The present application relates to a kind of production system for preparing calcium hydroxide with dry calcium carbide slag, including raw material impurity removal mechanism, calcium oxide digestion mechanism, precision grinding mechanism and drying mechanism in turn, the calcium oxide digestion mechanism is connected in turn with hydrolysis machine and digestion stirring tank, by hydrolysis tank and digestion stirring tank, the full hydrolysis digestion of calcium oxide is realized, hydrolysis tank is suitable for the full fusion of powder raw material and distilled water, the mode of powder is spouted by screw jet, avoid the phenomenon that the agglomeration of two mixtures in prior art appears and is not fully hydrolyzed, by the stirring of double helix structure, it can also realize transverse shear, avoid the small agglomeration of material appears again.The present application realizes efficient, low-cost, tail material utilization and environment-friendly production mode by constructing flow line type production system, and carries out scale production of calcium hydroxide with industrial tail material dry calcium carbide slag.

The application discloses a method for digesting and separating fluorinated aluminum by program, which comprises the following steps: placing a catalyst with metal elements supported on alumina as a carrier into a reaction container of a cluster digestion device, adding hydrochloric acid and / or nitric acid, setting a digestion program, introducing inert gas for pre-pressurization, performing primary digestion, and simultaneously starting a condensation reflux atomizer; after the program is completed, adding hydrofluoric acid, setting a digestion program, and performing secondary digestion; after the digestion is completed, entering a cooling and crystallization program, performing cooling and crystallization, and separating to obtain a sample solution to be detected and a solid; the solid is dried and calcined to obtain fluorinated aluminum crystals, and the liquid is used for detecting the content of metal elements. The method is applied to the digestion treatment of the alumina sample with metal elements supported thereon, has a large sample treatment range, complete digestion, no volatile loss of elements, and can separate AlF3 in an alpha crystal form through the program digestion of the digestion device.

The present application relates to a kind of sintered quicklime digestion control device, the control device includes digester system, sealing structure and dust removal system, the digester system includes three levels structure, from top to bottom in turn first-stage digester, second-stage digester and third-stage digester, sealing structure is set to the outside of digestion system, dust removal system is set to the top of entire device;The scheme realizes the digestion of quicklime, realizes the water intake of hydrated lime in whole process control, after passing through third-stage digester device, make quicklime fully digestion, and in quicklime digestion process, can be qualitatively judged quicklime quality by the reaction temperature after quantitative water supply, adjust the water supply in digester, and carry out sealing treatment to feed inlet and discharge port, utilize integrated dust removal system, respectively handle and return digester to dust and water vapor in digestion process, ensure 100% recovery.
