Description

technical field [0001] The invention relates to the field of installation of metallurgical alarm devices, in particular to an installation method for an automatic CDQ fire alarm system. Background technique [0002] Dry coke quenching is a newly born smelting energy-saving technology in the world. Its English name is Coke Dry Quenching, or CDQ for short. CDQ uses circulating inert gas as the heat carrier, and the circulating fan sends the cold circulating gas into the red coke cooling chamber to cool the high-temperature coke to below 250°C and discharge it. The circulating hot gas after absorbing the heat of coke is introduced into the waste heat boiler to recover heat and generate steam. After the circulating gas is cooled and dedusted, it returns to the cooling room through the fan, so that the red coke is cooled in this way. The steam generated by the CDQ boiler is either integrated into the steam pipe network in the plant or sent to generate electricity. Dry coke que...
