Risk Analysis And Countermeasures Of Converter Gas Reclaiming System In Hesteel Tangsteel

In iron and steel enterprises,the safety of gas system is particularly prominent.The river steel hot rolling department of Tangshan Iron and steel converter gas recovery system as the research object,the technological process,equipment and working environment and staff to carry out risk analysis and identification of major hazard sources,including gas recovery system for high temperature operation,high temperature flue gas discharge line converter,safety measures in place are the main risk factors causing gas accidents;the equipment defects and operator error are the main cause of the accident,using numerical calculation method of qualitative and quantitative research found that: the gas recovery system in the supply of raw materials and gas cleaning and recycling at the risk level is higher,which prone to gas poisoning and fire accidents.According to the "identification" of major hazard of dangerous chemicals identified that 20000m3 of hot rolled steel River Tangshan steel converter gas cabinet belongs to the three major risk sources.Technology of gas recovery system can be update so that effect of dust removal and equipment security can be improved.Gas recovery system that has perfect sensitive chain protection,alarm and cutting system,and improves security level and stability,which reduces resource consumption and save energy.The converter gas systemexist possible risky issues when risk assessment is implement base on explosion and fire index evaluation which made by American DOW Chemical Company.It is necessary to strengthen the security management.After implement security remedying management,the risk level decreased to “light”,which is “safety status”.The value of the compensation system is small,so the actual maximum possible property loss MPPD is smaller according to the value of the compensation system.Base on the result of risk analysis,in addition to the technological transformation of dust removal system,the gas recovery system management measures is proposed,the foundation for the creation of the "essential safety" enterprises is lay,the safe operation of the enterprise guaranteed.It provide a reference for the similar enterprises to strengthen the safety of converter gas recovery system.
