Review of research on spray leakage risk of high flash point liquid
In order to study the risk of fire and explosion accidents caused by the spray leakage of high flash point liquid in industrial process,the explosion characteristics of spray were studied in depth and systematically through introducing the gen-eration mechanism of high flash point liquid spray,the influence factors of flame propagation and combustion process in the spray system and droplet system with different particle sizes and the aerosol system,the ignition source of spray,and the two-phase explosion which may cause more serious consequence.The results show that for different liquids,the flammability risk assessment should be carried out according to the conditions under which the leakage may occur in the actual industrial process,so as to avoid serious consequence such as fire and explosion of high flash point liquid spray leakage.The research results can used asreference for the subsequent study on the risk analysis of high flash point liquids.
