导读:什么是粉尘爆炸?指粉尘在爆炸极限范围内,遇到热源(明火或温度),火焰瞬间传播于整个混合粉尘空间,化学反应速度极快,同时释放大量的热,形成很高的温度和很大的压力,系统的能量转化为机械功以及光和热的辐射,具有很强的破坏力。

粉尘爆炸的严重性和除尘设备的必要性

粉尘爆炸的预防措施

1、消除粉尘源。可用的除尘措施有封闭设备、通风排尘、抽风排尘或润湿降尘等。除尘设备的风机应装在清洁空气一侧。其中易燃粉尘不能用电除尘设备,金属粉尘不能用湿式除尘设备。设备启动时应先开除尘设备,后开主机;停机时则正好相反,防止粉尘飞扬。粉尘车间各部位应平滑,尽量避免设置一些无关设施(如窗幕、门帘等)。管线等尽量不要穿越粉尘车间,宜在墙内敷设,防止粉尘积聚,另外,在条件允许下,在粉尘车间喷雾状水,在被粉碎的物质中增加水分也能促使粉尘沉降,防止形成粉尘云。此外,在车间内做好清洁工作,及时人工清扫,也是消除粉尘源的好方法。
