摘　　要：根据现在的燃煤锅炉的运行情况,采用石灰作为脱硫剂进行脱硫,配套后续的水、污泥处理系统。要求废气的二氧化硫的浓度达到广东省地方标准《锅炉大气污染物排放标准》(DB44/765-2010)A区标准。该法具有工艺实用稳定、控制精确、操作简便、作业环境良好的特点。本方案工艺技术选用成熟的逆流喷淋塔,整个工艺系统由烟气脱硫系统、碱液储备系统、吸收剂循环系统、脱硫废水排放系统、工艺水系统及电气与仪表控制系统等几部分组成。该系统具有脱硫效率高、阻力小、运行安全、构造简单、不存在结垢堵塞等特点。According to the present situation of coal-fired boiler,using lime as a desulfurization agent for desulfurization,supporting the follow-up of water,sludge processing system.Required concentration of sulfur dioxide emissions from provincial standard ＂boiler emission standards for air pollutants＂（DB44/765-2010） A district standards.The method has the process of practical stability,precise control and easy operation,the characteristics of a good working environment.The program selected a mature technology countercurrent spray tower,the entire process system from the flue gas desulfurization system,alkali reserve system,the absorbent circulation system,desulfurization wastewater discharge systems,process water system and electrical and instrumentation control system parts composition.The system has the desulfurization of high efficiency,small resistance,operational safety,simple structure,so there is no plug fouling.
