一、前言中小型炼钢电弧炉如何排烟除尘一直是个难题。位于浦东开发区的上海某船厂铸锻分厂,有炼钢电弧炉一台,原有的排炯除尘设施,因年久失修已不能正常使用.炼钢炉生产时,黄烟从车间气楼排放到周围的大气中,影响了景观,污染了环境。我院于1991年初承担了该炼钢电弧炉排烟除尘改造工程的设计。二、排烟除尘系统设计 I. Introduction How small and medium-sized steelmaking electric arc furnaces emit smoke and dust has always been a problem. Shanghai Shipbuilding and Forging Plant, located in the Pudong Development Zone, has a steel-making electric arc furnace. The original dust collection and drainage facilities cannot be normally used due to disrepair. When steelmaking furnaces are produced, yellow smoke is discharged from the workshop floor. In the surrounding atmosphere, it affected the landscape and polluted the environment. In early 1991, our institute undertook the design of the dust-removal and renovation project of the steelmaking electric arc furnace. Second, smoke and dust removal system design
