For family, typically by the way that high-purity liquid oxygen storage tank is arranged, high-purity liquid oxygen is vaporized into high purity oxygen gas and is used.
But there is of high cost, energy consumptions a variety of unfavorable factors such as to waste for this mode, at the same time, nitrogen-making device by
There was only nitrogen in product, the oxygen in raw air is then discharged as exhaust gas, and there is also greatly wastes.
Utility model content
The purpose of this utility model is to provide a kind of devices producing high pure oxygen, without Large Air Separation Devices, more flexibly
Prepare high pure oxygen product, play waste utilization, energy-saving effect, oxygen content range in the high pure oxygen product of acquisition
>=99.999%, even >=99.9999%, purity reaches national standard《GB/T14599 pure oxygens, high pure oxygen and ultrapure oxygen》In it is high-purity
The oxygen even standard of ultrapure oxygen.
In order to achieve the above object, the utility model provides the following technical solutions：
A kind of device producing high pure oxygen, including, ice chest；Nitrogen-making device is set in ice chest；Domethanizing column is set to ice chest
Interior, condenser is arranged in top, and tower body sets oxygen-rich fluid entrance, connect with nitrogen-making device by pipeline, tower top sets oxygen-bearing fluid and goes out
Mouthful, tower reactor sets methane rich fluid outlet；High-purity oxygen column is set in ice chest, and reboiler is arranged in tower reactor, and tower body sets oxygen-bearing fluid and enters
Mouthful, it is connected by pipeline and the outlet of demethanizer column overhead oxygen-bearing fluid, tower top sets nitrogen-containing fluid outlet, and tower reactor sets high pure oxygen fluid
Outlet, the high pure oxygen fluid outlet are the outlet of high-purity oxygen liquid and/or gas vent.
Further, the domethanizing column is packed tower, and theoretical cam curve is no less than 10 pieces.
Also, high-purity oxygen column is packed tower, theoretical cam curve is no less than 50 pieces.
Further, the methane rich fluid outlet of the domethanizing column tower reactor, the nitrogen-containing fluid outlet of high-purity oxygen column tower top are logical
Piping connection is crossed to nitrogen-making device.
It in the utility model, is kept the temperature using ice chest, the condenser refers to condense the hot fluid risen in tower
Generate the heat-exchange apparatus of the cold fluid declined；The reboiler refers to carry out in heating generation the cold fluid declined in tower
The heat-exchange apparatus of the hot fluid risen.
Using the utility model, can using the oxygen-enriched liquid air being usually discharged in nitrogen-making device as raw material, without
Large Air Separation Devices more flexibly prepare high pure oxygen product.
Compared with prior art, the utility model has the advantage that as follows：
Compared with conventionally employed Large Air Separation Devices prepare high pure oxygen byproduct, the utility model can in no Large Air Separation Devices and only
In the case of having nitrogen-making device, high pure oxygen product can be more flexibly prepared, equipment is simple, and floor space is small, has a wide range of application,
The purity of the high pure oxygen product obtained reaches national standard《GB/T14599 pure oxygens, high pure oxygen and ultrapure oxygen》In high pure oxygen it is even super
The standard of pure oxygen.
