Problems solved by technology

It can be seen that the working system of the full CDQ process system causes each set of CDQ equipment to operate within the range of 60% to 70% of the design capacity most of the time, which is not only a waste of equipment resources, but also causes equipment Increased investment costs, in addition, long-term low-load operation will cause damage to the boiler system

Abstract

The invention relates to a system and a method for realizing stable and high yield of dry quenching steam. The system comprises a dry quenching system, an air forced blowing system and a combustible gas supply distribution system, the air forced blowing system comprises a forced air blower and a main air blowing pipeline; the combustible gas supply and distribution system comprises a combustible gas main pipeline, a combustible gas branch pipeline and a combustible gas distributor; the influence of dry quenching system faults or coke oven overhaul and maintenance on the dry quenching steam yield can be effectively eliminated, and the dry quenching steam yield is stabilized and improved; in addition, the problem of equipment investment waste caused by low operation load of a single set of dry quenching equipment when a full dry quenching process is adopted can be solved, and meanwhile, damage possibly caused by long-time low-load operation of a dry quenching boiler is avoided.

Description

technical field [0001] The invention relates to the technical field of coke dry quenching, in particular to a system and method for realizing stable and high production of coke dry quenching steam. Background technique [0002] The production process of the conventional CDQ system is as follows: figure 1 As shown, the red-hot high-temperature coke is loaded into the CDQ furnace 1 from the top entrance of the CDQ furnace through a mechanical lifting device, and is in countercurrent contact with the inert circulating gas V1 blasted from the bottom of the CDQ furnace 1 to exchange heat. The discharge from the bottom of the CDQ furnace 1 completes the dry coke quenching, and the inert circulating gas V2 heated to 900-1000°C contains a large amount of coke powder and is discharged from the outlet of the annular air duct of the CDQ furnace 1 into the gravity sedimentation dust collector 2. In the gravity settling dust collector 2, large particles of coke powder are deposited and ...
