Continuous oil slurry static separation device, system and method

Abstract

The invention provides a continuous oil slurry static separation device, system and method. The separation device comprises an outer tube, wherein an inner tube is in concentric arrangement in the outer tube; a plurality of separation plates in vertical arrangement are arranged between the inner tube and the outer tube; a top cover rotationally connected with the outer tube is arranged on the topof the outer tube; an oil slurry inlet and a flushing liquid inlet are formed in the top cover; a sieve plate is arranged at the bottom of the outer tube; a bottom cover rotationally connected with the sieve plate is arranged at the bottom of the sieve plate; an oil slurry outlet and a flushing liquid outlet are formed in the bottom cover. The flushing liquid is injected from the flushing liquid inlet and is discharged from the flushing liquid outlet; then, the top cover is rotated, the oil slurry is injected into the treatment region from the oil slurry inlet for purification treatment; next,the bottom cover is rotated, the treated oil slurry is discharged from the oil slurry outlet; the steps are performed repeatedly in order. The continuous production is realized; the flushing processand the purification process are not mutually interfered; the flushing is convenient; the separation efficiency is high; the regulation can be performed according to different work conditions; the application range is wide; the automatic control can be easily realized.

Description

technical field [0001] The invention relates to the technical field of oil slurry purification treatment, in particular to a continuous type oil slurry electrostatic separation device, a separation system and a separation method. Background technique [0002] At present, the annual processing volume of catalytic cracking in my country has exceeded 150 million tons, and the output of oil slurry accounts for about 5-10% of the processing volume of catalytic cracking. The output of oil slurry, a by-product of catalytic cracking, is increasing year by year. Since the catalytic cracking oil slurry contains a large amount of catalyst particles and condensed ring aromatics, it is easy to cause the catalyst to coke and release a large amount of heat during the recycling process, which reduces the safety and stability of the device; moreover, it seriously affects the performance of catalytic cracking. Product nature and quality. Therefore, for catalytic cracking oil slurry, in order...
