More Information
Summary:The utility model discloses a gas guiding device used for a reaction kiln and a system for preparing and purifying fluorine hydride. The gas guiding device used for the reaction kiln comprises an inlet pipeline, an outlet pipeline and a sulphuric acid conveying pipe, wherein the inlet pipeline and the outlet pipeline are in elbow connection; the sulphuric acid conveying pipe is introduced into the inlet pipeline, and is introduced to the tail end inside the inlet pipeline, and is arranged under the elbow joint of the inlet pipeline and the outlet pipeline; when the gas guiding device is used, the inlet pipeline is vertically arranged, and is communicated with the reaction kiln for preparing fluorine hydride gas, while the outlet pipeline is communicated with a pre-purification tower; after the gas guiding device used for the reaction kiln is used, the fluorine hydride gas in the gas guiding device is reversely and sufficiently contacted with sulphuric acid, dust particles and sulfur trioxide carried by the fl
