The invention provides an activating furnace system with an independent hot blast furnace. The activating furnace system comprises a vertical type heating furnace discharging opening, a lower thermocouple, an upper thermocouple, a feeding opening, a discharging opening, an automatic heating device, a manual valve, an electric valve, a flow meter, an electric heating band and the hot blast furnacein a cuboid shape. The vertical type heating furnace discharging opening is located in the bottom of a cylinder-shaped heating furnace. The feeding opening is located in the top end of the cylinder-shaped heating furnace. The side face of the upper portion of the cylinder-shaped heating furnace is provided with the discharging opening. The automatic heating device is wound around the side face ofthe cylinder-shaped heating furnace, and the exterior is provided with a heat preserving layer. Pipelines arranged in parallel in the longitudinal direction are arranged in the hot blast furnace in the cuboid shape. The side face of the hot blast furnace in the cuboid shape is provided with the electric heating band. The activating furnace system has the beneficial effects that the activating furnace system is designed to be a closed container in the whole, the bottom and the top are controlled to be opened through valves, normal-pressure or pressure-keeping heating operation can be carried out, the system is flexible, and is innovative in the field of catalyst preparation from the function and the structure, and the equipment cost is saved.
