炭黑尾气在生产中的回收利用

针对炭黑尾气水分高、着火点高、易爆燃的特性,在炭黑尾气利用时,要解决稳定燃烧、预热煤气、平衡尾气压力及防止炭黑滤袋泄漏等问题。结合实际生产中炭黑尾气的成分,采取了相应的安全措施,完善了炭黑系统和锅炉系统衔接的各项指标,取得了较为显著的经济效益。

Recovery and Utilization of the Carbon Black Tail Gas

The carbon black tail gas has the features of high moisture content and high ignition temperature, be- sides, it is combustible and explosive. While using such gas, due attention should be paid on its stable combustion, gas preheating, balanced pressure and leakage prevention of the filter bag. Proper precaution measures were taken based on the composition of the carbon black tail gas that generated during actual operation, thus perfecting various indexes of the carbon black system and the boiler system and gaining remarkable economic benefits.
