炼钢行业废水废气处理 设计——废气处理炼钢行业废水废气处理 设计——废气处理摘 要本文为韶关某炼钢厂进行了除尘系统的设计。主要内容为根据该厂所提供的各项数据，并结合当地的自然条件，以及当地、该行业的相关标准，选择合适的处理工艺，设计该厂的除尘设施，并且综合考虑该厂的其他方面，进行该厂区的平面布置。该厂年产 86 万吨钢，其中生产过程中废气主要来自于氧化期的大量含尘气体，这些气体中有大量颗粒物和极小部分二噁英，因此设计选用干法除尘，具体工艺为：电炉选用第四孔和屋顶罩共用措施来进行烟气的捕集，精炼炉则通过移动罩来捕集烟气，捕集到的烟气通过间接水冷冷却，之后在通过 LCM7400X2型的脉冲布袋除尘器对烟气进行处理，从而达到相关排放标准排放。关键词：炼钢；除尘系统；电炉；废气处理；布袋除尘器Design of waste water and waste gas treatment in steelmaking industry——Waste gas treatment AbstractThis article designs the dust removal system for a steel mill in Shaoguan. The main content is based on the various data provided by the plant, combined with the local natural conditions, as well as the relevant standards of the local and the industry, select the appropriate treatment process, design the plant's dust removal facilities, and comprehensively consider other aspects of the plant , Layout of the plant area.The plant has an annual output of 860,000 tons of steel. The waste gas in the production process mainly comes from a large amount of dust-containing gas in the oxidation period. These gases contain a large amount of particulate matter and a very small part of dioxins. Therefore, the design uses dry dust removal. The electric furnace selects the fourth hole and the roof cover to share the flue gas capture method, and the refining furnace collects the flue gas by moving the cover. The captured flue gas is cooled by indirect water cooling, and then the dust is removed by the LCM7400X2 pulse bag The f...
