Description
(1) technical field: the present invention relates to field, particularly a kind of fluidized-bed water-gas production method and device of equipped with auxiliary bed reactor with coal gasification.
(2) background technology: the technological method of existing gas maked coal is a lot, uses the producer gas generator production method of lump coal as moving-bed water-gas generators, pressurization lurgi gasifier etc.Lump coal price height, this height of system pneumatolytic, efficiency of combustion is low, and waste fuel is serious.Adopt pressure gasification process, technical difficulty is big, technology and treatment system complexity.China's utility model patent 89213611.1 is to adopt the fluidized bed pulverized coal gasification device, promptly earlier fine coal is carried out cracking in the circulating fluidized bed pyrolyzer, obtains middle calorific value of gas, and the semicoke that generates after the coal cracking is sent into the vapourizing furnace gasification again and produced low-heat value gas.This device technique is simple, and gasification intensity is big, and the gas quality of generation is good, but needs outer for steam and external heat source.Chinese invention patent 91103896.5 provides a kind of coal gas---and the integral process and the equipment of steam co-producing, calorific value of gas used for the resident in both can having produced, and can produce steam heating and generating simultaneously.This patent adopts circulating ash as coal cracked thermal source, and the concentration of the coke in the vapourizing furnace is very low, is unfavorable for gasification reaction, so gas yield is low.On the other hand, owing to only separate by separator, internal circulating load is big as the circulating ash of thermal barrier, and this causes the temperature in the pyrolyzer on the low side, and considerable fugitive constituent is remained in the semicoke, has influenced system gas productive rate.Chinese invention patent 95108875.0 has proposed a kind of new coal gas---steam co-producing scheme, and its principal character is that the bottom of boiler furnace is made up of burning bed, heat transfer bed and three fluidized-beds arranged side by side of gasifier bed.Because different wind speed about in the stove causes the particle internal recycle in the burner hearth.Falling that inner like this circulation is got off ash and be sent to fluidized-bed together through the isolating material of separator and make thermal barrier and provide heat for the gasification of gasifier bed.Though this scheme has solved the not enough problem of circulation of thermal barrier ash, can guarantee the reasonable reaction temperature in the gasifier bed, the charcoal concentration in the gasifier bed is still very low, is unfavorable for the water-gas reaction of gasifier bed.Chinese invention patent 96109833.3 has proposed a kind of coke carried heat coal gas---the device and the technology of steam co-producing.This device can effectively solve the low excessively problem of charcoal concentration in the vapourizing furnace, has guaranteed rational temperature in the vapourizing furnace.But its basic thought still adopts coke carried heat to make coal in fluidized bed cracking and gasification, if the temperature in the vapourizing furnace can not get effective control, objectionable impuritiess such as the tar in the coal gas, phenols will increase inevitably.Chinese invention patent 90105680.4 has proposed a kind of water-gas gasification process and device thereof.Its principal character is that the major portion of device is an ebullated bed vapourizing furnace and a boiling waste heat boiler.Its gas-making process is divided into air feed and two stages of gasification.At first, make the interior coal combustion temperature of burner hearth be increased to preset temperature, enter gasifying stage then, in stove, feed steam and carry out water-gas production vapourizing furnace supply air.At the band cloud of dust gas that the air feed stage comes out of the stove, enter the boiling waste heat boiler and carry out reignition, the steam of generation is used to make gas.This scheme requires low to feed coal, not only can produce coal gas but also the steam that can supply water, but it contains the very high soot particle of charcoal in a large number and can not fully be used to make gas with what gas was taken out of in the stove, and vaporization rate is low, and the charcoal transformation efficiency is not high, boiling waste heat boiler complicated operation.
(3) summary of the invention: the objective of the invention is to overcome above-mentioned weak point of the prior art, and a kind of water-gas production method and device that can make not the equipped with auxiliary bed reactor that the coal tar fly ash granule that transforms fully makes full use of is provided.The inventive system comprises fluidized-bed gasification furnace 1, cyclonic separator 3 and auxiliary bed reactor 4 and waste heat boiler 15 and subsidiary conduit.The present invention is divided into the gasification of fine coal and two parts of gasification of the burnt flying dust of fine coal that do not transform fully in whole coal gasification course.Fine coal mainly carries out the intermittent gasification reaction in fluidized-bed gasification furnace 1, the flue gas of generation, coal gas discharging or collection after cyclonic separator 3 enters waste heat boiler 15 coolings.Isolate by cyclonic separator 3 with going out the high temperature coal tar flying dust that does not transform fully that kiln gas, coal gas take out of, enter auxiliary bed reactor 4 and carry out gasification reaction.Gasification process in auxiliary bed reactor 4 is the supply air, makes the burnt burning of the fine coal additional heat in the auxiliary bed reactor 4, improves temperature, feeds steam again and carries out gasification reaction.In auxiliary bed reactor 4, supply air, steam simultaneously, then produce mixed gas, supply air, steam respectively, produce flue gas during then for air, produce coal gas during for steam.Coal gas that auxiliary bed reactor 4 produces or flue gas and most of reacted soot particle enter fluidized-bed gasification furnace 1, further circulation.Auxiliary bed reactor 4 these outer fluidized-beds of joining burn, gasify the burnt particle of the fine coal that does not transform fully that comes out from cyclonic separator 3, make the operation ceiling temperature of auxiliary bed reactor 4 interior temperature and fluidized-bed gasification furnace 1 keep close, enter the ash particle of fluidized-bed gasification furnace 1 like this from auxiliary bed reactor 4, when fluidized-bed gasification furnace 1 in the blowing stage, just can be from heat absorption in the fluidized-bed gasification furnace 1, on the contrary, can blow-time be shortened the material particles in the heat transferred fluidized-bed gasification furnace 1 of himself.When fluidized-bed gasification furnace 1 in the system gas stage, the ash particle that enters fluidized-bed gasification furnace 1 from auxiliary bed reactor 4 can make system gas time lengthening because its temperature is high and remain broadly stable.The major ingredient that produces when auxiliary bed reactor 4 air vapors enter simultaneously is H
