The utility model discloses a design is unique, and the material evenly falls to the production of reducible " kiln wall effect ", the life in extension limekiln burns the calcium carbonate gauge height that, active good.
Description
Technical field
The utility model belongs to lime production field devices, particularly environmental protection limestone kiln.
Background technology
In the production of lime, kiln body is the main reaction vessel of Wingdale, limestone kiln is in the past in order to build conveniently, generally build as vertical barrel type, after raw material after being pulverized enters kiln body, can not get disperseing timely, cloth is uneven, thin and thick is inconsistent, in calcination process, will calcine insufficient or calcination time is long, cause raw burn or the burning of lime, raw material contacts with straight tube kiln wall, form kiln wall effect, calcine insufficient, cause waste, and wear and tear kiln wall, greatly reduces the work-ing life of kiln body.
Summary of the invention
Technical assignment of the present utility model provides a kind of novel environment friendly limestone kiln for above prior art deficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of novel environment friendly limestone kiln, comprise Preblend system PBS, feeding system, apparatus for distributing, kiln body calcination system and discharge system and relevant automatic Controlling System, described Preblend system PBS comprises coal stone hopper, vibratory screening apparatus and batch mixing belt, feeding system comprises feeding cart and material loading skew bridge, apparatus for distributing refers to revolving top, the internal diameter of described limestone kiln body expands from top to bottom gradually, in toroidal, be beneficial to the even drop down of material, and the generation of " kiln wall effect " can be reduced, kiln body upper inside wall installs wear-resisting steel plate additional, raw material is very light to the wearing and tearing of kiln wall, extend the work-ing life in limestone kiln, described kiln body calcination system refers to that limestone kiln is along being divided into three sections highly from top to bottom, i.e. preheating zone, calcining zone and cooling zone, the loss of kiln body heat is little, energy-conserving and environment-protective, coefficient of heat utilization is high, and contribute to the steady running of lime calcining process, effectively prevent the generation of partially burning phenomenon, described discharge system is arranged on below kiln body, between be provided with and unload the continuous ash discharge of grey car.
The design of this utility model is unique, and the even drop down of material, and the generation that can reduce " kiln wall effect " extend the work-ing life in limestone kiln, burns the lime quality high, active good.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
Embodiment
With reference to Figure of description, the utility model is described in detail below:
As shown in Figure 1, a kind of novel environment friendly limestone kiln, comprise Preblend system PBS, feeding system, apparatus for distributing, kiln body calcination system and discharge system and relevant automatic Controlling System, described Preblend system PBS comprises coal stone hopper 1, vibratory screening apparatus 9 and batch mixing belt 8, feeding system comprises feeding cart 10 and material loading skew bridge 2, apparatus for distributing refers to revolving top 3, be transported in kiln rotary-top distributor 3 through material loading skew bridge 2 in Wingdale and coal cinder loading feeding cart 10, distributor is inner at kiln body by material cloth uniformly, the internal diameter of described limestone kiln body expands from top to bottom gradually, in toroidal, be beneficial to the even drop down of material, and the generation of " kiln wall effect " can be reduced, kiln body upper inside wall installs wear-resisting steel plate additional, raw material is very light to the wearing and tearing of kiln wall, extend the work-ing life in limestone kiln, described kiln body calcination system refers to that limestone kiln is along being divided into three sections highly from top to bottom, i.e. preheating zone 4, calcining zone 5 and cooling zone 6, according to the difference of Wingdale in the esoteric physicochemical change of kiln, its concrete reaction process is:
Preheating zone 4: on kiln body top, temperature range is 90 1 850 DEG C; Flue gas and Wingdale carry out heat exchange;
Calcining zone 5: in the middle part of kiln body, temperature range is 1000-l200 DEG C, and all chemical reactions carry out at this;
Cooling zone 6: in kiln body bottom, temperature range is 850 1 80 DEG C, and lime and freezing air carry out heat exchange.
Kiln body heat loss under this kind of embodiment is little, and energy-conserving and environment-protective, coefficient of heat utilization is high, and contributes to lime calcining process and obtain steady running, effectively prevents the generation of partially burning phenomenon.
Described ash discharging system 7 is arranged on below kiln body, between be provided with and unload the continuous ash discharge of grey car.
The relative position in each district is certain above, but it highly can change.The principal element affecting each district height is that whether Wingdale and coke size be even and whether size is suitable.When operating normal, the general proportions that each district accounts for furnace chamber cumulative volume is: preheating zone 25%, calcining zone 50%, cooling zone 25%.Lime is transported to star-like soot blower through unloading grey car by the lime through cooling, and lime is delivered to ash discharge belt and completes ash discharge process by planetary ash hoist.
Claims (2)
