Description
Technical field
The block that the utility model relates to side towards the fire refractory liner puts structure, and specifically a kind of coal water slurry pressurized gasifier refractory lining is brick puts the structure forming inclination longitudinal joint.
Background technology
When coal water slurry pressurized gasifier runs, spray in burner and react in vapourizing furnace combustion chamber into the high speed water coal slurry in stove and oxygen, generate with CO and H
2for the raw gas of main component.Meanwhile, the impurity in coal and residual carbon at high temperature form liquid slag.Raw gas and slag high speed speed under the effect of pressure difference is about 50m/s by vapourizing furnace combustion chamber, then discharges out of the furnace through downtake.In vapourizing furnace, swiftly flowing material defines strong mechanical erosion to side towards the fire refractory brick in vapourizing furnace, and this mechanical erosion is the one of the main reasons causing side towards the fire refractory lining brick to damage.
The side towards the fire refractory liner of coal water slurry pressurized gasifier is made up of high-chrome brick and the high chromium chamotte mortar joint of filling between brick and brick.Compared to mechanical pressing and the high-chrome brick body that burns till of high temperature, mortar joint is the weak part of whole side towards the fire entirety.The mortar joint of side towards the fire has three kinds of existences, what namely horizontal mortar joint, longitudinal mortar joint and horizontal mortar joint and longitudinal mortar joint were formed intersect mortar joint.During gasifier operation, the side towards the fire of what swiftly flowing material was strong wash away refractory liner, first mortar joint as the overall vulnerable area of side towards the fire can expand due to mechanical erosion, accelerate the damage of refractory lining brick, especially longitudinal mortar joint, as shown in Figure 1, contact between two with the fan-shaped refractory lining brick of the circular arc in ring and form vertical longitudinal mortar joint, due to identical with Flow of Goods and Materials direction and to expand speed faster.The rapid expansion of longitudinal mortar joint and make high-chrome brick speed of damaging accelerate, accelerate the major issue that refractory lining brick replacement frequency is the domestic vapourizing furnace long-period stable operation of impact.
Utility model content
The technical problems to be solved in the utility model is: the damage speed being reduced in vapourizing furnace side towards the fire refractory liner entirety most weak part by the change of refractory lining brick shape and masonry construction, improves the work-ing life of side towards the fire refractory liner.
The utility model for solving the problems of the technologies described above adopted technical scheme is: the masonry construction of coal water slurry pressurized gasifier refractory lining brick, this masonry construction comprises the multilayer lining brick layer be arranged in parallel up and down, every layer of lining brick layer is built by laying bricks or stones by polylith refractory lining brick order and is formed a cirque structure, the cross section of described refractory lining brick is trapezoidal, and trapezoidal two waists are the hypotenuse that vergence direction is contrary, refractory lining brick quantity in every layer of lining brick layer is even numbered blocks, and adjacent two pieces of upper and lower modes of emplacements of refractory lining brick of same lining brick layer are contrary, make between adjacent two pieces of refractory lining bricks, to form longitudinal mortar joint with horizontal plane with certain inclination angle, longitudinal mortar joint of described adjacent lining brick layer is not all on same straight line.
The one side that described refractory lining brick is formed inside lining brick layer is arc-shaped structure.
The described refractory lining brick one side formed inside lining brick layer is plane or to projecting inward arc-shaped structure.
Between described neighbouring refractory lining brick formed stagger for accumulated slag and the faulting of slab ends slowing down surface water coal slurry slag flow velocity.
The beneficial effects of the utility model: the masonry construction of a kind of novel water-coal-slurry pressurized-gasification furnace refractory lining brick of the present utility model, by conversion refractory lining brick shape of cross section and the method for building mode of putting each other, traditional vertical longitudinal joint is changed into the longitudinal joint at certain inclination angle to improve the use properties of the overall weakest link of side towards the fire, extend the work-ing life of vapourizing furnace side towards the fire refractory liner, shorten the vapourizing furnace resistance to material replacement cycle, improve on-road efficiency.

Reference numeral: 1, refractory lining brick, 2, longitudinal mortar joint, 3, refractory lining brick inner face, 4, the fan-shaped refractory lining brick of circular arc, 5, vertical longitudinal mortar joint.
Embodiment
Below in conjunction with embodiment, the utility model is further detailed; The following examples are not for restriction of the present utility model, only realize mode of the present utility model as support, and any equivalent structure in technological frame disclosed in the utility model is replaced, and is protection domain of the present utility model.
As shown in Figure 2, the masonry construction of coal water slurry pressurized gasifier refractory lining brick, this masonry construction comprises the multilayer lining brick layer be arranged in parallel up and down, every layer of lining brick layer is built by laying bricks or stones by even numbered blocks refractory lining brick 1 order and is formed a cirque structure, the cross section of monolithic refractory lining brick 1 is trapezoidal, by the positive and negative placement of trapezoidal shape refractory lining brick 1 when block is put, formed and existingly acutangulate type with transverse joint, also have the longitudinal mortar joint 2 becoming obtuse angle type with transverse joint; And unlike the fan-shaped refractory lining brick 4 of circular arc of routine, form vertical longitudinal mortar joint 5.Put by the trapezoidal refractory lining brick 1 one-tenth annular of even number for every layer, the trapezoidal refractory lining brick 1 of neighbouring layer is staggered builds the longitudinal mortar joint 2 having certain inclination angle put formation and do not overlap; The refractory lining brick inner face 3 of described trapezoidal refractory lining brick 1 is smooth arc shape, linear pattern or to projecting inward arc-shaped structure.Refractory lining brick 1 one side formed outside lining brick layer is linear pattern or arc-shaped structure.
Trapezoidal shape refractory lining brick inner face 3 be linear pattern or inwardly outstanding circular arc time, form the staggered faulting of slab ends caving in and protrude, this faulting of slab ends is conducive to accumulated slag and slows down the flow velocity of refractory lining brick surface slag.
The masonry construction of a kind of coal water slurry pressurized gasifier refractory lining brick of the present utility model is when specifically using, and it is trapezoidal structure that refractory lining brick tradition being formed vertical longitudinal mortar joint changes cross section into.Every one deck lining brick layer all in the horizontal direction block-by-block is built by laying bricks or stones, build when putting and be formed with the longitudinal joint at certain inclination angle but not longitudinal joint by the positive and negative placement of trapezoidal shape refractory lining brick, every layer becomes annular to put by the trapezoidal refractory lining brick of even numbered blocks, and the trapezoidal refractory lining brick of neighbouring layer interlocks the longitudinal mortar joint built and put formation and do not overlap.By that analogy, until complete building by laying bricks or stones of all lining brick layers.
Coal water slurry good dross when this masonry way can ensure to run in stove; slag covers inside refractory lining; well protect liner not receive and wash away and violent chemical reaction corrosion; thus improve the use properties of the overall weakest link of side towards the fire; extend the work-ing life of vapourizing furnace side towards the fire refractory liner; shorten the vapourizing furnace resistance to material replacement cycle, improve on-road efficiency.
