Abstract

In order to improve the efficiency of sulfur hexafluoride gas recovery and purification, an optimization method of technical parameters for sulfur hexafluoride gas recovery and purification based on quantitative characteristic parameter analysis is proposed. Combined with the reaction temperature, concentration of sulfur hexafluoride gas, concentration of SF6 gas, NOx, CO and other sulfur hexafluoride gas, the technical index constrained programming model of sulfur hexafluoride gas recovery and purification was established by using the equivalent constraint and zero emission constraint analysis method. Combined with the experimental test analysis method, the entropy weight characteristic analysis model of sulfur hexafluoride gas recovery and purification was established, and the quantitative parameter analysis of sulfur hexafluoride gas recovery and purification was carried out by combining the comprehensive index parameter analysis. The entropy weight analysis technology is used to analyze the influence of different recovery and purification parameters on the concentration of sulfur hexafluoride gas, and a quantitative analysis model of sulfur hexafluoride gas emission concentration is established. According to quantitative characteristic parameter analysis and data fusion technology, the technical parameters of sulfur hexafluoride gas recovery and purification are optimized. The experimental results show that by optimizing the technical parameters of sulfur hexafluoride gas recovery and purification, the content of toxic substances in sulfur hexafluoride gas is reduced, the effective separation capacity of sulfur hexafluoride is improved, and the energy cost is reduced.
