The air compressor is connected with an oil-water separator via a connecting pipeline, the oil-water separator is connected with a coalescence filter, a carbon filter is arranged between the coalescence filter and an air heater, another coalescence filter is arranged between the air heater and a membrane separator, and an enriched oxygen gas outlet and a nitrogen outlet are arranged on the membrane separator. Besides, the membrane separator is formed by parallelly connecting a plurality of membrane groups, and a temperature detector is arranged on the air heater. The nitrogen generating device utilizing the membrane separation nitrogen generating mechanism to generate nitrogen is simple in process, compact in product structure and is space-saving. As the air heater is provided with the temperature detector controlled by a micro-control unit to protect the heater, damages to the membrane groups caused by over-high temperature of inlet gas are avoided. As the membrane separator is formed by parallelly connecting a plurality of membrane groups, the nitrogen output of the system can be increased by adding the membrane groups, and the purity of nitrogen is convenient to be adjusted within a range ranging from 95% to 99.9% according to requirements of users.

Among the figure: V represents three-phase alternating-current supply, and AT is an oxygen cell, and FI is a flowmeter.
The specific embodiment
As shown in Figure 1, air compressor 1 of the present utility model is connected with oil water separator 2 by connecting line, oil water separator 2 is connected with coalescent filter for molten 3, be provided with carbon filter 8 between coalescing filter 3 and the air heater 4, also be provided with coalescing filter between air heater 4 and membrane separator 5, membrane separator 5 is provided with oxygen rich gas outlet 6 and nitrogen outlet 7.Membrane separator 5 adopts a plurality of film groups to be formed in parallel.Air heater 4 is provided with the Temperature Detector 9 by the micro-control unit controls.
Operation principle of the present utility model is to utilize film separation and nitrogen-making:
Film separation and nitrogen-making mechanism is that film has the characteristic of selectively penetrating and diffusion to some gas composition, and gas separates and the purpose of purifying to reach.
The film group is the hollow fiber membrane bundle that a stainless steel casing cylindraceous and PVC macromolecular material are made, and every bundle comprises up to a million doughnuts as tubular heat exchanger, so that separating area to greatest extent to be provided.About tens microns of every fibre diameter is thin as people's hairline.Compressed air is entered by an end of fiber-film bundle, and gas molecule at first in the contact of the high-pressure side of film, is absorption, dissolving, diffusion, precipitation, effusion under pressure then.Every kind of gas all contains different infiltration rates, and infiltration rates " soon " such as oxygen, carbon dioxide, water vapour are oozed out laterally by the inboard fibre wall of high pressure, are discharged by the other end of membrane module, thereby have realized the separation of oxygen, nitrogen in the air.The general intake air of separated nitrogen pressure ratio hangs down 5-15psig (0.3-1.0bar).
Workflow of the present utility model is as follows:
Through send into the air cushioning jar after air compressor 1 compression and filter by oil water separator 2 after enter coalescent filter for molten 3, the gas that filters by coalescent filter for molten 3 heats by entering the hot device 4 of air frame after carbon filter 8 filtrations again, for preventing the too high damage film of intake air temperature group, air heater 4 is provided with the Temperature Detector 9 by the micro-control unit controls, temperature by Temperature Detector 9 control heated air, gas after 4 heating of process air heater is again through entering membrane separator 5 behind the coalescing filter, finish the mask work of oxygen and nitrogen by membrane separator 5, discharge or store by oxygen rich gas outlet 6 and nitrogen outlet 7 respectively.
