According to the device and the method, the dust removal efficiency is improved and the device is convenient to assemble and maintain.

Description

technical field [0001] The invention belongs to the field of petroleum coke calcination, and in particular relates to a dedusting device for calcining coke and a dedusting method thereof. Background technique [0002] In calcined coke, the vacuum residue of petroleum is cracked and coked at 500-550°C by a coking device to produce black solid coke. Its appearance is a black or dark gray honeycomb structure, and the pores in the coke block are mostly oval and interpenetrating; according to the difference in sulfur content, it can be divided into high-sulfur coke (sulfur content above 3%) and low-sulfur coke (sulfur coke) content below 3%). [0003] A large amount of dust will be produced in calcined coke, and the International Organization for Standardization stipulates that suspended solids with a particle size of less than 75 μm are defined as dust. The existence of dust in the atmosphere is one of the main reasons to keep the temperature of the earth, and too much or too ...

AI Technical Summary

Problems solved by technology

The existence of dust in the atmosphere is one of the main reasons to keep the temperature of the earth, and too much or too little dust in the atmosphere will have a disastrous impact on the environment; therefore dust removal is required, and the prior art generally removes dust by dust collectors, but The filter area of ​​the existing dust removal device is small, which leads to low dust removal efficiency;
