Novel limestone kiln

Technical field

The utility model relates to the texture improvement of industrial furnace, particularly relates to a kind of novel limestone kiln.

Background technology

The formation condition of lime be with lime carbonate after continuing insulation for some time under the temperature condition about 1100 degree, elements such as the carbon in the lime carbonate, phosphorus burning totally back forms.What old-fashioned limestone kiln was comparatively common has two kinds, and a kind of is to have mixed coal to light in the cartridge type kiln and fire, and the lime that burns out needs artificial screening, and this mode had both consumed coal resource, had polluted environment, and labour cost also is a huge expense; Another kind of limestone kiln is to utilize mechanical means to drive the rotating disk of filling lime carbonate, interrupted baking realizes the formation of lime under rotating disk, this mode also is comparatively advanced now technology, but, the shortcoming of this method clearly, the lime carbonate that promptly just has been heated leaves the heating zone by rotating disk and just begins to cool down, and the lime inclusion content that this method is produced is bigger, and the lime quality of producing is not high enough.Continue heating if use instead, the energy of consumption is but comparatively huge, and very likely excessive burning ripe lime baking.

In sum, old-fashioned limestone kiln has following shortcoming:

1. energy consumption is serious, no matter be coal or electrically heated, all has the waste of the energy.

2. the starting material that general lime is fired all need be through screening, and size needs consistent, could on average be heated like this.

3. the lime produced of cartridge type limestone kiln is also wanted artificial screening, and electrically heated limestone kiln is to the having relatively high expectations of machinery, and the quality of product is not easy control very much.

Summary of the invention

The purpose of this utility model just is to overcome the defective of above-mentioned prior art, and a kind of energy utilization rate height is provided, consume little, pollution-free, and output height, the novel limestone kiln of good product quality.

The utility model is achieved through the following technical solutions:

A kind of novel limestone kiln, comprise body of heater and be connected chimney on the body of heater exhanst gas outlet, it is characterized in that: be provided with many rows in the described body of heater by top vertical forge batch can and the on every side reciprocally arrayed heating quirk the thereof straight-through end of to, wherein at least two vertical bottoms of forging batch can are communicated as one;

The origin of heat of described heating quirk is in being installed in the other process furnace of body of heater;

Described body of heater smoke outlet is equipped with dust removal installation;

The top layer of above-mentioned heating quirk with forge batch can and communicate.

Limestone kiln of the present utility model has following technical characterstic:

1. the utility model utilizes process furnace that thermal source is provided, and heating raw is a cinder, blows afloat perfect combustion in burner hearth through high-pressure air, has promptly avoided energy dissipation, has effectively utilized waste and old resource, has avoided environmental pollution again.

2. limestone kiln of the present utility model adopts the structure formation of multilayer quirk multiple tank body, the quirk arrangement that becomes to turn back, such structure can only flow heat with a direction, by coming from the suction of chimney, chimney is high more, the suction that produces is also just strong more, and strong suction makes heat mobile in proper order at each interlayer, and is dispersed in the tank body; Quirk is clipped in tank body therebetween layer by layer simultaneously, make material heat in quirk from top to bottom in the process of flowing continuous high temperature heating chemical reaction takes place, with Impurity removals such as wherein carbon, phosphorus, and under the pyritous condition, carry out catalysis, 70%～80% change into lime during to discharging.This mode can make material fully absorb heat, improves the utilization ratio of heat energy.

3. because material lime carbonate volume in the process that transforms can become big, so the utility model is combined into an integral body with at least two bottoms of forging batch can, following tank body space is increased, there is sufficient space to satisfy the volumetric expansion of lime, provides guarantee for improving output and device security, normal operation.

4. the top layer quirk communicates with forging batch can in the utility model limestone kiln, can absorb the heat energy that the material spontaneous combustion produces like this, and effectively save energy improves efficiency of energy utilization.

5. exhanst gas outlet of the present utility model is equipped with dust removal installation, has avoided environmental pollution.

In sum, limestone kiln of the present utility model has the energy utilization rate height, consumes for a short time, and environmental pollution is little, and the output height, the quality product advantages of higher.

Embodiment

As shown in Figure 1 and Figure 2, limestone kiln of the present utility model comprises a rectangular parallelepiped body of heater 1, and body of heater 1 has two-layer: outer is the brick layer, and internal layer is a thermal insulation layer, and the thermal insulation layer ecto-entad is made up of insulating brick, refractory brick and insulation asbestos plate successively.Be provided with in the body of heater 1 two row or multi-row by the top straight-through the end of to forge batch can 4, forging around the batch can 4 is heating quirk 5.Above-mentioned heating quirk 5 is that the quirk of turning back is more than five layers, is generally five to 13 layers, decides as required by the formed quirk of turning back of being interspersed of horizontal baffle 8; The top layer of heating quirk 5 with forge batch can 4 and communicate; Heating quirk 5 bottoms have gas approach 9 and exhanst gas outlet 2, and gas approach 9 is connected with process furnace 6, and exhanst gas outlet 2 is connected with chimney 3, and exhanst gas outlet 2 places are equipped with dust removal installation 7.Above-mentioned at least two bottoms of forging batch can 4 are for to be communicated as one: promptly establish a crossbeam 11 in the bottom of body of

heater

1,5 of the heating quirks of forging between the batch can 4 are established top, support with the cycloidal arch 12 that is installed on the crossbeam 11 then, can make at least two bottoms of forging batch can 4 in aggregates like this, thereby increase the volume of lower tank.In the lower end of forging batch can 4 discharge bucket 10 is installed.

During operation, at first batch can is suitable for reading to be gone into to forge in the batch can tank body with the raw material lifting and from forging with lift technique, both sides and intermediary quirk toast the raw material in the tank body under the mobile heat, because the heat in the quirk is a mobile from top to bottom, so temperature also is to have top to bottm to descend step by step, the temperature of the superiors is about 1100 degree, this moment, the heating to lime carbonate also just began, continuous interpolation along with raw material, lime carbonate enters the tank body middle part downwards and continues insulation, the temperature of quirk is about 800 degree at this moment, and continue lime carbonate is heated, it is also the most thorough that lime carbonate conversion is at this moment carried out, because lime carbonate volume in the process that transforms can become greatly, so be the shunting tank body on the upper strata of limestone kiln, middle by crossbeam as support, the tank body of lower floor is integrated, following tank body space is increased, have sufficient space to satisfy the volumetric expansion of lime.Burn 7～8 sophisticated lime and discharge tank body, need not screen, can pack shipping when equitemperature is suitable with discharge bucket.
