Detailed description of the invention
Below with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail；Should be appreciated that preferred embodiment
Only for the explanation present invention rather than in order to limit the scope of the invention.
Fig. 1 is the schematic diagram of the present invention, as shown in the figure: a kind of activated coke flue gas purification system of the present invention, including absorption
Tower 4, Analytic Tower 9, for carrying the transmitting device of activated coke between adsorption tower 4 and Analytic Tower 9 and for the cigarette of fume emission
Chimney 8, described Analytic Tower 9 includes Analytic Tower preheating section 904, Analytic Tower bringing-up section 903 and Analytic Tower cooling section 901, described solution
Analysis tower preheating section 904 is provided with heater I905, and described Analytic Tower cooling section 901 is provided with chiller 902, described transmission
Device includes carrying the belt I6 of saturated active coke from adsorption tower 4 toward Analytic Tower 9 and being sent back to toward adsorption tower 4 from Analytic Tower 9 again
The belt II5 that liveliness proof is burnt, it is characterised in that: described adsorption tower 4 arrival end is disposed with flue gas booster fan 1, flue gas is mended
Water arm 2 and Smoke-heating device II3；Described Analytic Tower preheating section 904 is additionally provided with smoke induced draught fan I 10；Described parsing
Tower cooler section 901 is additionally provided with smoke induced draught fan II 7；Connected by pipeline between described each device.
Described pipeline includes between main pipeline A and adsorption tower 4 and the chimney 8 connected between booster fan 1 with adsorption tower 4
The main pipeline B of connection；Described pipeline also include booster fan 1 flue gas out enter Analytic Tower preheating section 904 branch pipe(tube) A1,
After the branch pipe(tube) A2 of main pipeline A is drawn and imported to flue gas analytically tower preheating section 904, adsorption tower 4 purifies, flue gas enters Analytic Tower
The branch pipe(tube) B2 of main pipeline B is drawn and imported to the branch pipe(tube) B1 of cooling section 901 and flue gas analytically tower cooler section 901.
Concrete, the present invention enter cigarette technological process and technological principle is:
When sintering flue-gas temperature and being 130-140 DEG C of normal range, because this temperature range is that activated coke is in adsorption tower 4
Optimal reaction temperature scope, therefore, after now booster fan 1 supercharging, not enter Analytic Tower by branch pipe(tube) A1 not pre-for flue gas out
Hot arc 904, but be all directly entered in adsorption tower 4 by main pipeline A and carry out pollutant removing reaction with activated coke.This work
Being to be realized by the valve I 11 on closedown branch pipe(tube) A1 as mode, meanwhile, moisturizing arm 2 and heater II3 do not work.
When sintering flue-gas temperature higher than 140 DEG C, intensified blower fan 1 supercharging flue gas out is divided into two-way, leads up to
Branch pipe(tube) A1 enters in Analytic Tower preheating section 904, after making this partial fume be cooled to 100 DEG C in Analytic Tower preheating section 904, so
Flue gas after drawing cooling by air-introduced machine I 10 on branch pipe(tube) A2 afterwards enters in main pipeline A and mixes with the flue gas do not lowered the temperature,
Finally, temperature is that the mixed flue gas of 130-140 DEG C enters back in adsorption tower 4 and carries out pollutant removing reaction with activated coke.This
Working method is to be realized by the valve I 11 opening on branch pipe(tube) A1, and meanwhile, moisturizing arm 2 and heater II 3 do not work.
Provide the benefit that: the temperature of flue gas in adsorption tower 4 can not only be lowered into, make reaction efficiency higher, but also can be by portion
Divide heat preheating of activated coke in resolving of flue gas, reduce the load of heater I905, the most also save water spray
Water consumption required for cooling.
When sintering, cigarette temperature is the highest, to such an extent as to when mixed flue-gas temperature remains above 140 DEG C, at this moment can be by mending
The spray cooling of water arm 2 regulates the flue-gas temperature entered in adsorption tower 4 further.Sinter cigarette temperature simultaneously and exceed absorption
In tower 4 reaction required by temperature time, the heater II 3 on adsorption tower 4 inlet flue gas pipeline does not works.And in order to overcome entrance
The flow resistance of Analytic Tower preheating section 904 part flue gas, realizes the extraction of this partial fume also by arranging air-introduced machine I 10
Imported in main pipeline A by branch pipe(tube) A2 and effectively mix.
When sintering flue-gas temperature less than 130 DEG C, intensified blower fan 1 supercharging flue gas out is the most no longer by branch pipe(tube) A1
Enter in Analytic Tower preheating section 904, but all entered in adsorption tower 4 by main pipeline A and carry out pollutant removing with activated coke
Reaction, simultaneously before low-temperature sintering flue gas enters adsorption tower 4, by regulation adsorption tower 4 inlet flue gas main pipeline A upper heater II
The workload of 3, it is achieved the flue-gas temperature entering adsorption tower 4 meets reaction requirement.This working method is by closing branch pipe(tube)
Valve I 11 on A1 realizes.
Concrete, the smoke technological process of the present invention and technological principle be:
Through purification flue gas from adsorption tower 4 out after be divided into two-way, branch pipe(tube) B1 of leading up to enter Analytic Tower cooling
In section 901, after converging intensification by the extraction of the air-introduced machine II 7 on branch pipe(tube) B2 with the flue gas on main pipeline B again after intensification, one
Rise and discharge from chimney 8.In order to overcome the flow resistance being entered Analytic Tower cooling section 901 part flue gas by branch pipe(tube) B1, logical
Cross and air-introduced machine II 7 is set to realize this partial fume and to import effective mixing of flue gas in main pipeline B by branch pipe(tube) B2.This
Working method realizes improving exhaust gas temperature by beating the valve II 7 closed on branch pipe(tube) B1.Provide the benefit that: enter the mixed of chimney
Close flue gas because of the lifting of temperature, it will advantageously reduce the risk of chimney dewing corrosion, add the service life of chimney, simultaneously
This partial fume can also be used for the preliminary cooling of activated coke in resolving, to reduce the load of chiller 902.
In the present embodiment, after activated coke is reacted with gaseous contaminant in flue gas in adsorption tower 4, reach saturated activated coke
It is delivered in Analytic Tower 9 by belt I 6, Analytic Tower 9 sends back in adsorption tower 4 by belt II 5 again after activated coke being regenerated,
Realize recycling.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, it is clear that those skilled in the art
Member can carry out various change and modification without departing from the spirit and scope of the present invention to the present invention.So, if the present invention
These amendments and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these
Change and including modification.
