一、改造设计的原因本钢二铁厂烧结机是五十年代投入生产的,其机尾除尘系统采用多管除尘器。除尘效率极低。因此1988年对机尾除尘进行了第一次技术改造,用电除尘设备取代了原多管除尘器。但是经过几年的运行实践,发现该电除尘系统还存在着以下一些严重问题:①管道破损严重,有的管道半年左右就漏了,不仅在修补管道方面造成了人力和物力的浪费,而且也给生产和维护增加了很多困难;②除尘效果不好,电除尘设备的效率没有达到设计
First, the reasons for the transformation design Benxi Iron and Steel Plant Iron sintering machine is put into production in the fifties, the tail of the dust removal system using multi-tube filter. Dust removal efficiency is very low. Therefore, in 1988 the tail of the dust removal carried out the first technological transformation, the use of electric dust removal equipment to replace the original multi-tube precipitator. However, after several years of operation and practice, it has been found that the ESP system still has some serious problems as follows: ① The pipeline is severely damaged, and some pipes are leaked in half a year, which not only results in the waste of human and material resources in repairing the pipeline but also To the production and maintenance of a lot of difficulties; ② dust removal effect is not good, the efficiency of ESP equipment did not meet the design
