Abstract

The invention relates to the technical field of solid-liquid separation, specifically to a slurry oil purifying method, a slurry oil purifying device and slurry oil purifying equipment. The slurry oilpurifying method provided by the invention comprises the following steps: heating catalytically cracked slurry oil to a set temperature; and subjecting the heated catalytically cracked slurry oil topurifying treatment through multistage electric fields, wherein the multistage electric fields comprise at least three electric fields; the field intensities of a plurality of electric fields are successively reinforced; and the catalytically cracked slurry oil firstly passes through the weakest electric field in the plurality of electric fields. The slurry oil purifying method provided by the invention can realize deep removal of solid superfine particles of a catalyst, can significantly improve the removal efficiency of solid particles and meets the purifying requirements of the catalytically cracked slurry oil on high purity. Through construction of multistage gradient electric fields, tripping of a power supply due to excessive current can be avoided, so safe and stable operation of the device is guaranteed, and the separation efficiency of static electricity can be further improved.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation, in particular to an oil slurry purification method, an oil slurry purification device and oil slurry purification equipment. Background technique [0002] With the increasing trend of crude oil becoming heavier and inferior, crude oil processing becomes more difficult, and the yield of light oil products decreases. The deep processing and full utilization of heavy oil have become the focus of attention of the global oil refining industry. At present, catalytic cracking has become one of the main means of deep processing of heavy oil. Since the catalytic cracking oil slurry contains a large amount of catalyst particles and polycyclic aromatic hydrocarbons, it is easy to make the catalyst coke and release a lot of heat during the recycling process, which reduces the safety and stability of the device and seriously affects the properties and quality of catalytic cracking products. ....
