Luxing patent technology of lime hydration line
Quick lime (CaO) is transported into Buffer Tank (1) by Belt Conveyor, then the Uniform
Device (3) evenly delivery the raw material (CaO) averagely 1-30 tons per hour into Fine Crusher
(4), crusher can crush massive material into under 10mm.
During the crushing process the generating dust, which is from pipe on the cover of Buffer Tank
and pipe on the cover of the end of Uniform Device, will come into the Pulse Bag Filter (2). (This is
the first stage of environmental treatment to prevent dust escape.)
The fine crushed quick lime fall into the entrance of Bucket Elevator (5), then it is elevated and
transported into Raw Material Silo(6).
On the body of silo, there is installed an Up and Down Material Level Indicator which will send
instructions to PLC Control System when material is overfilled or insufficient. On the top of the silo
there is installed a Top Position Duster (7) of which function is to prevent lime dust escaped when
air in the silo is extruded by feed-in material ( This is second environmental treatment.)
The quick lime falls into Screw Feeder (9) through Electric Gate Valve, where is transported
into Screw Electronic Weighing Machine (10), according to one hour consumption (a series from
one to thirty tons per hour), quick lime is fed into Three-stage Hydrator (11) to be hydrated with
proportional water.
At first the quick lime in the hydrator is pushed into the first stage silo by a length of screw, of
which function is prevent a mass of overheated vapor mixes with lime dust counter flow into Screw
ElectronicWeighing Machine where will impact the accuracy of sensing signal. By many adjusting
means of frequency converter, adjustable weir and so on, we can control the quick lime in the three
stage hydrator to be hydrated for 8-12 minutes for an enough hydration.
Unique design makes massive heat generated in the lime hydration course recycled, which is to
increase the material temperature in lime hydration for enough hydration. On the top of the hydrator,
here we set up a Dust Cage, in which there are three pieces of sprinklers, they can spray three pieces
of water surface to prevent massive of overheated vapor and lime dust generating in the lime
hydration course (this dust is good quality hydrated lime, should be recycled.) escaped. This is to
lessen the dust capacity in next progress.(The third environmental treatment.)
When the lime dust escaped from the water surface comes into Wet Scrubber through pipe.
(also known as Dust Removal Device, which is our patent product, Patent No.
ZL200110133877.8)(22) Massive of lime dust and overheated vapor, which is quick lime generating
in three stage hydrator, comes into water tank through dust cage and pipeline. In the wet scrubber
lime dust is filtered in the water by negative pressure generated by fan. After treating the dust and
vapor, the purified air will finally be exhausted on the air vent. In the process of treating dust and
overheated vapor, the water in the water tank of wet scrubber comes into being hot lime water, which
is injected into water pipe used for water surface by high-pressure pump.
The wet scrubber achieves to recycle the hot dust removal water and its collection coefficient
can reach to more than 99%. Dust removal effect is that the dustiness is less than 30 milligram per
cubic meter on the air vent. (Our state standard: dustiness is 150 mg/m3 )
Finally we can achieve energy saving and effect enhance and solve environmental pollution
problem of dust flying.
The hydrated lime (water content is 1.5%) falls into Screw Feeder (12) and is transported to
Bucket Elevator (15), then it is elevated into Centrifugal Separator: T-sepax efficient two section
separation which use aerodynamics analytical method, adopt two stage separation to divide the
material to coarse particle and fine particle.
In the first graduated area, it pre-separates the coarse particle of the mixed powder into coarse
powder heap, then, the second graduated area is a accurate separation which is completed in the
annular region consist of guide vane and cage rotor.
Thanks to the pre-separation of separating the coarse particle, therefore, classifying precision is
higher, and the powder-selecting efficiency can reach to 92%.
The different grades of separated material powder separately falls into Screw Feeder (18),
comes into Bucket Elevator (19), elevated into Product Silo (20). The hydrated lime is controlled
by Electric Gate Valve to be packed by Bagging Machine in storage.
