Inventor has found, since the temperature in use of calcination activation rotary furnace calcination activation is 900~1280 DEG C, and recycle stream Change the temperature of bed coal-fired furnace cavity as 900 ± 50 DEG C, because more than after above-mentioned temperature, fluosolids, that is, coking loses fluidized state causes It is unable to operate normally, while burner hearth no longer arranges heating surface, calcination activation returns in addition to fluidisation layer segment arrangement water wall surface The solution of operating temperature needed for converter is inside conveying fine coal powder burning to supplement required calorific value.
Inventor has found that the effect of material returning device is the high-temperature solid particle that cyclone separator is separated, and is led to through standpipe The isobaric air compartment air-supply of bottom is crossed, burner hearth is sent back to by refeed line and is burnt again, there is U-shaped valve, U-shaped valve between standpipe and refeed line Bottom has isobaric air compartment air-supply to ensure that high-temperature solid particle fluidizes.The pressure difference of stock column and gun pressure is driving in standpipe in standpipe The guarantee that high-temperature solid particle is successively conveyed to burner hearth.Since this case is recirculating fluidized bed roasting revolution all-in-one oven, roast The discharge end for activating rotary furnace is air classifier, and design requirement flue gas flow rate is relatively low, to reduce the finished particle kinetic energy carried, so as to Sub-elect the finished particle of enough fineness, and to burner hearth air-supply need to overcome burner hearth, cyclone separator, injector, spiral blade, The resistance of the components such as air classifier, therefore the air-supply requirement to circulating fluidized bed combustion coal burner hearth is that wind pressure is big, air quantity is small, therefore burner hearth Pressure head it is larger, by the requirement of the pressure balance of stock column and gun pressure in above-mentioned standpipe, then the design of the stock column requirement for height of standpipe It is higher, i.e., the returning charge amount of high-temperature solid particle is just high, and returning charge amount is fired with entering the recirculating fluidized bed of calcination activation rotary furnace The ratio of coal burning boiler flying dust determines that in other words, returning charge amount increases, circulating fluidized bed combustion coal boiler fly ash via cyclone separator Increase, the load increase of air classifier, the efficiency of separation reduce.To solve the above problems, the port of export in refeed line designs guiding Room, guiding room are negative pressure state, and by designing the guide wire by refeed line outlet, reduction refeed line exports the gun pressure of part, So as to reduce the stock column height of standpipe, realize material balance and ensure the purpose of separative efficiency, make circulating fluidized bed combustion coal stove with Calcination activation rotary furnace effectively can be combined and be run well.
Inventor has found that fire coal divides after 900 ± 50 DEG C of temperature of recirculating fluidized bed burner hearth are burnt, then through cyclone separator From coarse granule returns to burner hearth through material returning device and burns away, 38 μm of the fine grained grain size carried in the flue gas of cyclone separator discharge ~58 μm, main component Al2O3、SiO2With uncombusted C, referred to as circulating fluidized bed combustion coal boiler fly ash, with good work The main component SiO of property2Content is about 45~55%, Al2O3Content is about 35~38%, and uncombusted C content is about 3~5%, as Impurity component Si forms SiO after circulating fluidized bed combustion coal boiler furnace high temperature is burnt under the relatively low situation of oxygen amount in coal2Gas Colloidal sol, with Al2O3It carried under one's arms with uncombusted C particles by high velocity smoke, hit broken, separating at high temperature and enter calcination activation rotary furnace, had There are larger specific surface area and cation exchange capacity, in other words, circulating fluidized bed combustion coal boiler fly ash fineness is compared with kaolinite Through the fineness that mechanical crushing reaches had and it is too late, activity function is more preferable, and impurity is less.
Inventor find, to realize that the high-value-use of circulating fluidized bed combustion coal boiler fly ash prepares kaolin, need according to 《Kaolin and its test method》GB/T 14563-2008 reach its chemical composition and physical property requirements, although every profession and trade pair The specific requirement of kaolin clay filler is not quite identical, but wherein fineness and Al2O3/SiO2Than having more specific regulation, therefore profit Do not stop rolling, phase mutual friction when being turned round in calcination activation rotary furnace with it with high aluminium ball, realize and returned to resting on calcination activation The grinding of converter bottom cycle fluidized bed burned-coal boiler fly ash, and under 900~1280 DEG C of high temperature of calcination activation, Al2O3、 SiO2Since intermolecular bonding energy declines, spacing increases while completing lattice reconstruct, it is easy to get under high aluminium ball rubbing Fineness reaches 1000~1200 mesh kaolin finished products, while the component particles that the mutual rubbing of high aluminium ball comes off also add to height In the soil finished product of ridge, impurity to be separated is not needed.
Inventor has found, to prevent exhaust emission from leaking, and calcination activation rotary furnace both ends need the sealing of reliable design, by In furnace body internal-external temperature difference is larger and fineness of materials is up to more than 1000 mesh, and working condition is barotropic state, the sealings such as labyrinth, filler Form is easy to fail, and only mechanical seal is relatively suitble to, and being typically employed in dynamic and static ring sealing face spray hydraulic oil just can be very well The purpose of solving cooling, lubricating, is dust-proof.
Inventor has found that the purpose for designing distributor is the powders such as supplement high aluminium ball and conveying directed agents, cleaned coal, is gone out at it Design spreader main purpose in mouth end is the above-mentioned material of dispersion and is uniformly mixed with circulating fluidized bed combustion coal boiler fly ash, uniformly mixed Powder after conjunction is swept along by high-temperature flue gas jumps on spiral blade, by centrifugal force effect along spiral blade rolling tangential direction get rid of to Calcination activation rotary furnace inner wall is lost kinetic energy by the effects that inboard wall of furnace body friction, high aluminium ball stack layers, gravity, spiral blade obstruction Bottom of furnace body is rested on, by the mutual rubbing of high aluminium ball, obtains and is swept along feeding air classifier by flue gas after enough fineness.
Inventor has found that air classifier inlet design is three along the circumferential direction uniformly distributed spiral imports, can avoid roasting The distinguished and admirable road short circuit of activation rotary furnace both ends cigarette and guide that spiral blade raises advance along calcination activation rotating cylinder spiral inner wall Whirlwind wind band, and since import draught area relatively exports big, flue gas flow rate reduces under conditions of equal ventilation quantity, also means The particle kinetic energy of carrying reduces, so as to sub-elect the finished particle of enough fineness.
Relative to the prior art, the present invention, which at least contains, to be had the advantage that：First, circulating fluidized bed combustion coal boiler fly ash is pot Most common waste in stove production process, it is larger to the injury of personnel in workplace, the occupational diseases such as pneumoconiosis are be easy to cause, The aerial dust of loss pollutes the environment, main at present to be handled using the methods of landfill, not only contaminated soil, but also Waste of resource and manpower.And the present invention is then turned waste into wealth, and is used to prepare kaolin, can not only be reduced environmental pollution, and And production cost can be reduced；Second, it to realize that the high-value-use of circulating fluidized bed combustion coal boiler fly ash prepares kaolin, need According to《Kaolin and its test method》GB/T 14563-2008 reach its chemical composition and physical property requirements, although each row Industry is not quite identical to the specific requirement of kaolin clay filler, but wherein fineness and Al2O3/SiO2Than there is more specific regulation, because Do not stop rolling, phase mutual friction when this is turned round using high aluminium ball in calcination activation rotary furnace with it, realize and live to resting on roasting Change the grinding of rotary furnace bottom cycle fluidized bed burned-coal boiler fly ash, and under 900~1280 DEG C of high temperature of calcination activation, Al2O3、SiO2Since intermolecular bonding energy declines, spacing increases while completing lattice reconstruct, under high aluminium ball rubbing easily It obtains fineness and reaches 1000~1200 mesh kaolin finished products, while the component particles that the mutual rubbing of high aluminium ball comes off also are supplemented Into kaolin finished product, impurity to be separated is not needed；Third, the sealing of calcination activation rotary furnace both ends is using mechanical seal side Case can be reliably completed under hot conditions and seal problem, avoid the discharge of exhaust emission；4th, air classifier inlet design is Three along the circumferential direction uniformly distributed spiral imports can avoid the distinguished and admirable road short circuit of calcination activation rotary furnace both ends cigarette and guide spiral The whirlwind wind band to advance along calcination activation rotating cylinder spiral inner wall that blade raises, and since import draught area relatively exports Greatly, flue gas flow rate reduces under conditions of equal ventilation quantity, also means the particle kinetic energy of carrying and reduces, enough thin so as to sub-elect The finished particle of degree；5th, by designing the guide wire by refeed line outlet, reduction refeed line exports the gun pressure of part, from And reduce the stock column height of standpipe, realize material balance and ensure the purpose of separative efficiency, make circulating fluidized bed combustion coal stove and roasting Burning activation rotary furnace effectively can combine and run well.
