Abstract

The invention relates to equipment for recycling and purifying sulfur hexafluoride gas by virtue of a liftable rectifying tower. The equipment comprises a raw material gas inlet joint, a filtering-absorbing device, a compressor, a refrigerating unit, a first rectifying tower, a second rectifying tower, a hydraulic jacking device, a first tail gas processor, a second tail gas processor and a supercharger. The invention further discloses a method for recycling and purifying sulfur hexafluoride gas by virtue of the liftable rectifying tower. According to the equipment and the method, an SF6 wastegas purification and regeneration technique meet the fresh gas standard GB / T12022-2014 Sulphur Hexafluoride for Industrial Use, the development of SF6 waste gas regeneration technique equipment is promoted, the problems in the regeneration and repeated use of SF6 waste gas are solved, the utilization rate of SF6 gas is increased, the emission of SF6 gas is reduced, the development of green poweris promoted, and the equipment and the method have great economic and social benefits.

Description

technical field [0001] The invention belongs to SF 6 The field of gas purification and regeneration technology specifically relates to an equipment and method for recovering and purifying sulfur hexafluoride gas in a liftable rectification tower. Background technique [0002] Due to its high dielectric strength and stable chemical properties, SF6 gas has become the main insulation and arc-extinguishing medium for high-voltage switchgear. Devices, transformers, etc., gradually replace similar equipment with traditional insulating media due to their advantages such as good insulation performance, small footprint, safe and reliable operation. [0003] Sulfur hexafluoride gas (SF6) is one of the six greenhouse gases prohibited by the Kyoto Protocol, and it may decompose to produce some toxic and harmful gases. With the massive use of sulfur hexafluoride gas in the power grid and the increasing attention to environmental issues in my country in recent years, how to purify SF6 g...
