Abstract

The invention discloses an impurity removal process and device for a scintillation rotary-floating calcining furnace. The process comprises the following steps that materials calcined in the scintillation rotary-floating calcining furnace enter a high-temperature cyclone separator from an outlet of the scintillation rotary-floating calcining furnace to be subjected to gas-solid separation; gas separated by the high-temperature cyclone separator enters a preheating system; and materials separated by the high-temperature cyclone separator are conveyed to fluidization impurity removal equipment through a discharge valve. The method has the technical effects that impurities in the product can be more effectively removed, the purity of the product is improved, and the economic benefit is increased.

Description

Technical field [0001] The invention relates to the technical field of chemical impurity removal, specifically to a scintillation spin-flotation calciner impurity removal process, and also to a scintillation spin-flotation calciner impurity removal device. Background technology [0002] The current scintillation spin-flotation drying and calcining process has achieved very good results in calcining magnesium salts, calcium salts, dolomite, kaolin and other materials. It is a mature technology. The materials are fed into the drying system by the feeder and processed in the dryer. After dehydration and drying, the material is recycled through the drying cyclone separator and drying bag collector. The dried material enters the three-stage preheating system for preheating, and then enters the main calcining furnace of the flashing rotary flotation calcining furnace for calcining. The clinker is recovered by the high-temperature cyclone separator, and then enters the cooling cycl...
