Ammonium sulfate solution concentrating and drying system and process and application

The invention relates to an ammonium sulfate solution concentrating and drying system and process and an application, and belongs to the field of chemical engineering. The system comprises a cyclone, a vacuum belt filter, a vacuumizing system, an air blower, a hot air heater, a flash dryer, a cyclone dust collector, a cyclone dust collector storage tank, a cloth bag-type dust collector, an induced draft fan, a hopper, a spiral conveyor, a packaging machine, a feed liquid tank, a feed liquid pump, an auxiliary pipeline and the like. The system is characterized in that the device performs step-by-step dehydration treatment on an ammonium sulfate solution conveyed by an external system, so that the water content of a final ammonium sulfate solid material is reduced to be 0.5% or less, and the standard of direct packaging and export sales is met. 本发明涉及一种硫酸铵溶液提浓干燥系统与工艺、应用，属于化工领域；所述包括旋流器、真空带式过滤机、抽真空系统、鼓风机、热风加热器、闪蒸干燥机、旋风除尘器、旋风除尘器储料罐、布袋除尘器、引风机、料斗、螺旋输送机、包装机、料液槽、料液泵及附属管线等构件组成。其特征在于本装置对外系统输送来的硫酸铵溶液进行逐级脱水处理，使最终的硫酸铵固体物料含水
