Working principle of the present invention is as follows：
SF61 operation principle of gaseous environment monitor control system：SF6SF is used in gaseous environment monitor control system 16Gas
Infrared monitoring sensor 111 and sensitivity adjustment device 112 work together to detect indoor SF6The concentration of gas；It is described infrared
The infrared light of the infrared light that light emitting diode can emit, transmitting passes through indoor air, if containing SF in room air6Gas
Body, SF6Gas is 948cm in wave number-1The band part at place can absorb infrared light, and infrared energy is caused to generate decaying；Institute
The infrared signal after decaying can be received by stating infrared receiving diode, and send monitoring and controlling module 12 to；The monitoring
Control module 12 is cloud service monitoring system, the energy value size of the infrared optical attenuation detected can be converted into phase by analysis
The SF answered6Gas concentration simultaneously uploads in cloud service database, is conveniently operated personnel's remote monitoring；Simultaneously as indoor different
The SF of position6Gas concentration is different, and by the infrared energy that infrared light receiving diode receives is also different after decaying
, by the way that sensitivity adjustment device 112 is arranged, the infrared light of the different-energy received by infrared receiving diode can be believed
Monitoring and controlling module 12 is being sent to after number being adjusted to same levels, and accurate SF in room air is measured to convenient6Gas
Concentration.
2 operation principle of mixed gas purification system：The wind turbine being arranged at the air intake of the mixed gas purification system 2
41 can deliver the air to mixed gas purification system 2, and mixed gas purification system 2 is mainly as pretreatment system.First,
Air enters dust filter unit 22, can filter out dust and solid granulates in room air, prevent dust and solid granulates into
Enter compressor 42, destroys equipment；Then, air enters the progress compression condensation formation liquid water of compressor 42, is passed through separator
Large quantity of moisture in 21 i.e. separable air；Finally, air is absorbed and filter by molecular sieve 23 using the adsorption function of molecular sieve 23
The impurity such as decomposition product, moisture, mineral oil and toxic and harmful gas in air, avoid moisture, dust, particulate solid and
The performance and used life of venomous injurant confrontation membrane separation assemblies 312 impacts.
3 operation principle of mixed gas separation and recovery system：Gaseous mixture after mixed gas purification system 2 is pretreated
Body is passed through mixed gas separation and recovery system 3.First, compressor 42 is set in the air intake of refined filtration filter 311, contains SF6
The mixed gas of gas enters refined filtration filter 311 after carrying out compression condensation again by compressor 42, to remove mixed gas
Middle remainder particulate impurity and condensate liquid, then by the way that the electricity between the refined filtration filter 311 and membrane separation assemblies 312 is arranged
Heater 313 heats mixed gas so that after the mixed gas of compression condensation is able to maintain that progress at normal temperatures
Continuous operation；Then, mixed gas enter membrane separation assemblies 312 carry out mixed gas gas with various component detached；Logical
Due to SF when membrane separation component 3126The density of gas is larger and infiltration coefficient between main gas composition in air
The ratio between all be more than 3, therefore, SF6Gas is flowed out from the outlet of membrane separation assemblies 312, other gas compositions N in air2、O2、H2O
And H2It is flowed out Deng from 312 outside permeable wall of membrane separation assemblies, is emitted into outdoor；Finally, it exports and detaches by membrane separation assemblies 312
SF out6Gas drains back into collecting/storing module 32 into mixed gas after being compressed by compressor 42 and carries out compression storage.
312 operation principle of membrane separation assemblies：The membrane separation assemblies 312 are using hollow-fibre membrane to each in mixed gas
The selected area update strategy performance difference of component gas realizes separation, purification or concentration；Gas with various component is through hollow-fibre membrane
Permeance property depends on the size and shape of the gas molecule itself, the physics of molecule, chemical property, the physical chemistry of seperation film
The interaction relationship of property and infiltration component and seperation film, when predominant gas and the ratio between the gas permeability coefficient that need to detach are big
It can be detached when 3.During hollow-fibre membrane is as the use of seperation film, the separating degree parameter such as table 1 of predominant gas.
The separating degree parameter of predominant gas in 1 air of table
Predominant gas H as can be known from Table 12O、N2、H2And O2Deng with the SF that need to detach6The ratio between gas permeability coefficient is more than all 3,
Therefore, it is detached using hollow-fibre membrane as membrane separation assemblies 312, it can be by SF6Gas and air are detached, simultaneously
Due to SF6Gas is more than air, therefore SF in regular octahedron and density6Gas can be from the centre exit stream of membrane separation assemblies 312
Go out, and the main component of air is emitted into outdoor then from the outside permeable wall outflow of membrane separation assemblies 312.
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
Limitation, it is other it is any without departing from the spirit and principles of the present invention made by changes, modifications, substitutions, combinations, simplifications,
Equivalent substitute mode is should be, is included in protection scope of the present invention.
