摘　　要：脱硫工艺是电厂生产经营活动中非常重要的一个环节,主要成分为氢氧化钙的电石渣鉴于其活性高、脱硫能力更强的特点,逐渐取代了传统的以石灰石为主的脱硫剂。但由于氢氧化钙和碳酸钙在化学性质上存在着较大的不同之处,对电石渣湿法脱硫工艺的应用研究具有十分必要的意义。文章以陕西北元化工集团热电分厂的130 t/h锅炉为例,对其采用的电石渣-石膏湿法脱硫工艺进行研究,以提高其脱硫的稳定性。In recent years,our country pays more and more attention to environmental protection.As we all know,sulfur oxides can cause serious pollution to the atmosphere and lead to acid rain.Desulfurization process is a very important link in the production and operation of power plant.Calcium hydroxide carbide slag,which is mainly composed of calcium hydroxide,has gradually replaced the traditional limestone based desulfurizer due to its high activity and stronger desulfurization capacity.However,due to the difference in chemical properties between calcium hydroxide and calcium carbonate,it is necessary to study the application of calcium carbide slag wet desulfurization process.Taking the 130 t/h boiler of thermal power plant of Shaanxi Beiyuan chemical industry group as an example,this paper studies the wet desulfurization process of calcium carbide slag gypsum in order to improve the stability of desulfurization.
