Description
Technical field:
The utility model relates to a kind of gas concentration unit, relates to a kind of retracting device of sulfur hexafluoride gas or rather.
Background technology:
Sulfur hexafluoride (SF
6) gas is increasingly extensive in the High-Voltage Electrical Appliances Application for Field as a kind of good insulation and arc-extinguishing medium, sulfur hexafluoride voltage transformer, transformer, combination of gases electrical equipment have replaced traditional oil-break, oily current transformer, have obtained to apply faster.
Simultaneously, SF
6Gas also is a kind of greenhouse gases.In the Kyodo Protocol book of control global warming in 1997, SF
6Gas is listed in one of 6 kinds of greenhouse gases.Mainly be because SF
6Gas has sizable potential danger to greenhouse effects: a SF
6Molecule is CO to the influence of greenhouse effects
223500 times; SF
6Behind the gas discharging atmosphere, but in atmosphere about 3400 of stable existence.The gas of operation sulfur hexafluoride electrical equipment can make the staff directly in the face of SF after entering atmosphere
6The catabolite of gas, and SF
6The catabolite of gas is as HF, SO
2, SOF
2, SOF
4, SO
2F
4Deng having toxicity and corrosivity, the serious threat field personnel's is healthy.
At present, existing sulfur hexafluoride gas recovery vehicle on the domestic and international market, generally all in hundreds of thousands unit even more than 1,000,000 yuan, cost an arm and a leg and bulky heaviness, about 200 kilograms and more than, can not realize the tail gas behind the on-the-spot sulfur hexafluoride device measuring of transformer station is reclaimed, can not solve the sulfur hexafluoride gas emission problem after the test.
So far do not see small-sized recovery SF as yet
6Measure device for recovering tail gas.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of miniaturization, easy and simple to handle, energy-conserving and environment-protective is provided, is fit to the on-the-spot device that moves, can tentatively reclaim the sulfur hexafluoride tail gas of sulfur hexafluoride device context test back discharging.
The technical solution adopted in the utility model is such, comprise compressor, reclaim steel cylinder etc., it is characterized in that comprising and reclaim gas circuit and detect control module, described recovery gas circuit is connected together in series by gas buffer jar, threeway, aspiration pump, gs-oil separator, oilless (oil free) compressor, recovery steel cylinder, and another road of threeway connects oilless (oil free) compressor; Described detection control module comprises the flow monitoring module, starts module, pressure detecting module, the flow monitoring module connects the outlet of sulfur hexafluoride tester, start module and connect aspiration pump, the pressure detecting module is arranged on oilless (oil free) compressor and reclaims between the steel cylinder.
As shown from the above technical solution, the utlity model has following beneficial effect: the one, can be the SF that discharges after the on-the-spot test
6Gas storage has solved the shortcoming that sulfur hexafluoride gas enters air in the recovery steel cylinder of special use, reduce the discharging of greenhouse gases, and compliance with environmental protection requirements has good social benefit and ecological benefits.The 2nd, avoid the tester directly to contact SF
6Gas and catabolite thereof are as HF, SO
2, SOF
2, SOF
4, SO
2F
4Deng severe toxicity and strong corrosive material, the tester's that keeps the scene intact is healthy.The 3rd, the sulfur hexafluoride gas that is stored in the special-purpose recovery steel cylinder can also utilize by after handling again, and has improved SF
6The gas circulation utilization rate has good economic benefit.The 4th, volume is little, easy and simple to handle, and is simple in structure, is particularly suitable for on-the-spot moving and uses.
Description of drawings:
Accompanying drawing is a principle process schematic diagram of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
As shown in drawings, from on-the-spot sulfur hexafluoride equipment such as transformer station or laboratory SF
6The gas that gas apparatus comes out is through the sulfur hexafluoride tester, as SF
6Gas humidity tester or catabolite tester are measured the back and are discharged to the gas buffer jar by the gas outlet.The gas buffer jar is connected the gas outlet of sulfur hexafluoride tester with threeway.Threeway is divided into two-way with gas, and one the tunnel offers oilless (oil free) compressor as driving pressure, and the aspiration pump of leading up to reclaims and to enter gs-oil separator, with the Impurity removal in the gas that reclaims, then by oilless (oil free) compressor with the gas boosting that reclaims to reclaiming in the steel cylinder.
Described detection control module comprises the flow monitoring module, starts module, pressure detecting module, is used for controlling the running of whole system.The flow monitoring module connects on-the-spot sulfur hexafluoride equipment, starts module and connects aspiration pump, and the pressure detecting module is arranged on oilless (oil free) compressor and reclaims between the steel cylinder.Like this, the flow monitoring module detects the SF of sulfur hexafluoride tester outlet
6Gas flow passes to the detection control module, whether starts aspiration pump by starting module controls.The pressure detecting module detects the gas pressure that reclaims steel cylinder, and when the pressure that reclaims steel cylinder reached setting value, bottle was changed in prompting automatically.
Front end at described recovery steel cylinder also can be established a Pressure gauge, and video data returns the detection control module.
The utility model also can be provided with LCDs, dynamically shows pressure, the SF that reclaims steel cylinder
6The flow of gas.
