Abstract

The invention relates to the technical field of coke ovens, in particular to a coal tar modification and coke oven carbonization chamber top coke prevention method and system.The method comprises the following steps: water vapor is introduced into a coke oven carbonization chamber top, the temperature of the coke oven carbonization chamber top is controlled to be 800-1400 DEG C, raw coke oven gas at the coke oven carbonization chamber top reacts with coke oven gas or primary raw coke oven gas introduced into the coke oven carbonization chamber top under the participation of the water vapor, the raw gas cracking depth and strength are effectively controlled, raw gas coal tar macromolecules are modified and lightened, the coke prevention effect on the top of a coke oven carbonization chamber is better achieved, the advantage of higher coke prevention reaction kinetics is achieved, the principle of modification of water molecules and the raw gas macromolecules is utilized, according to the method, the anti-coking and light-weight coal tar modification motive power is enhanced. According to the method disclosed by the invention, the coking time and the whole coke oven production period are greatly shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coke ovens, in particular to a method and system for modifying coal tar and preventing coking at the top of a carbonization chamber of a coke oven. Background technique [0002] In the coking process, the coking coal is heated and dry-distilled in the coke oven to generate coke. At the same time, a large amount of raw gas is produced. Under the action of high temperature, some macromolecular hydrocarbons will be cracked into methane, and the methane will continue to be affected by the high temperature. Cracks to release free carbon and hydrogen. Free carbon is easily attached to the coke oven roof of the exhaust gas, and then forms a graphite layer that is firmly bonded to the brick. As for how to remove graphite, Chinese patent 2021103469073 discloses a method and system for coal tar modification and coking prevention at the top of the coke oven carbonization chamber. The cooling gas is fed to the top o...
