Nitrogen discarded object（Diseased organ, nitrogenous medicine etc.）When content is higher, clean-up effect of the present utility model becomes apparent, not only can be compared with
Thoroughly to remove chloride, the nitrogen-containing pollutant of tail gas middle and high concentration, reduce environmental pollution, moreover it is possible to realize that the synchronization of the two takes off
Remove, simplify tail gas clean-up technique.
Brief description of the drawings
Fig. 1 is the structure that exhaust gas purification system was burned, was pyrolyzed in the Biohazard Waste described in the utility model based on fuse salt
Schematic diagram.
Embodiment
The technical solution of the utility model is further discussed in detail with reference to embodiments, but it is of the present utility model
Protection domain is not limited thereto.
Embodiment 1
As shown in fig. 1, a kind of Biohazard Waste based on fuse salt burns, is pyrolyzed exhaust gas purification system, and it includes logical
Cross the flue gas quenching tower 1, sack cleaner 3, the first dehydrater 5, molten salt reaction device, spray column 11, that pipeline is sequentially connected with
Two dehydraters 12 and Roots's air-introduced machine 13.It is provided with pipeline between flue gas quenching tower 1 and sack cleaner 3 to add work
The feeding screw 2 of property charcoal.
The quantity of the molten salt reaction device is two, is the first molten salt reaction device 7 and the second molten salt reaction respectively
Device 9, two molten salt reaction devices are connected in parallel, the using and the reserved.First molten salt reaction device 7 and the institute of the second molten salt reaction device 9
Pipeline on be respectively equipped with the first valve 6 and the second valve 8, to control gas path on-off.Above-mentioned cleaning system also includes the
One shunt valve 4 and the second shunt valve 10；The both ends of first shunt valve 4 are connected in parallel with sack cleaner 3（Can be according to both ends
Pressure difference control the safety valve to be opened and closed）, between one end of second shunt valve 10 and molten salt reaction device and spray column 11
Pipeline connects, the pipeline connection between the other end and the second dehydrater 12 and Roots's air-introduced machine 13（Can according to the pressure difference at both ends come
Control safety valve opening and closing）.Shower is installed, for absorbing the alkali particle carried in gas in spray column.
Biohazard Waste burning, the method for being pyrolyzed tail gas clean-up are carried out using said system, it is into molten salt reaction device
Add fuse salt（NaOH+Na2CO3, contents of the NaOH in fuse salt is 60wt%）And molten condition is heated to, by medical waste
Thing burns, pyrolysis tail gas introduces flue gas quenching tower and is cooled to less than 200 DEG C, and the tail gas after cooling removes through sack cleaner
After large-size particles thing, the first dehydrater remove moisture, react removing pollutant into molten salt reaction device, and removing is dirty
Tail gas after dye thing is sequentially discharged after spray column and the second dehydrater.Detailed process is as follows：Tail gas is from medical castoff burning
Stove, pyrolysis oven discharge, its temperature is about 300 ~ 600 DEG C.In order to reduce the generation of bioxin, tail gas initially enters flue gas quenching tower
1, less than 200 DEG C are rapidly cooled to, cooling water used is industrial water.Tail gas after cooling and the work from feeding screw 2
Property charcoal mixing, the wherein less particulate matter of particle diameter is adsorbed in activated carbon, after sack cleaner 3 is entered, the big grain in tail gas
Footpath particulate matter and activated carbon are removed.After the water removal of the first dehydrater 5, tail gas enters the first molten salt reaction device 7, tail gas
In chloride, nitrogen-containing pollutant and fuse salt react generation villaumite, nitrate etc., if at the same time containing CO in tail gas,
Then CO and molten salt reaction generation H2, thus while pollutant is removed, tail gas is had certain value.When
When one molten salt reaction device 7 reaches saturation, switching gas circuit uses the second standby molten salt reaction device 9（First molten salt reaction
Saturation fuse salt in device 7 empties, add new salt, bases melted as fuse salt and being heated to it is standby）.It is anti-from fuse salt
The gas for answering device to export enters spray column 11, salt, the bases particle carried in gas is removed using industrial Water spray, then be passed through
Discharged after the water removal of second dehydrater 12.
Experiment effect is verified：Using the remarkable box Muffle furnace of QSXL-1230 types atmosphere protection, 800 DEG C are warming up to, will be certain
Biohazard Waste after amount crushes is put into stove, and being passed through air makes its sustained combustion, the gas after burning is passed directly into is
The flue gas quenching tower 1 of system, HCl, NOx, HCN concentration after purification in gas are continued to monitor in the top of the system, end.As a result
Display：HCl concentration reaches as high as about 6100ppm in non-purified preceding gas, and NOx is up to about 2450ppm, and HCN is up to about
950ppm, and HCl, NOx, HCN are not detected in gas after purifying（The detection lowest limit is 0.1ppm）.The result shows this reality
There is significant removal effect for high concentration HCl, NOx, HCN in Biohazard Waste combustion tail gas with novel system.
In summary：Tthe utility model system can effectively improve the purification efficiency that Biohazard Waste is burned, is pyrolyzed tail gas,
Simplify purification process technique：When tail gas is chloride, nitrogenous pollution concentration is higher, advantage becomes apparent, and only need to change and add in time
Fuse salt can is added to meet the pollutant removing of higher concentration, supreme limit value.Tthe utility model system also by the dechlorination of tail gas,
Denitration is integrated in same step and completed, and technological process is simpler.In addition, causticizing process can be used after molten salt reaction saturation（Papermaking
The bases reclaiming technique that industry is widely used）Regeneration, regenerates bases by carbonate therein, makes fuse salt again
It can recycle.
Above-described embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any new to this practicality
Scheme after type simple transformation belongs to the scope of protection of the utility model.
