Description
Technical field
The present invention relates to coal gasification blowback air technical field, especially a kind of lifting coal gasification fly-ash filter blowback air temperature methods and device thereof.
Background technology
In modern large-scale coal gasifying process, process for deashing is divided into two kinds, and a kind of is take COAL-WATER SLURRY TECHNOLOGY as the wet ash removal of representative, and a kind of is the dry method ash disposal that is representative with fine coal condensation technique.Most flying dust can be separated by dry method ash disposal before washing from synthesis gas, effectively alleviate the pressure washing ash disposal and grey water treatment portion, this makes dry method ash cleaning technology obtain application in a big way in the coal of the high ash content of process.
Powdered coal pressuring gasified technology optimum in prior art adopts HTHP fly-ash filter to carry out dry method ash disposal exactly, its filter adopts ceramic filter stick to carry out micro-filtration to the grey synthesis gas of band, this synthesis gas is from the gas in gasification furnace syngas cooler, its pressure is 3.96Mpa, temperature is 340 DEG C, dust burdening is 1.64% (wt%), and after passing through metre filter, the dust content of its synthesis gas is down to 10mg/m
3, then its fed downstream is washed the washing that system carries out synthesis gas, the preparation of synthesis gas can be completed.But, have in this process, HTHP fly-ash filter can absorb the dust that deposition is a large amount of, and then the quality of filter stick is affected; Traditional technology is adopted hot super-pressure N

2surge tank reaches 70 meters of distances to ceramic filter distance.Because the blowback of filter adopts pressure reduction control model, and blowback frequency controls by filter differential pressure, and under the low voltage difference state of filter, the flow of blowback air is very low.
And through researcher, the extent of injury that above-mentioned technology is brought is studied, and in conjunction with Liu Luwei at " Shell Coal Gasification HTHP fly-ash filter filter core Failure analysis and solution " [J]. Scientific and Technical Communication, 2013, blowback air system disclosed in 15:167-168. mono-literary composition is without heater, 150 1 170 DEG C are only had to device temperature, cause ash to make moist, not easily blow down; And after follow-up increase by three heaters, solve the problems of the technologies described above the degree of impairment analysis brought to filter after can solving the problems of the technologies described above and increase throughput and/or adding air flow blowback frequency can learn, in prior art, for in coal gasifying process, the reverse blowing disposal technology of fly-ash filter also exists following shortcoming:
One be that blowback air flow is lower, surge tank is away from filter, and then cause the purge gas holdup time in systems in which longer, GAS QUALITY changes greatly, and then cause the blowback temperature requirements that the temperature of blowback air is lower, can not meet filter, and then be difficult to the flying dust of filter surfaces to blow off, and then speed is slower to cause unlatching to be remembered, the serious weight that filter rod even can be caused to occur to corrode or filter rod bears is too large, and then when causing uncapping machine, damage filter, reduce the service life of filter.
Two is carry out emptying process to blowback air, and the flow of the purge gas in system is increased, and then when reaching the blowback effect to filter, will the energy consumption of whole system larger, and the noise when emptying process is comparatively large, causes noise pollution, is difficult to meet ecological requirements.
Three is the blowback frequencies accelerating blowback air, and then increase the flow of purge gas, increase the temperature of purge gas, the service life of pulse valve is reduced, increase cost, and then reduce the service life of filter rod, and the content of inert gas wherein can be made to increase, and then cause the difficulty of the separation process of synthesis gas and inert gas comparatively large, increase the separation costs of synthesis gas.
Four is that the entry condition temperature that will reach blowback program under e-quipment and pipe cold conditions needs to reach 200 DEG C, takes on-the-spot emptying time long, affects the driving progress of device, reduce the operating efficiency of device, increase production cost.
