Abstract
The utility model provides a kind of large-scale fluidized roaster external thermal insulation structure, the external thermal insulation structure successively includes refractory brick, insulating brick, steel plate, heat-preservation cotton and aluminium sheet from the roaster furnace from the inside to the outside, the refractory temperature of the refractory brick is greater than 1500 DEG C, the steel plate be carbon steel, the aluminium sheet with a thickness of 1 ~ 10mm.Large size fluidized roaster external thermal insulation structure provided by the utility model, the heat-preservation cotton are close to setting on the outside of the steel plate, and the aluminium sheet on the outside of the heat-preservation cotton mainly plays the protection heat-preservation cotton.The steel plate uses carbon steel material, and design temperature not only ensure that the intensity of the roaster furnace shell is unaffected between 250 ~ 300 DEG C, but also casing temperature is made to be higher than SO3Dew-point temperature, not only avoid the low-temperature corrosion of furnace shell, extend the service life of furnace shell, and this external thermal insulation mode, make the temperature of outermost layer aluminium sheet close to environment temperature, far below traditional inside holding mode, so that roaster radiation loss greatly reduces, utilization rate of waste heat is improved.
Description
Technical field
The utility model relates to chemical metallurgy technical field more particularly to a kind of large-scale fluidized roaster external thermal insulation knots
Structure.
Background technique
In metallurgical and chemical industry, existing fluidized roaster furnace insulation setting be by the way of inside holding, it is this
Not only radiation loss is big for set-up mode, and easily causes shell corrosion, reduces the service life of furnace body.Therefore, it needs to grind
Study carefully and develops a kind of fluidized roaster external thermal insulation structure.
Summary of the invention
In order to solve the above technical problems, the utility model provides a kind of large-scale fluidized roaster external thermal insulation structure, institute
External thermal insulation structure is stated from the roaster from the inside to the outside successively including refractory brick, insulating brick, steel plate, heat-preservation cotton and aluminium sheet.
Wherein, the refractory temperature of the refractory brick is greater than 1500 DEG C.
Wherein, the steel plate is carbon steel.
Wherein, the aluminium sheet with a thickness of 1 ~ 10mm.
Preferably, the aluminium sheet with a thickness of 3 ~ 7mm.
It is further preferred that the aluminium sheet with a thickness of 4mm, 5mm, 6mm.
The utility model has the beneficial effects that
Large size fluidized roaster external thermal insulation structure provided by the utility model, from the roaster furnace from the inside to the outside according to
Secondary includes refractory brick, insulating brick, steel plate, heat-preservation cotton and aluminium sheet.The heat-preservation cotton is close to setting, the heat preservation on the outside of the steel plate
Aluminium sheet on the outside of cotton mainly plays the protection heat-preservation cotton.The steel plate uses carbon steel material, and design temperature is 250 ~ 300
It between DEG C, not only ensure that the intensity of the roaster furnace shell was unaffected, but also casing temperature made to be higher than SO3Dew-point temperature, no
The low-temperature corrosion for only avoiding furnace shell extends the service life of furnace shell, and this external thermal insulation mode, makes outermost layer aluminium sheet
Temperature improves waste heat so that roaster radiation loss greatly reduces close to environment temperature, far below traditional inside holding mode
Utilization rate.
Detailed description of the invention
It, below will be to needing attached drawing to be used in embodiment in order to illustrate more clearly of the technical solution of the utility model
It is briefly described, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the utility model, corresponds to this
