轻质碳酸钙生产工艺技术改造若干问题的探讨

Abstract

Abstract: The improving technology for kiln gas purification system by using MP trays in the desulfurization tower and scrubber to increase the purification degree of kiln gas was put forward.By taking dynamic aging technology，lime milk became more delicate and uniform，so that the free alkali of the product was reduced and the product quality was improved.At the same time，a new technology of ‘three-in-one’ reactor was proposed，which can not only effectively improve the production capacity，but also saves the energy.

Key words: light calcium carbonate, MP tray, dynamic aging, free alkali, reactor
