Background technique
With the continuous development of power system device, sulfur hexafluoride gradually replaces insulating oil to become the insulation in power equipment
Medium, coming into operation for sulfur hexafluoride electrical equipment provide great function for device miniaturization, power supply reliability.But with six
Largely coming into operation for sulfur fluoride equipment, decomposes harmful subfluoride, the sulfide of generation under arcing, such as directly
It is discharged to atmosphere, pollutes the environment, damages human body, corrosion electrical equipment, how to handle sulfur hexafluoride gas also to related maintenance
Department brings problem.
Sulfur hexafluoride gas recyclable device can be recycled and be purified to sulfur hexafluoride gas, and it is low to eliminate nocuousness therein
Fluoride, sulfide, and recycled, it prevents from being directly discharged into atmosphere, guarantees the normal of network system power equipment to reach
Safe operation, the purpose for reducing pollution, support personnel's safety.Current sulfur hexafluoride gas recyclable device figure is huge, operates
Complicated, expensive, sulfur hexafluoride gas recycling when equipment being suitble to disintegrate, be not appropriate for generating during on-site test lacks
Measure sulfur hexafluoride tail gas, the technical conditions that this purpose research is recycled based on existing sulfur hexafluoride gas, by device miniaturization,
The tail gas of quick its discharge of reclaiming clean while on-site test instrument operates normally is not influenced.
Summary of the invention
Present invention aim to solve problem above, a kind of Portable sulphur hexafluoride tail gas recycle and purification dress are provided
It sets, structural volume is small, uses without external power supply, and it is easy to operate, preliminary purification can be carried out to the tail gas generated in detection process
And recycling, it is suitable for laboratory and on-site test process.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: a kind of Portable sulphur hexafluoride tail
Gas recycling and purification device, its main feature is that: the equipment interface 1 including connecting detection instrument gas outlet, equipment interface and surge tank 2
Connection, surge tank, which has, makes the differential pressure pick-up 3 of sulfur hexafluoride stability of flow, surge tank followed by can according to pressure into
The motorized needle valve 4 of row aperture control, in motorized needle valve followed by the moisture and the decomposition products such as sulfide in adsorbable gas
Adsorbent tank 5, adsorbent tank is connected to the import of compressor 7 by three-way magnetic valve 6, and the outlet of compressor is connected to liquefier 8,
Liquefier passes through check valve 9 again and cylinder interface 10 is connected to gas cylinder.
Present invention is generally directed to be a small amount of exhaust gas discharged in field instrumentation detection process, based on sulfur hexafluoride gas return
On the basis of the technical conditions of receipts, device miniaturization is quickly returned while guaranteeing the normal operation of on-site test instrument
Receive the tail gas of its discharge of purification.Structure of the invention is small in size, and direct current supply is used without external power supply, easy to operate, can be to inspection
The tail gas generated during surveying carries out preliminary purification and recycling, and does not influence the normal use of detecting instrument in removal process, can
Detection and laboratory applications at the scene.
Detailed description of the invention
Fig. 1 is structure of the invention schematic illustration.
In figure: 1, equipment interface；2, surge tank；3, differential pressure pick-up；4, motorized needle valve；5, adsorbent tank；6, it three is powered

Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, and preferred embodiment described herein is only used for
The description and interpretation present invention, is not intended to limit the present invention.
Embodiment:
As shown in Figure 1, a kind of Portable sulphur hexafluoride tail gas recycle and purification device, including equipment interface 1, surge tank 2,
Differential pressure pick-up 3, motorized needle valve 4, adsorbent tank 5, three-way magnetic valve 6, compressor 7, liquefier 8, check valve 9, cylinder interface
10。
1 connecting detection instrument gas outlet of equipment interface, equipment interface 1 are connect with surge tank 2, and the main function of surge tank is
The pressure change between import and compressor 7 is buffered, system is made to have the sufficient time to carry out speed regulating control, buffering to compressor 7
Tank 2 makes sulfur hexafluoride stability of flow with differential pressure pick-up 3, and avoiding, which influences on-site test instrument, operates normally, after surge tank
Motorized needle valve 4 can carry out aperture control according to pressure, moisture in the adsorbable gas of adsorbent tank 5 and sulfide thereafter etc.
Decomposition product, the sulfur hexafluoride gas after preliminary purification enters compressor 7 by three-way magnetic valve 6, by sulfur hexafluoride gas pressure
It is reduced to critical pressure and so that sulfur hexafluoride is become liquid by liquefier 8, gas cylinder is pressed by check valve 9 and cylinder interface 10,
Complete reclaiming clean.
Present invention is generally directed to be a small amount of exhaust gas discharged in field instrumentation detection process, based on sulfur hexafluoride gas return
On the basis of the technical conditions of receipts, equipment is done it is small, guarantee on-site test instrument normal operation while quickly recycle
Purify the tail gas of its discharge.It can be controlled to a vacuum pump using adapter, pipe-line system and control steel cylinder are vacuumized to exclude
Air, the size of inlet pressure is monitored using differential pressure pick-up, to control the valve degree of motorized needle valve unlatching, by compressor
The tolerance of air inlet carries out measurement control, guarantees the operating of compressor speed stabilizing, prevents surge tank pulsatile change, makes the device air inlet
Remain the working condition of normal pressure.Preliminary purification processing is carried out to tail gas using adsorbent, with compressor and liquefied gas by six
Sulfur fluoride gas is converted to liquid and is pressed into steel cylinder by check valve and cylinder interface, completes purification and removal process.
