The present invention provides the apparatus for decreasing PFC and generating tin fluoride, comprising: a reaction part having liquid tin (Sn) accommodated therein; and a material injection part for injecting PFCs into the reaction part, wherein the PFCs and the liquid tin react so as to generate tin fluoride (SnF2) in the reaction part.

Description

technical field [0001] The present invention relates to an apparatus and method for reducing perfluorinated compounds and generating tin fluoride, and more particularly, relates to a device and method for reducing perfluorinated compounds as a greenhouse gas while generating tin fluoride as a high value-added substance. Apparatus and method for perfluorinated compounds and generation of tin fluoride. Background technique [0002] Perfluorinated compounds are gases that cause global warming, and sulfur hexafluoride (SF6) is a representative example. [0003] Sulfur hexafluoride is a stable gas that is chemically inert. It is widely used in large-capacity power equipment or liquid crystal panels and semiconductors due to its excellent dielectric strength, fast dielectric recovery, and stable arc (Arc). [0004] However, it is known that sulfur hexafluoride cannot be quickly removed in the earth's atmosphere due to its strong infrared absorption ability and chemical stability,...

Problems solved by technology

[0007] It is known that the most widely used technology is combustion technology, but in order to remove perfluorinated compounds by combustion technology, it is necessary to maintain the thermal decomposition temperature of each target substance (NF 3 800 degrees, SF 6 1200 degrees, CF 4 1600°C or higher), and even if the corresponding temperature conditions are reached, it cannot be 100% removed if there is a lack of proper mixing and thermal decomposition of the reactants required for subsequent reactions

That is, because the combustion technology consumes a lot of energy and lacks economy, the conditions for completely removing perfluorinated compounds are harsh, and it is difficult to reduce the NO generated during combustion X , CO

[0008] In addition, the catalyst technology has a very short catalyst replacement cycle, and the plasma technology is also difficult to maintain the continuity of operation due to frequent replacement of torch materials, which lacks economy

[0009] And, especially since the prior art only focuses on developing technology for removing perfluorinated compounds, it is costly and uneconomical to remove perfluorinated compounds
