Abstract
The utility model relates to a limekiln especially relates to a two thorax kiln. A two thorax kilns with inner skleeve hang an inner skleeve between third area kiln shell bottom and the second area kiln shell, is forming annular space between inner skleeve and the second area stove outer covering, the inner skleeve bottom is equipped with the round and holds in the palm the brick. The utility model discloses the annular space that forms can carry out the heat exchange, and the annular space is difficult for the deposition.
Description
Technical field
This utility model relates to limekiln, particularly relates to a kind of double thorax kiln.
Background technology
In the industry of limekiln, BASK and double thorax kiln are more advanced two kind kiln types, are provided with upper and lower inner core in sleeve lime kiln, and inner core and kiln shell are concentric circular.So between inner core and kiln shell, defining an equidistant annular space, this is also the reason that sleeve kiln is referred to as annular lime kiln.In sleeve kiln structure, the inner space of whole kiln body is separated to form annular space by inner sleeve, and on the one hand inner sleeve serves the supporting role passing a bridge upper and lower two-layer；On the other hand be internally formed circulation gas channel in kiln body, for formed gas circulation channel and realize raw material limestone and flow calcine technology architecture basics be provided.
Additionally, have been put in the double thorax kilns used also having the double set kiln of corbel type at home, i.e. and flow end of tape and bracket (bracket is in circumferentially spaced-apart layout) is set supports the structure of its end so that it is structure stress reaches stably.But circumferentially disposed bracket makes the annular space formed in the 2nd band kiln shell be easy to when producing causes dust stratification dross, as cleared up not in time, local temperature herein can be caused to raise, resistance to material in region and structure are caused damage, deashing work have to be carried out frequently by the gray moving hole on top, adding operational risk and workload to daily production, this is also one of the shortcoming of the double thorax kiln of corbel type.
Summary of the invention
This utility model is intended to overcome the defect of prior art, it is provided that a kind of double thorax kilns with inner sleeve.The annular space that this utility model is formed can carry out heat exchange, and annular space is difficult to dust stratification.
In order to solve above-mentioned technical problem, a kind of double thorax kilns with inner sleeve, suspended on an inner sleeve bottom described 3rd band kiln shell and between the 3rd band kiln shell, form the space of annular between inner sleeve and the second band furnace shell, bottom described inner sleeve, be provided with a circle torr brick.
Described a kind of double thorax kilns with inner sleeve, described inner sleeve is sandwich cavity structure, logical cold wind in cavity.
This utility model is according to the version of double-hearth lime kiln kiln shell, inner sleeve is arranged between the second band kiln shell and the 3rd band kiln shell, inner sleeve is suspended on bottom the 3rd band kiln shell, is not provided with bracket and supports bottom inner sleeve, realizes being reliably connected with the 3rd band and the second band kiln shell.The space of annular is defined between the inner sleeve and the second band furnace shell that hang.Inner sleeve external diameter is about 5084mm, and height is 2770mm, and it is internal is sandwich cavity structure, can be aerated cooling.The function that the inner sleeve arranged can realize is as follows:
1, inner sleeve is suspended on bottom the 3rd band kiln shell, length that is that extend double-hearth lime kiln and that flow burning zone so that the heat that limekiln fuel combustion produces sufficiently is utilized；
2, the annular space formed between inner sleeve and the second band kiln shell makes the cooling wind in kiln bottom portion and the steam on top enter another kiln thorax after carrying out sufficient heat exchange in circular passage, preheats kiln thorax；The annular space formed can carry out heat exchange, and annular space is difficult to dust stratification；
3, in " Duckbill type " structure of the bottom of inner sleeve, it is functionally similar to the torr brick circle of resistance to material, subjects the weight of the top brick of resistance to material；
4, hanging inner sleeve is sandwich, and one side cooling wind can enter interlayer and structure carries out cooling down, and the steam on the other hand flowed out from interlayer can be directly entered combustion air pipeline and use as combustion air, it is achieved that pre-heat utilization, reduces heat consumption.
Accompanying drawing explanation
Below, in conjunction with accompanying drawing, this utility model is further described:
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of double thorax kilns with inner sleeve of this utility model, suspended on an inner sleeve 1 bottom described 3rd band kiln shell 3 and between the second band kiln shell 2, form the space of annular between inner sleeve and the second band furnace shell, bottom described inner sleeve, be provided with a circle torr brick 4.
Described a kind of double thorax kilns with inner sleeve, described inner sleeve is sandwich cavity structure, logical cold wind in cavity.
Claims (2)
1. the double thorax kilns with inner sleeve, it is characterised in that suspended on an inner sleeve bottom the 3rd band kiln shell and between the second band kiln shell, form the space of annular, are provided with a circle torr brick bottom described inner sleeve between inner sleeve and the second band furnace shell.
A kind of double thorax kilns with inner sleeve the most according to claim 1, it is characterised in that described inner sleeve is sandwich cavity structure, logical cold wind in cavity.
