Abstract
The invention relates to an energy saving environmental protection electrode baking furnace and a treating method of roasting asphalt smoke. A plurality of furnace chambers with the same structure is linked in series to form a system. The furnace chambers can be both communicated and cut off through a flue and a flue valve. When the electrode baking furnace is being baked, the asphalt smoke which is produced from a low temperature furnace chamber and is in a volatilization stage is burned for the first time on a self combustion port. The residual incompletely burned asphalt smoke goes into a ring-shaped flue under the effect of negative pressure draught and is induced into another flue of a high temperature furnace chamber through a regulating valve. The asphalt smoke is fully burned for the second time at a combustion port. The completely burned waste gas goes into a straight discharge flue through a central flue of the high temperature furnace chamber. With dusts and tars eliminated in a purifying system, the flue gas is discharged into atmosphere through a chimney. The invention can make the hydrocarbon fuel gas burned completely, solve the asphalt smoke pollution on the atmosphere effectively, make full sue of energy and lower the treatment cost.
