1、 I 摘 要 在钢铁厂的转炉、平炉、高炉等车间,烟气污染都十分严重,尤其是高炉出铁 场,在出铁期间所散发的烟尘是钢铁厂对大气主要污染源之一。随着高炉强化冶炼 和大型化,如果不采取有效的烟尘捕集及净化措施,那么,所带来的环境污染将会 日益严重。为降低工人的劳动强度,保护工人身体的健康,以及随着环境保护排放 标准的日益严格,迫切需要对高炉出铁场的烟尘进行治理。 本文针对出铁场烟尘治理采用可编程序控制器 PLC 和 WINCC 监控软件设计了 除尘自动控制系统;PLC 根据现场实际情况控制布袋除尘器的动作,使除尘器高效 率除尘, 通过组态软件,能在画面中观察系统工作状态,对系统进行安全有效控 制。实
2、践表明 ,该控制系统结构简单 ,操作简便,除尘效率高 ,运行可靠。 关键词 出铁场,除尘系统,PLC 自动控制 II ABSTRACT In the steel plant converter, open hearth, blast furnace, such as workshops, smoke pollution are very serious, especially blast furnace in the iron emitted during soot is a steel plant on the atmospheric main sources of pollution. W
3、ith the blast strengthen smelting and large, if you do not take effective dust trap and purification measures, then the environmental pollution will become increasingly serious. To reduce labor intensity, physical health protection of workers, as well as increasingly stringent environmental emission
4、 standards, the urgent need for blast furnace soot to govern. In this paper, casthouse dust control using programmable logic controller PLC and WINCC monitoring software designed dust control system; PLC according to the actual situation under control baghouse action, so that high-efficiency dust removal, through the configuration software, can the screen observing system status, the system for security control. Practice shows that the control system is simple, easy operation, dust, high effic
