Description
Technical field
The utility model is related to waste incineration and generating electricity field, more particularly to the dry method injection equipment in fume treatment.
Background technology
After flue gas produced by waste incineration is exchanged heat, the processing of its flue gas is a vital processing step,
It is denitration, depickling, dedusting that current processing mode, which is all arrived, but for the flue gas produced by waste incineration, it is necessary to design a kind of work
Make more reliable and more stable calcium hydroxide injection equipment.
Utility model content
Technical problem to be solved in the utility model is to realize that a kind of stable and reliable in work, guarantee flue gas and calcium hydroxide fill
Divide catalytic injection equipment.
To achieve these goals, the technical solution adopted in the utility model is：Flue gas of refuse burning processing dry method is sprayed
Mechanism is penetrated, is located at for spraying the nozzle of calcium hydroxide in the flue between reaction tower and deduster, the calcium hydroxide, which is deposited in, to be deposited
In warehouse, the storage silo bottom connection spiral conveying mechanism top, the spiral conveying mechanism end is provided with blower fan, the wind
Machine is by the air-flow containing calcium hydroxide through pipeline to nozzle.
The nozzle is located at flue center, and the nozzle spray direction is identical or opposite with flow of flue gas direction.
The nozzle is made up of horn-like jet with the conical lead for being fixed on jet center, the lead
Annular airflow outlet is constituted between edge and jet, the tip of the lead is towards jet outer end.
The nozzle is located at before sack cleaner.

The utility model has the advantage of the injection calcium hydroxide that dry method injection equipment can be reliable and stable, depickling can be played
And the dual purpose of protection deduster, so that it is guaranteed that flue gas reaches discharging standards.
Brief description of the drawings
The mark in the content and figure of every width accompanying drawing expression in the utility model specification is briefly described below：
Fig. 1 is dry method injection equipment structural representation；
Mark in above-mentioned figure is：1st, nozzle；2nd, flue；3rd, blower fan；4th, conveying worm；5th, storage silo；6th, compress
Air Fluidized device.
Embodiment
As shown in figure 1, flue gas of refuse burning processing dry method injection equipment is provided with the nozzle 1 for being used for spraying calcium hydroxide, spray
Mouth 1 is located in flue 2 between reaction tower and deduster, and calcium hydroxide is sprayed by nozzle 1, calcium hydroxide and flue gas in flue 2 with
The speed hybrid reaction of high mass transfer, to remove the sour gas in flue gas (such as SOx and HCL), can further remove flue gas
Middle sour gas.
Deacidification is main to be carried out in cloth bag surface, i.e., nozzle 1 is located at before sack cleaner.Therefore use conical head duct type
Dispersing nozzle 1, nozzle 1 is made up of horn-like jet with the conical lead for being fixed on jet center, lead edge
Annular airflow outlet is constituted between jet, the tip of lead is towards jet outer end, the calcium hydroxide so ejected
It can be in dispersion shape, be distributed more uniform.
Nozzle 1 is located at the center of flue 2, and the injection direction of nozzle 1 is identical with flow of flue gas direction or on the contrary, by calcium hydroxide
Uniformly it is injected in flue 2 and adsorbs in cloth bag surface.Because the internal corrosion of flue 2 is big, abrasiveness big, nozzle 1 and insertion
Section of tubing uses 316L heavy wall stainless steel tubes.This shower nozzle has resistance small, and the powder of ejection is evenly distributed, and can be used to spray and disappears
The digestion reaction things such as lime, activated carbon.
Calcium hydroxide is deposited in storage silo 5, and calcium hydroxide injects calcium hydroxide storage silo 5, storage silo 5 by transport vehicle by pipeline
Bottom connection conveying worm 4 structure top, screw rod of the structure of conveying worm 4 in pipeline and pipeline is constituted, and screw rod has electricity
Machine is driven, and calcium hydroxide is transported out out of storage silo 5 come the structure end of conveying worm 4 is temporary provided with calcium hydroxide by screw rod
Space, space side is provided with blower fan 3, and the entrance of blower fan 3 is connected input air, the air outlet of blower fan 3 drum into temporarily providing room with the external world
Wind, by the air-flow containing calcium hydroxide through pipeline to nozzle 1.To avoid the structure of conveying worm 4 from blocking, the bottom of storage silo 5 is set
There is compressed air fluidizer 6, to the bottom blast of storage silo 5, it is ensured that the normal transport of calcium hydroxide.
In order to further control the amount of being blown into of calcium hydroxide, make needed for calcium hydroxide both can guarantee that depickling, to be also avoided that excessive wave
Take, induction installation of the top of flue 2 provided with collection acid gas emissions concentration, i.e., on the basis of flue gas direction in flue 2, sensing
Device is located at the front of nozzle 1, and induction installation exports induced signal to controller, and controller is according to sour gas such as SO2, HCL
Concentration of emission, the consumption of on-line control slaked lime powder (Ca (OH) 2), i.e. controller o controller signal to conveying worm
4, regulation motor rotating speed can play depickling and protect the dual purpose of deduster, so that it is guaranteed that flue gas reaches country's discharge mark
It is accurate.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model is implemented not by above-mentioned
The limitation of mode, if the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or not
It is improved by the present invention design and technical scheme directly apply to other occasions, protection domain of the present utility model it
It is interior.
