Embodiment 1
[0033] like figure 1 and figure 2 As shown, an oil shale dry distillation semi-coke dry coking device includes an oil shale dry distillation furnace 1, including a cooling quenching and waste heat recovery unit, a furnace body continuous coke unloading unit and an oil shale dry distillation semi-coke exporting unit, Oil shale retorting furnace 1, cooling coke quenching and waste heat recovery unit, furnace body continuous coke unloading unit and oil shale retorting semi-coke exporting unit are sequentially connected from top to bottom; the cooling quenching and waste heat recovery unit includes water wall 2 and the economizer 3, the oil shale retort 1, the water wall 2 and the economizer 3 are connected in sequence from top to bottom; the continuous coke unloading unit of the furnace body includes a coke guide groove 4, a coke pusher 5, a coke tray 6 and the coke collecting bin 7, the economizer 3, the coke guide groove 4 and the coke collecting bin 7 are connected in sequen...
Embodiment 2
[0035] like figure 1 and figure 2 As shown, an oil shale dry distillation semi-coke dry coking device includes an oil shale dry distillation furnace 1, including a cooling quenching and waste heat recovery unit, a furnace body continuous coke unloading unit and an oil shale dry distillation semi-coke exporting unit, Oil shale retorting furnace 1, cooling coke quenching and waste heat recovery unit, furnace body continuous coke unloading unit and oil shale retorting semi-coke exporting unit are sequentially connected from top to bottom; the cooling quenching and waste heat recovery unit includes water wall 2 and the economizer 3, the oil shale retort 1, the water wall 2 and the economizer 3 are connected in sequence from top to bottom; the continuous coke unloading unit of the furnace body includes a coke guide groove 4, a coke pusher 5, a coke tray 6 and the coke collecting bin 7, the economizer 3, the coke guide groove 4 and the coke collecting bin 7 are connected in sequen...
Embodiment 3
[0038] The oil shale retort furnace 1 is connected to the water-cooled wall 2 by welding, and the water-cooled wall 2 and the economizer 3 are connected by welding. The oil shale retort furnace 1 is connected with the water wall 2 by welding to prevent the leakage of dry distillation gas; the structure of the water wall 1 matches the coke discharge port of the oil shale retort furnace 1, and can be square (applicable when the coke discharge port is a square shape. upright retort furnace) or circular (suitable for the upright retort furnace with a circular coke discharge port); the water wall 2 and the economizer 3 are welded and connected to jointly cool the oil shale retort semi-coke, cool down the coke, quench the coke and recover the waste heat. , the water wall 2 is used to produce high-quality steam, the economizer 3 is used to preheat the boiler feed water, and the oil shale dry distillation semi-coke is cooled after passing through the inner cavity of the two.
