Description

Multistage cyclone sand removal device for fracturing flowback fluid Technical Field The utility model relates to the technical field of flowback fluid treatment, in particular to a fracturing flowback fluid multistage cyclone sand removal device. Background In the fracturing operation process, a large amount of fracturing flowback fluid can be generated, and the fracturing flowback fluid contains a large amount of solid substances, impurities with different particle sizes, microorganisms, bacteria and the like, and if the fracturing flowback fluid is not subjected to effective treatment and is directly discharged, serious pollution can be caused to the environment, and meanwhile, the waste of water resources can be caused. At present, the existing fracturing flow-back fluid treatment device has a plurality of defects in the aspect of filtration. On one hand, some devices only rely on simple gravity sedimentation or a single filtering structure to carry out solid-liquid separation, the filtering efficiency is low, solid substances and impurities in the flowback fluid cannot be separated out rapidly and effectively, and the requirements on the treatment speed in actual production are difficult to meet, on the other hand, some devices have a certain filtering function, but the filtering precision is limited, the removing effect on fine particles and suspended substances is poor, so that the treated liquid still contains more impurities, and the recycling or emission standard cannot be met. In addition, in the filtering process, impurities easily block the filtering component, influence the normal operation of the device, require frequent shutdown cleaning, and increase the maintenance cost and the production interruption time. In addition, the existing device is single in impurity cleaning mode for adhering to the filtering component, is difficult to clean thoroughly, can influence the filtering effect and the service life of the device after long-term use, and in view of the fact, the device is deeply researched for the problems, and the device is generated.
