Abstract
The invention relates to a method for adding carbonate into lead electrolyte to treat hydrofluoric acid. The lead electrolyte is lead silicofluoride obtained through reaction between industrial silicofluoric acid and lead oxide. The method comprises the following steps of (1) adding silica powder into the industrial silicofluoric acid, wherein the silica powder reacts with hydrofluoric acid to generate silicofluoride, so as to remove a part of the hydrofluoric acid; (2) adding a certain amount of carbonate, and adding the lead oxide after the hydrofluoric acid is removed. The method has the beneficial effects that the using amount of the lead oxide is reduced; the added carbonate is low in cost, so that the cost can be effectively lowered.
Description
Technical field
The present invention relates to chemical technology field, especially relate to a kind of method that adds processes of carbonate treatment hydrofluoric acid in lead electrolytic solution.
Background technology
Lead electrolytic solution of many uses, such as can be as the electrolyte of lead acid accumulator.Lead electrolytic solution obtains fluosilicic lead plumbate by industrial fluorosilicic acid and lead oxide reaction conventionally.React as follows:
H
2SiF
6+PbO->PbSiF
6+H
2O
In industrial fluorosilicic acid, hydrofluoric acid meeting and lead oxide reaction, consume lead oxide.Therefore industrial fluorosilicic acid needs to purify in the time making lead electrolytic solution, removes fluohydric acid content in industrial fluorosilicic acid.General hydrofluoric acid reaction needed adds a certain amount of Cab-O-sil, after exothermic reaction, generate silicofluoric acid, but can not thoroughly fully react completely in course of reaction, remaining hydrofluoric acid will react with lead oxide, owing to having consumed expensive lead oxide, cause production cost higher.
Summary of the invention
The present invention will address the above problem exactly, and a kind of method that adds processes of carbonate treatment hydrofluoric acid in lead electrolytic solution is provided.
The technical solution adopted for the present invention to solve the technical problems is:
In lead electrolytic solution, add a method for processes of carbonate treatment hydrofluoric acid, described lead electrolytic solution obtains fluosilicic lead plumbate by industrial fluorosilicic acid and lead oxide reaction, it is characterized in that, comprises the steps:
(1) in industrial fluorosilicic acid, add Cab-O-sil, Cab-O-sil and hydrofluoric acid reaction generate silicofluoric acid, thereby remove a part of hydrofluoric acid;
(2) add a certain amount of carbonate, add again lead oxide after removing hydrofluoric acid.
Further, described carbonate is calcium carbonate or calcium bicarbonate.
Operation principle of the present invention:
Old technique: industrial fluorosilicic acid-Jia Cab-O-sil-generation silicofluoric acid-Jia lead oxide-electrolyte;
New technology: industrial fluorosilicic acid-Jia Cab-O-sil-generation silicofluoric acid-Jia carbonate-Jia lead oxide-electrolyte.
Beneficial effect of the present invention: reduce the use amount of lead oxide, the carbonate adding is with low cost, can effectively reduce costs.
