Abstract
The utility model is a kind of limekiln body structure, main body is rectangle, there is ash inlet on top, there is ash output hole bottom, set gradually in kiln that horizontal kiln gas extracts pipe out from top to bottom, horizontal upper strata burns the lower floor of chewing beam and transverse direction and burn and chew beam, upper strata is burnt and is chewed beam and lower floor and burn and chew beam inside and be all provided with multiple burner; It is Wingdale reserve zone that ash inlet and kiln gas are extracted out between pipe, and kiln gas is extracted pipe and upper strata out and burnt and chew for preheating zone between beam, and upper strata is burnt and chewed beam and lower floor and burn that to chew between beam be calcining zone, and lower floor burns that to chew between beam and ash output hole be cooling zone.Compared with prior art, the utility model is provided with twice burning and chews beam, effectively by the heat evenly distribute of kiln body inside, can ensure calcining effect.
Description
Technical field
The utility model belongs to chemical machinery field, is more specifically to provide a kind of limekiln body structure.
Background technology
Limestone kiln is used to calcined limestone, generates the kiln of unslaked lime.Its technological process is, Wingdale and fuel start to decompose to 850 degree after loading limestone kiln (if geseous fuel is sent into through pipeline and burner) preheating, complete calcining, then after cooling, unload outside kiln discharge to 1200 degree.Namely the production of unslaked lime product is completed.Different kiln shapes has different preheatings, calcining, cools and unload grey mode.But have some technological principle to be namely identical: raw materials quality is high, lime quality is good; Fuel value is high, and quantity consumption is few; Limestone granularity and calcination time are directly proportional; Unslaked lime activity degree and calcination time, calcining temperature is inversely proportional to.
Limestone kiln is primarily of compositions such as kiln body, feeding device, distribution device, combustion unit, ash-discharging device, electrical equipment, instrument control device, cleaning apparatuss.Multi-form limestone kiln, its structure formation and calcinated form are distinguished to some extent, and technical process is substantially identical, but apparatus value has very large difference.
All there is the problem of uneven heating in current kiln body, the efficiency of serious restriction lime production and quality.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of limekiln body structure.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of limekiln body structure, main body is rectangle, there is ash inlet 1 on top, there is ash output hole 9 bottom, set gradually in kiln that horizontal kiln gas extracts pipe 6 out from top to bottom, horizontal upper strata burns the lower floor of chewing beam 7 and transverse direction and burn and chew beam 8, upper strata is burnt and is chewed beam 7 and lower floor and burn and chew beam 8 inside and be all provided with multiple burner.
It is Wingdale reserve zone 2 that ash inlet 1 and kiln gas are extracted out between pipe 6, and kiln gas is extracted pipe 6 and upper strata out and burnt that to chew between beam 7 be preheating zone 3, and upper strata is burnt and chewed beam 7 and lower floor and burn that to chew between beam 8 be calcining zone 4, and lower floor burns that to chew between beam 8 and ash output hole 9 be cooling zone 5.
Compared with prior art, the utility model is provided with twice burning and chews beam, effectively by the heat evenly distribute of kiln body inside, can ensure calcining effect.
Accompanying drawing explanation
Accompanying drawing is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further details.
As shown in drawings, the utility model is a kind of limekiln body structure, main body is rectangle, there is ash inlet 1 on top, there is ash output hole 9 bottom, set gradually in kiln that horizontal kiln gas extracts pipe 6 out from top to bottom, horizontal upper strata burns the lower floor of chewing beam 7 and transverse direction and burn and chew beam 8, upper strata is burnt and is chewed beam 7 and lower floor and burn and chew beam 8 inside and be all provided with multiple burner.
It is Wingdale reserve zone 2 that ash inlet 1 and kiln gas are extracted out between pipe 6, and kiln gas is extracted pipe 6 and upper strata out and burnt that to chew between beam 7 be preheating zone 3, and upper strata is burnt and chewed beam 7 and lower floor and burn that to chew between beam 8 be calcining zone 4, and lower floor burns that to chew between beam 8 and ash output hole 9 be cooling zone 5.
Working process of the present utility model is as follows:
Wingdale is entered Wingdale reserve zone 2 by the ash inlet 1 on kiln body top, then after preheating, calcining zone 4 is entered into, under upper strata burning chews beam 7 and lower floor's burning chews the acting in conjunction of beam 8, heat is divided evenly, the scope of multiple spot heat supply is made to cover the whole cross section in limestone kiln, ensure that by regulating the partition ratio of each burner heat supply is even, ensures efficiency of combustion by adjusting air-fuel ratio.Thus ensure that the raw burning rate of lime and high activity degree.Kiln gas is extracted out pipe 6 by the opening that kiln gas is extracted out on pipe 6 by kiln gas and is extracted out, ensures that the negative pressure in whole cross section in kiln is evenly distributed, makes the air flow method in this kiln whole section of face all even smooth and easy, keep best combustion effect and minimum fuel consumption.
What more than introduce is only based on preferred embodiment of the present utility model, can not limit scope of the present utility model with this.Any the replacement of parts well know in the art, combination, discrete is done to the utility model, and do equivalent change well know in the art or replace all not exceed protection domain of the present utility model to the utility model implementation step.
