Fluidized bed burned-coal boiler fly ash be raw material, heat power source be boiler exhaust gas prepare active hargil needed for device not necessarily fit
Close, and need construction fever furnace system and corresponding environment-friendly disposal system.
Summary of the invention
The technical solution used in the present invention is: a kind of using method preparing active hargil special activation tower.Its feature
It is: include activating tower assembly, point acid system, air box impulse bag-type catcher, the using method of bracket assembly.
Step one: described activation tower assembly includes tower body, high-temperature blower assembly, circulating fluidized bed combustion coal boiler fly ash spiral
Carrier, connection wind pipe component, boiler exhaust gas adapter.Described tower body upper end is designed with spiral casing feeding mouth, and lower end is designed with discharging
Mouthful.Described activation tower assembly using method is: high-temperature blower assembly is taken over from boiler heating system by boiler exhaust gas after starting
And the pipeline extraction boiler exhaust gas between dry collector, boiler exhaust gas temperature is about 160-190 DEG C, SO2Concentration is about 1000-
2500mg/m3, carry to the spiral casing feeding mouth of tower body at high-temperature blower assembly by connecting wind pipe component, recirculating fluidized bed simultaneously
The circulation connected on wind pipe component between the coal-burning boiler flying dust spiral casing feeding mouth through being arranged on high-temperature blower assembly and tower body
Fluidized bed burned-coal boiler fly ash auger conveyor delivers into connection wind pipe component and mixes with boiler exhaust gas, by regulation recycle stream
The motor speed changing bed coal-burning boiler flying dust auger conveyor can be adjusted flexibly the conveying capacity of circulating fluidized bed combustion coal boiler fly ash.
Step 2: described point of acid system includes storage tank, metering pump assembly, atomizing shower nozzle, connecting conveying pipe assembly.Described
Point acid system using method is: storage tank generally is configured with heat-insulation system, and the highest storage temperature of sulphuric acid is less than 70 DEG C, logical during use
Cross metering pump assembly and form vaporific sulfuric acid droplets through connecting conveying pipe assembly, atomizing shower nozzle.Sulphuric acid is in absorbing boiler exhaust gas
SO2Concentration improves, and is evaporated to rapidly sulfuric acid vapor simultaneously, wraps up and wash away ciculation fluidized after absorbing the waste heat of boiler exhaust gas
Bed coal-burning boiler ash surface, circulating fluidized bed combustion coal boiler fly ash granule mass transfer abundant with sulfuric acid vapor in tower body activates also
Mutually collision loses kinetic energy and enters air box impulse bag-type catcher by the discharging opening of tower body lower end under the carrying of boiler exhaust gas.
Step 3: described air box impulse bag-type catcher includes differential pressure controller, gas circuit assembly, casing.Described casing
It is made up of bag house and exhaust chamber, between bag house and exhaust chamber, is divided into the confined chamber of mutually isolation, described gas by dividing plate
Case impulse bag catcher using method is: the circulating fluidized bed combustion coal boiler fly ash after activated enters bag through casing air inlet
Filter chamber, granule falls directly into more greatly bag house bottom, and molecule is stopped by filter bay assembly and is attached to filter bay assembly surface, and tail
Gas enters exhaust chamber through filter bay assembly and enters environment treating facility process through tail gas row's mouth, is attached to the granule on filter bay assembly surface
Thing gets more and more, and bag house air pressure uprises, and when reaching design load, differential pressure controller senses and believes to actuator gas circuit assembly
Number, gas circuit component valve is opened compressed air and is purged to filter bay assembly, and the particulate matter being attached to filter bay assembly surface i.e. falls into bag filter
Bottom, room, is transported to subsequent processing by Star-like unloader.
Step 4: described activation tower assembly, point acid system, air box impulse bag-type catcher are installed in bracket assembly
On.Support frame as described above assembly using method is: bracket assembly is integrated in corresponding operation assembly in one rational space, presses
The order of technique circulation completes one by one.
Relative to prior art, the present invention is at least containing having the advantage that first, and the main material preparing active hargil uses
Circulating fluidized bed combustion coal boiler fly ash is modal pollutant and garbage during boiler for producing, loss in working space
Harm to operator is relatively big, easily causes the occupation disease such as pneumoconiosis, is the occupational of China's keypoint control.Loss
Surrounding air and soil are polluted by aerial dust simultaneously, currently mainly use the methods such as landfill to process, both
Contaminated soil, again waste resource and manpower.The present invention is then turned waste into wealth, and is used for preparing active hargil, is possible not only to subtract
Few environmental pollution, and production cost can be reduced；Second, due to circulating fluidized bed combustion coal boiler fly ash fineness reach 38 μm～
58 μm, more various prepare that the size-reduced fineness reached of hargil Ore had and too late, its specific surface area and surface in other words
Porosity is big compared with the ore deposit of mechanical lapping soil, and the degree of correctability activation is higher, and the quality of treated earth is the highest, energy-conservation while
Also preferable base material is obtained；3rd, circulating fluidized bed combustion coal boiler fly ash is gathered materials on the spot, and can directly take from bulk cement storage tank, and
Bulk cement storage tank is obturator, and not with air contact, in other words hypoxia dry environment maintains Al2O3、SiO2With uncombusted C particle
Activity, and Ore exploitation, pulverize, its water of crystallization is not destroyed in course of conveying, not forming interstitial void is difficult to be activated,
Use circulating fluidized bed combustion coal boiler fly ash can be substantially reduced the time of activation as raw material, also subtract while saving cost of transportation
The input of few process equipment, activation tower is in Sealing Arrangement, and circulating fluidized bed combustion coal boiler fly ash is difficult to effusion, is substantially reduced ring
The risk of environment pollution；4th, activation tower uses boiler exhaust gas to carry as circulating fluidized bed combustion coal boiler fly ash, mix, separate,
The medium of activation, and heat energy needed for activating process is provided and reduces the usage amount of sulphuric acid, vaporific sulfuric acid absorption boiler smoke
SO in gas2Rear concentration improves, and saves the usage amount of sulphuric acid, absorbs the waste heat in boiler smoke simultaneously and be evaporated to sulphuric acid rapidly
Steam, wraps up and washes away circulating fluidized bed combustion coal boiler fly ash surface and realize abundant mass transfer, uses activation tower to substantially increase
On the one hand the activation efficiency of hargil and reduce the activation procedure time, turns waste into wealth, high-value-use boiler exhaust gas, the most relatively
Traditional sour pool process reduces the occupation of land construction area of equipment and reduces investment；6th, the recycle stream after acid mist tail gas and activation
Change bed coal-burning boiler flying dust is directly discharged into environment treating facility process after air box impulse bag-type catcher separates (also can be by right
Sulphuric acid is reclaimed in acid mist cooling), just reduce the heavy burdens greatly for lower one rinsing process, it is meant that without taking up an area bigger rinsing
Pond, higher water consumption energy consumption, production cost is substantially reduced；7th, the pollutant that active hargil activation production process produces are such as
Exhaust emission is possible with boiler original environmental conservation treatment facility and processes, it is not necessary to again build, thus has saved construction money
Gold；8th, plant automation degree is high, and the technological process integrated intelligent of each complexity is implemented, and operates with simplicity.
