A device for removing solid impurities in civil aviation jet fuel

Abstract

The invention discloses a civil aviation jet fuel solid phase impurity removing device. The civil aviation jet fuel solid phase impurity removing device comprises a pressure sealing tank and a cyclone, and is characterized in that a separating plate is arranged at the middle-lower part of the pressure sealing tank, the periphery of the separating plate is welded with the inner wall of the pressure sealing tank in a sealing manner, a mounting hole is formed on the separating plate, a cone part of the cyclone is inserted into the mounting hole to be in sealing connection with the separating plate, the separating plate divides the pressure sealing tank into two independent sealing units, a feeding pipe of the cyclone penetrates through the wall of the pressure sealing tank to be in sealing connection with the wall of the pressure sealing tank, a high-level discharge pipe is arranged at the top of the pressure sealing tank, a lower-level blowdown pipe is arranged at the bottom of the pressure sealing tank, and a lower-level blowdown pipe is arranged on the wall of the pressure sealing tank above the separating plate. The civil aviation jet fuel solid phase impurity removing device can completely replace gravity settling impurity removal equipment in the civil aviation jet fuel impurity removal process, and can effectively improve the impurity removal efficiency and the equipment processing capacity, reduce the equipment investment and occupied area and prolong the service life of a filter screen in the lower level.

Description

technical field [0001] The invention relates to the technical field of rotating fluid solid-liquid separation and gravity sedimentation classification, in particular to a technology for separating solid impurities in civil aviation fuel by using a rotating flow field and a fluid gravity field. Background technique [0002] At present, the removal of solid phase impurities in civil aviation jet fuel mainly adopts the method of gravity sedimentation and filtration. Gravity sedimentation refers to the method of clarification by the natural sedimentation of impurities by their own gravity. The gravity sedimentation method is simple and reliable, but its disadvantages are slow sedimentation speed and low processing capacity. For the purification of civil aviation jet fuel with a huge volume, a large sedimentation tank needs to be built, and it is inconvenient to transfer, and the equipment occupies a large area and investment, which limits the scope of use. . The filtration met...
