There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Obtain other attached drawings according to these attached drawings.
Fig. 1 is the schematic diagram of incineration flue gas of household garbage processing system/technique of the present invention；
Fig. 2 is the schematic diagram of waste water treatment process in the present invention.
Specific implementation mode
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Referring to Fig. 1, a kind of incineration flue gas of household garbage processing system provided by the invention, including what is be sequentially arranged desilt dress
Set 1, water bath device 2, trickling 3, adsorbent equipment 4, except CO devices 5, except smelling device 6, electrostatic precipitator 7 and tapping equipment
8；
Desludging device 1, passes through pipeline and garbage combustion device（It is not shown）It connects, flue gas caused by waste incineration enters and desilts
In device 1, the dust contained by flue gas, rising vapor, tar can be combined into sludge, so first having to by desilting dress
It sets 1 to be desilted, otherwise the operational effect of unfavorable follow-up equipment；Using precipitation chamber and maze-type structure, reduce flue gas flow rate and
Temperature reduces ascension kinetic energy；
Water bath device 2 may be used the modes such as spray, aeration and realize water-bath process, further reduce tiny grit, through water
The gas of bath enters trickling 3, and generated waste water can carry out wastewater treatment；
（After desludging device 1 and water bath device 2, the harmful substance of particle form can reduce 80% in flue gas.Wherein bioxin
The form of being primarily present is exactly to be attached on dust particles.But other harmful substances, especially some volatile organic nuisances
Matter, as benzene and benezene material still remain）；
Trickling 3 may be used the equipment realizations such as vertical drop filter tower, formula of rising as high as the banks filter tank and be filtered to the drop of organic exhaust gas, and use is aerobic
Activated sludge process is degraded.Purpose is further to eliminate acetic acid, formic acid, phenyl ring class volatile organic content；
The sorbing materials such as activated carbon, activated coke may be used in adsorbent equipment 4, after trickling 3, remaining harmful substance
It is reduced again by sorbing material；
Except CO devices 5, since the burning of house refuse is in hypoxemia imperfect combustion state, flue gas will produce a large amount of CO（One oxygen
Change carbon）, so needing to carry out high-temp combustion, so that CO is decomposed, such as high temperature combustors can be used, in-built electrical heated filament, quartz ampoule etc.
Electric calorifie installation makes CO resolve into water and carbon dioxide；
Except device 6 is smelt, due to that, with taste is charred after burning, can affect to ambient air, be smelt so need to eliminate in flue gas
Source, such as UV may be used（Ultraviolet light）Fluorescent tube generates ozone and is smelt to realize to remove；
（Through test of many times, detection, after above-mentioned technological process, the flue gas that distributing consumer waste incineration generates substantially eliminates
Harmful substance, especially bioxin can reach the standard that country is less than 0.1ngTEQ/M3）；
Electrostatic precipitator 7, by dusty gas by being electrically isolated when high-voltage electrostatic field, grit and negative electricity in anion junction belt
Afterwards, tend to anode surface electric discharge and deposit.To make the dust in flue gas realize further removal；
Tapping equipment 8, exhaust gas after processing, is expelled directly out by tapping equipment.
Based on above-mentioned incineration flue gas of household garbage processing system, it is formed by incineration flue gas of household garbage treatment process, is wrapped
Include following steps：
（1）, by flue gas caused by garbage incinerating system pass through seal pipeline access desludging device 1；
（2）, access water bath device 2 after desludging device 1, flue gas is removed in water bath device 2 most of to be existed in granular form
Harmful substance；
（3）, trickling 3 is accessed after water bath device 2, flue gas is removed volatile organic content in trickling 3；
（4）, access adsorbent equipment 4 after trickling 3, adsorbent equipment 4 is by noxious substance remaining in flue gas；
（5）, after adsorbent equipment 4 access remove CO devices 5, except CO is resolved into water and carbon dioxide by CO devices 5；
（6）, except after CO devices 5 access carry out flue gas except smelling except device 6 is smelt except smelling device 6；
（7）, be followed by into electrostatic precipitator 7 except smelling device 6, electrostatic precipitator 7 removes the residual dust in flue gas；
（8）, tapping equipment 8 is accessed after electrostatic precipitator 7, through step（7）Treated, and gas is discharged from tapping equipment 8.
Due to by containing the nuisances such as a large amount of tar, dust, particles for floating suspended states in the waste water of water bath device 2
Matter, so must be detached suspended matter by technological means, closed to seal up for safekeeping, the waste water treatment process of use is as shown in Figure 2；
Also access has water tank after the water bath device 2, carries out wastewater treatment, includes the following steps：
（1）, floating material separation：Water tank of the access for wastewater treatment, water tank detach floating material after water bath device 2（It utilizes
The modes such as labyrinth type laminar flow baffle, precipitation, negative-pressure ward）；
（2）, filtering：Input can absorb the additive of harmful substance in water tank, for example add white oil（Paraffin oil）, Neng Goujia
Fast harmful substance aggregation；Citric acid is added, sulfur dioxide of degrading；
（3）, absorption：Harmful substance in water tank is adsorbed.For example activated coke, activated carbon, organic film, electrodeless pottery can be used
Porcelain film or other porous materials are absorbed and filter, and harmless treatment is done；
（4）, cycle：Water after absorption is passed through water tank again and carries out reuse；
（5）, recovery processing：Because water accommodates the saturation upper limit for harmful substance, and has vapor in burning process
It retains, so should be regularly replaced for the water in water tank, the water recycling after using, at dangerous bazardous waste concentration
Reason.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
