[0005] The device adopts the air supply form combining the air supply from the outside to the inside by the peripheral air ring and the air supply from the inside to the outside of the central air cap from the upper part of the furnace body. The uniform distribution in the circumferential direction is conducive to the uniform cooling of the coke in the furnace and improves the cooling performance of the CDQ furnace; however, the fine control of the cooling method of the CDQ furnace is still not achieved, especially the independent adjustment of the local temperature of the CDQ furnace cannot be realized and control

The invention relates to a multi-air-flue automatic air supply adjusting system and method for a coke dry quenching boiler. Cooling air entering each independent upper air chamber exchanges heat with coke in the coke dry quenching boiler through a corresponding annular air flue in the mode of flowing from the periphery to the center; one part of cooling air entering each independent lower air chamber reaches the middle of the coke dry quenching boiler through a center air supply flue, perpendicularly enters a center air cap upwards, and enters the coke dry quenching boiler from the center air cap in the mode of flowing from the center to the periphery to exchange heat with coke, and the other part of cooling air reaches the middle of the coke dry quenching boiler through a middle air supply flue, perpendicularly enters a middle air cap upwards, and enters the coke dry quenching boiler from the middle air cap in the mode of flowing from the middle to the periphery to exchange heat with coke; temperature field signals in the coke dry quenching boiler are collected through a thermal infrared imager and converted into images to be displayed on a control system display screen, the supply air rate of each air flue of the coke dry quenching boiler is adjusted by controlling an air control device at each position, cold recycle air entering the coke dry quenching boiler is evenly distributed in the boiler, and coke in the boiler is evenly cooled.
Description
technical field [0001] The invention relates to the technical field of dry quenching coke, in particular to a system and method for automatic adjustment of gas supply in a multi-air channel of a dry quenching furnace. Background technique [0002] The air supply devices for CDQ running in China include 75t / h, 140t / h, 190t / h and above air supply devices for CDQ, and most of the air supply devices are cross air ducts or straight air ducts. The reasons for the uneven cooling of coke in the CDQ furnace are analyzed, which are mainly caused by the uneven particle size distribution of the coke, the uneven distribution of the coke falling speed and the uneven distribution of the air flow on the cross section of the entire CDQ furnace. [0003] The air supply device installed at the bottom of the CDQ has a great influence on the uniformity of coke falling and the uniformity of airflow distribution in the CDQ. If its structure is conducive to the uniform drop of coke in the furnace ...
