Abstract
The invention provides an electrostatic separation method and equipment for oil slurry, belonging to the technical field of solid-liquid separation. The electrostatic separation method comprises the following steps: adding a dispersing aid into to-be-treated oil slurry, uniformly mixing, and carrying out centrifugal filtration, so as to pretreated oil slurry; mixing the pretreated oil slurry with glass beads, and externally applying an electric field; separating the adsorbed glass beads, so as to obtain purified oil slurry. By utilizing the electrostatic separation method, a fine particle catalyst contained in the to-be-treated oil slurry can be rapidly and efficiently separated. The invention further provides the electrostatic separation equipment utilizing the electrostatic separation method.
Description
technical field [0001] The invention relates to the technical field of solid-liquid separation, in particular to an electrostatic separation method for oil slurry and electrostatic separation equipment for oil slurry. Background technique [0002] The catalytic cracking of petroleum refers to the process in which petroleum undergoes a cracking reaction under the action of a certain temperature and a catalyst, and is converted into cracked gas, gasoline and diesel oil and other products. Catalysts (Al 2 SiO 4 etc.), it is necessary to separate this part of catalyst impurities from the oil slurry in production so as to enter the follow-up operation. [0003] At present, the commonly used slurry catalyst separation methods mainly include natural sedimentation method, filtration separation method and centrifugal separation method, among which: [0004] The natural sedimentation method has the advantages of simple equipment, low operating cost, and easy operation, but the natur...
