Description
Technical field
The utility model belongs to preheating furnace technical field, especially relates to a kind of preheating furnace protecting wall structure of insulation.
Background technology
Preheating furnace can be used for substituting high-grade fuel by after the high-temperature calcination of low inferior fuel processing; Its process is mainly by low inferior fuel (mainly referring to blast furnace gas, heating gas, the low calorie fuels such as tail gas) or air, through heat exchanger, heat exchange in the high-temperature flue gas of heating furnace, improves low inferior fuel or air themperature, general to 300-900 degree; Thus improve the actual combustion temperature of inferior fuel or the sensible heat of air.
Therefore preheating furnace produce time its inside and outside the temperature difference larger, lightweight in order to reach refractory material in present production technology, housing carrying is light, and can ensure again the requirement of serviceability while reducing costs, conventional protecting wall structure is the composite construction of lining lightweight thermal insulation brick and ceramic fibre material.Although this structure has good heat-proof quality, this structure needs thicker liner thickness could meet lining Design requirement, while meeting heat insulating effect, when production capacity is fixed, needs to increase housing, adds cost; Simultaneously when furnace operation temperature is higher, need to increase liner thickness guarantee huyashi-chuuka (cold chinese-style noodles) outside wall temperature and reach designing requirement.But the equipment of some limited space or position, select conventional ceramic fibre material and lightweight heat-proof brick structure, huyashi-chuuka (cold chinese-style noodles) outside wall temperature is too high, cannot meet industrial furnace designing requirement.
Utility model content
For above-mentioned problem, the purpose of this utility model is, provides a kind of structure simple, can meet the preheating furnace protecting wall structure of warming demand in high temperature difference situation inside and outside furnace wall when wall thickness is thinner.
The utility model solves the technical scheme that its technical problem adopts: this preheating furnace protecting wall structure comprises outer wall shell, fibrolamellar, heat insulation brick layer from outside to inside successively; Described fibrolamellar from outside to inside, be disposed with three-decker, be designed with micropore thermal baffle layer between wherein said second layer fiberboard and the third layer fiberboard of innermost layer, the gross thickness of this preheating furnace furnace wall is 280mm-320mm, and the thickness of described micropore thermal insulation board is 20mm-30mm.
As preferably, described micropore thermal baffle layer uses nano material to make.
As preferably, described heat insulation brick layer uses double-decker.
As preferably, described heat insulation brick layer is be greater than with the inner layer heat-insulation brick density of contact raw in preheating furnace the insulating brick being wrapped in its outside in double-decker.
The beneficial effects of the utility model are: the high temperature raw material of preheating furnace inside is passed a layer thermal insulation by sandwich construction by this preheating furnace protecting wall structure, most thermostable heat insulation brick layer is placed on internal layer, high temperature resistant poor fibre board material is placed on skin, make the cooling structure of furnace wall more reasonable like this, the use of micropore thermal baffle layer substantially increases the heat insulation effect of preheating furnace, effectively can improve the thickness of furnace wall, reduce the volume of preheating furnace entirety, huyashi-chuuka (cold chinese-style noodles) outside wall temperature is reduced greatly, reach industrial furnace designing requirement, structure is more reasonable.
Accompanying drawing explanation
Fig. 1 is the structural representation in preheating furnace protecting wall structure cross section.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
As shown in the embodiment shown in fig, this preheating furnace protecting wall structure mainly uses when manufacturing preheating furnace, and it comprises outer wall shell 1, fibrolamellar 2, heat insulation brick layer 3 from outside to inside successively; Described fibrolamellar 2 from outside to inside, be disposed with three-decker, the fibrolamellar of multilayer can prevent because the damage of one deck fiberboard, and in the excessive loss of local temperature, seam crossing simultaneously between the every Rotating fields of described fibrolamellar 2 can be crisscross arranged, and heat can be prevented like this in the excessive loss of seam crossing.Be designed with micropore thermal baffle layer 4 between wherein said second layer fiberboard and the third layer fiberboard of innermost layer, the gross thickness of this preheating furnace furnace wall is 280mm-320mm, and the thickness of described micropore thermal insulation board 4 is 20mm-30mm.
The high temperature raw material of preheating furnace inside is passed a layer thermal insulation by sandwich construction by this preheating furnace protecting wall structure, most thermostable heat insulation brick layer 3 is placed on internal layer, high temperature resistant poor fibre board material is placed on skin, make the cooling structure of furnace wall more reasonable like this, the use of micropore thermal baffle layer 4 substantially increases the heat insulation effect of preheating furnace, effectively can improve the thickness of furnace wall, reduce the volume of preheating furnace entirety, huyashi-chuuka (cold chinese-style noodles) outside wall temperature is reduced greatly, reach industrial furnace designing requirement, structure is more reasonable.
Described micropore thermal baffle layer 4 uses nano material to make.Nanometer micropore heat-barrier material adopts special nano grade inorganic refractory powder, there is huge specific area, contact between nano particle is minimum point cantact, the thermal resistance of point cantact is very large, make the conduction heat transfer effect of material become very little, cause the conductive heat transfer coefficient of solid special energy-saving nanometer level micropore heat-barrier material very little.
Described heat insulation brick layer 3 uses double-decker.Wherein be greater than with the inner layer heat-insulation brick density of contact raw in preheating furnace the insulating brick being wrapped in its outside.Hole in the middle of such inner layer heat-insulation brick is less, effectively can prevent the loss of raw materials for production.
The reasonability of this preheating furnace protecting wall structure is proved below with the thermodynamic metering of a specific embodiment,
Scheme one: adopt lightweight thermal insulation brick, micropore thermal insulation board and ceramic fibre material, lining gross thickness 310mm, huyashi-chuuka (cold chinese-style noodles) outside wall temperature is 73 DEG C, and detailed thermal technology checks as follows:
The program once in specific embodiment preheating furnace protecting wall structure only need 310mm can reach the heat energy parameter reached of preheating furnace needs completely, and use the thickness of other structure or material preheater stove furnace wall to need to reach 350 even more than 400 just to reach above performance, its price also can improve greatly, this protecting wall structure has high cost performance, and other overall performance is also comparatively excellent.
