Abstract:

Based on the theory of fluid mechanics and by calculation and comparison between cyclone dust collector and gravity dust collector,confinement reasons are found for holding back the cyclone collector as primary deduster for CDQ unit.Design selection,fabrication,installation and execution result,etc.in practice are introduced.The study result shows that the cyclone collector can replace the conventional primary deduster even the secondary one in the CDQ unit,and can meet the process requirement with features such as simple process flow,low investment and good performance,etc.,with dust content in circulating gas lower than 1 g/m3.
