筛焦粉尘捕集
dust collection in coke screening
shal」扭0 fenchen buji筛焦粉尘捕集(dust。olleetson of cokescreening)把筛焦过程中产生的粉尘抽吸入集尘设备内加以处理，使空气得到净化的除尘措施。是筛焦作业的一个重要组成部分。经湿法熄焦后的焦炭表面温度约为50~75℃。在此后的破碎、筛分和转运至贮焦槽的整个处理过程中，焦炭表面的蒸汽与焦炭粉尘一起逸散到作业场所的空气中，空气含尘量一般可达到200~200omg/m3空气。干法熄焦后的焦炭，在此过程中逸散的粉尘更多。20世纪40年代焦化厂开始采用机械通风除尘法处理湿法熄焦的筛焦粉尘。这种方法是用抽风机将作业场所的含尘空气抽吸到一起进行除尘。现在常用的除尘设备有湿法洗涤器和布袋除尘器。中国自50年代开始在焦化厂中设置机械通风除尘设备，但设备易被腐蚀，不能长期运转，因而采用自然通风把水蒸气及粉尘直接排入大气中。此法虽然可减少作业场所空气含尘量，但污染了附近的大气环境。70年代初，在焦炭辊动筛上装设抽风机，筛焦粉尘则用泡沫除尘器处理，处理后排入大气的空气含尘浓度小于15Omg/m“空气。此项技术已在中国焦化厂得到推广。为了解决通风除尘设备的腐蚀间题，80年代中期，集尘设备、抽风机和管道改用玻璃钢或不锈钢制作。从胶带输送机头部落入贮焦槽的焦炭产生大量粉尘，中国一直沿用在贮焦槽上设自然排气管的办法将含尘气体排入大气。排出气体中焦炭粉尘浓度约为100一25omg/m，空气。自然排气管用玻璃钢制作，以减轻构筑物的荷重。采用湿法熄焦时，通风除尘管道内部易被蒸汽冷凝水湿润，粘结粉尘，引起管道堵塞，故需及时清理。在北方寒冷地区，还要采取防冻措施。干法熄焦时的筛焦粉尘，一般多采用袋式过滤器捕集。袋式过滤器收集的焦粉在加湿后，既可送回粉焦胶带输送机上，也可用真空吸送罐车直接送往烧结厂，从而消除了二次污染。 (贺儒良李秀林)
