Abstract

The invention relates to a sulfur hexafluoride separation and purification device and a purification method thereof, wherein, the purification device comprises a first separating container and a second separating container. The air inlet of the first separating container is connected with a sulfur hexafluoride source through a first compressor, and the air outlet of the first separating container is connected with the air inlet of the second separating container through a buffer container and a second compressor. A ninth on-off valve is arranged between the second compressor and the second separating container; the first on-off valve is arranged between the air outlet of the first separating container and the buffer container; the fluid outlet of the first separating container is connected with a liquid storage container through the second on-off valve, and the air outlet of the liquid storage container is connected with the air inlet of the buffer container through a third on-off valve; the air outlet of the buffer container is connected with the air inlet of the first compressor through a fourth on-off valve; the air outlet of the second separating container accesses to the atmosphere through a pressure reducing valve and a fifth on-off valve, and the fluid outlet of the second separating container is connected with the fluid inlet of the first separating container through a sixth on-off valve.

Description

technical field [0001] The invention relates to a device for separating and purifying sulfur hexafluoride gas, and at the same time, the invention also relates to a method for purifying sulfur hexafluoride based on the device for separating and purifying sulfur hexafluoride gas. Background technique [0002] Sulfur hexafluoride electrical equipment is increasing day by day in the current power grid. According to relevant domestic authoritative data and statistics, the total amount of sulfur hexafluoride gas used in the production of switch products in China is about 10,000 tons a year. The current maintenance cycle is calculated on the basis of 10 years, and one-tenth of the sulfur hexafluoride gas needs to be replaced every year. The annual replacement volume is about 1,000 tons, which is about 140,000 yuan per ton, and the average annual cost is about 140 million yuan. In addition, sulfur hexafluoride gas is also designated as a greenhouse gas by the United Nations Environ...
