| titleOfInvention | Method for preparing water glass by utilizing waste lead-containing glass and separating lead-containing compound |
| abstract | The invention relates to a method for preparing water glass by utilizing waste lead-containing glass and separating a lead-containing compound. The method comprises the following steps of: firstly, making the lead-containing glass of an abandoned cathode-ray tube (CRT) into water glass fusion cake, hydrolyzing the fusion cake, and separating hydrolysate to obtain a water glass solution; then adding an additive to convert lead dissolved in the water glass into lead sulphide, separating and collecting lead sulphide sediment to obtain a lead-free potassium or sodium water glass solution, further treating dissolved residue to convert the lead-containing compound in the residue into lead sulphide, and recycling lead sulphide in the hydrolysis residue by adopting a floatation method. The method disclosed by the invention has the advantages that silicon, potassium and sodium ingredients in the lead-containing glass of the abandoned CRT can be converted into the water glass, recycling of the lead-containing compound is solved; the water glass is a basic inorganic chemical industry product with wide application range; and recycling of the lead-containing compound is solved, the recycled lead-containing compound can be taken as a raw material for lead smelting, and recycling of lead resource is realized. |
