Activated carbon desulfurization has desulfurization degree height, denitration can be achieved at the same time, de- dioxin, dedusting, do not generate waste water and dregs
The advantages that, it is extremely promising flue gas purifying method.Active carbon can regenerate at high temperature, when temperature is higher than 350 DEG C, absorption
(sulfur dioxide is solved for the pollutants such as oxysulfide, nitrogen oxides, dioxin on the activated carbon generation fast resolving or decomposition
Analysis, nitrogen oxides and dioxin are decomposed).And as the temperature rises, the reproduction speed of active carbon is further speeded up, regeneration
Time shortens, and preferably regenerating active carbon temperature is approximately equal to 430 DEG C in general control Analytic Tower, therefore, ideal parsing temperature
Spending (or regeneration temperature) is for example in 390-450 DEG C of range, more preferably in 400-440 DEG C of range.
For sintering flue gas exhaust temperature between 110-170 DEG C, SO is contained in the inside2, NOx, dust, dioxin, heavy metal etc.
Multiple pollutant, and active carbon flue gases purification is suitable for sintering flue gas temperature discharge section, it can be achieved that multi-pollutant just
High-efficient purification is cooperateed with, multiple pollutant can be deviate from simultaneously on a set of equipment, realizes by-product SO2Resource utilization, and

The active carbon of dirt stops non-fouling active carbon flowing, and active carbon mobility continues to be deteriorated, be adsorbed on dirty body, and dirty body continues to grow
Greatly, until the blanking hole of blocking heat exchanger, causes Analytic Tower fouling blockage and corrosion.
In addition to this, the active carbon in active carbon Analytic Tower is grain structure, and " bridging " is easy to appear in changeover portion
Situation, if there is active carbon " bridging ", as shown in figure 8, leading to the active carbon stream below " bridging " in Analytic Tower cooling section
Dynamic pipeline is sky, before the discharge gate discharge below the active carbon in the pipeline analytically tower, and is certainly existed at blow-off valve
The situation of leaking out of air, the enough oxygen content into the air in Analytic Tower, air along hole active carbon flow duct
Into changeover portion, at 400 DEG C or more the spontaneous combustion of active carbon easily occurs for the active carbon temperature in changeover portion, damage Analytic Tower and
Active carbon in Analytic Tower.In addition, if there is the case where " bridging ", due to the flowing of active carbon in bringing-up section or changeover portion,
The active carbon of " bridging " is easy " Tower Bridge ", and 400 DEG C or more of active carbon is caused directly to fall near Analytic Tower bottom discharging mouth
Active carbon on, parsing tower bottom leaks into oxygen content in the air in Analytic Tower from discharge gate due to the presence of discharge gate, 400
DEG C or more active carbon fall down, easily cause active carbon Analytic Tower discharge gate neighbouring position burn, and burn activity
Charcoal is fed directly to the equipment such as adsorption tower from discharge gate discharge, and the oxygen content adsorbed in tower is more sufficient, suction of easily igniting
Active carbon in attached tower, consequence are hardly imaginable.

Through inspection information it is found that carbon steel heat transfer coefficient 48.85W/ (m DEG C), air conduction coefficient 0.0317W/ (m
DEG C), since the thermal coefficient of air is low, parsing active carbon that can effectively to cooling section upper end (or in First Transition section)
It is isolated with the heat transfer of the cooling air in heat exchange cooling section.
Century-old in flue gas adsorption treatment technical operation, active carbon Analytic Tower is used for the Dissociative adsorption active carbon of pollutant,
Enter the active carbon in active carbon Analytic Tower by high-temperature heating (indirect heating), so that the pollutant parsing adsorbed in active carbon
With separate, then the gas containing pollutant is delivered to the techniques such as the acid making system in downstream recycled and handled.Through
Active carbon after crossing active carbon Analytic Tower bringing-up section, eliminates the pollutant wherein adsorbed, cools down after cooling section, so
After be recycled to the devices such as adsorption tower recycling.But active carbon is heated to 400 DEG C or so in bringing-up section, subsequently into
Cooling section, the interior input of cooling section is that normal temperature air is cooled down.In general, cooling section upper section (close to the position of changeover portion) by
In the presence of cooling gas, temperature is generally 100-150 DEG C or so, even lower than 100 DEG C, and the top of cooling section is transition
Section, changeover portion is interior containing a large amount of parsing gas, and the ingredient for parsing gas is mainly vapor, SO2、SO3、NH3, dust etc., mistake
The top for crossing section is bringing-up section, and temperature is 400 DEG C or more, parses gas in changeover portion, sharply due to the temperature in cooling section

One changeover portion (being equivalent to changeover portion in the prior art) and heat exchange cooling section (being equivalent to cooling section in the prior art) separate
It comes, the active carbon avoided in First Transition section is directly connect with the interior air in heat exchange cooling section by upper perforated plate (steel plate)
Touching.It is normally passed through cooling gas in heat exchange cooling section, active carbon is cooled down.
In the present invention, bringing-up section, transition cooling section and heat exchange cooling section are shell structure, and recuperated gas walks shell side,
Active carbon walks tube side, and active carbon and recuperated gas pass through indirect heat exchange.Wherein, in bringing-up section, heated gas heats bringing-up section
Interior active carbon parses the pollutant adsorbed in active carbon so that active carbon temperature in the section increases.In heat exchange cooling section
Then interior, in cooling gas cooling heat transferring cooling section active carbon passes through Analytic Tower so that active carbon temperature in the section reduces
Discharge gate discharge, is recycled to the equipment such as adsorption tower and continues to use.First Transition section and the second changeover portion are holostrome activated carbon structure.
Wherein: First Transition section is for being discharged the pollutant parsed from active carbon, and the gas containing pollutant is from First Transition section
SRG gas vent discharge on side wall.Second changeover portion is used for buffers active charcoal, avoids entering cooling section due to First Transition section
There is the case where " bridging " in position (upper tube Board position)；Due to the presence of the second changeover portion, even if First Transition section enters cooling
There is the case where " bridgings " in fragment position (upper tube Board position), the presence of the second changeover portion and the cooling section still active charcoal that exchanges heat,
Play the role of material envelope, avoids air from blow-off valve and leak into Analytic Tower, directly contacted with high temperature active charcoal.
In transition cooling section, closed space can be.By the way that one section of transition cooling section is arranged, due to air conduction system
Number is far smaller than carbon steel heat transfer coefficient, and there are the transition cooling sections of one section of air exclusion for First Transition section and heat exchange cooling section centre
With the second changeover portion, play good heat insulation, avoid active carbon in First Transition section with heat exchange cooling section in temperature
Greatest differences lead to quick refrigeration.Due to the presence of transition cooling section and the second changeover portion, active carbon is in First Transition section
Temperature be 400 DEG C or so, by the buffering of transition cooling section and the second changeover portion, enter back into heat exchange cooling section and cooling air
Body heat exchange cooling, transition cooling section and the second changeover portion are located between changeover portion and heat exchange cooling section, play the work of temperature buffer
With, avoid the sharply temperature drop of active carbon, so as to avoid parsing gas condensation situations generation, effectively prevent fouling.It protects
Proper flow of the active carbon in Analytic Tower has been demonstrate,proved, while having avoided corrosion of the fouling to Analytic Tower.
Preferably, gas can be passed through in transition cooling section, the temperature being further ensured that in transition cooling section, more added with
Effect plays the role of transition and heat preservation.For example, the temperature in changeover portion is 400 DEG C or so, the temperature to exchange heat in cooling section is
150 DEG C hereinafter, be passed through gas in transition cooling section, guarantee that the temperature in transition cooling section is 150-400 DEG C, thus well
Transitional function is played, so that active carbon realizes that ladder cools down in Analytic Tower, avoids the sharply decline of temperature.
Preferably, it is delivered to gas in transition cooling section, the gas after can be hot wind stove heating, certainly due to Analytic Tower
Body is furnished with hot blast stove system, and a part in the hot wind of hot-blast stove generation is delivered in transition cooling section, guarantees that transition is cooling
Temperature in section.It is also possible to after bringing-up section, from the gas of bringing-up section heat gas outlet discharge, since the position is arranged
Gas out still has 200 DEG C or more of temperature, and it is cold that a part of the gas of heat gas outlet discharge is delivered to transition
But the heat preservation transition to active carbon is carried out in section.It can also be external heat preservation gas, as long as can guarantee in transition cooling section
Temperature be 150-400 DEG C.
Preferably, the gas being discharged out of transition cooling section, can be delivered to the upper section of bringing-up section or by first
Pipeline is fed directly to hot-blast stove；There are also utilized the gas of heat to pass through transition cooling section gas transition cooling section
Body exports direct outlet, can be with outlet after having utilized its waste heat since the efflux gas does not generate additional pollutant.
Therefore in this application, the setting of transition cooling section and the second changeover portion will can effectively be in cooling section upper end
It has parsed active carbon (or active carbon in First Transition section) to be isolated with cooling air by space, to prevent
Parsing active carbon is cooled in cooling section upper section, and condensation vapor leads to fouling.
In the present invention, the high-temperature gas that hot-blast stove is accessed in transition cooling section can make the temperature in transition cooling section high
In the temperature in cooling section, i.e. temperature in transition cooling section is higher than the temperature in heat exchange cooling section, and having parsed active carbon will not
It can be in cooling section upper perforated plate condensation liquid water and ammonium salt crystal.
In the present invention, transition cooling section, the second changeover portion collectively constitute " buffer area ", it is possible to prevente effectively from such as Fig. 8 institute
Active carbon " bridging " situation shown.Novel absorbent charcoal Analytic Tower of the invention, due to being provided with transition cooling section, the second transition
Section occurs the case where " bridging " when the active carbon in First Transition section enters cooling section (transition cooling section of the invention), by
In lower section there are also the second changeover portion and heat exchange cooling section, active carbon is holostrome active carbon state, the second mistake in the second changeover portion
The active carbon for crossing section and exchanging heat in cooling section can still play the role of material envelope, avoid air and enter high temperature active charcoal area
Domain.Further, since the presence of transition cooling section, even if the case where " Tower Bridge " occurs in the active carbon of " bridging ", active carbon directly falls
It falls, since transition cooling section can play the effect of heat preservation and temperature buffer, the active carbon in the second changeover portion still has 200
DEG C or more high temperature, also avoid be discharged out of First Transition section 400 DEG C or more of high temperature active charcoal and directly drop to 100 DEG C of left sides
On right active carbon, so as to avoid the sharp temperature drop of active carbon.
Using novel absorbent charcoal Analytic Tower of the invention, can occur condensing shape in First Transition section to avoid resolution gas body
Condition avoids active carbon structure in Analytic Tower, prevents or significantly reduce the generation of corrosion；Simultaneously as transition cooling section,
The presence of " buffer area " that the second changeover portion is constituted, avoids high temperature active charcoal and directly falls to parsing tower bottom, it is therefore prevented that high
Warm active carbon is contacted with oxygen content air abundant, so that the spontaneous combustion for effectively preventing active carbon occurs, ensure that Analytic Tower
