摘要
SO是污染大气、危害健康、造成经济损失的主要污染气体,也是水泥窑等大型工业生产过程中排出的一种主要的废气,严重地影响着人们的生活.在目前的脱硫方法中,干法脱硫无废渣废水产生,热损耗低,有利于节能减排,是目前最环保的方法之一,众多干法脱硫剂中钙基脱硫剂因其资源丰富、使用简便占据重要地位.含钙工业废渣由于钙含量高或富含金属氧化物及SiO_(2)等成分,被用于钙基脱硫剂的制备与改性,提高干法脱硫性能.综述了含钙工业废渣制备和改性干法脱硫钙基脱硫剂的现有研究,并通过分析改性机理及脱硫反应过程,对提高含钙工业废渣脱硫性能的改性方法进行了讨论.
SOis the main pollution gas that pollutes the atmosphere, endangers health and causes economic losses. It is also one of the main exhaust gases discharged from cement kilns and other large-scale industrial production processes, which seriously affects our lives. In the current desulphurization method, dry desulphurization has no waste slag wastewater generation, low heat loss, is conducive to energy saving and emission reduction, and is the most environmentally friendly method at present. In many dry desulphurization agents, calcium-based desulphurization agent has an important position because of its rich resources, and easy to use. Calcium-containing industrial waste slag was used in the preparation and modification of calcium-based desulfurizer to improve dry desulfurization performance due to its high calcium content or rich metal oxides and SiO_(2). In this paper, the present research on the preparation of calcium-containing industrial waste slag and the modification of calcium base desulfurizer for dry desulphurization were reviewed, and the modification methods to improve the desulphurization performance of calcium-containing industrial waste slag were discussed by analyzing the modification mechanism and desulfurization reaction process.
