Remaining air then goes successively to first oxygen-enriched membrane component, and first oxygen-enriched membrane component both ends is made to form pressure difference, oxygen-enriched from richness
Oxygen exhaust passage enters the room, and exhaust gas then passes through the second control valve 62 and is discharged by exhaust gas exhausting duct, due to first oxygen permeable membrane group
Part is behind second oxygen-enriched membrane component, and the air inlet oxygen content of first oxygen-enriched membrane component is low compared with second oxygen-enriched membrane component, institute
With first oxygen-enriched membrane component, in contrast load is bigger, and the service life is shorter in actual use.Above structure passes through four electricity of switch
Magnet valve, to make system according to first state and the second state intermittent duty, to change the load of two oxygen-enriched membrane components, most
Reach the load for changing two oxygen-enriched membrane components of balance afterwards, keeps the service life of the two and replacement frequency identical, which can
Field is adjusted in gas componants such as air-conditioning, refrigerators to apply.Certainly, separation system can also be applied in oxygen-enriched combustion-supporting field.
As interchangeable embodiment, the first pipeline 51 and third pipeline 53 and influent stream road 10 are connected by the first valve
It connects, the second pipeline 52 and the 4th pipeline 54 are connect with waste stream road 20 by the second valve, and the first valve and the second valve are two
Position three-way valve is switched in two positions by the spool of two position three-way valve and realizes first state and the second state alternate run.
As interchangeable embodiment, influent stream road 10 and waste stream road 20 are movably arranged, and pass through mobile influent stream road 10
It is connected to waste stream road 20 with corresponding inlet and outlet and realizes first state and the second state alternate run.
It can be seen from the above description that the above embodiments of the invention realize following technical effect:
By change gas flow direction realize oxygen-enriched membrane component load it is adjustable, so as to so that each membrane module load
Equilibrium guarantees system run all right, reduces the replacement frequency of membrane module, extends the replacement cycle, which can apply
In multiple fields, it is especially applied to oxygen-enriched combustion-supporting and indoor gas constituent adjustment field, can guarantee essential attribute simultaneously
Promote the convenience used.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
