Abrégé

A pulverized coal coking equipment, comprising a pulverized coal semi-coking and pyrolyzing furnace (1); the pyrolyzing furnace comprises from top to bottom respectively a furnace charge inlet (2), a feeding and distributing area (3), a coal gas collection area (4), a coal gas dust filtration zone (5), a coal gas dispersion area (7), a pulverized coal pyrolyzing area (8) and a cooling coke discharging area (9). Also provided is a coking method utilizing the pulverized coal coking equipment, the method employing the pulverized coal with a particle diameter of less than 20mm, and comprising the steps of: spreading the charge, preheating, dust filtering, pulverized coal pyrolyzing, coal gas collecting and coke discharging. Using the pulverized coals with the particle diameter of less than 20mm for coking ensures that the pulverized coal pyrolysis is balanced, the coal gas generated during pyrolysis can be smoothly discharged, and the tar produced is clean and dust-free. The present invention utilizes ascending hot coal gas to preheat the pulverized coal, and descending semi-coke to preheat cold air and coal gas, thus fully utilizing heat energy, saving energy and reducing emission.
