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, a kind of be representative with COAL-WATER SLURRY TECHNOLOGY wet ash removal, a kind of be representative with fine coal condensation technique dry method ash disposal. Overwhelming majority flying dust can be separated by dry method ash disposal before washing from synthesis gas, effectively alleviating the pressure washing ash disposal and ash water treatment portion, this makes dry method ash cleaning technology obtain large range of application in processing the coal of high ash content.
Powdered coal pressuring gasified technology optimum in prior art adopts High Temperature High Pressure fly-ash filter to carry out dry method ash disposal exactly, its filter adopts pottery filter stick that band ash synthesis gas is carried out microfiltration, 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 being filtered by filter, the dust content of its synthesis gas is down to 10mg/m3, then its fed downstream is washed system carry out the washing of synthesis gas, the preparation of synthesis gas can be completed. But, have in this process, High Temperature High Pressure fly-ash filter can absorb the substantial amounts of dust of deposition, and then the quality of filter stick is affected; Traditional technology is adopted hot supertension N2/CO2Filter apparatus is carried out reverse blowing disposal as blowback air by (8.05Mpa, 225 DEG C), particularly uses N during driving2, subsequent production unit produces CO2Rear use CO2Carry out reverse blowing disposal.
And the source flow process of purge gas of the prior art, be namely exactly nitrogen or carbon dioxide produce after quality improve flow process and be: supertension N2/CO2From compressibility, the N of a part of supertension2/CO2(8.1Mpa, 120 DEG C) is through supertension N2/CO2Heat exchanger heats to (8.05Mpa, 225 DEG C), through overheated supertension N2/CO2Surge tank, one goes gasification furnace cross/Quench mouth blowback; Another stock enters ceramic filter blowback endless tube, is interrupted purging pottery filter stick by blowback pulse valve, and blowback endless tube is provided with to lead and drenches emptying on the spot. Another part enters supertension N2/CO2Surge tank, is down to 5.2Mpa by pressure-regulating valve and is divided into two strands, and one passes through high pressure N2/CO2It is sent to hot N after heat exchanger heating2/CO2User; Another stock removes cold N2/CO2User.
Further, in prior art, for the ease of flying dust subsequent treatment and conveying, high temp/pressure filter is arranged on 86 meters of platforms of device, and the supertension N of blowback air2/CO2Heater and hot supertension N2/CO2Surge tank arranges 16 meters of platforms of device. Blowback air goes out N2/CO2Surge tank reaches 70 meters of distances to ceramic filter distance. Owing to the blowback of filter adopts pressure reduction control model, and blowback frequency is controlled by filter differential pressure, and under the low voltage difference state of filter, the flow of blowback air is very low.
And the extent of injury above-mentioned technology brought through research worker is studied, and in conjunction with Liu Luwei at " Shell Coal Gasification's High Temperature High Pressure fly-ash filter filter element Failure analysis and solution " [J]. Scientific and Technical Communication, 2013,15:167-168. blowback air system disclosed in a literary composition is without heater, 150-170 DEG C is only had to device temperature, cause ash to make moist, not easily blow down; And after three heaters of follow-up increase, can solve the problem that above-mentioned technical problem and increase throughput and/or strengthen and solve the degree of impairment analysis that above-mentioned technical problem brings to filter after air-flow blowback frequency and be appreciated that, 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 relatively low, surge tank from filter farther out, and then cause that the purge gas holdup time in systems is longer, GAS QUALITY changes greatly, and then cause the blowback temperature requirements that the temperature of blowback air is relatively low, can not meet filter, and then be difficult to blow off the flying dust of filter surfaces, and then speed is slower to cause unlatching to be remembered, the serious filter rod that results even in occurs the weight that corrosion or filter rod bear too big, and then when causing unlatching machine, damage filter, reduce the service life of filter.
Two is that blowback air is carried out emptying process so that the flow of the purge gas in system increases, and then when reaching the blowback effect to filter, will the energy consumption of whole system bigger, and the noise when emptying processes is relatively big, causes noise pollution, it is difficult to meet ecological requirements.
The three blowback frequencies being to speed up blowback air, and then increase the flow of purge gas, increase the temperature of purge gas, the service life making pulse valve reduces, increase cost, and then reduce the service life that filter is excellent, and also the content of noble gas therein can be made to increase, and then cause that synthesis gas is relatively big with the difficulty of the separation process of noble gas, increase the separation costs of synthesis gas.
Four is that the entry condition temperature reaching blowback program under equipment and pipeline cold conditions needs to reach 200 DEG C, takes on-the-spot emptying time long, affects the driving progress of device, reduce the work efficiency of device, increase production cost.
