Abstract
The utility model discloses a novel gasifier arch apex structure, wherein a fire-resistant material liner is arranged on the inner wall of the arch apex of a casing of a gasifier. The fire-resistant material liner comprises a chromium-aluminum-zirconium brick layer, a chromium-corundum brick layer, a heavy pouring material layer and a fiber-resistant fiber compressible material layer from inside to outside, wherein the chromium-aluminum-zirconium brick layer and the chromium-corundum brick layer are bricked in a seam staggering manner. According to the novel gasifier arch apex structure, a fire-resistant material structure of a weak part at the lower part of the original arch apex is thickened, so that the service life of the whole fire-resistant liner structure of the arch apex is prolonged effectively; and the chromium-aluminum-zirconium brick layer and the chromium-corundum brick layer are bricked in a seam staggering manner, so that the local overtemperature phenomenon caused by air moving in the straight seams of the arch apex structure is avoided effectively.
Description
Technical field
The utility model belongs to the coal water slurry pressurized gasifier technical field, relates in particular to and a kind ofly can effectively prevent the vault overtemperature, can improve the Novel gasification furnace vault construction in vault life-span.
Background technology
Coal water slurry pressurized gasifier is the key equipment of coal liquefaction, and it is take coal as raw material, and after high-temperature vapor, oxygen mix, series of chemical occurs, and the solid coal is converted into contains CO, H
2, CH
4Deng gas, for the synthesis of industrial chemicals and town gas such as ammonia, its liner refractory materials used also will suffer the erosion of reducing atmosphere, acid slag and washing away of high temperature gas flow except bearing High Temperature High Pressure.
Domestic currently used a kind of four nozzle opposed type vapourizing furnaces, this arch roof of gasification furnace structure as shown in Figure 1, described vault has refractory liner, described refractory liner comprises chromium aluminium zirconia block layer, the heavy cast bed of material and the compressible bed of material of refractory fibre from inside to outside, because the burner of four nozzle opposed type vapourizing furnaces is positioned at the body of heater middle part, the furnace high-temperature air-flow can produce the vault refractory materials and wash away.In the gasifier operation process, the vault bottom of this structure is stood long-term washing away, corrode and is easily formed weak part, thereby causes overtemperature.And the side towards the fire refractory materials in this structure be etched consume more than half after, straight-through seam easily occurs and collaborate.
Summary of the invention
In order to address the above problem, the utility model aims to provide a kind of Novel gasification furnace vault construction, and there is not weak part in this vault construction bottom, reduces the phenomenon odds of collaborating, and effectively extends vault refractory materials work-ing life.
In order to realize appealing goal of the invention, the utility model adopts following technical scheme:
A kind of Novel gasification furnace vault construction, be provided with refractory liner on the vault inwall of vapourizing furnace furnace shell, refractory liner comprises chromium aluminium zirconia block layer, chrome corundum brick layer, the heavy cast bed of material and the compressible bed of material of refractory fibre from inside to outside, and chromium aluminium zirconia block layer and chrome corundum brick the layer fissure of displacement are each other built by laying bricks or stones.
Owing to adopting technique scheme, the utlity model has following superiority:
(1) with the structure of refractory thickening of former vault bottom weak part, effectively extend the whole refractory liner structure of vault work-ing life;
(2) chrome corundum brick layer and chromium aluminium zirconia block layer adopt fissure of displacement masonry construction, can prevent effectively that vault construction from the straight-through local overheating phenomenon of collaborating and causing of stitching occurring and occuring.
Description of drawings
Fig. 1 is traditional arch roof of gasification furnace structural representation;
Fig. 2 is vault construction schematic diagram of the present utility model;
In figure: the compressible bed of material of 1-refractory fibre; The 2-heavy cast bed of material; 3-chromium aluminium zirconia block layer; The 4-furnace shell; 5-chrome corundum brick layer.
Embodiment
Below in conjunction with drawings and Examples, the utility model is done further and explained.
As shown in Figure 2, a kind of Novel gasification furnace vault construction, be provided with refractory liner on the vault inwall of vapourizing furnace furnace shell 4, refractory liner comprises chromium aluminium zirconia block layer 3, chrome corundum brick layer 5, the heavy cast bed of material 2 and the compressible bed of material 1 of refractory fibre from inside to outside, chromium aluminium zirconia block layer 3 and chrome corundum brick layer 5 fissure of displacement are each other built by laying bricks or stones, can prevent effectively that vault construction from the straight-through local overheating phenomenon of collaborating and causing of stitching occurring and occuring.
Arch roof of gasification furnace structure of the present utility model is the improvement of carrying out on the basis of traditional gasification furnace structure, development is: the refractory liner structure of the cylinder inboard wall of the traditional vapourizing furnace of maintenance is constant, and the refractory liner of cylinder inboard wall is made of chromium aluminium zirconia block layer; Set up the chrome corundum brick layer between the refractory-lined chromium aluminium of vault zirconia block layer and the heavy cast bed of material, and guarantee that the internal diameter of vault chromium aluminium zirconia block layer is consistent with the internal diameter of the chromium aluminium zirconia block layer of shell portion.Be provided with the transition supporting section between the refractory liner of vault and cylindrical shell, be used for the chromium aluminium zirconia block layer that the supporting arch top is divided.
At first this vault construction should paste the compressible bed of material 1 of refractory fibre at the furnace shell inwall in building process.Then build chromium aluminium zirconia block layer 3 by laying bricks or stones, then be close to chromium aluminium zirconia block layer and build chrome corundum brick layer 5 by laying bricks or stones, guarantee when the chrome corundum brick layer is built by laying bricks or stones that vertical mortar joint and chromium aluminium zirconia block layer 3 stagger, do not allow to occur straight-through seam.At last, in chrome corundum brick layer rear cast chromium corundum mould material, and then build successively other each layers by laying bricks or stones, until that whole vault is built by laying bricks or stones is complete.
Claims (1)
1. Novel gasification furnace vault construction, be provided with refractory liner on the vault inwall of vapourizing furnace furnace shell (4), it is characterized in that: refractory liner comprises chromium aluminium zirconia block layer (3), chrome corundum brick layer (5), the heavy cast bed of material (2) and the compressible bed of material of refractory fibre (1) from inside to outside, and chromium aluminium zirconia block layer and chrome corundum brick the layer fissure of displacement are each other built by laying bricks or stones.
