Electrostatic separator capable of changing packing stacking mode and cleaning method thereof

Abstract

The invention provides an electrostatic separator capable of changing a packing stacking mode and a cleaning method thereof, the packing stacking mode can be conveniently changed in the electrostaticseparator without disassembly; the technical problem of backwashing of a packing is insufficient, the backwashing efficiency is low, and the packing is difficult to dry in the prior art are solved. The electrostatic separator comprises a cylinder body; a plurality of packing plates are arranged among an electrode column, an inner electrode and the cylinder body which are coaxial, each packing plate is provided with an assembly column insertion hole, a fixed column insertion hole, a movable column insertion hole, an electrode hole and a packing placement hole, packing is arranged on the packingplates, odd-numbered plates are fixed through fixed columns, and horizontal movement of even-numbered plates is controlled through movable columns to change the packing stacking mode.

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...
