First flow control also it is separately installed with at the entrance point of described nitrogen oxygen separating unit and the second cleaner unit
Valve and second flow control valve.
Described nitrogen oxygen separating unit includes the nitrogen oxygen separator of built-in nitrogen oxygen separation membrane and gives vent to anger with nitrogen oxygen separator
The second gas bomb that end connects, is provided with oxygen analyzer, the second described gas bomb at the port of export of this second gas bomb
The port of export be also connected with two pipelines, wherein one is the nitrogen stream being connected with the first cleaner unit, and another is for even
Connect the nitrogen circuit of the inlet end of nitrogen oxygen separator, described nitrogen stream and nitrogen circuit are equipped with one and open
Closing valve, described oxygen analyzer is all connected with control system with switch valve.By oxygen analyzer analysis from the second gas bomb
Oxygen concentration in the nitrogen discharged, and then extrapolate nitrogen gas purity, if nitrogen gas purity meets sets requirement, then nitrogen
Air-flow road is connected, and cuts off nitrogen circuit;If nitrogen gas purity is unsatisfactory for setting requirement, then nitrogen stream cuts off, nitrogen
Loop is connected, to avoid the nitrogen not conforming to concentration requirement that follow-up nitrogen is used the infringement etc. of device.
Described switch valve is electromagnetic switch valve.
A check valve it is also equipped with on pipeline between the inlet end of first flow control valve and nitrogen oxygen separator.This
Place's check valve can effectively be avoided from the inverse punching of nitrogen of nitrogen circuit backflow to assemblies such as dehydraters.
This utility model operationally, air-compressor set the high temperature air warp with the impurity such as moisture and dust extracted out
Condenser condenses to room temperature, then after dehydrater removes moisture, is divided into two-way, and nitrogen oxygen separating unit of leading up to is arranged
Go out oxygen and generate the high pure nitrogen setting purity, then exporting after the first cleaner unit removes dust impurities, another road
Remove dust impurities through the second cleaner unit the most dried, export as zero level air.
Compared with prior art, this utility model has the advantage that
(1) air-compressor set being made up of multiple low power air compressor machines is substituted existing single powerful sky
Press, and each low power air compressor machine all separates with check valve such that it is able to effective reduce because air compressor machine damages
And the impact on follow-up test caused;Additionally, the single sky of noise ratio of three actual generations of low power air compressor machine
Press is also low by about 15%.
(2) nitrogen oxygen separating unit uses oxygen analyzer detect the oxygen concentration of its exit gas, thus extrapolate
Nitrogen gas purity, and then control to export the purity of nitrogen by the switch of two electromagnetic switch valves again, so can protect
Demonstrate,prove the purity of the nitrogen exported from the first cleaner unit, effectively avoid causing because output nitrogen gas purity does not reaches requirement
The problem of the inaccurate grade of subsequent experimental data.
(3) first flow control valve and second flow control valve all can also be connected with control system, and by each
From the opening degree of valve control to respectively enter nitrogen oxygen separating unit from dehydrater air out and zero level is empty
The flow of gas output unit (i.e. second cleaner unit and exsiccator), particularly may be because of output when nitrogen oxygen separating unit
When nitrogen gas purity needs not backflow to purify, can reduce accordingly enter nitrogen oxygen separating unit new except water empty
Gas so that the more water air that removes exports as zero level air after treatment, thereby may be ensured that the length of whole system
Time continual Effec-tive Function.
