Oil slurry filtering system and oil slurry filtering method

The invention relates to an oil slurry filtering system and an oil slurry filtering method. The filtering unit of the oil slurry filtering system is provided with at least one filter, and an oil slurry inlet pipeline, a filtered oil outlet pipeline and a filter residue discharge pipeline which are respectively communicated with each filter, and a pinhole-free filter bag made of a flexible filtering material is arranged in each filter. According to the oil slurry filtering method, oil slurry enters the filter through the oil slurry inlet pipeline communicated with the filter to be filtered, andoil after filtration is pumped out from the filtered oil outlet pipeline. By adopting the oil slurry filtering system and the filtering method, the long-term stable operation of the oil slurry filtering process solves the problems that the filtering material is easily blocked by high-viscosity colloid impurities, the regeneration efficiency is poor and the removal efficiency is low. 一种油浆过滤系统和油浆过滤方法，所述油浆过滤系统的过滤单元中设置至少一个过滤
