Two-Stage Recovery System and Process for Recovering Aluminum Fluoride from Tail Gas Condensate in an Aluminum Fluoride Production System

摘要

Abstract the present invention relates to a process consisting of two stages to recover the aluminum fluoride intensification of tail gas from the production of output aluminum fluoride includes the steps of: inputting the output intensity tail gas The product by the production system of aluminum fluoride to a penny buffer tank storage; subjecting the condensation product of an ass gas flow from the tank to separate the solid interface buffer tank for the liquid Wbalt To produce first and aluminum fluoride steelThe solutions are separated from each other; and sending the solution to the sedimentation tank sedimentation tank deposition, thereby producing a second means pure surplus aluminum fluoride solid precipitate in the sedimentation tank sedimentation tank; attribute Pure liquid overflow from the sedimentation tank. Sedimentation tank to aluminum fluoride production system.The present invention leads to recovery of aluminum fluoride backside deposition gas to output enough to undertake course consists of two stages, the output ass gas condensation and thus to quickly retrieve High voltage for workers at the same time due to frequent washing tank interface with flat bottom sedimentation tank sedimentation tank. .
