Description
Affiliated technical field
The present invention relates to a kind of kiln body of wall safeguard construction of accommodate thermal expansion, especially a kind of wall body structure that is mainly used in kilns such as natural gas cross flame metallurgic auxiliary materials tank furnace.
Background technology
The kiln burning is the second largest power consumption industry that present domestic energy consumption is only second to boiler combustion; In recent years; Along with rising steadily of fuel price; The continuous improvement of enterprise's Workshop Production environment, this just requires as the kiln of heat fused unit heat to be fully used, and reduces the peripherad heat radiation loss in furnace wall.
The present domestic kiln wall body structure that a lot of types are also arranged, still from the situation of present application, various forms of kiln wall body structures have its weak point.In view of the situation, the present invention proposes and adopt multi-level kiln body of wall safeguard construction, the material structure of four kinds of different levels of utilization has fundamentally solved the outwards problem of a large amount of heat radiations of kiln furnace wall, can reduce the consumption of fuel simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of under the prerequisite that equal fuel consumes; More heat is utilized effectively, and can reduce the kiln furnace wall outwards the wall body structure of heat radiation to solve problems such as kiln body of wall thermal loss of the prior art is big, energy consumption height.
In order to reach the foregoing invention purpose; Technical scheme of the present invention is to realize like this; The kiln body of wall safeguard construction that this is multi-level comprises the fire brick layer that is used to isolate flame interaction that outwards sets gradually from kiln body of wall inwall, further stops first thermal insulation layer to external diffusion, prevents the air heat insulating layer of heat transmission and stop flowing and playing the second heat insulation structural layer of firm body of wall effect of heat-insulation layer air pass to heat on the fire brick layer from kiln inside; The wall body structure outermost also is provided with the column that adapts to wall body structure expansion usefulness, on column, whenever is provided with adjusting screw(rod) at a distance from a segment distance, and the front end of adjusting screw(rod) contacts with the outer wall of the second heat insulation structural layer, and the structure of column is detachable steel frame construction.
Wherein, the material of fire brick layer is the high-temperature flame-proof fused cast refractories, and the material of first thermal insulation layer is the alumina silicate heat-barrier material, and the material of air heat insulating layer is a mineral wool, and the material of the second heat insulation structural layer is the diatomite lightweight thermal insulation brick.Specifically, high-temperature flame-proof fused cast refractories layer is positioned at the innermost layer of kiln body of wall, directly bears the inner high temperature of kiln; The alumina silicate thermal insulation layer is positioned at the outside of high-temperature flame-proof fused cast refractories layer; Stop the heat that passes to from kiln inside on the high-temperature flame-proof fused cast refractories it to external diffusion, the mineral wool air heat insulating layer is positioned at the outside of alumina silicate thermal insulation layer, and the thermal conductivity factor of mineral wool air heat insulating layer is well below brick body material; Thereby prevented the transmission of heat to greatest extent; Diatomite lightweight thermal insulation brick layer is positioned at the outside of mineral wool air heat insulating layer, plays firm body of wall, and the effect that stops mineral wool air heat insulating layer air to flow.
The invention has the beneficial effects as follows:
(1) this multi-level kiln body of wall safeguard construction makes the heat insulation and preservation effect of kiln body of wall strengthen greatly, reduces the kiln furnace wall and outwards dispels the heat, and under the prerequisite that equal fuel consumes, more heat is utilized effectively.
(2) this multi-level kiln body of wall safeguard construction has reduced the kiln furnace wall and has outwards dispelled the heat, and has reduced the environment temperature in workshop, and the production environment in enterprise workshop is greatly improved.
(3) this multi-level kiln body of wall safeguard construction makes the expansion of kiln body of wall very little.Simultaneously, in order further to guarantee the safety of wall body structure, be provided with the column of band adjusting screw(rod), the body of wall of microdilatancy has been played certain support bearing effect, guaranteed that the long-life of kiln body of wall uses in wall outer side.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a kiln body of wall safeguard construction sketch map of the present invention;
Among the figure
1 fire brick layer, 4 second heat insulation structural layers
