SF6 gas recovery and treatment service

You may also have encountered the following problems!

The SF6 gas in the high-pressure equipment will inevitably be mixed with a small amount of impurities, such as water, air, mineral oil, dust and various low fluorine compounds, due to the manufacturing process of SF6 new gas and the use and maintenance process of the equipment. When the content of these impurities exceeds the national standards, it may cause equipment failure or insulation breakdown, which in serious cases will threaten the safe and reliable operation of the power grid, and even lead to serious safety accidents or large-scale power outage.

In recent years, with the rapid development of the power industry, the volume of SF6 gas-insulated electrical equipment is also increasing, especially the GIS combination electrical equipment continues to increase, the gas consumption rises sharply, many of the existing SF6 electrical equipment operating life has reached the overhaul period or close to the life period, maintenance work also gradually increased. SF6 gas as insulation and arc extinguishing electrical equipment, in the following three cases must be recovered or neutralized SF6 gas and decomposition, including maintenance of electrical equipment in operation; Deal with faulty electrical equipment; Scrap or replace electrical equipment. Therefore, if we do not pay attention to the recovery and recycling of SF6 gas during on-site disintegration and maintenance, and there are no corresponding technical specifications and measures to deal with these replaced gases, it is possible to lead to more SF6 gas being leaked into the atmosphere.

Although SF6 gas itself is non-toxic, it has an asphyxiating effect, its specific gravity is about five times that of air, and if there is a leak, it will be deposited in the low-lying area, draining the oxygen out of the space. If the staff work in these environments without taking protective measures, it is very easy to inhale a large amount of SF6 gas and cause hypoxia and suffocation. In addition, SF6 gas will decompose and produce some toxic low fluorine compounds under the action of arc, which will further react with electrode materials, water, oxygen, etc., to produce other toxic compounds. The main gaseous decomposition compounds are HF, SO2, S0F2, SO2F, SF4, H2S; Solid products are SIF4, ALF3, WF6, CUF2 and so on. These decomposition products mainly cause serious harm to the human respiratory system, but also threaten the safety of electrical equipment.

From the above simple analysis, it can be seen that with the wide application of SF6 electrical equipment in recent years, the gas in the SF6 gas insulation equipment that has been in operation for many years needs to be replaced in large quantities due to the increase of moisture, the increase of impurities, and the decline of arc extinguishing performance, otherwise the safe operation of the electrical equipment will be seriously affected, and the disposal problem of a large number of replaced SF6 gas needs to be urgently solved.

On the one hand, it will constitute the personal safety of power transportation inspection personnel who come into contact with SF6 gas (especially closed SF6 switching stations or buried substations, etc.).

On the other hand, it will seriously endanger the operation safety of the equipment, and also cause serious pollution of the surrounding environment and the atmosphere. Therefore, the used SF6 gas is recycled, and the recovered gas is purified, in order to be recycled. On the one hand, it can curb the direct emission of SF6 gas and protect the environment; On the other hand, it can turn waste into treasure and save the operation and maintenance cost of the power grid, which is a highlight of the circular economy of the power grid system, and the social and economic benefits are obvious.

Together with you to understand the current situation of SF6 recycling in China!

1. At present, there are many kinds and specifications of SF6 gas recovery inflators in China, and their implementation standards are not the same. In 2006, China implemented the standard GB/T 12022-2006 "Industrial sulfur hexafluoride", which requires the purity of sulfur hexafluoride gas after recycling to reach more than 99.9%. Some power supply enterprises are equipped with recycling and processing equipment, but most of the recycling equipment only has simple drying and particulate matter filtration processing functions, and the purification treatment effect is not good, so that the treated gas can not meet the requirements of China's recycling and recharging standards after detection.

2. The recovery, treatment and recycling of SF6 gas in China has not attracted enough attention, the on-site recovery, treatment and recharge process of SF6 gas used in electrical equipment has not been institutionalized, and the management and treatment of recovered gas has not been unified among all units, and there is no perfect unified management mechanism and mode. Therefore, it is urgent to improve and improve the recovery and treatment management of sulfur hexafluoride equipment.

3. With the increase of SF6 waste gas recovery storage, the problem of directly discharging SF6 waste gas into the atmosphere or only discharging it into the atmosphere through simple filtration and adsorption during equipment maintenance generally occurs. People do not have a deep understanding of the harm caused by SF6 gas to the environment, the consequences of direct emission of waste gas into the atmosphere, and the awareness of environmental protection is weak. In many cases, when the recovery equipment is poor, or the manager has just left, the operator chooses to discharge directly into the atmosphere in order to save time.

4. Recycling and processing, especially purification equipment, is expensive and bulky. At present, most of the SF6 treatment devices sold on the market can only be processed in the laboratory, and they have not been miniaturized, on-site, and easy to use, and on-site purification treatment equipment is often a single purification means, and the treated gas cannot meet the requirements of the national SF6 gas new gas standard.

5, because the SF6 recycling equipment on site is out of service most of the time, however, these equipment with electronic and mechanical components are not in operation for a period of time, and often do not work when really needed or problems occur soon after start-up.

6. The power operation department purchases SF6 recycling and processing devices by itself with high cost, low utilization rate, and low economic output value. In Western developed countries such as Switzerland, power maintenance personnel prefer to outsource or lease ways to solve these problems. Leave professional matters to professional personnel to do. In particular, industrial user units such as petrochemical and metallurgy, due to the infrequent maintenance work, recycling and processing equipment is often difficult to use for several years or even ten years, and the utilization rate is extremely low.

7. The power operation department does not have enough manpower to carry out recycling and processing work, or due to the needs of post transfer, relevant personnel need to be re-trained when carrying out work, and the efficiency of recycling and processing work is not high.

8, each switch factory in the provinces and regions to carry out SF6 electrical equipment installation, not because the recycling equipment is occupied by other sites, or because the distance from the factory to the equipment installation site is too far, resulting in high transportation costs and low efficiency.
