The utility model discloses both avoid the raise dust phenomenon, carried out recycle to the dust again, improved electrolytic manganese slag's utilization ratio.
Description
Technical field
This utility model belongs to electrolytic manganese waste residue calcining production line technology field, and it is a kind of right to be specifically related to
The dust produced in calcination process carries out the fume recovery system reclaimed.
Background technology
Electrolytic manganese waste residue is the industrial residue of discharge in electrolytic manganese smelt production, and its character is
The viscosity cake of the moisture content about 27%-28% that 90 mesh fine powders are formed.Electrolytic manganese waste residue contains
Substantial amounts of building materials desired substance, the electrolytic manganese waste residue after high-temperature calcination can replace natural stone
Cream, desulfurated plaster are as the retarder of cement, it is also possible to be ground being processed into superfine again and be allocated as
For the external feeding of commerical ready-mixed concrete, replace super finely ground slag, flyash etc..Electrolytic manganese waste residue is in calcining
During constantly evaporate due to moisture, substantial amounts of dust can be produced, workers with long time is operated in dust ring
In border, easily suffering from pneumoconiosis, serious harm is healthy.
Utility model content
The purpose of this utility model is to provide a kind of dust for electrolytic manganese waste residue calcining production line
Recovery system, it is possible to reclaim the dust produced in calcination process and re-start calcining, it is to avoid airborne dust
Phenomenon.
For achieving the above object, this utility model be the technical scheme is that a kind of for
The fume recovery system of electrolytic manganese waste residue calcining production line, including for calcining returning of electrolytic manganese waste residue
Rotary kiln and batch bin, material is delivered in rotary kiln by described batch bin by conveyer, including rotation
Wind cleaner unit, sack cleaner, air-introduced machine and blender；The air inlet of described cyclone dust extractor,
Air vent is connected with the exhaust port of rotary kiln, the air inlet of sack cleaner respectively；Described cloth
The air vent of bag dust collector is connected with the air inlet of described air-introduced machine；Described cyclone dust extractor and cloth bag
The ash discharging hole of cleaner unit is connected with blender by closed conduit respectively；The discharging opening of described blender
Connected with described batch bin by closed conduit；It is provided with spray equipment in described blender.
This utility model has the advantages that the tail gas in rotary kiln can be inhaled by air-introduced machine successively
Entering in cyclone dust extractor, sack cleaner, cyclone dust extractor is suitable for purifying the dust more than 5 microns,
Can tentatively remove the big dust particle in tail gas, sack cleaner can be removed in tail gas further
The dust of fine particle, good dedusting effect, and alleviate the work load of sack cleaner, have
Help the service life of extension device.Air-introduced machine is arranged at the floss hole of sack cleaner, it is possible to
Avoid air-introduced machine to be directly sucked in the tail gas containing dust, thus avoid dust granules that air-introduced machine is caused
Abrasion and blocking.Dust is stirred machine to carry out adding water re-forming after stirring and has certain water content
Electrolytic manganese waste residue, and being stored in batch bin, then forge in being re-fed into rotary kiln by conveyer
Burn, both avoided dust raising phenomenon, and again dust had been recycled, and improve electrolytic manganese waste residue
Utilization rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of fume recovery system for electrolytic manganese waste residue calcining production line,
Including rotary kiln 1 and batch bin 6 for calcining electrolytic manganese waste residue, described batch bin 6 is by defeated
Sending machine 7 to be delivered to by material in rotary kiln 1, described conveyer 7 is conveying worm, is suitable for defeated
Send tool sticking electrolytic manganese waste residue.Also include cyclone dust extractor 2, sack cleaner 3, air inducing
Machine 4 and blender 8, the air vent of described air-introduced machine 4 connects air accumulator 5 or titanium dioxide
Sulfur absorption tower, containing sulfur dioxide gas and ammonia in the tail gas of dust removal process, it is impossible to directly
Discharge, is stored by air accumulator 5 or sulfur dioxide absorbing tower carries out desulfurization process, it is to avoid cause big
Gas pollutes.The air inlet of described cyclone dust extractor 2, air vent are arranged with the tail gas of rotary kiln 1 respectively
Put mouth, the air inlet of sack cleaner 3 is connected；The air vent of described sack cleaner 3 is with described
The air inlet of air-introduced machine 4 is connected；Described cyclone dust extractor 2 divides with the ash discharging hole of sack cleaner 3
Tong Guo not be connected with blender 8 by closed conduit；The discharging opening of described blender 8 passes through closed conduit
Connect with described batch bin 6, the process of circulation of dust is all carried out in closed conduit, it is to avoid raise
Dirt phenomenon.Being provided with spray equipment in described blender 8, the stirring container of described blender 8 is envelope
Enclosed mixing drum, described spray equipment is the seedpod of the lotus spray being arranged on described Hermetical stirring cylinder top
Head, the spray area of seedpod of the lotus shower nozzle is relatively big, and water outlet is uniform, makes stirring function that water is uniform with dust
Mix and blend.
The running of technique scheme is as follows: the tail gas in rotary kiln is inhaled by air-introduced machine 4 successively
Entering in cyclone dust extractor 2, sack cleaner 3, big dust particle tentatively removed by cyclone dust extractor 2
After, sack cleaner 3 carry out again final dusting remove fine dusts, the tail gas after udst separation from
The air vent of air-introduced machine 4 enters in air accumulator 5 or sulfur dioxide absorbing tower；Cyclone dust extractor 2 with
The dust collected in sack cleaner 3 then enters in blender 8 from respective ash discharging hole, through stirring
Mix machine 8 to add water to be formed after stirring there is the electrolytic manganese waste residue of certain water content, be re-fed into batch bin 6
In, conveyer calcine in being re-fed into rotary kiln 1.
