Description

A kind of air compressor machine nitrogen gas generating device
Technical field
This utility model relates to a kind of nitrogen gas generating device, especially relates to a kind of air compressor machine nitrogen gas generating device.
Background technology
The nitrogen gas generator of commercial type is essentially all use air separation by PSA nitrogen (abbreviation P.S.A at present Nitrogen processed) it is the gas separation of a kind of advanced person, with high-quality import carbon molecular sieve (CMS) as adsorbent, use Under room temperature, pressure-variable adsorption principle (PSA) separation air is produced highly purified nitrogen or uses electrocatalytic method to carry out sky Edema caused by disorder of QI from.The air compressor machine providing nitrogen is all to be installed in a casing, after long-play, produces substantial amounts of Heat, heat is deposited with in instrument box, air compressor machine can be caused aging, burn.If air compressor machine damages and will make Become the interruption of experiment, cause the waste of resource, the problems such as experimental data is inaccurate.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of air compressor machine is provided Nitrogen gas generating device.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of air compressor machine nitrogen gas generating device, including the air-compressor set being sequentially connected with, the first gas bomb, condenser, Dehydrater, for separating air and generate nitrogen oxygen separating unit and first cleaner unit of nitrogen, described dehydrater The port of export is also sequentially connected with the second cleaner unit and exsiccator;
During work, air-compressor set the condensed device of the high temperature air with moisture and dust impurities extracted out condenses to often Temperature, then after dehydrater removes moisture, it is divided into two-way, nitrogen oxygen separating unit of leading up to is discharged oxygen and generates height Pure nitrogen gas, then export after the first cleaner unit removes dust impurities, another road goes chalk dust removing miscellaneous through the second cleaner unit Matter is the most dried, exports as zero level air.
Described air-compressor set includes multiple air compressor machine being arranged in parallel, and the port of export at each air compressor machine is also equipped with One check valve.The setting of multiple air compressor machines side by side, even if so some air compressor machine burns etc. also due to aging Do not result in the interruption of experiment, thus cause the waste of resource and the problem such as experimental data is inaccurate.Check valve simultaneously Setting can effectively avoid influencing each other between each air compressor machine.
Described air-compressor set includes three air compressor machines being arranged in parallel.
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.
