Discussion on the cause of Formation and Safety Control of Fog in Matte Graining Area
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.
