Description
Technical field
The utility model belongs to Coal Gasification Technology field, is mainly used for the cleaning dust of dust-laden crude synthesis gas, and in particular to
A kind of cleaning dust device of synthesis gas.
Background technique
China is the country of a rich coal, oil-poor, few gas, can be generated using raw coal gasification and is with carbon monoxide and hydrogen
Main synthesis gas produces methanol, can also synthesize the chemicals such as ammonia, ethylene glycol, is that China is the most universal at this stage, directly and will
The production line adhered to for a long time.Often dust burdening is bigger for the crude synthesis gas generated after gasifying, if cannot effectively divide
Defection causes adverse effect to downstream section.
The molten ash that the high-temperature synthesis gas that gasification reaction generates in gasification furnace vaporizer carries, through chilled water and water-bath
Cooling solidify slag separates, but certain solid granule is also had in synthesis gas, and main component is lime-ash and carbon residue.It is right
Fine ash content height, granularity are small in the entrained flow gasification especially dried coal powder technique using the higher raw coal of ash content, synthesis gas, if
It cannot be separated well, after synthesis gas takes down-stream system to, easily cause pipeline, the dust stratification of bed, blocking and catalyst
Poisoning, the final stable operation for influencing device.
Existing a part of ash disposal, dedusting technology reduce fine ash only in gasification furnace external expansion, not in shock chamber and take
Band, and the use of external washing facility, not only long flow path, number of devices are more, are unfavorable for maintenance, whole to remove dirt fruit
Difference；And drag losses are big, constrain efficient, the stable operation of gasification installation.For example, patent document CN105062574A is disclosed
A kind of efficient combined type dust-laden synthesis gas washing dust-extraction unit, although it is contemplated that partial particulate is passed through rotation outside shock chamber
Wind separator is separated, and improves the water quality that wash tower bottoms are used as chilled water, but in the indoor primary wash effect of Quench
Difference, the equipment being related to is more, long flow path, and equipment room is attached using high temperature, high-pressure gas pipelines, needs to consider pipe stress,
Pipe arrangement difficulty is big, equipment and pipeline investment are high.
Patent document CN106398779A discloses a kind of synthesis gas washing dedusting dewatering system, is only in original venturi
On washer plus scrubbing tower process, cannot meet the technological requirements, dustiness is higher, influences the case where downstream section production, simply
Increase subsequent processing device, extend process and remove remaining fine ash.Although this method also can be realized its purpose, simultaneously
The reason of former flow and method dedusting effect difference is not sought from principle, water quality is more preferable though Venturi scrubber has used, it is solid to contain
Lower high temperature, high pressure buck (low pressure buck is pressurized, is pumped into Venturi scrubber after heating) are measured, but chilled water still uses
The high buck of wash tower bottoms dust burdening affects the indoor primary wash ash disposal of Quench, keeps synthesis gas band ash serious, to washing
The ash disposal efficiency requirements of tower and tube bank separator are higher；The structure of tube bank whizzer is unfavorable for cleaning, and is easy fouling blockage,
System resistance drop can also be increase accordingly.Meanwhile the process flow is there is also similar long flow path, stress pipe arrangement difficulty is big,
Equipment pipe invests high disadvantage.
Patent document CN107189824A discloses a kind of efficient ash handling equipment of polynary gasification furnace exit gas and technique, choosing
Selected the lower condensate liquid of solid content through flashing after washing system discharge it is pressurized after as washing water.Though this method is one
Determine to improve detersive efficiency in degree, but whole washing waters especially larger chilled water of dosage is all from low pressure condensate liquid and adds through pump
Pressure, so that the energy consumption that system pumps at runtime is very big；Though having used the better condensate liquid of water quality, shock chamber in shock chamber
It is inside not provided with dedusting, the foam removal facility of auxiliary, so that synthesis gas band ash, band water are serious, multistage Venturi scrubbing can only be passed through
The form that device matches increases weight a large amount of fine ash wetting in synthesis gas in order to separate, in this way but also the resistance of system will rise
It is high；It is to run counter to theoretical research by the way of spray washing for micro little particle fine ash washing together last in synthesis gas
, inferior separating effect is washed, equipment needs are very huge just to be met the requirements.The patent overall flow is too long, equipment is more and
And it is big, stress pipe arrangement is more complex, equipment and pipeline investment are big；Energy consumption height, resistance are big when device is run, comprehensive operation efficiency
It is low, belong to " disregarding cost " formula and improves dust removing effects.
In a kind of synthesis gas washing treatment process disclosed in patent document CN107189824A, washing flow there is no
Significant change still adds the process of scrubbing tower using Venturi scrubber, and after passing through accurate filter filtering high temperature, high pressure Heisui River
Direct reuse does as chilled water and washing water the mode for improving dust removing effects；But the grain graininess in Heisui River is small, it is accurate
Filter is easy blocking, it has not been convenient to clean, can't realize long period, stable industrialized production operation at present.
