Fig. 1 is the structure diagram of the present apparatus；
Label in above-mentioned figure is：1, dust filter unit；2, air accumulator；3, cooling driers；4, pressure regulator valve；5, supercharger；6, it makes
Oxygen machine；7, regulating valve；8, compressed air hose.
Specific implementation mode
Below against attached drawing, by the description of the embodiment, each structure for example involved to the specific implementation mode of the present invention
The works such as mutual alignment and connection relation, the effect of each section and operation principle between the shape of part, construction, each section are further
Detailed description.
140 m3 of nitrogen of purity 99.99% is produced per hour according to nitrogen-making device to calculate, which discharges oxygen-enriched
Resolution gas reaches 500m3/h, and oxygen content reaches 26-28%, and the requirement of pressure 0.1MPa, oxygenerator 6 are compressed air >=540m3/h,
Inlet pressure 0.5MPa, oil-containing≤10mg/m3 only need so the parsing tolerance of dry coke quenching discharge can meet the requirement of oxygenerator 3
It pressure is increased to 0.5MPa to send to oxygenerator 6, pressure 0.5MPa can be increased to from 0.1MPa using supercharger 5.
As shown in Figure 1, entire recovery scheme is that the oxygen-enriched resolution gas that the equipment of making nitrogen comes out enters resolution gas recycling can, then
It is filtered to remove dust through FLF-12/8 dust filter units 1, purity is 26%-28%, yield is about the clean of 500Nm3/h to obtain
Net oxygen rich gas, output pressure are about 0.15MPa-0.2MPa, oil content≤0.001ppm, dustiness≤0.01 μm.
Above-mentioned gas, which is passed through, is mainly used for the balanced oxygen-enriched tail separated from nitrogen oxygen separating system in resolution gas air accumulator 2
Pressure, flow and the purity of gas ensure that pressure, flow and the purity of continuous supply oxygen rich gas are stablized.And it can be become by pressure
Device is sent to prevent recycling resolution gas oxygen rich gas to the unlatching of the acquisition control operated pneumatic valve of the discharge oxygen-enriched pressure signal of resolution gas
Adverse current and ensure that THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE is safe and stable, reliable operation, while discharging oxygen-enriched parsing atmospheric pressure less than pressing
When power transmitter pressure set points, thus it is ensured that be smoothly oxygenerator 6 for oxygen rich gas.
Oxygen pressure charging system is made of oxygen supercharger 5, one way stop peturn valve, pressure transmitter etc., from tail gas recycle tank, powder
The oxygen rich gas that dirt filter 1 comes out is pressurized to the required pressure 0.5MPa of oxygen processed by oxygen supercharger 5, send to oxygenerator
6。
In addition it is provided with two by-pass lines in such a system, one is the compression for being accessed before oxygen supercharger 5 decompression
Air, compressed air cool down in cooling driers 3, and pressure regulator valve 4 is opened in PLC circuit control, and the compression of 0.1 MPa is replenished in time
Air prevents the gas pressure into supercharger 5 from influencing compressor effect or damage machine less than 0.1 MPa；When air accumulator 2
When pressure is more than 0.15MPa, PLC circuit controls pressure regulator valve 4 and closes, and prevents the excessive normal operation for influencing equipment of pressure.Work as storage
When 2 pressure of gas tank is more than 0.15MPa, this 4 valve of pressure regulator valve is automatically closed, and prevents the excessive normal operation for influencing equipment of pressure.
After another by-pass line is located at supercharger 5, including compressed air hose 8 and regulating valve 7, the effect of this bypass are oxygen generating plant
During breaking down or overhauling period and the maintenance of supercharger 5, it is ensured that the normal gas supply for giving oxygenerator 6 is pressed when overhaul of the equipments
Contracting air hose 8 inputs compressed air into oxygenerator 6 and ensures that oxygenerator 6 normally supplies.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is used, or without changing
Other occasions are directly applied to by the design of the present invention and technical solution, within protection scope of the present invention.
