Dirt and sub-fraction water vapour, wherein most vapor will enter molecular sieve oxygen generator and hollow fiber membrane nitrogen device,
Of long duration will make two kinds of separators be in a kind of moist environment, seriously affect its separating property.Still further aspect its carry
Not fully, what air cannot be spontaneous enters in filter, it is necessary to preposition air compression plant or air pump etc. the scheme of confession.
Utility model content
The utility model the technical problem to be solved is that provide a kind of oxygen that can prepare certain purity and high
The air-separating plant of purity nitrogen gas, to solve drawbacks described above caused by the prior art.
In order to realize the purpose of this utility model, the utility model provides a kind of novel metallurgical oxygen and nitrogen separation device, bag
Oxygenous adsorbent equipment and nitrogen adsorption device, it is characterized in that：The nitrogen adsorption device include level-one nitrogen adsorption device and
Two level nitrogen adsorption device, the Oxygen Adsorption device are equipped with oxygen-enriched outlet and oxygen deprivation outlet, the level-one nitrogen adsorption device
Air inlet, rich nitrogen outlet and waste gas outlet, the oxygen deprivation outlet of the Oxygen Adsorption device are equipped with two level nitrogen adsorption device
It is connected with the air inlet of level-one nitrogen adsorption device, the outlet of rich nitrogen and the two level nitrogen adsorption of the level-one nitrogen adsorption device fill
The air inlet connection put, the air is before Oxygen Adsorption device is entered successively by air compressor, cooler, air water point
From device, air cushioning tank, filter, heater and gas flow regulating valve.
Preferably, the Oxygen Adsorption device is the molecular sieve oxygen generator of finished product.
Preferably, the level-one nitrogen adsorption device and two level nitrogen adsorption device are the built-in hollow cellulose of finished product
The device of film.
Preferably, the waste gas outlet of the level-one nitrogen adsorption device is connected with the waste gas outlet of two level nitrogen adsorption device
And it is exhausted directly in outside atmosphere.
Preferably, the moisture trap and filter bottom are equipped with liquid water discharge line.
The beneficial effects of the utility model are：Using air as resource separation oxygen and nitrogen, source cost is low, Er Qiequ
It is nexhaustible not to the utmost.Air after purification first passes around Oxygen Adsorption device, and the oxygen of higher degree is on the one hand made, another
Gas nitrogen content of aspect oxygen deprivation outlet discharge is higher, is substantially also a kind of nitrogen purification, and oxygen deprivation exports the gas of discharge
By nitrogen adsorption device twice, purity reaches more than 90%, is conducive under the high temperature conditions still have very as inert gas
Good antioxidation.In addition air compressor, cooler, moisture trap, air cushioning tank and mistake are first passed around in air
Filter can remove most of impurity and vapor in air, be conducive to subsequently obtain the nitrogen and oxygen of higher degree, and
Protect separator.Gas after purification is adjusted gas temperature to be separated to follow-up molecular sieve and adsorbed film by heater
Optimal temperature, improves purification effect.Gas flow regulating valve is added, can be made with steady air flow into later separation device
Air-flow is not in that separating effect caused by larger pressure differential is poor.
