Description
Technical field
The utility model is related to powdery active lime production technical field, specially a kind of powdery with flameholding system
Active lime suspension roaster.
Background technology
In recent years, in terms of active lime has become the high new material application such as iron powder sintering, light building material, chemical
One important foundation inorganic non-metallic material, with social economy, the development of environmental improvement, market demand sharply increases；
Currently, traditional lime production technique mainly be applied to metallurgy industry, be used to produce grain size 20mm or more blocky stone
Ash, and the source of powdered lime is obtained by the blocky lime produced is carried out grinding, but existing powdered lime system
It is standby to cannot achieve large-scale production, it is difficult to meet market drastically widened demand, and be limited by traditional handicraft, powdered lime exists
The serious waste of 35% or more limestone resource can be caused in preparation；Meanwhile the kiln for being traditionally used for lime production can only fit
For the production of blocky lime, belong to the heating of accumulation state, heat exchange, rate of heat transfer is small, and the thermal efficiency is low, enters stove to stone from lime stone
Ash products, which are come out of the stove, usually requires 6 hours even longer time courses, and the daily output of single set equipment be difficult to realize kiloton with
On large-scale production, production efficiency is relatively low, preheating be difficult to recycle, be not used to the suspension roasting technique of powdered lime；
In addition, in the existing suspension calcining technique for powdery active lime, it is 150 that can not utilize fineness still
The lime stone powder raw material of ~ 350 mesh directly produces the suspension roaster of powdery active lime；The work of suspension theory is used at present
Industry kiln is widely used in clinker production system, i.e. dore furnace, the heat from grate-cooler in clinker production system
The high-temperature flue gas of wind and rotary kiln tail portion provides thermal stable condition for the stable operation of the dore furnace.In powdery active lime
The combustion air temperature from cooling system is relatively low in suspension roaster, generally within the scope of 450 ~ 600 DEG C, normally no higher than
600 DEG C, and the decomposition temperature of limestone calcium carbonate is generally between 650 ~ 950 DEG C, and in roaster limestone calcium carbonate point
Solution belongs to the endothermic reaction, and consumption of calorie is more, while material is in suspended state heat transfer in roaster and heat exchange efficiency is very high, heat
Amount consumption is quick, in addition the influence of fuel burning point and burn rate, is difficult to for a long time to easily lead to thermal regulation in roaster
Holding continuous-stable, can cause to stop working in stove when serious to stop production etc. seriously affects the technology accident of production, especially in system
Harmful effect when larger fluctuation occur in igniting initial start stage and blanking can be more serious；
In conclusion since the lime of domestic existing lime technology production is mainly blocky lime, i.e., at present still without phase
The equipment answered can be used for directly production powdery active lime, meanwhile, come in powdery active lime suspension roasting system self cooling
But the hot blast temperature of system is much lower, and hot blast temperature is unstable, especially in system igniting initial start stage, in no hot wind
Under conditions of, ignition operation is extremely difficult, can be great once there is unusual condition during entire roasting system is run
Influence production.
Invention content
The purpose of this utility model is to provide a kind of powdery active lime suspension roaster with flameholding system, with
Solve the problems mentioned above in the background art.
To achieve the above object, the utility model provides the following technical solutions：
A kind of powdery active lime suspension roaster with flameholding system, including roasting furnace body, the roaster

Air compartment, the air compartment are connected with wind turbine.
Preferably, the lower end of the roasting furnace body is truncated cone-shaped structure.
Preferably, the inner wall of the roasting furnace body is covered with refractory insulating layer.
Preferably, the thickness of the refractory insulating layer is more than five centimetres.
Compared with prior art, the utility model has the beneficial effects that：This powdery active lime with flameholding system
Suspension roaster is simple in structure, and the raw material being preheated enter from feed pipe, and fuel is fed in fluid bed, and raw material mix simultaneously with fuel
It is cracked, subsequently enters the burning of fluid bed upper space, cooling system hot-air is increased to work through flameholding system temperature
Enter roaster ontology after the requirement temperature of condition, ensures that roasting furnace body fuel smoothly stablizes burning, to make roaster sheet
Body temperature field keeps stable and uniform, stabilized product quality；Pass through the theory analysis and powdered lime to decomposition of limestone process
The research of suspension roasting mechanism, the powdery active lime suspension roaster provided by the utility model with flameholding system can
Continuous operation steady in a long-term is not only able to meet to ensure the stable operation of powdery active lime suspension roasting system
The needs of powdery active lime suspension roasting, and it can use fuel same as roaster；
This powdery active lime suspension roaster with flameholding system is mainly used for producing using suspension roasting method
The production system of powdery active lime, going into operation, igniting is out-of-date, can be improved from cooling system by flameholding system
