Description
Technical Field
[0001] The utility model relates to the technical field of aluminum chloride preparation, in particular to a heating device for aluminum chloride preparation. Background Art
[0002] Aluminum chloride is an inorganic compound formed by chlorine and aluminum, and is a colorless transparent crystal or a light yellow crystalline powder. In industry, a common practice is to place an aluminum ingot in a closed heating device, heat it, and pass chlorine gas to perform a chlorination reaction. The generated aluminum chloride is produced and sublimated into a collector, and aluminum chloride particles are obtained after being captured. During use, some existing heating devices for preparing aluminum chloride first inject chlorine gas into the heating device and then pour aluminum liquid into it, so that the aluminum liquid can fully react with the chlorine gas. However, after the chlorine gas preparation reaction in the heating device is completed, chlorine gas needs to be sprayed inward through a chlorine gas pipeline for preparation operation. The directly sprayed chlorine gas may directly enter the collector with the reacted aluminum chloride, and sufficient contact between the chlorine gas and the aluminum liquid cannot be guaranteed, which is not conducive to the preparation effect of aluminum chloride.
