Description
Technical field
the present invention relates in coal water slurry or coal dust gasification furnace of pressurized aerated bed chilling device, particularly a kind of new type of airflow bed gasification furnace chilling ring being applied to water Quench pattern.
Background technology
The gasification technology of coal is a kind of by the clean coal technology of coal high-efficiency clean utilization, the key equipment of coal water slurry or coal dust pressurized air flow bed gasification technology is vapourizing furnace, gasification is there is anti-in coal dust or the coal water slurry vaporizer in vapourizing furnace, the generation high-temperature crude synthesis gas of about 1200 ~ 1700 DEG C and the slag of molten state enter shock chamber, realize high-temperature crude synthesis gas and be separated with the gentle slag of the cooling of slag in shock chamber.The key part of shock chamber is chilling ring; the effect of chilling ring is evenly distributed on downtake inwall by Quench liquid; form moisture film; for the slag of high-temperature synthesis gas and molten state carries out Quench; and protect downtake not burnt out by high-temperature synthesis gas and slag, directly have influence on the normal operation cycle of vapourizing furnace in shock chamber the work-ing life of chilling ring and downtake.
Existing chilling ring structure comprises outer lip ring, epipharynx ring, the import of Quench liquid, the outlet of Quench liquid, downtake, forms Quench liquid distribution chamber, form Quench liquid and export annular space between the epipharynx ring of annular and downtake between the outer lip ring of annular and epipharynx ring.Quench liquid declines along downtake internal surface after entering through Quench liquid distribution chamber by the import of Quench liquid, realizes the humidifying cooling to high-temperature synthesis gas and slag.But also there is the problems such as complex structure, work-ing life is shorter in existing chilling ring of gasifying furnace, is mainly manifested in:
(1) chilling ring of gasifying furnace of the prior art due to its side towards the fire directly and high-temperature synthesis gas and slag contacts, cause chilling ring epipharynx ring working temperature too high, long-term hot operation greatly reduces the work-ing life of chilling ring, and high-temperature synthesis gas and slag also can reduce the work-ing life of chilling ring to the direct souring of chilling ring simultaneously.
(2) because chilling ring water-in contains thin ash particle, directly wash away epipharynx ring, cause chilling ring to wash away perforation, study of water film distribution is uneven, causes downtake distortion, bulge, dross seriously, even burns, cause gasification system to be forced to stop production.
(3) chilling ring outer lip ring and epipharynx ring are solid forging, manufacture and tooling cost higher, and due to the restriction of internal diversion block, cannot realize globality during processing assembling, needs cut open into some sections, then carry out assembly welding, affect assembly precision.
Summary of the invention
The present invention is directed to defect and the deficiency of chilling ring of the prior art existence, a kind of novel fluidized bed chilling ring of gasifying furnace is provided, when overcoming the work of existing chilling ring directly and high-temperature synthesis gas and slag contacts and its temperature of causing too high, connect the defect of washing away and making its service life reduction, make chilling ring side towards the fire resistance to deformation, wear-resistant, erosion resistibility improve greatly.Overcome downtake because study of water film distribution is uneven, cutout and the distortion caused, the defect of burning, also overcome the defect of chilling ring of the prior art difficulty when manufacturing assembling simultaneously.
