOU control valve to open, normally work, and control oxygen recovery system and just carrying out Normal oxygen output services.
Further, purity analysis instrument 2 two ends are separately installed with the first electromagnetic valve 11 and the second electricity Magnet valve 13.Purity analysis instrument needs the oxygen flowing out oxygenerator to carry out purity detecting by collection, Connect electromagnetic valve at purity analysis instrument two ends respectively and can control to pass in and out the oxygen of purity analysis instrument Amount, it is ensured that the accuracy of purity analysis instrument detection.
Further, gas recovery system includes: tubing, is connected with described tubing Surge tank 5, described tubing include parallel connection gas flow to pipeline and gas effuser road.
Further, gas flows to the first stop valve 7 and the first check valve that pipeline includes being connected 9, described gas flows out the second stop valve 8 and the second check valve 10, institute that pipeline includes being connected State the first check valve 9 and described second check valve 10 gas flow is contrary.This utility model is implemented Gas recovery system in example includes surge tank, wherein equipped with through processing the oxygen that will flow out Gas, the air inlet of surge tank is connected with tubing;Wherein gas piping is at oxygen purity not Carry out what gas recovery purified again during foot, therefore, on two branch roads in parallel in gas piping Being provided with check valve in opposite direction, a branch road air inlet, another branch road is inadequate by purity Oxygen recovery is in adsorption tower.
Further, one end that tubing is not connected with described surge tank 5 is provided with valve.
Further, gas recovery system be provided with the side of described surge tank be connected to described in go out QI KOU control valve and oxygen gas outlet 6.
Further, gas recovery system differs from and installs one end of described surge tank and be connected to absorption Tower system and air inlet.Efficient molecular sieve oxygenerator in this utility model embodiment is by installing gas Underproof for purity oxygen recovery is purified to absorption tower system by body recovery system again.
Wherein, efficient molecular sieve oxygenerator also includes: air inlet 1, with air inlet 1 The absorption tower system connected, purity analysis instrument 2, gas recovery system, purity analysis instrument 2 and gas Body recovery system is in parallel, and purity analysis instrument 2 one end in parallel with gas recovery system is connected to suction The gas outlet duct 12 of attached tower system, the other end is connected to oxygen gas outlet 6;Oxygen gas outlet Gas outlet control valve it is also equipped with on the pipeline of 6.
