喷雾干燥机

SPRAY FLUIDIZER™

SPRAY FLUIDIZER™ 是制造无尘、自由流动、高密度、紧密颗粒的解决方案,它从非热敏感液体进料中凝结固体,例如溶液、悬浮液、浆料或熔化物。

市场对干燥颗粒状产品的需求不断提高。主要原因是,颗粒是无灰尘的,易于处理,因此更能满足更严格的环境要求。通过结合喷雾干燥和流化床技术,GEA 开发了用于生产颗粒产品的连续工艺,即 SPRAY FLUIDIZER™。对于生产高强度产品(如陶粒支撑剂、硫酸盐、有机氯化盐和有机酸)的化工行业,这是一个高效的解决方案。

干燥工艺

SPRAY FLUIDIZER™ 使用了连续工艺。在此工艺中,颗粒形成的预期机制是通过分层且同时干燥液体进料来实现。它结合了喷雾干燥和流化床技术,当液体进料材料被雾化且颗粒能够粘附到流化床中流化的粉末层形成的团聚物或颗粒前,蒸发过程便开始。
The feed is atomized by means of nozzles and sprayed into a fluidized product layer. The granules are continuously withdrawn from the Fluid Bed through a rotary valve maintaining a constant level of the fluidized layer. By subsequent screening, granules of desired particle sizes are discharged from the unit, while any oversized particles can be milled and recycled together with undersized particles and fines recovered in a Cyclone and/or Bag Filter Thus, all product material discharged from the plant will be of the desired particle size. 

A plug-flow fluid bed is applied for second-stage drying and cooling.
