Analysis of Common Problems and Disposal Measures of Vacuum Filtration Machines

The vacuum filter is a crucial equipment for the flash evaporation system of GE coal water slurry gasification process, and the subsequent sequence is crucial! By utilizing vacuum negative pressure filtration process, solid-liquid separation of high concentration filtrate after flocculation and sedimentation is achieved. The production operation process includes filtration, washing, slag unloading, and filter cloth cleaning. Focus on the common problems that have occurred after the vacuum filter machine was put into normal production and operation. Analyze the reasons one by one, propose targeted disposal and optimization measures, and achieve continuous operation and filtration of the suction filter. This article mainly focuses on the common problems that have occurred in the past operation process, such as water carrying in the filter cake, deviation of the filter cloth, insufficient vacuum degree, unclean filter cloth falling out of the funnel, and slipping of the tape. Corresponding solutions and innovative transformation measures are proposed. The operation of the vacuum filter is directly related to the changes in water quality of the coal water slurry gasification unit and the impact of long-term continuous operation. During the production process, common problems that cannot be identified and dealt with in a timely manner may cause significant fluctuations in operating conditions.
