Bring certain economic benefit.
Detailed description of the invention
Brief description is made to content expressed by each attached drawing of this specification and the label in figure below:
Fig. 1 is the structure diagram of the present apparatus；
Label in above-mentioned figure is equal are as follows: 1, dust filter unit；2, air accumulator；3, cooling driers；4, pressure regulator valve；5, supercharger；
6, oxygenerator；7, regulating valve；8, compressed air hose.
Specific embodiment
Below against attached drawing, by the description of the embodiment, such as related to specific embodiment of the present utility model
The shape of each component, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle etc. make into
The detailed description of one step.
Produce 140 m3 of nitrogen of purity 99.99% per hour according to nitrogen-making device to calculate, which discharges oxygen-enriched
Resolution gas reaches 500m3/h, and oxygen content reaches 26-28%, pressure 0.1MPa, and the requirement of oxygenerator 6 is compressed air >=540m3/h,
Inlet pressure 0.5MPa, oil-containing≤10mg/m3 only need so the parsing tolerance of dry coke quenching discharge is able to satisfy the requirement of oxygenerator 3
It pressure is increased to 0.5MPa to send to oxygenerator 6, pressure can be increased to 0.5MPa from 0.1MPa using supercharger 5.
As shown in Figure 1, entire recovery scheme is, the oxygen-enriched resolution gas of the equipment of making nitrogen out enters resolution gas recycling can, then
It is filtered to remove dust through FLF-12/8 dust filter unit 1, so that obtaining purity as 26%-28%, yield is about the clean of 500Nm3/h
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 guarantee 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 guarantee that THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE is safe and stable, reliable operation, while discharging oxygen-enriched parsing atmospheric pressure lower 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 pressure 0.5MPa required for 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 that decompression is accessed before oxygen supercharger 5
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.
