Abstract
The utility model mainly relates to an arch roof structure of a gasification furnace, in particular to a refractory lining structure of the arch roof of the gasification furnace. The arch roof of the gasification furnace comprises a steel casing of the arch roof of the gasification furnace, and a mouth of the furnace; a refractory insulating layer of the arch roof of the gasification furnace comprises a facing pavior layer. A back lining layer comprises a lightweight highstrength mullite insulating layer.The utility model is characterized in that a ceramic fiber blanket layer is arranged between the highpurity corundum brick facing pavior layer and the mullite insulating layer; a ceramic fiber blanket insulating layer is arranged between the mullite insulating layer and the inner wall of the steel casing of the arch roof. The refractory lining structure of the arch roof of the gasification furnace.of the utility model has obvious refractory insulating effect. After the material is changed from the heavy feed stock such as the residual oil into the lightweight material such as the natural gas,the temperature of the outer wall of the metal of the arch roof of the gasification furnace is reduced by 8-12 C; therefore, the normal operation of the gasification furnace is ensured.
Description
Technical field:
The utility model relates generally to the gasification furnace vault construction, relates in particular to the structure of gasification furnace vault refractory liner.
Background technology:
6.0MPa residual oil and natural gas gasifying stove are the technologies that English lotus shell global company (Shell Globe SolutionInternational) developed and dropped into industrialized a kind of non-catalytic partial oxidation method preparing synthetic gas, being widely used in residual oil, light oil, natural gas is that raw material generates in the device of synthetic ammonia.The raw material lighting is a raw material when adopting natural gas or refinery exhaust, moves on the high temperature hot-zone in the gasification furnace and flame shortens, and does not almost have the black area and causes that gasification furnace vault heat flow density strengthens, and the vault radiation is strengthened and the gasification furnace vault outer wall overtemperature that causes.Its fire door is because temperature overheating, and unreasonable structure, and easy scaling loss have a strong impact on the normal cycle safety and stability operation of gasification furnace.
From the update search result, domestic to solving gasification furnace vault overtemperature problem, mainly concentrate on residual oil gasifier and the coal slurry gasifier, pertinent literature has " coal slurry gasifier vault overtemperature exploration of reasons and precautionary measures (Coal Chemical Industry .2001; (2)-55-57) ", " improvement of Texaco's residual oil gasifier refractory liner (chemical fertilizer industry .2000; 27 (5) .-45-47) ", " prolong residual oil gasifier refractory liner life-span countermeasure (Xinjiang chemical industry .1992; (2) .-46-51) ", " gasification furnace furnace shell overtemperature and transformation (Chemical Engineering Design .2001,011 (004) .-43-44) ".
On engineering, prior art is in order to reduce the gasification furnace dome temperature, taked the method that adds water-cooling jacket or furnace roof refractory heat-insulating lining is thickeied 360mm at vault, and the vault insulated lining of thickening is generally 3 layers.
Prior art comes with some shortcomings: the firstth, add water-cooling jacket at the gasification furnace vault, and not only need the weld zone is heat-treated, and the cooling water pressure temperature controlling is very crucial.Because the dew-point temperature of gasification furnace is about 186 ℃, cooling water must be higher than this temperature.Like this, for the investment for trnasforming urban land height of gasification furnace, and increased a jacket water pressure and temp control system.The secondth, set up cooling water jecket, make heat loss increase the also corresponding increase of consumption of raw materials.
To 360mm, in order to keep the stability of vault, straight tube place tangent line moves down, and vault weight is increased, and investment increases for thickening vault refractory heat-insulating lining.
Summary of the invention:
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of gasification furnace vault is provided.Structure setting by optimizing vault refractory liner, refractory insulating layer and optimize backing layer high-strength light mullite insulating layer structure solves because raw material changes gasification furnace vault overtemperature problem behind the natural gas into by residual oil.Another purpose is that gasification furnace vault and fire door and gasification burner tip are complementary.
The purpose of this utility model can be by realizing by the following technical solutions: a kind of gasification furnace vault includes gasification furnace vault steel body case (9), and fire door (6), gasification furnace vault refractory insulating layer include sees fiery face brick layer (1); Back sheet includes high-strength light mullite thermal insulation layer (3), and its main feature is that the high-purity corundum brick is seen and is provided with the fine blanket layer (2) of making pottery between fiery face brick layer (1) and the mullite thermal insulation layer (3); Be provided with the fine blanket heat insulation layer (4) of making pottery between mullite thermal insulation layer (3) and vault steel body case (9) inwall.
Described gasification furnace vault also includes between vault steel body case (9) and the heat insulation layer (4) and is provided with nano heat insulating layer (7).Nanoscale heat insulating material is guaranteed to obtain lower vault outside wall temperature, and the effect that the operating flexibility of gasifier temperature is increased is more obvious.
The groove (18) that fire door extension brick (5) is provided with is embedded on the boss (11) of its back sheet brick (10) setting.The change acquisition of fire door structure and the reasonable coupling of gasification burner tip so that form best flow field and temperature field in gasification furnace, guarantee that the available gas composition is greater than 95.5%.
The described high-purity corundum brick (12) of seeing fiery face brick layer (1) is being met with it on each adjacent face of fire, is provided with groove (13) and projection (14) one to one; Join with mortise and tenon between two high-purity corundum bricks (12).
The mullite brick (15) that described mullite thermal insulation layer (3) is adopted interlaces for integral body, is respectively equipped with recessed (16), convex surface (17) on its corresponding, between two mullite bricks (13) with the concave, convex misconnection.The concavo-convex misconnection structure of high-strength light mullite brick is avoided because the gasification furnace vault metal outer wall temperature control that brickwork joint is collaborated and caused.
The utility model gross thickness is controlled at 300-340mm, make residual oil change natural gas after the vault outside wall temperature be limited in 300 ℃.
The beneficial effects of the utility model are:
Adopt gasification furnace vault refractory heat-insulating of the present utility model to have remarkable result.At first be raw material is changed into lightweight materials such as natural gas by heavy charges such as residual oil after, move on the high temperature hot-zone in the gasification furnace and flame shortens, almost do not have the black area and cause that gasification furnace vault heat flow density strengthens, the vault radiation is strengthened, gasification furnace vault metal outer wall temperature does not only raise, descend 8～12 ℃ on the contrary, guaranteed the normal running of gasification furnace.Next is that the reasonable Arrangement of vault and fire door structure makes it to have obtained best flow field and temperature field coupling and reached best gasification result with the natural gas gasifying burner.Therefore, the utility model both had been applicable in the gasification furnace transformation or newly-built gasified boiler system after the raw material lighting, also can be used for raw material between heavy charge and lightweight material switching or mix with arbitrary proportion in the gasified boiler system of burning, thereby can shorten greatly and transform the duration, reduce investment outlay.Satisfy the long period of gasification installation, oepration at full load requirement, the economic benefit of raising device.
