Title:
METHOD AND SYSTEM FOR REUSING FLUE GAS OF CIRCULAR COOLER, AND CIRCULAR COOLER
Document Type and Number:
WIPO Patent Application WO/2010/057439
Kind Code:
A1
Abstract:
A method for reusing flue gas of circular cooler comprises the steps of collecting middle temperature flue gas discharged from a middle temperature region Ⅱ of a circular cooler (30) as cooling wind in a high temperature region Ⅰ of the circular cooler (30), and then collecting high temperature flue gas discharged from a high temperature region Ⅰ for reuse. A system for reusing flue gas of circular cooler comprises a circular cooler’s hood, which is arranged above the flue gas exhaust pipeline in the middle temperature region Ⅱ of the circular cooler (30) and used for collecting the flue gas, a front wind pipe (32) and a back wind pipe (31) which are respectively communicated with the circular cooler’s hood and the cooling wind pipe (35) in the high temperature region Ⅰ of the circular cooler (30), and a circulating fan (33) which is mounted between the front wind pipe (32) and the back wind pipe (31). A circular cooler collects middle temperature flue gas discharged from a middle temperature region Ⅱ of a circular cooler (30), and the part of the middle temperature flue gas is used as the cooling wind in a high temperature region Ⅰ of the circular cooler (30). After the middle temperature flue gas self with a certain temperature heat exchanging with high-temperature materials, it discharges high temperature flue gas with very high temperature, and then the part of high temperature flue gas is collected and reused for generating electricity, boiling water, and the like, thus effectively improving the efficiency of the flue gas reuse.
