Design of Polyethylene Stirred Tank Reactor
Abstract：The content is the design of Polyethylene stirred tank reactor. Structure using jacket.The medium in tank is Polyethylene.The design pressure is 2.8MPa.The medium in jacket is water vapor.The design pressure 2.0MPa.The main material is Q345R.Design method using the conventional design method of pressure vessel.According to GB150-98《Steel pressure vessel》technical enforcement.The design mainly includes the design options,reactor(tank and jacket)strength and structural design,the design of stirring device ,the design of drives and design other parts of the reactor.The results of the design calculations is accurate.In line with the actual polymerization reactor of the project.Drawing conform national standards for mechanical drawing requirements.Simple structure,reasonable,better than the actual equipment.The material mixed sufficient in reactor,uniform.Stirring effect to meet the production requirements.Easy material to form axial flow pattern between each other
dispersed
The equipment has good mixed performance,low energy consumption,simple structure,easy operation and maintenance.And easy for material to form axial flow pattern between each other dispersed.Can increase the area of contact of the different physical.So the prospects of stirred tank reactor’s application is broad.
KeyWords: stirred tank reactor；stirring equipment;drives equipment;jacket
