Description
Technical field
The present invention relates to coal chemical industry pulp water processing technology field, a kind of gasification furnace dreg removing system and deslagging side are specifically provided
Method.
Background technique
Air flow bed pressurized gasification technology is compared to traditional gasification technology such as fixed bed in equipment volume, gas producing efficiency, environmental protection
Etc. have big advantage, it has also become the development trend of Modern Coal-based Chemical.Either coal water slurry pressurized gasifier is still done
Coal dust pressurized-gasification furnace, since the reaction in gasification furnace is to carry out in a high voltage state, coal after the reaction was completed remaining clinker without
Method is expelled directly out gasification furnace, and clinker passes through the dreg-locking hopper discharge of gasification furnace bottom, and dreg-locking hopper periphery valve is according to scheduled
Sequence switch realizes the operation such as dreg-locking hopper collection slag, pressure release, flushing, deslagging, pressurising, ensure that being smoothly discharged for filter residue.
But it builds bridge at the top of generally existing slag breaker in tapping process in the prior art, valve between gasification furnace and dreg-locking hopper
The problems such as interior leakage can not be effectively isolated, and dreg-locking hopper blowdown line blocks.Wherein, dreg-locking hopper wash tub pipe linearly coupled problem is especially prominent
Out, at the major hidden danger for influencing safety in production.It is found through field observation, dreg-locking hopper wash tub pipe linearly coupled, which occurs mainly in, to be let out
Before pressure end deslagging and at the end of deslagging.Pressure release terminates the reason of flushing water pipeline vibration before deslagging when being dreg-locking hopper pressure release, molten
The gas of solution in water carries a part of water secretly and flows out dreg-locking hopper, makes to form hole at the top of dreg-locking hopper；Wash tub pipe at the end of deslagging
When the reason of linearly coupled is deslagging, flushing water pipeline and deslagging pipeline have difference in flow, and the flushing dose into dreg-locking hopper is made to be less than row
The water of dreg-locking hopper out causes dreg-locking hopper top at the end of deslagging to form hole.Due to the presence of dreg-locking hopper upper cavity, rinse
Flushing water in water pipeline flows rapidly into dreg-locking hopper, is full of in a flash to dreg-locking hopper hole, water velocity rapid drawdown, forms water hammer
Phenomenon causes pipeline vibration of washing by water, brings great hidden danger to safety in production.Major part company is using increase spring branch now
Frame increases expansion joint, changes the modes such as pipeline trend, although the case where alleviating pipeline vibration to a certain extent, still
Pipeline vibration cannot be inherently eliminated.
Summary of the invention
