Background technique
In the prebaked anode green body production process of electrolytic aluminium, kneading, cooling, molding can all generate bitumen flue gas, especially
Kneading process has a large amount of flue gas discharges, drip in kneading pot mouth and discharge gate since kneading temperature is greater than pitch softening temperature
Containing multiple pollutants such as glance coal, flue dust, S02 in green flue gas, while flue-gas temperature is extremely unstable, and this flue gas operating condition is to drip
The various purification methods of green cigarette have different degrees of influence.Currently, the glance coal purification side studied and applied both at home and abroad
Method has: combustion method, absorption process, absorption method and electric fishing method, and each manufacturer uses different modes and is dusted to bitumen flue gas
Reach environment protecting with collecting, although producing certain effect, due to the distinctive property of asphalt smoke itself, such as viscosity
Big adhesive force is strong, dust is big, temperature is high, is extremely difficult to ideal effect, often will cause equipment, dust deposited in pipeline blocking, not only
Environmental protection and energy saving effect is not had, environmental requirement is not achieved, or even also will cause secondary pollution.This secondary pollution in order to prevent,
Patent 201210554204 proposes the purification method and device of a kind of bitumen flue gas, the source that the purpose is to generate from glance coal
It is adsorbed, but because the smoke density of kneading pot discharge is big and temperature is extremely unstable, is added after the cooling of cold oil device
Quick setting, it is easy to be bonded in inside glance coal branch pipe, to gradually cause branch blockage.
Summary of the invention
The purpose of this utility model is to propose a kind of glance coal purification system suitable for prebaked anode kneading pot, using thin
Particle coke powder carries out multiple spot and dusts adsorption technology, makees adsorption treatment in the source that bitumen flue gas generates, reduces glance coal in pipeline
The interior residence time avoids pipeline pitch binder applied, prevents line clogging, makes the flue gas emission meet the requirement of environmental protection of kneading pot.
The utility model uses a kind of following technical scheme: glance coal purification system suitable for prebaked anode kneading pot,
Including the kneading pot exhaust fume collecting hood being set to above kneading pot and the conveyer seal closure being set to below kneading pot discharge gate, conveying
Secret sealing cover is connected to discharge gate below kneading pot, and kneading pot exhaust fume collecting hood top, conveyer seal closure top have been respectively communicated with cigarette
Gas branch pipe is provided with dusting device in each flue gas branch pipe, and each dusting device passes through powder supply pipeline respectively and is connected to coke powder storehouse, respectively
Flue gas branch pipe is connected to flue gas supervisor, and flue gas supervisor end is connected to deduster, and deduster arranges the dust particles being collected into
It puts to circulation feed bin, processed gas is emitted into atmosphere by deduster by main air blower；The dusting device is by literary mound
In pipe and high pressure blower constitute, Venturi air arrival end is connected to high pressure blower, Venturi tube negative pressure arrival end and powder supply
Pipeline connection, Venturi exit end is axially aligned to be provided with uniformly distributed radial spray orifice.
The Venturi tube and flue gas branch pipe are coaxial.
The axis of each radial spray orifice of the Venturi tube is obliquely installed, and aperture inclined direction goes out with Venturi tube
Mouth end is in the same direction.
The principles of the present invention: according to Venturi tube principle, and the angle tilt setting that will dust, be conducive to drip when dusting
Green flue gas rises, and shortens time of the bitumen flue gas in flue gas branch pipe, and dedusting dress can be quickly entered after coke powder granular absorption
It sets and is handled.
The beneficial effects of the utility model are: changing traditional glance coal trapping and processing mode, generated in bitumen flue gas
Source carry out adsorption treatment, reduce residence time of the glance coal in pipeline, improve adsorption effect, reduce pipeline pitch binder applied
Cigarette prevents the blocking of pipeline；Powder after completing glance coal absorption can periodically, quantitatively enter production system and be recycled benefit again
With.
