一、前言上钢一厂的30吨LD转炉的煤气净化回收装置是在1966年投产的,是我国第一套净化回收装置。经过廿余年的实践证明,该系统是有效的,烟气排尘浓度低于国家的排放标准,吨钢烟气回收量通常达到50m~3/t钢,CO含量为45～55%。但是由于缺乏煤气成份检测系统,因而不能进行自动检测和控制,与国外先进水平有较大的差距,并且回收的产量和质量也不稳定。为此在1983年,上钢一厂从国外引进了二套转炉煤气在线分
First, the foreword On a steel plant 30 tons of LD converter gas purification recovery unit was put into operation in 1966, is China’s first set of purification recovery unit. After more than 20 years of practice, the system has proved effective. The concentration of flue gas dust emission is lower than the national emission standards. The recovery of flue gas per ton of steel usually reaches 50m 3 / t steel and the CO content is 45-55%. However, due to the lack of gas composition detection system, it can not be automatically detected and controlled, with a big gap with the advanced foreign countries, and the output and quality of the recovery are also unstable. To this end in 1983, a steel plant from abroad introduced two sets of converter gas online points
