摘　　要：大豆压榨厂的粉尘主要是有机粉尘,又分为大豆粉尘、含溶剂粉尘、豆粕粉尘,在生产中产生粉尘层和粉尘云,可能引发爆炸。在阐述粉尘及粉尘爆炸相关概念基础上,指出大豆压榨厂积尘区域及潜在火源,并提出相关处理措施,包括划分可燃性粉尘爆炸风控区,设置关键安全装置和运行监控装置,制订火源预防措施和设备粉尘控制措施,防止粉尘层阴燃和粉尘云爆炸,按相关标准设计防火防爆厂房结构,大豆预处理车间设计并使用安全风网等。通过相关处理措施以最大限度地降低大豆压榨厂粉尘爆炸隐患,做到安全生产,保护员工和公司的财产。The dusts in the soybean crushing plant are mainly organic dust,and the dusts are also divided into the soybean dust and containing hexane dust and the soybean meal dust.The dust layer and the dust cloud are produced in the production,which may cause explosion.Based on the elaboration of dust and dust explosion related concepts,the dust accumulation areas and potential sources of fire in soybean crushing plants were pointed out,and relevant treatment measures were proposed,including the dividing combustible dust explosion control areas,setting up critical safety devices and running monitoring devices,developing fire prevention measures and equipment dust control measures,preventing dust layer from smoldering and dust cloud explosion,designing fire and explosion-proof plant structures according to relevant standards,and designing and using safety ventilation network in soybean pretreatment workshop,etc.Through relevant measures to minimize the hidden danger of dust explosion in soybean crushing plant,to achieve safe production and protect the property of employees and the company.
