Description
Technical field
The present invention relates to a kind of is the device of raw material preparing synthetic gas with the high volatile coal, and particularly adopting with the high volatile coal is that pyrolysis system gas, gasification gas making and the pyrolysis cyclostrophic system gas of raw material is a kind of integrating device of the production synthetic gas of one.
Background technology
The existing both at home and abroad gasification type of furnace mainly is divided three classes: fixed-bed gasification furnace, fluidized-bed gasification furnace and airflow bed gasification furnace.This three classes vapourizing furnace respectively has its relative merits.
Lu Qi (Lurgi) and two sections stoves adopt the fixed bed gasification technology.Two sections stoves be a kind of be raw material with lump coal, under normal pressure, bituminous coal destructive distillation and gasification are concentrated on the device of finishing in the same vapourizing furnace that is gasified totally.It is actually on general water-gas generators (or producer) top and adds a retort section, and whole body of heater is made up of retort section and gasification section.Bituminous coal carries out low-temperature pyrolysis at this earlier, becomes fervid semicoke, and the gasification section that enters the bottom then gasifies.
Two sections stoves have generation type and two kinds of type of furnaces of water-gas type.In two sections stoves of water-gas type and since in each section of gas production the flow direction of air-flow in continuous change, pretend into the air-flow of retort section thermal barrier and other gas flow also in continuous change, so its production process is more complicated than the general fixed bed type of furnace.Working cycle generally also is made up of five stages, is the blowing stage, the steam purge stage, on blow the gas stage, following blowing gas stage and secondary steam blow off the stage.
Two sections furnacemans of two kinds of type of furnaces plant and include hydro carbons and the tar steam that low-temperature pyrolysis produces in the product coal gas, so the caloric power of gas height.But because CH
4And C
mH
nThe content height also contains in two sections producer gas of generation type＞40% nitrogen, and it is synthetic that product gas is not suitable for being directly used in alcohol ether.
Lurgi gasifier is the same with atmospheric fixed bed gasification, also is autothermal countercurrent reaction bed, and different is, and to adopt oxygen-water vapor or air-water vapor be vaporized chemical, the continuous gasification method of carrying out under the temperature condition of the pressure of 2.0～3.0MPa and 900～1100 ℃.Make coal gas through removing CO
2After calorific value about 16000kJ/m under standard state
3About.
The advantage of lurgi pressure gasification method is:
(1) can use gasification of poor coal.Ash fusion point is lower, and granularity is less, general 5～25mm, and the coal of moisture higher (20%～30%) and ash content higher (for example 30%-40%) can use, and requires lower to the physical strength and the thermostability of coal.Be specially adapted to brown coal hydrogasification, this has just enlarged the range of choice of coal for gasification greatly.
(2) pressurized gasification throughput improves.As with moisture being 20%～25% brown coal, gasification intensity can reach 2000-2500Kg/ (m
2H), this is higher about 5 times than atmospheric gasification stove, and does not increase the carry-over in the coal gas.
(3) oxygen consumption is low.The required O of gasification under 2.0MPa pressure
2Amount only is 2/3 of an atmospheric gasification, increased pressure, and the oxygen consumption can also reduce.This is main relevant with the methane formation reaction of heat release.
(4) Shandong very is reverse gasification, and coal reaches 1h at residing time in furnace, and the service temperature of Reaktionsofen and outlet of still gas temperature are low, so carbon efficiencies height (can reach 95%), gasification efficiency also can reach 80%-90%.In several gasification of poor coal technology, energy consumption is minimum.
(5) pressurized gasification only need compress the oxygen that accounts for coal gas volume 10%～15%, and this can reduce power consumption greatly concerning the user's (for example synthetic ammonia and methyl alcohol) who uses pressing gas.This recompresses 3MPa after than normal pressure gas making can save power 2/3.
(6) pressurized gasification can make the volume of vapourizing furnace, auxiliary facility and pipeline dwindle greatly, reduces the metal wastage of unit gas production rate and reduces investment.
Though the strange gasifying process advantage in Shandong is a lot, and following shortcoming is also arranged:
(1) steam decomposition rate is low.General steam/oxygen gas is than (Kg/m
3) be about 5-8, and steam resolution ratio only is 32%-38%.
(2) pressurized gasification inherent complicacy, overhaul of the equipments is frequent.
(3) tar of coal gasification course generation, oil, lipid acid, unsaturated hydrocarbons, phenol, ammonia etc. make gas purification and wastewater treatment complicated.When adopting high-volatile bituminous coal to be raw material, it is synthetic that product can not be directly used in alcohol ether.
It is the fixed bed furnace for preparing synthesis gas of raw material with coal and Sweet natural gas that Chinese patent CN2513997Y discloses a kind of, its structure is one to build body of heater that high-temperature refractory makes and the pressurized vessel that is positioned at the water jacket outside the body of heater in comprising, it is characterized in that: middle thick, last hypomere is thin, and cross section is circular; This furnace for preparing synthesis gas divides top retort section and bottom gasification section from top to bottom; The thin hypomere of epimere of described top retort section is thick, the furnace wall of the reducing transition section on it between hypomere is provided with the nozzle of 3-12 oxygen, water vapour input, the injection direction of nozzle is along the y direction up-down adjustment, and the top of thin segment is provided with and adds feed bin and lump coal charging opening; Described bottom gasification section is connected with the top retort section by the reducing transition section, and the thick hypomere of epimere is thin, is arranged with the syngas outlet pipe on the furnace wall at body of heater middle part; The furnace wall of gasification section bottom, described bottom is provided with cooling water inlet pipe and slag tap pipe, and the cooling water inlet pipe is connected with water-cooling jacket.Slag pot is connected with the slag tap pipe by the butt tube that is positioned on its wall, be provided with the clay gun device of interior dress clay gun on the slag ladle with the symmetric opposite side tank skin of butt tube, the slag ladle bottom is communicated with the strand cage, is provided with the solid slag outlet pipe, and the slag ladle top is provided with steam outlet.This invention is that raw material carries out common gasification with coal gas and Sweet natural gas.This invention breaks through conventional single material gasification, carry out the two raw materials of coal and Sweet natural gas and gasify altogether, but this technology can not reclaim valuable coal-tar chemistry product.
CNZL94106781.5 discloses a kind of ash fusing fluidized bed gasification technology.The molten poly-powdered coal fluidized bed gasification of ash is a vaporized chemical with pure oxygen and steam, under 0-6mm coal particle size and suitable gas speed, make the fine coal boiling in the bed, gas-solid two-phase thorough mixing, carry out coal gasification under the high temperature that partial combustion produces, coal is once realized the processes such as cracking of broken sticking, devolatilization, gasification, grey reunion and separation, tar and phenols in bed.The mixed characteristic of fluidized-bed reactor helps conducting heat, the use of mass transfer and powder raw material, but has also caused the carbon loss in ash discharge and the flying dust higher.Fluidized-bed process has designed special gas distributor and grey reunion tripping device according to jet current principle, forms a localized hyperthermia district in the bed, makes lime-ash reunion balling-up, reaches separating of ash group and semicoke by the difference of weight, has improved the utilization ratio of carbon.In addition, conventional fluidized-bed is for reducing the carbon content of deslagging, keep stable not slagging scorification operation, must keep bed low-carbon (LC) gray scale and low operating temperature, and ash fusing fluidized bed be the lime-ash of under non-slagging scorification situation, discharging continuously low carbon content selectively, therefore carbon content height in the bed, bed temperature is higher, do not contain tar in the product gas, it is low that washes contains the phenol amount.The Unit of Coal Gasification for Pulverized Coal with Ash method has following characteristics: (1) coal adaptability is strong; (2) gasification intensity height, the ash discharge carbon content is low; (3) product gas does not have tar, low, the easy purification of phenol content; (4) change gasification mode and can produce low, middle calorific value of gas or synthetic gas; (5) temperature of reaction is moderate, no exotic materials requirement; (6) structure of reactor is simple, and the start-stop appearance of vehicle is easy, the reliability height; (7) fine coal of ash fusing fluidized bed employing 0～6mm, this technology are not suitable for the lump coal gasification.
GSP, Shell and Texaco are typical case's representatives of pressurized air flow bed gasification technology.GSP gasifying process process mainly is by feeding system, vapourizing furnace, and the raw gas washing system is formed, and promptly is equipped with coal, gasification, three steps of slagging-off are grouped into.The solid gasified raw material is milled to behind the coal dust (～200 order), and drying is delivered to burner by concentrated phase air-flow input system. for the gasified raw material of liquid state or sludge-like then available pump deliver to burner.Gasified raw material and other vaporized chemical (oxygen, water vapour) spray into reaction chamber in the vapourizing furnace simultaneously through burner, (2.5～4.0MPa) times quick gasification reactions of generation, producing with CO and H is the hot raw gas of main component at high temperature (1400～1600 ℃), high pressure then.Mineral in the gasified raw material partly form slag.Hot raw gas and slag enter the shock chamber of bottom together by the slag-drip opening of reaction chamber bottom.Cooled raw gas removes washing system; Slag particle is solidified into glassy, discharges by the lock hopper system; The chilled water that overflows is sent Sewage treatment systems.The selection of gasification temperature is by the decision of the physicochemical property of feed coal, the technology of utilizing of determining to depend primarily on product coal gas of vapor pressure.Gasifier to start working rate height, the working rate of accessory long service life GSP vapourizing furnace are annual than higher basically, and the work-ing life of burner and water wall is also long.The start-stop car of vapourizing furnace is more flexible, and required time is shorter, produces and stablizes, and gasification efficiency and efficiency of carbon conversion are than higher.
Shell and Texaco gasifying process also mainly are by feeding system, vapourizing furnace, and the raw gas washing system is formed, and promptly is equipped with coal, gasification, three parts that remove the gred are formed.The solid gasified raw material milled for the coal grain of＜74 μ m greater than after 80%, drying is delivered to burner by concentrated phase air-flow input system.Gasified raw material and other vaporized chemicals (oxygen, water vapour) spray into reaction chamber in the vapourizing furnace simultaneously through burner, (2.5～4.0MPa) times quick gasification reactions of generation, producing with CO and H is the hot raw gas of main component at high temperature (1 400～1 600 ℃), high pressure then.Mineral in the gasified raw material partly form slag.The H of Shell technology and GSP technology
2/ C and O/C are much the same.When actual coal is tested (1500 ℃, 3.0MPa, ton coal oxygen consumption 400m
3, steam consumption 112.5kg), the H in the heating gas
2+ CO contents on dry basis is 95.42%, and the CO contents on dry basis is 4.06%, and efficiency of carbon conversion is 99.6%.
In sum, entrained flow bed gasification technology (Shell, GSP, Texaco) has technical superiority, but entrained flow gasification adopts coal dust (～200 orders, 74 μ m) be raw material, feedstock production energy consumption height takes up an area of big, investment is high, the patent royalty height, and should not be used for weak cohesiveness lump coal gasification.Lu Qi and two sections bed technology are suitable for the lump coal gasification, but pyrolysis system gas and gasification gas-making process mix and carry out, and make tar light oil content height in the product gas, and detar operation difficulty is big, the more important thing is CH in its product gas
