加氢装置氢气泄漏喷射火行为及热灾害特征研究
Study on Hydrogen Leakage Ejection Fire Behavior and Thermal Hazard Characteristics of Hydrogenation Unit
摘要
Abstract
In petrochemical industry,hydrogenation units are faced with the risk of hydrogen leakage,fire and explosion due to the easy leakage and flammability of hydrogen.At present,most of the research focuses on the leakage of hydrogenation unit.Based on this,the flame length,temperature and heat radiation distribution of jet fire induced by large aperture constant pressure hydrogen discharge in hydrogenation unit were experimen-tally studied.The results showed that the nozzle diameter and leakage pressure significantly affected the flame length and thermal disaster field distribution.The larger nozzle diameter caused the flame length to increase,and the temperature distribution also changed accordingly,forming a higher heat radiation intensity,when the leakage pressure was 1.0 MPa,the heat radiation intensity increased from about 6 kW/m2 when the nozzle di-ameter was 4 mm to about 15 kW/m2 when the nozzle diameter was 10 mm.Under the same nozzle diameter,the increase of leakage pressure led to the enhancement of thermal radiation,that was,when the nozzle diameter was 10 mm,the thermal radiation intensity at the leakage pressure of 1.0 MPa was about 3 times that at the leakage pressure of 0.2 MPa.In addition,the power function distribution function of hydrogen emission intensi-ty and normalized flame length was established.The research results provided a scientific basis for the safety management,fire prevention and control and emergency response measures of hydrogenation units,and further promoted the safe development of hydrogen technology.关键词
