Abstract

The invention belongs to the technical field of aluminum oxide production processes, and particularly relates to a system for improving liquid caustic soda unloading efficiency. The system for improving the liquid caustic soda unloading efficiency comprises an industrial switch, a settlement system, an upper computer, a vehicle identification device, a PLC (Programmable Logic Controller), a card swiping machine, a caustic soda unloading tank liquid level measurement device, an online analysis device and an electric valve component; the industrial switch is connected respectively with the PLC,the settlement system, the upper computer and the vehicle identification device through lines; and the PLC is respectively connected with the card swiping machine, the alkali discharge tank liquid level measurement device, the online analysis device and the electric valve component through lines. According to the system for improving the liquid caustic soda unloading efficiency, the problem of lower liquid caustic soda unloading efficiency finally caused by no representativeness, long assay analysis time and large error of a sampling assay method is solved, the system can be widely applied torelated systems of various liquid caustic soda unloading.

Description

technical field [0001] The invention belongs to the technical field of alumina production technology, and in particular relates to a system for improving the unloading efficiency of liquid caustic soda. Background technique [0002] The invention relates to an alumina production process. Sodium hydroxide is usually called caustic soda, or caustic soda or caustic soda, and is used to treat bauxite. Bauxite contains alumina, which is the raw material for producing aluminum. Sodium hydroxide can be used to purify alumina from the ore. In the production process of alumina produced by Bayer method, the role of sodium hydroxide is to purify alumina from ore. The reaction equation is as follows: Al2O3+2NaOH+H2O=2Na[Al(OH)4] or Al2O3+2NaOH=2NaAlO2+H2O , so liquid caustic soda (sodium hydroxide) is one of the essential raw materials in alumina production. The determination of sodium hydroxide-methyl orange neutralization titration method is generally used in the liquid alkali test ...
