Abstract
The utility model discloses an energy-saving lime kiln, which comprises a raw material input opening, a combustion area, a cooling area and a discharging opening. The combustion area is provided with a combustion beam; three or four layers of combustion beams are arranged inside the combustion area; a fuel pipeline, a combustion-supporting air pipeline and a cooling media layer are arranged inside a beam body of each combustion beam; outlets of the fuel pipeline and the combustion supporting pipe are connected to a burner on the lateral wall or at the bottom of each beam body; a wear resistant heat preservation layer is arranged on the whole outer surface of each beam body except for the burner; and the cross section of each beam body of the combustion beam is an inverted trapezoid with an wide upper portion and a narrow lower portion, thereby the design not only can effectively prevent influence of external high temperature, but also can reduce collision to the lateral wall of the beam bodies of raw materials in descending process, and further achieves the effect of increasing service life of the combustion beam.
Description
Technical field
The utility model relates to a kind of limestone kiln.
Background technology
During with the beam-type limekiln calcined limestone, raw materials such as Wingdale are added installing in the limestone kiln from the top, raw material is from top to down through preheating district, calcining zone, cooling zone, then from the products export output.Be provided with burning beam in the calcining zone, burning beam is the nucleus equipment of beam-type limekiln, and its cross section is generally the cavity structure of rectangle or T type, is loaded with combustion agent and heat-eliminating medium in the cavity.The beam body of burning beam is provided with burner, fuel conduit and combustion air pipeline, fuel conduit and combustion-aid air pipe road direction burner fuel supplying and combustion air, and burner uniform distribution fuel also burns.
In order to prevent burning beam, in burning beam, also be provided with the interior media cooling line usually because of high temperature oxidation.Under hot conditions, though burning beam has interior media circulation cooling, the burning beam surface is still oxidized easily, ablate, and causes dielectric leakage and loses efficacy.And in the filler process, the raw material major part is a bulk in irregular shape, must produce very big washing away to the sidewall of burning beam when raw material falls, wearing and tearing will inevitably cause the damage of burning beam sidewall for a long time, thereby cause the leakage of heat-eliminating medium even combustion agent.Be generally at present two-layerly at the burning beam of calcining zone, the calcining zone height is spent low, if by the operation of ordinary production speed, Wingdale decomposes fully and just leaves calcining zone, promptly can occur giving birth to burning phenomenon; Burn if will avoid giving birth to, have to reduce travelling speed and be forced to the underproduction.Some owner is in order to reach product, and raising kiln travelling speed is had to strengthen combustion gas and air feed rate again simultaneously, thereby caused heat distribution inhomogeneous, and burning appears near the lime the burner, and lime at a distance still has part to give birth to burning.
The utility model content
The utility model technical issues that need to address provide the limestone kiln of a kind of efficient energy-saving, raising product burning quality.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of energy-saving lime kiln comprises the raw material input aperture, preheats the district, calcining zone, cooling zone and discharge port that calcining zone is provided with burning beam, and described burning beam is the multilayer setting.
Improvement of the present utility model is: described burning beam is three layers or four layers.
Further improvement of the utility model is: have a burning beam on described every layer of burning beam at least.
The improvement of described burning beam is: be provided with fuel conduit, combustion air pipeline and heat-eliminating medium layer in the beam body of described burning beam, the outlet meet of the outlet of fuel conduit and combustion-supporting pipeline is connected with burner, it is characterized in that: the entire exterior surface of described beam body is removed the burner place, is provided with one deck heat resistant and wear resistant thermofin.
The further improvement of described burning beam is: the cross section of described beam body is wide at the top and narrow at the bottom trapezoidal.
The improvement of described burning beam also is: described burning beam is a T type beam, and described T type beam is made up of crossbeam and beam body, and the termination, both sides of crossbeam is fillet.
Owing to adopted technique scheme, the obtained technical progress of the utility model is:
When burning beam of the present utility model is set to three layers or four layers, adjust the ratio of combustion air and fuel simultaneously, make the burning of burner even, can guarantee that not only the limestone kiln is to reach the operation of product speed, raw material is decomposed fully, give birth to and burn and the reduction of burning rate, thus the quality of assurance product, make that efficiency of combustion increases, output increases, and further improves the utilization ratio and the working efficiency in limestone kiln.Its outside surface is removed the heat resistant and wear resistant thermofin advantage that the burner place all is provided with and is: (1) is because the thermofin thermal conductivity is very little, the internal-external temperature difference of thermofin is bigger, the burning beam surface temperature is lower, and it is less to pass to the heat of burning beam cooling oil, and the energy consumption of kiln is reduced.Raw material directly washed away Liang Bi when (2) wear-resisting thermofin can also prevent to add the dress raw material in the limestone kiln.The cross section of burning beam is set to down ladder beam or two ends are the T of falling trapezoid type beam for the fillet bottom, all can effectively prevent in the descending process of raw material collision to the beam body sidewall, and the termination, both sides of T type beam is set to fillet also can make burner place, both sides be heated evenly, and then reaches the raising burning beam effect in work-ing life.
