Description
Technical field
The present invention relates to a kind of dolomite shaft furnace dust pelletizing system.
Background technology
Light dolomite is the mineral material that dolomite mineral processes through uniform temperature roasting, and its mechanical strength is little, and chemism is high, and the porosity is large, and structure dredges structure, in an atmosphere very easily aquation, can be used for steel-making and spatters slag.Dolomite mineral, in roasting process, can produce very large harmful smoke, and lot of domestic and international enterprise adopts multi-tube dust cleaner purifying smoke to dolomite shaft furnace.More and more stricter along with controlling the requirement of atmosphere pollution, the efficiency of dust collection of multi-tube dust cleaner can not meet the requirement of environmental protection, therefore, needs to treat technological transformation to multi-tube dust cleaner is anxious.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of dolomite shaft furnace dust pelletizing system, the present invention can improve efficiency of dust collection effectively.
Technical scheme of the present invention is as follows:
Dolomite shaft furnace dust pelletizing system, comprise discharging machine, charging hoister, diffusing chimney, cyclone dust collectors, sack cleaner, blower fan, aiutage and conveying worm, the output of discharging machine is connected with the input of charging hoister, the output of charging hoister is connected with the input of diffusing chimney, the output of diffusing chimney is connected with the input of cyclone dust collectors, the output of cyclone dust collectors is connected with the input of sack cleaner, the output of sack cleaner is connected with the input of blower fan, the output of blower fan is connected with the input of aiutage, the ash discharging hole of described cyclone dust collectors and sack cleaner is communicated with conveying worm respectively.
Also comprise bucket elevator and storage ash-pit, the input of bucket elevator is connected with conveying worm by pipeline, and the output of bucket elevator is connected with storage ash-pit by pipeline.
Have employed such scheme, because the white dynamic stone chemism after calcination is high, and the porosity is large, structure dredges structure, very easily aquation in an atmosphere, therefore, have employed cyclone dust collectors and sack cleaner two kinds of dry collectors carry out dedusting successively in the present invention, the temperature that effect due to cyclone dust collectors can make waste gas obtain must reduce, thus avoids sack cleaner Yin Wendu too high and have influence on efficiency of dust collection.After the effect of two-step filter, the dust of removing arrives conveying worm by ash discharging hole, then delivers to bucket elevator by conveying worm, by bucket elevator, dust is delivered to storage ash-pit, is finally transported by slag-soil truck.In addition, under the effect at blower fan of the waste gas of dedusting, guide to aiutage, discharged by aiutage.Because the present invention is by the combination of cyclone dust collectors and sack cleaner, not by the impact of EGT, this improves efficiency of dust collection.
