Along with voltage levels SF6A large amount of installations of electrical equipment, to SF in electrical equipment6Gaseous mass supervision and management is also
Propose requirements at the higher level, mainly use SF6Gas decomposition product instrument, SF6Gas humidity instrument and SF6Gas purity instrument etc.
SF implemented by instrument6The quality surveillance work of electrical equipment.For guaranteeing apparatus measures accuracy, need the above-mentioned instrument of periodic check, existing
Verification mode is had to use distributing instrument to make gas to SF6Analyser verifies, and which exists two problems in practice: one is
The tail gas produced after verification is without purified treatment, and rear directly to airborne release by the road, verification tail gas is mainly composed of SF6Gas,
Also H is contained2S、SO2、SOF2、SO2F2Deng toxic gas, wherein SF6Gas is as greenhouse gases, and it is directly to air
Surrounding is brought bigger harm, its toxic gas contained to will also result in serious human injury after being sucked by people by discharge,
It is thus desirable to a kind of miniature tail gas clean-up reclaims verification tail gas technology；Two is that distributing instrument volume is relatively big, and needs and multiple steel cylinders
It is used together, can only be at labs SF6Analyser verifying work, SF in transformer station6The verifying work of analyser mainly leads to
Cross concentration known gas steel cylinder to SF6Analyser verifies, and first to steel cylinder evacuation during this gas steel cylinder fill, then injects gas,
Still remain partial air because of evacuation, cause oxidizable component in gas to react after entering steel cylinder, it is therefore desirable to one
Plant and be applicable to SF6The gas steel cylinder Canning Technique that analyser verification uses.
Existing SF6Gas purification recovery technology is used for SF in transformer station6The reclaiming clean work of gas in electrical equipment,
Because of SF6In electrical equipment, gas flow is more, for reaching the requirement that gas recovery efficiency is high, clean-up effect is excellent, SF6Gas purification
Retracting device design volume compared with big, comprise that components and parts are more, energy consumption is higher, be not suitable for heretofore described verification tail gas
Purify present situation；Also there is minority technology to use concentrated sulfuric acid solution or 0.1mol/L sodium hydroxide solution as absorbing liquid, absorb SF6
Poisonous and harmful element in gas, but this technology cannot absorb all toxic components, absorption efficiency in verification tail gas, adsorb every time
Before need to change the problems such as absorbing liquid, inapplicable verification tail gas clean-up present situation of the present invention.
Existing Canning Technique is currently mainly used in the fields such as packaging for foodstuff, city gas bottling and gas filling, wherein food
Packaging field is mainly the fill of the materials such as liquid beverage, and filling apparatus volume is relatively big, differs farther out with technology of the present invention；
City gas bottling and gas Canning Technique are used for pure gas or the fill of stable in properties gas, and technology of the present invention relates to
And mixed gas and gas the most oxidized, therefore, existing city gas bottling and gas Canning Technique are not suitable for institute of the present invention
State technology.

Sensor, each of which road purifies the 3rd electromagnetic valve, molecular sieve filter and the polymeric membrane filtration that gas circuit all includes being sequentially connected in series
Device, the input of two molecular sieve filters connects the outfan of the second diaphragm type compressor, two high scores respectively through the 3rd electromagnetic valve
The outfan of sub-film filter connects the input of returnable bottle.
Its operation principle is: when needs fill gas, first opens the first ball valve and the second ball valve and to gas bottle and prepares main gas circuit
Evacuation, then closes the first ball valve and the second ball valve, source of the gas is changed into SF6Gas, injects SF in bulking system6Gas,
Air in main gas circuit is prepared in dilution, is then shut off the connection of the first surge tank and source of the gas, opens the first ball valve and the second ball valve is taken out very
Sky, is replaced into SF the air prepared in main gas circuit6Gas, calculates residual air force value according to model 1When Time, then inject SF in gas circuit6Gas, the most several times, untilWhole process is by the first electricity
The configuration of gas in magnetic ratio adjusting valve and first, second ball valve control realization gas bottle.
WhereinFor residual air pressure, n is evacuation number of times, PnFor the vacuum measured, Q every timen-1For the gas measured every time
Bottle pressure value.Qn-1For the pressure recorded after steel cylinder for the first time inflation, P1The pressure recorded the most afterwards is taken out for first time steel cylinder.
When needs carry out Recovery Purifying to verification tail gas, source of the gas is changed into verification tail gas, by molecular sieve filter and macromolecule
Film filter cooperation carries out purified treatment to verification tail gas.
This utility model compared with prior art, has an advantage in that:
