摘　　要：风、水淬是冶炼厂常用的粒化方式,但在潮湿天气,尤其是冬季该过程会不同程度地产生雾气,降低了生产现场能见度,既影响生产连续又产生安全隐患。为此,针对某冶炼厂风淬粒化的实际情况,分析其雾气产生的原因。结果表明:减少雾气的有效办法为降低空气湿度和提高空气温度,降低空气湿度是重点,而粒化室系统负压、冷却程度、设备结构、所处环境及设施所处位置等均一定程度影响空气湿度,其中系统负压是主要因素,并针对性提出了相应的安全治理方案。Wind quenched and water quenched are the usual granulation methods in smelters,but in wet weather,especially in winter,the process will produce fog in different degrees,which will reduce the visibility of production site and affect the continuity of production as well as produce potential safety hazards.Therefore,according to the actual situation of air-quenched granulation in a smelter,the causes of fog formation are analyzed.The results show that the effective way to reduce fog is to reduce air humidity and increase air temperature,the air humidity is affected to a certain extent by the negative pressure of the granulated chamber system,the degree of cooling,the structure of the equipment,the environment and the location of the facilities,among which the negative pressure of the system is the main factor,and the corresponding security management scheme is put forward.
