目前中国多数企业中大型工业机械设备的蒸汽供热系统有近50%的凝结水没有完全回收和利用,造成每年数亿吨水资源的损失及热量的白白浪费。造成这一问题的原因很大程度上是工业机械设备蒸汽供热系统的蒸汽在凝结过程中,其中的大量气体杂质溶入本应非常纯净的凝结水中,腐蚀凝结水的载体——换热设备及输送管道,同时腐蚀凝结水。细致分析工业上蒸汽凝结水腐蚀的原因,再提出相应的防治措施,增强工业上蒸汽凝结水的回收利用率,从而降低水资源和热量的损失,还能大大延长工业机械设备的使用寿命。
At present, nearly 50% of the condensate in the steam heating system of large-scale industrial machinery and equipment of most enterprises in China is not completely recovered and utilized, resulting in the loss of hundreds of millions of tons of water resources every year and the waste of heat. The cause of this problem is largely due to the steam in the steam heating system of industrial machinery and equipment in the condensation process, in which a large number of gas impurities dissolved into the condensate should be very pure, corrosive condensate carrier - heat transfer equipment And the pipeline, while corrosion condensate. Detailed analysis of the causes of industrial steam condensate corrosion, and then put forward appropriate prevention and treatment measures to enhance industrial steam condensate recovery rate, thereby reducing the loss of water resources and heat, but also greatly extend the service life of industrial machinery and equipment.
