Description
Technical field
The utility model relates to slag treatment fields in industrial processes, and in particular to a kind of furnace slag granulating system.
Background technique
Current yellow phosphorus electric furnace slag water quenching technique mainly includes the water quenching of slag bath nature and high-order slag storehouse dewatering process.This two
The characteristics of kind technique is that clinker gravity flow enters slag bath and water phase meets progress water quenching.Water Quenching Slag natural sediment in slag bath bottom, via
It grabs slag driving to pull out, until low level slag storehouse carries out nature draining.The process flow is simpler, and high-temperature slag falls into slag of quenching during this
It is careless and sloppy that a large amount of slag vapour are generated when pond, slag vapour main component is water vapour, containing other pernicious gases such as micro hydrofluoric acid.It causes serious
Visual pollution and atmosphere pollution (belong to uncontrollable discharge).Scene and periphery operator's body are damaged, and to surrounding
Mechanical equipment causes heavy corrosion, influences the normal use and service life of equipment.Major part yellow phosphorus enterprise is not to certainly at present
The slag bath progress of right water quenching effectively covering closing and slag gas collect emission treatment, and (note: quench slag and fishing slag process are that intermittence is grasped
Make).
Phosphorus production enterprise in part has put into substantial contribution and has carried out upgrading to phosphorus furnace slag system of quenching at present, will be original
Slag bath remove be changed to granulation tower slag tap+dewatering drum filtering+belt muck haulage to the mode in slag storehouse carry out slag vapour collection processing.This
Kind of reforming mode to it is original quench slag technique and the change of slag bath frame it is larger, put into a large amount of electromechanical equipment, automatic control, monitoring etc. and set
It is standby.Dewatering drum strainer is easily stifled, and the screen replacing period is shorter.Overall Reconstruction expense and operating cost are higher, only a small amount of yellow phosphorus
Manufacturing enterprise adopts.And the transformation period is long, is affected to phosphorus production.
Some yellow phosphorus enterprises then use simple steel deck-plate+hinge and carry out enclosing covering to slag bath, seal when slagging tap to slag bath
Lid raises steel deck-plate when fishing out slag again.Although investment is smaller, steel deck-plate is more heavy and is influenced to be easy by high temperature near cinder notch
Deformation leads to serious steam leakage with slag bath pool wall without effective sealing, fails the root problem for thoroughly solving leakage vapour undiscipline.
Part creates phosphorus production slag bath and collects slag cigarette vapour of quenching, Ke Yiyou using slag bath+collecting hood of tipping bucket type at present
Effect by fume collection.But the shallower item for not having transformation tipping bucket type slag bath of the original depth of slag bath of most of phosphorus production enterprise
Part becomes the very crux of many phosphorus production environmental protection of enterprise upgradings.
