| titleOfInvention | Method for smoke desulphurization by utilizing dolomitic lime |
| abstract | The invention relates to a method for smoke desulphurization by utilizing dolomitic lime. Dolomitic lime is hydrolyzed and digested into lime cream; the lime cream reacts with a MgCl2 solution, so that Ca(OH)2 is converted into CaCl2 to enter a liquid phase, but Mg(OH)2 enters a solid phase, thus calcium-magnesium separation is realized; partial Mg(OH)2 filter cakes are blended and pulped to be sent into an adsorption unit to covert SO2 and SO3 into MgSO4 so as to achieve the purpose of desulphurization; the residual parts of Mg(OH)2 filter cakes are dried to obtain Mg(OH)2 or calcined to obtain MgO; a MgSO4 solution obtained by desulphurization reacts with a CaCl2 solution obtained by calcium-magnesium separation, thereby forming a CaSO4.2H2O precipitate and the MgCl2 solution so as to obtain CaSO4.1/2H2O building gypsum; and the MgCl2 solution and the dolomitic lime cream are subjected to calcium-magnesium separation. The method has the advantages of abundant and cheap raw material and quick process; and a byproduct has higher use value and market prospect, and zero emission of solid and waste water can be realized. |
