High-temperature flue gas dust and nitrogen oxides cooperative control system of the present utility model, advanced and reasonable design, technological process It is easy and effective, dedusting and denitration function are concentrated on filter bag, it is synchronous to dust and nitrogen oxides high in same technological process Effect removing, fully realizes the purification technique of the denitration dust collecting integral of flue gas;Significantly, land area significantly reduces energy-saving effect, Financial cost is greatly reduced, it is adaptable to pushed away using the coal-burning boiler and similar operating mode of dust, nitrogen oxides as main pollutant Wide application;Dedusting, the flue gas purification system of denitrification integral, without changing original dust pelletizing system, as long as carrying out simple whole Change, change inorfil film covering function filter bag, you can realize the purification technique of dedusting and denitrification integral;It is of the present utility model to remove When dirt, the flue gas purification system work of denitrification integral, first removed by the microporous teflon membran of inorfil membrane bag filter Dust in flue gas, the denitrating catalyst then loaded again by filtrate removes nitrogen oxides, can effectively reduce denitrating catalyst Blocking, abrasion, denitration efficiency can reach 65%-80%, the catalyst service life of filter bag and its load 4 years with On;The heater outlet temperature is 180-280 DEG C, preferably 200-260 DEG C, is more beneficial for the removing of nitrogen oxides.
Brief description of the drawings
Fig. 1 is the structure structure chart of the utility model product.
Embodiment
Below in conjunction with the accompanying drawings, detailed explanation is carried out to the utility model.
The utility model discloses a kind of high-temperature flue gas dust and nitrogen oxides cooperative control system, high-temperature dusty gas from Boiler 1 and preheater 2 flow out, and the flue-gas temperature flowed out from preheater 2 is 200 DEG C, and the temperature is conducive to the removing of nitrogen oxides. Enter by admission line 3 in deduster 5 (sack cleaner), while denitration auxiliary agent injection device 4 is provided with admission line, The denitration auxiliary agent is ammonia, and denitration auxiliary agent injection device 4 is used for the injection of ammonia.High temperature dust air-flow is dredged by deflector 6 Flow guide enters dust and gas room 7, while part big dust particle is fallen in ash conveying device 12.Dust-contained airflow covers by inorfil After the filtering of membrane filtration bag 8, the dust in flue gas is trapped within filter material surface, and filter material surface laying dust can cause SR to raise, reach Deashing is carried out by pulse ash remover 11 after to setting value, dust has the unified transport of ash conveying device 12 after dropping.
Air-flow after purification enters what is contained in filtrate, flue gas through the microporous membrane on the surface of inorfil membrane bag filter 8 Nitrogen oxides is under the collective effect of the catalyst for ammonia and the filtrate load that system is injected, the innocuous substance such as generation nitrogen gas and water, Flue gas after purification enters air-purifying chamber 10 via filter pocket mouths, and air-purifying chamber 10 in the middle of dust and gas room 7 with being provided with card 9, for installing Inorfil membrane bag filter 8, purified gas enters chimney 15 by discharge duct 13 under the traction of blower fan 14, is finally discharged into big In gas, it is achieved thereby that the flue gas purification system of dedusting denitrification integral.Denitration efficiency can reach 65%-80% (with denitration Temperature selection is related), the catalyst service life of filter bag and its load can be changed synchronously more than 4 years.The nothing The active nitrogen oxide catalyst of the fiber film-coated filter bag 8 of machine is V2O5
By many experiments data display, when between 220-260 DEG C of the temperature value for the high-temperature flue gas that preheater comes out, The hauling-out rate of nitrogen oxides is higher, is more beneficial for the purification of high-temperature flue gas.The aperture of dedusting filtering bag is defined to 0.1-1 microns of model When enclosing, the removal effect of dust is best in the dust removal efficiency highest of dust, flue gas in high-temperature flue gas, the smoke-purifying discharged into the atmosphere Pollution of the gas to air is minimum.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed Change or replacement, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should This is defined by the protection domain of claims.
