Traditional method is, when purity analysis instrument detects that oxygen is defective, i.e. closes and gives vent to anger Valve, opens atmospheric valve simultaneously, by underproof for surge tank oxygen emptying.This method exists such as Lower deficiency, first is that oxygen emptying causes huge energy waste;Second is during emptying Consume substantial amounts of man-hour;3rd is to cause potential safety hazard.Therefore, the same of raw material is being wasted Time reduce again production efficiency.
The most universal technique is to extract defective oxygen from the outlet of oxygen surge tank to return to absorption Tower system processes again, owing to needing to block the defeated of the qualified oxygen of purity during processing Supply gas stream, after purity is up to standard, opens the delivery air of oxygen again.The most in process of production It cannot be guaranteed that the seriality that system is given vent to anger.
Summary of the invention
In view of drawbacks described above of the prior art or deficiency, it is desirable to provide a kind of efficient molecular sieve system Oxygen machine.
On the one hand a kind of efficient molecular sieve oxygenerator is provided, including: air inlet, with described The absorption tower system that air inlet connects, purity analysis instrument, gas recovery system, described purity Analyser is in parallel with described gas recovery system,
Described purity analysis instrument one end in parallel with described gas recovery system is connected to described absorption The gas outlet duct of tower system, the other end is connected to oxygen gas outlet;
It is also equipped with gas outlet control valve on the pipeline of described oxygen gas outlet.
The efficient molecular sieve oxygenerator that the present invention provides can releasing oxygen continuously, the most quickly, And the purity producing oxygen can be detected in time, oxygen inadequate for purity is carried out timely Reclaim, return tower weight and newly purify, it is ensured that produce the up to standard of oxygen purity, and can supply continuously Gas, further increases production efficiency while economizing on resources.
Accompanying drawing explanation
By reading retouching in detail with reference to made non-limiting example is made of the following drawings Stating, other features, purpose and advantage will become more apparent upon:
Fig. 1 is efficient molecular sieve oxygenerator structural representation in the embodiment of the present invention.
Detailed description of the invention
With embodiment, the application is described in further detail below in conjunction with the accompanying drawings.It is appreciated that , specific embodiment described herein is used only for explaining related invention, rather than to this Bright restriction.It also should be noted that, for the ease of describe, accompanying drawing illustrate only with The part that invention is relevant.
