Description
Technical field
This utility model is related to adsorption tower, especially a kind of adsorption tower reclaimed for electric power SF6 gases.
Background technology
Although pure SF6 is a kind of nontoxic and nonflammable gas of colorless and odorless, and SF6 gases are risen in power equipment
The effect of dielectric.But there is a small amount of water vapour in the air chamber of High Temperature High Pressure, meet equipment regular event and produce arcing
When electric discharge or abnormal shelf depreciation, SF6 can decompose, its analyte（HF and SO2, SOF2, SOF4, SO2F4 etc.）In have severe toxicity and strong
Corrosive substance, these materials can etching apparatus internal magnetic elements.Moisture can also produce condensate on its surface and be attached to
Insulating part surface, causes to prolong face flashover.Further decompose SF6, be thusly-formed vicious cycle.The insulating properties of SF6 are with
Drop.There is the SF6 of analyte, the body of people, nose, face, eyes can be produced injury and stimulated.Also, SF6 and HF are to the earth
Atmosphere also have very strong destruction.The reason for based on insulation, environmental protection, three aspect of personal safety, SF6 gases are reclaimed
And Regeneration Treatment is necessary.SF6 gases in absolutely not SF6 being switched are emitted along cable duct！
Electric power SF6 reclaims general using the group being made up of recovery vehicle, SF6 compressors, filter, four big equipment of vacuum pump
Close air filter.Filter on recovery vehicle includes dry filter and dust filter unit, and dry filter is mainly used in SF6
The filtration of gaseous material, such as SF4, HF, SO2F2, SOF2, SO2 and CF4 in middle moisture content and SF6 analytes；Reach moisture
Below 10ppm.Filter material is aluminium oxide and molecular sieve.Dust filter unit is mainly used in the dust of solid-state and decomposition in SF6 gases
The filtration of thing.For the dust of diameter >=1um, stop rate is 100%.Due to fore filter small volume in electric power SF6 gases,
Function is poor, and adsorption efficiency is not high, and after long-time use, the material which decomposes relatively will be a lot, depend recovery vehicle itself alone
Filter is difficult a gas and filters completely totally, it is impossible to which the purity for reaching gas recovery does not reach the purpose of regeneration reuse.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of adsorption tower reclaimed for electric power SF6 gases, energy
It is enough to carry out adsorption treatment before SF6 gases recovery vehicle is filtered to poisonous SF6 gases, and the device volume is little and adsorption capacity
Greatly, adsorption efficiency is high, does not easily cause the blocking of reclaimer gas circuit absorbent powder, air tight and easily change adsorbent.In addition, should
The use of device decreases absorption purification SF6 and processes the frequency that machine host changes adsorbent.
To solve above-mentioned technical problem, the technical scheme adopted by this utility model is：
A kind of adsorption tower reclaimed for electric power SF6 gases, including support, support are provided with cylinder, and cylinder is distinguished up and down
Gas outlet and air inlet are provided with, filtering net cylinder in cylinder, is provided with, XD adsorbents and absorption cage are provided with drainage screen, are adsorbed cage
Interior placement chitosan absorbent.
The cylinder bottom is provided with heater.
The absorption cage includes upper half tennis, lower half tennis, and upper half tennis, lower half tennis side are hinged, and opposite side leads to
Cross snap lock.
The upper half tennis, lower half tennis junction are provided with chain, and chain is vertically connected with filtering net cylinder by hook.
The cylinder is high 1.3 meters, 0.14 meter of diameter.
A kind of adsorption tower reclaimed for electric power SF6 gases of this utility model, with following technique effect：
1）, by SF6 recovery vehicles front end arrange adsorption tower, as adsorption tower weight, volume are smaller, conveniently can pacify
It is mounted on general SF6 absorption, freezing and equipment for purifying, so as to carry out prefilter, which reduces SF6 regeneration machine hosts and change
Adsorbent frequency.It is also convenient in addition putting into operation and exiting, reduction is reloaded the time, or landfill.
2）, by rustless steel steel mesh from lower to upper clad type absorption, performance of the adsorbent than horizontal positioned adsorb it is high, it is ensured that no
Absorption dead angle is stayed, so that electric power SF6 gas absorptions process more environmentally-friendly, economical, efficient, practical, HF, subfluoride are removed more
Thoroughly, regenerate SF6 more durable.
3）, by arranging heater, the noxious substance after absorption can be decomposed, reduces process to toxic gas.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is schematic diagram of the present utility model.
In figure：Support 1, cylinder 2, gas outlet 3, air inlet 4, filtering net cylinder 5, XD adsorbents 6 adsorb cage 7, heater
8.Upper half tennis 9, lower half tennis 10, chain 11.
Specific embodiment
As shown in figure 1, a kind of adsorption tower reclaimed for electric power SF6 gases, including support 1, support 1 are provided with cylinder 2,
2 upper end of cylinder is connected with end cap by flange, and lower end is connected with cylinder by end socket.Cylinder is respectively equipped with 3 He of gas outlet about 2
Air inlet 4, in order to control the air pressure of inside, portion is additionally provided with pressure gauge on the apparatus.Filtering net cylinder is provided with the cylinder 2
5, XD adsorbents 6 and absorption cage 7 are provided with drainage screen, in absorption cage 7, chitosan absorbent is placed, wherein, XD adsorbents
Be distributed in filtering net cylinder surrounding, absorption cage is distributed in filtering net cylinder along the centrage of axis, by fixed absorption with can
Dismountable adsorbs, and improves absorbability.The device adopts material carries out clad type absorption from lower to upper for stainless drainage screen,
Performance of the adsorbent adsorbs high than horizontal positioned, does not stay absorption dead angle.Inhaled by installing in the defecator before SF6 recovery vehicles
Attached cage, and surrounding arrange XD adsorbents, so as to carry out dual absorption, can extend SF6 recovery vehicle upper filters service life and
Number of times.
2 bottom of the cylinder is provided with heater 8.Analyte after absorption can effectively decompose Toxic after heater heating
Matter such as S2F10O, SO2F4, SO2F2 etc..
The absorption cage 7 includes upper half tennis 9, lower half tennis 10, and upper half tennis 9,10 side of lower half tennis are hinged, separately
