Description
Technical field
The invention belongs to the technical fields of incineration flue gas processing, burn dioxin in flue gas more particularly to a kind of inhibition
Generating device and its application method.
Background technique
It is most thorough, quick and economic method, rubbish, sludge and dangerous waste to burn the solidification disposal of waste for core
Object is one of current city production, the main method of domestic rubbish disposal by burning disposal；In addition, with environmental requirement and phase
The promulgation successively of thermoelectricity industrial policy is closed, Thermal Power Generation Industry increases sludge successively and mixes burning project, so that electricity power enterprise can not only change
At " policy " property power plant, while helping to improve the value of survival of power plant.But the shortcoming of incineration technology is mainly reflected in
There are poisonous and hazardous substance in incineration flue gas, especially for consolidating there are plastics or chlorine element in the solid material of burning
Body substance, in the flue gas that such solids discharges after burning, the equal extremely toxic substance dioxin containing various concentration.Mesh
Before, the main minimizing technology of dioxin is to pass through active carbon using the method for bag filter leading portion injection active carbon in flue gas
Adsorption capacity and reduce the dioxin concentration in flue gas.This method is lower to the removal efficiency of dioxin, normally no higher than
50%；In addition, the dioxin of severe toxicity is only transferred among solid phase from gas phase, is not removed fundamentally by the method
Dioxin.
About the formation source of dioxin, in the combustion process being commonly recognized at present there are three types of the sources of dioxin
: (1) there is dioxin substance in itself, be not destroyed in combustion in dominant mechanism, thus after being present in burning in fuel
Flue gas in；(2) in the case where incomplete combustion, fuel generates part cyclic annular predecessor similar with dioxin structure, this
A little predecessors pass through the destructing or recombination of molecule, synthesize dioxin again with gas phase；(3) out-phase occurs for solid ash surface
Catalysis reacts and synthesizes dioxin.In summary three kinds of mechanism when burning condition is severe, will form a large amount of dioxin in flue gas
Predecessor, so the dioxin in flue gas is mainly obtained by gas phase reaction；In the preferable situation of burning condition, flying dust table
The dioxin that the heterogeneous catalytic reaction that face occurs generates will play main function.So whether sufficiently no matter burning, effectively control
As main chlorine atom in predecessor or heterocatalysis, will play an important role to the concentration of dioxin in discharge flue gas.
Chinese invention patent CN201510552021.9 describes a kind of inhibition solid waste incineration fume dioxin object
The method that matter generates, this method, which introduces 450~500 degrees Celsius of flue gas, inhibits reactor, makes the chlorination in flue gas particles
Copper is reacted with inhibitor mixed is converted into metaphosphoric acid copper, and inhibitor is ammonium dihydrogen phosphate, and when use needs and water is according to mass ratio
1:4 is uniformly mixed.The shortcoming of such technique is: it is relatively partially expensive as the price of inhibitor using ammonium dihydrogen phosphate,
The operating cost of device certainly will be increased in this way.Ammonium dihydrogen phosphate and water are mixed into slurry according to 1:4 and are sprayed, and manage increasing
Road and the risk for inhibiting filler blocking in reactor, and since the specific surface area of slurry like material is limited, therefore influence itself and flue gas
The reaction of middle copper chloride.
Chinese invention patent CN201710038777.5 describes a kind of sodium bicarbonate dry-process deacidification technique, the technique by
One grinder of sodium bicarbonate storage tank lower disposed, is ground into molecule for coarse granule sodium bicarbonate.Boiler come out flue gas,
Sodium bicarbonate, active carbon by grinding enter reactor tank together and are chemically reacted, and then cooperate the reaction of flow-guiding structure design
Device and novel cyclone type bag filter, so that the depickling efficiency of dust collection of whole system greatly improves.Although such technique
Inhibitor is ground, but the micro mist that process of lapping generates is not collected and transportation problem is described, is i.e. small micro- of partial size
Powder is collected and transportation problem is one of key problem of this technology.Secondly, micro mist, active carbon and the flue gas of grinding, only
It is the abundant reaction being unable to ensure in reactor tank by flow-guiding structure, because the micro mist of grinding is easy to, there is a phenomenon where glue wall.
Finally, flue gas to be introduced to the reactor tank that novel spiral-flow type bag filter is arranged, the drag losses of flue gas certainly will be increased, from
And increase the operation consumption of rear end air-introduced machine.
