Technical Field

Background
The catalytic cracking slurry oil is a byproduct of a catalytic cracking device, and is generally sold as waste oil at low price or burnt as fuel, so that not only can a furnace mouth generate corrosion and coking, but also great waste of resources is caused. The main component of the catalytic oil slurry is polycyclic aromatic hydrocarbon, and high-quality petroleum coke, carbon black, rubber softening oil and the like can be produced by deep processing. However, the oil slurry contains high catalyst particles, which brings difficulty to the comprehensive utilization of the oil slurry. Therefore, the catalyst particles in the slurry oil need to be treated to meet the requirements of different products on the catalyst particles.
As the particle size of solid-phase particles in the FCC slurry is in the range of 0-80 μm, the proportion of particles with the particle size of less than 20 μm is relatively heavy. Compared with a settling method, a filtering method, a cyclone separation method and the like, the electrostatic separation method has the advantages that micron-sized catalyst particles are removed more obviously when catalytic oil slurry is treated, and the pressure drop is small. The electrostatic separation is to generate a non-uniform high-voltage electric field by a high-voltage power supply, catalyst particles are polarized by the electric field to generate non-uniform coulomb force, and then the catalyst particles move directionally to realize the removal of the particles. In order to enhance the local electric field strength, it is necessary to incorporate glass fillers in the electrostatic separator. After being polarized, the catalyst particles are adsorbed at the contact point position of the filler, when the catalyst particles adsorbed by the filler reach saturation, a back washing measure is adopted for cleaning, and the operation of the next period is carried out again. The backwashing aims to clean the glass bead filler, the conventional method is mostly a mode of directly performing liquid or gas-liquid mixed backwashing on an electrostatic separator, complete cleaning and cleanness of the glass filler are difficult to ensure, the consumption of backwashing liquid is high, and high backwashing pressure needs to be ensured.
