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

Embodiment approach

[0048] The present invention will be described below with reference to the accompanying drawings. However, the present invention can be implemented in many different forms, and therefore is not limited to the embodiments described here. In addition, in order to clearly describe the present invention, parts irrelevant to the description in the drawings are omitted, and similar reference numerals are assigned to similar parts throughout the specification.

[0049] Throughout the specification, when it is mentioned that a certain part is connected (connected, contacted, combined) with other parts, this includes not only the case of "direct connection" but also the case of "indirect connection" with other parts interposed therebetween. And, unless there is a special record to the contrary, when it is mentioned that a certain part "includes" a certain constituent element, it means that other constituent elements are further included, and other constituent elements are not excluded....

Abstract

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. The present invention provides a device for reducing perfluorinated compounds and generating tin fluoride, which includes: a reaction part containing liquid tin (Sn); and a raw material input part for injecting perfluoro compounds into the reaction part ( PFC), wherein, in the reaction part, the perfluorinated compound reacts with the liquid tin to generate tin fluoride (SnF 2 ).

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,...
