The SF6 gas in the high-pressure equipment will inevitably be mixed with a small amount of impurities, such as moisture, air, mineral oil, dust and various low-fluorine compounds, during the manufacturing process of SF6 fresh gas and the use and maintenance of the equipment. When the content of these impurities exceeds the national standard, it may cause equipment failure or insulation breakdown. In severe cases, it will threaten the safe and reliable operation of the power grid, and even lead to serious safety accidents or large-scale power outages.
In recent years, with the rapid development of the power industry, the commissioning of SF6 gas-insulated electrical equipment is also increasing, especially the increasing number of GIS combined electrical appliances, the consumption of gas has risen sharply, and the operation of many existing SF6 electrical equipment has also increased. The years have reached the overhaul period or approaching the life period, and the maintenance work has gradually increased. SF6 gas is used as electrical equipment for insulation and arc extinguishing. In the following three cases, the SF6 gas and its decomposition products must be recovered or neutralized, including maintenance of electrical equipment in operation; treatment of faulty electrical equipment; scrapping Eliminated or replaced electrical equipment. Therefore, if we do not pay attention to the recovery and recycling of SF6 gas during on-site dismantling and maintenance, and do not have corresponding technical specifications and measures to deal with these replaced gases, then more SF6 gas may be leaked and discharged into the atmosphere. .
Although SF6 gas itself is non-toxic, it has a suffocating effect. Its specific gravity is about five times that of air. If a leak occurs, it will be deposited in low-lying places, expelling the oxygen in the space. If workers work in these environments without taking protective measures, they are very likely to inhale a large amount of SF6 gas and cause hypoxia and suffocation. In addition, under the action of the arc, SF6 gas will decompose to generate some toxic low-fluorine compounds, and these decomposed products will further react with electrode materials, moisture, oxygen, etc. to generate other toxic compounds. The main gaseous decomposition products are HF, SO2, SOF2, 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, and also threaten the safety of electrical equipment.
It can be seen from the above simple analysis that with the wide application of SF6 electrical equipment in recent years, the gas in the SF6 gas-insulated equipment that has been in operation for many years needs to be replaced in large quantities due to the increase of moisture and impurities, and the decrease of arc extinguishing performance. Affecting the safe operation of electrical equipment, the disposal of a large number of replaced SF6 gas needs to be solved urgently.On the one hand, it will constitute the personal safety of electric power 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 to the surrounding environment and the atmosphere. Therefore, the used SF6 gas is recovered and treated, and the recovered gas is purified, in order to be recycled. On the one hand, it can prevent the direct emission of SF6 gas and protect the environment; on the other hand, it can turn waste into treasure and save the cost of power grid operation and maintenance. It is a highlight of the circular economy of the power grid system, with obvious social and economic benefits.Let's take a look at the current situation of SF6 recycling in China with you!
1. At present, there are many types and specifications of existing SF6 gas recovery inflators in China, and their implementation standards are also different. In 2006, China implemented the standard GB/T 12022-2006 "Industrial Sulfur Hexafluoride", which requires that the purity of sulfur hexafluoride gas after recycling and processing must be above 99.9%. Some power supply companies are equipped with recycling and processing equipment, but most of the recycling equipment only has simple drying and particle filtering processing functions, and the purification treatment effect is not good, so that the treated gas cannot meet the requirements of China's recycling, recharging and reuse standards.
2. The recovery, treatment and recycling of SF6 gas in China has not received enough attention. The recovery, treatment and refilling process of SF6 gas used in electrical equipment has not been institutionalized on site, and the management and treatment of the recovered gas has not been carried out by each unit. Unification, there is no perfect unified management mechanism and model. Therefore, it is urgent to improve and improve the management of sulfur hexafluoride equipment recycling and treatment.
3. With the increase in the recovery and storage of SF6 waste gas, the problem of directly discharging SF6 waste gas into the atmosphere during equipment maintenance or just through simple filtration and adsorption is common. People do not have a deep understanding of the harm caused by SF6 gas to the environment, they do not know enough about the consequences of direct emission of waste gas into the atmosphere, and their awareness of environmental protection is weak. In many cases, when the recycling equipment is bad, or when the management personnel just leave, the operator chooses to discharge it directly into the atmosphere to save trouble.
4. Recycling, 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. However, the on-site purification treatment equipment often has a single purification method, and the treated gas cannot reach the national level. SF6 gas new gas standard requirements.
5. Since the on-site SF6 recycling and processing equipment is out of operation most of the time, however, these equipment with electronic and mechanical components have not been in operation for a period of time, and often fail to work well when they are really needed, or problems occur shortly after startup.
6. The cost of purchasing SF6 recycling and processing devices by the power operation department is high, the utilization rate is not high, and the economic output value is not high. In developed western countries such as Switzerland, electrical maintenance personnel prefer to solve these problems by outsourcing or leasing. Professional things are left to professional people to do. Especially in industrial user units such as petrochemical and metallurgy, due to infrequent maintenance work, recycling and processing equipment is often rarely used for several years or even last ten years, and the utilization rate is extremely low.
7. The electric power operation department does not have enough manpower to carry out the recycling and processing work, or due to the needs of job transfer, etc., the relevant personnel need to be re-trained when carrying out work, and the efficiency of recycling and processing work is not high.
8. When each switch factory installs SF6 electrical equipment in various provinces, it is either because the recycling equipment is occupied by other sites, or because the distance from the factory to the equipment installation site is too long, resulting in high transportation costs and low efficiency.
