The operation of dust pelletizing system interior arrangement described in the utility model is also therewith by corresponding loop cycle operation.It coalingging, flat coal, plucking furnace
Before door coke pushing movement starts, the dedusting fan 7 in system is run at high speed by low speed steering；(contain tar particles in flue dust
The flue dust of equal stickums) enter before dust pelletizing system, powder active regeneration and blowing integrated apparatus 3 start, and will be preliminarily sprayed
Powder, which is sent into sack cleaner 1, reaches high-effective dust-removing in cloth bag surface formation powder spray coating to remove sticky microparticle
Purpose；Powder is preliminarily sprayed because having bonded the sticky microparticle such as part tar after participating in dust removal process, partial size becomes larger, surface is lost
Drying, mushy feature have been gone, it can not direct reuse；Processing can only be exported by conventional way, then to pre- spray
What supplement was new in painting filler bin is preliminarily sprayed powder；And powder active regeneration described in the utility model and blowing 3 energy of integrated apparatus
It is enough to realize that the activating and regenerating that powder is preliminarily sprayed, the dust that sack cleaner receives 1 collection are sent into powder active regeneration and blowing integration
After device 3, it is heated to 250~300 DEG C inside evaporator 303, glues the sticky microparticle such as tar being mixed in dust at this time
It decomposes, gasify at high temperature, to make dust activity recovery, then be stored in storage ash cellar after regenerative powder cooling device is cooling
In 307, it can be re-used as and powder use is preliminarily sprayed；The utility model can also be realized in dust pelletizing system is preliminarily sprayed powder
Automatic addition, clout are sent outside, spraying, output quantity are adjusted and be recycled automatically, powder are preliminarily sprayed without external complement, to protect
Dust pelletizing system reliability of operation and long-time stability have been demonstrate,proved, artificial labor intensity is alleviated.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
