Abstract
The utility model relates to an SF6 gas recovery filtering unit used for the SF6 gas recovery in the electric equipment. The interior of a sealed casing body is provided with a filter chamber for filling the adsorbent and two gas inlet and gas outlet. The utility model can adsorb the moisture and impurities in the SF6 gas and ensure reuse of the SF6 gas. The utility model has the advantages of simple structure, easy fabrication and convenient operation. The utility model can not only reduce economic loss but also avoid pollution caused by the SF6 gas discharge.
Description
The utility model belongs to SF in the electric installation
6Gas recovery is filtered the device that utilizes again.
Because SF
6The insulating property of gas are very good, have parameter height, stable performance, reliable advantage with its electric installation of manufacturing as insulating gas, are filled with SF thereby make
6The electric installation of gas (as high-voltage switch gear) becomes up-to-date technical equipment and receives an acclaim.Yet this electric installation long-time running is through the influence of multiple environment in each season, makes SF
6Gas no longer is so pure, and the water content and the impurity of accumulation have surpassed required standard, cause 1. destroying insulating property, and 2. 3. the etching apparatus part produces pollution and toxic hazard.As everyone knows, SF
6Gas is met water can decompose generation HF and H

4Deng deep-etching and highly toxic substance, its consequence is hardly imaginable.This class electric installation belongs to the periodic replacement class abroad, is reclaimed by manufacturer and handles; Owing to economy and the first-class effects limit of technology, can only accomplish periodic maintenance, and majority is with SF in maintenance in China
6Gaseous emission re-fills purified SF to atmosphere
6Gas not only causes very big financial loss (per kilogram SF
6More than 100 yuan of gas, the SF that electric installation is interior
6Tens kilograms at least of gases, kilograms up to a hundred at most), what is more important can't be saved atmospheric pollution.
The purpose of this utility model is a kind of SF of design
6The gas recovery filtration unit can reclaim at the scene and remove by filter SF
6Moisture content in the gas and impurity make SF
6Gas is pure and be reused.
The SF that the utility model is designed
6Being characterized as of gas recovery filtration unit, device is the housing of a sealing, there are two dividing plates that the enclosure interior space is divided into three cavitys in it, two ends are the gas backstreaming chamber, middle have gas to pass through the hole for being filled with the filtration chamber of sorbent material on the dividing plate, gas is passed through, can not allow again sorbent material by and be fixed in the filtration chamber, the gas inlet-outlet with exterior is arranged two gas backstreaming chambers; Electric heater is equipped with in the position of the filtration chamber, bottom of this device, and the thermometer that can react filtration chamber's temperature is arranged on the device, and at least one end in device two ends has the lid that can open; The filtration chamber can be the independent parts intravital middle parts of shell of packing into, and it is more convenient to change sorbent material like this.
Accompanying drawing 1 is a Figure of abstract also, is the designed SF of the utility model
6The structural representation of gas recovery filtration unit.1 is device case among the figure, and 2 is dividing plate, and 3 is sorbent material, and 4 is thermometer, and 5 is the gangway, and 6 is electric heater, and 7 is end cap.The designed SF of the utility model
6A gangway connection of gas recovery filtration unit is filled with SF
6The electric installation of gas, another gangway are connected to gas recovery machine (compressor), and the recovery machine starts the back just can be SF in the electric installation
6Gas installs recovery after filtration, and gas deposits the cured article of bringing into through the gas backstreaming chamber earlier, is filtered through filter chamber again, and a part of moisture content and impurity are adsorbed agent and absorb, and gas is after another back cavity enters the recovery machine; After the electric installation maintenance was finished, the recovery machine was SF
6Gas more after filtration device charge in the electric installation, moisture content and impurity are adsorbed filtration once more in the gas, if moisture content and foreign matter content are higher, can filter several times repeatedly.The effect of electric heater is that acceleration moisture content and impurity are adsorbed.This device can regularly be opened end cap and change sorbent material and remove cured article impurity.The utlity model has advantages such as simple in structure, that making is easy, easy to use, can not only reduce financial loss, and avoid SF
6Gas enters the pollution that causes in the atmosphere, has reached the purpose of design requirement.
The designed filtration unit of the utility model can all adopt stainless steel to make, and sorbent material can be selected 5A molecular sieve (effective especially to absorption impurity) and Al for use
2O
3(effective especially to absorption moisture content) waits or mixes use.The contriver produces model machine by above-mentioned requirements and is used for test.Dress SF in the FX-22Dl type switch
6Gas 27Kg, water content 1482ppm reduces to 460ppm through twice filtration.Dress SF in the SFM-300T type switch
6Gas 150Kg, water content 50ppm, HF0.36ppm are through reducing to water content 3ppm, HF0.14ppm after twice filtration.Effect is very obvious.
Claims (3)
1, a kind of electric installation SF that is used for
6The SF of gas recovery
6The gas recovery filtration unit, it is characterized in that, device is the housing of a sealing, there are two dividing plates that the enclosure interior space is divided into three cavitys in it, two ends are the gas backstreaming chamber, and it is the filtration chamber that the space at middle part is filled with sorbent material, have gas to pass through the hole on the dividing plate, gas inlet-outlet with exterior is arranged two gas backstreaming chambers, and at least one end in device two ends has the end cap that can open.
