Problem analysis and improvement measures of pneumatic conveying system in polyolefin plant
This paper introduced the process flow of powder conveying system in HDPE plant,expounded the problems existing in powder conveying system,put forwardsome improvement measures combining with the actual production,such as optimizing the circulating gas return line process of the powder conveying system,adding a check valve,a balance pipe,a insulation board room,a remote cut-off main valve,an emergency emptying valve,replacing the butterfly valve of the blanking line of the cache hopper with short connections,prevented the plant from being forced to shutdown due to the failure of the powder conveying system,extended the operation cycle of the plant,which provided relevant technical support and theoretical basis for the design of polyethylene plant.
