[中国石化新闻网]岳阳兴长聚丙烯厂采用间歇式液相本体法制聚丙烯工艺,该工艺生产的粉料聚丙烯经闪蒸后,通过包装岗位包装出厂。由于聚丙烯粉料颗粒很小,粉尘大、落地多、易损耗,给包装岗位和包装工人带来很大困扰,并对环境卫生造成污染。为彻底解决粉尘飞扬难题,经过多次技术讨论,先后在三台闪蒸釜包料区域,进行设备改造和试验:通过在出入口加装折留板分散气流,加装帆布袋多次粉尘过滤,再进行水 [Sinopec News] Yueyang Xingchang polypropylene plant using batch liquid phase bulk polypropylene legal process, the process of production of polypropylene powder after flashing, packaging post by packing factory. Due to the small particle size of polypropylene powder, large dust, floor and more, easy to wear and tear, packaging jobs and packaging workers have caused great troubles and pollution of the environment and health. In order to completely solve the problem of flying dust, after several technical discussions, we successively retrofitted and experimented with equipment in the areas of the three flash kettle kits: the diversion of air flow through the installation of a folding plate at the entrances and exits, the installation of multiple dust filters in canvas bags, Re-water
