上钢一厂二转炉车间原系侧吹转炉,1983年6月改为3座15t氧气顶吹转炉投产后,3座炉子的煤气回收已于1984年10月投产。 煤气回收系统采用“未燃法”净化工艺。转炉煤气经汽化冷却烟罩、两段文氏管净化除尘、脱水器和除尘风机送至10000m~3煤气柜,用煤气加压机送到使用部门。在新技术使用方面,用了椭圆矩形可调文氏管及背包式重力脱水器,系统阻损降低。在热工 On the steel plant two converter workshop original side of the converter, in June 1983 changed to three 15t oxygen top blown converter put into operation, the three gas stoves recovery was put into operation in October 1984. Gas recovery system using “unburned Law” purification process. Converter gas cooling by vaporization hood, two sections of Venturi purification dedusting, dehydration and dust blower to the 10000m ~ 3 gas tank, with gas pressure to the user department. In the use of new technologies, the use of elliptical rectangular adjustable venturi and backpack-type gravity dehydrator, the system reduces resistance. In the heat
