Description
Technical field
The utility model belongs to flue gas pollutant field of purification, in particular to the dioxin of a kind of applications catalyst removes dress
It sets.
Background technique
Dioxin is often referred to the plane arene compounds that there is the chlorine more than one group of similar structure and physicochemical property to replace, and belongs to
The oxygen-containing thrcylic aromatic hydrocarbon class compound of chloro, International Cancer Research Center have been classified as mankind's level-one carcinogenic substance.In atmospheric environment
The complicated multiplicity in dioxin source, mainly there is a consumer waste incineration in the higher source of attention rate, and danger wastes burn, cement kiln
Cooperative disposal solid waste, steel sintering etc..The emission behaviour of this kind of toxic pollutant of dioxin is by social concerns, in the public
The field of household garbage incineration most paid close attention to, the dioxin limit value in the incineration flue gas of household garbage in China are 0.1ngTEQ/
Nm3, it is consistent with the standard of European Union, Japan, it is that the world is most tight.The current standard that danger wastes burn is GB18284-2001,
The discharge standard of dioxin is 0.5ngTEQ/Nm3, but newest dangerous waste incineration contamination control standard (exposure draft) is
It is down to 0.1ngTEQ/Nm3。
For active response country, international every environmental protection policy, while considering in addition for public physical and mental healths, needs
To control increasingly strictization of dioxin, combustion apparatus, device mass upgrade optimization to dioxin is generated, by dioxin
Concentration of emission controls within the scope of most strict standard.Control for dioxin is primarily present the control hardly possible in combustion apparatus
Degree is big, temperature change when easily decompose and the problems such as active carbon removing is costly, therefore research and develop a kind of whole investment it is small, two
Dislike English removal efficiency it is high, without being transformed to existing equipment, system simply there is good economic benefits and environmental benefit
Dioxin removing means is of great significance.
Utility model content
The purpose of this utility model is easy when being directed to big fluctuation when current dioxin controls in combustion apparatus, temperature change
It decomposes and active carbon removes the problems such as costly, and a kind of dioxin removing means of applications catalyst is provided.
In order to solve the above technical problems, the technical solution adopted by the utility model is: a kind of dioxin of applications catalyst
Removing means, its main feature is that: including combustion apparatus, catalyst module, tail portion heat transfer flue, pollutant process equipment and chimney；
The top exhanst gas outlet of the combustion apparatus is fixedly connected with the top gas inlet of tail portion heat transfer flue by flue；
The catalyst module is arranged in the heat transfer flue of tail portion and is fixedly connected by steel plate with the shell of tail portion heat transfer flue；Institute
The lower part exhanst gas outlet for the tail portion heat transfer flue stated is fixed with the top gas inlet of pollutant process equipment by flue
Connection；The lower part exhanst gas outlet of the pollutant process equipment and the lower part gas inlet of chimney connect by the way that flue is fixed
It connects.
Preferably, the combustion apparatus is domestic waste incineration, danger wastes incinerator, cement kiln synergic processing
Any one in solid waste sintering furnace or steel sintering furnace.
The catalyst module can also be 2 layers or multilayer.
The pollutant process equipment be sulfide removal equipment, nitrogen oxides treatment equipment, dust processing equipment with
And any one in dioxin advanced treatment device or multiple pollutant Combined Treatment equipment.
Compared with prior art, the utility model has the advantages that
1, the utility model only needs to install a small amount of catalyst module additional in the heat transfer flue of tail portion, without to existing equipment into
Row transformation, system are simple and reliable.
2, the entirety of the utility model invests that small, operation expense is low, can substantially reduce at the pollutant of follow-up link
The reason equipment additional amount of active carbon in the process deep-controlled to dioxin saves subsequent dioxin advanced treating link completely,
With good economic performance.
3, the utility model can effectively solve dioxin and control the difficulties such as fluctuation is big, temperature change is easily decomposed in combustion apparatus
It is difficult to the advanced treating of dioxin to the preliminary control difficulty of dioxin and follow-up link in the process to alleviate combustion apparatus for topic
Degree can realize largely controlling and removing to dioxins in flue gas when flue gas flows through catalyst module position, have good ring
Guaranteed cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of dioxin removing means of applications catalyst comprising combustion apparatus 1, catalyst module 2,
Tail portion heat transfer flue 3, pollutant process equipment 4 and chimney 5；The top exhanst gas outlet of the combustion apparatus 1 and tail portion exchange heat
The top gas inlet of flue 3 is fixedly connected by flue；The catalyst module 2 is arranged in tail portion heat transfer flue 3
Interior and process steel plate is fixedly connected with the shell of tail portion heat transfer flue 3；The lower part exhanst gas outlet of the tail portion heat transfer flue 3 with
The top gas inlet of pollutant process equipment 4 is fixedly connected by flue；The lower part of the pollutant process equipment 4
Exhanst gas outlet is fixedly connected with the lower part gas inlet of chimney 5 by flue.
Combustion apparatus 1 described in the present embodiment uses domestic waste incineration.
The catalyst module 2 can also be 2 layers or multilayer.
Pollutant process equipment 4 described in the present embodiment is multiple pollutant Combined Treatment equipment.
Combustion apparatus in the present embodiment can also use danger wastes incinerator, water other than domestic waste incineration

Any one of sulfide removal equipment, nitrogen oxides treatment equipment, dust processing equipment and dioxin advanced treatment device
Instead of.
When operating normally, domestic garbage burning, danger wastes etc. produce package unit in combustion apparatus 1 in the present embodiment
Raw flue gas pollutant successively by 3 upper section of tail portion heat transfer flue, the catalyst module 2 being arranged in inside tail portion heat transfer flue 3,
3 lower section of tail portion heat transfer flue, pollutant process equipment 4 and 5 heel row of chimney are into ambient air；Domestic garbage burning, danger are useless
The flue gas pollutant of the generations such as gurry is carried out first in combustion apparatus 1 by production quantity of the adjustment of ignition temperature to dioxin
Control, followed by flue gas flows through a large amount of by the effect dioxin of catalyst when the catalyst module 2 in tail portion heat transfer flue 3
Decompose, substantially reduce the content of dioxin, be finally flue gas flow through follow-up link pollutant process equipment 4 when in flue gas
Other pollutants carry out purified treatment, while to dioxin when flowing through front end combustion apparatus 1 and catalyst module 2 according to flue gas
Situation is removed, considers whether spray a small amount of active carbon in flue gas dioxin to be removed in depth, and then realizes that two dislike
The qualified discharge of English realizes the qualified discharge of entire flue gas pollutant.
