An electrostatic separator and cleaning method that can change the packing method

Abstract

The present invention proposes an electrostatic separator and a cleaning method capable of changing the packing accumulation mode, so that the packing accumulation mode can be conveniently changed without disassembly in the electrostatic separator, and solves the problem of insufficient backwashing of the packing material in the prior art. The technical problems of low efficiency and difficult packing drying include the cylinder body, the coaxial electrode column, a number of packing plates between the inner electrode and the cylinder body, and the packing plates are equipped with assembly column insertion holes, fixed column insertion holes, and moving column Jack holes, electrode holes and filler placement holes, the fillers are arranged on the filler plate, the position of the odd-numbered plates is fixed by the fixed column, and the horizontal movement of the even-numbered plates is controlled by the moving column to change the packing accumulation method.

Description

technical field [0001] The invention relates to the technical field of catalytic cracking oil slurry purification, in particular to an electrostatic separator capable of changing the packing packing mode and a cleaning method thereof. Background technique [0002] With the continuous improvement of my country's catalytic cracking processing capacity, the output of catalytic oil slurry is also increasing year by year, and the output of oil slurry generally accounts for about 5% to 10% of the catalytic cracking processing volume. Since the main components of catalytic oil slurry are polycyclic aromatic hydrocarbons and catalyst particles, it is easy to generate coke and release a lot of heat during the recycling process, which greatly reduces the safety and stability of the device; it also seriously affects the quality of catalytic cracking products. . Therefore, it is necessary to carry out partial external rejection treatment on the catalytic oil slurry, which creates a nee...
