Description

Technical Field

[0001] This utility model belongs to the field of heavy alkali production technology, and in particular relates to a heavy alkali production device that improves carbonization conversion rate. Background Technology

[0002] The production of heavy alkali (sodium carbonate, Na₂CO₃) via carbonation is a core step in both the Solvay process (ammonia-soda process) and the Hou's combined alkali production process. The key to the carbonation reaction is passing carbon dioxide (CO₂) into a solution containing sodium ions, producing sodium bicarbonate (NaHCO₃) precipitate, which is then calcined to obtain sodium carbonate. The detailed process and reaction mechanism are as follows:

[0003] When CO2 is passed into an ammonia-water solution (NaCl + NH3 + H2O), NaHCO3 precipitate is formed. The chemical equation is as follows:

[0004] NaCl+NH3+H2O+CO2→NaHCO3↓+NH4Cl;

[0005] The reaction mechanism is as follows: ammoniation occurs first, NH3 dissolves in water to generate NH4OH, which increases the alkalinity of the solution and promotes the absorption of CO2; then carbonation occurs, CO2 reacts with NH4OH to generate (NH4)2CO3, which further reacts with NaCl to precipitate NaHCO3 crystals with low solubility.

[0006] Key factors affecting the carbonization reaction include the concentration of ammonia brine, the concentration and method of carbon dioxide introduction, and temperature control.

[0007] Existing heavy alkali production equipment often suffers from uneven feeding, affecting the carbonization conversion rate of heavy alkali. In addition, the slow heat conduction during heating affects the reaction process. In response to this, this application proposes a heavy alkali production device that improves the carbonization conversion rate. Utility Model Content
