Filtered after dry, through Carbon Molecular Sieve Membrane by nitrogen oxygen separating, realize the separation of nitrogen.Freeze drier volume ratio is larger, for a long time
Serious, the fault rate height of operating condition abrasion, is particularly easy to damage, easily nitrogen production process is adversely affected.
The content of the invention
The purpose of this utility model is to provide a kind of novel pure nitrogen gas generator, to solve setting for pure nitrogen gas production process
It is standby it is simple, safe efficient it is durable, do not allow the fragile technical problem such as with failure.
In order to realize foregoing invention purpose, the technical scheme that the utility model is used is as follows：
A kind of novel pure nitrogen gas generator, including pass sequentially through inlet end, air pump, air voltage-stablizer, the sky of pipeline connection
Air filter, membrane dryer, nitrogen separation device, nitrogen gas filters and nitrogen output end；The nitrogen output end and supply branch all the way
Road and the connection of another road nitrogen gas concn detection branch, the other end and the supply branch road other end of the nitrogen gas concn detection branch connect
Connect, or be directly connected to outdoor discharge pipe.
The data output end of the nitrogen table of the nitrogen gas concn detection branch is connected with circuit control unit, circuit control
The outer exhaust of the control end of unit magnetic valve respectively with membrane dryer output end, the magnetic valve of air output end of voltage stabilizer and air pump
The magnetic valve of pipeline connects and controls its work.
Advantage of the present utility model and good effect：Replace electronic by the air back-flushing technique of mechanical membrane dryer
Moisture in freeze drier technology, efficient removal air, and power supply is not needed, it can effectively meet the steady of nitrogen gas generator
Fixed work, volume reduces, life, the shutdown of nitrogen machine never again caused by cooling driers failure.

Embodiment
Concrete structure of the present utility model is shown in Figure 1.A kind of novel pure nitrogen gas generator, including pass sequentially through pipeline
The inlet end 1 of connection, air pump 2, air voltage-stablizer MV1, air cleaner 3,4, membrane dryer 5, nitrogen separation device 6, nitrogen filtering
Device 7 and nitrogen output end 8；The nitrogen output end 8 is connected with supply branch road and another road nitrogen gas concn detection branch all the way, institute
The other end for stating nitrogen gas concn detection branch is connected with the supply branch road other end, or is directly connected to outdoor discharge pipe.
The data output end of the nitrogen table of the nitrogen gas concn detection branch is connected with circuit control unit, circuit control
The drainpipe of the control end of unit magnetic valve respectively with membrane dryer output end, the magnetic valve of air output end of voltage stabilizer and air pump
The timing drainage valve on road connects and controls its work.The circuit control unit uses programmable controller (PLC).
Pressure gauge PG1 is terminated with air voltage-stablizer MV1 output.It is connected in the bottom of two-stage air cleaner
Hand valve MV2 and hand valve MV3.Air manometer PG2 is connected between membrane dryer and nitrogen separation device.In nitrogen separation device and nitrogen
Nitrogen pressure table PG3,0.001 micron air filter inlet end connection hand valve MV4 are connected between air filter.
Nitrogen gas concn detection branch is provided with hand valve MV6, flowmeter FE1 and nitrogen table.
Supply branch road is provided with hand valve MV7, flowmeter FE2 and check valve CV1.
NV1 in nitrogen separation device is needle-valve.
Nitrogen gas generator technological principle explanation of the present utility model：
Air pump first crosses air voltage-stablizer by air pressurized, after (SV1 magnetic valves are timing drainage valve) and passes into 1
Micron, the air filtering core filtering of 0.02 micron accuracy, gas enters back into membrane dryer, by the back-flushing technique of air by air
Moisture removal, enters nitrogen separation device by SV2 valves, isolates the nitrogen of high-purity, by 0.001 micron of filter element filtering, production
Raw gas is divided into two-way, quantitatively discharges discharged by nitrogen table Concentration Testing by FE1 flowmeters all the way, another road is through FE2
The gas of flowmeter detection output is to place with gas requirement.
