Abstract
The utility model relates to a gaseous filling and recovery unit solves and aerifys, retrieves and store needs of SF6 in the high-voltage electrical apparatus manufacturing and use such as 220KV and above voltage's high-voltage switch, transformer, condenser, improves gaseous gassing speed of filling. The main part has adopted a compressor unit and vacuum pump that its oil lubrication system and working gas keep apart, when guaranteeing that gas filling and recovery process are not polluted by oil, the gaseous speed of filling, the gassing speed that fills of SF6 improves 3 ~ 8 times respectively. The device is also characterized in that a self-regeneration refiner is adopted, and the adsorbent can be self-regenerated after being saturated, so that the operation process is reduced.
Description
The utility model is a kind of gas filling and recovering device, be specially adapted to high-tension electricity devices such as 220kV and above high-voltage switch gear, transformer, capacitor make or use in inflation, recovery and the storage of SF6, also can be used for other can, recovery and storages rare or noble gas.
The court had once applied for the utility model patent (CN86207843U) of gas filling and recovering device in 1986, by compressor, vacuum pump, chiller plant, heater, intermediate storage tank.Control valve and pipeline are formed, and the compressor of employing and the oil lubrication system of vacuum pump and gas circuit are isolated, and form no oil system gas filling and recovering device.The outstanding advantage of this device be guarantee gas in can and callback course not by oil pollution, obtain high-purity gas, it is thorough to reclaim gas, reduces the pollution of SF6 gas to environment.Deficiency is that the compressor air-discharging amount that adopts in the original device only is 10m
3/ h, air displacement is little, and it is slow to charge and discharge gas speed, vacuumizes for the SF6 electrical equipment of 220kV and above voltage, inflation, reclaims SF6 significant discomfort usefulness, does not satisfy user's requirement.But the maximum air displacement of the at present commercially available oilless compressor that can be used for this device is 10m
3/ h, no alternate device.In addition, after the sorbent in the filter in the original device reaches capacity, generally all to from filter, take out and put into baking oven and regenerate, what have just simply loads new sorbent again, the cycle that needs regeneration and change is short, increases operational formality, and it is not too convenient to use.
The purpose of this utility model is when guaranteeing that gas filling and callback course be not by oil pollution, strengthens the air displacement of system, improves the gas speed that charges and discharge, and the design sorbent can be from the device of regeneration, and formality simplifies the operation.
This no oil system can and recovering device are to form like this, and two compressors are linked up, and form a compressor bank and insert in the pipeline, and compressor can be oil-free lubrication piston compressor or diaphragm type compressor.
Use the aerating and exhaust device and original device comparison of compressor bank, very obvious effects arranged, as be used for SF6 electrical equipment production SF6 charge and discharge gas the time, under the same terms of initial pressure and end pressure, vacuum pumping rate is by original 1m
3/ h has brought up to 8m
3/ h, aeration speed is by 1 original～2m
3/ h has brought up to 5m
3/ h, recovery speed is by original 1m
3/ h has brought up to 3m
3/ h.
Its working principle is: after another compressor inserts, and the corresponding inlet pressure that improves original compressor, exhaust velocity increases, and air displacement increases.
This device also adopts the filter in the treater replacement original device of regenerating, and after sorbent is saturated, need not take out regeneration, has simplified operating process.
Fig. 1 is the fundamental diagram of this device.
Fig. 2 is the treater structural map of certainly regenerating.
Embodiment 1, this device is used for the inflation that vacuumizes of 220kV and above voltage SF6 electrical equipment, reclaims and store.
The following (see figure 1) of apparatus system principle
1, installing self vacuumizes
A, C interface sealing start vacuum pump 17 and drive valve 20,16,15,14,13,10,3, when reaching expection degree of vacuum, close whole valves earlier, shut down then.
2, storage tank vacuumizes
Connect C, D interface, start vacuum pump 17 and drive valve 7,16,13,10,3, reach expection degree of vacuum after, close all valves earlier, the left alone without help machine in back.
3, gas containers to be filled, or being full of gas containers to be recycled vacuumizes.
Connect A, B interface, open valve 16,18 and conventional vacuum pump 17, reach expection degree of vacuum after, first cut-off valve 16,18, the left alone without help machine in back.
4, inflation
Connect A, B and C, D interface, open valve 7,3,10,13,18, liquid in the high pressure tank 1 or gas are by heat exchanger 4, and treater 11 enters in the container to be inflated 19.
5, reclaim
Connect A, B and C, D interface.
(1) when the pressure of container 19 is higher than storage tank 1 pressure, drives valve 18,13,10,3,7, make the two pressure balance;
(2) close valve 10 after the pressure balance, drive valve 20 and compressor 8 reclaims, when container 19 internal pressures are lower than 0.2MPa, start compressor 9, and close valve 20 and proceed to reclaim, when container pressure is lower than 0.08MPa, open valve 15,14, and start oil-free vacuum pump 22, closing valve 13 simultaneously proceeds to reclaim, drive valve 16, observe vacuum measuring instrument 23, when container inner pressure is lower than 2kPa, close valve 16 earlier, 18, stop oil-free vacuum pump 22 again, and cut-off valve 15,14, next stop compressor 9 and 8 and close valve 7 successively.
In order to guarantee to reclaim gas purity, treater 11,21 is housed in this device, its structure is seen Fig. 2.Be filled with sorbent 31 in steel cylinder 32, the external belt having heaters 33 of steel cylinder is filled with thermal insulating material in the interlayer between shell 35 and steel cylinder 32, when sorbent reach saturated after, by logical treater power supply, under vacuum state, add heat-adsorbent and make it regeneration.
Claims (2)
1, a kind of gas filling and recovering device, by compressor, vacuum pump, heat exchanger, intermediate storage tank, treater, control valve and pipeline are formed, and its oil lubrication system of compressor and vacuum pump and its air-channel system are isolated, and it is characterized in that adopting two compressors to link pipeline.
2, gas filling as claimed in claim 1 and recovering device is characterized in that treater has the heater and the shell that can connect power supply by steel cylinder, steel cylinder outside and forms, and load sorbent in the steel cylinder, are filled with thermal insulating material in the interlayer between steel cylinder and the shell.
