| 为了使应用于炭黑急冷器中的新型脉冲除垢系统达到更好的除垢效果，通过正交试验和数值模拟的方法，以换
热管壁面峰值压力作为评价指标，分析了喷吹压力、喷吹距离、喷嘴直径和喷吹时间对除垢性能的影响。得到了影响除
垢效果因素的主次顺序依次是喷吹压力、喷吹时间、喷嘴直径和喷吹距离；在所选取的水平范围内，当喷吹压力为2.0
MPa，喷吹时间取0.2-0.3 s，喷嘴直径为7.5 mm，喷吹距离为40 mm时，脉冲除垢系统能取得较好的效果。所得到的分
析结果为脉冲除垢系统的设计优化提供了理论依据，为炭黑急冷器的工程化安全应用奠定了基础。 |

| ln order to make the new pulse descaling system applied to carbon black quencher achieve better descaling
result . the orthogonal experiment and numerical simulation method were applied to analyse how much impact the injection
pressure,injection distance.nozzle diameter and injection time make on the descaling result, with peak pressure on the
surface of heat exchange tube as the appraisal target. The results show that the primary and secondary order of the factors
that influence the descaling result is injection pressure ,injection time .nozzle diameter and injection distance in turn. The
results also indicate the preferable values in the selected level scope , such as the injection pressure = 2. 0 MPa , injection
time =0. 2 - 0. 3 s. nozzle diameter = 7. 5 mm and injection distance = 40 mm. The results provide an important
theoretical basis for design optimization of pulse descaling system and lay the foundation in security engineering of
quencher application. |
