Abstract

The invention relates to the field of metallurgical equipment mounting, in particular to a method for mounting a dry quenching circulating fan. The method sequentially comprises the following steps of: (a) basically checking and accepting; (b) setting foundation bolts and a seat slurry pier device as well as opening a box to check equipment; (c) mounting a fan, a bearing and a motor base; (d) carrying out primary grouting of the foundation bolts of the equipment; (e) mounting a lower bearing block; (f) mounting a lower shell of the fan; (g) mounting a rotor; (h) mounting an upper bearing casecover, an upper slip and a shaft seal; (i) mounting an upper shell of the fan and a shaft seal; (j) mounting the motor; (k) correcting a coupling; (l) mounting an adjustment and execution mechanism of the inlet and the outlet of the fan; (m) carrying out secondary grouting on an equipment foundation; (n) mounting expansion joints of the inlet and the outlet; (o) mounting a circulating cooling water system and an accessory system; and (p) carrying out test run of the equipment. Through strictly designing normative mounting and detecting standards, the invention has the advantages of simple debugging method, safety, reliability and high working efficiency.

Description

technical field [0001] The invention relates to the field of metallurgical equipment installation, in particular to a method for installing a CDQ circulation fan. 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 quenching technology is a ...
