The immersion ultrafiltration is adopted for the mine water pretreatment system of coal mine in Ningxia province, the ultrafiltration inlet is equipped with a hybrid heater. When the hybrid heater is put in commissioning with incoming steam,the outlet pipe of the heater, viz.the inlet pipe of the submerged ultrafiltration, is in vibration.Especially during the immersion ultrafiltration back-washing, the inlet pipe has extremely vibration. This paper mainly focuses on the problems existing in the vibration of the mine water submerged ultrafiltration inlet pipeline, to analyze and study the operating conditions of existing systems and equipment,compare differences in major equipment to dig out the fundamental cause of pipe vibration,then re-adjusting the relevant equipment and pipes to solve the vibration of the inlet pipe. Further more, to provide reference for the selection of hybrid heaters, the design of submerged ultrafiltration distribution channels, the selection of ultrafiltration feed pumps, valves and the system design of pipelines.
