Description
One, technical field
The present invention relates to coal chemical technology, especially, relate to the coal gas fluidized bed gasification.
Two, background technology
Gasification is the cleaning and efficient tap and the gordian technique of utilizing of coal.Entrained flow gasification is the New type coal cocurrent flow type gasification technology that grows up nearest decades, vaporized chemical and coal dust or coal slurry enter vaporizer through nozzle, the pyrolysis of coal, burning and gasification reaction almost carry out simultaneously, high temperature has guaranteed being gasified totally of coal, and the mineral substance in the coal leaves vapourizing furnace after becoming slag.Compare with traditional gasification technology, the pressurized entrained-bed gasification temperature is high, processing power is large, gas effective constituent is high, gasification efficiency is high, is future coal gasification technology developing direction.
It is different with layout that air-flow bed coal-gasification technique is pressed nozzle quantity at present, can be divided into the outspoken spray of single spraying and multi-nozzle to spraying two classes.All adopt the outspoken spray mode of single spraying such as Texaco coal water slurry gasification and GSP coal gasification, its advantage is structure and control is simple, cost is low, but because the pressurized gasification process relates to fluid flow and associated transmittance process and complicated chemical reaction process under high temperature, high pressure, the heterogeneous conditions, the outspoken atomization effect of single spraying is undesirable, and gasification efficiency is relatively low; The treatment capacity amplitude of accommodation is little in addition, capacity is little, can't satisfy the demand of maximization.Shell and multi-nozzle coal water slurry process have adopted multi-nozzle to the spray structure, improved vapourizing furnace mass-and heat-transfer effect, the index such as efficiency of carbon conversion, energy consumption increases, but, Shell multi-nozzle structure has increased the complicacy of equipment, particularly need independently linkage control system, thereby increased equipment manufacturing cost, operation easier and maintenance rate; The opposed gasifying process of coal water slurry multi-nozzle is because the distribution of flame field easily causes the ablation of furnace roof section refractory materials, and the furnace roof refractory brick life only has some months, has greatly improved investment.
Vapourizing furnace raw gas out has very high temperature (1200～1700 ℃), in order to allow the melting ashes of carrying secretly solidify, simultaneously in order to reclaim heat energy, need to cool off it.At present, the hot mode that moves of industrial employing has two kinds: a kind of is up pot destroying process, produces high pressure steam; Another kind is descending water chilling process, produces the saturation water raw gas.Up pot destroying process thermo-efficiency is high, and caloric power of gas is high, is fit to follow-up IGCC generating; But up pot destroying process only is the part heat that has reclaimed gas, the heat of slag is not reclaimed, and adopt the cooled coal gas Quench to add useless pot and reclaim that the mode equipment of preheating is complicated, the cooled coal gas energy consumption is high.The chilling process gasification furnace structure is simple, and moisture-laden gas is favourable for the subsequent conversion operation, is suitable as very much the Chemical Manufacture synthetic gas, but the energy recovery of water chilling process is difficult, and effectively gas (CO+H2) content is lower, and caloric power of gas is low; Chilling process Heisui River amount is large in addition, and the biochemical treatment difficulty is high.Although descending pot destroying process once awards recovery to the heat that reclaims synthetic gas and slag, because sticking grey fouling blocking channel, seldom industrial applications.
Patent CN101724470A mentions a kind of novel water-coal-slurry gasification furnace and utilizes top spray to chew and the side nozzle of the upper spray of tilting, and is formed centrally Y type impingement region in burner hearth, has strengthened caloic transmission and mixing process, has accelerated speed of reaction and has improved efficiency of carbon conversion; Because the effect of top spray mouth, the coal water slurry residence time of Y type impingement region prolongs, flame direction is downward, can not impact furnace roof section refractory materials up to 2000 ℃ flames; Refractory masses is under the cooling of water (vapour) cold wall pipe in addition; the inwall wall temperature is lower than the temperature of solidification of melt cinder; knot one deck solidifies slag blanket on the flame retardant coating surface; play the effect with slag anti-slag, protection flame retardant coating; greatly prolonged the work-ing life of vapourizing furnace, but the liquid deslagging, energy fails to reclaim; the Heisui River amount is large, and the biochemical treatment difficulty is high.Therefore develop large capacity, high-level efficiency, highly regulate, high calorie reclaims, low investment, macrocyclic large-scale airflow bed gasification furnace are present Coal Chemical Industry one of the difficult problem that needs to be resolved hurrily.
