Description
Technical field
The utility model belongs to coal water slurry pressurized gasifier cylinder refractory brick technical field, and in particular to a kind of water-coal-slurry
Pressurized gasification furnace tube refractory brick.
Background technique
Coal water slurry pressurized gasifier feeds intake when running, and water-coal-slurry and oxygen are spurted into furnace by burner, and reaction generates CO
With the raw gas such as H2.Water-coal-slurry generates cinder through pyroreaction, along furnace wall downwards through in down-comer discharge furnace.The process along with
Swiftly flowing coal gas and cinder washing away strongly to cylinder working lining, this is also the important of influence cylinder working lining service life
One of reason.
Coal water slurry pressurized gasifier cylinder working lining is refractory brick+refractory wass masonry construction, the fire resisting of different circular layers
Horizontal mortar joint is formed between brick, forms vertical mortar joint between circular layer refractory brick.Vertical mortar joint compared with horizontal mortar joint, vertical mortar joint because
It is consistent with the traffic direction of gasification furnace reaction mass, become the main object washed away.Working lining refractory brick selects anti-cinder to invade
The good high chromium matter refractory brick of corrosion, forms on 1000t large-tonnage pressure dual-side brick machine, through 1600 DEG C or more high temperature firings
At flexural strength is up to 30MPa or more.The adhesive bending strength of refractory wass about 10MPa.To sum up, in gasifier operation process
In, it is washed away by swiftly flowing air-flow and the strong of cinder, vertical mortar joint is washed away fall off first, and gap is reserved, and causes fire resisting
The erosion rate of brick is accelerated, the service life reduction of monolithic lining.
In the prior art, building between cylinder refractory brick and it is (as shown in Figure 1) to be formed by vertical mortar joint is that front and back is through,
It will form the continuous action that high speed cinder washes away mortar joint, eventually lead to whole mortar joint material and be washed totally, it is resistance to influence cylinder
The structural stability of firebrick and the service life of working lining；Inventor is based on defect in the prior art and has developed a kind of water-coal-slurry
Pressurized gasification furnace tube refractory brick, can well solve problems of the prior art.
Utility model content
In order to solve the above-mentioned technical problem the utility model, provides a kind of coal water slurry pressurized gasifier cylinder refractory brick,
Its structure designs service life that is simple, scientific and reasonable, extending coal water slurry pressurized gasifier cylinder refractory brick；Pass through change
The left and right end face plane shape of traditional refractory brick is changed to concave, convex face respectively, makes it by the left and right end surface shape of cylinder refractory brick
After the completion of masonry, the vertical mortar joint structure that front and back penetrates through between adjacent refractory brick becomes nonlinear arcuate structure, front mortar joint mud
After slurry is washed, because rear portion has the refractory brick of protrusion to block, the damage rate of vertical mortar joint will be effectively reduced；The utility model energy
It enough solves to build between cylinder refractory brick to be formed by vertical mortar joint, since continuous erosion of the high speed cinder to vertical mortar joint is made
With, cause refractory brick service life reduce the problem of.
The technical scheme adopted by the utility model is a kind of coal water slurry pressurized gasifier cylinder refractory brick, including it is resistance to
Firebrick ontology, left side, right side；The elongate body of refractory brick ontology arc shape, refractory brick ontology include left side, and left side is solid
The left position of arc intermediate is set calmly, and left side is the crowning of arc, and right side is fixed at arc intermediate
Right end position, right side be recessed arcwall face, between left side and right side be arc intermediate；In refractory brick ontology
The crowning of left side docks masonry with the recessed right side in another piece of refractory brick ontology, docks and builds between refractory brick ontology
The refractory brick to form annular is built, the building mortar layer between refractory brick ontology is arc mortar joint.
The left end of the arc intermediate is fixedly connected with compacting with raised left side and forms one, the right end of arc intermediate
It is fixedly connected with compacting with recessed right side and forms one.
The leading flank of the arc intermediate is the arc being backwardly recessed, and the trailing flank of arc intermediate is recessed forward
Arc.
The use process of this coal water slurry pressurized gasifier cylinder refractory brick are as follows: first will be in single refractory brick ontology
The crowning of left side is docked with the recessed right side in another piece of refractory brick ontology, while along coal water slurry pressurized gasifier
The permanent internal layer of cylinder, which docks, to be built, and is docked with several refractory brick ontologies and is built the refractory brick for forming annular；When by high velocity stream
When dynamic air-flow and cinder passes through the arc mortar joint between refractory brick ontology, since the mortar joint between refractory brick ontology is arc,
Swiftly flowing air-flow and cinder will be mitigated to wash away refractory brick mortar joint, to extend the service life of refractory brick；With
Upper process is exactly the use process of this coal water slurry pressurized gasifier cylinder refractory brick.
The elongate body of the refractory brick ontology arc shape, refractory brick ontology include left side, and left side is fixed at arc
The left position of shape intermediate, left side are the crowning of arc, and right side is fixed at the right end position of arc intermediate,
Right side is recessed arcwall face, is arc intermediate between left side and right side；Wherein by the left side of refractory brick ontology
It is arranged to the arc of protrusion, the right side of refractory brick ontology is arranged to recessed arc；Primarily to improving refractory brick ontology
Between docking tightness, while make refractory brick ontology formed arc mortar joint, to improve the block between refractory brick ontology
Intensity is built, the service life of annular tile is extended, improves the resistance swiftly flowing air-flow and cinder of annular tile
It washes away.
The crowning of left side in the refractory brick ontology and the recessed right side pair in another piece of refractory brick ontology
Masonry is connect, docking builds the refractory brick for forming annular between refractory brick ontology, and the building mortar layer between refractory brick ontology is arc
Mortar joint；The main purpose being arranged in this way is to form the refractory brick of annular, primarily serve protection coal water slurry pressurized gasifier cylinder
The effect of body.
Building mortar layer between the refractory brick ontology is arc mortar joint；The main purpose being arranged in this way is to pass through arc
The design of shape mortar joint, it is therefore prevented that cinder washes away the direct of adhesive in mortar joint, improves the intensity of refractory brick ontology.
The utility model has the beneficial effects that the technical program provides a kind of coal water slurry pressurized gasifier cylinder refractory brick,
Its structure designs service life that is simple, scientific and reasonable, extending coal water slurry pressurized gasifier cylinder refractory brick；This is practical new
Type, which is able to solve to build between cylinder refractory brick, is formed by vertical mortar joint, since high speed cinder is to the continuous erosion of vertical mortar joint
The problem of acting on, refractory brick service life caused to reduce；The service life for substantially increasing refractory brick, improves between refractory brick
Structural stability.
