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.

This invention is a kind of new-type vertical continuous coke oven, and a high-temperature dry distillation coking device of coal. The main characteristic of this invention is: After the cool furnace roof holds the coal, are urged to fall by the jar of hydraulic pressure of the furnt device, arrange the burnt device, list while being cool by stove bottom finally, dry distillation coal gas a part that course produce melt down and heat, the others support downstream production need; Air after preheating by heat exchanger, is it set up by oblique way fire dish mix burning with coal gas to enter, the high-temperautre waste gas after burning is discharged by the horizontal passway of the waste gas in the top of combustion chamber, retrieve heat energy for the power plant of remaining energy.
