The invention discloses a
microwave pretreatment desulfurization coking device, and particularly provides a device for coking
coal. The device comprises a
coal blending process, a
coal charging process and a coking process; and the method further comprises a
microwave pretreatment process between the
coal blending process and the coal charging process. The
microwave pretreatment process adopts a microwave pretreatment device with the
microwave frequency ranged from 300MHz to 300GHz for irradiating,
dewatering and desulfurizing the blended coal; and the temperature of the pretreated coal sample is controlled between 150 and 250 DEG C; and then coal is prepared to be charged into a stove and coked. The microwave pretreatment device comprises a microwave
reaction chamber body, a connecting device, a conveyor, an exhaust duct and a detection
control system, wherein the connecting device, the conveyor, the exhaust duct and the detection
control system are arranged among the microwave
reaction chamber body, a
coke stove coal
tower and a coal charging trolley or a material bin. The device is simple; after being quickly preheated, dewatered and desulfurized, the blended coal can be coked so as to improve the
bulk density, shorten the coking time and promote the yield of a single furnace as well as the coal quality; and clean and effective utilization of energy can be realized.
