一、前言 贵溪冶炼厂炼铜设备是从日本成套引进的,利用闪速炉和转炉的冶炼烟气制取硫酸,年产硫酸36万吨。 闪速炉的生产是连续进行的,但转炉生产却是周期进行的,因此送往硫酸生产系统的烟气流量和压力都随着转炉的吹炼与停吹而波动,且波动幅度很大。这样,转炉的周期生产将使闪速炉炉膛压力控制困难,硫酸生产系统设备也可能发生损坏,工厂正常
I. Introduction Guixi smelter copper smelting equipment imported from Japan complete set, the use of flash furnace and converter smelting flue gas sulfuric acid, with an annual output of 360000 tons of sulfuric acid. The production of the flash furnace is continuous, but the converter production is cyclical. Therefore, the flow and pressure of the flue gas sent to the sulfuric acid production system fluctuate with the blowing and blowing of the converter and fluctuate greatly. In this way, the cycle of converter production will make flash furnace pressure control difficult, sulfuric acid production system equipment may also be damaged, the factory normal
