Abstract
The utility model is related to a kind of coal water slurry gasification furnace structure, the in particular to a kind of gasification furnace of unsymmetric structure thermocouple brick.The cross-sectional shape of a kind of gasification furnace thermocouple brick of the unsymmetric structure proposed, the thermocouple brick is sector；Have to place the short slot of thermocouple on the upper surface or lower face of the thermocouple brick；It is characterized in that：The center line of the short slot and the center line eccentric setting of thermocouple brick；The bottom surface of the short slot is the arc surface coordinated with thermocouple.The utility model avoids erosion of the high temperature slag stream to thermocouple brick both sides, extends the service life of thermocouple brick, improves the operational efficiency of gasification furnace.
Description
Technical field
The utility model is related to a kind of coal water slurry gasification furnace structure, in particular to a kind of gasification furnace of unsymmetric structure
With thermocouple brick.
Background technology
Texaco Water-coal-mud Gasification Technology and four nozzle coal water slurry gasification technologies are added by feeding manner of water-coal-slurry
It calms the anger fluidized bed gasification process.Texaco gasifier and four nozzle gasification furnaces are the critical equipments for realizing gasification process；Gasification furnace is grasped
During work, in order to monitor the reaction temperature in stove, thermocouple is frequently provided with to measure；Thermocouple passes through thermocouple brick
It is inserted into stove；The composite structure of thermocouple brick and thermocouple brick on stove is as shown in Figure 1, Figure 2, Figure 3 shows.
In use, the combination position of thermocouple brick, stack shell brick is all originated, is formed at this gasification furnace in the position
Longer straight joint, straight joint are the weak links of gasification furnace furnace lining structure, and the thermal stress that gasification furnace is generated in heating and cooling all can be
This carries out concentration release, can lead to the extension of the cracking of straight joint；Since there are a large amount of molten state slag liquids, slag also can in gasification furnace
Under the drive of high-speed flow, straight joint is washed away, the cracking due to straight joint and expansion, erosion can also aggravate；Two kinds of damages
Mode is mutually promoted, and the service life of thermocouple brick is shortened；Reduce the operational efficiency of gasification furnace.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose a kind of gasification furnace thermoelectricity of unsymmetric structure
Even brick.
The utility model is to complete above-mentioned purpose to adopt the following technical scheme that：
The cross-sectional shape of a kind of gasification furnace of unsymmetric structure thermocouple brick, the thermocouple brick is sector；It is described
Have to place the short slot of thermocouple on the upper surface or lower face of thermocouple brick；The center line of the short slot and thermocouple brick
Center line eccentric setting；The bottom surface of the short slot is the arc surface coordinated with thermocouple.
The utility model proposes a kind of unsymmetric structure gasification furnace thermocouple brick, thermocouple brick is symmetrical
Structure is changed to the asymmetrical structure in left and right；Thermocouple be combined up and down build by laying bricks or stones when, can in each formation in the left and right of thermocouple hole
One step；When the presence of step can connect to avoid thermocouple brick with stack shell brick, a straight joint is formed；Avoid high temperature slag
The erosion to thermocouple brick both sides is flowed, the service life of thermocouple brick is extended, improves the operational efficiency of gasification furnace.
Description of the drawings
Fig. 1 is the structural schematic diagram of thermocouple brick in the prior art.
Fig. 2 is Fig. 1 vertical views.
Fig. 3 is the usage state diagram of thermocouple brick in the prior art.
Fig. 4 is the structural schematic diagram of the utility model.
Fig. 5 is the vertical view of Fig. 4.
Fig. 6 is the usage state diagram of the utility model.
In figure；1, thermocouple brick, 2, short slot.
Specific implementation mode
The utility model is illustrated with reference to the drawings and specific embodiments：
As shown in figure 4, a kind of gasification furnace of unsymmetric structure thermocouple brick, the cross-sectional shape of the thermocouple brick 1
For sector；Have to place the short slot 2 of thermocouple on the upper surface or lower face of the thermocouple brick；In the short slot 2
The center line eccentric setting of heart line and thermocouple brick 1；The bottom surface of the short slot 2 is the arc surface coordinated with thermocouple.
Before laying bricks, lower layer's thermocouple brick is first set, carries out building by laying bricks or stones for both sides stack shell brick；Upper layer thermocouple brick is carried out again
It builds by laying bricks or stones, then carries out building by laying bricks or stones for both sides stack shell brick.
Claims (1)
