炼炉冷却管的定期清洗可以延长高炉的使用寿命及提高使用安全性,减少能源的浪费。由于不停车清洗,故可在生产过程中有大量的CO、SO_2、H_2S等有毒有害气体泄漏,尤其是CO的浓度大大超过国家卫生标准。酒泉钢铁厂2#炼炉清洗时,经检测,CO浓度超过2,000mg/m_3,超过国家卫生标准几十倍,很容易发生急性中毒事故。7名从事清洗的技术人员的轻、中度急性CO中毒的主要原因有:
The regular cleaning of the furnace cooling tube can extend the life of the blast furnace and improve the use of safety, reduce energy waste. Because it does not stop cleaning, it can be in the production process a large number of CO, SO_2, H_2S and other toxic and harmful gases leak, especially the concentration of CO greatly exceeded the national health standards. Jiuquan Iron and Steel Plant 2 # furnace cleaning, the test, CO concentration over 2,000mg / m_3, more than a few times the national health standards, it is prone to acute poisoning. The seven main reasons for the mild and moderate acute CO poisoning of the seven technicians engaged in cleaning include:
