Description
Technical field
The utility model relates to Coal Chemical Industry coal water slurry pressurized gasifier cinder notch technical field of structures, is a kind of protection type coal water slurry pressurized gasifier cinder notch structure specifically.
Background technology
No matter be Texaco's formula top spray coal water slurry pressurized gasifier, still have the Multiinjector contraposition-type coal-water slurry pressurized gasifier of independent intellectual property right, the refractory liner of its inside all presents the phenomenon of different sites obvious difference in work-ing life.Especially the side towards the fire refractory materials at cinder notch position, its life-span is that whole side towards the fire refractory liner is the shortest.Therefore, the work-ing life of significantly improving cinder notch position side towards the fire refractory materials can effectively reduce blowing out frequency of maintenance and servicing time, reduces social resources waste, brings huge economic benefit to enterprise and society.
The high temperature available gas produced in vapourizing furnace combustion chamber and liquid lime-ash all can flow through cinder notch and discharge, because cinder notch temperature relative combustion room upper temp is lower, the liquid slag that coal water slurry reaction is formed can become the larger lime-ash of the viscosity of solid-liquid because temperature reduces, the effect of cinder notch ensures that the thick gas of the rear generation of coal water slurry reaction and lime-ash are discharged from coal water slurry pressurized gasifier combustion chamber smoothly, its guarantee reaches deslagging, the mechanism of scavenging action is that the funnel-shaped structure that cinder notch top and cone end chamfered portion are formed makes circulation area sharply reduce at cinder notch position, pressure increase, air-flow velocity sharply increases, simultaneously due to cinder notch bottom ring widening of the ring, space increases, pressure reduces, lime-ash disintegrates and is dispersed into small-particle and enters downtake with air-flow.In existing cinder notch structure, the upper and lower ring refractory brick in cinder notch bottom forms faulting of slab ends structure, and the edge of every ring refractory brick is right-angle structure, is therefore more easily damaged by airflow scouring; The right-angle structure of the every ring in cinder notch bottom easily makes air-flow form eddy current and cinder notch refractory brick is come off, and then damages vapourizing furnace brick plate and chilling ring, causes vapourizing furnace to stop in emergency, may lead to security incident time serious.
Therefore fully ensure the stability of cinder notch portion structure and available protecting is formed to bottom brick plate and chilling ring, being conducive to the safety coefficient improving gasifier operation, reducing the probability occurring accident.No matter develop a kind of life-span is longer, safety coefficient is higher coal water slurry pressurized gasifier cinder notch side towards the fire structure of refractory distributing style to coal chemical industry enterprises, or to entire society, all there is huge meaning.
Summary of the invention
The technical problems to be solved in the utility model is: existing coal water slurry pressurized gasifier cinder notch refractory brick is easily damaged, and brick plate in use easily deformation occurs, and cinder notch structural stability is poor, and then causes cinder notch safety coefficient low, and work-ing life is short.
The utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of protection type coal water slurry pressurized gasifier cinder notch structure, this cinder notch structure comprises gasification furnace wall and is arranged on the slag notch be made up of many rings refractory brick inside gasification furnace wall, this slag notch is made up of the upper cinder notch connected up and down and lower cinder notch, the top of described upper cinder notch is in the funnel-form connected with Failure of Gasifier Conical Bottom inclined-plane, its underpart is straight-tube shape, described lower cinder notch is in the straight-tube shape mutually concordant with upper cinder notch bottom, and supported by the brick plate be arranged on below gasification furnace wall bottom it, inside edge bottom described lower cinder notch protrudes from the edge of brick plate.
The side that described lower cinder notch protrudes from brick plate edge is provided with the protecting sheet for preventing brick plate temperature distortion to downward-extension, is also provided with the deformation space for preventing from extruding during protecting sheet expanded by heating brick plate between this protecting sheet and brick plate.
Described protecting sheet and the undermost refractory brick of lower cinder notch are structure as a whole, and section is L-type.
Described protecting sheet is back taper inclined-plane near the side of cinder notch medullary ray.
The beneficial effects of the utility model:
The utility model, by the vibrational power flow of lower cinder notch and upper cinder notch bottom same inner diameter, avoids traditional slag notch faulting of slab ends type structure and easily causes downdraft to form eddy current in cinder notch bottom, the generation of damage slag notch refractory brick phenomenon; Effectively increase the net thickness that cinder notch refractory brick weathers, lower floor's refractory brick can also be formed upper strata refractory brick and lift completely simultaneously, increases the stability of structure; The setting of slag notch hypomere protecting sheet can solve the problem of the yielding damage of cinder notch brick plate.Structure is overall while maintenance cinder notch quick change construction, extends the work-ing life of cinder notch refractory brick and brick plate, adds the safety and stability of gasifier operation.
