Rotary Activated Furnace:
Rotary activated carbon activation furnace, continuous feeding, continuous discharging, superheated steam evenly distributed to the furnace, reacting with carbon particles, generating water gas, burning atmosphere up to 800-900, through interval ablation of carbon holes and tar combustion removal, to achieve the purpose of hole-making and opening. Surplus gas from by-products is sent to steam boiler as fuel, and steam is supplied to activate the furnace to form a cycle. This kind of activation furnace has the advantages of large capacity, low energy consumption, high yield, easy regulation and control, uniform activation degree of products, methylene blue and iodine adsorption value higher than 20% of the standard index, and stable production of high-quality products. The capacity of a single activation furnace ranges from 500 t/a to 5000 t/a. There are many types of rotary activated carbon steam activation furnace with different capacity.
Rotary activation furnace is an internally heated fluidized bed continuous production activation furnace. The activator is water vapor and flue gas. This method is also used in the production of wood charcoal.
Rotary Activated Stove
When the rotary activation furnace works, the carbide is added to the top hopper, and the feeding device feeds the carbide into the furnace quantitatively and continuously. Driven by the reducer of the stoker, the gear meshing makes the burden layer on the furnace bed be constantly turned over, the temperature of the carbide is constantly rising, the furnace body has a tilt during installation. With the rotation of the furnace body, the carbide material moves gradually to the middle of the furnace under the driving of its own gravity and inertia, and then again. Move intermediate to end outlet. Repeated this way, the material moves slowly from top to bottom, and the activated carbon is activated by the moving process and through the steam, and discharged from the tail outlet. The temperature of each section can be adjusted through combustion. The flue gas of combustion products and the water vapor from the inlet of water vapor in the furnace wall move up and down in the opposite direction to the material, and contact with the material countercurrent for activation, and eventually discharge from the flue gas outlet of the furnace top. The furnace wall is also provided with an air inlet, from which a certain amount of air is injected into the furnace, and the combustible gas produced by the activation process of water supply steam and carbon materials is fully burned and used, and the activation temperature is maintained. The residence time (activation time) of the activated carbon material in the furnace is controlled by the frequency converter to adjust the speed of the motor. The equipment uses high temperature tail gas to drive the waste heat boiler to produce steam for activation, without adding any fuel.
