DEG C range, it is ensured that avoid the temperature section that 200-500 DEG C of dioxin synthesizes again.
Flue gas after UTILIZATION OF VESIDUAL HEAT IN enters chilling tower 412, and 412 top of chilling tower is equipped with twin spray gun, water and pressure
Contracting air enters chilling tower 412 by certain proportion atomization, the straying quatity of water is controlled by way of automatic control, by flue gas
Temperature was down to 200 DEG C hereinafter, the temperature section that dioxin synthesizes again can be avoided, to reach by 500 DEG C in 1 second sharply above
Inhibit the purpose of dioxin regeneration.The flying dust of greater particle size falls into tower bottom in flue gas, drains into flying dust collecting bag by unloading valve
It is interior.
S4, flue gas emission after cooling is subjected to depickling processing into dry-process deacidification tower 413, dry-process deacidification tower 413 passes through
Plate-like rotates conversion system for calcium hydroxide dosing, so that sour gas and alkaline calcium hydroxide is come into full contact with neutralization, to reach neutralization
The purpose of sour gas in exhaust gas.It can be set metering device in dry-process deacidification tower 413, according to S, Cl, F in material etc. when operation
Content is set the amount of injection of calcium hydroxide by conversion system, can guarantee the amount of injection of operational process medium-slaking lime, effectively to go
Except sour gas.
S5, then flue gas is successively passed through in activated carbon adsorption device 414 and bag filter 415, inhaled by active carbon
Adsorption device 414 and bag filter 415 consolidate object and metal ion to remove most of particle in flue gas, it is preferred that cloth bag removes
Dirt device 415 can use pulsed bag filter 415, and by the step, efficiency of dust collection is up to 99.5% or more, metallic
Removal efficiency is up to 90% or more.
S5, the flue gas after bag-type dust is successively passed into level-one wet process extracting tower 421 and second level wet process extracting tower
It is neutralized in 422, specifically, the mode of the antalkalis such as spray sodium hydroxide can be used to neutralize in flue gas
The dosage that neutralizer can be adjusted according to pH value can not be advantageous in that by the sour gas of dry process, wet process depickling, wherein
PH can be measured by pH detector, which may be disposed at level-one wet process extracting tower 421 and second level wet process depickling
In tower 422.
S6, the flue gas after neutralisation treatment is successively passed through into demister 510, flue gas heater 520, is then passed through
Chimney 530 discharged, it is possible to reduce or the flue gas of discharge is avoided to form misty rain white haze.
The application is by combining dry-process deacidification and wet process depickling, and dry-process deacidification high-efficient, equipment at low cost is simple, dimension
Repair easy, low cost, can be gone out most of sour gas in flue gas by dry-process deacidification, by wet process depickling to cigarette
The acidic materials of gas are accurately neutralized, and have greatly saved cost while obtaining good deacidification effect.
The application makes 300 incineration temperature of dual firing chamber be strict controlled in 1100 DEG C or more, in furnace by setting dual firing chamber 300
The concentration of CO is in 50ppm, O2Concentration 6% or more, flue gas in the combustion chamber the residence time at 2 seconds or more, to make easy life
At PCDD the objects such as PCDF can decompose completely.
Temperature by controlling 411 exit of waste heat boiler is greater than 500 DEG C, can be to avoid oneself decomposes under the condition of high temperature two
It dislikes English to be synthesized again in low-temperature zone, quenching apparatus is set after waste heat boiler 411, makes flue gas in the short time by water spray
It is interior, 200 DEG C are deteriorated to less than from the temperature greater than 500 DEG C, prevents dioxin from synthesizing again.
In order to avoid some uncertain factors, reduction PCDD as far as possible PCDF etc. to the issuable pollution of environment, will
Exhaust gas is discharged into dry-process deacidification tower 413 after chilling, and calcium hydroxide is added in dry-process deacidification tower 413 and removes sour gas, in cloth bag
Activated carbon adsorption device 414 is added before 415 entrance of deduster can inhale the poisonous and harmful substances such as dioxin and heavy metal
It is attached, then discharged after bag-type dust collector is handled.The application is 98% to the removal rate of dioxin in flue gas.
Above embodiments are only to absolutely prove preferred embodiment that is of the invention and being lifted, and protection scope of the present invention is not
