炭黑生产企业非粉尘爆炸危险区域划分的深度探讨与系统论证

In-Depth Discussion and Systematic Demonstration on the Determination of Non-Dust Explosion Hazardous Areas in Carbon Black Production Enterprises

摘要: 通过实验对炭黑粉尘云的“可爆性”、最小爆炸浓度MEC、最小爆炸点火能MIE以及最低着火温度MIT进行测试，将实验结论与过往研究数据，同时结合实际炭黑生产工艺控制参数做比对分析得出：尽管炭黑粉尘在特定条件下呈现“可爆性”，但在粉尘防治得当和安全联锁系统可靠的前提下，炭黑生产企业理论上可判定为非粉尘爆炸危险区。

Abstract: Through experiments, the “explosibility”, Minimum Explosible Concentration (MEC), Minimum Ignition Energy (MIE), and Minimum Ignition Temperature (MIT) of carbon black dust clouds were tested. By comparing and analyzing the experimental conclusions with previous research data, and combining them with the actual process control parameters of carbon black process, the following conclusion is drawn: Although carbon black dust exhibits “explosibility” under specific conditions, carbon black production enterprises can be determined as non-dust explosion hazard zones on the premise that dust prevention and control measures are properly implemented and the safety interlock system is reliable.
