Description
Technical field
The present invention relates to electric power and chemical field, more particularly to a kind of sulfur hexafluoride gas electrostatic for power equipment to remove
Dirt moisture absorption filter.
Background technology
SF6 gases are popularized as existing selectable excellent insulating gas on a large scale in transformer, with
The explosive growth of GIS, HGIS, SF6 gas-break switch quantity, the dosage of SF6 gases are huge.But it is the existing SF6 that guarantees the profit
Gas generation business is mostly using traditional producing gas method：Fluorine caused by electrolysis is prepared with reaction of Salmon-Saxl under the high temperature, except six
Outside sulfur fluoride, the accessory substances such as a small amount of sulfur tetrafluoride (SF4) are also generated.Directly changed using simple substance sulphur and excessive gaseous fluorine
Reaction is closed to form；That is S+3F2 → SF6+Q（Release heat）Fluorine gas and melting sulfur reaction, are to protect the sulphur in reactor
Hold what is reacted under 85~105 DEG C of molten condition with the fluorine gas being passed through.Contain plurality of impurities in the crude product of synthesis, its is miscellaneous
The composition and content of matter have very big difference because of the influence of the factors such as the purity of raw material, the material of production equipment, process conditions,
Up to 5%., its composition has sulphur fluorine compounds to content of impurities, such as：S2F2, SF2, SF4, S2F1O etc.；Sulphur fluorine oxide is such as
The such as impurity such as HF, OF2, CF4, N2, the O2 brought into SOF2, SO2F2, SOF4, S2F10O etc. and raw material are if it is desired to use height
Press in electric equipment, need to purify the impurity in crude product, the SF6 gases after synthesis are also needed to by washing, alkali cleaning, pyrolysis（Go
Except ten fluorides of severe toxicity）, drying, absorption, freezing, a series of decontamination process such as distilation can just obtain purity and exist
Then more than 99.8% product is pressurizeed with compressor again, be filled with the steel cylinder for being cooled to -80 DEG C or so, deposit in liquid form
.
Filtering link in process of production, if it is desired to filter out below PM20 small solid impurity, it is necessary to more
Advanced filter or screen pack, but production efficiency is very low.To ensure higher production efficiency, filter or screen pack
With regard to using only filtering bulky grain or thicker screen pack, guarantee production efficiency is in existing factory and saves cost using rudimentary
Filter type.Standard GB/T/T 8905-2012《The guide for processing and measuring SF6 gas in power apparatus》In, it is only right
SF6 purity, gaseous impurity, moisture dispatch from the factory requirement, because filtering purification SF6 gas process and link are more, small solid
Granule foreign is easier to enter in finished product gas, to the not in place of each link processing quality supervision, also easily makes gaseous impurity and water
Divide into finished product gas and finally pour into Bottle ＆ Can.
The content of the invention
The technical problem to be solved in the present invention and the technical assignment proposed are prior art to be improved with being improved,
A kind of sulfur hexafluoride gas electrostatic precipitation moisture absorption filter for power equipment is provided, lifting filter effect at lower cost is
Purpose.Therefore, the present invention takes following technical scheme.
A kind of sulfur hexafluoride gas electrostatic precipitation moisture absorption filter for power equipment, including the filter that Open Side Down
Cylinder, the filter chassis for being connected to filter cylinder lower end, between described filter cylinder and filter chassis at sealing
Reason, the top center of described filter cylinder are provided with gas outlet, and the center on described filter chassis is provided with air inlet, described
Filter cylinder inside ecto-entad be arranged cartridge filter, absorbing cylinder and inlet cylinder successively, described cartridge filter, absorbing cylinder and enter
Open Side Down for inflator, and described inlet cylinder communicates with air inlet, the lower end of described inlet cylinder, absorbing cylinder and cartridge filter with
Filter chassis is detachably connected and encapsulation process, and filter interior is separated to form 4 mistakes by inlet cylinder, absorbing cylinder and cartridge filter
Filter position room, it is to enter gas storehouse, the absorption storehouse between absorbing cylinder and inlet cylinder, positioned at cartridge filter inside inlet cylinder respectively
Filtering cabin between absorbing cylinder, go out gas storehouse between filter cylinder and cartridge filter；Described absorbing cylinder, cartridge filter and
It is densely covered with the stomata passed through for gas on the barrel of inlet cylinder, the barrel of described inlet cylinder and cartridge filter is provided with multilayer
The other Electrostatic Absorption screen pack of medical grade；Polymer adsorption is filled with filtering cabin between described absorbing cylinder and cartridge filter
Agent.
SF6 gases enter in inlet cylinder through air inlet, quiet uniformly across multilayer medical rank by the stomata on inlet cylinder
Electro Sorb screen pack, medical rank Electrostatic Absorption screen pack are kept off larger solid particle using screen pack simple screening mode
Firmly, while using the Electrostatic Absorption function of screen pack less solid particle is adsorbed on filtering network fiber；SF6 gases warp is just
After step filtering, by the stomata on absorbing cylinder even into polymeric sorbent, the adsorption function of polymeric sorbent is utilized
By the moisture content in gas and trace sulfide absorption in adsorbent surface；The SF6 gases after 2 filterings are finally passed through into filtering again
Stomata on cylinder is uniformly through multilayer medical rank Electrostatic Absorption screen pack, for avoiding polymeric sorbent from leading in high velocity air
The caused minute solid particles that collide with each other are crossed down, the SF6 gases after filtering enter in gas storehouse, pass through pipeline by gas outlet
Into in power equipment, the filtration device structure is simple, and manufacturing cost is relatively low, and effectively improves the filtering effect of SF6 gases
Fruit, in addition, detachably connected mode is easy to the dismounting of the screen pack of filter interior and safeguarded more between filter chassis
Change.
As further improving and supplementing to above-mentioned technical proposal, present invention additionally comprises following additional technical feature.
It is to be threadedly coupled between described filter cylinder, absorbing cylinder and cartridge filter and filter chassis, and connects
Place is provided with seal washer.The sealing with seal washer is connected through a screw thread, is connected firmly, good sealing effect, with filter chassis
Between convenient disassembly.
